Ans: You may already know the working of a solar panel if you own any solar-based gadgets, or have used a solar panel before. And with that, you might also know that solar panels are quite slow in terms of power output, especially when compared to the standard wall outlet supply. But, they still offer you clean energy and you can charge your generator almost anywhere, given that there is ample amount of sunlight. On the other hand, fuel generators rely on external fuel to generate energy. Thus, you will always have to travel with a few extra gallons when you are planning to use the generator on long trips. While the fuel generator will definitely offer you an instant power supply, it also emits residue gases that are certainly harmful to the environment as well as for your health.
