has PV finally overtaken solar hot water?
- Calwestjobs 2y agowell just piping for hot water system is more expensive then PV panels. But biggest expense is instalation costs(humans) so it depends how you calculate. But PV system can be used for hot water, tv, car, charging kids bikes, lawnmower etc. Solar thermal can be used only for hot water (or cooling if you use multistage heat pump but that is viable only in office buildings or hockey stadiums and such).
- Calwestjobs 2y agoby multistage heat pump i meant https://en.wikipedia.org/wiki/Absorption_refrigerator https://en.wikipedia.org/wiki/Absorption_refrigerator i.e. rv propane refrigerator.
- kragen 2y agoHow much does the piping cost?
- Calwestjobs 2y agoeven with tariffs in place, whole PV system will provide you more kWh per year per $ invested then solar thermal system. rated output is not what you get 100% of time. price per performance is crucial. price per imaginary watts is nonsense.
- kragen 2y agoYou're probably right, but do you have some idea how much the piping costs for a solar thermal hot water system? Because that's what I was asking about.
