Escalating Self Consumption

Last night it occured to me that my IRR calculations would be improved if I allowed the self consumption value to change over time. Previously I had it so that the self consumption rate was fixed as a percentage of generation. This means that over time the annual amount of self consumption goes down as a result of total generation shrinking due to degredation. Well... That's no good. I figure you should be able to hold the self consumption variable constant or even make it go up over time. Today I added some lines of logic to accomplish this.

If you want to make is so that the annual amount of self consumption shrinks with the degredation of the modules select Self Consumption Escalator NO. The calculator will follow the normal protocol.

If you want to make it so that the annual amount of self consumption remains constant select Self Consumption Escalator YES and assign a Self Consumption Escalator Rate of 0%.

If you want to make it so that the annual amount of self consumption goes up select Self Consumption Escalator YES and a assign a positive value for the Self Consumption Escalator Rate. Keep the Escalator Low - anything above 1% will probably give unrealistic results.
