10 Reasons Why Solar Is Your Next Best Investment

Posted on December 2, 2025

A new year is the perfect moment to take control of your energy future, and going solar is one of the smartest and most future-proof decisions you can make for your home.

Most homeowners who switch to solar see their electricity bills drop by around 50% per year, depending on energy use and the system design, and solar panels generally pay for themselves within 5-7 years.

While the upfront investment can be considerable, we offer solar panel financing to make clean, green energy more accessible.

And if saving money and reducing your carbon footprint weren’t reasons enough to join the rooftop solar revolution, extreme weather events like Storm Éowyn and volatile global energy markets have left many of us exploring ways to increase our energy resilience and independence.

And solar is a great start.

Here are 10 reasons why going solar is your next best investment.

1. Cut Your Energy Bills

Solar PV is a long-term investment that can power your home for decades with reliable, clean energy.

Solar panels can help cut your electricity bills by 50% a year, while also allowing you to earn credit from your electricity provider by selling excess power back to the grid.

But not only are you saving on bills, you’re protecting yourself against inevitable electricity price increases and potential energy shortages in the future.

2. Reduce Your Carbon Footprint

Solar is 100% clean energy. Over 25 years, even a small solar system can save more than 20 tonnes of CO₂ and generate more than 36,000 units of electricity.

And every unit of electricity generated by a solar PV system reduces the amount of CO₂ emitted from conventional power stations.

3. Built To Fit Your Life

Whether you’ve got a roof, a shed, or spare space on the ground, there’s a solar setup that works for you.

Our team designs every system to suit your home, your lifestyle, and your energy goals.

There’s no one-size-fits-all approach at Ohk energy; every system we design and install is built around you and we pride ourselves on that expertise.

We’ll also be on hand long after to support you throughout your entire solar journey.

4. Government Grants

Thanks to government grants, the 0% VAT rate, and smart technology, solar systems are now more affordable and efficient than ever.

The maximum SEAI grant for residential solar panels is €1,800 and the best bit is we deal with all that for you.

5. Low Maintenance

One of the most reassuring things about solar PV systems is that they’re low maintenance.

Most systems last up to 30 years, and many keep working well beyond that with minimal drop in output.

But proper care, including annual solar PV health checks, occasional cleaning, routine visual checks, and timely repairs help protect performance and warranties.

A health check typically only takes 1-3 hours depending on your system’s size, complexity and accessibility, and outside of annual check-ups, we’d recommend scheduling one if you notice higher than expected electricity bills, a drop in output, an error message on your inverter, or when you have concerns (such as after an extreme weather event).

We also provide health checks on newly-installed systems for your peace of mind, and we check any system, not just those we’ve installed.

6. Increase Your Home’s Resale Value

Having solar panels on your home makes it more attractive for buyers because solar helps lower electricity bills, increase energy efficiency and resilience, and lower your carbon footprint.

With rising energy costs and increasing climate targets, solar installations are becoming more attractive to buyers.

7. Finance Plans

We believe that the transformative power of solar should be available to all, so we have partnered with Finance Ireland for financial solutions designed to work for you.

Finance Ireland are Ireland’s largest non-bank lender since 2002, and they offer tailored financial solutions to meet your needs.

That means low upfront payments and monthly repayments you can afford.

8. Warranties And Guarantees

Solar is a big investment, and that’s why panels come with big guarantees.

Our solar panels are backed by a 25-year product warranty and a 30-year performance manufacturer warranty.

And for even more peace of mind, we also provide a 5-year workmanship warranty as standard on all our solar panel installations.

That’s why it’s so important to choose a trusted installer who uses high-quality panels and components.

At Ohk energy, we design every system to last and to keep performing efficiently for decades to come.

And our expert aftersales care means we’re here to help long after the install.

We’re also triple ISO accredited and a registered SEAI installer. Peace of mind guaranteed.

9. You Can Heat Your Hot Water

No more worrying about whether you left the immersion on!

10. Building Your Energy Resilience

Extreme weather events like Storm Éowyn and volatile global energy markets have left many of us exploring ways to increase our energy resilience and independence.

And solar has emerged as a valuable investment.

Yes, governments, policymakers and big businesses have a huge role to play in global resilience.

But installing solar and storage options to generate your own electricity is one way you can take power into your own hands.

By generating and storing your own energy, you can help relieve pressure on the grid and you’re less vulnerable to price hikes and market shocks.
