Is there solar hot water in 5 degree weather?

I can't. The temperature of 5 degrees is too low for sunlight to convert solar energy into heat energy. The temperature of water in solar energy is also low. Solar water heater is a kind of heating device that converts solar energy into heat energy and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms, mainly vacuum tube solar water heaters.
