This document discusses progress toward developing efficient models for calculating irradiance on the rear side of bifacial solar panels. It describes existing industry models and two new models being developed and validated at NREL - a ray tracing model and a 2D view factor model. Both NREL models were found to accurately predict rear side irradiance ratios and bifacial performance gains compared to measured data from systems at NREL and SolarWorld, with errors less than 2%. Key parameters like albedo, tilt, and row spacing were found to significantly impact rear side irradiance. The view factor model will be integrated into NREL's SAM tool while the ray tracing model will be made available as a standalone tool.

Cell String-Level Energy Production Simulation with Aurora is powerful software used to create over 10k solar projects per week. It provides the most granular submodule-level modeling to capture partial shading, bypass diodes, and cell string-level power electronics in PV systems. The simulation initializes site and panel configurations in 3D space, computes irradiance and temperature for each cell string, and models each string as an electrical circuit to solve for maximum power point at each hour. Results show cell string-level simulation can improve energy production and lifetime energy bill savings accuracy by 1-4% compared to module-level simulation due to its ability to account for unique string configurations, bypass diodes, and cell string optimizers.

This document summarizes the results of multiple outdoor measurements and modeling of bifacial PV module performance. Outdoor measurements were taken of 12 PV modules in Lugano, Switzerland between 2014-2015. Models were developed and validated to predict cell temperature, irradiation, and power output. The best-fit models estimated bifacial module performance using two parameters for ground-reflected irradiance and could predict power within 4-5 Watts. Further work is needed to improve cell temperature modeling and optimize models for different tilt/azimuth conditions.EFEU / FLEXe Antila Heli in the future it is more important when you use elec...
In the future, when electricity is used will be more important than how much is used due to the intermittent nature of renewable energy sources like wind and solar. Seasonality in renewable energy production and demand will pose challenges that can be addressed through solutions like increased hydro power, combined heat and power systems, battery storage, demand flexibility, and Nordic cooperation. Managing seasonality well will determine how competitive the Nordic energy market remains.

This document discusses the increasing need for flexibility in power systems due to higher levels of variable renewable energy (VRE) like wind and solar power. As the share of VRE increases:
1) Power systems will experience more variability and uncertainty that will require flexible generation sources able to adjust output quickly.
2) New market designs may be needed to separately value flexibility resources able to balance supply and demand at varying output levels.
3) Analyses show flexibility from diverse sources like thermal plants, hydro, demand response and sector coupling between power and heat have increasing economic value for balancing high-VRE power systems in a cost-effective way.

Prism Solar Technologies conducted a multi-year study of bifacial solar module energy gains under various field conditions. The study found that bifacial modules produced significantly higher energy yields than monofacial modules under different tilt angles, heights, albedos, and orientations. For example, at a site in Tucson, AZ with a ground albedo of 77% and module height of 0.76m, the bifacial modules produced 36.8% more energy than the monofacial reference modules. However, standard STC ratings do not accurately represent the true energy generation potential of bifacial modules under real-world conditions.01 roman rudel welcome pvpmc

Holistic District Heating Grid Design with SimulationX & Green City
Buildings are central elements of future smart grids. Heating and cooling demand are predictable within reason, building mass as well as heating and hot water systems provide inherent storage capacity. Additionally, the fluctuation between peak and average power of a building is much more friendly to the grid than of other network nodes like wind power or electric mobility.
A local heating grid partially supplied by renewable solar heat is currently being built in a town in Bavaria. Heat pump systems provide additional storage capacity for electric grid surplus while they serve as wind energy dump for the local utility company. Cogeneration plants and peak-power boilers provide heat and power in times of low energy coverage. The low temperature heating grid supplies decentral heat pumps, which provide required heat at a much higher temperature level to each building.
The paper describes basic modeling aspects for district heating grids with SimulationX & Green City. An interesting solar-aided grid example helps to identify benefits of a new modeling approach.

