It straight up doesn't make financial sense unless there are massive subsidies. I live in the Desert Southwest where we have 300+ days of sunshine a year. The Industrial Commision has been "compelled" to lower the rates of energy going back into the system. That is, we pay 08-14 cents a kWh with some BS pricing schedules that need a Gantt expert to decode... WHILE we get paid somewhere between 2-5 cents a kWh.
Solar doesn't make sense for me in other ways too... when I average my electricity usage over the year, it is around $98 per month for a family of 4, 2300 sqft home, in Arizona. If I go with solar city my bill would be $120 and I would be in a lease for 20 years. Nah...
Forget about buying the equipment myself as well due to the reasons above. The time that would be required to recoup the "investment" just isn't worth the hassle.
