Ready to dip my toe in. I want to start with a small expandable hand tool/iPhone/ iPad/laptop charging station. My limitation is the number of panels. I would like to start out with just one. Time to charge does not have to be quick. I have full sun on the panel during the day. i have 1 reology panel already- any good to start with? At any onetime. Maybe 5 batteries, 3 iPhone, 2 iPads. Safety and reliability critical, cost not so much. Later on I would like to expand the number of panels. I have watched a ton of Wills videos. But I did not see anything n a super small scale. Thoughts? Thank you.
