EPC Contractors & Project Developers

Solar Thermal Solutions for EPC Contractors & Project Developers

Millionsun has supplied flat plate collectors and solar water heating systems for projects across Europe, the Middle East, Southeast Asia, and Africa. Our role is to be a reliable equipment partner — certified products delivered on schedule, backed by technical documentation that supports bid submissions and commissioning alike.

Customer Overview

EPC contractors and project developers design, procure, and commission solar thermal systems for commercial, residential, and industrial projects. Equipment represents 30–40% of total project cost but carries 100% of the performance risk — the wrong product or a delayed delivery can ripple through the entire project timeline.

What EPC Contractors Look For in a Solar Thermal Supplier

Based on our two decades of working with partners across Europe, the Americas, the Middle East, and Asia, we know the criteria that matter most:
  • Certified performance data
  • System compatibility
  • Reliable lead times
  • Warranty that transfers
  • Technical support during installation
  • Previous project references

Common Challenges EPC Contractors Face

  • Project tenders require certified performance data, test reports, and schematics — compiling these from multiple suppliers risks bid disqualification.
  • Collectors, tanks, and controllers from different manufacturers may not integrate seamlessly, causing on-site rework and delays.
  • A delayed shipment can trigger penalty clauses and damage the contractor's relationship with the client.
  • EPC contractors need warranty terms that align with project handover timelines and can be transferred to the end client.
  • Without responsive technical support, on-site teams waste time troubleshooting issues that should have been anticipated.

How Millionsun Delivers Value to EPC Contractors?

Matched System Components

Collectors, tanks, and controllers are designed and tested as a complete system. No compatibility surprises on site. System sizing support is available from our engineering team during the design phase.

Production Scheduling Aligned to Project Timelines

We work with your project schedule, not the other way around. Production slots are reserved based on confirmed order dates, and regular status updates are provided throughout the manufacturing cycle. Standard lead time is 25–35 working days for OEM configurations.

Warranty That Supports Project Handover

10-year warranty on flat plate collectors with terms that can be transferred to the end client. Coverage documentation is prepared in the format required by your project contract.

On-Site Technical Support

Our engineering team is available during installation and commissioning — remote troubleshooting via video call, or technical documentation to support your on-site team. Spare parts can be dispatched within 5–7 working days if needed.

Certified Products — Ready for Bid Submission

Technical datasheets, performance curves, and certification certificates are available on request — no delays in preparing your bid package.
Every Millionsun flat plate collector carries third-party certification that can be included directly in tender documentation:

How We Helped an EPC Contractor
Deliver a 500-Unit Hotel Project on Schedule

Start Your Partnership
A Southeast Asia EPC contractor won a hotel solar water heating project covering 500 flat plate collectors across three sites. The job required certified, fully matched systems and delivery within 6 weeks to match construction timelines. After delays and penalties from a previous supplier, they needed a manufacturer they could fully trust for on-time delivery.

Our Solution

Millionsun provided:

  • 500 units of flat plate collectors (2.0 m², black coating) with Solar Keymark certification documentation for each batch
  • Matched water tanks designed to pair with the collectors as a complete system
  • Production scheduled to ship in two partial lots — 300 units at week 3, 200 units at week 5 — matching the construction phase at each hotel
  • Full technical documentation packaged per property for the contractor's handover to the hotel client
  • Dedicated logistics coordination for container booking and shipping documentation
