YOUR LOCAL TEAMA family business. Here for the long term.
20+YEARS IN SOLAR EST. 2006
THE PEOPLE BEHIND YOUR POWER
Your local solar experts, since 2006.
When you invest in solar, you want to know who’s fitting it and who you can call afterwards. We’ve spent more than 20 years building a business that North East families can put their trust in.
Stephen and Haley Fairless started Sustainable Energy Engineering in 2006, and the family is still at the heart of the business today. Stephen’s background in electrical engineering and renewable energy helped shape how we work: understand the property, explain the options clearly and install a system we’re proud to put our name to. That approach has taken us from our early installations to more than 2,000 completed projects.
We bought our own Washington premises in 2022 and continue to focus on the North East. Keeping our work local means we can offer the aftercare our customers value. Whether you’re asking about your first solar panel installation, adding a home battery or getting an older system checked, you’ll be speaking to an established team that understands solar and takes your questions seriously.
Our MCS certification, TrustMark registration, RECC membership and Which? Trusted Trader endorsement give you more to go on when choosing an installer. So do our customer reviews and the installations you can see across the region. We want you to feel comfortable with the people, the price and the work before you commit.
Qualified engineers Advice you can understand Local aftercare
Your roof, electricity use and plans for the future all matter. We design and install solar PV, battery storage and EV charging that work together, and explain what each part will do for you.
Start generating electricity from your own roof. We design domestic solar panel installations around your roof space, shading and electricity use, helping you understand how much power you could generate and use at home.
A home battery lets you save spare solar electricity for later, including the evening when the family is home. We install solar and battery systems together and add compatible battery storage to existing solar panels.
Put your business roof to work with commercial solar panels. From local workplaces to schools and community buildings, we plan each installation around the site, its electricity demand and the practicalities of keeping it running.
Considering Tesla Powerwall 3? We’ll talk you through home battery storage, solar integration and backup options, then design an installation around your property and the way you use electricity.
Make charging at home part of the plan. We’ll look at your electrical supply, parking space and daily routine, and explain how a compatible EV charger can work with your solar and battery system.
Solar panels not producing what they used to, or an inverter showing a fault? Our North East solar servicing team can investigate, carry out repairs and advise on upgrades, even if another company fitted your system.
Take a look at the solar panel and battery installations we’ve completed for people and organisations across the North East. Each project shows the equipment we fitted, the size of the system and the finished workmanship.
At this home in Tanfield, we fitted a 9.6 kW solar PV array with a Fox ESS hybrid inverter and 16.4 kWh of battery storage. The panels generate electricity during the day, with the battery providing a way to store surplus power for later. See the full project for the installation details.
Tesla, Sigenergy and Fox ESS give us different ways to meet your needs. We’ll explain the choices in plain English, including battery capacity, where the equipment will go and whether backup power matters to you.
Your home energy, working together.
Tesla Powerwall 3 is one of the home battery systems we install across the North East. It brings solar and stored electricity into one home energy setup, with app-based monitoring to help you see what’s happening. We’ll explain how it fits your electricity use and what additional equipment or arrangements are needed if you want backup during a power cut.
Your electricity needs may change as your household grows or you add an electric car. Sigenergy’s modular storage options are worth discussing if flexibility matters to you. We’ll work out a suitable starting capacity, explain how you control the system and check which future additions would be compatible with the equipment we propose.
We’ve fitted Fox ESS inverters and batteries in homes and commercial properties across the region, including the Tanfield installation above. That practical experience helps us explain the options clearly. We’ll match the inverter and battery capacity to your solar panels, electrical supply and daily usage, and show you how to keep an eye on the system after installation.
We’ll guide you through the decisions without burying you in technical terms. You’ll understand what we’re proposing, why it suits your property and what happens next.
01
Let’s talk
Tell us about your property, your electricity bills and what you’d like to change. We’ll ask a few practical questions and help you decide what is worth exploring.
02
Survey & design
We check the roof, shading and electrical setup before recommending the panels, inverter and battery. Your proposal explains the equipment, cost and estimated solar generation so you can make an informed decision.
03
Install & hand over
Our installers fit and test the system, explain the monitoring and take you through the handover information. We’ll make sure you know how to see what your solar panels and battery are doing.
04
Keep supporting you
If you need advice after installation, you can get back in touch with our local office. We also offer solar maintenance, fault finding, inverter replacement and battery upgrades as your system gets older.
