WebApr 4, 2024 · However, the solar input and the mains input are generally kept separate by the controller, so there is no grid interactivity happening. This is why such systems often need twin tank elements—one for the PV power, one for the mains backup. This is an excerpt from the Direct PV buyers guide. Read the full guide in Renew 163. WebAdvantages of hot water with photovoltaics. ☀ Use more solar power. Instead of feeing surplus solar power into the grid, use it yourself to produce hot water. You therefore reduce your energy costs. ☀ Protect the heating system. You extend the service life of your heating system because you can switch it off completely in summer.
WebPV panels are around 25% efficient. So at best, you are putting 25% of the suns heat into heating hot water. It's about the word and most expensive way to do it. The "exception" to this is if you use a heat pump style electric water heater. The heat pump gets you "free" energy by taking some of the heat out of the air.
