Zhongtan builds distributed solar plants, industrial energy-saving retrofits and energy management systems, delivering projects from feasibility study to operation and maintenance.
Trusted by leading companies
Every step from briefing to after-sales has a defined owner and standard.
Two weeks of metered data and a site survey come before any equipment is specified.
The proposal states investment, saving and payback period, and is checked after commissioning.
We build and then operate the plant, so performance is our problem, not a handover document.
Grid connection, subsidy filings and environmental reporting are managed as one package.
Every item is validated in real use and can be adapted to your specification.

Three years in, what stands out is how little we have to chase them. They do what they promise, and they answer quickly when something comes up.
They are not the cheapest on the line, but the total cost works out lower. Far less rework and far fewer meetings, which matters over years.
Technical conversations are smooth — they understand the application, not just the product. Our requirements are understood accurately, which is rare.
