A photovoltaic cell is a solar panel, and a piece of aluminium does nothing, am I missing something here?
- cdu1 3mo agoI think the implication is you can use it to reflect additional light onto your photocell, improving the power output for a smaller cost than purchasing an additional cell.
- jstanley 3mo agoWhy aren't photo cells already manufactured to be like 90% mirrors then?
- hatthew 3mo agoSome guesses: - A lot more direction-dependent. - More maintenance related to keeping the right direction, maintaining more moving parts, etc. - Less convenient form factor, more susceptible to wind, more unsightly. - Less space-efficient, which matters for some applications like house rooftop installations.
