C&I Commercial and Industrial Solar Panel Cleaning

Solar panels are a great way to conserve energy and save on your electric bill, but many people don’t realize that they need to be cleaned to perform at peak efficiency. Leaves, bird droppings, and atmospheric airborne particles (dirt, pollen, road salt, any airborne debris particles) all have the potential to build up on your solar panels – and dirty solar panels means – power loss. Grime and debris reduce the ability of the solar array to perform at full capacity, making your solar panel system less efficient. A solar array comprises several solar modules wired together, and each solar module is made up of solar cells, all mounted collectively in a frame. Solar cells, in turn, are made of semiconductor materials, such as silica. One side of a solar cell is positive, the other negative. When sunlight hits a solar cell, it excites the electrons in the semiconductor material, and it’s this energy that can be captured as electricity. If the cells aren’t clean, electrons do not get as excited, and less sunlight is able to be absorbed, hence producing less electricity. That is why C&I Commercial and Industrial Solar Panel Cleaning is so important.

The potential energy loss depends on the level of soil your solar panels have accumulated. Energy loss could reach as much as 25%. Some reports even bring the number as high as 30% for consumers who never clean their system. We also offer residential solar panel cleaning.

Optimize Your Solar Panels

When sunlight hits solar photovoltaic (PV) panels, they convert the sun’s energy into clean solar electricity for homes, businesses, and communities. More sunshine means more electricity

However, this is only part of the equation.

The goal is to optimize the amount of sunshine reaching the solar panels. Professional installers factor this in when positioning and orienting PV modules. But maximizing sun capture also requires keeping the panels free of dust, leaves, snow, and other debris. Difficult to ignore one’s own experience – like how leaving a dirty car out in the rain doesn’t automatically make it clean. In fact, carwashes are often busiest right after a heavy storm. Don’t ignore Industrial & Commercial Solar Panel Cleaning.


Installing solar panels on your home offers a range of benefits, from enjoying a renewable energy source that keeps bills down to doing your part towards reducing emissions. In fact, many solar panels pay for themselves over time with all the savings they offer!

However, there are some things to consider when investing in solar panels. One of the most overlooked aspects of owning solar panels is factors of nature. Many naturally occurring factors – from the weather to local wildlife – can impact the effectiveness of your solar panels. Book now.

1. Soiling

Perhaps one of the most common issues when it comes to solar panel efficiency is soiling. This takes many forms, including dirt, dust, snow, and any other particles that may cover the surface area of the panel.

Dust and dirt are some of the worst offenders as they can be less obvious but still reduce the overall effectiveness of your solar panels. The worst soiling tends to be based on the climate of the area, such as snowy climates that use a lot of road salts, coastal areas, agricultural areas, and dry sandy regions that suffer from high dust pollution.

2. Pests

Two of the biggest pests that reduce the effectiveness of your solar panels are birds (such as pigeons) and squirrels. For instance, pigeons are attracted to solar panels as they are great nesting places, meaning you could end up with several pigeons interfering with your solar panels.

They leave a lot of droppings behind, much of which may cover your panels. As mentioned before, soiling can reduce the effectiveness significantly, making pigeons and their nests a real nuisance.

Similarly, squirrels have a natural tendency to chew, so they are often attracted to the wires of solar panels, causing damage that reduces their effectiveness.

3. Shade

Not everyone is aware of the risks of installing their solar panels in areas that are shaded for portions of the day, but they are significant. The main issue is that shade causes individual solar panels to switch off, resulting in the switched-on panels working extra hard to compensate for the lost energy.

This usually leads to overheating of the unshaded panels, meaning any number of panels can stop working, greatly reducing their effectiveness. Even if the shade doesn’t lead to overheating in the panels, it still means they don’t work when covered, reducing their effectiveness.

4. Reduced Sun

If solar panels are non-tracking (i.e., they don’t follow the movement of the sun) it means they stand to lose effectiveness at certain portions of the day throughout the year. For instance, homes in North America with fixed solar panels should always be south facing to get as much sunlight as possible during the day.

Furthermore, it’s a good idea to adjust the position slightly twice each year to accommodate the sun’s changed position. The sun sits much higher in the sky during the summer while passing the sky at lower angles during the winter, which can reduce the effectiveness of the panels if not positioned optimally.
