Solar & battery installation in Harpenden
Harpenden's substantial Edwardian and interwar family homes pair big roofs with big electricity bills — the exact combination where a properly sized solar and battery system repays fastest. We install across AL5 with a company owner on every job and all paperwork handled.
We work right across Harpenden — from Harpenden Common, Rothamsted Park and the Nickey Line to the surrounding Hertfordshire neighbourhoods.
Postcodes covered: AL5 · Hertfordshire
Local knowledge
What we see on Harpenden roofs.
Roofs & housing in Harpenden
Detached and semi-detached homes around the Commons and towards Kinsbourne Green routinely take 14–20 panel arrays, and their loft space keeps inverter and battery installs tidy. All-black panels are the default spec here — on these streets, appearance matters as much as output.
Planning & permissions
Most of Harpenden proceeds under permitted development, with care needed in the conservation areas around the Commons and the village core. Where a street-facing slope is sensitive, a rear-face design usually recovers the output — we model both before you decide.
Real pricing, custom design
Recent ECONEXIS installs start from £4,990 for solar only, or £6,690 with battery storage — up to around £14,000 for our largest systems. Every Harpenden design is built around your actual roof and usage, and your free custom design is usually back within 24 hours.

Solar in Harpenden — your questions
Who installs solar panels in Harpenden?
ECONEXIS is an MCS-accredited solar panel, battery storage and heat pump installer covering Harpenden and the AL5 postcodes, based in Chadwell Heath, Essex. The company is TrustMark, NAPIT and RECC registered, a company owner attends every installation, and the full job — design, install, DNO grid application and certification — is handled in-house.
How much does solar panel installation cost in Harpenden?
Recent real ECONEXIS installs start from £4,990 for a solar-only system, or £6,690 for a 10-panel system with a 5 kWh battery — up to around £14,000 for a 20-panel system with a large battery. As a guide to sizing: Detached and semi-detached homes around the Commons and towards Kinsbourne Green routinely take 14–20 panel arrays, and their loft space keeps inverter and battery installs tidy, which shapes how many panels fit. Your fixed Harpenden quote is confirmed after a free custom design — usually within 24 hours.
Do you actually cover Harpenden and the AL5 postcodes?
Yes — Harpenden is part of our core install area. We cover AL5 and the surrounding Hertfordshire neighbourhoods, with a company owner on every install. We're also regularly in Wheathampstead and Redbourn, so you'll rarely wait long for a survey slot.
How quickly can you install in Harpenden?
Your free custom design usually comes back within 24 hours. After your survey and go-ahead, most Harpenden installations are booked within a few weeks and completed in one to two days on site.
Do I need planning permission for solar panels in Harpenden?
In short: Most of Harpenden proceeds under permitted development, with care needed in the conservation areas around the Commons and the village core. Where a street-facing slope is sensitive, a rear-face design usually recovers the output — we model both before you decide. We check the rules for your exact address during the free design and handle any paperwork needed — you won't have to deal with the council yourself.
Who handles the DNO application for my Harpenden install?
We do, completely. We prepare and submit the DNO application for your Harpenden property, manage any conditions, and register the system for MCS certification — you don't fill in a single form.
What savings can a Harpenden homeowner expect?
Across our recent quotes, estimated first-year savings ranged from £1,100 to £2,100 with typical payback of 5–8 years, depending on system size and how you use your electricity. Your free design includes savings figures specific to your home in Harpenden — never a generic promise.
