The average price of a commercial solar installation fell to an all-time low of $1.26 per watt ($/W) between August and September, according to data from Solar Choice’s installer network database. The drop was consistent across all solar system sizes, although there were slight fluctuations from city to city.

A note about the ‘Solar Choice discount’
From May 2014 until October 2015, calculations for our monthly Commercial Solar Price Index articles excluded the discount available through Solar Choice network installers exclusively to Solar Choice customers. From November 2015, however, we have excluded this figure, which works out to approximately 14c/W in most instances. The chart below retroactively applies this amount to every month since the Commercial Price Index’s inception to give a rough idea of how prices have fluctuated historically, but should be seen as an approximation as opposed to a completely accurate representation. (We’ll look into properly applying the actual, listed discounts to the dataset at some point in the near future.)
