Factory rooftop solar

Cut daytime power costs when factories use the most, with typical payback in 4–6 years

Most factories draw the most power between 08:00 and 17:00, exactly when panels produce, so almost every unit is used on site.

What we do

Drone roof survey and a structural check by a civil engineer
System sized from 12 months of real load data, never oversized
All permits handled: ERC, utility and building permit (no factory licence needed since 28 Dec 2024)
Installed by our own crews, no subcontractors

Invest for the highest return, or sign a power purchase agreement (PPA) with no upfront cost and pay 15–25% less than the grid tariff.

Site survey and structural check3–7 days
Drone roof survey; a licensed civil engineer certifies the roof can carry the panels
System design and single-line diagram7–14 days
Yield simulated from 12 months of load data, sized to daytime demand
Building permit15–30 days
Filed with the local authority under Ministerial Regulation No. 72 (2025), which eased rooftop rules
Factory licenceNo longer needed
No longer required for rooftop solar of any size since 28 Dec 2024
ERC licence or exemption7–15 days
Self-use systems under 1 MW are exempt from a generation licence but must notify the ERC
Utility interconnection approval30–60 days
MEA about 30–45 days, PEA about 45–60 days from a complete file
Installation14–45 days
Our own crews, without stopping your production line
Inspection, meter and commissioning7–15 days
The utility checks anti-islanding protection, then the system goes live

About 2.8–6.2 months in total; some steps run in parallel and we handle all of them
