Solar Photovoltaics (PVs) are arrays of cells containing a material that converts energy from the sun into electricity that can be used to power lighting and other appliances. Due to the growing demand for renewable energy sources, the manufacture of solar panels has advanced dramatically in recent years.

PV systems can be
  Grid-tied (the electricity can be used on site and fed into the grid)
  Off grid (charge batteries)
Roughly 90% of this generating capacity consists of grid-tied electrical systems. Theses systems, once installed, need little or no maintenance. Such installations may be ground-mounted or built into the roof or walls of a building, known as Building Integrated Photovoltaics or BIPV for short.

Since Apri 2010 the government have replaced the grant scheme with a feed in tariff (FIT)

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.

Solar Thermal


Solar Thermal energy is a technology for harnessing solar energy for thermal energy (heat). Solar thermal collectors are defined as low-, medium-, or high-temperature collectors. Low temperature collectors are flat plates generally used to heat swimming pools. Medium-temperature collectors are also usually flat plates but are used for creating hot water for residential and commercial use.

Medium collectors could be used to produce approximately 50% and more of the hot water needed for residential and commercial. Solar water heating can reduce CO2 emissions by 1 ton/year (if replacing natural gas for hot water heating) or 3 ton/year (if replacing electric hot water heating).
