Regular maintenance, professional inspections, and addressing potential defects will maximize solar panel efficiency. For more informative solar content, keep reading our blogs.

What causes hot spots on solar panels?

Hot spots, one of the most common issues with solar systems, occur when areas on a solar panel become overloaded and reach high temperatures relative to the rest of the panel. When current flows through solar cells, any resistance within the cells converts this current into heat losses.

Why do solar panels have a Snail Trail?

Occasionally, solar panels can develop small brown lines on the surface, termed "snail trails," because they give the appearance that snails have passed over the panel. Snail trails typically appear after only a few years and can have multiple causes, often attributed to lower-quality panels.

Why are Eva solar panels so bad?

While this may sound strange given solar panels are designed to be exposed to sunlight, problems often happen when the EVA is made from cheaper materials. EVA helps to maintain UV resistance in solar panels, with ultraviolet rays not being used by the panels, so when lower quality materials are used for this the resistance isn’t as good.
