The cost reduction includes the decrease in initial costs, O&M costs and financing costs. Regarding the increase in electricity generation, the most important factor is related to the efficiency and the lifetime of the PV modules and the inverters.
To reduce this financial gap and manage the decrease of PV costs, the Chinese government published the Notice on matters of PV power generation in 2018, which is referred to as the “531” policy, reducing the subsidies for PV from 0.36 CNY/kWh to 0.32 CNY/kWh.
The material and installation costs amounted to USD 13.35 per W at the time of installation (4.80 USD/W for modules and 8.55 USD/W for installation and BOS). The nominal power of the system is 19.8 kW. The plant is monitored in real time on a minute basis.
