Hourly accuracy is the fundamental point of difference that underpins PVsell’s accuracy. Consider that the proportion of solar generation that is export is the single-biggest factor in the ROI from solar. Whereas most solar calculators allow salespeople to ‘guesstimate’ export (in the process exposing your business to litigation), PVsell calculates export by analysing energy flows for every hour of the year (all 8760 of them). This hourly accuracy extends to accounting for shading, temperature, and panel aspect, and consumption, and incorporates system performance modelling from the US Government. That’s why you can trust PVsell’s results.
