20 Watt - 12 Volt Solar Power system with 400 Watt Inverter for $ 115

I am going to build a very small  20 Watt Solar Power - 12 Volt generator to power some small DC and  AC appliances. Here in Ontario Canada, if I rotate the Panel I should get a good 8 hours of sunshine. So 20 watts * 8 hours = 160 Whr of power to trickle charge a 12 Volt Battery.

I'm on a very small budget of about $100 and I'll be looking for the best deals at Amazon and Walmart. This is the best deal Solar Panel I have found so far: ECO-WORTHY 20W 12V Solar Panel Kit: 20 Watt Polycrystalline Solar Panel & Battery Clips & 3A Charge Controller:
