DIY Solar Installation: Genius Idea or Total Disaster?

Balcony solar or DIY solar is a mega trend sweeping across Germany's solar industry. This phenomenon caught my attention during my visit to The Smarter E in Munich, Europe’s largest renewables event. The concept is straightforward for apartment dwellers: you simply hang a few solar panels over your balcony, connect them to a small solar inverter, and plug them into a nearby power outlet. This allows you to use free solar energy to reduce your energy bills. Similar to larger installations, you can incorporate battery storage to store energy during the day and offset power drawn from the grid during expensive peak times. Advanced systems can also be paired with wireless metering to maximize self-consumption rather than exporting excess power back to the grid. These systems usually consist of 2-4 solar panels, generating around 1 to 2 kilowatts peak. One unique aspect of this concept, which may seem strange to electricians, is that you are sending power back into a power outlet. This initially suggests that the plug’s pins are live when the inverter is powered up. However, balcony solar inverters are designed to activate only when a mains voltage connection is detected, ensuring that mains voltage never appears on the exposed pins. In Germany, regulations cover this application, limiting the maximum power injected back into a socket outlet to 800 watts. Since many apartments are rented rather than owned, tenants can add solar without interfering with the building’s fixed wiring. If you decide to move, your solar PV system can be easily relocated. In the UK, these systems aren’t permitted due to regulatory issues related to connecting parallel generation back to the electricity grid. Do you think Germany's move to make solar more accessible to consumers is smart, or is it a safety risk encouraging DIY enthusiasts to meddle with electrics? Should the UK allow this type of DIY Solar installation?
