Panels $116 for two, I bought four
For the wiring you need to connect the panels together $36 for three pairs (if you're doing them in parallel like I am, you can skip this step if you design your setup in series and just connect the panels to each other directly)
You'll need an inverter to plug stuff into $41
A battery if you want to save and use electricity at night $190
A controller $12 I bought the cheapest one I could find
The rack $120 I could have made this out of wood for cheaper
Battery to Controller cable $10
Battery to Inverter cable $12
Panels to Controller cable $17
so $640 plus shipping if you buy from Amazon, but a lot of these things can be found in home improvement stores too so maybe shopping around can save you some cash.
but does it connect to your house or.. you just have to plug things into this?
Would have to plug things into the inverter. There are microinverters that basically allow you to plug panels into your house though (by syncing with the frequency of the power you’re getting from the grid). They’re much more expensive than this, and I think you’re not supposed to use those in the US unless you go through some sort of approval process. It’s becoming more popular in Germany for people to use microinverters for solar panels on stuff like apartment balconies.
I see.. well its nice to have free power anyway
