10 Biggest Myths about Solar




There are many myths and lies about the solar industry.

It can be difficult to decide what to believe, from the carbon footprint of making a solar panels to cost vs. benefit ratio of buying a solar system.


We felt it was time to confront some of the myths that are being disseminated online, and many of them being shared in our social networks.


These are the top ten biggest myths about solar panels.


Myth 1 - Solar panels use more energy to make than they can generate


Verdict : False. Solar panels produce more electricity over their lifetime than what they use when built.


This myth has been around for years. But the irony of it is that each year it circulates, the more absurd it becomes. Solar panels are now more efficient due to technological advances and improved manufacturing techniques.


ReNew magazine's 2009 solar panel lifecycle assessment showed that it takes between 1.7 to 2.3 years for a solar panel system to make its carbon costs back. This included factors such as the cost of production, transportation, and product usage.


Your solar panels should last for between 20-30 year before they need to be replaced. Often, your warranty covers 25 years. This means that your solar system should be able to pay for its manufacturing costs in just 11 years, if you use the 2.3 year pay-back rate


Myth 2: Solar panels don’t work on cloudy days


Verdict : False. Solar panels can generate solar energy wherever there is sun, but less efficiently.


Solar panels can still produce energy even in colder conditions or on overcast days. The clouds don't block all sunlight. If they did, it would be dark everywhere the sun shines. The type of clouds that cover the sky will also affect the degree to which sunlight is blocked.
