7. Is the solar energy more useful than any other renewable energy? At this moment yes, the solar is less expensive, two years ago was the air energy the cheapest to produce, but right now the prices to produce solar energy is getting lower. 8. What kind of new devices will come up with the use of the solar energy? The batteries, this will be the complement of the solar panels, so you will have energy everywhere you want maybe in mountains or wherever you want also you would be able to storage your energy. 9. How does the solar panel work? When the light of the sun hits the solar panel surface the electron on the surface of the material gets excited and the last electron of the atoms goes into the channels of the panel and that the way to collect the energy. 10. Does the solar panel have to be connected to any source of energy? No, the solar panels just need the sun, as soon as the sun is getting lower you will not receive the energy but it doesn’t have to be connected to anything to produce energy during the day. 11. solar panels are expensive, is it a good investment buy them? Yes is a good investment. Expensive to me is don’t have the solar panels, why? Because if you compare how much you are going to pay for 25 years to CFE to buy the energy is more expensive than pay just 5 years your solar panels and produce your own energy. In conclusion the solar panels are a very good investment and a very good way to protect the environment because it is a renewable energy.
