Solar panels up to 500W

Who is it for

Our offer of 400W solar panels is aimed primarily at professional installers, engineering companies, and RES system integrators. These types of photovoltaic modules are perfect for roofs with limited space, where maximizing available area without overloading the structure is crucial. Due to their standardized dimensions, modules up to 500W are extremely convenient to transport and install, significantly accelerating the execution of residential micro-installations and smaller commercial projects. The Solmix wholesale store supplies components from leading brands such as Jinko Solar, Trina Solar, and JA Solar, providing installation companies with operational reliability and failure-free performance.

What to consider

When choosing 400W solar panels, it is necessary to analyze their module efficiency, which directly translates to energy yield in variable weather conditions. Another important parameter is the temperature coefficient, which determines the power drop when cells heat up significantly in the summer months. It is worth paying attention to the technology used, such as Half-Cut or N-type cells, which handle partial shading better and offer a longer lifespan. For installers, the length of the product warranty and the linear power output warranty also remain crucial, serving as an important sales argument when dealing with the investor. A properly selected frame and mechanical resistance to snow and wind are further factors determining the robustness of the investment.
