Your Trusted Local Solar Energy Partner in Cork
At 021 Solar, we’re more than just another solar installer. We’re your long-term energy partners. Backed by the same trusted team behind 021 Electrician, we bring over 20 years of hands-on electrical experience together with specialist renewable expertise to help homes and businesses power their future with confidence.
As a locally rooted company proudly serving Cork City and County, we understand the real energy challenges property owners face. Rising costs, sustainability goals, and the need for dependable systems all matter. That’s why we carefully design and install solar solutions tailored to each property, from rooftop PV systems to battery storage and smart energy monitoring. Our goal is simple: to help you reduce energy bills, strengthen your energy security, and move toward a cleaner, more sustainable future.
Our reputation is built on safety, certified workmanship, and quality you can trust. Every solar system we install is completed by fully qualified, registered professionals who follow Irish electrical standards. We take pride in delivering systems that are built to perform reliably for decades, giving you peace of mind long after installation day.
Who We Are
Born from our established 021 Electrician business, 021 Solar is our dedicated commitment to renewable energy done properly. We are not new to the electrical industry. We are experienced professionals who have grown and evolved to meet the increasing demand for clean, reliable solar power across Cork and the surrounding region.
Our move into solar came from a simple belief: property owners deserve better than generic, one-size-fits-all systems. Every home and business is different. Energy usage is different. Goals are different.
That is why we take the time to design solar solutions around you, your property, your consumption, and your long-term plans. No shortcuts. No off-the-shelf packages. Just carefully planned systems built to deliver real performance and lasting value.
Our Approach: Complete Solar Solutions, Start to Finish
What sets us apart is our comprehensive, end-to-end approach. When you choose 021 Solar, you’re working with one company throughout your entire solar journey, with no subcontractors, no third parties, and no confusion.
We handle everything in-house:
This means no delays, no miscommunication between different trades and no unexpected costs. You have one point of contact who understands your project inside and out.
Premium Quality, Proven Performance
We believe in doing things properly the first time. That is why we use only proven, premium quality equipment designed to perform reliably for decades, not just a few short years.
Our carefully selected product range includes trusted global manufacturers such as DAH Solar, JA Solar, Jinko Solar and Aiko Solar panels, all chosen for performance, efficiency and long-term durability. For inverter and battery technology, we install premium systems from Sigenergy and GoodWe. For customers who want a showcase-level residential setup, Sigenergy is a standout option: its SigenStor platform is positioned as an AI-optimised 5-in-1 home energy system, with an all-in-one design approach, strong smart energy management and a premium user experience through the mySigen app.
To ensure every installation meets the highest safety standards, we use professional-grade Hager electrical equipment throughout. For customers preparing for electric vehicles, we supply and install high-quality EV chargers, and we can design a wider system so solar, battery storage and smart charging work together as one integrated, future-proof energy setup at home or at your business.
This is not about choosing the cheapest components. It is about delivering maximum long-term value, performance and reliability so your investment continues to work hard for you year after year.
Our Commitment: Built to Last, Backed for Life
Here is something you will not find with many other installers. Every system we install is backed by our 30-year workmanship warranty. This is not just confidence in the quality of our work. It is our commitment to stand behind every installation for as long as you own your property.
When you combine that with the strong manufacturer warranties on our premium components, you get genuine long-term protection and complete peace of mind. Your solar investment is built to last and fully supported for decades to come.
Custom-Designed Systems for Real-World Performance
Every property is different, and every energy requirement is unique. That’s why we never offer standard packages or one-size-fits-all solutions. Instead, each system we design is completely customised based on:
Whether you need a ground-mounted system, rooftop installation, carport system, battery storage solution, or commercial-scale setup, we design for optimal performance, not just the easiest installation.
