Why Go Solar?
Solar PV & Battery Storage Benefits
Slash Energy Bills
Reduce your electricity costs by up to 70%. Most systems pay for themselves within 6–8 years.
Reduce Carbon Footprint
A 4kW system saves roughly 1.5 tonnes of CO₂ per year — the equivalent of planting 60 trees annually.
Increase Property Value
Homes with solar PV sell for an average of 4–14% more. It's an investment that adds real value.
Earn with SEG
Export surplus energy to the grid and get paid through the Smart Export Guarantee and get paid for what you don't use.
Energy Independence
Protect yourself against rising energy prices by generating your own clean power.
25+ Year Lifespan
Modern solar panels last 25–30 years with minimal maintenance. Most come with 25-year performance warranties.

Excellent 4.5/5What Our Customers Say
Excellent service from start to finish
"I wasn't sure exactly what I needed for my solar set up but I was given several options to look at by Nick. After some fine tuning a decision was made and I was booked in much quicker than expected. Matt and Jordan arrived to fit the system — they were both really friendly and very knowledgeable. The installation was fantastic, everything very tidy and I am extremely happy with my panels and battery. The whole team work really well together to provide excellent customer service."
Highly impressed with Helios!
"Highly impressed with Helios! They wired my summer house perfectly! Professional, efficient, and tidy. Great advice throughout, and the job was completed on time. I'd definitely recommend them for any electrical work!"
Prompt, professional and seamless
"Right from the first call with Nick to Matt and Jordan handing off the system they have been a pleasure, and very easy, to work with. The inverter and battery installation was prompt and they explained the whole process before turning off the electricity. We would highly recommend them."
Seamless warehouse installation
"We commissioned Helios for a large warehouse electrical job. The whole process was seamless — they barely intruded on the daily running of warehouse operations and followed clear health and safety protocols throughout. Excellent work from a professional team."
Quick, efficient and friendly
"Couldn't be happier with the service. Had an extractor fan fitted quickly and efficiently. The team were friendly, professional, and left everything spotless. Would definitely use Helios again for any future electrical work."
Fantastic solar installation
