How do you calculate Solar PV payback?

Are you still using Excel to calculate your solar payback for customers? Excel is a fantastically awesome tool for doing quick calculations, but when it comes to solar calculations there are heaps of reasons NOT to use Excel.

People don’t understand my spreadsheet!

Excel can do all the wrong things for some people – including making them want to fall asleep. If you’ve come up with a brilliant spreadsheet which perfectly expresses the temperature co-efficient of solar cells as a function of internal rate of return then the chances are, you’ll baffle and confuse most of your customers. What makes it even worse? The only customers who do understand your spreadsheet probably aren’t going to trust your calculations.
