This is a quick video of our 100w solar kit set up on our garden shed. It was a kit brought from Amazon and a leisure battery brought from eBay. After a year it is still going strong and is being used to charge battery packs, which can then be used in the house to charge phones, tablets, headphones, etc. It has worked well, especially in the summer but no so much in the winter. The next step is to add another panel and then an inverter to run 240v devices via a 3 pin plug.
