The report, created by technical advising TÜV Nord in behalf of 'Solar Module Super League' member JinkoSolar, assesses the possible benefits on levelised cost of electricity (LCOE) and inner rate of return (IRR) of n-type modules over p-type, concluding the former to have "wonderful benefits" over the last.

The research study compared two separate utility-scale PV projects, designed in China and also Spain. The projects utilized Jinko n-type modules as well as compared their performance versus other mainstream high-efficiency modules readily available on the marketplace today.

The project in China was given a DC capacity of 120MW, provided a single-axis tracker system style with modules positioned in 1P, with a mean ambient temperature level of 3.8 degrees Celsius. At the same time the project in Spain was likewise given a DC capacity of 120MW, however it was created in a single-axis tracker system with modules put in 2P and also a mean ambient temperature of 19.5 degrees Celsius.

Complete certain details concerning the project place and style scheme, including potential balance of system (BOS) elements, in addition to capex projections, can be found within the report.

In both project locations, TÜV Nord's research found JinkoSolar's n-type modules to provide both a reduced LCOE-- of around RMB0.2955/ kWh in China and US$ 0.0480/ kWh in Spain-- and higher rates of return compared to p-type modules.

TÜV Nord said the research concluded that n-type items held benefits over p-type in both LCOE and project success, with its outdoor efficiency project locating the kW power generation capacity of the n-type module to be 5.26% greater than p-type generally.

With most sector estimates recommending that n-type will be the solar industry's dominant modern technology by 2025, investments in n-type manufacturing capacity are accelerating, with JinkoSolar having lately switched on an 8GW n-type module setting up facility in China and also expects to have 16GW of n-type cell capacity by the end of this quarter.
