Solar Water Heaters – Great Way To Save Money on Water Heating Bill
Solar water heaters can help you save up to 70% on your water bills. Apart from the environmental benefits of solar energy, the financial benefits make it worth the effort. Homes that have both PV panels and solar water heating systems can benefit from even greater financial savings. Although installing solar heating systems can be costly, grants are available to supplement solar technology costs. Another option is to create your own solar panels.
In this climate of global warming and decreasing oil reserves, it makes sense to turn our attention to natural and renewable sources. The silent, pollutant-free energy produced by solar water heating systems have made these the most popular source of alternative energy.
Using photovoltaic panels (solar panels) while staying connected to the grid, is the most common way of switching to solar energy. The grid is then fed with any surplus electricity generated by your solar system. This enables you to sell any extra electricity that you may produce, and to buy in electricity when, at night, your panels are not absorbing sunlight.
Electricity created using photovoltaic cells is not the only form of solar energy available. Solar-thermal panels use the sun’s heat to make hot water instead of electricity. There’s no electricity involved in the use of solar-thermal panels, they work in a very different way to PV panels.
Covered in black glass, the purpose of solar-thermal panels is to absorb the sun’s heat. Hot water is created by directing water between the solar water heaters panels, heating it as it goes, after which it is channeled into the water system and of course, comes out of the faucets as hot water.
