Does this make sense if the surface area will be so neglegible anyway? I feel like the ~6m² you can fit onto the side of a balcony is nothing compared to a whole field/flat roof covered with them...
Well let's do some back of the envelope math.
Conservative estimate: 6m^2 about 6000w of sunlight x 20% panel efficiency x 4hrs/day = 4800wh or 9.5 hrs at max 500w inverter output.
Liberal estimate: 6m^2 about 7200w of sunlight x 25% panel efficiency x 5hrs/day = 9000wh or 18 hrs at max 500w inverter output.
I think this would be worth it for an apartment dweller who doesn't have access to the roof or a whole field. And producing the power when and where it's used reduces transmission costs.
6 to 9kWh is a generous amount to run a small home on
