4 FAQs about Photovoltaic power station inverter availability

What is a photovoltaic inverter (PVI) station?

It is based on the same best-in-class power conversion platform as our AMPS solutions, enabling greater scalability and flexibility. Hitachi Energy's Photovoltaic Inverter (PVI) station provides you with advanced control and power capabilities that are designed to meet complex technical requirements and the most challenging grid codes.

How many inverter availability factors are used in 1MWp solar power plant?

In our study, four 250 kW inverter were utilized in the 1MWp solar power plant, hence the average sum of the four inverter availability factors was considered for each financial year, and the value of PAF is computed and shown in Fig. 4. PAF is observed to be in the range of 92.44 % to 95.69 %.

Why is plant availability important in a solar PV power plant?

In a solar PV power plant, the plant availability factor is one of the important factors to be evaluated. This depends on the operative functioning of various components and grid regulation.

How to evaluate the availability factors of a solar PV plant?

In this paper, a simple method is proposed to evaluate the availability factors of a solar PV plant by considering the real time data of 1 MWp solar power plant that was commissioned in 2011 in south India. Generation start time, end time, and actual running periods of the inverter were selected as prominent data in the study.
