Installers & Service Providers

Solar Thermal Products Built for Installers & Service Providers

Millionsun designs our products with the installer in mind. Standardized connections, clear labeling, documented installation procedures, and a responsive after-sales team — because the easier a product is to install and support, the better it is for your business.

Customer Overview

Installers and service providers are the last and most important link between solar thermal products and the end customer. You design the system, install it on site, commission it, and support it for years after. The product’s reputation — and your reputation — depends on how well it goes together, how reliably it performs, and how quickly issues are resolved when they arise.

What Installers Look For in a Solar Thermal Supplier

Standardized port sizes, labeled connections, and step-by-step installation procedures that reduce time on site
Installation manuals, wiring diagrams, and troubleshooting guides that are accurate and easy to follow
A straightforward claim process that does not require the installer to chase paperwork for weeks
Commonly needed parts (gaskets, sensors, controllers) available to ship within days, not weeks
The ability to order 1–2 units to test a product before committing to larger quantities
A phone number or contact who can answer installation questions during the working day

Common Challenges Installers Face

How Millionsun Delivers Value to Installers?

Designed for Fast Installation

Flat plate collectors come with standardized 22 mm copper connections, pre-assembled frames, and labeled inlet/outlet ports. Complete system packages arrive with all components matched — no on-site fitting surprises.

Documentation You Can Use On Site

Installation manuals include step-by-step procedures with diagrams, wiring schematics, and torque specifications. No assumptions about prior knowledge. Available in English and other languages on request.

Warranty Process That Works for You

Serial number on every collector. Report an issue online or by email, provide the serial number and a photo — we verify against production records and arrange resolution within 5 working days. Replacement units are included in your next shipment or dispatched separately.

Low MOQ for First Orders

Need one unit to evaluate? Order a sample. Need five for a project? We accept small orders. Your first order should match your actual requirement — not a factory minimum.

How We Helped an Installer
Reduce Average Installation Time by 30%

An installer in Australia had been using a different brand of flat plate collectors for residential solar water heating installations. Their standard installation took two technicians a full day — partly because the collector connections required on-site modifications, and partly because the included manual was unclear about pipe routing and electrical connections.

They decided to trial Millionsun collectors on a three-house project and compare.

Our Solution

Standardized 22 mm copper connections matched their existing plumbing stock — no need to carry extra adapters
Pre-assembled frame reduced framing time by approximately 40 minutes per installation
Clear step-by-step manual with connection diagrams meant the lead technician could brief the team in 10 minutes instead of working through unclear instructions on site
Technical support available by email for a question about the controller wiring — answered within the same working day
