Testing of PV Power Plants
The laboratory provides PV power plant testing service in accordance to Chinese standards CNCA/CTS0004, CNCA/CTS 0016) and IEC 62446-1 standard, using advanced power station testing equipment to provide authoritative third-party testing data and analysis reports for PV power plants in various stages (construction, operation, trading, etc.).
Our business covers:
2 PV Power plant investment feasibility/profitability assessment consulting;
2 Overall value evaluation of PV power plant;
2 PV power plant acceptance testing;
2 PV power plant performance testing;
2 PV power generation system performance parameters (PR value) calculation;
2 Operational evaluation (generation efficiency, attenuation) for PV power plants.
We have a professional testing team, be ready to serve you at any time.
The following is our testing scope, welcome your inquiries. (Tel: +86 519-81581728 E-mail：[email protected])
