Solar power is usable energy generated from the sun in the form of electric or thermal energy. Aside from using photovoltaics to generate electricity, solar energy is commonly used in thermal applications to heat indoor spaces or fluids. Residential and commercial property owners can install solar hot water systems and design their buildings with passive solar heating in mind to fully take advantage of the sun's energy with solar technology. Interested in benefiting from solar power? Solar panels are installed at three main scales: residential, commercial, and utility. Residential-scale solar is typically installed on rooftops of homes or in open land ground-mounted and is generally between 5 and 20 kilowatts kW , depending on the size of a property. Commercial solar energy projects are generally installed at a greater scale than residential solar.
In theory, solar energy was used by humans as early as 7th century B. Later, in 3rd century B. These sunrooms used massive windows to direct sunlight into one concentrated area. Some of the iconic Roman bathhouses, typically those situated on the south-facing side of buildings, were sunrooms.
Later in the s A. In the late s EEnergy s, researchers and scientists had success using sunlight to power ovens for long voyages. They also harnessed the power of the sun to produce solar-powered steamboats. The development of solar panel technology was an iterative one that took a number of contributions from various scientists. Naturally, there is some debate around when exactly they were created and who should be credited for the invention.
A brief history of solar power
Some people credit the invention of the solar cell to French scientist Edmond Becquerelwho determined light could increase electricity generation when two metal electrodes were placed into a conducting solution. However, solar cells as we know them today are made with silicon, not selenium. The first ever silicon solar cell could convert sunlight at four percent efficiency, less than a quarter of what modern cells are capable of. It spans various industries and contributes power to hundreds of different gadgets and technologies.

When was solar energy first used?
Inthe Vanguard I satellite used a tiny one-watt panel to power its radios. InNASA was responsible for launching the first Nimbus spacecraft, a satellite able to run entirely on a watt solar array. The University of South Wales broke that record again in when researchers Enerby NASA broke that record in when they reached 96, feet with their non-rocket aircraft.
InPresident Barack Obama requested that solar panels and a solar water heater be installed on the White House. Consider this: since the yearsolar panel prices have dropped by at least 10 percent every single year.

It is a pity, that now I can not express - I hurry up on job. I will be released - I will necessarily express the opinion on this question.
Unequivocally, a prompt reply :)
