3.5.1. Cost of Modules

The cost of a Hanwha Q cells Q peak G4.1 300 Rev4 monocrystalline module (with an efficiency of 18% and lifespan of 30 years), is € 0.34 Wp−<sup>1</sup> in Ireland [49].

Total module cost for each unit = (1800 Wp)·(€ 0.34 Wp−1) = € 612

Total module cost for all units = (1800 Wp)·(68)·(€0.34 Wp−1) = €41,616 (excl Value Added Tax (VAT) @13.5%) [50].
