Nowadays more and more home solar energy systems (residential solar power systems) are used in our life. Although solar energy is green and eco-friendly, there are still some questions before applying these systems.
What do I want this home solar energy system to do?
Will the home solar power system you build or have installed act as a backup power source only?
Or do you expect to be able to use your home solar energy system to meet all of your energy needs, which include the home heating, hot water, lighting and the running of all your appliances?
