Fact checking more solar myths

As information about renewable energy continues to spread, it’s always a good idea to stop and consider the source of the information and if it’s factual or not. We’re here to help. We’ve already busted some solar myths about topics like how solar panels work, barriers to participation and radiation and noise pollution. The list of myths and false information is seemingly endless, so we’re back to debunk three more myths about solar energy.  

Myth: Solar energy isn’t reliable. While solar energy production does depend on the sun, modern technology has advanced to make solar a more reliable energy source when coupled with battery storage. Batteries store the energy generated from solar panels for later use. Even without batteries, though, solar energy production is incredibly reliable. 

The reality is that no type of generation, from coal to solar to wind, runs 24 hours a day, 7 days a week, 365 days a year. That’s why when we talk about reliability, we focus on achieving an energy mix from many different sources. This helps make the grid more resilient against power interruptions like severe weather.  

Myth: Solar panels need a lot of maintenance. Solar panels are designed to be low maintenance and have few moving parts. When dirt, mud or other elements block the panels from the sun and need to be cleaned, rain or snow naturally does the trick.  

Conducting maintenance on solar panels is also cheaper than the upkeep required at coal-fired facilities. New data shows that the fuel, operation and maintenance costs of solar is a third cheaper than coal. As machines and parts at coal-fired facilities get older, they become more expensive to maintain. Imagine trying to get a replacement part for a VCR player today. The parts are likely expensive and difficult to source. 

Myth: Solar project construction is harmful to the environment. When Alliant Energy engineers design renewable energy sites, they work with environmental experts and consultants to weigh many different environmental considerations, like species migratory routes and native seed mixes. We also work with local communities to protect roads. These steps help ensure our renewable projects improve our shared environment.  

Native seed mixes are planted to protect local species habitats, help improve water quality and expand pollinator habitats for bees, butterflies, beetles, bats and other flower-friendly creatures. These plants also help enrich the soil during the lifetime of the solar project and make the land healthier and ready for reuse at the end of the project. 

We work hard every day to make sure our projects benefit the environment from groundbreaking to decommissioning — and our efforts haven’t gone unnoticed. The Institute for Sustainable Infrastructure awarded our Wood County Solar Project in Saratoga, Wisconsin with the Envision Platinum Award highlighting its contribution to sustainable development and clean and renewable energy.
