500 kWp Industrial Rooftop Solar Plant - Precision Auto Corp
Sanand Industrial Estate, Ahmedabad, Gujarat | Capacity: 500 kWp DC / 450 kW AC
The Engineering Challenge
The client was consuming approximately 90,000 units of electricity per month at an industrial HT tariff of ₹8.40/unit. The factory roof was a curved standing-seam metal shed where no screw penetrations could be permitted to prevent water seepage during heavy monsoons. Additionally, high wind velocities in the open industrial park required certified 160 km/h wind load resistance.
The Lumussola247 Solution
Lumussola247 engineered a specialized non-penetrating aluminium standing-seam clamping system tested for 170 km/h wind shear. We deployed 910 units of 550Wp Bifacial Mono PERC modules paired with 5 units of 100kW high-efficiency 3-phase string inverters. The electrical team routed DC cabling through heavy-duty galvanized cable trays with integrated surge protection and chemical earthing.
