These days green energy is a hot item. Having a pv installation is almost a must. Since i live in an apartment i don't have a roof that i can use for solar panels. The only possible spot is above my balcony where it is open. Here i can mount two solar panels and yet have space enough to place a ladder to get on the roof to mount them and for maintenance.

I already had a solar panel since 10 years, with a cheap chinese inverter. But that doesn't yield much due to the poor efficiency of the inverter. These days the inverters are much more efficient, they start producing right after sunrise, in summer even before.

To realize this idea i designed a steel shelf support, long enough to carry my solar panels. A friend who has access to a metal workshop could weld them together.
