As an innovation team, PandaSolar always develops new products to meet different market demands. The adjustable solar ballasted system is designed to meet customers' different installation requirements, so that customers can choose the best angle that can generate the largest energy. The reasons why we can achieve the purpose are that we designed a 5-degree highening part. The original angle is 10 degrees. If you wanna increase to 15 degrees, the higher parts come into play. To increase the angle to 20 degrees, just add one more heightening part. It is made of high-quality aluminum material and matched parts all made of stainless steel 304, which ensures highly anti-corrosion capability and longevity.
