By the terms photovoltaic (PV), systems that use semiconductor material for converting light into electricity are referred to which results in Photovoltaic Effect. Solar Testing PV systems are available in several varying sizes and formats and for that, it is required that an understanding of PV components and how they are used is needed before Solar testing can be performed.
In a very basic PV System, there lies a PV module which could be one or many modules linked together for forming a PV array. Connected in series, these modules are called strings. The PV module converts the Sun's light energy into DC electrical energy using semiconductor materials. To compensate for the shading of the PV modules, some systems can be optimized, this effect can greatly reduce system performance. The DC output from a module into AC electricity is converted by the inverter. This output can be fed to a storage system, a load center, or both of them. AC Modules are a combination of both the PV module and inverter in one unit. Microinverters are used by these components which are small inverters that are attached to the back of the module, for producing AC electricity directly from the PV module. In more advanced Solar Testing Equipment, combiner boxes (to take multiple strings), ground (Earth) fault protection, fused connectors, charge controllers (voltage regulators), and switchgear is incorporated. Qualified PV technicians / PV engineers carry out PV testing. Solar Testing can be done at many stages for instance at the pre-installation stage (testing of individual modules), during the ongoing operation and maintenance stage (to ensure the PV system integrity and performance is maintained) or while commissioning (where the system is being installed). With us, you can get custom solar/photovoltaic test equipment that uses several types of PV test and measurement instrumentation from our industry-leading partners. We target to help users achieve ever-increasing solar cell efficiency and reduced cost demands, reliable, accurate, fast and repeatable test results. To achieve high performance, manufacturable solar cells, arrays, and modules require necessary research, design, and development work which is assisted by our solar testing equipment. Dutco Tennant LLC can guide you about which is the best instrument for your requirement. After the analysis and optimization of parameters, we can integrate an entire test system together for your application.
