Solar power generation system consists of solar battery, solar controller, battery (group). If the output power is 220V ac or 110V ac, you need to configure an inverter. The functions of each part are:
Solar energy panel
Solar panel: Solar panel is the core part of the solar power generation system, but also the most valuable part of the solar power generation system. Its role is to convert the sun's radiation capacity into electrical energy, or sent to storage batteries, or to promote the load work. The quality and cost of solar panels will directly determine the quality and cost of the whole system;
Solar energy controller
Solar controller: The role of the solar controller is to control the working state of the whole system, and the battery overcharge protection, overdischarge protection. In the place of large temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switches and time control switches should be optional for the controller;
battery
Battery: generally lead-acid battery, small and micro system, can also be used nickel metal hydride battery, nickel cadmium battery or lithium battery. The idea is to store the electricity generated by the solar panels when the light is on and release it when needed.
inverter
Inverter: In many occasions, need to provide 220VAC, 110VAC AC power supply. Because the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. To supply electricity to 220VAC appliances, the direct current energy from the solar power system needs to be converted into AC power, so DC-AC inverters are used. Dc-dc inverters are also used in some situations where multiple voltage loads are needed, such as to convert 24VDC power to 5VDC power (note that this is not a simple step-down).
Factors affecting the
The design of solar power system needs to consider the following factors:
Q1. Where is the solar power system used? What is the solar radiation in this area?
Q2, how much load power of the system?
Q3, What is the output voltage of the system, DC or AC?
Q4. How many hours does the system need to work every day?
Q5. How many days does the system need to supply power continuously in rainy days without sunlight?
Q6, load situation, pure resistance, capacitance or electrical sensitivity, how much starting current?
Q7. Quantity required by the system.
