Why choose GGRS
40 Years of Group Experience
Renewable energy specialists, supported by the Kelly Group. GGRS became part of the Kelly Group in 2025, combining specialist renewable energy services with the national infrastructure of a group founded in 1985.
Rapid Installation
GGRS delivers a proficient, competent and uninterrupted start to finish installation. We provide bespoke technical quotes and once on-site, our efficient teams typically complete a standard residential solar PV installation in just two days subject to system design and building configuration.
UK-Based
With over 40 operational hubs across the UK, we draw on nationwide experience. Our microgeneration certification scheme (MSC) and the National Association of Professional Inspectors and Testers (NAPIT)-accredited teams manage key stages of delivery. From central design to local delivery, we work to recognised UK engineering standards to deliver compliant system installations.
High-efficiency, Solar technology
We install high-performance, solar PV technology designed to deliver strong yields in a range of UK weather conditions including lower light levels. These professional-grade modules are the same panels used in one of our 3.5MW industrial projects and come with 25-year warranties, subject to product and installation terms.
In-house installation teams
Unlike many providers who outsource elements of delivery, we use in-house teams for key stages of installation. This supports clear accountability and consistency across projects, to provide a seamless experience from initial design through to final commissioning and live connection of your property.
Complete Lifecycle Support
we offer ongoing maintenance and diagnostics services to support system performance over time. Our team executes a high volume of annual service visits and provides responsive support services to help minimise downtime. Regular maintenance can help maintain system efficiency though out its operational life.
Start Reducing Energy Bills
Start saving with a system designed to reduce household bills. By pairing solar with a battery, you can significantly increase electricity self-consumption.
PV, Battery & EV Full Solutions
We deliver a closed loop energy system by integrating high output solar PV with smart battery storage and EV charging. This solution may significantly reduce grid dependence depending upon system size, energy usage, and site conditions.

What our clients say about our services
Your Savings With GGRS
Take total control of your energy costs by powering your life with solar-generated power.
Calculating your potential savings involves balancing your current grid usage against a high-output GGRS system and smart battery storage.
Based on our installation data, here is a breakdown of the long-term financial benefits you can expect based on your property size.
*Figures are based on illustrative UK national averages. See our full Calculation Assumptions & Disclaimers below.
Should I Include a Battery System?
It’s the most common question we get. While every home is different, adding storage is almost always the smarter long-term move.
Think of solar panels as the “engine” and the battery as the “fuel tank”. One creates the power, the other ensures you can actually use it when you need it most.
If you decide to go the storage route, we’ll help you find the perfect battery capacity to maximize your daily savings and ensure your system pays for itself as quickly as possible.
Solar without a battery
Immediate generation - Solar PV systems begin generating electricity as soon as they are installed and exposed to sun light, helping reduce reliance on grid electricity.
Lower Entry Cost - A solar-only system typically requires a lower initial investment compared to systems with battery storage.
Bill Savings - Depending on system size, house hold energy usage and electricity tariffs, solar PV can reduce annual electricity bills. Savings will vary subject to consumption patterns and export rates.
Export Earnings - Excess electricity exported to the grid may be eligible for payments under schemes such as the Smart Export Guarantee (SEG)
Future Flexibility - Battery storage can often be added later, allowing systems to be expanded overtime where compatible.
Solar with a battery
Increased energy independence - Battery storage allows you to store excess solar energy for use during the evening and periods of low sunlight, helping reduce reliance on the grid.
Reduce your electricity costs by minimising your grid reliance
Blackout Support - Many of our battery systems provide an Emergency Power Supply (EPS) during grid outages.
Long term value potential - While the initial cost is higher, the significantly larger monthly savings typically result in a better long-term savings.
