Basically, Solar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector. A variety of configurations is available at varying costs to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications.

There are many types by which we can get that

Freeze protection :

Freeze protection measures prevent damage to the system due to the expansion of freezing transfer fluid. Drainback systems drain the transfer fluid from the system when the pump stops. Many indirect systems use antifreeze (e.g., propylene glycol) in the heat transfer fluid. n some direct systems, collectors can be manually drained when freezing is expected. This approach is common in climates where freezing temperatures do not occur often but can be less reliable than an automatic system as it relies on an operator. The third type of freeze protection is freeze-tolerance, where low-pressure water pipes made of silicone rubber simply expand on freezing. One such collector now has European Solar Keymark accreditation.

Overheat protection :

When no hot water has been used for a day or two, the fluid in the collectors and storage can reach high temperatures in all non-drain-back systems. When the storage tank in a drain-back system reaches its desired temperature, the pumps stop, ending the heating process and thus preventing the storage tank from overheating. so active systems deliberately cool the water in the storage tank by circulating hot water through the collector at times when there is little sunlight or at night, losing heat. This is most effective in direct or thermal store plumbing and is virtually ineffective in systems that use evacuated tube collectors, due to their superior insulation. Any collector type may still overheat. High pressure, sealed solar thermal systems ultimately rely on the operation of temperature and pressure relief valves. Low pressure, open vented heaters have simpler, more reliable safety controls, typically an open vent. there are many types that will work on This stage. because this will work on daily need. today nowadays people are using this a huge percent of life.Because this equipment is very Important in India we can't use electricity. because in India there are Sun raise in the whole year that's why we can generate electricity.
