So, we ended up having photovoltaic panels installed. Not to resell as primary objective, but to use it ourself. State subsidies our corner of the world are quite high, why not? It’s a good time of the year to start producing, although our roof is not the perfect orientation, we still manage to produce about 3 times what we consume per day. We’re getting paid less than peanuts what we inject ( because of subsidies) but we know somebody is using it and it came from our roof, not some “plant”. Silly but makes me feel better
