Solar energy has gained significant traction over the last decade, but despite its growing popularity and proven benefits, many myths and misconceptions still surround this clean energy source. These misunderstandings can discourage homeowners and businesses from making informed, sustainable decisions.
In this blog, we’ll tackle some of the most common solar energy myths and separate fact from fiction to help you see the full picture of what solar really offers.
Myth #1: Solar Panels Don’t Work in Cloudy or Cold Climates
Fact: Solar panels can still generate electricity on cloudy or cold days.
While solar panels are most efficient in direct sunlight, they continue to produce energy in overcast or diffuse light conditions. In fact, countries like Germany — known for its cloudy weather — are global leaders in solar adoption. Solar panels also operate more efficiently in cooler temperatures, as extreme heat can slightly reduce their performance.
Myth #2: Solar Energy Is Too Expensive
Fact: The cost of solar has dropped by over 70% in the past decade.
Thanks to technological advancements, mass production, and supportive policies, solar energy is more affordable than ever. Many states offer rebates, tax incentives, and net metering programs, and financing options like solar loans, leases, and PPAs make it accessible without high upfront costs.
In most cases, the long-term savings on electricity bills more than outweigh the initial investment.
Myth #3: Solar Panels Require Constant Maintenance
Fact: Solar panels are extremely low-maintenance.
Once installed, solar panels require minimal upkeep. They have no moving parts and are built to withstand rain, wind, snow, and hail. Occasional cleaning (2–3 times a year) and an annual inspection are typically enough to keep them running efficiently.
Most systems also come with long-term warranties (20–25 years) that cover performance and durability.
Myth #4: Solar Panels Will Damage My Roof
Fact: When installed correctly, solar panels can protect and even preserve your roof.
Professional solar installers assess the roof’s condition and structure before installation. In fact, panels can shield the roof from direct sunlight, rain, and debris — potentially extending its lifespan. Panels can also be easily removed if repairs are needed.
However, if your roof is already in poor condition, it’s best to address repairs before going solar.
Myth #5: Solar Energy Can’t Power My Entire Home or Business
Fact: A properly sized solar system can cover most, if not all, of your energy needs.
The key is to customize the system size based on your energy consumption, roof space, and location. Many solar users achieve near-total energy offset, and with solar battery storage, it’s even possible to use solar power 24/7 and during outages.
For businesses with higher loads, hybrid systems or partial offset solutions can still lead to significant savings.
Myth #6: Solar Panels Aren’t Environmentally Friendly to Produce
Fact: While panel production does have an environmental footprint, the long-term benefits far outweigh it.
Manufacturing solar panels involves energy and raw materials, but most panels offset their production emissions within 1–3 years. After that, they provide 25+ years of clean, emission-free electricity. Recycling programs for old panels are also growing, helping reduce waste and reclaim valuable materials.
Myth #7: Solar Energy Isn’t Reliable
Fact: Solar energy is one of the most reliable and predictable sources of power.
Solar panels have no moving parts and are built to last for decades. With proper system design, backup batteries, or a connection to the grid, solar can provide consistent, reliable power — even during power outages or at night.
Myth #8: Going Solar Means Going Off-Grid
Fact: Most solar installations are grid-tied, not off-grid.
You don’t have to disconnect from the utility grid to benefit from solar. In fact, grid-tied systems allow for net metering, which means you can send excess power back to the grid and receive credits on your electric bill. Off-grid systems are typically used in remote areas and require more equipment like batteries and backup generators.
