The demand for solar-generated electricity is booming due to the many benefits of this natural source of energy. At the top of the list of benefits are attractive incentives offered by state and federal governments, in addition to monthly savings in ever-increasing electricity costs. Advancements in solar technology have made solar energy a popular alternative to traditional energy sources.
The potential benefits of solar energy are greatest in warm states like California, which has areas that experience high sunlight levels throughout the year. These benefits include a reduced dependence on nuclear power and fossil fuels. read full article on the advantages of solar energy
The science of modern solar power began in 1839 when a French physicist accidentally discovered that the sun's rays emit energy. These led to further experimentation on what is known as the "photovoltaic effect" over several decades, until the first solar photoelectrical cell was built in 1877 by an English engineer named Willoughby Smith.
Albert Einstein conducted research into the photovoltaic effect and was awarded the Nobel Prize in 1912 for his discoveries. By 1955, the commercial production of solar photovoltaic cells was underway. The first large scale use of solar cells was to power the Vanguard I satellite, which was launched in 1958. Since then, developments in the field of photovoltaics have continued at a rapid pace. read full article on how solar power works
Installing a solar power system can be one of the more expensive home improvement projects. However, realtors have rated installation of a solar photovoltaic (PV) power system or solar hot water system as a guaranteed way to add value to a home, equivalent to projects like building a deck or completing a kitchen remodel. An added advantage that a solar power system has over a kitchen remodel or deck addition is the continuing benefit of lower power bills. read more about How Solar Power Works
Other benefits that can be realized from a solar power system include financial incentives that are available in many areas. Federal, state and local governments as well as utility companies provide rebates and other forms of incentive. This helps drive down the up-front costs that are part of solar power installation. read full article on solar power system cost

The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.
Earth's land surface, oceans and atmosphere absorb solar radiation, and this raises their temperature.
