  • How do you install a solar power system for the whole house?

    Q:How do you install a solar power system for the whole house?

    A:

    Estimate the amount of solar panels needed to satisfy the electrical power usage of your home by dividing your average daily energy use by the amount of solar resource available to your region and multiplying that number to adjust it for the efficiency of your panel. Gather your utility bills, and by using a computer, it takes about 30 minutes to calculate the amount of solar panels you need.
