For the Tudge family who rear free-range Berkshire pigs and then sell their succulent meat products across Shropshire and Herefordshire, keeping an eye on the bottom line is essential. In the 1990s they choose to cut out the middle man and sell their products direct via Farmers Markets and local shops. With rising energy costs, G&R Tudge decided in 2024 to install solar PV with the view to offsetting a sizeable proportion of their electricity bill.

“Solarkinetics was recommended to us and that’s how we like to work, through personal contacts,” said Guy Tudge, joint owner of the family-run business. “When Solarkinetics visited, Gordon Yule explained everything in easy to understand terms. We have a 3-phase electricity supply here at the farm so it was a bit more complicated than the usual electrical set-up.”

Solarkinetics took care of gaining the necessary pre installation approvals and post installation commissioning with the Distribution Network Operator (DNO).

On the roof of a building near to where the butchery, cool rooms and prep room/kitchen are located, 35 x 410Wp REC Twin Peak 5 solar panels (14.35kW) were installed, connected to a 12.5kW SolarEdge Home Wave three-phase inverter. This provides on-site power requirements with any excess exported to the grid.

The cool rooms require more electricity to run over the warmer summer months, fortunately this is when the solar panels are producing their maximum yields.

“When the guys came to do the install, they came when they said they would, they were obliging and left the site neat and tidy – they were a real pleasure,” continued Guy. Over the first 5 months the system has been running, starting May 2024, solar has met 40% of electricity usage.

“I’m happy with that. We’ll let this run for a year and ask Solarkinetics to analyse our consumption versus power output from the solar to see if installing batteries that can store excess power for use on cloudy days would make financial sense.”

The Tudge family decided to add solar PV to two of the farmhouses on the farm as well. Now everyone is benefiting from “free” electricity, even the pigs! When the weather is at its worst and the fields are like the Somme, the rare-bred pigs move into sheds where they live in family groups on thick beds of straw. Happy pigs, no wonder their meat tastes so good.

When Hereford Enterprise Zone Ltd in conjunction with Herefordshire Council decided to rebuild the former Munitions Building in Rotherwas, Hereford, as a nod to its unique history, the emphasis was on build sustainability. The resulting building is the Shell Store, an incubator and business networking  centre in Skylon Park, Hereford Enterprise Zone that helps start-ups and growing businesses with office space and support services.

Rotherwas was home to one of the largest explosive filling sites in the UK during the First World War and again was active in the Second World War. The aptly named Shell Store is one of the last surviving buildings of the 370 buildings that existed over the 300-acre site.

Melcon was the electrical contractor in the rebuild and Solarkinetics secured the solar PV installation work after a robust procurement process. The sawtooth roof of the Shell Store brings natural light into the building on the north facing predominantly glass elevations while solar panels were installed on the south facing elevations of the metal clad roof.

246 x 320Wp REC Twin Peak 2 solar modules were fitted to the Euroclad roof using Sunfixing mountings. Power Optimisation boosts power output by enabling a pair of modules to work independently to produce maximum power, despite shading on one panel pair that would otherwise reduce the output of all panels in the same string. The inverter chosen was a SolarEdge 82.8kW three-phase Synergy inverter, installed in the plant room.

The building provides a flexible workspace offering co-working, office space and meeting rooms for freelancers, start-ups and small businesses. Around 30 of the rental offices are occupied and in the centre of the building is the Munitions Café, a great place for networking. 

Since the solar PV system was switched on in 2021, it has generated 124MWh of electricity with 98% of power produced being consumed onsite. Depending on the time of year, overall solar power generation contributes 25-30% of the power requirement in the building.

“Herefordshire Council saw this project as a chance to show leadership in sustainability and the installation of the solar PV system was an important part of the jigsaw to achieving this,” said David Wright, Head of Economy and Regeneration at Herefordshire Council. “Solar generated power is making a valuable contribution to reduce our electricity costs in the building.”

The Courtyard in Hereford is a multi-arts centre with Café and restaurant that welcomes 350,000 plus visitors each year. Its large flat roof is the perfect space to install solar without affected the visual appeal of the large glass fronted building.

The Courtyard started its solar journey in 2015 when Solarkinetics installed 30kWp of solar on two of the higher flat roof areas, generating 10% of its total electricity consumption. The system comprised 120 x REC 250W Peak Energy solar panels with a Sunny Tripower 15kW 3 phase inverter.

