Improvements to solar panels rich in opportunity for homeowners and businesses

improvements to solar panels

Improvements to solar panels increase the benefits of adding solar energy to your home.

Solar panels do magic up there on the roof turning the rays of the sun into electric energy. It’s amazing. And, it’s only getting better. Better?! Yes, better. There are improvements to solar panels making them more efficient all the time.

The modern solar panel was introduced in 1954 as a product of Bell Laboratory. Three of the company’s scientists – Calvin Fuller, Daryl Chapin and Gerald Pearson – used silicon to create a source for collecting solar energy. It was a stable and reliable source of energy but it was hardly efficient. And it was expensive – really expensive.

Congressional act promotes development

In 1978, Congress enacted the Public Utility Regulatory Policy Act and the Energy Tax Act. This was the government’s first step towards promoting and encouraging the development and increased use of solar energy. As a result, by the 1990s, the National Renewable Energy Laboratory developed a photovoltaic (PV) panel, using gallium indium phosphide and gallium arsenide, that achieved an incredible efficiency rating of 30 percent. Unfortunately, it was not a reasonable panel for mass production.

In 2000, Sandia Laboratories improved the efficiency of solar panels with the development of an inverter that converts the Direct Current (DC) of solar panels to the Alternating Current (AC) that is used in homes. The advancement launched the solar panel industry as a serious alternative to complete reliance on the electricity generated by utility companies.

Solar panels today generally produce more than 20 percent efficiency ratings. While companies developing solar panels are consistently seeking to improve on efficiency, improvements to solar panels are already at hand in terms of mass production. Hand-in-hand, with mass production, the costs of solar panels has come down dramatically.

Panels today are lighter and easier to install. There are also improvements in the inverters, including hybrid string inverters and microinverters that transform the energy from DC to AC for each individual panel.

The gist is that, as solar panels continue to improve, we have already seen vast improvements to solar panels over what was available before. This is good news for reducing our reliance on fossil fuels and it’s good news for homeowners and businesses that want to save on energy costs while reducing their dependence on utilities.
