With the progress of science and technology, more and more people will look to green energy such as photovoltaic, photovoltaic building integration concept is also gradually penetrated into the hearts of the people, as a homeowner, the aesthetics of the building is a very important point, so many of them will choose to install the best solar roof tiles on the roof, the roof tiles and photovoltaic perfect combination of the achievements of the integrated solar The perfect combination of roof tiles and photovoltaics has resulted in integrated solar roof tiles, which not only capture the sun's energy but also maintain the integrity of the roof.

The failure and maintenance of solar roof tiles requires special attention. Since solar roof tiles are small in size, it takes a large number of tiles to cover the roof, solar roof tiles are connected to solar roof tiles, a certain number of solar roof tiles are connected to form a small whole, and there are a variable number of small wholes on the roof, plus each roof is different, the installation of solar roof tiles is not the same. The situation of each roof is different, and the installation and connection methods are also different. Therefore, once a certain piece of solar roof tiles fails, how to find it out is a very difficult thing.

But don't worry, as a professional manufacturer of best solar roof tiles, we not only know our products very well, we have completed many solar roof tiles projects and are responsible for the subsequent operation and maintenance, we not only know our products very well, but also have a lot of experience.

So please be patient and read this technical article so you can learn how to operate and prepare for your pv tiles roof maintenance in advance.

When yoursolar roof fails, it is imperative that you need to determine exactly what is wrong with that tile, then you will need a combination of visual inspection, performance monitoring, infrared thermography and electrical testing. Please don't worry, here are the top five detailed steps:

1. Visual inspection

VISUAL INSPECTION: Periodically inspect the surface of solar roof tiles shingles for visible damage, cracks, discoloration, or shading. If any of the tiles look different from the others, it may be a sign of damage.

Regular surface cleaning: Make sure the surface of solar roof tiles is clean to make it easier to spot any physical damage, noting that solar roof tiles need to be kept out of shaded areas, such as under trees.

2. Performance monitoring

Monitoring system: Use the monitoring system that comes with the solar roof tiles system to view real-time power generation data for each tile or module.

Data analysis: Compare the power generation of each tile. If the power generation of one tile is significantly lower than that of other tiles, it may indicate a problem with that tile.

3. Infrared Thermal Imaging

Thermal imaging equipment: Use infrared thermal imaging cameras to scan solar roof tiles and detect the temperature distribution of the tiles.

Hot Spot Identification: Damaged solar roof tiles typically exhibit areas of abnormally high temperatures, known as hot spots. Thermal imaging can quickly locate these abnormal areas.

4. Electrical Testing

Open-circuit voltage test: Use a multimeter or special PV tester to measure the open-circuit voltage of each tile. If a tile's voltage is significantly lower than normal, there may be a problem.

Short-circuit current test: Measure the short-circuit current of each tile. Similarly, if the current value of a tile is abnormal, it may indicate that the tile is faulty.

5. Current-Voltage (I-V) Curve Analysis

I-V Tester: Test the solar roof tiles with an I-V curve tester and plot the current-voltage curve for each tile.

Comparison of curves: Normal tiles should have smooth I-V curves. If a tile has an abnormal I-V curve, it may indicate a problem with that tile.

Step Summary

Perform a visual inspection to look for obvious physical damage and obscurations.

Detect real-time power generation data for each tile through monitoring systems and data analytics.

Using infrared thermography, scan solar roof tiles to identify tiles with abnormal temperatures.

Perform electrical tests to measure open circuit voltage and short circuit current to identify abnormal tiles.

Perform detailed current-voltage characterization of tiles using an I-V curve tester.

Precautions

Safe operation: Ensure that safety protocols are followed to avoid the risk of electric shock when performing any electrical tests.

Specialized equipment: Infrared thermography and I-V testing require specialized equipment and technicians to operate.

Timely Repair: Once a damaged tile is found, it should be replaced or repaired in a timely manner to avoid affecting the overall system performance.

Through these methods, damaged solar roof tiles tiles can be effectively detected to ensure the efficient operation and long-term reliability of the solar roof tiles system.

Roofs are an important part of homes and buildings, so it is recommended that homeowners regularly clean and check and observe the power generation data to be able to detect and fix small faults at the beginning of the process and repair them before they cause major damage, as we all know, prevention is better than remediation, which is the most cost-effective way to do it.
