Evaluation of solar power plants

The main services of solar power plant evaluation are:

Formal operational acceptance of solar power plants

Theoretical and practical efficiency inspection and analysis of solar power plants

Long term/periodic performance confirmation and maintenance of solar power plants

Third party confirmation and certification of profitability of solar power plants

Design scheme level and production evaluation of solar power plants

Verification and identification of abnormal production reduction in solar power plants

Selection, recommendation, and verification of key components for solar power plants (such as photovoltaic modules, inverters, etc.)

Random sampling and testing of photovoltaic modules in solar power plants

Third party asset evaluation of solar power plants

Customized testing and evaluation services in response to special customer requirements

 

Photovoltaic power station inspection and acceptance

The third-party testing agency accepts the commission of the photovoltaic power plant owner to conduct on-site testing and evaluation of the photovoltaic power plant prepared by the construction party to be delivered to the owner according to current international standards and national regulations, verifying whether the power plant meets the requirements of the design and owner, and providing professional technical services as a basis for the owner to implement completion acceptance.

 

Due diligence on photovoltaic power plants

The third-party testing agency accepts the commission of the photovoltaic power plant investor to conduct on-site testing and evaluation of the completed photovoltaic power plant according to current international standards and national regulations, verify whether the power plant meets relevant performance indicators, and provide professional technical services as a basis for the investor to acquire the power plant. At present, there are several tens of GW of photovoltaic power plants that have been put into operation in China, and more than ten GW of new projects are built each year. The corresponding demand for photovoltaic power plant testing and acceptance, as well as due diligence for photovoltaic power plants, is also increasing.

 

Solar thermal system testing

NormalTCI provides one-stop certification services for solar thermal products, tested according to various standards such as SRCC OG 100, OG 300, and EN 12975-1.

 

Main testing items for solar thermal energy:

Internal pressure resistance test and high temperature resistance test

Hail impact test - cyclic pressure/tensile load test

Testing the internal circulation temperature changes at the connection of the collector _ Performance testing of the hot water storage tank

Conduct frost resistance testing in an artificial climate chamber _ Material testing in a UV chamber

Conduct electrical safety testing on components - outdoor exposure testing

External thermal shock test Internal thermal shock test

Rainwater infiltration test steady-state thermal performance test

Impact resistance test
