The state California (37.0000° N 120.0000° W) is located on the western side of United States of America. This state receives the good amount of the solar radiations averaging 5.73 KWHr/m²/day, making it a favorable place for generating electricity from solar power.
I will discuss the financial feasibility of solar by calculating the break-even cost of the 5KW (without battery) residential solar power system in the state.
Let us look at the solar radiations falling in this region throughout the year:
Few things about the state
If you notice the table above, the actual cost of the 5 KW solar in California is around $ 17,500 without any tax credits or incentives. This cost is well below the breakeven cost of $ 22,365 as calculated by me on the basis of the financial parameters given. The actual return offered by the system will be 5% per year as compared to the breakeven return of 2.2%.
I can very easily say that the residential solar power system in the state California is FEASIBLE.
