In fact, there are almost as many reasons to start using solar power water heaters in your home as there are people in the world.
Solar power as defined by Wikipedia; is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.

Second, install an instant water heater with or without pumps. This does the job too and is recommended for condominiums. Thirdly, you could have a storage water heater. The storage water heater could be a good alternative to a solar power water heater. However, the downsides of a storage water heater is that you will have to turn on the electricity switch, wait a minimum of 10-15 minutes for the water to heat up before you can shower. One should also bear in mind that the hot water can suddenly turn cold if another person were to use hot water at the same time in another bathroom. Storage tank too is recommended only for condominiums if you do not favor units of instant water heaters on your wall.
Here are some pictures of the different water heaters :
Storage heater and instant heater uses electricity to generate hot water. Any electrical appliances per say consumes electricity. Solar heater on the other hand uses the heat of the sun to generate hot water, so it does not consume electricity at all. Cost and budget is always an issue when it comes to selecting the appropriate system for your home so we worked out a rough calculation to help you realize how much you could save by installing a solar power for your landed property.
Cost Comparison
Assuming you have 6 toilets and 5 family members. ( do not forget family members can increase, hence increasing the cost of electricity and additional instant/storage heaters )
