455w photovoltaic panel maintenance

What are the standard test conditions for photovoltaic modules?

Standard Test Conditions: 1000W/m2 Irradiance, 25°C Cell Temperature and 1.5 Air Mass. Under normal conditions, the photovoltaic modules may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions.

Are photovoltaic modules dangerous?

Photovoltaic modules can produce DC electricity when exposed to light and therefore can produce an electrical shock or burn. DC voltage of 30 Volts or higher is potentially lethal. Modules produce voltage even when are not connected to an electrical circuit or load. Please use insulated tools and rubber gloves when working with modules in sunlight.

Can a PV system be exposed to sunlight?

Wires, plastic wire-ties, or grommets/bushings are exposed to sunlight. Even products listed for direct UV exposure will show degradation over the long life of a PV system and require eventual replacement.
