Solar energy is now a term used often to describe solar photovoltaic panels, which can be used to produce electricity through sunlight. However the electricity generated is quite minimal. A much more efficient and practical use is to produce hot water.

Solar energy is one of the most abundant energy sources we have available to us. Even in mild climates there is still a large amount of solar energy, which can be captured. This energy can be used to generate electricity with solar cells, or through solar water heaters.

Solar water heaters in various forms have been used through history, however we are not taking a more scientific approach to capture as much solar energy to heat water within a smaller space. The water then has multiple uses, to heat homes and even swimming pools.

Solar water heaters are actually a lot more efficient at capturing solar energy than photovoltaic solar panels. Using the same foot print much more solar energy can be captured to heat water for washing and heating, and some solar water heaters are very cheap to produce.

One of the most popular and most reliable designs of solar water heater is the passive water heater. The passive water heater works on a basic design, using components, which can be sourced cheaply and even made by you at home with only basic DIY skills.

As stated, there are changes in the design of different solar water heaters, however here are the components used to construct a passive solar water heater. To begin with a suitable water storage vessel is required, the size will vary depending on your heating needs, the tank with also be black to capture as much solar energy as possible. To get even more energy into the tank, the tank is then placed within a solar collector box, which is insulated and also reflects more energy against the black tank.
