1. Component of power generation system
(1) PV panels
PV panels (solar panels, solar panels, and solar photovoltaic modules) absorb light energy and convert light energy into electrical energy. PV panels commonly used materials include monocrystalline silicon, polycrystalline silicon, and amorphous silicon. The conversion efficiency of monocrystalline silicon is 14 to 20%, the conversion efficiency of polycrystal frogs is about 13%, and that of amorphous frogs is 8 to 10%.
(2) Electric storage equipment
At present, the power storage equipment of the off-grid power generation system is mainly maintenance-free, and the battery can reserve the electrical energy generated by the PV panels.
(3) Charge and Output Control Controllers
The role of the controller is to control the entire system to work stably and safely.
(4) Other mechanical equipment
2. Main cost components and influence factors of power generation system
(1) PV panels
At present, one of the main reasons for the solar energy industry to fully roll out is that the price of PV panels is too high and affects the PV system price of the entire system. In addition to controlling the unit price of PV panels, the most important thing is to control the number of PV panels used. Some points:
A. Power Generation: In a certain sense, the greater the required power generation, the more PV panels are used and the higher the cost. Properly controlling the power generation can properly control the cost.
B. Weather conditions of PV panels: It is obvious that in the same area, the same PV panel, it generates much more electricity on a sunny day than cloudy, which can explain the different regions of PV panels. The amount of use varies.
C. The latitude of the location where the PV panels are located. During the same day, the sun irradiates at different latitudes. This causes the same PV panel to produce different amounts of electricity at different latitudes in the same day.
D. PV board use environment For example, the PV board is used on the top of the mountain. In the day, there is no shelter to block the sunlight shining on the PV panel. The power generation capability is definitely good. If the PV board is used at the foot of the mountain, then the day will come down. There are more or less obstructions to block the sunlight shining on the PV panels. Therefore, if there is sunlight shielding material in the surrounding environment of the PV panels, it will affect the power generation capability of the PV panels to some extent.
(2) Energy storage equipment
How much power a user needs to supply power to a power generation system in a day determines the capacity of the energy storage equipment. The more power the power generation system uses to supply users each day, the greater the capacity requirements of the energy storage equipment and the higher the cost.
The average daily electricity consumption of users, the greater the user's daily electricity consumption, the higher the cost of energy storage equipment.
3, technical expertise
Matcher
The matcher effectively improves the power storage capability of the entire power generation system, plays an important supporting role for the key links of the entire system, effectively improves the stability and high efficiency of the entire system, saves the cost of the PV panels for the entire system, and reduces the system cost. The matcher has intellectual property protection.
PV panels absorb sunlight
The PV panels can effectively absorb sunlight and make greater use of the PV panels' power generation capabilities, greatly increasing daily power generation and reducing PV panel costs.
4, customers need to provide information
Class A, (1) system output maximum power;
(2) The user's electricity consumption per day, the power consumption of the electrical equipment and the length of use of each electrical equipment;
(3) User's local weather and climate conditions (countries, regions).
Type B, (1) User's length of use of all electrical equipment and various electrical equipment;
(2) User's local weather and climate conditions.
Note: The system is generally designed to generate enough daylight to generate electricity. It does not take rainy days into account. Therefore, the system will only be able to withstand the use of electrical equipment for one day. Customers have other requirements to consider.
