The document summarizes the installation of a 12 kW grid-tied photovoltaic array at the Eddlington Centre in Doncaster, UK. The charity that runs the centre wanted to install solar panels to reduce costs and increase sustainability. After assessing the building, DAS Solar proposed a 12 kW system that would pay for itself in under 7 years. The installation required structural upgrades to the roof and electrical upgrades. DAS Solar then installed 48 solar panels across two south-facing roofs and connected them to inverters. The system was commissioned, and the site was handed over with monitoring to be provided for 25 years. The 12 kW system is expected to generate over 300,000 kWh of electricity and save significant costs

Amey PLC has recently completed the core investment programme for Sheffield PFI.
One of the challenges for Amey was the inclusion of about 30 famous listed sewer lanterns and lighting columns distributed throughout the city that were in varying stages of decay. Not only were the columns listed but the residents were fiercely protective of their architectural history and in some cases, had taken charge of the asset themselves.
So, what’s the problem then? Replacement lanterns and a lick of paint should do the trick.
Unfortunately, there was no available electrical supply to most of the columns as most of them were connected to the gas grid, about three still worked.
Though the lighting designs did not rely on the sewer lanterns for light distribution, some vociferous residents had been misinformed that they were going to be replaced with modern LED lanterns and naturally were very concerned as to their impact on the environment.
The costs and associated disruption of connecting electricity supplies to some architecturally sensitive areas together with gas supply company’s concerns in maintaining a safe supply on the street meant an innovative approach had to be taken. This project was originally given to the Electrical Engineering faculty of Sheffield University who were unable to develop a workable solution. Jonathan Skill of Amey then approached Pudsey Diamond Engineering Ltd to see whether their recently solar bollard technology could be adapted and incorporated into the sewer gas lantern to allow the lanterns to be in light.
This was a very significant challenge. English Heritage were concerned that the exterior of the lanterns were not to be altered and further, the lanterns were to be reworked where possible, repaired and not replaced with replicas.
The authors of this paper will explore the significant challenges presented with the audience and demonstrate how leading edge technology of 3D printed gas mantles combined with LED modules driven from innovative and unique solar capture units with energy storage using lithium iron batteries within the lantern allowed this project to be delivered to the satisfaction of English Heritage and the residents of Sheffield.

Maximizing Power Production for Small Commercial Projectsallearthrenewables
For any project, return on investment is key, but this is especially true for small commercial projects, where getting the most bang for your buck is essential. The key is reframing your thinking: it’s not just about traditional measures of cost like dollar per watt. Thinking about production capacity, and your dollar per kilowatt-hour, will yield a much better picture of how your project will return–and how you can meet your bottom line.
In this webinar, we’ll take you through the key steps for maximizing your power production in small commercial projects, including choosing panels that will give you more power for your money, how to site effectively to ensure you’re capturing as much sunlight as possible throughout the day, and thinking beyond fixed-mount systems to systems that follow the sun to increase your production by up to 40%.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

