Insolation Maps

---

The numbers listed on these maps are the average worst case insolation hours. Insolation hours provide a way of predicting the output of a solar module at a specific location. This data has typically been gathered over a number of years from weather stations located throughout the world. For example, if you have an SX-60 solar module that produces 3.5A peak power in a location that has 3 hours of insolation, it can be said that the SX-60 will produce 10.5AH a day.

A word of caution. This insolation information should be used only for estimates. Solar systems should not have a final design based on this information. This map does take into account small climate changes and may not be 100% accurate for all locations. We have a vast resource of databases that have specific cities listed with accurate insolation data.
