As you decide on the best direction for solar panels, it’s important to keep an eye on solar panels’ price to ensure your investment aligns with your budget and energy-saving goals.

Bifacial Solar Panels

Bifacial solar panels have the unique ability to capture sunlight from both sides, increasing their overall energy generation. They can absorb direct sunlight on the front side and also capture reflected light from the ground or surrounding surfaces on the back side. Bifacial panels are particularly effective in locations with a high albedos, such as snow-covered areas or buildings with reflective surfaces. They offer enhanced performance and are suitable for ground-mounted installations.

Solar Panel Maintenance

One of the attractive features of solar panels is their low maintenance requirements. However, to ensure their longevity and efficiency, some maintenance is necessary:

Regular Cleaning

Dirt, dust, and debris can accumulate on the surface of the panels, reducing their efficiency. Regular cleaning with water and a soft brush can help maintain their performance.


Periodically inspect your solar panels to ensure they are free from damage, such as cracks or loose connections. Contact a professional if you notice any issues.

Inverter Maintenance

The inverter is a crucial component of your solar panel system. It should be checked and maintained as recommended by the manufacturer.

Tree Trimming

If you have trees near your solar panels, trim branches that may cast shadows and obstruct sunlight.

Pest Control

Ensure that birds, rodents, or other pests do not nest or cause damage around your solar panels.

Snow Removal

In areas with heavy snowfall, you may need to remove snow from the panels to ensure they continue operating.
