This is a list of what you need to know before you transition over to solar energy.
Does your roof support solar panels?
Is your roof sturdy and supportive? Is your roof covered in shade? Does your roof get sunlight? Solar panels are mounted with different kinds of equipment and different kinds of installation processes can be used to best harness sunlight but if there’s no sunlight your roof will not be the best place for solar panels as sunlight is necessary for harvesting energy. If your roof needs replacement you will want to do that before getting solar panels installed.
How will you connect to the energy grid?
Will you need to pay any fees to your existing utility company to get hooked into the grid after you install solar panels.
How much will you save on your energy bill if you transition over to solar?
In California, estimated savings over 20 years is $29,000. The typical American family spends about $1400 a year in electricity. Electricity costs go up about 2.2% per year. The amount of savings depends on how much you spend on your current bill.
How many square feet is your house?
A 2,000 square foot home could use a solar array of 4,000 watts. Depending on your system, you may need 12 to 18 solar panels.
