One reason is that when solar modules are rooftop mounted, they use the building structure and electrical system to minimize additional materials that would normally be required for ground mount and carport solar facilities. Net metered rooftop projects therefore bring a desirable financial benefit that outweighs most challenges.

Electricity costs constitute a significant share in overall operating costs for a commercial establishment. It’s a given that most modern offices have large number of computers & other electronic devices, centralized HVAC systems, etc., that has to run continuously for general day to day operations resulting in high electricity costs. This cost increases exponentially with increase in size of building and manpower. Rooftop solar plants in recent times have emerged as the ideal solution to reduce expenditure in electricity bills by as much as 70%.
