Are solar panels worth it or not? A balanced review of the true costs and savings

Are solar panels a good investment? With energy prices climbing and environmental concerns on the rise, many are asking if switching to solar power is a smart financial move. If you’ve been pondering whether solar panels are worth the cost, you’re not alone.

The decision to install solar panels involves weighing several factors, including the upfront investment, potential savings, and long-term benefits. To help you navigate this choice, it’s essential to understand the pros and cons of solar panels. Are they truly a cost-effective solution, or just a passing trend?

On this page, you’ll learn:

• A detailed look at whether solar panels are worth it or not to help you assess their value.
• The financial advantages of solar panels, including savings on your energy bill and available incentives.
• How to determine if solar panels are a good fit for your specific situation and goals.

By the end of this page, you’ll have a clearer picture of whether solar panels are a worthwhile investment for you.

Let’s dive into the details!

When are solar panels worth it?

If you’re still stuck in limbo wondering whether or not solar panels are truly worth the investment, considering the following factors can help you make your decision:

1. The more sunlight your location receives, the better

• Do you live in a region that enjoys ample sunlight year-round?

Location matters to some extent when it comes to the performance of solar panels.

It’s strongly influenced by the amount of sunlight that your location receives. Regions south of England experience more sunshine and typically benefit from much faster returns due to the higher energy production.

That said, even on cloudier days, areas like Scotland, can still benefit from solar panels. Of course you won’t get as much energy output on overcast days, the panels will continue to produce electricity.

In these cloudier regions, it could take a bit longer for you to break even on your investment. But keep in mind, you’ll still see a reduction in your energy bills over time. Additionally, it’s worth noting that the panels still produce power during the winter months, even if it’s at a reduced rate because of shorter daylight hours.

Overall, while sunnier climates can give you faster returns, even less sunny regions in the UK can still benefit from significant long-term savings, especially with energy costs on the rise.

2. Your roof’s characteristics, combined with a well-planned solar panel installation by a professional, positively impact the efficiency of your solar setup

• Orientation: Does your roof face south, southwest, or west?
• Space: Is there enough space for a solar panel system?
• Shade: Is your roof free from obstructions like trees or buildings that cast shadows?

Your roof actually plays an important role in determining whether or not solar panels are a good investment. Solar panels tend to work best on south-facing roofs. This is because they get the most direct sunlight throughout the day.

A roof with a tilt of 15 to 40 degrees is also ideal as it will allow for optimal solar energy absorption. However, if you’re wondering where to install solar panels, don’t count yourself short if your roof faces east or west, you can still install solar panels, though they may be slightly less efficient.

Additionally, shaded roofs, resulting from nearby buildings, trees, or structures will further affect the effectiveness of the system. In cases where shading is an issue, additional installations, such as angled mounting or inverters can help to optimise energy generation, although this might increase the overall cost. Microinverters can be especially useful, as they allow each panel to operate independently, which ensures maximum efficiency, even if some panels are shaded.

DID YOU KNOW… Did you know that that even if your roof isn’t perfectly positioned, custom solutions do in fact exist to optimise your energy capture? You’ll just need to keep in mind that these adaptations may increase the expenses and extend the payback period.

3. The more electricity you use, the more you’ll benefit from solar panels

• Do you use a lot of electricity, and are the electricity rates in your area high?

If you live in an area where the electricity rates are expensive and have high electricity needs, you’ll save more, and the solar PV system will quickly pay for itself.

However, if your energy system is typically low, it could take a bit longer to see these savings as your bills aren’t as high to begin with. Heavy electricity users, especially daytime users, can greatly reduce their reliance on the grid and avoid the rising energy prices.

4. Government grants and schemes can lower your initial cost

• Are you eligible for any tax incentives or rebates?

In the UK, there are various solar panel grants and funding schemes that can make solar panels more affordable to homeowners.

Available solar panel funding options

One scheme we previously mentioned is the ECO4 scheme, aimed at improving energy efficiency in low-income households. This scheme can provide financial assistance for solar panel installation with eligibility extending to households earning less than £31,000 or homes that are energy inefficient.

Moreover, the Home Upgrade Grant (HUG2) provides up to £10,000 for households in select local authorities. This covers energy-efficient home improvements such as solar panels.

This grant can be very beneficial for homes that have low Energy Performance Certificate (EPC) ratings (D-G), as it makes them much more accessible to homes that otherwise could not afford them.

There are other options out there such as financing schemes that are offered by some panel installers. They can include loans or payment plans and help to spread the cost over the course of several years which can make the cost of solar more affordable upfront.

For instance, the Home Energy Scotland Grant is available in Scotland, Wales, and Northern Ireland and provides up to £6,000 in funding for solar.

Additionally, there are crowdfunding or community solar programs which can be an innovative way to minimise costs.

These involve multiple households or communities coming together to share the investment in a large solar installation. This gives way for a more widespread adoption of renewable energy at lower individual costs.

5. Net metering turns excess solar energy into profit

• Are net metering programs available in your area?

Net metering allows you to earn extra credits or receive financial payouts based on the excess energy your system produces. This means that any extra electricity your panels generate can be sold back to the grid.

The more energy you use can help you recoup your costs faster. In areas with net metering, this feature truly boosts your overall savings by turning your solar system into a money-saving and possibly money making investment.

IS IT WORTH INSTALLING SOLAR PANELS? If you answered ‘yes’ to most of these questions, solar energy is likely a great investment for you. If you’re uncertain, speaking to a solar expert can provide tailored advice based on your specific situation and renewable energy goals.

Why are solar panels not worth it for all homeowners?

