I’m looking at making use of a 2.5mx7m flat roof. Obviously the hive request more time investment but I’m willing to learn
Putting a hive in a city is a bad idea. Domestic bees, which are more resistant because they are fed by humans, eat the food of wild bees, and accelerate their disappearance.
Do the solar panels and let native pollinator friendly plants to grow around it.
Install solar panels and plant local flowers (drought resistant in drought prone areas).
Are 4 solar panels enough?
No but that’s all I can fit there
4 Solar Panels are plenty, I have 2 and on sunny days you get much more than you can consume. I would recommend just getting 2 aswell (I got 870Watt peak in total) because everything else would require either some form of battery or would involve giving the energy into the power grid. Also in Germany there is a 800W limit for easier registration aswell.
Neither of them will have any significant impact we are all already fucked.
