Top Commercial Solar Maintenance Tips to Protect Your Investment

Is your commercial solar system maximizing its performance? As a business owner who has invested in solar energy (like many people), you already know that the potential for harnessing renewable energy is incredible. More specifically, the National Renewable Energy Laboratory (NREL) reported that solar panels typically last 25 to 30 years. Sustaining their performance one year after another requires ongoing maintenance and strategic care. As we know, commercial solar solutions will mainly require low maintenance, but the efficiency of your system can fall without regular maintenance.

In this blog, we’ll discuss key commercial solar maintenance tips that safeguard your investment and guarantee your system functions at its best. These strategies, including routine cleaning and monitoring your energy output, will save you money, prolong your system’s lifespan, and ensure a great return on your investment. Read on for more information on how the experts at Solar Medix can help you maintain optimal solar system performance!

Why Commercial Solar Maintenance Matters

Why Commercial Solar Maintenance Matters
The adoption rate of solar energy among companies worldwide is increasing sharply. In fact, the U.S. commercial solar market grew 8.6 GWdc of capacity in 2024 alone, according to the Solar Energy Industries Association (SEIA). This trend indicates an increased awareness that solar energy reduces energy costs and is a key factor in reducing a company’s carbon footprint. However, purchasing a commercial solar system is only the first step. A regular maintenance program will be the key to keeping the system working as long as possible to the best of its ability.

The Investment Tax Credit (ITC) for solar installations was enhanced by the Inflation Reduction Act (IRA) of 2022. Previously, companies could take a 26% tax credit for 2022, dropping to 22% for 2023. After the IRA, the ITC was raised to 30% in 2022 and then held at that rate through 2032 to drive more investment in solar technologies. (Geoscape Solar)

The market for the IRA’s transferable tax credit system has helped to create a surge of investment in solar and other clean energy technologies. Also, for the first time, developers can take investment tax credits (ITCs) and production tax credits (PTCs) up to 60% of project costs as a financial incentive to make solar projects a cash cow.

Solar systems have a longer lifetime, but improper maintenance can dramatically reduce system efficiency, resulting in wasted energy and loss in savings. Your business has critical equipment, and just as you wouldn’t neglect any of this equipment, your solar panels also deserve routine care. Routine maintenance keeps your system running smoothly, allowing your business to continue reaping clean energy’s financial and environmental benefits.

5 Key Challenges in Commercial Solar System Maintenance

Solar panels face some key challenges over time, even though these energy systems have low maintenance requirements. Promptly tackling such issues can avoid major system breakdowns and the accompanying costs.

Here are five maintenance challenges you’re often up against:

1. Dust and Debris Accumulation
2. Weather Damage
3. Electrical Component Failures
4. Performance Degradation
5. Undetected System Faults

1. Dust and Debris Accumulation

• Solar panels can become dirty from dust, leaves, pollen, and other debris. Over time, this buildup can coat the panels’ surface, blocking sunlight and reducing energy efficiency.
• If they are not properly cleaned, dust accumulation can drop the efficiency of your panels by 20-30%. (energy. gov)

2. Weather Damage

• Severe weather conditions such as hailstorms, heavy snow, and high winds can physically damage your solar panels or racking systems.
• Commercial solar systems may require frequent inspections in storm-heavy regions to determine how weather events affect their performance.

3. Electrical Component Failures

• Some parts, such as inverters and wiring, are necessary for the solar panels to work correctly. Electrical components can degrade over time, resulting in degraded performance or total system failure.
• The inverters, in particular, are vulnerable and often must be replaced every 10 to 15 years to keep the system up and running correctly. (solarreviews.com)

4. Performance Degradation

• Solar panels deteriorate gradually (an average of about 0.5% annual inefficiency), but even minor degradation builds up over the years.
• Regular monitoring and maintenance can also catch drops in performance early on, allowing quick action to return to optimal function.

5. Undetected System Faults

• Seemingly harmless problems like loose connections or failing wiring often go unnoticed until they become more intense.
• Routine system checks and monitoring can help detect these faults before they escalate into larger, more costly repairs.

Top 5 Commercial Solar Maintenance Tips
