Introduction of Solar Energy

In the last two decades, photovoltaics (PV), also known as solar PV, has evolved from a pure niche market of small scale applications towards becoming a mainstream electricity source. A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. In 1931 a German engineer, Dr Bruno Lange, developed a photo cell using silver selenide in place of copper oxide.  Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the crystalline silicon solar cell in 1954. These early solar cells cost 286 USD/Watt and reached efficiencies of 4.5–6%. By 2012 available efficiencies exceed 20% and the maximum efficiency of research photovoltaics is over 40%.

Introduction of Solar Home System

Solar Home System is composed by Solar Panels, Inverters, Charger Controller, Battery, Cable, Mounting Bracket, which is applied to produce electricity for home use.

Solar Home System is quite suitable product in urban area and the place which is short of electricity. As the cost of solar products reduced, more and more family can bear the charge of solar products. These products apply to schools, hospitals, public halls and private housing, communication stations, weather station. Also can use as household appliances, lighting, communications equipment, meteorological equipment.

Our company’s main target is to make every family can use cheap solar energy and enjoy the new innovation of modern science and technology.

Working Principle of Solar Home System

This is an off-grid solar system which uses batteries to store the solar energy, at the same time, the solar system can be connected with the grid for utilization of grid power. The solar system uses battery power in priority, but when sunshine is not so good or loads consumption is too big which caused the battery power inadequacy, then the system can switch automatically to grid power supply. Meanwhile, the system can charge the batteries with grid power until batteries are fully charged. Then the solar system will switch back to battery power supply.