PVsyst has introduced several new features including the ability to model module degradation over time, simulate battery-based standalone systems using state of charge, and improved 3D modeling capabilities. Upcoming versions will allow modeling of bifacial modules, improved 3D editing tools, support for additional battery technologies, and importing from other CAD formats.
Green fuel technologies
Solar power systems can provide green fuel through solar energy captured from sunlight. The key requirements for a 10 kW solar power plant include 120 square meters of available roof space and adequate sunlight. Such a system could generate 1200-1400 units of electricity annually with a return on investment within 6-7 years, and have a lifespan of 25 years with minimal maintenance needs. Net metering credits system owners for excess solar energy fed back into the main power grid, while gross metering exports all generated electricity to the grid. Government subsidies and tax benefits are available to encourage solar power adoption.
Design Optimization using the Latest Features in HelioScope
Design Optimization using the Latest Features in HelioScopeSandia National Laboratories: Energy & Climate: Renewables
This document discusses the latest features in HelioScope solar design software and their implications for design optimization. It outlines new performance modeling capabilities like spectral adjustment and sub-hourly calculations. Engineering process enhancements include team management, design profiles, and permitting tools. The design environment features improved stringing, AC circuit calculations, 3D modeling, and layout parameters. These updates allow for less reliance on rules of thumb and more complex, optimized designs. The product roadmap indicates expanding LiDAR, optimization incorporating financials, tracker modeling, and advanced inverter modeling.S5 RES Technical Considerations
This document summarizes information about renewable energy and electricity systems. It discusses how renewable energy sources like wind and solar are increasingly contributing to electricity generation capacity but can be intermittent. Concentrating solar power (CSP) with thermal energy storage is presented as the most viable solution currently for providing dispatchable renewable energy on a utility scale. CSP plants can store solar energy as heat and release it to produce electricity when the sun is not available, providing reliability similar to fossil fuel plants. The document argues that for high shares of renewable energy on the grid, dispatchable sources like CSP will be needed to maintain grid stability and reliability in a cost effective way.

The document discusses wind turbine generator classes according to IEC 61400-1 standards. It explains that turbines are designed for specific wind conditions defined by average wind speed, extreme gusts, and turbulence intensity. Higher classes indicate more turbulent wind regimes that turbines must be built to withstand. Turbine classes help determine which turbines are suitable for a given site's normal wind conditions. The standards help ensure engineering integrity and safety of wind turbines during their planned lifetimes under the wind loads they may experience.
SOLAR SITE SURVEY ROOFTOP
The solar feasibility study document discusses the key steps and information needed to conduct a solar feasibility study for both rooftop and ground-mounted solar PV projects. The feasibility study involves collecting site details like available roof or land space, structure details, electrical load details, and interfacing voltage requirements. This information is used to design the optimal solar PV system configuration and ensure any issues are addressed. Component placement, cable routing and distances are also determined to prepare an accurate bill of materials and system cost estimate.
Electrical wind power generation
The document discusses different electrical machines used for wind power generation. It begins with an introduction to wind power production and then describes various electrical generation schemes currently in use worldwide. These include constant speed wind turbines connected directly to the grid, variable speed turbines with a doubly-fed induction generator, and direct drive turbines with a synchronous or permanent magnet synchronous generator. The permanent magnet synchronous generator system directly connected to the grid via a full-scale power converter is highlighted as one of the most promising designs currently used due to its high efficiency and robustness.
Modeling the Irradiance and Temperature Dependence of PV Modules in PVsyst
This document discusses modeling the irradiance and temperature dependence of PV modules in PVsyst software. It presents four modeling approaches: the PVsyst standard model, a "V6 tool" model, an "only G - then T" model, and a "G-T matrix" model. Results show the "only G - then T" and "G-T matrix" models more accurately predict maximum power (Pmax) over varying irradiance (G) and temperature (T) conditions compared to the standard and V6 tool models, with the "G-T matrix" model having the best fit to measurement data overall. Both new models also improve the accuracy of energy yield forecasts for different locations compared to

The document summarizes research on the impact of soiling on PV module performance in various climates. Mini-module tests were conducted over 1-2 years in Tempe, AZ; Chennai, India; Ancona, Italy; Cologne, Germany; and Thuwal, Saudi Arabia. Results showed significant annual soiling losses of over 3% in Tempe and over 2% in Chennai due to dust accumulation between rainfall events. Frequent rainfall in Ancona and Cologne led to negligible losses. Periodic cleaning was found necessary to maintain performance in arid Thuwal. Soiling patterns varied substantially between climates and years.

