Highlights :

N-type technology has gradually become the mainstream product technology in the photovoltaic market.
Its benefits are said to include not just an increase in the power output of the PV panels, but also the substantial increase in the module efficiency and the considerable reduction in the cost of the system.

N-type Solar Module Produces 5.26% more Power than P-type one: Report

Latest research has found that the power generation capacity of the N-type solar module is 5.26% higher than that of the P-type module with the same dimension, on account of the former’s lower levelized cost of electricity (LCOE) and higher internal rate of return (IRR).

According to a new report by technical service provider TÜV Nord, N-type technology has gradually become the mainstream product technology in the photovoltaic market, and its benefits include not just an increase in the power output of the PV panels, but also the substantial increase in the module efficiency and the considerable reduction in the cost of the system.

To make its case in the favour of N-type technology, the report studies two hypothetical 120MW utility scale ground-mounted PV power plants. Through technical plan review and financial benefit comparison, module-maker JinkoSolar’s N-type high-efficiency modules JKM610N-78HL4-BDV (denoted by 182-78N-610W), JKM565N72HL4-BDV (denoted by 182-72N-565W) and other mainstream high-efficiency modules on the market (denoted by 210-66-665W, 210-60-605W and 210-55-555W) are compared in terms of their respective LCOE and IRR.

LCOE is the full lifecycle costs of a power generating technology per unit of electricity. It is an economic assessment of the average net present cost of electricity generation for a generating plant over its lifetime. It accounts for all lifecycle costs of the system, including operation, maintenance, construction, taxes, insurance, and other financial obligations of the project.

As per the report’s findings, in China, the plant that used 182-72N-565W module has the lowest LCOE, which is ¥0.2955, and in Spain, the plant that used 182-78N-610W module has the lowest LCOE which is $0.0480.

IRR is generally considered to be the profitability of project investment, clearly reflecting the efficiency of investment use. In China, the plant that used 182-72N-565W module has the highest IRR, which is 13.79%, the report found. In Spain, the plant that used 182-78N-610W module has the highest IRR which is 15.80%.
