One of the most frequently used systems for installing PV plants on gravel-covered surfaces is the Sun Ballast East-West system: revolutionary, sturdy and offering countless advantages.
The East-West system is one of the best choices you can make if you need a highly wind-resistant photovoltaic installation, which can be especially important on very tall buildings such as apartment buildings and condominiums, when you have limited roof space, and also in cases where the building does not have optimal sun exposure and therefore it is not possible to set up a south-facing installation. The dual East-West orientation is ideal not only for situations of sub-optimal exposure, but also for situations when you need continuous energy production for several hours during the day, not only when the sun is highest in the sky.
