Overlapping doesn‘t work due to the fact that individual small cells of a bigger panel - when shaded - greatly diminish the output of the entire solar panel.

- hinkley 2y agoAnd yet they left the focal point and its support poles there. No I agree with the people calling bullshit/publicity stunt. This array irritates me.
- ambyra 2y agoYeah when I read the title I thought they were covering the old dish with mirrors and putting a collector at the focal point. This is much less interesting :(
- hinkley 2y agoRight!?
- robocat 2y agoI presume they point the dish at the sun, so the shadow is in a fixed position. However the video shows during installation so not pointing at sun - but shadows that you see don't appear significant
- hinkley 2y agoSolar cells in shade act as diodes. They block the flow of electricity. It’s why we are doing inverters per panel now.
- robocat 2y agoThanks - I didn't realise shade losses could be so significant. I did find panels designed to avoid shade losses due to a single cell in a string being shaded but such panels appear to be uncommon or expensive.
- hinkley 2y agoWhat really bothers me most about this problem is that it makes you have to choose between solar panels and trees, and that’s a shitty bargain. Trees are good, and they lower your AC bill.
