Solar power is gradually replacing the energy consumption pattern worldwide. More people across the world are becoming more aware of their surrounding environment. With global temperatures soaring alarmingly, solar panels have become an investment source as well.  

Solar power is renewable, the panels last for more than 20 years, and the process does not add to the carbon emission problem. 

Once you install the solar panel spending a substantial amount, you can be sure of reaping at least 15-20% ROI in terms of lower electricity bills, fewer power supply disruptions, and lighter carbon footprints. 

However, India has yet not started to invest in solar panels significantly. As a tropical country, India receives 5000 Trillion kWh of energy annually. Most parts of India remain flooded with bright sunlight for most of the time in a year. But, India uses only a fraction of this available energy for power generation. In 2023, the country generated 72 billion kWh of solar energy, which is way less than its full potential.

On the other hand, India is emerging as a major solar equipment exporter in global trade. In 2023-24 FY, the country registered a staggering 364% growth in this sector (Source). Therefore, undoubtedly, the global demand for solar power is soaring high.

Common Problems with Solar Panels

1. Inverter Troubles

The solar panels trap the solar energy to generate DC electricity. But, to run appliances like fans, lights, refrigerators, etc., AC electricity is necessary. Here comes the role of the inverter that converts the DC electricity into an AC electric to keep the appliances solar-run.

So, technically, without an optimally working inverter, solar panels alone do not mean anything. Since inverters are indispensable for solar panels to work usefully, a malfunctioning inverter can be a threat to the entire solar power arrangement. 

While solar panels remain perfectly efficient for almost two decades, the lifetime of the inverters remains only 10 years. Moreover, malfunctioning inverters can be a source of multiple electric hazards.  Therefore, inverter troubles can be threatening to the safety of the premises using solar energy. 

However, handling this issue is not a difficult task. You just have to be watchful if the inverter is working fine. If you find any problems in it, call the technicians to get it fixed or replaced. 

2. Roof Damage

In places where open areas are hard to find, installing solar panels can be challenging. It is always best to install these heavy setups on the ground. But, if your house does not have such an elaborate space, installing the panels on the rooftop remains the only choice.

Undoubtedly, rooftops receive unhindered sunlight for a major period every day. Therefore the amount of electricity generated by the panel should be higher on rooftops. But, at the same time, this installation can be threatening to the roof itself. 

Expert technicians install the panels carefully but firmly on the roof’s flooring. If the underlying materials are resilient enough, they withstand the hazard. But, in many cases, the roof floor undergoes wear and tear and severe damage due to such installations. 

The easiest way to keep the chances of any accidents due to fragile rooftops would be to check the roof surface regularly. If you notice any crack or damaged shingle or tile, call the expert to get them repaired or replaced. 

3. PID Effect

PID refers to Potential Induced Degradation. This condition is quite common for solar panels. Ideally, the surface level of the solar panels should remain passive or uncharged. Under PID, the solar panel surface gradually begins to gather electric charges. 

Consequently, the battery surface’s passivation effect aggravates and the fill factor goes down. Following this process, the open circuit voltage also reduces. Finally, the panel runs the risk of a short circuit that often leads to fire and severe damage.  

PID is a technical fault that only expert technicians can remedy. The primary reason for solar panels to experience PID effects remains faulty installation. This is why hiring professionals for the solar panel installation task in the first place is necessary. 

4. Battery Issues

Solar panels often generate a substantial amount of energy. Especially when the days are clear and sunny, the amount of power generated by these panels can exceed your daily requirement significantly. 

This is when storing the extra energy becomes necessary. Keeping this requirement in mind, the panels either remain connected with grids or batteries. Both grids and batteries act as the storage house of additional electricity generated by the panels. 

If any solar panel is off-grid, batteries store the extra power. Now, the batteries might undergo numerous problems such as undercharging, overcharging, sulfation, etc. In the case of such issues, the batteries malfunction and cause problems like fire, power loss, etc. 

This is a common problem for solar panels attached to batteries for power conservation. To avoid such circumstances, you can get the batteries checked regularly. This will ensure the safety of your solar panels, and the solar run appliances.

5. Snail Trail

It is a well-known fact that solar energy enters the panels’ cells through the solar panel’s surface. This is why experts always recommend installing the panels in a place where there would be no shade or barrier between the sun and the panel. 

Since the solar panels stand on open areas like gardens, backyards, or rooftops, snails often walk across the panel’s surface. This leaves a thin layer of muddy trail on it. 

One or two such trails do not impede the power generation capacity of the panels significantly. But, when multiple snail trails crisscross each across the panel’s surface, it gets coated with a thin layer of mud. Consequently, the power generation efficiency of the panel goes down. A clear surface is essential for optimal sunlight absorption. 

With muddy layers covering the surface, the panel’s solar power absorption capacity reduces and it generates less power. 

6. Hot Spots

Solar panel installation involves intense wiring arrangements. If the panel installation work is done flawlessly, half of the common solar panel problems will never appear. However, hot spot remains an issue that emerges due to faulty wiring systems. 

In the case of crippled wires, the problems of overloading, inefficient soldering, and distorted cell structures may arise. All these conditions may lead to the generation of excessive heat. As a result, there can be fire and electricity outages. 

This can be a risky situation for any premise using solar power. However, avoiding this problem is not difficult. You just have to be sure of hiring experienced and professional solar panel installation experts.  If the installation is flawless, hot spot problems generally do not arise.

7. Panel’s Efficiency Issues

There can be several reasons for the solar panel to work inefficiently. One of the causes can be a faulty installation. If the solar panel sits under a tree or in a shady area, the sunlight exposure would be less. Solar panels work at their best capacity only when the sunlight exposure is optimum. Hence inefficiency creeps in. 

Additionally, not cleaning the panel surface can be another source for the panel’s efficiency. Especially if it has been windy for the last few days or there was a storm last week, your solar panel surface is likely to get covered with a dust layer.  

Dust layers reduce the panel’s capacity to absorb sunlight. So, even if your panel is standing in an open space inundated with bright sunlight, the power generation would be slow and low. 

Overcoming these problems is simple. You just have to make sure to install the panels properly engaging experts. The professionals would know the best place where the panels can get the maximum sunlight exposure. 

To avoid dust accumulation on the panel surface, get the panels cleaned regularly. Therefore, a little awareness and maintenance are all your panels need to work efficiently. 

8. Cost Issues

Inarguably, solar power is one of the best alternatives for power generation without damaging the environment severely. But, the initial cost of installing the setup can be substantial. 

This is one of the reasons many people hesitate to use solar power even though they understand the perils of exhausting non-renewable resources. 

Plus, regular maintenance is also necessary to keep the power generation capacity of the panels intact.  This adds to the overall cost. 

However, with research and development, in the future, the cost of solar panels might go down. But, if you calculate the long-run cost of the panels, the prices would appear to be reasonable rather than excessive. Solar-powered appliances do not add to the electricity consumption bills. 

Therefore, solar power users pay less for electricity consumption than those who rely only on non-solar energy. 

Final Words

Unquestionably, solar panels come with multiple common problems. But, most of these issues can be resolved without much ado. To begin with, installing the panels carefully and flawlessly solves more than half of the problems. 

In case of more complex problems, you can always seek the help of professionals and experts. Since solar panels reduce the carbon footprints of this plant substantially; giving it a shot would be the right thing to do. Also, by using solar-powered appliances, you can cut down on your electricity bills significantly.
