Guide de montage solaire : Augmenter l'efficacité et prolonger la durée de vie
With the rapid popularization of clean energy today, rooftop solar panels have become a common sight in every household. As the key framework supporting these power generation panels, the maintenance and optimization of solar brackets directly affects the power generation efficiency of the entire system. This article will explain to you in an easy-to-understand way how to make solar brackets more durable and more efficient in power generation through simple maintenance and intelligent upgrades.
Part 1: Four Practical Tips for Bracket Optimization
To make your solar bracket more stable and efficient, remember these three key points:
1.1 Choose the right bracket structure
Just like building a house requires a good foundation, the bracket design directly affects stability:
- Load-bearing calculation: Professional installation will accurately calculate the weight that the bracket can bear (including the weight of the photovoltaic panel and the pressure of snow)
- Wind-resistant design: The bracket shape is designed according to the maximum local wind force, just like the frame of an umbrella must be able to withstand strong winds
- Installation type: Triangular brackets are used for flat roofs, hook-type brackets are used for sloped roofs, and foundations are required for ground installation
Tips: The optimized bracket uses less material and can reduce costs by about 15%
1.2 Choose the right material to increase service life
The bracket material is like putting on protective clothing for it:
- Daily environment: Ordinary steel + galvanized treatment (similar to the anti-rust process of iron barrels)
- Seaside/humid areas: It is recommended to choose aluminum brackets or stainless steel materials (similar to high-end kitchenware materials)
- Anti-corrosion treatment: Common treatments include hot-dip galvanizing (putting metal protective clothing on steel) and plastic spraying (similar to car painting)
Example: The service life of a galvanized bracket can be extended by 5-8 years compared to ordinary steel
1.3 Proper angle improves efficiency
Adjusting the bracket angle is like “posing” the solar panel:
- Fixed angle: Set according to the local latitude (for example, a 30-degree inclination is recommended for areas at 30 degrees north latitude)
- Adjustable angle: Maintain the standard angle in spring and autumn, increase by 5-10 degrees in winter, and decrease by 5-10 degrees in summer
- Spacing design: The spacing between two adjacent rows of brackets = bracket height × 1.5 times (avoiding the front row blocking the back row)
Measured data: Correctly adjusting the angle can increase annual power generation by 8%-12%
1.4 Smart tracking is more efficient
Equip the bracket with a “sunflower system”:
- Single-axis tracking: The bracket automatically rotates 180 degrees every day to chase the sun (suitable for flat installation)
- Dual-axis tracking: The angle can also be adjusted up and down (power generation can be increased by up to 35%)
- Energy-saving design: The new tracking bracket consumes ≈ 1 LED bulb (about 0.05 kWh) per day
Reminder: The tracking system is more suitable for areas with more than 2,000 hours of sunshine per year
Part 2: Personal bracket maintenance manual
2.1 Daily maintenance list
Maintenance according to this schedule:
| Cycle | Inspection items | Tool preparation |
|---|---|---|
| Monthly | Bolt tightness, surface cleaning | Wrench, soft brush |
| Quarterly | Anti-corrosion coating inspection, structural deformation | Flashlight, tape measure |
| Yearly | Overall load-bearing test, angle calibration | Level, professional inspection |
2.2 Seasonal maintenance focus
- Spring: Check whether the winter snow has caused deformation (focus on the connection)
- Summer: Check if there is water accumulation at the bottom of the bracket within 48 hours after rain
- Autumn: Clean up fallen leaves and bird nests (to prevent obstruction and corrosion)
- Winter: Clean up promptly after snowfall (use a special plastic shovel)
Special note: Snow accumulation exceeding 10 cm needs to be cleaned up immediately
2.3 Response to sudden weather
Do this in case of special weather:
- High wind warning: Turn the adjustable bracket to horizontal mode (reduce the area exposed to wind)
- Heavy rain is coming: Check if the drainage trough is unobstructed (to prevent water accumulation and weight gain)
- Hail weather: Cover the bracket joints with protective pads in advance
Safety tips: Do not perform outdoor maintenance in thunderstorms
Part 3:Solutions to common problems
3.1 What to do if the bracket is rusted?
Three-step treatment method:
- Use sandpaper to polish the rusted parts
- Apply special anti-rust paste (available at hardware stores)
- Spray anti-rust paint of similar color
Note: If the rust area exceeds 10%, you need to contact professionals
3.2 How to repair the shaking bracket?
Three steps of self-check:
- Check whether the foundation bolts are loose
- Check whether the support rods are deformed
- Test the connection firmness of adjacent brackets
The ultimate trick for users
It is recommended to do professional maintenance every 3 years (the cost is about 2% of the whole system). With daily maintenance, the actual service life of the bracket with a 25-year warranty period can be extended to more than 30 years. Remember, every investment in bracket maintenance will be returned to you through continuous and stable power generation income!
