Should I try to use Photovoltaics(PV’s) to heat up water or spaces?

No! It would be better off utilizing solar thermal, also known as solar passive, methods which directly uses the warmth that comes from the sun to heat the water and the air. Technically you can use Photovoltaics (PV’s), but we highly recommended that you do not! Using PV’s as a high energy warming device would be a waste of resources because PV’s change the sun’s light into Direct Current electricity (DC electricity) at a very low efficiency level, approximately 15%. In sum, it is very ineffective and costly to use PV’s as a high energy warming device.
