The cost of maintaining a residential solar system

The cost of maintaining a residential solar system is influenced by factors such as the type of fault, regional differences, and the qualifications and experience of the maintenance personnel.

Fault type

If the core component of a solar water heater, the vacuum tube, has problems such as cracking or leakage and needs to be replaced, the total cost of replacing one tube, including the price of a regular vacuum tube and the labor cost for on-site maintenance, has a certain range. If multiple vacuum tubes are damaged, the cost will increase accordingly.

The controller plays a crucial role in controlling water temperature, water level, etc. When a malfunction occurs, if it is merely a simple poor contact in the circuit or a software fault, the cost of on-site inspection and repair will be within a certain range. If the controller needs to be replaced, the total cost, including the price of a regular controller and labor costs, has a certain range.

Water tank leakage is a common fault. If the weld seam of the water tank leaks, the labor cost for the maintenance personnel to repair and weld it has a certain range. If the water tank is severely damaged and needs to be replaced, the price varies greatly depending on the capacity and material of the water tank. Adding the cost of labor installation, the total cost of replacing the water tank also has a corresponding range.

The cost of repairing a leaking water pipe is usually within a certain range. The cost of replacing valves is usually within a certain range. Controller malfunction repair may require certain costs, depending on the specific extent of the damage and the time needed.

Regional differences

In first-tier cities, the cost of living is relatively high, and labor costs are also relatively high. The on-site repair fee for solar energy is usually within a certain range, and the specific repair price depends on the type of fault. For instance, the total cost of replacing a vacuum tube and the total cost of replacing a controller both have corresponding ranges.

The cost of living and labor in second-tier cities is relatively lower than that in first-tier cities, and the on-site service fee for installing solar panels is approximately within a certain range. For some common fault repairs, such as the total cost of replacing vacuum tubes and the total cost of replacing controllers, there are corresponding ranges.

In third-tier and lower cities, the cost of living and labor is relatively low, and the on-site service fee for installing solar panels is usually within a certain range. The total costs for replacing vacuum tubes and controllers both have corresponding ranges.

Qualifications and experience of maintenance personnel

Professional brand after-sales maintenance personnel usually undergo professional training, possess rich maintenance experience and high technical proficiency. The cost of on-site maintenance is relatively high, generally a certain proportion higher than that of ordinary maintenance personnel, but the quality of maintenance is more guaranteed, and they can diagnose and solve problems quickly and accurately.

The cost of on-site repair by ordinary maintenance personnel is relatively low. They may not have received systematic training from professional brands, but they do have certain repair experience and can handle some common faults. However, when repairing complex faults, they may need to spend more time and effort, and the repair quality may have some uncertainty.
