Determining which manufacturer is producing the best solar panels (based on cost and performance) in the USA isn’t a simple or straightforward task. Any such judgments made up until Feb. 1 – when the U.S. began levying new, punitive duties on imports of crystalline silicon photovoltaic (PV) cells and modules – will need to be revisited and reevaluated.
Why do we feel the need to revisit our rankings of the top 5 solar manufacturers now?
In late January 2018, President Donald Trump followed through on campaign promises to defend American manufacturers and manufacturing jobs, signing an executive order that imposes a punitive tariff(30 percent in year 1, dropping 5 percent each year to 15 percent in year 4) on all imports of crystalline silicon solar photovoltaic (PV) cells and panels regardless of where they originated. Having gone into effect February, the first 2.5 gigawatts worth of overall, global imports are exempt.
