What are the benefits to cleaning solar panels?

Cleaning solar panels provides several benefits, including:

  1. Increased Efficiency: Removing dirt, dust, and debris allows more sunlight to reach the solar cells, improving energy production and overall system efficiency.

  2. Maximized Energy Output: Clean solar panels generate more power, leading to increased energy output and better performance of your solar installation.

  3. Extended Lifespan: Regular cleaning helps prevent long-term damage, preserving the longevity of your solar panels and protecting your investment.

  4. Enhanced Aesthetics: Clean solar panels contribute to a visually appealing and well-maintained solar array, enhancing the overall look of your property.

  5. Optimal Return on Investment: By maintaining peak performance, cleaning ensures you get the most out of your solar investment and potentially reduces maintenance costs over time.

Will rain clean solar panels?

A similar question to ask is, does rain wash your car? The answer is no, rain alone does not wash your car and in fact, it can leave it dirtier. This is due to rain carrying airborne particles such as dust, pollen, and pollutants. Over time, this accumulation can hinder sunlight absorption and reduce the panels' efficiency, making professional cleaning necessary for optimal performance.

How often should solar panels get cleaned?

In general, it is advisable to clean solar panels at least once or twice a year. However, in areas with high pollution, dust, or bird activity, more frequent cleaning may be beneficial to maintain optimal efficiency. Regular inspections can help determine the appropriate cleaning schedule for your specific circumstances.

Why is it important to clean out rain gutters?

Cleaning out rain gutters is important to ensure proper water drainage and to prevent issues that may create further damage. Some issues that may occur include water damage to the roof, siding, and foundation. Clogged gutters can lead to water overflow, leaks, and potential structural damage to the property. Regular gutter cleaning helps maintain the integrity of the home's exterior and prevents costly repairs by allowing rainwater to flow freely away from your home.

When is the best time to get rain gutters cleaned?

The best time to get your rain gutters cleaned is typically during the fall and spring seasons, preferably before it starts raining. Cleaning them in the fall removes accumulated leaves, while spring cleaning addresses any debris from winter storms. Regular maintenance during these seasons helps prevent clogs, water damage and ensures optimal performance of your gutter system. Ensure the optimal performance of your gutter system by scheduling a cleaning before the rainy season begins.

How often should rain gutters get cleaned?

Rain gutters should be cleaned at least twice a year, typically in the fall and spring. However, in areas with heavy foliage, frequent storms, or increased debris, more frequent cleaning may be necessary. Regular inspections can help determine the specific cleaning schedule required for optimal gutter maintenance.

Guards

What are critter guards?

Critter guards are a protective device that runs along the perimeter of solar panel arrays. They are designed to prevent wildlife, such as birds and rodents, from accessing the space beneath solar panels. These guards create a barrier, preventing animals from nesting, causing damage, or disrupting the functionality of solar panel installations.

Why are critter guards important to install?

Critters, such as birds and rodents, are attracted to the space under solar panels because it provides shelter and protection. The area offers a secluded and warm environment, making it an ideal location for nesting and seeking refuge from predators. Unfortunately, their presence under solar panels can lead to potential damage to wiring and components, emphasizing the importance of critter guards to prevent such issues.

What material is used for the critter guards. 

DND Solar Panel Cleaning Services uses PVC-covered wire mesh for the critter guard installation. PVC coating adds an extra layer of protection against corrosion and extends the lifespan of the mesh. Additionally, the mesh structure effectively creates a barrier, preventing critters from accessing the space beneath solar panels while allowing for proper ventilation. This makes PVC-wired mesh a practical and long-lasting solution for critter guard installations. Additionally, the critter guard materials used by DND Solar Panel Services are pre-cut to fit all roof styles and types.
