even though these panels are smaller and more efficient, it may have been a tough sell to get two more of these installed on our roof
We've been considering a bracket system to get these mounted at an angle and adding more
We also have the Victron Energy SmartSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller (Bluetooth)
I love Will Prowse's videos, and his word is the gospel for us when it comes to RV electrical!!
In terms of recommendations, 1 battery may be enough, 2 will obviously be better! And if you can swing it, get the 400W of panels, it will definitely help with recharging on cloudy days.
Avoid shade, of course, but worst case, find a plug or drive to a dump station to get that bit of juice in the battery until the next sunny day.
I am so trying to assure myself that a no holes install would be safe, and what combination of materials work best. I need to evaluate if 200 watt panels, weighing
26.5lbs and 10 lbs more than your 100 watt panels, are good candidates for “no hole install”.
Flexible panels are tempting, but I think the technology has a way to go.
As you can see from my picture, the Bigfoot
21’s rooftop is very limited. My bathroom & cabin fans have rooftop covers. Plus I have a tallish AC cover. I would be hard pressed to put four, “shadow free” 100 watt panels on that roof.
I’ve installed the Victron 712 and appreciate the Bluetooth connection.
The Victron controller I’d my preferred choice. But I can live with another controller if I purchase a kit.
I need to move the trailer every few days to fill up my fresh water tank & dump my gray & black water tanks. That does help.
