Get multiple prices, and let him know you are doing so!Lots of good tips thanks, made notes in me little book so I can quiz them tomorrow!
Roof orientation, and shading (even partial, as in the shadow from a soil pipe vent), can make a huge difference to the performance/payback from solar panels.
Can I get that translated into idiot English please.We use panel level optimization to stop a partially shaded panel pulling the whole string down

Thank youPV panels are connected together in a string, can be anything from 2 to 20+ panels per string. Shading of a panel will affect the voltage of the whole string, so we fit optimisers, basically voltage controllers that stop one shaded or damaged panel pulling the voltage down. They also send data down the DC cables so you can get realtime information from individual panels
