As homeowners increasingly consider solar energy as an alternative to traditional power sources, it’s natural to have questions about how it all works. Whether you’re curious about costs, installation, or long-term benefits, we’re here to provide the answers you need. At Erickson Electric Company, we’ve helped many Minnesota residents make the switch to solar, and we’re here to address the most common questions we get from homeowners like you.
How do solar panels work?
Solar panels work by converting sunlight into electricity using photovoltaic (PV) cells. These cells absorb sunlight and generate direct current (DC) electricity, which is then converted into alternating current (AC) by an inverter, making it usable for your home. When your panels produce more energy than you need, the excess can be stored in batteries or sent back to the grid.
How much do home solar panels cost?
The cost of a solar installation can vary depending on the size of the system and your home’s energy needs. On average, Minnesota homeowners can expect to pay between $10,000 and $25,000 for a residential solar system before incentives.
However, financial incentives like the federal Investment Tax Credit (ITC), which allows you to deduct 30% of the installation cost from your federal taxes, can significantly reduce this amount. Minnesota also offers state-level rebates and incentives, making solar more affordable than ever. Plus, solar systems generally pay for themselves over time through reduced energy bills.
How long does it take to see savings on my energy bill?
Homeowners typically start seeing savings as soon as their solar panels are operational. In fact, depending on your energy consumption and the size of your solar system, you could see a noticeable reduction in your energy bills within the first month.
Over time, as energy prices rise, your savings will only grow. Many solar systems pay for themselves within 6-10 years, after which the energy your panels produce is essentially free.
Do solar panels work in Minnesota’s climate?
Yes! Despite Minnesota’s colder climate and snowy winters, solar panels work effectively here. Solar panels rely on sunlight, not heat, to generate electricity, and they’re designed to operate in various weather conditions.
In fact, solar panels tend to perform better in cooler temperatures than in extreme heat. Snow can actually help clean panels by removing dirt as it melts, and Minnesota’s long summer days make up for shorter winter ones, ensuring that panels generate plenty of energy throughout the year.
Do solar panels still work when it's cloudy, raining, or snowing?
Yes, solar panels still work during cloudy, rainy, or snowy weather, though their efficiency may be reduced. They rely on sunlight, not heat, so even when it's cloudy, panels can capture indirect sunlight and continue generating electricity. In snowy conditions, panels can produce electricity as long as they're not covered in snow, and they often melt snow quickly due to their dark surface and angle.
Do I need to maintain my solar panels?
Solar panels require very little maintenance once installed. They’re designed to withstand the elements, from wind and rain to snow and ice. Most systems come with warranties lasting 20-25 years, so any defects in the panels themselves will typically be covered.
That said, it’s a good idea to have your system checked periodically to ensure everything is functioning efficiently. An annual inspection can help you spot potential issues early and extend the life of your system.
Occasionally, you may want to clean your panels if dirt, dust, or debris accumulate, but rain usually handles this naturally.
What happens if my solar panels produce more energy than I use?
If your system generates more energy than you use, you can store it for later use with a battery storage system or send it back to the electrical grid. Minnesota has a net metering policy, which means you’ll receive credits from your utility company for the extra energy your panels generate.
These credits can be used to offset future energy costs, such as on cloudy days or during nighttime hours when your system isn’t producing electricity.
How long do solar panels last?
Solar panels are designed to last for 25-30 years, with many continuing to produce electricity well beyond that. Over time, the efficiency of the panels may decrease slightly, but even after 25 years, most systems still operate at around 80% of their original capacity.
Inverters, which convert solar power into usable electricity, may need to be replaced every 10-15 years, but this is a relatively minor cost compared to the long-term savings solar energy offers.
Can I finance my solar installation?
Yes! Many homeowners choose to finance their solar installations, making the upfront costs more manageable. Solar loans, leases, and power purchase agreements (PPAs) are all options that allow you to pay for your system over time while still benefiting from immediate energy savings.
At Erickson Electric Company, we can help you explore your financing options and find the best plan for your budget.
Is solar energy a good investment for my home?
Absolutely! Solar energy can significantly reduce or eliminate your monthly energy bills, increase the value of your home, and reduce your carbon footprint. With state and federal incentives, the initial cost of going solar has never been lower. Plus, as energy costs continue to rise, the financial benefits of generating your own electricity become even more pronounced.
Many Minnesota homeowners find that solar not only makes sense from an environmental standpoint but also provides a strong financial return on investment.
