Solar as an engineering project, not a product sale
A solar plant is only as good as the load study behind it and the maintenance regime after it. We cover the whole cycle — feasibility, sizing, design, equipment supply, installation, commissioning and long-term performance.
What this division covers
Solar Modules
- Monocrystalline modules
- N-type modules
- TOPCon technology
- HJT technology

- Commercial and industrial modules
- Utility-scale modules
Inverters
- Residential inverters
- Commercial and industrial inverters
- String inverters
- Central inverters
- Hybrid inverters
- On-grid / grid-tied inverters
- Off-grid inverters
Balance of System
- Mounting structures, rails and clamps
- Roof, ground-mount and carport structures
- DC and AC cables, MC4 connectors

Typical scopes we are asked for
How a solar energy enquiry moves
Same ten stages as every SWIZ ENERGY scope — the depth of each stage changes with the size of the job.
Requirement
You send a BOQ, drawing, part number, datasheet, photo or a plain description of the problem.
Technical review
An engineer reviews the requirement and comes back with clarifications, not a guess.
Survey & design
Where the scope needs it: site survey, load analysis, sizing, drawings and BOQ preparation.
Sourcing & RFQ
We issue RFQs to a matched supplier panel and pull in manufacturer documentation.
Comparison
You receive a technical compliance sheet alongside the commercial comparison — both, not one.
Order & inspection
Purchase order, manufacturing follow-up, expediting and inspection before shipment.
Logistics & delivery
Freight coordination, documentation and delivery to the site or consolidation point.
Install & commission
Installation supervision, testing, commissioning and handover with as-built documentation.
After-sales
Spares, maintenance contracts, O&M support and repeat-order pricing.
Repeat & framework
Call-off pricing, agreed stock holding and framework arrangements for recurring items.
Often combined with
Engineering Services
Electrical, mechanical, HVAC, automation, civil.
OpenGlobal Procurement
Sourcing, RFQ management, vendor evaluation.
OpenIndustrial Trading
