Solar Water Heating has been used for hundreds if not thousands of years to heat water. With advances in technology solar water heating systems have become more and more efficient, with Evacuated Tube Solar Water Heating offering efficiencies of well. That means that more than 90% of the sun’s energy landing on a surface is converted into heat which can be used to heat water. This is also one of the cheapest (fastest payback period) renewables, and a lot more cost effective compare to PV solar panels. Solar energy is also a potential solution to the environmental problems being caused by fossil fuels specially in Iran which has been located in a suitable area. When fossil fuels are burned to generate electricity, they release harmful greenhouse gases into the atmosphere. Scientists believe that continuing to depend on fossil fuels is going to cause serious environmental problems in the future. And it’s considerable that as time passes by we are running out of fossil fuel so it would be essential to look for other greener resources
