what are the waste products of solar energy?

Question

what waste products does solar energy have

Answer 1

If you are asking at the source i.e., at the sun, it would be helium and other larger molecules which are formed from the progressive nuclear fusion of smaller atoms staring with Hydrogen atoms as the raw material. But I really doubt if they can be called "waste" as traditionally "waste" is something "undesirable" created by a man-made process - the fusion happening in the Sun is not a man-made process, neither can we term the fusion products as "undesirable" from human perspective.
If you are talking of waste products generated by "using" solar energy on the earth, well there are literally none during the usage of solar energy. However, the wastes generated during manufacture of the solar cells/panels and their support apparatus like circuit boards/batteries/invertors and during their maintenance are indirectly wastes generated by using solar energy. Also, the gases/radiation expelled by the solar cells/panels and the support apparatus during their life-time can be termed as "wastes" as well.

Answer 2

In the case of a fully installed system, practically none.

A bank of solar panels generates electrical power with no emissions.

A system for heating water to make steam might release the spent steam into the air but water is not usually thought of as a waste product. The steam engines or turbines used to generate electricity need to be lubricated and the oil used to do this wears out and has to be replaced.

Both kinds of systems produce some waste during manufacture and construction.

Answer 3

The answer would depend upon how the solar energy is converted to a conventional power source. That process could create waste products.

Answer 4

Answer 5

Dark Matter. That is where black holes come from.

Answer 6

It gets heat, and it releases heat.
