Key points for daily operation and maintenance of wind and solar hybrid systems

The long-term reliable operation of wind and solar hybrid systems is inseparable from simple but continuous daily maintenance. Developing good inspection and maintenance habits can detect hidden dangers in advance, ensure power generation efficiency, and extend the life of equipment.

1. Daily/weekly quick check points

These checks are simple and easy to do, and it is recommended to develop a habit:

View the controller display: Take one minute each day to view the system controller display. Pay attention to whether the current total power generation and battery power percentage are normal, and whether there is an alarm code. This is the most direct way to understand the "health" of your system.

Visual inspection of critical equipment:

Solar panels: Observe the surface weekly for obvious covering, such as bird droppings, fallen leaves, thick dust or snow, which can seriously reduce power generation efficiency.

Fan: Check whether the blades are intact and whether there are foreign objects (such as plastic bags, kite strings) entangled. When the wind is strong, listen to whether the fan is running smoothly and whether there are any abnormal friction or impact sounds.

Battery area: Keep dry, clean and ventilated, and check the terminals for signs of looseness or corrosion.

2. Regular cleaning and basic maintenance

Depending on the degree of environmental pollution, conduct this once every 1-3 months:

Cleaning solar panels: In the early morning, evening or cloudy days when the surface temperature is not high, wipe the surface with a soft cloth or sponge dipped in clean water. Avoid using hard objects or corrosive cleaners. Keeping the board surface clean can increase power generation efficiency by 5%-15%.

Check fasteners: Check and tighten bolts at solar panel brackets, wind turbine tower poles, and all cable joints. Long-term exposure to wind and sun outdoors can easily lead to loosening, affecting safety.

Check the wiring and grounding: Check the outdoor cable sheath for signs of aging, damage, or gnawing by animals. Make sure all equipment has a solid ground connection, which is critical for lightning protection.

3. Seasonal and special maintenance

Coping with severe weather:

Before strong wind/typhoon: Check all structural fasteners to ensure that the wind turbine brake or protection function is normal.

After heavy snow: Clean the snow on the solar panels promptly.

After the thunderstorm season: Comprehensively check the status of the lightning arrester and grounding resistance.

Battery maintenance (for lead-acid batteries): Check the battery terminals monthly for corrosion, and apply special grease after cleaning. Make sure the battery compartment is ventilated to prevent hydrogen gas from accumulating. For lithium batteries, it mainly relies on the battery management system to maintain a suitable environment.

Data recording and analysis: Check the historical power generation data of the system regularly (such as monthly) and compare the changes in power generation in different seasons and weather. If it is found that the power generation continues to decrease abnormally, the problem can be determined based on the inspection results.

4. Abnormal situation handling and safety first

In case of abnormality, cut off the power first: When you find that the system has obvious abnormal noises, smoke, burnt smell, or the controller continues to alarm, you should first safely disconnect the system according to the operation manual (usually disconnect the battery first), and then contact a professional. Do not disassemble it yourself.

Safe operation: All maintenance work must be performed after the system is completely powered off. When cleaning or inspecting equipment at height, use a stable ladder and have someone assist you to ensure personal safety.

Summary: Observe frequently, focus on prevention, and ensure safety

The core of daily maintenance lies in "diligent observation, early detection, and emphasis on prevention." It doesn't require advanced skills, but it does require care and persistence. By integrating maintenance into your daily routine, you can become the "first steward" of your own energy system, ensuring that this green investment can continue to bring you brightness and convenience. The reliability and longevity of a system that is well cared for will far exceed expectations.
