This one has to be too good to be true. https://www.ebay.com/itm/1500w-Flexible-Solar-Panel-Kit-System-120A-Controller-3000w-Inverter-House-Boat/333107282098 Says it includes 15 100W panels, connecting cables, inverter etc. for $89. Dunno what else would be required to tie it into a domestic power supply, but at that price it's highly tempting. Would definitely take a bite out of the air conditioning bill in summer, if it's anywhere near as good as it claims.Better control systems using PWM and MPPT can wring the best out of a PV panel. I've a long south facing front on my shop building. It could use an awning angled to 44.25 degrees, covered with solar panels. I'd have to cut down a tree but I'm thinking of doing that anyway because it's an evergreen that constantly drops seed pods and needles. IIRC if your panels aren't on movable mounts the best compromise is to angle them to match your degrees latitude.
