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 and home energy solutions available — designed specifically for homeowners who want to reduce costs, cut carbon, and enjoy greater energy independence.
From solar panels and battery storage to heat pumps and EV chargers, we bring cutting-edge technologies to homes across the Channel Islands — carefully selected for their performance, reliability, and sustainability.
Air Source Heat Pumps
Modern air source heat pumps are a smart, low-carbon retrofit solution for homeowners looking to reduce energy costs and emissions. At Little Green, we specialise in integrating efficient, renewable heating into existing properties across Guernsey – with minimal disruption and long-term savings.
Designed for retrofits: Our systems work seamlessly with your 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 warmth and hot water, using ambient air and electricity — reducing your carbon footprint and energy bills.
Ready for renewables: Combine with solar PV or battery storage to future-proof your energy system and unlock even greater efficiency.
Battery Storage
Take control of your home’s energy use and stay powered during outages with our smart battery storage solutions. Designed to work alongside solar panels or 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 household habits and optimise storage to reduce bills.
Stay powered during outages: Instant backup ensures your home 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 unique to the Channel Islands.
Best for compact spaces: 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.
Flexible and future-proof: While ASHPs offer higher efficiency, electric boilers can still reduce 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 we move — reducing emissions, improving air quality, and supporting Guernsey’s 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 your home: 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 home renovation or energy upgrade, 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 perfectly with solar panels, heat pumps, and electric heating systems.
Solar PV
Photovoltaic (PV) panels are at the heart 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 homeowners the most reliable and long-lasting panels on the market.
Keep your footprint green: Solar panels ensure your home generates clean, renewable electricity — cutting both emissions and bills.
Power your home, your way: Generate your own power, reduce reliance on the grid, and make an investment that pays for itself — often increasing your home’s resale value too.
Built to last: Our experienced installation teams are experts in delivering high-quality, bespoke solar systems tailored to each property.
Wind Turbines
Take advantage of Guernsey’s coastal climate with a vertical wind turbine. Generating your own electricity through the power of the air is a simple and sustainable way to reduce bills and your carbon footprint. Little Green maintains a strong partnership with AirTurb, giving homeowners access to the latest wind energy technology.
Perfect for a blustery Bailiwick: With consistent winds throughout the year, local homes can benefit from reliable wind-generated power.
A truly renewable resource: Enjoy entirely sustainable energy, generated by one of the Earth’s most abundant resources — wind.
Quiet, flexible, and efficient: The AirTurb Model One sits on any flat surface and is vibration-free, silent, animal-friendly, and fully recyclable.
