    Balcony solar is a set of diy technologies that require no utility permissions.

    In Germany, NL, you can just plug it into socket and it works somehow.

    In us you can use powerstations and also adapters that sync draw from battery as it charges from ac in house.

    It pays for itself even with more expensive equipment, by not needed license, permission, that can lead to cheap efficient panels costing over 3$ per watt. Small systems that just offset use instead of selling back, have higher revenue offsets in high per kwh priced markets.

      This is incredibly dangerous as it will feed power into the grid even when the grid is down. You might say ‘that is great!’, yeah, well, the line technicians who cannot work on damaged cables because you are energizing them think otherwise.

      One of the reasons home solar grid-feeding systems are expensive in the US is they have extra equipment to disconnect the system from the grid if the grid goes down. Your house can still have local power, but you won’t be energizing powerlines technicians are trying to fix.

        These plugin systems shut down automatically when there’s a power outage. To make sure that they really do shut down when needed, in Belgium only plugin systems that have been approved by the network management organisation may be used. The other countries that allow these probably have similar precautions.
