2 WHY SHARP SOLAR? Experience, Reliability and Innovation Half a century ago, in 1959, Sharp began their development of solar PV cells. As a manufacturer of products that consume electricity, they took the view that it was their responsibility to sustainably create electricity as well. They were pioneers in realizing the potential of solar energy and have continued to develop it ever since. From lighthouses, to space satellites to mega solar power plants, Sharp has been providing reliable solar solutions to help free the world from carbon dependency. As the world leader, nobody is able to provide a better solar solution than Sharp. Ogami Island Light House installed 1966 SHARP-SOLAR.COM The Sun: it s not yellow, it s green! Britain s future has never been brighter, because Sharp has enhanced the efficiency of solar power systems to make them viable even in cloudier climates such as ours. The important thing to bear in mind is that solar power generation depends on intensity of light, not necessarily direct sunlight. On a clear day, solar energy of about one kilowatt per square meter reaches Earth s surface. A single hour of solar energy reaching the Earth would be enough to supply the world s current energy needs for an entire year. Harnessing this energy produces no CO 2 emissions.

3 SUN RENEWABLES LtdSolar Modules: SHARP MADE IN THE UK One of Sharp s most technically advanced solar PV module manufacturing plants is located in Wrexham (north Wales); this, their first European solar PV plant, is a state-of-the-art facility, manufacturing solar PV modules since Today it assembles Sharp s latest highly advanced solar PV modules.

5 Photovoltaics: using science to unlock the power of the sun Greener homes, greener future The photovoltaic effect is the conversion of sunlight into electrical power. It is a process which involves the release of positive and negative particles as a result of the introduction of light into solar cells. The electrical circuit is produced by a grid of solar cells connected in series within the solar PV modules. The consequent physical reaction in the solar cells then generates direct current, which can be converted to alternating current, depending on requirements. As the PV modules that perform this function have no moving parts, the system requires only minimal maintenance and is silent in operation. Best of all, they generate electricity without generating any of the harmful emissions currently threatening our environment and climate. The sun delivers over 219,000 billion kilowatt hours of energy every year to the earth; over 2,500 times more than the total world population currently requires. The power to reduce your carbon footprint 1. The PV array is installed in the best location to maximise the power output, for example in a residential installation on the roof. The PV modules which make up the array are connected in series to supply a direct current. 2. This direct current is then converted to alternating current at grid rating by the inverter. Each kwp capacity installed in the UK will generate, on average, 800kWh per annum (varies depending on orientation and location). 3. This AC generated by your PV system is connected into the main distribution box for the building. 4. Here it uses the same electricity that would have been drawn from the grid. In times when you are producing more than you are using, any excess is fed back to the grid, while excess demand is topped up by drawing from the grid as usual. 5. The electricity meter will thus show the net electricity exported or imported to or from the national grid by the property.

6 Feed-in Tariff (Great Britain) Solar PV systems qualify for the government s FIT, or Clean Energy Cash Back scheme, which guarantees a minimum payment for 25 years from the energy supplier to the householder for each unit (or kwh) of electricity generated by the system, as well as a separate payment for electricity exported to the grid. The FIT is designed so that the average monthly income from your installation will be significantly greater than any monthly loan repayment, and will cover the purchase price of the system within an average of 6.5 to 9 years. Good for the environment, good for your bank account. Average Figures for a 3.76kWp PV system Energy produced: 2957 kwh % of average consumption: 83% Feed-in Tariff: 1230 Electricity saved: 177 Electricity Exported: 44 CO2 saved: 2.6 tonnes N.B. Figures based on August 2011 data. 1. Every unit of electricity you produce by a green means earns you money, whether that electricity is used or not. The FIT rate at which you join the scheme is guaranteed for 25 years, plus the tariffs are index linked to inflation (RPI-retail price indexed) and will increase in line with that. 2. In addition to the tariff paid for all the electricity you produce, any excess produced is exported to the grid and an additional tariff of 3.2p/kWh extra is paid. The Feed-in Tariff is working well in Britain. Since its introduction in April 2010, many people are now taking advantage of the guaranteed income available from producing their own solar electricity. There are three ways in which the FIT works: 3. You will greatly reduce your electricity bills by using most or all of the electricity you have produced rather than importing from the grid. The tariff a customer will receive is dependent on the type & size of installation. The tariff is banded as below.
