SERVICES
Leading innovators,
big impact
Little Green delights in its partnerships with world-leading innovators like AirTurb, Maxeon SunPower, SigEnergy, SolarEdge and more.
We provide the most reliable and innovative solar PV solutions on the market, catering to residential, commercial, and public sector clients.
We also provide world-leading products in the battery storage, wind turbine, and electric vehicle charging fields. Little Green is always on the lookout for new innovations to bring to the Channel Islands, just as we did with large-scale PV solutions.
Air Source Heat Pumps
Modern air source heat pumps are a smart retrofit solution for homes and businesses looking to reduce energy costs and emissions. At Little Green, we specialise in integrating low-carbon heating into existing properties across Guernsey – with minimal disruption and long-term savings.
Designed for retrofits: Our systems work with existing radiators or underfloor heating, replacing oil or gas boilers without the need for major building changes.
Smarter, cleaner heating: Air source heat pumps deliver reliable heating and hot water, using ambient air and electricity – reducing your carbon footprint and energy bills.
Ready for renewables: Integrate with solar PV or battery storage to future-proof your energy system and unlock even greater efficiency.
Battery Storage
Take control of your energy use and stay powered during outages with our smart battery storage solutions. Designed to work alongside solar and off-peak tariffs, our systems maximise savings and minimise disruption — giving you energy independence and peace of mind.
Smarter energy management: Our intelligent systems learn your usage habits and optimise storage to reduce bills.
Stay powered during outages: Instant backup ensures your home or business remains connected when the grid goes down.
Prepared for any forecast: Weather-aware features charge your system in advance of storms or supply issues.
Electric Boilers
High-efficiency electric boilers offer a practical, low-carbon upgrade for homes where air source heat pumps may not be the best fit. At Little Green, we help you choose the right heating solution – balancing performance, cost, and property constraints for the Channel Islands.
Best for compact spaces: Electric boilers are ideal for smaller homes, flats, or properties without outdoor space – requiring no external unit, flue, or planning considerations.
Low-hassle installation: Easier to retrofit than ASHPs in certain cases, electric boilers connect directly to your existing pipework and radiators, with minimal disruption or changes.
Flexible and future-proof: While ASHPs offer higher efficiency, electric boilers can still cut carbon and running costs – especially when paired with solar panels, battery storage, or time-of-use tariffs.
EV Charging
The shift to electric vehicles is transforming how Guernsey moves — reducing emissions, improving air quality, and supporting our journey towards net zero by 2050. Little Green offers a wide range of smart EV chargers tailored to your vehicle, energy setup, and lifestyle.
Smart, efficient charging: Our EV chargers deliver rapid, reliable charging for all vehicle types, with options to schedule charging around off-peak rates for maximum savings.
Solar synergy: Pair your charger with solar panels or other renewables to power your journeys using clean, self-generated energy — making every mile more sustainable.
Tailored for you: From single-home installs to multi-vehicle workplace setups, we provide expert advice, compatible hardware, and ongoing support across the Channel Islands.
Mechanical Ventilation & Heat Recovery (MVHR)
As part of a whole-house renovation, MVHR systems offer a highly effective way to improve indoor air quality, reduce heat loss, and boost overall efficiency. Whether you're upgrading insulation, replacing windows, or switching to low-carbon heating, MVHR completes the picture for a healthier, future-proofed home.
Clean, fresh air – all day, every day: MVHR extracts stale air and delivers filtered fresh air throughout your home – reducing condensation, mould, and indoor pollutants, even in older properties.
Better performance from your insulation: Airtight homes hold on to heat – but without proper ventilation, that heat (and air quality) suffers. MVHR recovers warmth from outgoing air and uses it to temper incoming air, improving comfort without increasing energy bills.
Ideal for energy-conscious renovations: Quiet, discreet, and highly efficient, MVHR integrates beautifully into renovated homes, and pairs well with solar panels, heat pumps, and electric heating systems for maximum energy savings.
Solar PV
Photovoltaic (PV) panels are the bread and butter of Little Green, and we’ve installed over 7,000 of them since 2013. We partner with world-leading PV providers including Maxeon SunPower and SolarEdge to offer our clients the most reliable and long-lasting panels on the market. Our experienced installation teams are experts at what they do, and we always prioritise quality and meeting our clients’ bespoke needs.
Keep your footprint green: Using solar panels ensures your property generates electricity in the most environmentally friendly way possible.
For business or pleasure: Solar PV solutions are perfect for residential properties as well as commercial businesses and community buildings.
Be your own utility: Keep your energy bills down by generating your own power, making an investment into your home that pays for itself and can add significant re-sale value.
Wind Turbines
Take advantage of the windy weather with a vertical wind turbine. Generating your own electricity through the power of the air is an effective and sustainable way to reduce your bills and your carbon footprint. Little Green maintains a strong partnership with AirTurb, giving the Bailiwick access to leading wind turbine technology.
Perfect for a blustery Bailiwick: No matter the time of year, wind levels are often high in the Channel Islands, giving locals access to optimum levels of wind-generated power
An infinitely accessible resource: Enjoy entirely sustainable power, generated by one of the Earth’s most abundant resources: wind. AirTurb products make wind-generated energy accessible to domestic and commercial customers alike.
Flexible and unintrusive: The AirTurb Model One can sit on any flat surface and is vibration free, silent, animal-friendly, and fully recyclable.
