Debunking 9 Common Solar Myths

Solar energy is advancing faster than ever, yet outdated information and myths about solar energy still persist. What was once true a decade ago may now be completely inaccurate. Unfortunately, these solar energy myths can lead homeowners to overlook the benefits of going solar.

From concerns about cost and efficiency to misconceptions about installation, misinformation may be keeping you from embracing solar power. Let’s debunk some of the most common solar myths so you can make an informed decision about whether solar is right for your home.

Solar Energy Myth 1: Solar Panels Are Too Expensive

One of the biggest solar energy myths is that solar panels are too expensive for the average homeowner. While that may have been true 15 years ago, the cost of solar has dropped significantly, making it more affordable than ever.

Most homeowners see a payback period of 5–10 years from electricity bill savings, yet solar panels typically last 30 years or more—meaning you could enjoy decades of “free” power. In states with high electricity rates, like California, Hawaii, and Massachusetts, the savings are even greater.

Plus, the 30% federal solar tax credit can help lower the upfront cost. For example, if your system costs $15,000, you could qualify for a $4,500 tax credit. Additional rebates may also be available depending on where you live.

Financing options make solar even more accessible. With the right loan, your monthly solar payments could be lower than your electric bill, leading to instant savings.

However, one myth about solar energy that holds some truth is that solar batteries don’t always pay for themselves quickly. While battery storage adds energy independence, it’s still a bigger investment that may not lead to immediate savings like standard solar panels do.

Solar Myth 2: Solar Panels Don't Generate Much Power In Cold Climates

One of the most common solar energy myths is that solar panels don’t generate much power in colder climates or during winter. While it’s true that solar production is higher in the summer due to longer daylight hours, that doesn’t mean your system stops working when temperatures drop.

In reality, solar panels work more efficiently in cooler weather. Since solar panels generate electricity from sunlight, not heat, colder temperatures actually improve efficiency—helping your system produce more power than you might expect.

Even in winter, as long as your panels aren’t covered in snow, they can generate plenty of clean energy. In fact, solar panels installed at a steeper angle (such as on pitched roofs) can still capture sunlight effectively when the sun is lower in the sky.

So, while shorter days mean slightly lower output, the idea that solar panels don’t work in winter is just another myth about solar energy.

Solar Panel Myth 3: Solar Installations Do Not Have Warranties

A common myth about solar energy is that solar systems don’t come with warranties. In reality, most solar panels, inverters, and batteries include manufacturer warranties, but the length and coverage depend on the brand. Many installers also provide labor warranties, ensuring peace of mind if something goes wrong.

Understanding these warranties is essential because they protect your investment. GreenLancer specializes in solar repairs nationwide and can help homeowners take advantage of manufacturer warranties when making repairs—potentially saving you thousands on replacement costs.

Solar Panel Warranties

There are two main types of solar panel warranties:

• Power Performance Guarantees: Solar panels naturally degrade over time, but manufacturers guarantee a certain level of output after a set period—often ensuring 80% or more of original capacity after 25 years.

• Product Warranties: These cover defects in materials or workmanship and typically last 10–25 years, depending on the manufacturer.

Solar Inverter Warranties

Inverters have different warranty lengths based on their type:

• String inverters usually have 5–15-year warranties, though some brands, like SolarEdge, offer extended coverage for an additional fee.

• Microinverters (mounted on each panel) often have 25-year warranties, ensuring long-term reliability.

If you ever need solar system repairs, GreenLancer’s expertise in warranty-backed repairs can help you maximize savings and keep your solar system running efficiently.

Labor & Service Warranties

Although solar panel and inverter warranties protect the equipment itself, they don't always include labor. However, many solar panel installation companies offer their own warranties on labor. The length of these warranties varies by the contractor but typically ranges between 3 – 10 years, but some solar panel installers offer longer warranties.

Solar Energy Myth 4: PV Systems Require A Lot Of Maintenance

A common solar energy myth is that solar panels require frequent maintenance. In reality, most photovoltaic (PV) systems are designed to be low-maintenance and highly durable. For homeowners with stationary solar panels and modern inverters, there’s very little required upkeep. Solar panels, racking systems, and inverters are built to withstand the elements and typically function without intervention. Systems without lead-acid batteries or moving parts require almost no homeowner maintenance.

Some solar tracking systems, which adjust panel angles for maximum sun exposure, require more upkeep since they have moving parts that can wear out over time. Likewise, traditional lead-acid batteries need regular maintenance to maintain performance. However, modern lithium-ion solar batteries offer a longer lifespan with no major maintenance, making them a hassle-free option—though they do come with a higher upfront cost.

Solar Energy Myth 5: Solar Homes Will Have Energy During A Power Outage

A common solar panel myth is that solar-powered homes will automatically have energy during a power outage. Unfortunately, most solar homes do not have power during grid outages unless they have a battery storage system. By design, solar systems automatically shut down production during an outage to protect utility company workers. If the system has batteries, the home will still have power.

Most grid-tied solar systems with batteries have a critical load panel. This allows homeowners to choose which circuits have power during an outage. Often, homeowners prioritize loads that prevent incurring loss first, such as the refrigerator.

Solar Panel Myth 6: PV Systems Will Store Excess Energy On Sunny Days

A common solar energy myth is that photovoltaic (PV) systems will store the excess energy they generate on sunny days. However, solar systems without batteries don't have the ability to store energy. The good news is that in most areas, homeowners can benefit from net metering. This program allows you to receive credits for any excess solar power you send to the grid.

For example, on sunny days, your solar system will produce more energy than you might need. Your solar panels will first power your home, and any leftover energy will be fed to the grid. At night, when your home needs power from the grid, you can use the credits you earned to offset those costs.

Solar Myth 7: PV Modules Will Damage The Roof

Another common solar panel myth is that solar panels will damage the roof. In many cases, solar panels can actually help protect your roof by shielding it from hail and UV damage. However, it’s important to ensure your solar panels are installed correctly to avoid any potential damage.

To make sure your system is installed properly, choose a qualified solar contractor with North American Board of Certified Energy Practitioners (NABCEP)-certified installers and licensed electricians. It’s also a good idea to work with a solar company known for its solid reputation and excellent customer service.

Solar Panel Myth 8: Homeowners Need A Special Insurance Policy To Cover Their System

A common solar panel myth is that homeowners need a special insurance policy to cover their solar system. While your solar panels are often considered a permanent improvement to your home, like a porch or a new roof, most standard homeowners insurance policies will cover the system as long as the coverage limits are adequate.

The key is to make sure your insurance policy offers enough coverage to protect your solar system. If the coverage limits are too low, they won’t fully cover the cost of the solar installation if anything were to happen. It's also important to review the terms of your policy or talk with your insurance agent to ensure your solar system is specifically included.

Solar Energy Myth 9: Homeowners Will Have No Electricity Bills

A common solar panel myth is that homeowners will have no electricity bills once they install a solar system. While it’s true that going solar can significantly lower your electric bill, it’s unlikely that you’ll have zero electricity bills. Even if your solar system produces as much energy as your home uses, you’ll probably still have some charges.

Utility bills typically have two parts: the supply charge and the transmission and distribution charge. Think of it like ordering pizza. The supply charge is like the number of pizzas in the order, while the transmission and distribution charge is like the cost of delivery.

For electricity, the supply charge depends on how much power your home uses from the grid, measured in kilowatt-hours. If your solar system generates enough energy to meet your needs, you could eliminate the supply charge. However, the utility company still charges a transmission and distribution fee, which is usually a flat rate every month for all customers. So, even with solar, you may still see that small fee on your bill, but your supply charge can be dramatically reduced.
