As businesses increasingly turn to solar energy to reduce costs, improve sustainability, and gain energy independence, commercial onsite solar systems are becoming more popular. Despite their growing adoption, several myths persist about the installation, cost, and benefits of commercial solar. These misconceptions can discourage companies from exploring this clean energy option. In this article, we’ll tackle five of the most common myths about commercial onsite solar and set the record straight.

Myth 1: Solar is Too Expensive for Commercial Businesses

One of the most persistent myths about solar energy is that it’s prohibitively expensive for businesses, especially those with large energy needs. While it’s true that the upfront cost of solar panels and installation can be significant, there are several financial incentives that make solar more affordable than many realize. 

Reality:

The cost of solar technology has dropped significantly over the past decade, making it more accessible to businesses of all sizes.  In fact, many businesses can see a return of investment within four years on a system that can last for up to 25 years, and generate savings of up to 30% on energy bills.

Many solar providers also offer financing options, such as power purchase agreements (PPAs) and leases, which allow businesses to install solar without a large upfront investment. This makes solar a cost-effective option for companies seeking to reduce energy expenses in the long term.

Myth 2: Solar Doesn’t Work in Cloudy or Cold Climates

Some people believe that solar panels only work in sunny climates, but this is far from the truth. The idea that solar panels require constant direct sunlight to generate electricity is a misunderstanding of how solar energy works.

Reality:

Solar panels work by capturing sunlight and converting it into energy, and they don’t require direct sunlight to be effective. In fact, solar panels can still generate electricity on cloudy or overcast days, though they may not be as efficient as they would be in full sun. This is because solar panels are designed to work with diffused sunlight, not just direct sunlight. Even in colder climates, solar panels can function well, as long as there is daylight. Some of the highest-performing solar installations are found in northern regions and even places like Germany, which is known for its cloudy weather.

In colder areas, snow can even benefit solar panels—once it melts off, it can leave behind a clean, reflective surface, boosting energy production. This makes solar a viable option for commercial businesses, regardless of location or climate.

Myth 3: Solar Systems Require too Much Maintenance

A common misconception about solar energy is that it requires constant maintenance and is a hassle to maintain over time. While any electrical system requires some level of attention, the idea that solar systems need frequent repairs is largely exaggerated.

Reality:

Solar panels are low-maintenance and designed to last for decades with minimal upkeep. Most systems require only basic cleaning, typically once or twice a year, to remove dust, dirt, or debris that could block sunlight. In general, rain is often enough to keep the panels clean in many regions.

Furthermore, solar panels have no moving parts, reducing the likelihood of mechanical failure. The inverter, which converts the direct current (DC) electricity from the panels into alternating current (AC) electricity for use in your building, is typically the component that might require maintenance or replacement over time. Modern inverters last anywhere from 10 to 15 years, and solar system warranties usually cover them for a significant period.

Routine inspections every year or two can ensure that the system is functioning optimally. Overall, once the system is installed, solar panels require far less maintenance than many other commercial building systems.  And at PowerGreen, to ensure your solar journey is seamless and efficient we offer quality maintenance, servicing and reporting to optimise the long-term benefits of your solar assets. 

Myth 4: Solar Systems are Only Useful for Large Companies

Many smaller businesses believe that solar energy is only for large corporations with extensive roof space or high energy usage. While large businesses often have the resources to install commercial solar systems, smaller businesses can also benefit from onsite solar energy.

Reality:

Solar energy systems can be scaled to meet the needs of businesses of all sizes. Even small commercial buildings or businesses with limited roof space can install solar panels. Options like solar carports or solar canopies allow businesses to make use of available outdoor space, such as parking lots, to install solar panels without taking up roof space.  And ground mounted solar systems are also a popular choice for businesses or organisations with available outdoor space.

In fact, small and medium-sized businesses are some of the fastest-growing segments adopting solar technology, thanks to flexibility technology, decreasing installation costs, financing options, and long-term savings.

Myth 5: Solar Systems are Difficult to Integrate with Existing Energy Infrastructure

Many businesses worry that installing a solar system will require a complete overhaul of their existing energy infrastructure or be disruptive to their daily operations. The reality is that integrating solar into an existing system is easier and more seamless than many people assume.

Reality:

Solar panel systems can be integrated into your current electrical setup with minimal disruption. Solar energy systems are often connected in conjunction with a battery energy storage system, also known as a BESS system. They work by storing excess electricity generated by solar panels during peak sunlight hours and then during a period of low production the excess energy in the BESS system can be used.

Furthermore, solar systems can often be sized to meet a business’s exact energy needs, ensuring the system produces enough electricity without requiring major changes to the building’s existing infrastructure.

Commercial onsite solar systems are a powerful tool for businesses looking to reduce their energy costs and environmental footprint. Unfortunately, myths and misconceptions continue to prevent many companies from considering solar energy. The reality is that solar is becoming more affordable, accessible, and easy to implement for businesses of all sizes. By debunking these myths, businesses can make informed decisions about adopting solar and take advantage of the many benefits it offers.
