I recently started selling solar in AZ. It makes sense to design a system that generates the power for the peak periods (noon to 7PM) when the cost of electricity is ~$.30/kWh w/taxes and fees. For my house my last bill was $128 vs $278 last month and $312 last year. Of course your mileage may differ, but my payback period is about 5 years when you include the 30% fed tax credit and $1000 AZ credit. Solar in this area helps sell itself.
Do you see a significant rise in property taxes with the addition of the solar panels? This is partly the reason I’m hesitant to look into it.
My peak bill was $568, just last month. It cost about $2500 to run 1 unit at 76F and 1 unit at 83F for the 5 summer months. Do you think solar would pay off if I stay in this house for another 6 years? Do buyers pay more for a house with solar?
