Year 1 Generation
Please enter the amount of electricity that will be generated in the first year of the solar installation.
This information is usually provided to you by the solar developer or installer by using industry standard modeling tools. However, if an estimate has not been provided or if you would like to run your own scenarios, NREL’s PVWatts tool allows users to easily estimate the production of hypothetical systems based on their geographic location. When using PVWatts, if you don’t know the particular details necessary for the inputs, utilize the automatically generated inputs. The final screen will give you a general estimate of the annual kWhs produced by that system. Of note, this tool asks for the system size in kW DC.
