Higher module efficiencies and inverters driving solar power cost declines
pv-magazine | December 20, 2018
NREL’s Q1 2018 cost report for solar power systems saw a 5% drop in residential costs and a 2.6% fall in commercial, but a 1-2% increase in the utility-scale space compared to the previous year. The purpose of the U.S. Solar Photovoltaic System Cost Benchmark: Q1 2018 is to provide bottom-up accounting for all system and project-development costs incurred breaking down hardware, labor and engineering costs.
