Cost $4 $484 $296 $635 $154 $172 $1,745 Gas Cost AASE at your location (value from map times 365) = 1,825 kwhr/m2 AASPO at your location = (AASE divided by 8) = 228.125 kwhr/m2 Size of solar panel needed for your location = Total Kwhr (from table) divided by AASPO = 64.28 m2 Average cost of 1-m2 commercial solar panel = $800 / m2 Estimated cost of home solar system = Size of solar panel x average cost = $51,424 1) The average solar panel system should last about 25-30 years before it needs to be replaced. If you were to keep paying the same cost for electricity that you do now, how does the total cost of a solar system compare to what you will pay over that time span? 2) As oil prices continue to increase, it is expected that all energy costs will go up. If this happens, you can expect to pay more for electricity in the future. If the cost were to double over the next decade, how would this affect your answer to question 1
