Solar; it's the Brighter Business Solution!


Are you curious about the benefits of transitioning your business to green energy? Let’s explore why this shift is not only environmentally responsible but also beneficial for your bottom line. Lowering your carbon footprint through green energy sources like solar electricity generation offers a multitude of advantages. Firstly, it enhances your appeal to customers, suppliers, and investors, showcasing your commitment to sustainability. As the market increasingly prioritises eco-friendly practices, this can give your business a competitive edge. Moreover, adopting green energy solutions like solar power presents a path to achieving net-zero emissions, contributing to a more sustainable future. By reducing reliance on fossil fuels, businesses can play a significant role in mitigating climate change.

Financially, the return on investment is compelling. Commercial solar electricity serves as a direct replacement for expensive business electricity, and any surplus energy can be sold back to the grid for additional revenue. This not only reduces operating costs but also diversifies income streams. Long-term security is another crucial benefit. With a commercial solar energy system, your business gains access to a reliable and sustainable energy source for decades. This shields you from fluctuating electricity prices and provides stability in an uncertain market.

At Celtic Green Energy, we’re committed to helping businesses achieve energy independence. By incorporating solar PV batteries and panels, you can reduce reliance on the national grid and safeguard against price fluctuations. Our team is here to support you every step of the way, providing expert guidance and tailored solutions to meet your needs. As Forbes highlights, “Solar energy offers businesses a sustainable and cost-effective alternative.” Embracing green energy isn’t just about reducing your environmental impact—it’s about securing a brighter future for your business.

Investing in renewable energy for commerce presents an ideal long-term solution, offering numerous incentives, including tax exemptions, reduced operating expenses, environmental advantages, and a diminished carbon footprint, thus aiding in meeting government emission targets. Solar power stands as a significant means to save on annual energy costs, complementing your electricity requirements throughout the year. During seasons of ample sunlight, solar energy can nearly fulfil your needs, while in darker months, you can lessen reliance on the national grid or opt for a solar battery system to store less expensive off-peak electricity for future use. Stored energy ensures a continuous power supply, mitigating any disruptions from national grid outages or energy rationing, particularly crucial for businesses reliant on energy, such as dairy or poultry units.

A renewable energy installation promises a substantial return on investment, providing free electricity for over 25 years, achieving an ROI of more than 12% annually, with installation costs recouped within 6-8 years. Additionally, you may explore land diversification with dual-purpose land usage, allowing for cattle or sheep grazing between Solar PV panels. For a comprehensive understanding of the benefits offered by a renewable energy installation, we recommend a personalised on-site survey conducted by our sales advisors.

Solar energy for business, naturally it's a great deal...

Wales Leading Soft Drinks Producer adds a Sparkling New Ingredient to it’s Drinks!

Tovali Celtic Green Energy April 2023

Leading independent Welsh drinks manufacturer Tovali has been an icon of Carmarthen life for the last 86 years and enjoyed by generation for their thirst quenching flavours. Keen to embrace modern technology they have added a sparkling new natural ingredient to the manufacturing process – sunshine!

With support from Carmarthenshire Economic Development Fund, Tovali had to address the need to cut their soaring energy costs which had risen from £13,000 to £53,000 in twelve months. “Our manufacturing process includes a fully automated production line that produces over 120,000 bottle of cordials and fruit flavoured squash for sale to major food and drink companies both in the UK and in Europe, the licensed trade and national supermarkets. We are totally reliant on electricity” states Eurwyn Harries, Managing Director. “Despite a healthy business, we were looking at serious economic uncertainty with the continuous rise in energy prices, it would simply be unsustainable. I know a number businesses have ceased trading due to the unprecedented challenges, but as family run business, with both a loyal employee and customer base,  I was not prepared to let that happen.”

Eurwyn outlined ”this was a clear opportunity for us to play our part in investing in renewable energy options for now and into the future, and forms a key part of our carbon footprint reduction activities as part of our Company Net Zero Plan by 2045.”

Eurwyn proactively contacted local Renewable Energy specialists, Celtic Green Energy from Gorslas to investigate the use of Solar power for their needs. They were chosen for their established experience and prudent regard to costs offering the best deal for our needs. MD Julian Jenkins and Sales Director Stuart Jupp undertook a thorough survey of the Tovali site to provide a comprehensive energy proposal where free solar energy would replace the need for costly national grid power, a cost saving of nearly £13,000! Tovali needed an effortless and professional installation that was required without any disruption to its daily manufacturing process. In early January, with a team of specialist installers, the roof of the Tovali building was soon clad in an array of the latest Solar Photovoltaic Panels that convert sunshine into free electricity. The whole system now generates enough electricity to power the energy intensive production line, creating a sustainable power source and in turn keeping Tovali drinks flowing freely for another day.