If your organisation uses electricity during the day, it’s worth looking at what your roof could generate. We install commercial solar PV for North East businesses, schools and community buildings, from the initial site assessment through to handover. We’ll look at your demand, available roof space and electrical supply, and explain whether battery storage has a useful role. Our work at Darlington College, Cragside School and local business premises shows the range of projects we can take on.
Solar generation is only part of the picture. Learn how daytime electricity use, battery storage and the way your household runs can affect how much of that power you keep for yourself.
Your electricity tariff matters alongside the equipment. Get to grips with import and export rates, off-peak battery charging and the supplier terms you’ll need to compare before changing a tariff.
An older solar installation may still have plenty to offer. Find out what we check before adding a battery, replacing an inverter or changing the way your existing system works.
These are the questions people often ask when they first call us. If there’s something else on your mind, just ask. You don’t need to understand the technology before speaking to our team.
Yes. Qualifying installations of solar panels and electrical battery storage in residential accommodation currently benefit from 0% VAT until 31 March 2027. This includes eligible standalone battery installations and battery retrofits. The relief applies to qualifying installation work; equipment bought on its own is not covered. We will confirm the VAT treatment in your quotation.
Yes. Solar PV panels generate electricity from daylight, so they can still produce power when it’s cloudy. You don’t need a south-facing roof in every case, either. The direction and pitch of your roof, available space and shade from trees or nearby buildings all affect the design. We assess those details and give you an estimate for your property. You’ll also see how generation is likely to vary through the year, with longer summer days generally producing more than shorter winter days. That gives you a sensible starting point for deciding whether solar suits your home.
How much will a solar and battery system cost?
The most useful price is one based on your property. The number of solar panels, roof access, inverter, battery capacity and any electrical work all make a difference. We’ll look at your electricity use and what you want the system to do, then explain our recommendation in a written quote. You’ll know which equipment is included and why we’ve suggested it. If you’re comparing solar installation quotes, look at the system specification, likely generation and aftercare as well as the total price. We’re happy to talk you through ours so you can make a fair comparison.
Do I need a battery with my solar panels?
No. Solar panels can work without a battery. A battery becomes useful when you want to keep some of the electricity your panels produce for another time, such as cooking dinner or running appliances after sunset. Whether it makes sense for you depends on how much spare solar electricity you have, when you use power and the cost of the storage. We can compare solar-only and solar-plus-battery options using your own household needs. We’ll also explain battery capacity in practical terms, so you can relate the figures to how you use electricity at home.
Can you add a battery to an existing solar installation?
Yes, and you don’t have to be one of our original installation customers to ask. We fit battery storage to suitable existing solar PV systems across the North East. First, we check your inverter, system design, electrical supply and how much electricity you use. That tells us which batteries are compatible and whether other equipment needs to change. If you’re unsure what you have, send us the make and model or a photograph of the equipment. We can explain the next steps and whether a battery retrofit is worth considering for your home.
Will a battery keep my home powered during a power cut?
It can, but only if the equipment and installation are designed to provide backup power. Having a battery does not automatically mean the house will stay on when the grid goes down. Tell us what you’d want to keep running, whether that’s a few essential circuits or a wider part of the home. We’ll explain the available options, any extra equipment and the limits of the proposed setup. How long backup lasts depends on the usable charge in the battery and what you’re powering. We’ll make that clear before you choose a system.
Which areas do you cover?
We work across the North East from our base in Washington. That includes Newcastle, Gateshead, Sunderland, North and South Tyneside, Northumberland, County Durham and Teesside. Our customers include homeowners, local businesses, schools and community organisations looking for solar panels, battery storage, EV charging or solar servicing. You can browse the areas below, or give us a call if you’re unsure whether we cover your address. We’ve deliberately kept our focus on the North East so we can provide the local service and aftercare that matter to our customers.
What happens after my installation?
We test and commission the system, explain how to use the monitoring and provide the relevant handover documents. You’ll be able to see what your solar panels are generating and how your battery is being used, where monitoring is included in your system. If something doesn’t make sense later, contact our team and ask. We also offer solar panel servicing, fault finding, inverter replacement and upgrades, including support for systems fitted by other installers. Your proposal explains the manufacturer warranties and any installation guarantees, so you know what cover applies and who to contact.
What should I have ready for a quote?
A recent electricity bill, your address and an idea of what you’d like to achieve are a good start. Your annual electricity use in kWh helps us size the solar panels and battery sensibly. It’s also useful to know whether you’re usually home during the day, have an electric car or expect your electricity use to change. If you already have solar, tell us the make and size of the system if you know them. You can upload roof or equipment photographs through our enquiry form. Don’t worry if you don’t have everything; we’ll help you fill in the gaps.
