Case Studies
Real installations, real specs, real feedback. Every system here was designed and installed by Matt. No subcontractors, no off-the-shelf packages. Here's what that looks like in practice.
David
4.55 kWp: 10 x Aiko panels, 3.7 kW hybrid inverter, 10 kWh battery
"Matt has just completed and commissioned a 4.55 KWp system consisting of 10 solar panels, a 3.7 KW hybrid invertor and a 10 KWH battery. The work was completed professionally and with minimal disruption by Matt and his "roof man" Gus. Despite the poor weather and short days everything is working well and I am generating and storing energy and saving money already."
Outcome
Generating and storing from day one, even in December. System designed to maximise self-consumption with a 10 kWh battery covering overnight usage.
George
49 kWp commercial PV array + battery storage
"Brilliant service. Friendly. Knowledgeable and very tidy. I would highly recommend. Matt and his team did a 49kw pv and battery system for our business and we are thrilled with the quality of the work."
Outcome
A medium scale commercial install on a wedding venue with battery storage for backup power in case of a grid outage. Battery storage also allows the business to shift load away from peak tariff hours. Significant reduction in energy costs and eligibility for capital allowances.
Holly
Residential solar + battery, panels and batteries fitted around a delicate house build
"Yarmer Renewables did a fantastic job on our house, and made a complex process very straightforward. Matt fitted the panels and batteries quickly and efficiently-- and was mindful of the delicate intricacies of our house build. We're looking forward to much cheaper energy bills!"
Outcome
Required careful integration with an ongoing build. Matt worked around structural constraints and aesthetic requirements. No damage, no fuss. System up and running before the build was complete.
Henry
Solar array relocation and re-commissioning
"Matt managed the re siting of our solar array in an efficient and cost saving way. Always helpful with good advice he went the extra mile coming out on a Sunday to check on the system when I was on holiday. 6 stars to matt and his team."
Outcome
Non-standard job: relocating an existing array to a better position. Matt handled DNO notifications, re-commissioning, and post-install checks, including a Sunday site visit while the customer was away.
Mike
6.5 kWp extension to existing FITs system, Aiko panels, Fox ESS inverter
"Matthew did a great job installing an additional 6.5 kWp of Solar Panels. The job was more complicated because our existing FITs panels competed for grid export capacity and needed priority. Matthew designed and implemented a solution which complied with all the various requirements - FITs, MCS and DNO."
Outcome
Technically complex: had to preserve existing FITs eligibility while adding new capacity. Required careful design to ensure FITs panels retain export priority, new panels are MCS-registered separately, and DNO limits are respected.
Jerry
16 x Aiko panels, hybrid inverter + battery
"Matt from Yarmer Renewables was an accidental contact but it has been a happy accident! Everything has been well designed and is bespoke to this house. The system is in and working perfectly within a month of first contact which is impressive for a 16 panel inverter and battery set up."
Outcome
Full design-to-commission in under a month. 16-panel system with inverter and battery, bespoke to the property. Customer initially hesitant about using a smaller installer, now their strongest advocate.
