Sources of Solar Energy
When it comes to saving on your utility bill, solar energy can be quite affordable and easier to harness than hydroelectric, tidal wave and nuclear sources that are being tested for commercial use. Many people can save 30% to 50% on their utility bills using solar energy. Sources of solar energy can be passive or active and used for residential or commercial applications. Many people are familiar with solar panels that collect the sunshine, but they don't know much about the entire system.

Sources of solar energy involve active solar systems that use solar panels, photovoltaic cells, battery storage and power inverters and passive solar energy techniques which positions a home to take advantage of natural sunshine and features that magnify it.
Sources of solar energy that are passive might include an earth contact home that takes advantage of the earth's natural insulating values and a southern exposure in a northern climate to take advantage of the sun's warming rays during winter months. In the summer months, the sun moves towards the northern sky and the home is insulated and kept cool during the hottest part of the day and summer.
An example of active sources of solar energy are the home solar power systems that many people are installing from kits that cost a few hundred or building their own from guides and manuals. You can buy active solar panel systems that are professionally installed, but they can cost several thousand dollars for a whole house system, although utility company rebates and tax incentives can lower the prices.
If you sell power back to your utility grid, then you can receive free energy and actually make money from your additional power generation. What many people find is that this amount might be capped by the utility, and they may need to use some electricity during a rainy period or a long period of cloudy days. Either way, this is one of the most reliable sources of solar energy for most people.
The most innovative homeowners may use a combination of passive solar energy and active solar energy to save on their utilities. Many of these enterprising homeowners cut their utility bills to nothing and can rely on the sources of solar energy to power their entire home. By building your home to take advantage of passive sources of solar energy and using active sources of solar energy, you may never have to worry about utility bills again.
Understanding the passive sources of solar energy can help you if you are building a new home more than an existing one, however, you can still use window treatments, skylights and carefully placed windows to let sun in during winter months and keep it out during summer months. You can supplement it with active sources of solar energy, such as a backyard solar power system. You can find guides, manuals, kits and professional installers on the Internet, with homemade systems costing as little as $200.
