Will Cleaning Solar Panels Help Them Work Better?

Let’s talk about solar panel cleaning in NJ, a rainy and snowy state.

To truly understand why cleaning is so important, let’s dive into the science behind solar panels. Solar panels are made up of photovoltaic (PV) cells, which convert sunlight into electricity. These cells are sensitive to the amount of light they receive. When dust, dirt, or other debris accumulates on the panel’s surface, it creates a barrier that prevents sunlight from reaching the PV cells fully. This reduction in light can significantly decrease the amount of electricity your panels generate.

Imagine your solar panels as a window. A clean window lets in plenty of light, while a dirty one obstructs the view and dims the room. The same principle applies to solar panels. A layer of grime acts like a filter, reducing the sunlight available for energy conversion. This is especially important here in New Jersey, with all the rain and snow throughout the year. As well as the sea spray that accumulates from being close to the ocean. 

Environmental Factors and Their Impact on Solar Panel Cleaning

The rate at which your solar panels get dirty depends on various environmental factors. If you live in an area with high dust levels, frequent bird activity, or nearby trees that shed pollen, your panels will likely require more frequent cleaning. Coastal regions might also experience salt buildup on panels due to sea spray.

Seasonal variations also play a role. Springtime often brings pollen, while summer can be dusty due to dry weather. Even rain isn’t a foolproof solution, as it can leave behind mineral deposits or streaks that affect panel performance. Understanding your local environment and its impact on soiling will help you determine the optimal cleaning schedule for your solar panels.

The Impact of Dirt and Grime on Solar Panels

As mentioned earlier, dirt and grime can significantly affect solar panel performance. Even a thin layer of dust can reduce energy production by a few percentage points. In severe cases, heavily soiled panels might experience efficiency losses of up to 25% or more.

Consider this scenario: if your solar panels are rated to produce 5 kilowatts of power but are operating at 75% efficiency due to dirt buildup, you’re essentially losing 1.25 kilowatts of potential energy. That’s enough to power several household appliances!

The Damage Pests and Animals can do on Solar Panels 

Pests and animals can make solar panels dirty. Birds are a major issue, with their droppings obstructing sunlight and causing corrosion. They often perch on panels and build nests nearby, leaving behind twigs and debris. 

Small animals like squirrels and rodents can also contribute by nesting and leaving dirt, food remnants, and nesting materials. Additionally, these animals might chew on wiring, causing further issues. Insects, although smaller, can leave sticky residues that form a layer of grime on the panels.

How Much Does Cleaning Solar Panels Really Matter?

The impact of dirt on solar panels might seem insignificant at first, but it adds up over time. Even a 5% decrease in efficiency can lead to noticeable reductions in your solar energy generation. In areas with high soiling rates, the losses can be even more significant.

Furthermore, neglecting to clean your panels can lead to long-term consequences. Accumulated dirt can etch into the panel surface, causing permanent damage and reducing its lifespan. Regular cleaning not only boosts energy production but also protects you from needing solar panel repair.

When Should You Clean Your Solar Panels?

There’s no one-size-fits-all answer to solar panel cleaning in NJ, as the ideal cleaning frequency depends on several factors, including:

  • Location: If you live in a dusty or polluted area, more frequent cleaning might be necessary.
  • Panel angle: Panels with a steeper tilt are more likely to shed debris naturally with rain.
  • Weather patterns: Dry seasons or periods with little rainfall can lead to faster soiling.
  • Visible dirt: If you can see a noticeable layer of dirt on your panels, it’s definitely time for a cleaning.

As a general guideline, solar panel cleaning in NJ every six months is a good starting point. However, you might need to adjust this schedule based on your specific circumstances.

How to Clean Your Solar Panels

Cleaning solar panels is a straightforward process that doesn’t require specialized skills or equipment. However, using the right techniques and materials is essential to avoid damaging the panels.

Tools and Materials

  • Soft brush or sponge: Avoid abrasive materials that could scratch the panel surface.
  • Hose with a spray nozzle: A gentle stream of water is usually sufficient.
  • Squeegee or soft cloth: Use this to wipe away excess water and prevent streaks.
  • Mild detergent (optional): If the dirt is stubborn, a mild detergent mixed with water can be used.

Cleaning Steps

  1. Choose the right time: The best time to clean is early morning or late afternoon when the panels are cooler. Cleaning hot panels can cause thermal shock and potential damage.
  2. Rinse with water: Start by rinsing the panels with a gentle stream of water to remove loose debris.
  3. Apply detergent (optional): If needed, apply a mild detergent solution and gently scrub with a soft brush or sponge.
  4. Rinse thoroughly: Rinse off all detergent residue with water.
  5. Dry the panels: Use a squeegee or soft cloth to wipe away excess water and prevent water spots.

Professional Cleaning vs. DIY

While solar panel cleaning in NJ all yourself is feasible, there are situations where professional cleaning might be a better option:

  • Hard-to-reach panels: If your panels are installed on a high roof or in a difficult-to-access location.
  • Extensive soiling: If your panels are heavily soiled or have stubborn stains that don’t come off with DIY methods, professionals have access to specialized cleaning solutions and techniques.
  • Limited time or mobility: If you’re short on time or have physical limitations that make it difficult to clean the panels yourself, professional cleaning can be a convenient solution.
  • Safety Concerns: It’s safer to hire professionals who have the equipment and experience to handle the job safely.
