Are Solar Panels Worth It? Here's How To Tell If They're Worth It For You (2024)

Solar power is an eco-friendly renewable energy source plentiful in sunny locations. The technology works by converting sunlight into usable energy in the form of electricity or heat.

Solar technicians install different types of solar panels (typically monocrystalline and polycrystalline) on roofs with photovoltaic (PV) cells that harness and transform sunlight into sustainable energy with the potential to power an entire home––lighting up rooms, running appliances, heating water and keeping everyone warm and cozy on cold days and nights.

Solar panels work when the sun’s rays hit a solar panel, causing the photovoltaic (PV) cells within the installed panel to absorb the sun’s energy. The absorbed energy then ignites electrical charges within the cells that move until they generate an electrical current that we use as electricity.

The electricity generated from the solar panels moves along a conductive wire to a device called an inverter. The inverter transforms direct current (DC) electricity produced by the solar panels into usable electricity known as alternating current (AC) electricity that we can use for lighting, appliances, and other home systems.

The national average for solar panels costs about $16,000 for a 5 kilowatt system before tax credits. However, some solar panel systems can run more than $35,000. The exact price a homeowner will pay depends on a number of variables, including geographic location, home size, solar system size and solar installer rates.

It’s important to remember that the investment for a solar system covers more than just the panel costs.

On the bright side, solar panel costs have decreased by more than 50% in the last 10 years, according to the Solar Energy Industries Association (SEIA). The typical solar energy system is priced around $16,000, although the actual cost fluctuates depending on a system’s size, regional rates, and the solar installer you choose. The easiest way to find an accurate price is to speak with a local installer.

Solar Financing Options

Your final cost will also hinge on the solar financing route you take. For homeowners who don’t have the capital to invest in a solar system outright, there are other financing options to consider. However, some of them come with drawbacks.

Finance Yourself

Homeowners opting for an upfront payment (aka cash) for their solar system can expect a higher return on investment. They will bypass interest charges and are eligible for solar rebates and incentives such as the 30% solar tax credit for photovoltaic solar panel installation.

Solar Loans

Solar loans can be a good option if you want to own your system, as they still make you eligible for incentives, but you won’t have to pay for everything upfront. These loans work similarly to loans like you’d see for cars or other home improvements, so you’ll need to compare solar loan providers, rates and other factors. However, it’s important to note that the accruing interest of 4% to 7% over time can dramatically increase your total costs.

Solar Leases and PPAs

These options provide homeowners the opportunity to lease systems instead of owning them outright. A solar lease is an agreement between the homeowner and the solar provider that allows them to install solar panels on their house at minimal to zero costs for a fixed monthly payment. A solar PPA enables homeowners to purchase power from a solar company or a third party at a fixed rate per kilowatt hour. Although solar leases and PPAs are less expensive upfront, homeowners are ineligible for rebates and incentives, which can help them save 30% on installation costs.

By doing some math, we can roughly estimate how much solar panels save the average homeowner. Once you calculate the initial investment for a solar power system and its energy production capacity, you can hypothetically estimate the potential annual savings on your energy bills.

The lifespan of solar panels is around 25 to 30 years. Homeowners typically recoup their investment in around eight to 12 years. This means after paying off your solar panels, you’ll likely benefit from an average of more than 15 years of savings on utility bills.

Here’s an example: Let’s say you pay the national average of $16,000 for solar panel installation. With the 30% tax credit ($4,800), your average cost will equal $11,200. If you save an average of $100 per month on electricity after the payback period, that’s $1,200 per year. Multiply that by 16 years, and you’ve saved $19,200.

There are, however, some cases when solar panels don’t yield the return on investment some homeowners expect because of faulty equipment, less-than-optimal sunshine and more. To discover a solar panel system’s expected production rate in your area and potential output issues, you’ll likely need to reach out to a professional. Ask people you know for recommendations to find the best solar companies in your area. You can also find customer reviews of solar companies on the Better Business Bureau website and review sites online.

Before investing in going green, it’s important to know the advantages and disadvantages of solar panel installation to help you decide if solar is a worthwhile investment for your home. Consider the following pros and cons that provide some insight.

Pros of Going Solar

There are many benefits of installing solar panels to your home. These include:

Reduces your Carbon Footprint

Every kilowatt-hour (kWh) of solar generated by your panels can help reduce greenhouse gas emissions such as CO2, and toxic pollutants like sulfur oxides, nitrogen oxides and particulate matter, according to the Department of Energy.

Saves Money on Utility Bills

While installing solar panels may require an initial investment, homeowners will experience savings in the long term. That also means reduced electricity bills and no more surprise high bills to deal with.

Allows You To Participate In Net Metering

Many states have net metering programs that allow you to profit from unused energy. That means homeowners get credits for the electricity they add to the grid from their panels.

Federal, State and Local Tax Incentives

Customers will receive a 30% federal tax credit just for adding solar panels to their homes. While every state is different, homeowners can save even more money with local state incentives and rebates.

Cons of Going Solar

Despite the many advantages of adding solar, there are some negatives:

High Upfront Investment

Depending on the state that you live in or the company you go with you may have a high initial upfront cost. Incentives and rebates can help with costs but not all states offer those.

Requires Ample Sun

If you happen to live in an area that gets severe cold weather you may not be getting the full benefits from your solar panels.

Expensive Installation and Maintenance costs

Installation can be expensive, depending on the company you go with, and whether you have a strong warranty. And while panels do not require too much maintenance, any issues with your panels requiring repairs or maintenance could be costly.

Some Financing Options Not Eligible for Incentives and Rebates

Most solar installation companies provide you with different financing options, however, not all financing options, such as leasing, allow you to take advantage of incentives and rebates.

To understand if solar panels are worth it for your home, it’s vital to consider the following factors.

• Clear view of the Southern sky: For solar energy to perform at optimal levels, your house will need an unobstructed view of the Southern sky. High buildings and trees that block sunlight can directly impact your solar output.
• Size of solar system: If you have a large house and wish to offset 100% of your electrical usage, you’ll need more solar panels, which will increase the price of your solar system.
• Local electricity rates: Electricity rates vary across the country. Knowing your local rates will let you know your potential savings.
• Whether you lease or purchase your system: Homeowners who purchase their system will benefit from tax incentives because they own their system. If you lease your system, you might have a lower upfront cost, but you won’t be eligible for those great solar tax incentives.
• Frequency of power outages: If you have frequent power outages due to storms and inclement weather, you’ll need a battery backup to store your energy for long downtime periods, which is an additional expense.

If you desire to adopt a greener lifestyle to help the planet and live in a climate with ample sun exposure, installing solar panels on your home can do double duty by helping the environment and earning you money by selling the surplus of energy back to the grid.

While the costs of solar panel installation have decreased over the last decade, maintenance can still be a significant expense for some homeowners. To find out if you’re a good candidate for solar energy, here’s how to find the best solar installers near you.
