I installed solar in July, my last bill reduced by half and really interested in seeing the next bill.
I work from home, pool cleaner, dishwasher, washing machine now run in daytime. The the excess we do not use is sold back to the grid only 16 bucks last quarter!
System will pay for itself in under three years.
I also installed in June this year. First bill was $285 less than it would have been without solar. I paid $166. My bill for the same time the year before was $560.
We run our pool, dishwasher and washing machine at night. Mostly I did this anyway (except the pool).
If the government stops paying us the tariff we signed on for (which would not surprise me - non-core promises etc) then we will not repay the cost in ten years as estimated, but will still save money on power as time goes by.
