Tips to Clean Solar Panels

Tips to Clean Solar Panels - In today's society, the move to clean energy is no longer an option; It is a necessity! Solar panels, with their ability to capture the sun's energy and convert it into electricity, have emerged as a major player in this transformation. Whether you've recently installed solar panels on your roof or have been using them for a while, it's important to maintain them, especially keeping them clean. Clean solar panels can have a huge impact on their efficiency and, as a result, your energy savings. In today's article from TDG Solar, we will discuss Tips to Clean Solar Panels and the need to keep solar panels clean.

Tips to Clean Solar Panels

Why does cleaning solar panels matter?

Solar panels are intended to be long-lasting and low-maintenance, although they are not completely maintenance-free. Over time, dust, dirt, bird droppings, pollen, leaves, and other debris can accumulate on the surface of solar panels. When these impurities accumulate, they create a barrier between the sun's rays and the solar cells, limiting the effectiveness of the panels. Here's why it's important to keep your solar panels clean:

Enhanced Efficiency - Clean solar panels absorb more sunlight, resulting in more electricity production. Dirty panels can lose up to 25% of their performance, which will have a direct impact on your energy savings.

Prolonged Lifespan  - Regular cleaning can help your solar panels last longer. Dirt and grime can cause rust and damage to the appliance over time, reducing its operating lifespan.

Optimized ROI - Solar panels are an expensive investment. By keeping them clean, you can get the maximum return on your investment by improving their energy output. 

Tips to Clean Solar Panels for a Greener Future

Regular Visual Inspections

Start by performing frequent visual inspections of your solar panels. You can identify any obvious dirt, debris, or damage by carefully inspecting it. Keep an eye out for bird droppings, fallen leaves, and dust accumulation. Early detection allows you to resolve problems before they affect panel performance.

Safety First

Prioritize safety before starting the cleaning process. If you're cleaning ceiling panels, make sure you have the necessary safety equipment, such as a safe ladder, non-slip shoes, and a safety harness. On hot days, be careful around hot surfaces, as the solar panels may scorch.

Choose the Right Time

Cleaning your solar panels at the appropriate time can make a big difference. Clean the panels early in the morning or late in the evening when they have cooled. When cleaning hot panels, water evaporates rapidly, leaving behind streaks and residue.

Use Clean Water

Water is the most effective cleaning agent for solar panels. Wash away dirt and debris with clean, mild water. Hard water with high mineral content can leave mineral deposits on the panels, limiting their efficiency. If your water is hard, consider using deionized water or a water softener.

Gentle cleaning tools

Avoid using scouring pads or abrasive brushes, which can scratch the glass surface of your solar panels. Instead, use a gentle cleaning tool such as a sponge or a soft-bristle brush with a long handle.

Solar Panel Cleaning Solution

Persistent stains or bird droppings may require a solar panel cleaning solution. You can make your own by mixing water and a little mild dish soap. Apply the solution slowly, rub it with a soft brush, and wash it completely with clean water.

Maintain a Consistent Cleaning Schedule

Create a cleaning routine that suits your local climate and environmental factors. Areas with a lot of dust or pollution may need to be cleaned more frequently. Cleaning your TDG solar panels every 6 to 12 months is a good place to start.

Invest in Smart Cleaning Technologies

Consider investing in a robotic solar panel cleaner or other automated cleaning solutions. These tools can clean your panels efficiently and safely, reducing the need for hand cleaning.
