SOLAR ENERGY

Page 3: Solar power

The earth receives 174 pet watts (pw) of incoming solar energy radiation.

Approximately 30% is reflected back to space

Page 4: Solar power

• Earth's land surface, oceans and atmosphere absorb solar radiation, and this raises their temperature.

Page 5: Solar power

The total solar energy absorbed by Earth's atmosphere, oceans and land masses in one hour is more than the

world used in one year.

Solar Panels are fitted to your roof collecting energy from the sun. This is then turned into heat and collected via a manifold that sits above the evacuated tubes. It is then piped into the hot water system where it joins the heat produced by your standard domestic boiler (or biomass boiler). An electronic controller constantly compares the temperature of the solar panels with the temperature of the water in the cylinder. On a sunny days the energy from the sun can provide all an average house's daily hot water. On cloudy days the boiler will have to be used as a backup if necessary to bring up the temperature.

Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight.

. Passive solar techniques include selecting materials with favourable

thermal properties, designing spaces that naturally circulate air, and

referencing the position of a building to the Sun.

Average pricing information divides in three pricing categories: those buying small quantities, mid-range buyers, and large quantity buyers.

In the real world prices depend a great deal on local weather conditions.
