Though the initial investment for a solar heating and lighting system can be high, the home owner can save a lot of money on electricity bills over a period of time. The home owner will also not have to rely on expensive grid power. Hence a home which has a running solar system installed will have a higher home value compared to a home which relies on conventional grid power sources. Water heating and cooling systems consume most of the power in a house.
However it remains difficult to find a reliable supplier of solar heating and lighting system. Finding a supplier of a solar powerbank for laptops is also difficult.
