[QUOTE="Rick, post: 635127, member: 317022"] As far as heating water goes there should be very little corrosion and maintenance in a solar heating system. The idea is that solar heating works on convection and the same water is circulated through the system and is passed through a heat exchanger which heats water in a storage vessel. As the water in the panels and the water to be used never comes into direct contact Inhibitors can be put into the system to prevent the corrosion of the pipe work etc, much in the same way that central heating systems are treated. Certianly in the UK it is mostly a false economy to install solar heating as we don't get anywhere near enough sun. However in a country such as Israel I would expect solar heating to be much more economic. Solar heating is usually used to boost the temperature of the water so that the boiler has less work to heat the water to its final temperature. i.e it takes less energy to heat water from 20 - 65 degrees than it does to heat the same water from 10 - 65 degrees. I am not very familiar with the electric side of things but I would guess that a combination of solar cells and wind driven turbines could be used to produce electricity. Not sure how much help that is :confused: [/QUOTE]