Then in 2019, The Courtyard joined forces with other arts and cultural organisations in the UK and Herefordshire Council to declare a Climate and Ecological Emergency. Since then, it’s been on a path to not only reduce its carbon emissions but also its consumption to sustainable levels and encourage others to do so.

“Our motivation for installing solar is to reduce our carbon footprint and also to save costs as our electricity bill is rather large,” said Phillip Pearcy, Head of Operations at The Courtyard. “In 2022, we installed an additional 31kWp of solar bringing the consumption of 300,000kWh per year down to 240,000kWh.”

Now, both solar installations contribute 20% to the electricity requirement in the building.

The 2022 installation comprised 84 x 370Wp REC Twin Peak 4 solar panels installed on the main flat roof space plus 1 x SolarEdge 30kW 3 phase inverter. The break even for the second installation is forecast to be in 2027, just 5 years.

The second solar project went out to competitive tender and Solarkinetics won, helped by a positive experience with the first solar installation in 2015. “It’s great to support a family business and a local contractor, at that,” continued Phillip. “The installation was hassle free and we found the Solarkinetics team friendly and knowledgeable with a “can do” attitude which was much appreciated.”

The second 31kW of solar was installed with part funded by the EU European Regional Development Fund and match funded by Theatres Trust.

The Rotherwas Service Station selling BP petrol and diesel does a roaring trade providing “fuel” for workers and their vehicles during the working day. The owner, Mohammed Ahmed, decided to expand in 2017 with a new larger building providing more than just a convenience store. There’s hot, freshly baked food for the hungry workers of Skylon Park, Hereford Enterprise Zone with an emphasis on supporting local food suppliers.

Mohammed wanted to offset the higher running costs by installing solar panels and generate their own electricity to power the new building, its fridges and ovens.

To capture as much of the energy from the sun as possible the main roof was orientated south and built at the optimal angle of 30°. “I got a couple of local companies to quote for the solar installation and Solarkinetics really stood out as the best option. Gordon Yule, who came out to do the site survey and design the system, was flexible and very customer focused, looking at how best to meet my requirements,” said Mohammed.

COVID lockdowns delayed Mohammed’s plans for the solar system but when the price of electricity started to skyrocket in 2022, the move to renewables took on a new impetus.

In total 108 solar panels were installed, covering the south facing main roof plus the forecourt canopy above the fuel pumps. “The installation team were professional, the lads were also quick, everything was installed in one week as planned,” said Mohammed.

“We plan installations so the level of disruption to the business is kept to a minimum,” said Gordon. “In this case, we were able to install solar panels on the forecourt canopy while still allowing people to carry on using the fuel pumps.”

Each panel is 375W so the total installation is 40kWp, forecast to produce 35,370kWh per year. “The system is due to break even in 3.5 years and from the performance over the past year, we’re certainly on course to achieve this,” commented Mohammed. “Electricity usage in the summer months was £5,000 per month, now it’s £2,500 per month.”

As the premier manufacturer of injection mould plastic parts for medical, water management, electronics and defence markets, the factory at A K Industries has a high energy bill, consuming 1.3MWh of electricity annually.

In 2022, not only was there a lot of volatility in the energy market but material costs also increased dramatically. To stabilise business costs as much as possible, A K Industries decided to investigate what savings were achievable from installing a solar system.

Sam Green, Managing Director at the company, sought the advice of Solarkinetics to specify a solar system with the solar panels fitted to the factory’s roof and determine the resulting pay-back time.

With a pay-back forecast to be just 2 and a half years, it was easy to justify installing a solar system that will be producing power for many decades. In fact, the solar panels came with a 25 year warranty on workmanship, defects and linear performance output

In 2023, a solar installation of 1280 x 375Wp REC Twin Peak 4 were installed along with three inverters: 2 x Solaredge 100kW Synergy Manager and 1 x Solaredge 50kW Synergy Manager.

“A K Industries is a family business as is Solarkinetics and this was a huge attraction,” said Sam.  “In business I find that the fundamental foundation for an effective working relationship is trust and confidence with those you work with – this I found with Gordon and Jaine, owners of Solarkinetics. Their customer focused approach was just what we wanted.”

The District Network Operator (DNO) limited export to 11kWh so at the weekend when the factory is closed not all the power generated is exported. Even so, the solar system is forecast to save £95K in 2023.

“Despite the solar system being large and taking three weeks to install, the team did an excellent job, without causing disruption to the business.

For A K Industries, the main driver was combating rising electricity costs, with the added benefit of supporting our sustainability targets,” added Sam.
