Solar thermal water heating systems are the logical alter-native to heating water with off the grid 'costly' electricity.
Although solar thermal technology is one of the most affordable renewable energy technologies, the initial price is still too high for many low-income individuals in developing countries.
Solar space heating can be 25 or more times more cost effective than solar electric (PV) systems, and the systems are excellent DIY projects. Payback for these low cost solar heating systems can be as little as one year.
Before you embark on any of the solar projects listed below, you MUST do a solar site survey. This will ensure that you actually get enough sun on your collector to make it worthwhile. It only takes an hour, its fun, its easy and you will learn something about how the sun moves.
This is the first think we will be doing .... so check back and see our progress
