Proper maintenance is necessary for the safe and reliable functioning of long-term solar power generation systems for decarbonization. So conducting electrical testing on the system according to the international standard is important. This article discusses the DC side testing of the IEC 62446-1 standard.
This standard also describes DC testing of the PV system, which can also be used for periodic testing of the system. In the standard, the test is classified into categories 1 and 2 according to the size of the PV system. Category 1 applies to all solar PV generation systems.
Several methods have been developed to predict the solar PV array output power. An estimation method used in Ref. proposes that the power output of a PV system is proportional to the insolation levels measured for the surface of a solar cell at any angular position.
Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been underway since very beginning for the development of an affordable, in-exhaustive and clean solar energy technology for longer term benefits.
As majority of our energy requirements are in the form of electricity, PV works on the principle of photovoltaic effect. The generation of thermal energy from solar can be realized using various solar reflecting collectors. Most of the technology works on the principle of reflection, radiation and convention or based on the thermosiphon effect.
For checking the voltage of PV modules connected in series. Check the operation and installation of control devices such as relay switches and circuit breakers. Test the insulation resistance to ensure electrical safety. All Category 1 tests must be completed and passed before moving on to the additional Category 2 tests.

Understanding solar power generation | GlobalSpec
In a typical solar power generation system, the sunlight strikes the solar panels, generating DC electricity in the photovoltaic (PV) cells. The DC voltage travels through cables to the inverter and the inverter converts the DC electricity into AC electricity. The AC voltage can then be used to power home or business appliances. The following are the details of the basic …
