How does the GRAM-BOX work?
It’s a solar mounting system built around a water ballast tank. Lightweight and easy to carry into position, then simply fill with water (up to 50L) to anchor it securely in place.
Designed to fit virtually any PV panel up to 205cm, the GRAM-BOX works on ground mounts, flat roofs and shallow pitches up to 10°. Fast to install, highly versatile, and ideal for everything from small DIY installs to large-scale solar farms.
