Pros and cons of solar energy

Solar panels promise lower electricity bills, energy independence, and a smaller carbon footprint. The real question homeowners are asking in 2026 is whether that promise still holds — now that the federal tax credit is gone and the cost math has shifted. Below is an honest breakdown of what going solar actually gets you, and what it costs, using current 2026 numbers.

Solar Energy Pros and Cons at a Glance

Now let's look at each of these in detail, starting with the pros.

PROS of Solar Energy

Reduced Electricity Bills

This one is a pretty straightforward, but weighty advantage. Going solar opens up new opportunities, such as generating your own electricity and offsetting your electric costs by selling the excess energy to the utility. Depending on your state, system size, and usage, solar panels can save homeowners roughly $100–$150 a month on average — which means close to zero electricity bill for residents of some states.4 With a grid-tie system, you can sell extra solar energy into the grid and gain credits. Check the map below to calculate how much solar panels might save you.

Higher Value of Your Home

No matter how much you love your two storey house by the ocean, nobody can guarantee you will live there till the last breath. There are plenty of circumstances which might force you to move house, so it's always a good idea to keep an eye on your property value.

Homes with solar panels now sell for about 6.9% more on average than comparable homes without them — roughly $25,000–$29,000 on a median-priced home — though the premium varies a lot by state:

Take state-level numbers as a directional guide rather than a guarantee for your specific home.

Energy Independence

Having solar panels makes you less reliant on the electric utility, which comes in handy in case of outages, for instance. It means you'll never have your bread half-baked, TV show half-watched, or clothes half-washed. Hybrid systems allow you to sell extra energy into the grid but also have a power outage protection in form of batteries — budget roughly $10,000–$16,000 for a single battery covering essential circuits, or $22,000–$40,000+ if you want enough capacity to back up the whole home.6

Eco-Friendly

Another advantage of solar energy is that it is clean and renewable. Opting for solar, you will join in the global fight against carbon dioxide emissions. On a cost basis alone, utility-scale solar now generates electricity at roughly 4–10¢ per kWh, which is in the same range as or cheaper than new natural gas plants (about 5–13¢ per kWh)7 — solar isn't just cleaner anymore, it's often competitive on price alone. In fairness, producing and eventually recycling panels does have its own environmental footprint, which we cover honestly in the cons section below.

Smart Long-Term Investment

The last but not the least thing to keep in mind: investing in solar energy can still pay off — just on a longer timeline than it used to. Solar renewable energy credits (SRECs) and net metering are two key benefits of solar that allow you to earn bill credits (or even extra cash) as your system produces electricity. Availability and generosity of both now vary a lot by state — some states, like California, have scaled back net metering compensation in recent years, so it pays to check local policy before you count on it.

With those incentives factored in, the realistic payback time for your solar panel system now runs about 8–12 years in most states. Once the PV system is paid off, your solar panels will keep generating free power for your home for the rest of the system's lifetime, typically another 15+ years.

Well, advantages were quite obvious and easy to find. Let's now have a look at the disadvantages of solar energy to make our review unbiased and objective.

CONS of Solar Energy

Solar panel costs in 2026: Prices & savings

There's no such thing as free energy. Even if production costs have fallen over the years, you still need to fork over a real sum for your PV system — and that sum is now higher for homeowners than it was in 2025, since the 30% federal tax credit no longer applies to residential installs. A typical 6-kilowatt system now runs about $14,500–$20,000 before any incentives, or roughly $2.40–$3.35 per watt.

Moreover, don't forget about installation costs and some extra expenditures, because you might want to buy a battery or an optimizer in addition to the basic kit. An off-grid panel system is a particularly big investment because of the size of energy storage that you'll need. The actual cost of a solar system depends on the state and the incentives that you qualify for — some state and utility-level rebates still exist even though the federal residential credit is gone.

Solar Panels Don't Work at Night

You'll sometimes see claims that moonlight can power solar panels overnight — it can't, really. Moonlight is hundreds of thousands of times weaker than sunlight, so a typical 300 W panel produces well under 1 W under a full moon, and most inverters won't even switch on at that level. In practical terms, night output is zero.

It is obvious, but yes, the sun doesn't shine at night, which is why solar is called an intermittent source of energy that can't be relied on 24/7. There's always a workaround, though: a cost-effective battery solution. Energy storage lets you keep the solar power generated during the day and draw on it at night, if needed — expect to pay roughly $10,000–$16,000 for a single battery covering the essentials, or $22,000–$40,000+ for whole-home coverage. Having a rooftop solar system with batteries also means protection power outages.

Weather Dependence

Modern solar technologies make it possible to collect solar energy even during cloudy and rainy days, though the efficiency of the PV system drops noticeably in those conditions. The power output specified by the manufacturer is achieved only on sunny and clear days, which can be rare in some states. So solar panel efficiency can differ meaningfully from state to state — which should be taken into account when estimating your own savings.

Additional Space

Power density is how much power can be derived from an energy source within a certain area, measured in watts per square meter (W/m²). If you buy a residential solar power system, you're unlikely to face a space issue, since a roof will almost always have enough room. It's more of a problem for large grid-scale solar installations, since solar panels have a lower power density than fossil-fuel plants — you need a much larger footprint to produce the same amount of energy a coal plant would.

Selling a Home With Solar Can Be Trickier Than Expected

Once the solar system is installed, it becomes an integral part of your house — and that cuts both ways when you sell. First, removing solar panels can be more expensive than installing them. Second, a net metering agreement is tied to the property, so you can't take your energy credits with you to a new place.

It gets more complicated if your system is financed rather than fully paid off. With a solar loan or lease, a buyer typically has to either qualify to take over the payments or you have to pay off the balance before closing — real estate agents increasingly point to this as a reason some solar homes take longer to sell. Owning your system outright (or making sure the loan is paid off before listing) avoids most of this friction.

Panels Slowly Lose Efficiency Over Time

It's a small point, but a fair one: solar panels don't produce the same amount of power forever. Most modules degrade by roughly 0.3–0.5% per year, so a panel that starts at 100% output is typically still producing about 80–90% of its original capacity after 25 years, depending on quality — which is why most manufacturers back a figure in that range with a 25-year performance warranty. It's a slow decline, not a cliff, but it's worth factoring into any long-term savings estimate.

Is Solar Worth It in 2026?

For most homeowners, yes — solar still tends to pay for itself well within the system's lifetime, especially where electricity rates are high and net metering is still generous. The honest caveat is that the payback period stretched out once the federal residential tax credit disappeared, so it's worth running the numbers for your specific state, roof, and utility rates rather than assuming a one-size-fits-all answer.