1. THE EDDLINGTON CENTRE
EDDLINGTON LANE
EDDLINGTON
DONCASTER
DN12 1PL G59 APPROVAL FOR A 25,000W GRID-TIED PHOTOVOLTAIC ARRAY
2. THE BRIEF
DAS Solar undertook the feasibility study on the site of a converted Junior school on the outskirts of Doncaster. The
site is now home to a resource and learning centre run by an independent charity. The site was made up of one
building centred on a large open courtyard. Built in the 1930s its structure and composition were the first priority
when assessing the site. The roof is of traditional construction with flat roofed areas covering entrance halls and of
later construction the main joining corridor within the quadrant. The tiled roof was covered with handmade
rosemary type tiles original to the building. Sarking felt under these tiles was absent and there was evidence of
damage on all roofs. The basic structure however was in good condition with no evidence of water ingress, damp or
structural fragility.
The site is in use every day and gets very busy at times. Special attention was going to have to be given to protection
of the general public and staff within. The project would have to go ahead while the centre was still in use.
Return on investment was paramount to the funding of the project. We calculated the system would pay for itself in
less than seven years, a terrific investment for our client.
The electrical system with in building is brand-new with several sub-metered distribution boards scattered
throughout. The three phase supply continued to all these boards and lent itself perfectly to the retro fit PV array
proposed.
PROPOSAL ACCEPTED
The office based team swing immediately into action. Planning applications, G59 applications and an Energy
Performance certificate are standard requirement of the project. These are made along with the instruction of
Charted Structural Surveyor, Access Contractor and Health and Safety Assessor. These reports are received and
findings reviewed. These are then discussed with the client and fixes and alternatives agreed.
3. THE EPC ARRIVES
It’s not good news. The boiler and main source of heating is coal fired. This fact alone means the property will never
reach the required D band needed to qualify for the top rate of financial return without spending in the region of ten
thousand pounds. We adjust the figures to compensate analysed the costing and maintain the overall return on
investment would be almost identical if we scaled down the installation to just 12 kW. We chose the north roof as
access, safe working and electrical connection are considerably more cost effective.
With PV Installed Without PV Installed
SOME QUICK MATHS, IT STILL MAKES SENSE .
4. STRUCTURE
On this occasion the roof needed significant structural work. The calculations are made and the correct methods
employed to ensure this will never become an issue. Over 120 lm of timber along with heavy gauge nuts, bolts, and
washers are used to pin the roof fabric together following the structural reports instruction to the letter.
5. REMEDIAL WORKS
King trusses, perlins and rafters not strong enough?
We strengthen and brace the entire roof structure. Available roof space will allow a 12kW array to be installed on
each of the two main south facing roofs. The total weight of each array is well over a ton.
f
6. ELECTRICAL DESIGN
Main three phase cabling within requires no upgrade. Arrays can be fed directly into sub-distribution boards within 3
meters of the loft mounted inverters.
Each array is separately metered ensuring the most accurate production figures are available. Use of two
independent GSM modem units means this information is available at the touch of a button and in real time. All this
adds up to minimal voltage drop losses and an excellent efficiency for the client and the environment. Our
specification included the market leading SMA Tri-power TL Inverters. Two units were required as the arrays were on
opposite edges of the site.
The electrical drawings and calculations are completed and distributed to the relevant network connection authority
for consideration.
FINE TUNING
We produce 3D animations of the suns path over the site. This allows our engineers to select the best possible
module configuration. All shading issues are overcome to allow optimum operation. These calculations are checked
and double checked by our electrical engineers.
7. PLANNING APPLICATION ACCEPTED
We get the go ahead from the local authority.
DISTRICT NETWORK OPERATOR APPROVES CONNECTION
At long last we can proceed to site.
8. ESTABLISH SITE AND ERECT SUITABLE ACCESS
The fun part starts and our highly skilled installation crews arrive on site. Our scaffolder is on site the same day. An
exclusion zone is created beneath the work area and maintained throughout the installation. Notices are placed and
safety briefings given. The premises general manager is briefed on the schedule of works and works with us to
ensure a safe working site at all times.
Measurements are checked and the installation begins.
9. THE INVERTER
We position the inverter in the centre of the loft directly above the distribution board. A dwarf support wall is
chosen to mount the inverter. The existing loft hatch is too small to accommodate the large unit. It’s stripped out
and reinstated with a larger diameter hatch to allow future removal of the unit if required.
DC isolation switches are fitted to the reverse of the wall and channelled through to feed the inverter. Once inverted
the AC power then runs back through a separate channel to the main isolation switch. Everything is labelled and is
easily identified. The new loft hatch is made and fitted by our joiner’s onsite.
10. THE ROOF
Known as “pigs” in the solar industry, the reputation of these roof tiles is well known. Normal Rosemary tiles are
difficult to work with but the tiles on this roof were handmade, much larger than the modern Rosemary and almost
impossible to match.
Repairs were made to ensure roof integrity beneath the array; we give a water tight guarantee on all our projects.
11. THE ARRAY
We install 48 modules in landscape orientation. This maximises the potential of the roof space and array. Each row is
a single string of 12 making any future string diagnostic issues straight forward.
Anchors are set at the very edge of the array giving complete stability during heavy winds and periods of prolonged
winter weather. We test every module as it comes up on the roof and check this against the factory flash tests.
12. COMMISSION
The most important part of the installation is the testing of the entire electrical system. We label up all distribution
boards, isolators, wiring runs, MCBs and meter positions. We test all the existing hard wiring within the building
before connecting our installation.
Each string is tested and checked before connection into the inverter. All AC testing and earthing arrangements are
double checked, tested and recorded as needed for the installation certificate and also to satisfy the DNO’s
requirements. On this occasion a representative from BRE attends site on behalf of the client and inspects the
works.
13. HANDOVER
Having fulfilled our obligations and satisfied the inspection the site is cleared and handed back. All paperwork is
completed and handed over in the operation and maintenance manual. Wiring schematics are finalised and
published. All relevant authorities are made aware of the installation as prescribed in engineering recommendation
G59-1.
14. MONITORING AND MAINTENANCE
DAS solar will monitor and maintain this installation for the next 25 years. The Estler A1100 GSM meter gives us
instant access to array performance in real time. The system is monitored remotely and can be accessed online by
both ourselves and the client. The data is recorded and assessed on a daily basis to maintain the highest possible
yield and operational performance. All components are tested periodically and by our skilled electrical engineers
ensuring optimum production. We recommend cleaning the modules, as a minimum, once a year and is part of our
inspection.
This 12kW system will exceed our expectations by a minimum of 20% paying back the initial £22,000 investment
fivefold and continue to produce clean renewable electricity for the next 40 years.
It will produce over 300,000 kilowatt hours of sustainable electricity saving over £££££££tons of co2.
