DAS Energy photovoltaic modules differ significantly from conventional glass-foil modules due to their low weight and are also ideally suited for roofs. DAS Energy's modules can also serve as a stand-alone power source for street lighting, surveillance cameras, parking meters, etc. In addition, DAS Energy is constantly developing new photovoltaic products, such as solar roof tiles with integrated photovoltaics, solar cells.

A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. Solar cells produce direct current electricity from sunlight which can be used to power equipment or to Overall the manufacturing process of creating solar photovoltaics is simple in that it does not require the culmination of many complex or moving parts. The term "photovoltaic" comes from the φῶς (phōs) meaning "light", and from "volt", the unit of electromotive force, the , which in turn comes. In 1989, the German Research Ministry initiated the first ever program to finance PV roofs (2200 roofs). Module performance is generally rated under standard test conditions (STC): of 1,000 , solar of 1.

This is the simplest type of standalone solar PV system, as it requires only two main components: a solar PV module or array and a DC load. The solar PV module or array is directly connected to the DC load, such as a fan, a pump, or a light, without any intermediate device.

Solar technologies are categorized as either passive or active depending on the way they capture, convert and distribute sunlight and enable solar energy to be harnessed at different levels around the world, mostly depending on the distance from the Equator. Solar energy is the from the 's and , which can be harnessed using a range of such as , (including ) and. Sunlight has influenced building design since the beginning of architectural history. Advanced solar architecture and urban planning methods were first employed by the Development of a solar-powered car has been an engineering goal since the 1980s. Early commercial adaptationIn 1878, at the Universal Exposition in Paris, successfully demonstrated a solar steam engine.
