The questions I have the opportunity to answer the most is' "Once my Renewable Energy (RE) System is installed what can I expect for production or How soon will this system pay for itself." The answer varies depending on location of the RE system, State and Federal incentives and the type and manufacture of the RE equipment.
Following you find links to web sites where you can find calculators which will estimate the production of RE systems by type/manufacture
Below you will find projects that the RootCellar designed and installed. Click on the link to view production in real time.
