When discussing wattage, voltage, and all things electrical, it can sometimes sound very abstract when you try to place them into real-life terms.  Here are some common devices and items to give you a rough idea of energy use with a 200-watt solar panel: • A 60-watt lightbulb could run for 11 hours • A laptop could recharge for around 2 hours • A TV could run for 2 hours • An energy-zapping microwave could be on for just one hour Of course, you wouldn’t need to run all your appliances for those times, but it gives you an idea of how quickly 200 watts can disappear.
