Solar security
There has been some comment lately about how efficient various inverters and battery chargers are. Many coming in at 80-90% efficient. This quite rightfully upsets those of us that demand 100% out of life. However when you look at solar panels and find they are only ~20% efficient it simply is intolerable.
AT STC (Standard Test Conditions) there is 1000W per square meter of sun. A 20% efficient square meter in area panel would only make use of 200W, 800W is wasted! 800 Watts that pollutes the environment, harms wildlife and contributes to global warming! This obviously needs to be addressed. One possibility occurs to me now after owning some Bifacial panels.
With transparent panels it may be possible to layer panels such that each layer would capture another 20% of the sun's energy. So that you get 200W from the first layer, the second layer now having 800 sun watts left to work from it could capture 160W. The third layer having 640W to work from would then capture 128W and so on. If I could do high level math I probably could calculate the total number of layers to use all the sun up but just using simple math I think I would be at it forever. But even getting to maybe 90% of sun utilization would likely mean about 10 layers (a guess). How hard would it be to make a 10 layer solar panel?
Hopefully government regulation will be instituted soon requiring solar panels to be made more efficient in the future.
