Solar water heaters have been around for hundreds of years. For over 50 years people have been using them to heat everything inside and outside the home. Over the years, these solar water heating systems have become much more efficient. If you are located in sunny areas of the country, you should look into buying a solar water system.
In recent years smaller solar systems have become available that the average person can use at a relatively low cost. They might not be able to power your home, but they can power many of your smaller electronics and help you reduce the amount of energy you consume. Search for some smaller systems to help reduces your carbon footprint.

The best time to incorporate solar power into the design of a home or building is in the initial construction. Windows are best facing south to let maximum sunlight (hence greenhouse heat) in during the winter. Likewise, avoid windows facing directly into the summertime sun to keep things cooler, so less power is needed for fans or air conditioning. The maximum roof space, however, should always get sunlight exposure.
Keep in mind that purchasing a solar power system often enables you to receive tax credits from the government. You may find that you get back as much as 30 percent of the total cost of your system. So, if you look into a system and think that it costs too much, investigate whether or not you will get credit back to determine how affordable it actually is.
