Solar photovoltaic (PV) panels and roof tiles generate electricity using the energy from the sun. PV panels produce energy from daylight, not direct sunlight, so they still produce energy on cloudy or overcast days. The electrical energy produced is either used directly in the home, or sold back to your electricity supplier. In the night electricity from the grid is supplied in the normal way.

The Sanyo HIT and Sunpower SPR photovoltaic panels are among the best available today made up of highly efficient cells that generate electricity even on cloudy days.
As well as being very clean, solar power allows you to generate electricity without leaving harmful waste products that build up to become a problem for us and future generations. Solar power is therefore a proven, reliable and very safe way of producing electricity

SANYO HIT solar cells are hybrids, made of thin mono crystal silicon surrounded by ultra-thin amorphous silicon layers. As temperatures rise, SANYO HIT solar panels produce more electricity (kWh) than conventional crystalline silicon solar panels at the same temperature. HIT solar panels have a black anodized aluminum frame, come pre-equipped with a touch-safe and electrically-safe junction box, lead wires, and plug-n-play connectors.
SANYO HIT solar panels are 100% emission free, have no moving parts and produce no noise. The panels are manufactured to UL 1703 safety standards and resist wind, fire, and hail. Anti-reflective coatings maximize sunlight absorption. The small size of the panels helps to save space and achieve maximum power within a limited amount of roof space. The panels weigh less than 31 pounds. A unique frame helps installers save space, installation time, and money for structure support materials.

A solar inverter is a type of electrical converter that is made to change the direct current (DC) electricity from a photovoltaic array into alternating current (AC) for use with home appliances and possibly a utility grid.
Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during power cuts.
A grid-tie inverter, is an electrical device that allows solar power users to complement their grid power with solar power.
It works by regulating the amount of voltage and current that is received from the DC solar panels and converting this into AC. A grid-tie inverter ensures that the power supplied will be in phase with the grid power.
This allows individuals with surplus power to sell the power back to the utility. This is sometimes called "spinning the meter backwards" as that is what literally happens

The export meter and grid connection
|

|
|
|
|
The export meter (with the blue button) measures the amount of electricity the panels produce, Any electricity that you consume from your PV installation replaces electricity that you would otherwise have to buy.
If your system is under 5kWp, most of the utility companies will offer you an export tariff.

ROCs (Renewable Obligation Certificates) are awarded by Ofgem for renewably generated electricity. They are awarded for the total number of MWh (1000 units) of electricity generated by the system (not just electricity exported), with rounding to the nearest MWh.
From April 2009, PV systems will be awarded 2 ROCs per MWh.
