Solar wiring and connection issues: a hidden performance killer in London
Loose connectors, corroded terminals, and damaged wiring cause resistive losses that silently drain your system's output. Unlike other faults, wiring issues can also be a fire risk. Here's what to watch for and why you should never attempt DIY wiring repairs.
London has a maritime climate with 3.8 peak sun hoursper day. The UK's cooler temperatures benefit panel efficiency but shorter daylight hours affect annual output.
