As of now, more than onemillion households in China have installed distributed solar PV applications.As the world’s leading solar technology company, LONGi’s distributed solar PV solutionshave been deployed across the whole world, ushering in an era in which solar energy is accessible to everyone. In thisand a forthcoming series of articles, we aim to provide a comprehensive introductionto distributed PV.

1: Whatis Solar PV power generation?
Solar PV power generationis a technology that directly converts solar energy into electricity via the photovoltaic effect of a semiconductorinterface. The key element of the technology is the solar cell. After beingconnected in series, the cells are packaged and protected to form a large-areasolar module and then combined with components such as a power controller toform a PV power generation device.

2: Whatis distributed PV?
A distributed PV power projectusually refers to a power generation system that uses decentralized resources, has a smallinstalled capacity and is arranged in proximity to its users. It is generallyconnected to the power grid with a voltage level lower than 35kV. It is a relativelynew type of power generation and energy utilization mode and has broaddevelopment prospects. It advocates the principles of local power generation,local grid connection, local conversion and local use. It can not onlyeffectively increase the energy generated by PV projects of the same size, but canalso solve the problems of power loss during simultaneous boosting andlong-distance transmission. Put simply, you can install a small solar power projecton your own roof or in a nearby open space at any time, not only reducing electricitybills, but also lowering energy consumption.
3: What attractspeople to install distributed PV?
Some may question whatmoves millions of households worldwide to install distributed PV? It is definitely not to follow a fashionabletrend. Distributed PV actually boasts a number of significant advantages.
1. Low carbon andenvironmentally friendly. No noise, no air, no water pollution.
2. High levels of safety. A power generation system independentof the grid, avoiding problems caused by large-scale power outages.
3. Cost. Low transmission and distribution loss and lowinstallation costs.
4. Profitable. In addition to receiving state subsidies, userscan also "sell" excess electricity to the power grid.

LONGi, focusing this yearon the differentiated needs of the distributed PV market, has now launched itsnew 66C Hi-MO4 monofacial module (Hi-MO4m) which, together with 60C and 72C options,can be widely used on residential and industrial and commercial roofs.
