On-site acceptance of photovoltaic equipment
On-site acceptance refers to checking the quality before acceptance when the photovoltaic equipment reaches the location designated by the customer. On-site acceptance is to comprehensively assess the quality of the equipment and clarify the responsibilities of all parties. At the same time, it helps investors and owners to strengthen the quality control of power plants and reduce the failure rate in the later period.
Brackets, photovoltaic modules, combiner boxes and inverters are key equipment for photovoltaic power plants. The quality differences will directly affect the operation of the power plants. Huayang Testing provides on-site acceptance services for power plants owners, EPCs, construction companies, manufacturers, etc. based on IEC and GB photovoltaic standards and technical agreement on equipment procurement.