Short Commercial presentation_ROW.pptx
SolarEdge provides a commercial solar solution that offers four key benefits over traditional inverters: increased energy yield, lower operations and maintenance costs, enhanced safety, and more flexible design. Their solution utilizes power optimizers at the module level and monitoring software to maximize energy production, reduce costs over the system lifetime, and improve safety during installation and maintenance. While their inverters have a slightly higher upfront cost, SolarEdge's end-to-end solution offsets this with reduced balance of system costs, lower maintenance expenses, and increased energy production over time.

Short Commercial presentation_ROW.pptx
SolarEdge provides a commercial solar solution that offers four key benefits over traditional inverters: increased energy yield, lower operations and maintenance costs, enhanced safety, and more flexible design. Their solution utilizes power optimizers at the module level and monitoring software to maximize energy production, reduce costs over the system lifetime, and improve safety during installation and maintenance. While their inverters have a slightly higher upfront cost, SolarEdge's end-to-end solution offsets this with reduced balance of system costs, lower maintenance expenses, and increased energy production over time.

A stand-alone, solar powered commercial bank with EV for public transport
This document proposes a stand-alone solar-powered commercial bank and electric vehicle transport system in Lekki, Lagos, Nigeria. The system is designed to meet the bank's daily energy demand of 288 kWh using 70 kW of solar PV panels and a 400 Ah battery storage system. Simulation results show the system can meet 90-100% of daily demand during dry seasons and 75-90% during wet seasons. An economic analysis estimates a payback period of less than 10 years, making the project economically feasible.
Photovoltaic Installations
Most people are familiar with the phenomenom solar energy in its quality of generating electrical power. Solar electricity may be applied in multiple tools serving a variety of functions. Well-known examples are the pocket calculators powered by a PV-cells and off-grid street lighting and emergency telephones along the highway powered by one or more PV-modules.
Solar energy became known to the ordinary people in the fifties and sixties of last century due to space programs of the Americans, Russians and to a lesser extent other European countries. Satelites and space capsules were installed with solar cells for power supply of its electrical systems. From that time the application of PV moved slowly from extraterrestrial use to terrestrial application. First and also most widespread applied are the off-grid domestic and non-domestic PV systems. Off-grid domestic PV-systems are installed in households and villages not connected to the utility grid. Usually, a means to store electricity is used, most commonly in combination with a lead-acid battery. Off-grid non-domestic PV serves a variety of applications such as water pumping, remote communications, safety and protection devices etc, at locations without the presence of public grid.
Following off-grid PV application, also as a result of the growing attention for renewable energy, from early eighties of last century a tendency could be observed to connect PV systems also to the public grid. Also the field of application moved from undeveloped and rural areas to well developed urban areas equipped with finely meshed public grid..
This webinar gives an overview on PV-systems connected to the public grid.

AS3 cop-21_US
This feasibility study examines a proposed solar self-consumption project for a building called the "House of Enterprises" in Villeneuve-la-Garenne, France. The building currently has high electricity consumption of around 154 MWh per year. A photovoltaic system with two fields totaling 260 square meters would generate an estimated 56 MWh of electricity annually, enough to cover 35% of the building's needs on average. However, the financial analysis shows that with an investment of €240,000, the savings from avoided electricity costs over the system's lifetime would not offset the upfront costs. For the project to be economically viable, energy efficiency upgrades would need to lower the building's consumption first. Currently,

