That system should have run him 9k


I don't know any exact numbers, but it was something along those lines. The panels themselves, plus the batteries (there are 12 I think) and then the console or whatever. That thing alone was a pretty penny from what I understand. He installed it all himself though.

Building a new home in Washington state with a 12kw solar system. Combined with passive solar construction, geothermal heat pump, etc. the house is designed to be net zero (including charging for electric car). We are designing the home to minimize environmental footprint and withstand somewhat frequent power outages (rural location) rather than return on investment but estimated payback is 7 yrs after fed and state tax benefits.

They look like sails just waiting on some hurricane wind.

Which is why it voids policies down here and you are unlikely to get it added to a current policy.

We just went through this in our neighborhood. Our hoa has a written restriction about solar panels. The resident lawyered up and there's apparently a state law that was passed in Louisiana that doesn't allow hoa regulations on solar panels anymore.

Good for your neighbor. I don't know about every state, but Hawaii and Louisiana have laws that tell the HOAs to go frick themselves and that you can collect the free sun on top of your own roof.

As far as payback timeframes, it's funny listening to people in these threads.

FTR, I don't have them on my crib, but wouldn't mind them. I question those who say, "they don't look good on a roof." Buddy, if you're someone who finds roof aesthetically pleasing to the point they can be considered ugly by PV panels, you need to find a better hobby.



You know what looks uglier? An electric bill every month for the rest of your life when there are ways to "zero out" or limit your bill a good bit. "Nah, I'd rather pay for energy than produce my own!"

I made this spreadsheet a while back when I was looking into solar panels:

LINK

I've hightlighted the cells that require input.

Cell B1: Input your average annual electricity usage (in KWH)
Cell B2: Input how much you spent on electricity in that 1 year period
B5: I have a 3% inflation rate per year. Could be 2, could be 4, who knows.
E1: Average sun hours per day. Use the link to the right side of this to determine this value.
E2: Total output of the solar panel system you're looking at. Locally, companies are advertising 7kw systems for the $25,000.

Off to the right, it shows how munch you would normally spend on electricity over the next 30 years without solar panels, next column shows how much money you would save with the inputted Solar System per year, and last column shows what your new electricity cost would be with solar panels (assuming you don't have a 100% solar system)
