Solar (photovoltaic) panel prices
IRENA presents solar photovoltaic module prices for a number of different technologies. Here we use the average yearly price
Sensitivity analysis indicates that the improvement of efficiency, yield and decrease in materials cost significantly reduce the cost of the modules. Analysis of the module cost and LCOE indicates that the PSCs have the potential to outperform the silicon solar cells in the condition of over 25% efficiency and 25-year lifetime in future.
In 2023, the cost of the crystalline silicon modules has decreased largely with the latest price falling to 0.1 $ W −1, corresponding to a decrease of over 75% compared to that in 2017 [39, 40, 41]. On the other hand, many startup companies have emerged to manufacture PSMs around the world.
Each module has an area (with frame) of 1.9 m 2 and a rated power of 400 watts, corresponding to an efficiency of 21.1%. The monofacial modules were assembled in the United States in a plant producing 1.5 GW dc per year, using n-type crystalline silicon solar cells produced in Southeast Asia.
Scenario 2 shows the possibility that PSMs can obtain a cost similar to that of the crystalline silicon modules, under the coordination of over 25% efficiency, 99.5% yield, 40% materials cost reduction, 50% equipment investment reduction and 30% electricity cost reduction.
