Recently purchased the 200 watt starter system in series with the renogy 40 amp mppt tracer controller. Eventually will be adding more panels. This system will power a tv or laptop,modem and wifi router for about 4 hours a day total. I am planning a 215ah battery system in 24 volts. 2x6volt in a series. I am near Pensacola FL. Any idea how long it would take to charge this system with what I have now. I am planning to add another 100 watt panel (expansion kit) next month

Hi Azwrmn The link below will give you information to make a reasonable informed guess. I dont know the kind of panel you have, but with the information on the labels on the back of your panels and the pdf you can get some reasonable aproximation. There are many factors to account for in trying to estimate "how long" so it is almost impossible to say with a high degree of certainty. You also have to account for system losses and inefficiencies. The pdf will also give you suggestions for the proper tilt to get the most out of your solar resource. rredc.nrel.gov/solar/pubs/redbook/PDFs/FL.PDFIf your charge controller has a metering info feature that should help you determine how long will it take with your solar resources. Hope this helps. GAT |
