6 FAQs about [Malaysia s photovoltaic inverter ratio]

What is the optimal inverter sizing ratio for photovoltaic power plants?

However, the optimal inverter sizing ratio (ISR) is a site- and system-dependent value. It can vary from 1.0 to 2.2, globally. So far, there is no study on the optimal ISR for photovoltaic (PV) power plants in Malaysia.

What is the optimal ISR for photovoltaic power plants in Malaysia?

It can vary from 1.0 to 2.2, globally. So far, there is no study on the optimal ISR for photovoltaic (PV) power plants in Malaysia. The industrial practice assumes that the ISR is either the inverse of the performance ratio of the system or value of experience design from other countries, which do not share the same climate.

What is the performance ratio of a solar PV system in Malaysia?

This technique is allowed if the solar irradiance of a site is mostly less than 1000 W/m2 [1-2]. Besides, the operation of a PV system is subjected to various performance losses, especially loss due to the temperature effect . Therefore, the performance ratio (PR) is usually less than 0.85 in Malaysia.

What is inverter sizing ratio (ISR)?

Since the inverter rated power can be smaller, a specific term called “inverter sizing ratio” (ISR) is used to indicate the ratio of the DC power capacity of the PV array to the AC power capacity of the rated output power of an inverter.

What is a Matlab model for a PV array and inverter?

Hourly solar radiation and ambient temperature records are used to develop a Matlab model for a PV array and inverter. The model aims to estimate the inverter’s efficiency in terms of PV array output power and inverter rated power.

What is the optimal solar irradiance in Malaysia?

It is observed that all sites in Malaysia show similar distribution profile and have a relatively high component of solar irradiance between 600 W/m2 to 800 W/m2. The distribution is quite different from that of Finnish , and therefore, the expected optimal ISR should be smaller. Fig 2 shows the variation of LCOE when ISR changes.
