solar energy application in the modern society more and more widely, so how sunlight into electricity? The main principle of solar photovoltaic power generation is based on direct current from solar photovoltaic (pv) effect. If it is a grid system, electricity power grid directly by grid inverter; If off-grid system, storage battery charging and discharging and load through solar controller. Beam of semiconductor and the influence of different effects on metal or insulators. Because there are so many free electrons in metals, so the conductivity change with the light completely negligible. At very high temperatures, insulators are still unable to inspire more electrons in the conduction. Between metal and an insulator has the conductivity of the semiconductor in the body of the binding force of the electron is much less than insulators, the photon energy of visible light stimulates its freedom from combination to conducting state, this is the photoelectric effect of the semiconductor. When the electric field exists in the local area of the semiconductor, light born carrier can accumulate, this is very different and there is no electric field. Charge accumulation can produce optical voltage at both sides of the electric field, this phenomenon is called light born v effect, hereinafter referred to as the photovoltaic effect. 1 a, grid solar power system. 2 single-phase grid-connected power generation system. Three-phase grid-connected power generation system, the second off-grid solar power system 1. 2 DC solar power system. Solar power system for communication. 3. Three ac/DC solar power system, off-grid solar power systems for solar systems have a preliminary understanding, you can get to know you need what kind of pv systems. South Texas sun has a special team of engineers, they can provide you with detailed solar data and design.
