The photovoltaic array generates electricity (typically 18–22% panel efficiency), which powers a heat-pump compressor that moves ambient heat into water with a COP (Coefficient of Performance) of 2–4. Solar thermal systems use roof-mounted collectors. . Solar water heating is a straightforward way to reduce reliance on traditional gas or electric water heaters, cutting energy bills significantly. This technology is most efficient in sunny areas and tends to perform best when there is a high demand for hot water. Since it directly harnesses solar. . On average, if you install a solar water heater, your water heating bills should drop 50%–80%. Also, because the sun is free, you're protected from future fuel shortages and price hikes. If you're building a new home or refinancing, the economics are even more attractive. They can be used in almost any climate — not just regions with a lot of sun and heat. The return on investment (ROI) is generally better with PV panels.
