Commercial Rooftop Solar Systems
We turn industrial roofs into energy for self-consumption, with structural and electrical engineering, permits and in-house installation teams.
Design starts with consumption and the roof
A system on an industrial building cannot be sized only from available square metres. FDGL analyses bills, load profiles, shifts, contracted power, roof condition and business objectives to maximise self-consumption, safety and maintainability.
Energy analysis
F1, F2 and F3 consumption, load curves, seasonality and planned production expansion.
Roof assessment
Roof type, load capacity, waterproofing, skylights, sheds, shading and safe access routes.
Complete engineering
Modules, inverters, switchboards, protection, cables, monitoring, grid connection and technical procedures.
Essential checks before installation
- Structural load-capacity report
- Wind, snow and permanent-load verification
- Fire-prevention and production compatibility
- Management of skylights, smoke vents and lifelines
- Assessment of asbestos or roofs requiring refurbishment
- Work planning without stopping production

Why companies choose FDGL
Anyone can sell a photovoltaic system; only a few can guarantee correct design, installation and long-term operation. FDGL has worked in photovoltaics since 2007, with its own engineering office, internal crews and several megawatts completed across Italy.
How much could your company save?
Send recent energy bills, the facility address and roof information. FDGL will prepare a technical and financial assessment based on your real load profile.
Frequently asked questions
How many kWp can be installed on an industrial roof?
It depends on usable area, obstacles, safety distances, structure, module type and grid capacity. A technical survey is required.
Is battery storage always necessary?
No. For companies with high daytime demand, direct self-consumption may be more cost-effective. Storage is assessed against the load curve.
Does FDGL manage the paperwork?
Yes. FDGL manages engineering, grid connection, technical and administrative procedures and commissioning documentation.
