Why Are My Solar Panels Not Producing Enough Power

Why are solar panels not producing enough power? Solar panel owners who monitor their systems and check their power bills regularly might notice a drop in their system’s output. If you suddenly see a high energy bill after enjoying months or even years of savings, you might start to wonder, “What’s going on with my system?”

While a jump in energy costs can sometimes be due to things like using the air conditioner a lot during a heatwave, a decrease in energy production could signal a problem with your solar panels or other parts of your setup. Before deciding that your solar system isn’t doing its job properly, it’s a good idea to think about a few things.

You might be seeing less solar energy being produced. Here are some reasons this could be happening and how you can get your system back on track.

Many Solar Installations Come With 24/7 System Monitoring

If you get a higher-than-usual energy bill, first, check your solar monitoring app. It should show you how much energy your system has been putting out over time. Compare the energy production for the current month with the same time last year. Look at how much energy your system has been making.

If you don’t have data from years, just check the past few months. Normally, as we move into summer, your system should make more energy. As fall and winter come around, it should make less. Usually, these changes happen smoothly. But if you see a sudden drop in production, it’s time to figure out why.

Factors Affecting Solar Power Production

Cloudy weather, unusually high energy demand, and other variables may be the cause of your solar panels producing not enough power.

Take a look at the recent weather patterns. Have there been a lot of cloudy days? You can check monthly weather summaries online by searching for your city and “30-day weather forecast.” Cloudy weather can reduce your solar system‘s energy production.

Think about how much electricity you’ve been using. There’s plenty of sunlight in summer, but high temperatures might mean you’re using the air conditioner a lot. This could lead to higher energy consumption, surpassing what your solar panels can generate. You might rely more on grid energy than usual.

Air conditioning is just one example. Sometimes, your home might need more energy than your solar system can provide. For instance, when you get home from work in the evening and start using appliances as the sun sets, you’ll need grid energy because solar panels don’t work in the dark. Plus, during these evening hours, energy prices from the grid are often highest, leading to a bigger bill than expected.

Another reason why your solar panels are not producing enough power is maybe your solar system could also be dirty. They’re made of photovoltaic cells covered with a thin layer of glass. If they’re covered in dirt, leaves, bird droppings, or other debris, they won’t convert sunlight efficiently. You can clean them with a brush or by spraying them with water from a garden hose. If you’re unsure, contact your solar installation company for help.

Battery Systems Have Limited Storage Capacity

Battery storage systems for your home can lessen your reliance on the grid, but they’re not meant to keep your house running forever.

Most home battery systems are designed to handle only part of your home’s needs. They’re there to power essential appliances when your solar panels can’t generate enough energy. But none of them can handle your whole house.

If you only rely on your battery system, you’ll probably end up using grid electricity within an hour or so. That doesn’t mean your solar battery isn’t doing its job. It’s just that most people can’t afford a battery system big enough to power their entire home for hours on end.

Your Solar System Might Need Professional Repair

If you’ve tried everything else and you’re still worried about your system’s energy production, you can rely on the warranty. Get in touch with the company that sold or financed your system. If repairs are needed, the warranty should cover both the parts and the labor.

Sometimes, homeowners with older solar systems might find that the company that sold it has closed down. In that case, reach out to the manufacturer of the solar system. The warranty should still be valid, but the manufacturer will handle replacements for defective parts, while you’ll need to cover the labor.

Solar systems are built to be efficient and dependable. If you notice a big drop in energy production, it’s important to figure out why. Usually, it’s because of things like bad weather. But if you think your system might be broken, contact the company you bought it from. Your warranty should take care of any needed replacements and repairs.
