Plug-in solar panels are a cheaper, simpler alternative to professionally installed panels.

Most RCDs used in the UK aren’t suitable for current flowing in both directions and so could malfunction. In the US, the set-up is different but there are similar problems. One reason why Germany has managed to move so quickly on plug-in solar panels is that by coincidence it standardised bi-directional RCDs in the 1980s. en regulated cell death.
