Answer
A solar water heater is a device that uses solar energy to heat water. Sunlight is allowed to fall on copper pipes painted black. The pipes are fixed on a wooden box with a glass cover. Reflectors may also be used to increase the effective area over which sunlight is collected. Water flowing through the copper pipes gets heated up.
Solar water heaters are commonly seen on roofs of large buildings and hotels. They supply hot water for various purposes.
