Curious why you'd put solar panels on the ground. Maybe there was no solar-viable roof nearby? I ask because I've seen more people lately put them on the ground just to make them easier to clean and maintain. Can't say I agree with that mentality: covering green grass with black solar panels instead of using already allocated build areas. If everyone did that, the albedo may end up worse for global warming than not having them: our planet is going to end up looking "black" from space.

Having grass is pretty bad for the environment with all the displacement of native plants and the all the mowing.
I don't know about the OP but I have my array on the ground because my house roof is shaded at all times and my garage slopes the wrong way. Not to mention it's much easy to clean the snow off when ground mounted vs on a 12 tall roof at the lowest point.

I've seen some of the massive solar farms where they've cleared out trees to replace nature with black panels. Not sure it's worth the footprint in the long run and I think we should be using existing structures and claimed areas! And I've got news for you: most ground mounted solar systems will end up needing more maintenance (mowing and weeding around them) than driving a mower over the grass patch that used to be there for 20 seconds.

Are you grid-connected? If so, how do you route power among vehicle, grid, & home? I'd be interested in hearing more details.
We are still connected to the grid, kind of. We have a three position manual knife switch, solar - off - grid. Solar runs our entire house. If the batteries get depleted and there is not enough sun I can either a) switch over to grid power or b) let the propane powered generator come on and charge the batteries. I much prefer option A as I seldom use enough from the grid to get more than the minimum monthly charge. This August has been the worst month in the over one year we've had the system installed. My neighbors have electric bills between $300 and $600, mine was $72.

I only charge the car during the day when I have direct sun on the panels. We're retired so that causes us no hardship.

The biggest reason is when we built the house we didn't plan on solar power. We don't have a south facing roof. You want your solar panels facing south. We live on 40 acres. I can assure you the space taken up by the solar panels is a speck compared to all the green around.

Ahhhh, but what about when it's time to replace your roof? You mention mowing and weeding around them, you're right, stuff still grows under them.

Bought it off the lot just over a week ago. Had to drive 200 miles to get it, but so far I'd say it was worth it. The dealer has a couple of certified pre-owned Bolts if anyone is looking for one. A 2020 EV LT and a 2022 EUV LT.

Nice, but what are all those spots on the front? I'm thinking a paint protection film is definitely something I'm going to have to look into.

Have you thought about documenting your experience with the solar panels? One of the biggest annoyances I have from people that hate renewable is how they claim that solar power is unreliable, and my first thought is "We LITERALLY set our clocks based on the sun". It would be nice to see someone with real world experience out there demonstrating what I learned a long time ago via a certain movie about a goofy looking little red headed girl..

Solar inverters usually have apps that allow you to control your system. Some have dedicated car charging ports in the inverter, I think solar edge has one.
My solar system is grid tied and I send power back to the grid and get a credit.
I sized the system to eventually charge evs. I have battery backup for power outages that I get a few times a year instead of putting in a generator. Hoping to one day be able to integrate a ev car into the system one day before I retire.
I put 38 kw in my bolt over the weekend just from solar and run my house. Solar is a lifestyle. You do your heavy use when the sun is out. If not I use the grid. But it's not much until I fire up my geothermal. Lol
I run the geothermal to cool the house but it's summer and I've got plenty. In Northern Michigan you don't cool much.
My house is totally electric, no gas or fuel because we don't have access to natural gas and propane will break you.
When charging my bolt I use a JuiceBox evse and I can control the amps in single digits to match the solar output and if s cloud comes over my battery backup will make up the power til the cloud goes away and I can set the JuiceBox to allow the home battery to charge and charge my car and run the house.

I did the same... 8.2KW on the ground but I'm on 5 acres. Being on the ground let me set the direction and angle to be the absolute max output I could get (average) in my longitude and latitude. I would have gone bigger if I'd known that my electric company would revoke net billing shortly after the install... :mad:
