How do Octopus solar panels compare with a local installer?

Here's a like-for-like view for a Greater Manchester home:

The local figure uses the MCS benchmark of £1,565–£1,785 per kWp for 5.46kWp, plus £5,500–£7,000 for a 10kWh battery. Real local quotes vary, so get one to compare. Our solar panel cost guide has a quote checker.

Are Octopus solar panels really cheaper?

On the headline package, yes. £11,115 is well below what the benchmark suggests for a similar local system, largely because Octopus buys kit and installs at scale.

But compare like for like. Check the battery's usable capacity, the inverter type (a string inverter and microinverters aren't equivalent on a shaded roof), what warranties cover, and whether your roof is even eligible. A local installer may match the price once you ask for the same kit.

Which export tariff pays most for solar in 2026?

The top rates are mostly tied to buying electricity from the same supplier. Sunsave's September 2026 table puts Good Energy at 25p/kWh fixed, EDF Export Exclusive at 18p variable and E.ON Next Export Premium at 17.5p fixed, all for their own customers. Ecotricity's 16p variable is open to all.

Octopus pays 12p/kWh on Outgoing Octopus, and 4.1p on its SEG tariff, which you can combine with any supplier. Octopus Flux pays up to 29.32p/kWh at the 4pm–7pm peak if you have a battery. Model each rate in the solar payback calculator.

When should you choose a local installer?

When your roof is awkward, you want specific kit, or you'd rather deal with someone local after installation. East–west terraced roofs, dormers, heavy shading and flat roofs often need a custom design. See how roof orientation affects yield on our Manchester solar page.

Local installers also know council schemes and group-buy rounds. If you might qualify for funding, check our Greater Manchester solar grants guide first. Adding storage later? Read the solar battery guide.

When does a national brand make sense?

When your roof is simple, you're happy with the standard kit, and you'll stay on the same supplier's tariffs. The package is straightforward and the headline price is competitive.

Either way, get at least two quotes and compare the price per kWp. Use our borough comparison to see what your roof should generate, and request a local quote to set against a national one.

Methodology

Octopus prices come from Octopus's own help page (July 2026 pricing), and kit and exclusions from ExpertSure's July 2026 review. The local comparison applies MCS benchmark prices (£1,565–£1,785 per kWp) to 12 × 455W panels (5.46kWp), plus Heatable's 10kWh battery range. Export rates come from Octopus and Sunsave's table dated 16 September 2026. We aren't paid by any supplier named here.
