Congratulations to all the newly installed solar owners. You made a smart move. Soon the masses will wise up, and the stampede will begin. My system has been producing for over 6 years. Even though it was much more expensive than today's prices, it has been paying off since day 1.
My 20 year old 9kw diesel generator provides whole house power when the grid goes down, at a fuel cost of $1/hour. We live at the end of the grid, in the boonies, so we are usually the last to be restored after storms or outages, Nonetheless, the generator has only had about 100 hours of run time over those 6 years.
I will soon add a Tesla Power Wall which will eliminate much of that run time in the future; I will only have to activate the generator after several hours of an extended outage. And, the solar system will continue to operate if the sun is shining. Both the solar system and the generator will recharge the Power Wall.
Unless you live where power is extremely cheap (less than $0.10/kwh) or where solar is impractical, or you plan to move in the near future, you should not remain on the sidelines!
