Regional calculator for solar power creation?

[NickinCO]

There used to be a website (Renogy?) that had a calculator for power creation based on region, time of year, panel size, and orientation. Anyone remember or have a link?

I've been following your trailer power usage thread as I too have been calculating mine and recently purchased a 200ah lifepo4. I'm going to ask you some questions over there about your dewalt battery box.


Here is the solar calculator I've been using https://pvwatts.nrel.gov/pvwatts.php


You can enter the zip code you want info for and it will give you a monthly breakdown of your solar output. Be sure to adjust the system losses by selecting the calculator sign as it accounts for some downtime automatically and a few other variables.

Thanks! Starting to rethink my solar needs. 412ah at 80% SOC with the fridge on was fully charged by 11am this morning with the factory 300w panel. I turned the solar on at 9am. With good sun until 5-6pm I think it would take my battery to fully charged by the end of the day with the fridge running.