ECI position on the revision of the Energy Efficiency Directive
The European Copper Institute (ECI) supports the EU’s climate ambitions for 2030 and
2050 and welcomes the proposed recast of the Energy Efficiency Directive (EED). Copper is
a key material for energy efficiency in all sectors and contributes significantly to the clean energy
transition as a sustainable raw material that is essential to decarbonise the economy.
The EED recast proposal goes in the right direction in many areas. We welcome the
mainstreaming of the Energy Efficiency First principle and the strengthening of the
exemplary role of public buildings in driving renovation. The revised provisions on energy
audits and energy management systems are also useful to help small and medium-sized
enterprises (SMEs) catch up on energy efficiency measures, although we believe that mandatory
certification can be a barrier to the adoption of energy management systems by SMEs.
However, more needs to be done to facilitate the exploitation of the significant potential for
utilising waste heat from industrial processes under the EED. It is welcome that under the
revised article 23, Member States are mandated to take measures for district heating and cooling
infrastructure to be developed where benefits exceed costs.
However, in many cases it will not be possible to direct industrial excess heat to district heating
networks, and in such cases, the conversion of waste heat into electricity for own
consumption should be explicitly included under EED Article 23 as an energy savings
measure to be considered by Member States in the cost-benefit analyses underlying their
comprehensive heating and cooling assessments, and under Article 24 when assessing the
utilisation of waste heat on-site and off-site when large industrial installations are newly planned
or refurbished.
Finally, it is important to acknowledge that increasing energy efficiency will sometimes have an
impact on the realisation of other environmental objectives, such as environmental protection,
resource efficiency or decarbonisation. In some cases, decarbonisation measures such as
switching to low carbon energy sources or increasing energy system flexibility may reduce energy
efficiency, while the implementation of higher environmental protection standards can increase
energy demand. Policymakers should be mindful of such trade-offs and take care to avoid setting
conflicting targets.
Infographic Energy Efficiency Directive - Waste heat-to-power - European Cop...
The primary route for copper manufacturing releases important amounts of heat. Consequently, ECI had asked to have an explicit recognition of projects recovering and valorising waste heat flows. Such demand has been reflected in the article 23.4 of the directive as follows: “ [...] Member States shall take adequate measures for efficient district heating and cooling infrastructure to be developed and/or to encourage the development of installations for the utilisation of waste heat, including in the industrial sector
European Copper Institute position on Transformers Regulation revision - Sept...
The EU Green Deal aims to establish a general reduction of final energy demand in the decades to come, combined with a shift towards electricity as the main energy carrier. Materialising this ambition will require further efforts to increase energy efficiency, notably in the electricity grid and its applications. In an electricity generation mix dominated by renewables, increasing the energy efficiency translates into savings of material and land use for generation infrastructure as well as for transmission and distribution networks.
Given the increasing share of electricity in final energy demand and its importance in heating and transport, transformers with an increased capacity at limited cost and with minimal size and weight are needed.
The circular economy is a key pillar of the EU Green Deal. The use of materials must be optimised, both by limiting their quantity and by improving their circularity (design-for-recycling).
Taking the above considerations into account, ECI recommends the following measures:
1) Strengthen Minimum Energy Performance Standards (MEPS) of transformers while introducing material efficiency requirements (MMPS). Given the need to further electrify the economy, while at the same time boosting energy efficiency; given the circular economy objectives and the fact that saved energy translates into a reduced need for electrical infrastructure; given the electricity price evolution in the past years and the recent reform of the electricity market design; we believe the minimum level of energy performance for transformers should be re-assessed, while at the same time making sure that the potential new Tier 3 requirements following from this assessment do not lead to an excessive use of materials. A preliminary modelling exercise points to 1.8 TWh/year of electricity savings and a reduction of 0.8 to 1.6 million tons of materials used if Tier 3 requirements were introduced for distribution transformers.
2) Allow flexibility in design. Together with the free choice of active materials, flexible design strategies should be permitted. These strategies create an additional degree of freedom in design, making it easier to respond to MEPS and MMPS requirements, They include approaches such as the Peak Efficiency Index (PEI) in distribution transformers and concepts such as the Sustainable Peak Load (SPL) transformer in less loaded networks.
3) Promote the lowest life cycle cost at system level. Allow transformer owners to make the best decision on the optimal transformer design considering both their expected load profiles and their additional investment costs in substation and cables. Operational costs should be fully considered in the decision-making process. In the case of regulated utilities, a harmonised approach should be implemented by National Regulatory Authorities to minimise net societal costs (lifetime capex + opex).
Induction Motors Matching Permanent Magnet Performances at Lower Costs
Due to a continued concern on the external dependence of permanent magnets in Europe, induction technology is being pushed beyond its limits to maximise performance.
With novel materials, material characterisation and multi-domain design, power-speed capability of laminated rotor induction motors can match that typically associated with surface permanent magnet machines, at a fraction of the cost.
This session reviews the findings relating to lower cost induction motors, highlighting how they can successfully be used as an alternative to permanent magnets.

