What factors affect how much energy solar panels can produce?

Never climb up on your roof to clean your solar panels (for obvious reasons)! Instead, you should get a soft, extendable brush that you can use from ground level - this will probably cost about £100. Alternatively, you can sit back and pay professionals to do it, who typically charge about £10 per panel.

Should you get an oversized solar panel system?

It’s possible to add more solar panels to your system later on, however it often requires additional work such as upgrading the inverter and/or rewiring the system, and you’ll also be paying for another round of scaffolding and labour. The most sensible approach from a financial perspective is to maximise your roof space the first time around.
