I've always wanted my own heliostat(s) as I think they'd be more useful than solar panels (at least for me) - sending concentrated sunlight and heat in through your windows.
But can't find any good design/plans for DIY or anyone selling one.
- jamiek88 7y agohttps://lm.solar/order/ https://lm.solar/order/ I have the vacuum mirror focusing upgrade pack. Works really well and I roughly calculate that you get 80% of the growing power from the sun as direct light. I use it for a part of the garden that never got light due to building and trees and was always soggy and damp. Nothing grew there very long, now I maintain native wildflowers and a butterfly garden there. It’s really cool. The heliostat follows the sun mechanically and also can tune in the focus with a vacuum system.
- turtlebits 7y agoIMO, $2500 seems extremely expensive for focusing 1.45m2 of light, especially when you can get at least 2.5kW of solar panels for the same price.
- natch 7y agoIt’s a completely different technology that’s solving a different problem. And sun tracking is more complex when you are reflecting onto a fixed point as opposed to simply pointing the surface (in the case of solar cells) toward the sun.
