Stop paying for
energy you could
own.
Solar & battery storage, installed properly.
JJB Volta designs and installs premium solar and battery systems that cut what you pay for electricity — in summer, and in winter. Every system is survey-designed, MCS-certified, and backed by a 6-year workmanship guarantee.
Two products. One trusted installer.
Premium equipment, survey-designed systems, and the electrical expertise that solar-only companies cannot match.
Solar & Battery Storage
A premium solar system is more than panels on a roof. The battery is what makes it work year-round — storing what you generate in summer, and charging cheaply overnight in winter. We design both together from day one.
- Trina Vertex N-Type panels — premium efficiency
- Fox ESS hybrid inverter and battery storage
- Time-of-Use tariff optimisation built in
- Full MCS certification and DNO paperwork handled
EV Charger Installation
Home charge point installation by fully approved engineers. We handle the survey, supply, installation and paperwork — with the actual installation typically completed in a single day. Combine with solar and charge your car directly from energy your roof generates.
- Approved EV charge point installer
- Home and workplace installations
- Smart chargers with app control
- Full electrical sign-off and certification
What could solar save you?
Our ROI calculator gives you a personalised payback estimate based on your roof, your usage, and your current tariff — with honest assumptions declared upfront.
The honest twelve-month picture
Most installers present battery storage as a summer benefit. It isn't. A correctly specified system reduces what you pay every single month — regardless of the weather. For a typical JJB Volta installation of 8–10 panels, most homeowners see payback in the 10–14 year range — which, with a 25-year panel warranty, still represents a strong long-term return.
Premium equipment as standard
We specify Trina Vertex N-Type panels and Fox ESS hybrid inverters and battery systems. Not budget components — the systems our engineers would install in their own homes.
A real result from a recent customer
A battery installation we completed in early 2026 doubled the customer's self-consumption and halved their monthly energy bill. They now sell back at 27–37p/kWh during peak hours.
What it adds to your property
UK evidence from Rightmove and RICS points to a 2–3% resale uplift for homes with solar panels. For a home you plan to keep, it's a documented, real-world benefit on top of monthly savings.
Why the electrician matters as much as the equipment
Solar-only companies install panels. JJB Volta are electricians first — which means the system is designed, installed, and certified properly.
MCS & NAPIT Certified
MCS certification is mandatory for eligible SEG export payments. Without it, your system cannot earn money back from the grid. We are fully accredited — and we handle the registration as part of every install.
Fixed Price Promise
We survey, we quote, you agree — that's what you pay. No extras on the invoice, no scope creep. We've built a business on this since 2016.
Workmanship Guarantee
Every installation carries a 6-year workmanship guarantee registered with NAPIT. Equipment comes with manufacturer warranties — 10 years on batteries, 25 years on panels.

“From the initial survey through to switch-on, Jamie explained everything clearly and honestly. The system has performed exactly as he said it would. Bills already noticeably down in month one.
“After getting our first EV, we needed a home charger. Found JJB through Google — outstanding from start to finish. Neat install, done in a day, explained everything clearly. Highly recommended.
