I am currently being forced to vacate my apartment in Northwest Orlando, where I have lived for 19 years, because of ridiculous rent increases. I am learning that my post-stroke social security income is insufficient to move into another apartment in the entire Orlando metropolitan area. So, I'm taking that as a clear signal that it's time for me to become an off-grid van dweller. Can all y'all suggest a maximum power, most efficient and affordable solar (preferably plug & play) system with portable panels, that might be upgradable as time progresses? Also, which insulation is best in both extreme heat AND extreme cold, as I would be traveling from Central Florida to Reno, Seattle and northern NH to spend time with family.??
