Weather Impact on Commercial Solar Performance

Solar panels are used across the world to generate electricity from sunlight. Moreso now than ever, we’re seeing an increase in usage for commercial buildings and properties. Needing more electricity means needing to find more efficient and sustainable ways to generate it. Currently, solar energy is the best choice for renewable electricity. It’s easily accessible, eco-friendly, and a great pollution-free source — however, there is a most efficient solar panel usage to follow. Many underestimate the power of solar even in bad weather.

Colorado is friendly with unpredictable weather. From the high altitude to the intense sunshine, intermittent snow, and unexpected winds — solar panels need to be prepped and ready for any kind of inclement weather in Colorado. After all, the goal is to have the most efficient solar panels so they are working for you and not against you. But what does having an efficient solar panel system mean?

Understanding Solar Panel Efficiency

Solar panel efficiency refers to the percentage of sunlight a solar panel can convert into electricity. It’s a measure of how well a solar panel performs in capturing sunlight and generating electricity. While advancements in solar technology have driven efficiency up in recent years, it’s important to understand the factors that can influence a panel’s performance:

• Sunlight: As expected, the amount of direct sunlight a panel receives plays a major role in efficiency. Panels generate the most electricity under clear skies.
• Temperature: Solar panels are semiconductors, and their electrical properties are affected by temperature. While they still operate in cold weather, excessively high temperatures can reduce a panel’s efficiency.
• Shade: Shading on a panel significantly reduces efficiency. Partial shading can impact the entire panel’s output, so it’s vital to consider shading patterns when designing a commercial solar installation.
• Soiling: Dust, dirt, bird droppings, and other debris buildup on a panel can hinder sunlight absorption and reduce efficiency. Regular cleaning is important to maintain optimal performance.

Solar panel efficiency directly impacts the amount of electricity a commercial solar power system generates. Higher-efficiency panels will produce more electricity per square foot, reducing the amount of roof space needed to achieve the desired energy output. This can be especially important for businesses with limited rooftop space.

How Temperature Affects Solar Panel Efficiency

Let’s take a second to talk about one of those factors influencing solar performance: temperature. In Colorado, the temperature is all over the place. In fact, it can be below freezing in the morning and then in the 60s and sunny by the afternoon.

Solar panels are semiconductors, and their electrical properties are affected by temperature. The silicon within a solar panel acts like a conductor when sunlight hits it, allowing electricity to flow. However, as temperatures rise, the silicon atoms in the panel vibrate more intensely, creating resistance to the flow of electricity. This resistance reduces the panel’s efficiency in converting sunlight into electricity.

That’s a lot of fancy language for: the higher the temperature, the less effective solar panels are going to be. But honestly, it’s sometimes only a slight decrease, and in Colorado we’re at an advantage.

A Common Misconception: Solar panel installations don’t perform well in cold-weather climates.

Colorado’s cool temperatures are an advantage for maintaining optimal solar panel output.

That’s right, one of the many benefits of installing commercial solar panels in Colorado is the state’s generally cooler climate. The high altitude, dry air, and cooler operating temperatures allow our state to be one of the best for greater electricity production for businesses.

Solar Panel Performance in Different Weather Conditions

We talked about temperature, but what about the weather?

Sunny Days

Let’s start easy. Colorado gets an average of 300 days of sunshine per year, that makes our state one of the best for solar panel efficiency. You see, sunny days are ideal for solar panel performance. A well-designed and maintained system can generate a significant amount of electricity on a clear, sunny day. For instance, a 10 kW commercial solar system in Denver can be expected to produce around 12,000 to 15,000 kWh of electricity per year.

A Common Misconception: It’s not worth having a solar installation in areas prone to heavy snow.

Snowy Conditions

Snow can actually have a cleansing effect, removing dust and dirt buildup that can impede efficiency. Additionally, snow can reflect sunlight onto the panels, potentially increasing efficiency under certain conditions.

The key to mitigating the impact of snow is proper tilt angle and panel design. We use industry best practices to ensure optimal panel tilt and design for snowmelt and efficient energy production throughout the winter with our clients.

A Common Misconception: Solar panels and wind don’t mix.

Windy Conditions

High winds can pose a challenge for solar panels if they are not securely installed. Strong winds can cause panels to move or even become dislodged, potentially damaging the panels themselves or the roof structure.

However, a professional contractor, like Douglass Colony Group, uses high-quality mounting systems and follows strict installation guidelines to ensure commercial solar panels can withstand Colorado’s wind conditions. Good installation should mean windy conditions are no match for a solar panel system.

Tips for Maximizing Solar Panel Efficiency in Colorado

Regular Cleaning & Maintenance

Dust, dirt, bird droppings, and other debris buildup can reduce efficiency. Regular cleaning, especially following spring snowmelt, is essential to maintain optimal performance. We offer professional cleaning and maintenance services to ensure your commercial solar panels operate at peak efficiency.

Smart Design Choices During Installation

Tilt, positioning, and mounting all play a role in efficiency. Douglass Colony Group’s experienced team designs and installs commercial solar systems to optimize performance for Colorado’s unique climate and weather patterns. Think back to what we talked about regarding wind, sun, and snow.

Monitoring Systems for Performance

Advanced monitoring systems allow you to track your solar system’s performance in real time. You can identify potential issues, optimize energy production, and make informed decisions about your solar investment.

Benefits of Solar Panel Installation for Colorado Businesses

Investing in commercial solar panels offers numerous financial and environmental benefits.

• Energy Production Averages: Commercial solar systems in Colorado can generate significant amounts of electricity. The exact output depends on factors like system size, panel efficiency, and local weather conditions. However, a well-designed system can offset a substantial portion of a business’s energy consumption, ultimately contributing to a business’s sustainability efforts.
• Cost Savings through Energy Independence and Reduced Utility Bills: By generating your own electricity, you can reduce your reliance on traditional utility providers and lower your energy costs. Solar energy is a long-term investment that can provide significant savings over time.
• Federal, State, and Local Incentives for Solar Installations in Colorado: The state of Colorado offers various incentives, including tax credits and rebates, to encourage the adoption of solar energy. Douglass Colony Group can help you navigate these incentives to maximize your savings.
