Another increasingly important application is charging stations for electric vehicles (EVs), enabling logistics companies to run solar-powered delivery fleets and reduce reliance on fossil fuels. The extent to which a warehouse can operate on solar energy depends on the size and efficiency of the solar array.
Some facilities may be partially powered, using solar as a supplement to grid electricity, while others can become fully solar-powered, achieving net-zero energy consumption. In cases where the system generates surplus energy, net metering allows excess power to be fed back into the grid, offering cost savings or credits from utility providers. This seamless integration of solar technology not only reduces operational costs but also positions solar-powered warehouses as a cornerstone of sustainable logistics infrastructure.
