The average global PV module price in 2010 was 1.9 US dollars / watt, has dropped to 0.40 US dollars / watt in 2017, a 79% decline in seven years.So, in the next few years the PV module price still much room for decline? Bloomberg New Energy Finance (BNEF) forecasts that the downward trend of PV modules will slow down. By 2023, the average price of PV modules will be about US $ 0.30 / kWh (constant US $ in 2017) and 25% in 6 years.
It is worth noting that the PV modules are only part of the PV system, taking the case of large terrestrial PV power plants for example, the PV modules accounted for 38.8% of the system cost in 2010, up from 31.8% in 2017; BNEF expects the PV modules to account for 2023% 31.2% of the total cost of large-scale on-site large-scale PV power plants, with no significant change from 2017. For rooftop PV, the PV modules accounted for 29.3% of the system cost in 2010, down from 13.6% in 2017; BNEF expects 2023 The annual PV module will account for 23.2% of the total cost of rooftop PV.
