Blog Article

1. System Design

• Load Calculation: Calculate the total power consumption of the electrical appliances that the solar power system needs to supply, including the power of lights, TVs, refrigerators, and other devices, to determine the required power generation capacity.


• Solar Panel Selection: Select solar panels based on the local sunlight conditions and the required power generation capacity. Consider parameters such as the power, efficiency, and size of the solar panels. Usually, crystalline silicon solar panels are commonly used due to their high efficiency and stability.


• Battery Selection: Choose a suitable battery to store the electricity generated by the solar panels. The capacity of the battery should be able to meet the electricity demand during cloudy days or at night. Lithium - ion batteries and lead - acid batteries are both common choices, each with its own advantages and disadvantages in terms of cost, cycle life, and energy density.


• Inverter Selection: The inverter is used to convert the direct current (DC) output of the solar panels and batteries into alternating current (AC) for use in household appliances. Select an inverter with appropriate power and conversion efficiency to ensure stable operation of the electrical equipment.

2. Equipment Installation

• Solar Panel Installation: Install the solar panels in a location with sufficient sunlight, usually on the roof or in an open area. Ensure that the installation angle of the solar panels is appropriate to maximize the absorption of sunlight. Use brackets and fixing devices to securely install the solar panels to ensure their stability and safety.


• Battery Installation: Install the battery in a well - ventilated, dry, and cool place to avoid high temperatures and humidity, which may affect the performance and service life of the battery. Connect the batteries in series or parallel according to the system design to meet the required voltage and capacity.


• Inverter Installation: Install the inverter near the battery and solar panels to minimize the length of the connection wires and reduce power losses. Connect the inverter to the solar panels and batteries according to the wiring diagram, and ensure that the wiring is correct and secure.

3. Wiring and Connection

• Wiring Selection: Select appropriate wires according to the current and voltage of the system. The cross - sectional area of the wires should be able to carry the maximum current of the system to avoid overheating and power losses. Use insulated wires to ensure electrical safety.


• Connection: Connect the solar panels, batteries, and inverter according to the designed circuit diagram. Use terminal blocks, connectors, and other components to ensure reliable connections. Pay attention to the polarity of the connections to avoid incorrect connections that may damage the equipment.

4. System Testing and Commissioning

• Electrical Safety Inspection: Before turning on the system, carefully check all wiring connections, insulation conditions, and grounding conditions to ensure that there are no electrical safety hazards.


• Solar Panel Performance Testing: Test the output voltage and current of the solar panels under different sunlight conditions to ensure that they are working properly and meeting the design requirements.


• Battery Charging and Discharging Testing: Charge and discharge the battery to test its charging efficiency, capacity, and discharge performance. Ensure that the battery management system is working properly to protect the battery from over - charging and over - discharging.


• Inverter Performance Testing: Test the output voltage, frequency, and waveform of the inverter to ensure that it can convert the DC power into high - quality AC power to meet the needs of household appliances.

5. System Monitoring and Maintenance

• System Monitoring: Install a monitoring system to monitor the operating status of the solar power system in real time, including the output power of the solar panels, the charging and discharging status of the battery, and the working status of the inverter. This helps to promptly detect any faults or abnormalities in the system.


• Regular Maintenance: Perform regular maintenance on the solar power system, including cleaning the solar panels, checking the wiring connections, and testing the performance of the battery and inverter. Replace damaged or aging components in a timely manner to ensure the long - term stable operation of the system.
