I've always been intrigued by solar energy but the only thing I had were just two solar powered lanterns which is just simple LED light. I got this little charger which is one of the most simple ways to get solar energy for other stuff in the home. Unlike other solar setups it's all one piece except there is no main battery. There are two USB ports which I connect two small power banks to. Once they're full I use them to recharge our phones. They don't recharge fast enough to have all of our phone use be 100% solar but it does help the planet and our power bill.
