What is a "power production meter" in the context of PV systems?

A "power production meter" in the context of photovoltaic (PV) systems specifically measures the amount of energy produced by the PV system. This type of meter is critical for monitoring the performance and efficiency of solar panels, as it allows system owners and operators to assess how much electricity is generated over a specific period.

Power production meters typically provide data in kilowatt-hours (kWh), enabling users to compare actual production to expected outcomes based on system specifications and solar irradiance. This information is vital for ensuring the system is functioning properly and for making informed decisions regarding maintenance or potential upgrades.

The other options do not accurately represent the function of a power production meter. Energy consumption meters measure how much energy is being used by a facility or device, while battery level meters specifically monitor the state of charge for battery systems. Voltage testing meters are used to check voltage levels but do not provide insights into energy production. Thus, the definition of a power production meter aligns clearly with option C.
