First, we have to choose between an active and a passive solar water heater system. Then, we have to select the type of collector for our solar water heater. It is also important to consider the right size of the pipe line.
A solar pool heater can reduce heating costs significantly. In many climates, solar pool heating is the most cost-effective use of solar energy. As swimming pools are used most when it´s warm and the sun is shining, solar heating is an ideal application.
Solar cell efficiency tells us the amount of solar insolation that is converted into electricity. It usually lies between 12.5 and 15%. In laboratories, scientists are working on solar cell efficiency constantly.
When installing a Solar Energy System for your home you can claim up to 30% of the cost as a solar tax credit. This includes both equipment and installation. This incentive used to have a cap of $2000, but today the credit has no upper limit.
