When it comes to installing solar panels on your roof, some homeowners may be hesitant to adopt it because of what they’ve heard or read on the internet. We live in an era of misinformation, which, unless we vigorously check our sources, can prevent us from living our best lives.
Myth #1:
Solar only works when the sun is shining. I still need power when it’s raining. Actually, solar technology can be leveraged in virtually any condition, including rainy and snowy days, because some sunlight still reaches the earth. Solar panels tend to perform best in cold and sunny climates because heat interferes with the conversion of sunlight into electricity. (Keep in mind that solar panels collect light, not heat.) On top of that, battery storage can be connected to your solar panels and provide energy at night. This is your clean-energy backup, as opposed to conventional backup generators—if the power goes out in your neighborhood, your power will stay on.
But the bottom line is, unless you’re among the tiny fraction of Indians who live more than about a mile from a power line, a home with rooftop solar panels is still connected to the electric grid. This means that if your solar energy system doesn’t supply enough electricity, the grid will supply the rest.
Myth #2:
Solar panels aren’t efficient enough. Some customers hear that solar panels have an efficiency rate of 22% and wonder why it’s not 100%. Some sunlight will be reflected off the panel or be turned into heat instead of electricity. Solar cell materials also can’t absorb all the types of light that make up sunlight, like infrared light. The world-record efficiency for a solar cell at room temperature under normal sunlight is 39%, but these cells are too expensive to be cost-effective for home solar panels.
Truth is, the sun produces an enormous amount of energy—the sunlight that shines on the earth in just one and a half hours has more power than the world consumes in an entire year. With this huge energy supply, commercially available solar panels provide plenty of power to meet your home’s needs, at a cost at or below electricity provided by the grid in most parts of the country
