Photovoltaics for you

Prices from £10,000 depending on size and your specification

To benefit from the feed in tariff you need to generate below 4 kw/h. In practice this means that the array of cells you install will produce around 3.6 kw peak. (This is the amount produced on a bright sunny day). In practice you will also generate some electricity on cloudy or dull days, though clearly not as much.

The location of your photovoltaic array will determine their efficiency, and should ideally be placed on a south facing roof and angled at about 30 degree from the horizontal to receive the maximum amount of sunlight. Nevertheless you can put Photovoltaics on an east or west roof and still generate very acceptable amounts of electricity. If you are concerned over the appearance of an array on a south roof or suffer significant shade on that roof, consider locating it on a more acceptable elevation, it will still be profitable.

Photovoltaics (PVs) are arrays of cells containing a solar photovoltaic material that convert solar radiation into direct current electricity.

Due to the growing demand for renewable energy sources, the manufacture of solar cells and photovoltaic arrays has advanced dramatically in recent years. Photovoltaic production has been doubling every 2 years, increasing by an average of 48 percent each year since 2002, making it the world’s fastest-growing energy technology. As production increases the economies of scale make it more economical for domestic use.

Driven by advances in technology and increases in manufacturing scale and sophistication, the cost of photovoltaics has declined steadily since the first solar cells were manufactured. Net metering and financial incentives, such as preferential feed-in tariffs for solar-generated electricity, have supported solar PV installations in many countries. You can now benefit from the technology as the subsidised feed in tariff
