A $10,000 add on really isn’t much but it’s probably not that big of a system either. It will pay for itself quickly.



I dont see how this is true. Energy storage capabilities arent great and how long will these panels even last? What's the long term cost over 30 years? Includes panel maintenance, battery replacement cost etc.

Y'all have to stop thinking about this like it's in Louisiana. Out west, when it is sunny, your panels feed power to your house AND the power grid. Your power meter will run backwards. So, at night you will be using public power, but the credit you built up during the day covers that cost.

No batteries or storage unless you want to be off the grid.

Last time I priced it out, it was $15,000 for a new install.

As already mentioned you don’t need a battery in CA. Tesla offers 14 kWh storage so you’re wrong when you say “aren’t great” but it does cost $10,000+ just for a Tesla install. Anyway, $10,000 probably buys about 10-15 panels or so with it happening during construction. That should be around $100 worth of energy and maybe more depending on electric rates there. Less than 10 year break even without calculating tax credits.

What panel maintenance are you talking about? They have a 25 year warranty and just sit there. The inverters could have an issue but many of those have 25 year warranties as well so maybe you just pay $500 for labor in 10-15 years for that.
