Your questions answered
« How much ballast should I plan for? »
The ballast table supplied with the ValkBox3 indicates the required weight according to the wind zone and building height. In mainland France, generally allow 2 to 4 pavement slabs (30×30 cm, approximately 10–15 kg each) per unit. If in doubt, allow a slight excess of ballast — this poses no risk to the structure.
« How many ValkBox3 units do I need for my installation? »
One ValkBox3 is required per solar panel. For a 4-panel kit, order 4 units. For a system with 10 modules, you need 10. Each box supports one panel independently.
« Is this mounting system compatible with my panel? »
The ValkBox3 is compatible with all panels less than or equal to 1 150 mm wide. Check the « width » dimension in your panel's datasheet. Standard 440–470 W formats (approximately 1 134 mm) are compatible. If in doubt, contact our team on 04 83 58 04 79.
