The solar energy that is most actively collected and converted to solar electricity is provided by the sun's radiation. Solar energy is used by many people in rural areas now as the sole source of electricity. Industrially, solar power is currently used for powering everything from waterfront desert desalinization plants to the powering of intracity rail systems. In fact, solar energy is now becoming a major consideration in the architecture of buildings and homes, both for conversion to electricity and for running a building's heating systems. The purpose of the information being presented to you here is to get you familiar with the current solar energy technologies and the best solar energy companies producing them so that you can make a good decision about solar energy.

DayStar Technologies is one of the leading solar energy companies. They have been able to significantly cut solar cell production costs by developing new manufacturing technologies. Their success in this field has been a large contributing factor the continuing increase in solar electricity installations.

Evergreen Solar is another of the leading solar energy companies today. However, as you might have guessed from the name, their focus is more on producing environmentally beneficial solar power products. They have put their manufacturing technological development efforts into how to product solar power products that are very unobtrusive and make use of environmentally friendly manufacturing processes and materials wherever possible.

For residential and light commercial solar energy applications most people seek out SunPower Corporation. This company produces and sells solar panels. The primary focus of SunPower Corporation is on increasing the space to electricity conversion ratio of its solar panels. They claim that their all-back-contact silicon-based solar cells produce 50% more power than conventional solar cells of the same size.

At the heart of most solar electricity units are the tools used in the manufacturing process of the core of the solar panel, the photovoltaic modules. The leading supplier of these tools is the Spire Corporation. The other companies mentioned often use these tools to enhance their manufacturing processes.

There are many other solar energy companies forming each year, but the ones discussed are the big players with established reputations. If you choose one of these newer companies or one of the smaller companies, make sure you do it based on good personal testimony of someone you know, that you check out the company thoroughly, or that you at least check the company out with the better business bureau.
