How Long Do You Plan to Stay in Your Current Home?
It will probably take a number of years to recoup in energy savings the cost of your solar system. If you’re thinking about moving within the next five years, you should carefully evaluate whether installing a solar energy system is a good idea right now.
How Much is Electricity Cost to you?
Determine how much electricity you use each year, and how much you pay for each Kilowatt-hour (KWh) from your current electricity provider. Also find out the break even point, when the money you save every month will equal the cost of your system.
determine Your Roof Point?
Make sure your roof is oriented toward the southern (including southwestern and southeastern) sky and isn’t shaded by trees or other obstructions that could limit the energy generating capacity of your Solar system.
