IMO, permitting, electrical work, installation is expensive for grid-tie solar, which makes inexpensive solar solutions not possible. (Also, requiring a microinverter for every panel)
I have a off-grid lot with a ~1.5kw of solar, which cost me around 2k USD (with ~5kw battery), self-installed. I'm planning to install something similar on my home. The electrical permitting should be easy as I won't be hooking up to grid (I plan on running my mini split/heat pump off of it).
- kiliantics 4y agoHow long ago was this? I just bought batteries for solar and you can't get cheaper than around $800 per kWh without building your own battery. And panels are rarely much less than $1/Watt new so I can't see how you'd build such a system for much less than $4-5k and that's before mounting costs.
- turtlebits 4y agoI built my own battery pack last year for $900 - 32x 55ah Lifepo and BMS, but you get prebuilt w/ warranty for ~$280/kWH (current price). See EG4 or SOK 48v batteries. When I last looked in 2020, you could buy a pallet of new solar for ~ $0.37/watt. Looks like prices now are around $0.50-$0.65 /watt
