Solar panels should also be inclined at an angle as close to the area's latitude as possible to absorb the maximum amount of energy year-round. Solar cells are made of the same kinds of semiconductor materials, such as silicon, used in the microelectronics industry. Photovoltaic cell is the basic unit of the system where the photovoltaic effect is utilised to produce electricity from light energy. All solar power systems work on the same basic principles. Depending on factors like temperature, hours of sunlight, and electricity use, property owners will need varying amounts of solar panels to produce enough energy. Rebates & Incentives . Some science behind PVs is well over a century old—Albert Einstein’s 1905 explanation of the photoelectric effect won the Nobel prize in physics in 1921. While n-type semiconductor and p-type semiconductor contact each other, the free electrons near to the contact surface of n-type semiconductor get plenty of adjacent holes of p-type material. Now to understand this whole concept of Solar power plant we need to understand some basic concepts first. As an example, the multijunction device below uses a top cell of gallium indium phosphide, "a tunnel junction," to aid the flow of electrons between the cells, and a bottom cell of gallium arsenide. Depending on the functional and operational requirements of the system, the specific components required may include major components such as a DC-AC power inverter, battery bank, system and battery controller, auxiliary energy sources and sometimes the specified electrical load (appliances). Solar thermal panels are used in conjunction with a boiler, collector or immersion heater. no builders work is required). Other grant options. Other reasons batteries are used in PV systems are to operate the PV array near its maximum power point, to power electrical loads at stable voltages, and to supply surge currents to electrical loads and inverters. Simply put, PV systems are like any other electrical power generating systems, just the equipment used is different than that used for conventional electromechanical generating systems. Non-tracking PV systems in the Northern Hemisphere should ideally point toward true south, although orientations that face in more easterly and westerly directions can work too, albeit by sacrificing varying degrees of efficiency. The solar modules absorb sunlight and convert to electricity to store in battery or power the loads.
