I read on another forum that Tesla Powerwalls cannot be charged from a generator. Is there a way around this? Thanks.

I have been offered a new-in-box Sol Ark 12K - P inverter for $6,000. No shipping since I can drive to pick up. Wuddaya think? Good unit? Good price? Do you know of a better option? Thanks!

I’m on my third cruising sailboat, all off-grid cruising capable. About 10,000 nm but who’s counting? If your goal is just keep the beer cold, shut off the freezer - dead load for no gain, and freezers by definition use more energy. Figure your refrig at about 70% cycle-on time. As you...

Thanks for that excellent reply! The house has a 11kw propane generator and is on the grid now. Because the house is in the tropical sun, it gets a lot of solar energy. My first thought is to make awnings with solar panels so that I get the comfort benefit of the shade as well as the power...

Thanks. I’m looking for design ideas for 6kw-10kw. If you can “name that forum” I’d be grateful.

I’m looking at new Trina’s for $.45/W. Having spares implies removing old, bad panels and installing new ones. I once was a younger man.

Where is “Will’s site”?

Nice price! Living on an island, it seems wise for me to buy new.

First off, thanks for all the replies. I live on a sailboat (2 x 265W = 530W; 6 Group 31 AGM batteries; Midnight Sun MPPT CC) so I’m not a total newb, BUT this house is a different animal. We haven’t even closed on the house yet, but we are having household goods shipped here (USVI) from NC in...

On their website prices get as low as $.64/W, no lower. A1 Solar has a large selection at <$.60/W - Any recommendations from this selection? https://a1solarstore.com/solar-panels.html

New to the forum, I am asking for a few recommendations for hi-wattage panels with good specs, strong frames, overall good quality at a low price per watt. Any brands that I should avoid? Trina and Canadian are looking good - thoughts? An explanation of pa load ratings would be helpful, too...

“I would create Bahama-style shutters” It is unlikely that we can engineer panels like storm shutters, though on a different structure it would fit like a glove! There is the issue of whether to install end to end or side to side - more power on the same eave when side to side; less leverage...

The house we have purchased in the USVI catches a LOT of sun! Has anyone ever used solar panels to extend the roofline, like your might use awnings? They would need to be removable, or at least capable of being folded down, so that we can protect them in the event of a hurricane. Thx
