Solar electricity works exactly the same as the electricity you buy from the utility company. You turn on lights, plug in lamps and power appliances the same way you do right now. In fact, if you didn’t see solar modules on the roof, you’d never notice any difference—except a lower electric bill. Relax, It's Easier Than You Think While the science of converting sunshine into electricity is complex,the idea is pretty simple. Solar electricity is generated by a group of solar modules called an array that's installed on your roof or in your yard. When sunlight falls on the solar modules, a DC electrical current is created instantly. The DC electricity is fed into an inverter that changes it to standard AC electricity—the same kind your home already uses. Solar Power Is Highly Reliable Solar electricity has been in use for more than 50 years and is proven to be highly dependable. Unlike other methods used to generate electricity, solar doesn’t rely on moving parts that can wear out. Sharp modules come with a 25-year limited warranty, and some systems installed more than 40 years ago are still performing. Little Maintenance Is Required Occasionally, a solar array should be rinsed off with a hose to clear the dust or debris that blocks sunlight and reduces efficiency. That’s about all that’s required.
