Project lens
Sunket Supply scope
Product supply, inverter matching, European warehouse coordination and project-scoped support.
Best fit
Commercial and industrial buyers, installers and distributors planning energy projects in Europe.
The challenge
Turn factory roofs into generation
Manufacturing sites have large roofs and high daytime demand — an ideal match for rooftop PV.
High daytime electricity consumption from production lines is expensive at commercial tariffs.
Large roof areas sit unused while energy costs rise.
Production cannot tolerate downtime during installation or commissioning.
How it works
How factory rooftop PV works
Generation sized to daytime production demand, with optional storage.
- 01
Rooftop array
Tongwei modules from 645 W to 765 W are laid out against usable roof area, structural constraints and the selected inverter inputs.
- 02
Inverter
Generation feeds production loads directly during operating hours.
- 03
Optional storage
Add a C&I battery to shift surplus and shave demand peaks.
- 04
Site & grid
PV, storage and grid exchange follow the approved electrical design and operating logic.

Architecture review
For PV-plus-storage projects, the power-conversion architecture is matched to the roof layout, load profile and grid requirements.
Optional battery
Hithium 261 kWh C&I storage can be evaluated for self-consumption and peak shaving.
FAQ
Frequently asked
Can the roof handle PV?
Most modern industrial roofs can. Structural and layout suitability is confirmed during project planning.
Do I need to stop production to install?
Access, isolation and changeover needs depend on the site electrical design and installation method. A qualified local installer should agree phasing and any required downtime with the operator before work starts.
Should I add storage now or later?
Either sequence may be possible. If storage may be added later, the designer should reserve the required electrical capacity, space, protections, controls and grid-approval path from the outset.