Solar panels can be very advantageous for many, but they might not be the best option for everyone. Here are some reasons why they may not be suitable:

1. High upfront costs

Undoubtedly, solar panels require a significant amount of money upfront. Although there are grants and financing options available, this initial outlay can still be a challenge for some homeowners.

This is why many installers are now offering payment plans that help spread the cost over time. That, along with the rising energy prices make solar the more cost-effective solution in the long run.

Additionally, the UK’s zero VAT on solar installations ensures that upfront solar panel costs are lowered, which makes the initial investment much more manageable.

2. Weather & climate deterrents

It’s true that domestic solar panels perform their very best in the sunniest conditions and that cloudy or short winter days can affect their efficiency. However, panels still produce usable electricity even on cloudy days, albeit at a lower rate.

What’s great about the advancements with technology and solar is that modern panels are much more efficient and can still generate power even in low-light conditions.

This means that even in cloudier regions of the UK, a solar panel system is producing enough energy to make a difference. What’s more, there’s still the potential to save over time, making them a viable option.

3. Your roof isn’t suitable for solar panels

Perhaps your roof is older, or maybe you have less roof space, or even heavily shaded, and in such cases, a solar installation might not be the most ideal option. In fact, roofs that face north are typically shaded by trees or buildings tend to generate less electricity.

However, don’t lose hope! For less-than-ideal roofs, there are solutions such as using microinverters or ground-mounted solar panels to truly optimise energy production. With the right setup from an accredited solar panel installer, even shaded roofs and those with less roof space can benefit from solar.

4. Your electricity costs are already low

If you have a small home, energy-efficient appliances, or your electric bill is already low, installing the average solar panel system might not deliver quick returns. The solar panel payback period will be longer, and the savings may take more time to accumulate.

Even if your current circumstances and bills are proven low, investing in solar energy now is the protection you need for the future.

Energy prices on electricity bills will continue to rise.

So when considering, “Are solar panels worth it?”, remember that with solar panels installed, you reduce your reliance on the grid, so that you’re less vulnerable to sudden hikes in electricity bills.

5. You plan to move or sell your home

If you have plans to move soon, a solar energy system might not be worth the investment.

The upfront cost of solar panels can take several years to recoup, and if you leave before hitting that break-even point, you might miss out on the full benefits.

When thinking about this, it’s important to remember that adding panels to your residence increases the value of your home. Properties with solar tend to sell faster and at higher prices.

However, this is only true if the system is fully paid off. If you’re financing your solar panels through a loan, you’ll likely need to settle the remaining balance upon selling the house, which could complicate the sale.

Moreover, transferring the PV system to a new home is notoriously expensive and impractical, as solar panels are intended to remain fixed in place for their entire lifespan.

That being said, if you own the system outright, the added value and energy savings can still make your home more attractive to potential buyers​.

6. You’re not eligible for grants and incentives

The cold, hard truth about it is that not every homeowner will qualify for grants or incentives, and this alone can make the initial investment seem less attractive.

That said, even without grants homeowners who believe in their renewable goals are resilient! Even without grants, many installers provide excellent solar panel financing options so that you can pay over time. Moreover, since we know that the cost of electricity will continue to soar, the panels will indeed save you money eventually, even without the initial financial support.

How much do solar panels save?

To quickly estimate just how much you can save with solar panels, use our soly calculator tool. This easy-to-use tool helps you calculate your potential savings based on your energy consumption, system size, and location.

Indubitably though, when installing solar panels, you can save a significant amount on your electric bills. This is especially true in regions that have higher energy rates, as mentioned. On average, homeowners save up to £1,300 per year, on average, depending on the size of their solar panel system and local electricity prices.

That said, larger solar panel efficiency systems tend to provide even bigger savings and if you produce more energy than you use, you can always sell it back to the grid through the Smart Export Guarantee (SEG).

The Smart Export Guarantee payments are based on the surplus energy your solar panel system generates, which can further boost your financial returns from the solar PV system.

Additionally, the UK’s current 0% VAT policy on installing solar panels makes these investments even more affordable. Right now, if you find yourself wondering, “are solar panels worth it?”, with the 0% VAT on solar panels, the savings alone at this time speak for themselves:

• Savings on 2 kW with Zero VAT: £900
• Savings on 3.5 kW with Zero VAT: £1,400
  
• Savings on 5 kW with Zero VAT: £2,200

Furthermore, when you cut your energy bills, these panels also minimise your reliance on the national grid which keeps you safe from any future rise in energy prices. Over time, the solar arrays can result in greater long-term savings all while reducing your carbon footprint.

How long does it take to break even on solar panels?

The payback period for solar panels in the UK typically ranges from 7 to 25 years, with some homeowners breaking even in as little as 14 years. However, with Soly, the average return on investment is around 7-8 years.

So, the ROI (return on investment) can vary. This depends on factors like system size, installation costs, and available incentives. With larger solar panels in place, you’ll find better returns. This is due to the greater energy generation and the potential for higher savings.

But that’s not always the case.

In limited-size roofs, smaller panels with higher efficiency can be selected to deliver the same levels of electricity and savings.

Additionally, the SEG can also reduce the payback period and help you break even. This scheme does this by generating additional income from your excess electricity generated, as mentioned earlier.

For instance, a typical 3.5 kW solar system can pay for itself within 7 years:

• Total cost of solar system: £7,000
• Incentives and grants: £2,000
• Net system cost: £5,000
• Annual savings:
  • Electricity savings: £500
  • Selling excess energy (SEG): £200
• Total annual savings: £700
• Payback period: £5,000 ÷ £700 = 7 years

After your solar panel payback time, you can continue to enjoy the reductions on your energy bill and the income you make from exporting excess energy, which makes the solar panels worth it and without a doubt, a solid long-term investment.
