Usually, a photovoltaic power generation system is mainly composed of photovoltaic modules, controllers, inverters, batteries and other accessories. Battteries is a important part which can supply power to the load when system does not generate electricity at night or in cloudy and rainy days.
Photovoltaic(PV) modules are the core part of the system which convert solar energy into electricity. A PV module is made of two types of semicondauctors, called p-type and n-type silicon. When sunlight irradiate the PV modules electrons flow from the n-type to the p-type and form current.
Controllers are connected with PV modules by solar cables which can working in extreme environments. Controllers can get the working information of PV system at any time it make them can control the power out of whole system.

Inverters are devices that converts the direct current generated by photovoltaic power generation into alternating current. The photovoltaic inverter is one of the important system balances in the photovoltaic array system and can be used with general AC power supply equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and islanding protection.
In PV system solar cables play a role of connecter, connect all composites into a whole system. Because of the working environments of PV system are always outside, solar cables must be high quality and resistant to high temperature, acid and alkali. An excellent solar cable can have 25 years service life even more. Without solar cables power can not flow to appliances or batteries at all, so a high quality solar cable is very important.
