How To Choose Solar Photovoltaic System Supplier

Solar photovoltaic system is a device system that uses battery components to directly convert solar energy into electrical energy. Under light conditions, solar cell components generate a certain electromotive force, and through the series and parallel connection of components, a solar cell array is formed, so that the array voltage meets the system input voltage requirements.

System Composition

The solar photovoltaic system is mainly composed of photovoltaic panels, battery groups, controllers, inverters, AC distribution cabinets, junction boxes, bracket systems, dust removal systems, etc.

The solar cells and batteries form the power unit of the system, so the battery performance directly affects the system working characteristics.

(1) Battery unit: Due to technical and material reasons, the power generation of a single battery is very limited. The solar cells in practical use are battery systems composed of single batteries connected in series and parallel, which are called battery modules (arrays).

(2) Energy storage unit: The direct current generated by solar cells first enters the battery for storage. The characteristics of the battery affect the working efficiency and characteristics of the system. Battery technology is very mature, but its capacity is affected by the end power demand and sunshine time (power generation time). Therefore, the battery watt-hour capacity and ampere-hour capacity are determined by the predetermined continuous sunshine-free time.

Determination of System Power

To install photovoltaic panels, we first need to know how many kilowatts of system you need. Generally speaking, we will configure a solar photovoltaic system for you based on your daily electricity consumption. If you do not know your daily electricity consumption, we can calculate it in the following two ways:

1. The total power of major household appliances.

2. Electricity bill. We can calculate your daily electricity consumption through your electricity bill for a certain period of time.
