Third extended heat wave within 6 weeks.
The previous one exceeded 40°C, and the buildings not yet had time to completely cool down from that one before the third wave hit.
I was considering putting up a tent in my garden myself, but as I own a ground floor flat, the indoor temperatures did, with the help of some additional cooling measures, thankfully not exceeded 27°C.
that solar is plug in balcony solar, meaning it probably doesn’t have a battery, so only works when the rest of the power grid is working. if they are in a power outage it isn’t providing power. that’s for safety reasons as they don’t want these balcony solar units to back feed into the larger power grid that would cause power companies from working on power lines
So, you as the owner get the cost, almost no money for the energy but also no off-the-grid security? Do i see a pattern?
It mainly covers your base consumption.
Profit you make is the savings you have because you have to purchase less electric energy from your provider.
Typically pay for themselves within 3-4years for such an installation on south facing balcony in my region.
The rest of the 20years of its lifetime is just free money after that.
I have a two panel installation, saving me ~120€ per year.