Fire-Resistant Cable Sizing of conductors supplying electrical equipment that...
The integrity and functionality of the electricity supply cables is vital for keeping safety services operational during a building fire. Choosing a cable that is tested and classified as fire resistant is a first step when designing an electrical circuit to supply equipment that must remain functional during a fire. The next step – equally important – is to calculate the appropriate cable conductor cross section. This requires particular attention because of the fact that electrical resistance increases sharply as temperature rises.
To calculate the electrical resistance under fire conditions, the fire temperature must be known. First, it must be determined for how long the safety services must remain operational. The standard durations of fire resistance classes are 30, 60, 90, and 120 minutes. When this time span is known, the fire temperature can be derived from the standard temperature-time curve as defined in ISO 834. The electrical resistance under fire conditions can then be obtained by applying the Wiedemann-Franz law. This will establish an electrical resistance correction factor which facilitates the calculation of the voltage drop under fire conditions.
The voltage drop over the entire length of the supply cables must be restricted to ensure that fire safety equipment will maintain functionality for the required length of time. Usually, the maximum voltage drop will be specified in the equipment’s user guide. If this is not the case, one must consider a maximum voltage drop of 10%. Because buildings are often compartmentalised into fire zones, cables feeding fire protection equipment are rarely exposed to fire temperatures over their entire length. The part of the cable not affected by the fire will operate at normal temperature, while the part exposed to the fire will have increased resistance. The total resistance over the whole length of the cable is calculated by applying the electrical resistance correction factor only to that part of the cable affected. From the maximum voltage drop of the fire safety equipment, the electrical resistance correction factor and the compartmentalisation of the cable route, the maximum electrical resistance the cable is allowed to have at normal temperature (20°C) can be calculated. The minimum conductor cross section can then be derived from this using Tables 1 to 4 of the international standard EN/IEC 60228, or their equivalent in national standards.
The electrical insulation of fire-resistant cables is designed to withstand extreme temperatures, a fact which could lead to the false assumption that there is no limit to the current-carrying capacity of these cables. In reality, fire-resistant cables are not tested for the potential additional heat produced as a result of the increased electrical resistance at high temperature.
Copper, a Strategic Raw Material - Circularity, GHG Emissions Pathway and Ava...
With its superior electrical conductivity, copper is a key material for the clean energy transition. The fact that the metal is endlessly recyclable without loss of properties is a major trump card in this context. Recycling alone, however, will never suffice to meet the predicted demand growth. There are enough resources on earth to produce the additional copper that is required, but the lead times from exploration to production will have to speed up and to the carbon emissions of copper production will have to be brought down to zero. The copper industry is well on track to deal with these challenges, but the involvement and commitment of multiple stakeholders is needed to make it happen.
Used in a wide variety of electrical applications
Copper has the highest electrical conductivity of all non-precious metals, which is the reason why it can be found in a wide variety of electrical applications. At the side of electricity generation, both photovoltaic and wind power plants contain high quantities of copper. Transformers, batteries and interconnectors are built with copper and play a key role in the electricity grid. Many electrical end-use applications also have copper as key material, including electric vehicles and their charging infrastructure, electric motors, electro-processing systems, heat pumps and heat recovery systems. This makes copper into an essential material to electrify and decarbonise the European economy, with EU copper demand expected to increase by 35% between 2020 and 2050.
Today, 30% of the copper demand in the EU is met through local extraction and processing, 20% through the recycling of local end-of-life products, 30% through the import of copper concentrates, and 20% through the import of refined copper.
Recycling as a major trump card
Copper’s infinite recyclability is a major advantage. About 80 percent of copper is used in an unalloyed form, facilitating the recycling process. Even for copper that is alloyed or contains other materials, recycling without downgrading is still possible and efficient. This means that the unwanted elements can be removed to recover the copper in its pure state, ready to be re-used in any kind of application. In fact, recycled copper and newly mined copper go through the same refining process. Depending on the purity of the scrap, the required processing steps vary, but the end product is always the same and provides the required purity for electrical applications. Because of its high degree of recyclability, the copper in use in its various applications is not lost, but can be considered a legitimate part of the world copper reserve, often referred to as society’s “urban mine”.
Globally, copper demand is expected to double by 2050, driven by the clean energy transition, population growth and economic development. This leads to the question whether copper production will be able to follow this steadily increasing demand.

A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
