Applied Technical Services provides photovoltaic testing for modules and systems. A photovoltaic system generates electricity from light, primarily from the sun using semiconductor materials. Some common products that use photovoltaics are calculators, cell phone chargers, laptop computers, keyboards, flashlights, fans, radios, watches, and lighters. Other large-scale uses, in addition to supplying energy to homes and commercial buildings, are air conditioning units, furnaces, dryers, road signs, streetlights, and vehicles (golf carts, short range shuttles). ATS’ photovoltaic experts can assist in validating module performance and reliability. Testing allows companies to effectively and efficiently bring product to market at a competitive advantage.
ATS’ labs provide photovoltaic testing and inspection with verifiable results. The photovoltaic device industry is one where the importance of accurate analysis for private businesses, governments, financial investors, and developers require substantive information for critical assessments. Our engineers are highly qualified to implement the technology and methodology to test and determine if the photovoltaic devices and equipment are suitable for their intended operating use and life span.
