How solar panels works to your home

  1. 1. How does solar work? Solar Panel installers
  2. 2. Solar Photovoltaic (PV) panels are generally fitted on the roof in a northerly direction and at an angle to maximize the amount of sunlight that hits the panels. Solar PV panels on the roofs of homes and businesses generate clean electricity by converting the energy in sunlight. This conversion takes place within modules of specially fabricated materials that make up the solar panels. It is a relatively simple process that requires no moving parts. In most cases solar panels are connected to the mains power supply through a device called an inverter. Solar panels are different to solar hot water systems, which are also mounted on household rooftops but use the heat from the sun to provide hot water for household uses. The technology to convert sunlight into electricity was developed in the 19th century, but it was only in the second half of the 20th century that development accelerated behind the need to provide reliable supplies of electricity in remote locations – from satellites in space to outback Australia. Solar panels have been installed on the rooftops of houses and other buildings in Australia since the 1970s. Currently there are more than 100,000 solar panel systems safely and reliably delivering clean electricity across Australia. Solar Panel Installers 2
  3. 3. How does the inverter work? Most suburban homes in Australia are connected to the electricity grid, which uses alternating current electricity (AC). But the electricity generated by solar panels is direct current (DC). That means grid-connected (GC) solar PV systems need an inverter to transform the DC electricity into AC electricity suitable for ordinary household needs. Houses with solar systems use solar power first before sourcing electricity from the grid. Solar photovoltaic – how it works Solar Photovoltaic (PV) panels on the roofs of homes and businesses capture the sun's energy to generate electricity cleanly and quietly. Light energy is converted directly into electricity by transferring sunlight photon energy into electrical energy. This conversion takes place within cells of specially fabricated semiconductor crystals. While it might be true that solar cannot generate electricity all the time, it does generate electricity when it is needed most – during the day and on hot sunny days when electricity demand is at its peak driven by air-conditioners. Importantly, electricity is generated at the point of demand - where people live and work which means there is no need to transfer the energy long distances across expensive infrastructure.

  4. 4. Greenhouse gas savings Solar power is a zero-emission electricity source. One-megawatt hour of solar-derived electricity avoids approximately one tone of CO2. In Australia Solar PV power is installed on almost 200,000 rooftops across Australia. At the end of September 2010 we had over 300 megawatts of solar PV capacity installed nationwide - an increase of almost 10 times in less than two years. The majority of solar PV installations are grid-connected systems. However solar PV also has a long history of supplying reliable 'off grid' power to remote and regional Australian communities. With the right federal policy in place providing incentives for take-up, we can ensure continued growth of Australia's solar PV industry. The Clean Energy Council is actively advocating for a gross metering feed in tariff that will be set high enough and for long enough to encourage increased take-up of the technology nationwide. Potential As one of the sunniest continents in the world, there is massive potential for solar PV to make a significant contribution to electricity generation in Australia. Couple this unrivalled resource with a multitude of open spaces, and there is no reason why Australia cannot have large scale installations generating many megawatts of electricity for sale into the grid.

  5. 5. Solar Panel EC SOLAR EC SOLAR is one of the leading partially vertically integrated manufacturers of crystalline solar cells and solar modules. EC SOLAR is a subsidiary of Wuxi Saijing Group, which was founded in 1980s and achieves great success in copper business and now provides powerful support for the renewable business. With the area of 200,000m², located in Yixing, China, operates one of the most modern production facilities, each day more than 60,000 cells and 3,000 high-performance modules come off the production line. Currently, more than 1000 employees are working in our factory, including 300 experienced researchers and engineers. The fully integrated production line and advanced producing and testing equipment ensure that the production from solar cells to modules is under the strict quality and cost control. We try our best to achieve 100% customer satisfaction. Solar Panel Installers 5
  6. 6. From the beginning, EC SOLAR has been striving to provide high-quality modules for families, factories and public utilities all over the world. Our products enjoy a ready market in many countries and areas, including Europe, America, Australia, Africa and Southeast Asia. EC SOLAR is looking forward to accelerating renewable energy development and making a better tomorrow for enjoying life under the sun. EC SOLAR manufactures solar cells from silicon wafers and utilizes crystalline silicon solar cell technology to convert sunlight into electricity through a process known as the photovoltaic effect. EC SOLAR manufactures solar modules with one of the most comprehensive product portfolio in the industry, polycrystalline or monocrystalline, framed or laminated, extra large modules or normal sizes. EC SOLAR delivers 'high performance solar modules' Europe, America, Asia, and all the way to after-sale service. to various countries in EC SOLAR has also joined 'PC Cycle' for recycling of modules after its lifetime and implementing its thoroughly green company philosophy.

  7. 7. Q-CELLS AUSTRALIA WHY Q-CELLS AUSTRALIA? Local Support. German Engineering. Guaranteed Quality. Q.CELLS Australia is a vibrant company that strives to continuously provide not only the best modules, but also the best service to our customers. We do go the extra mile and consider ourselves a partner rather than a mere module supplier. We are here to help you choose the right system for you. If you are after something a bit different, we are here to work it out for you – regardless of system size or geographic location. We monitor over 30 testing sites throughout Australia, including two of our systems at the Desert Knowledge Center in Alice Springs. Q.CELLS was founded in 1999 in Thalheim, Germany. Within a few years we evolved into one of the biggest solar cells producers globally. Instead of only supplying some of the best panel producers with our high quality solar cells, we then decided to use our know-how and expertise and to start producing solar panels ourselves. We know that only high quality modules integrated with superior technologies can form the basis for reliable energy output. Solar Panel Installers 7
