What we install

All-black solar panels on a slate roof

Solar panels

We size the array from your electricity use and design it around your roof's pitch, orientation and shading. We also handle the NIE Networks paperwork.

  • All-black panels, fitted on the roof or set into it
  • A hybrid inverter that can take a battery later
  • A generation monitoring app on your phone
Typical payback
7–10 years

Home battery storage

A battery keeps the solar you don't use during the day for the evening. On a night-rate tariff it also works without panels, charging cheaply overnight.

  • Lithium iron phosphate (LFP) cells, with a 10-year warranty
  • Power for essential circuits in a power cut, with a backup gateway
  • Charge schedules set up for your tariff
Usable capacity
5–13 kWh

EV chargers

A smart charger on your drive or in your garage, at a fixed price after we survey your supply and cable route.

  • 7.4 kW charger, tethered or socketed
  • Can charge the car from surplus solar
  • Scheduled charging, as the 2021 smart charge point regulations require
Charge speed
About 25–30 miles of range an hour

Generation figures modelled on your roof

Before we visit, we model your roof from satellite imagery and irradiance data for your location. The model covers pitch, orientation and shading from nearby trees and buildings, and we check it at the site survey.

The generation figure on your quote is for your roof and your electricity use, not a UK-wide average.

Part of the B9 group

B9 Renewables is part of the B9 Energy group, from the same Larne base. These photos are from B9 group installs on commercial roofs.

We fit solar, batteries and EV chargers for businesses and farms as well as homes. Commercial and farm solar
