Yes, its kinda complicated and there are lots of reasons. The solar advocacy groups fought a lot to make it so that you dont even have to ask/notify your landlord or energy provider for these <800W installations
Feeding in a lot of power (and especially quickly switching it on and off) can create grid instability (because the electricity grid is stupid and designed for large centralized powerplants)
At some point (really big commercial installations) you are even required to install a remote disconnect system that the provider can use to turn off your installation if the grid is overloaded
You dont get the same amount of money for selling energy then buying it, which means with high power installations the provider loses money if they dont install a smart meter (meter that keeps track of how much flows out and into the grid)
With <800W installations the provider can still install a smart meter if they want, but you dont have to notify them of your installation
I hope i didnt mix something up here. Obviously read about your local laws if you install anything.
That’s neat. Someone told me about inverters you could just plug into a wall socket and have it feed appliances in the house here in Spain, but I just thought they were crazy.
In Germany, can you use the solar panels to directly feed the grow-lamps for a couple of healthy cannabis plants? Is that also permitted?
As long as you dont connect it to the grid (island mode) you can do whatever the fuck u want and go way beyond 800W. You can buy a full kit of these 800W setups (panels, cables, inverter) for like 2-300€ sometimes. The one i got says that its island capable, but its not really optimal for grow lamp use, because for that you need battery storage and the cheap ones arent capable of that. Idk how much power these lamps use, but there are relatively cheap 12V solar charger + inverter systems that use car batteries for storage.
