When do Your Solar Panels Need Repair or Replacement

 

"Every second our Sun produces enough energy to sustain Earth's needs for 500,000 years. How do we harness this power?"

Solar panels are built to last, but there are certain instances where it causes a halt in producing optimised amounts of electricity. There are several reasons why your solar panels need replacement or repair. If your solar panels were installed decades ago and their performance is deteriorating. In that case, you must seek the advice of a professional solar panel repair and maintenance service provider. In today's blog, we have covered the reasons that suggest that your solar panels need either repair or replacement.             

Signs or Factors that Suggest PV Repair or Replacement:

• Irregular or Low Power Output

One of the best ways to measure the performance of a solar system is by its output and comparing it to the panel's nominal rating and stated specifications. But how to measure it, right? Ensure to set the multimeter at least at 10 amp scale at noon on a sunny day with 25 degrees to get the best result.

If the current voltage is less than 80% of the specified output, it indicates that the solar panels are wearing out and need to be replaced soon. According to a study, the production of solar panels is likely to reduce by 0.5% per year, which means even in the 20th year of use, it is capable of producing approximately 90% of the electricity produced in the first year. Anything less than directly indicates the system replacement. 

   

• Solar Panels Age Matters

The quote "age is just a number" won't be true in the case of materialistic things like solar panels, as it does matter a lot when it comes to output optimization. It is generally considered that solar panels can optimally work for 20 to 30 years. But beyond this, they start to deteriorate in performance due to the photovoltaic silicon material of solar panels. But if the output is poorly low, then you must replace the panels with new ones. You can contact the solar PV repair service provider to understand the solution in a better way. 

• Counterfeit Panels

In order to earn extra money, some manufacturers use counterfeit cell conductors with genuine ones to cut the overall cost. The counterfeit cell conductors cannot perform well, resulting in low output, less solar absorption, and hence more electricity bills. You can contact solar panel specialists like Solar Daddy, who can recognize such parts and help save you a lot of time and money. 

• Physical Deterioration

There are multiple reasons and causes for solar panels' physical damage. Wind, hail, delamination, corrosion, broken interconnects, debris, and other objects play a vital role in the deteriorating physical condition of the panels. The majority of solar panels use durable tempered glass, which increases the chances of damage to manifolds. 

For example, a big stone or objects from a tornado can crack the panel body to a great extent. Cracked glasses are very dangerous as the water gets seeped into solar panel cells, which causes further damage. In such a situation, you should call the solar PV repair service provider to check if it needs replacement or repair will do the work.                               

• Discolouration of Panels' Surface

Solar panel discolouration is visible as brown and yellow pigmentation develops on the panels. It results from the uncontrollable chemical reaction from materials within the panels. Sometimes when poor-quality raw materials are used in the panels, it results in the brown pigmentation of the surface.

Discolouration not only disturbs the overall look of the panels but also reduces the panel performance to a great level. Generally, discolouration happens after several years of installation due to any of the reasons mentioned above. 

• Broken Glasses 

Solar panel glasses can be broken for several reasons, from debris, tree branches, stone or sharp objects from any natural calamities, and much more. A major issue with broken glasses is that solar cells are no longer protected from moisture, and they often fall out from time to time which can further cause any accidents. It can still produce high voltage, but it can suddenly stop working when they are exposed to harmful elements. In such a scenario, call the solar panel repair and maintenance service provider in order to repair the panels quickly.

 

• Unpredicted Shutdowns

One of the common signs that indicate your solar panels' replacement or repair is unpredicted shutdowns. Several reasons for the system's unexpected shutdown include panels' manufacturing defects, wiring problems, faulty installation, and many more. Do not wait for several shutdowns, as it can cause huge losses. Contact solar panel repair and maintenance services to get the system diagnoses at the earliest.

 

• Output is Slumping

There are several reasons why solar panels are not performing well, especially during the rainy and winter season, but if it is not performing well on sunny days, then it is a big problem. Before jumping to any conclusion, ensure that panels are free from debris and, if not, clean them with a hose. Even if it does not produce the desired result, you need to call solar panel repair and maintenance services.
