solar power

[jlordy20]

If i placed my solar power lights in my greenhouse throughout the day, will it carge the batteries up better? due to the heat?

[Toureman]

No, they don't work on heat just light.

[enfable]

They should charge better if you redirect additional sunlight at them using mirrors

[buildersmate]

In fact they would charge rather less well because the glass inevitably obstructs a small amount the UV spectrum trying to pass through.

Monocrystalline silicon solar cells produce a voltage when visible light and infrared light (above a critical frequency) are absorbed. Your batteries will be charged more efficiently outside as it is much cooler.
The infrared radiation from a hot greenhouse is far too low in energy to produce a voltage from a solar cell, it must come directly from the Sun.
