Solar Maintenance 101: Cleaning Panels – How and When To Do It

As India moves towards adopting solar energy at the industrial, institutional, and residential levels, a dirty solar panel remains one of the often overlooked but critical factors hindering solar efficiency.

We assume that every solar installation will provide cost-effective, clean energy right from the start. While that expectation is mostly true, there is one critical “if” that must be emphasized: solar panels require proactive maintenance and thorough cleaning to deliver optimum results. In reality, a mere thin layer of dust, or even bird droppings, can lead to a reduction of 10 to 25 percent in power generation.

In India’s context, the environment is particularly dry, dusty, and polluted. Untainted solar panels lead to sustained underperformance and additional losses.

🌫️ Why the Neglection of Maintenance is Important

Solar panels require direct exposure to sunlight to convert it into usable electricity. Anything that comes from the urban dust, industrial smog, leaves, and even animal excreta restricts the inflow of solar radiation will result in reduced panel absorption and therefore, output.

It might not look like much at first glance, but the following losses steadily accumulate over time:

📉 Energy production decreases.

💡 Increased operational costs due to an energy deficit.

⚠️ Increased wear and tear on critical systems leading to increased likelihood of failure.

🧾 Decreased ROI and extended recapture time.

💰 Avoidable costs due to premature maintenance or replacement.

Ultimately, the financial loss incurred due to inadequate maintenance of a solar system can, and will, exceed the expected value, thus negating the intent of installation.

🔍 What is the Frequency of Cleaning Your Solar Panels:

As previously mentioned, not every case is the same. Solar panel systems are personalized to the client’s specifications and needs; therefore, geographical location, system size, and dust or pollution exposure are determining factors guiding maintenance. A summarized guide includes:

• Urban & Industrial Areas
  Due to higher pollution, traffic, and soot, cleaning is required bi-weekly to monthly.
• Rural or Low Dust Areas
  Maintenance is needed every 6 to 8 weeks. This is influenced by green vegetation, bird activity, and seasonal weather.
• Corporate Rooftops and Solar Farms
  These need routine scheduled professional maintenance, especially in dry and windy months.

⏰ Keep in Mind: Losing in excess of 1 month of cleaning translates to a lot of inefficiency and lose in funds, to greater expense.

🧼 Methods of Cleaning: Robotic and Manual Cleaning

✔️ Manual Cleaning
These are ideal for smaller systems found in households, schools, and offices.
Method: Gentle brushes, pure water, and non-abrasive cloths can be used.
Avoid hard water, overuse of chemicals, or power scrubbing as they can chip or scratch the glass.

🤖 Robotic Cleaning
Best suited for large scale ground mounted solar plants or industrial setups.
Method: Soften rotating brushes and controlled water spray are incorporated through automated systems for cleaning hundreds of panels.
It reduces water consumption and the need for manual labor on hot rooftops or hazardous locations.

Note: Tap water, harsh cleaning, or misuse of tools can be damaging through mineral stains and micro cracks.

💡 Real Losses from Dirty Panels: The Math

Some financial statistics:

• The generation of a 100kW system is estimated to yield profits of ₹1.2 lakhs/month.
• With a 20% decline in performance due to dust, the system now reverted to ₹24,000/month in return.
• That totals to ₹2.88 lakhs in a year, all because the panels are not maintained.
• Extrapolate that over five or ten years and it contributes to a staggering total loss.

Amply restoring power and regular maintenance protects the investment, conserving financial impact.
