02Lower LCOE &Higher Efficiency

Global LCOE Trending Down

The global PV project bidding price dropped

considerably between 2013 and 2017 and has continued its downward trend.

This learning curve has been made possible by a

combination of technology innovation, economies

of scale and manufacturing experience.

Global LCOE Downward Trend

Ongoing reductions in equipment costs, improving

efficiency, declining financing and development costs

are expected to further lower the global benchmark LCOE.

Module efficiency continues to improve year-on-year,

driven by manufacturing innovation and a shift

towards new PERC (passive emitter rear contact),

half-cut cell designs, and larger wafers etc.

Seraphim S4 series solar modules continue to respond well at low irradiation with outstanding performance in a low temperature

environment, resulting in higher power generation. This, due to constant improvements in solar cell surface texturing, such as

sueded structures which increases the absorption and reuse of available sunlight.
