How Much Power Will a Solar Module Produce in my
Insolation Map Index
The numbers listed on these maps are the average worst case insolation
hours. Insolation hours provide a way of predicting the output of a
module at a specific location. This data has typically been gathered
a number of years from weather stations located throughout the world.
example, if you have an SX-60 solar module that produces 3.5A peak
in a location that has 3 hours of insolation, it can be said that the
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
This map does take into account small climate changes and may not be
accurate for all locations. EcoVantage has a vast resource of databases
that have specific cities listed with accurate insolation data. Please
allow us to verify any critical design before purchasing.
