Guess it’s about time to post some update to my photovoltaic roof thingy. The generator is now running for 6 months, without any downtime, and produced ~700 kWh during that period. Right now, that’s about 10 percent below the estimated yield (based on a simulation, which in turn is based on the mean from 20 years of local weather recordings), and has saved the athmosphere around 88 kg of CO2 exhaust (well, not really. First of all, the generator has to earn the energy it has used up for producing and mounting it. This might take some years).

Currently, with the May providing a cloudless sky one day after the other, we’re reaping 20 to 25 kWh per day (could be even more, if it wasn’t so damn hot for the season – thermal effects in the panels now cancel even more of the electrons).

All in all: feels really good.

Operational, and in the sun
