Anyone have solar panels on their home?
Just got a basic 2-panel "Balkonkraftwerk" (lit. "Balcony powerplant") installed on our toolshed roof a month or so back, so really too small / too late in the year/ too soon to see any noticeable difference in grid-electricity consumption so far. But the guy who did the installation already upsold us to full-roof coverage, which he'll begin installing next month, once we've got the financing lined up.
We're under no illusions that we're likely to reach break-even on this setup anytime soon, but that's not really the point of the exercise -- which is to have this up and running before our gas-fired boiler (water + central heating) reaches the end of its useful life, becomes economically non-viable due to price-hikes, and/or its continued usage gets legislated against. Our house was a new-build when we moved in 17 years ago, so the boiler may already be on borrowed time.
We're expecting that we'll need to replace it with a heat-pump -- which means our electricity usage will go up, especially over the winter when the solar water-heater isn't as useful (we installed that kit shortly after we moved in, and it has substantially reduced our gas/ electricity bills, relative to the German average for a 4-person household).
Just FTR, we buy our electricity from a distributor which (claims it) sources its watts from (allegedly) renewable sources, but I'm not 100% sure what the legal standards are, or what's hiding in the fine print (e.g. just because nuclear doesn't release CO2 from the actual power-generation, doesn't make it eco-friendly, no matter how much power-companies would like to greenwash it...). So generating at least some of our own power seems like a good idea, regardless.
