You don’t need a south-facing roof for solar ☀️

That rule dates back 10 to 15 years, and panels have come a long way since.

East and west roofs give you two roofs to fill, so you can fit more panels and get more generation overall. North-facing roofs still work too, just less efficiently.

Not sure what your roof can do? Send us a photo and we’ll tell you 🙌

A standard solar and battery system won’t keep your lights on in a power cut 🔌

Without the right kit, it would push power back down the grid while engineers are working on it. So it shuts off.

Add a gateway, like the Sigenergy one here, and your home drops into island mode the moment the grid goes. You get a notification in the app, run off your battery, and it reconnects by itself once the grid is stable again.

Want to know if it’s worth it for you? DM us 😅

If you’re getting solar or a battery fitted, that’s the time to upgrade your consumer unit💡

Done as part of the package, it goes in at 0% VAT. That’s 20% off something a lot of homes need doing anyway.

On this job it wasn’t optional. The gateway lets the house run off grid, so every circuit needed RCD protection first.

DM us and we’ll take a look at yours 🤝

Surrey install, finished last week ☀️

24 DMEGC 470W panels, 14 on the front and 10 on the back, fitted on Van der Valk on-roof mounting. That’s 11.28kWp up there.

Round the back it’s Sigenergy again. 8kW inverter, two 9kWh battery modules and the full home backup gateway, so the house keeps running through a power cut 🔋 Earth rod’s in the front garden to give it its own reference.

This one runs two air con units and the bills showed it. When a house uses that much, a bigger system is the one that makes sense. Big outlay, but it’ll be working hard from day one.

🏠 Solar, battery, EV charger and heat pump — all talking to each other.

SolarEdge east-west array with an optimiser on every single panel, so we can monitor and maintain each one individually.

Then the myenergi ecosystem: Libbi battery, Zappi EV charger, and an eddi on the hot water cylinder ⚡

Plus DC surge protection on both strings, a new consumer unit, gen meter, and every device hardwired into a network switch — no Wi-Fi dropouts, ever.

⚡ 8kW of panels. 9kWh of storage. Full home backup.

East-west split roof, 16 x 500W bifacial panels feeding a Sigenergy 6kW inverter and 9kWh battery 🔋

Plus a 100A backup gateway with a TT rod for earthing, and an upgraded consumer unit as part of the works ✅

All tucked under the front doorsteps — tight, but exactly where it needed to go 🔧

8 panels. 2 strings. 8 optimisers. Zero compromises 🔧⚡

Wall-mount and pitched roof on the same string shouldn’t work — Tigo optimisers say otherwise 👀

No roof space? No problem 🏠

This Hove terrace could only fit 6 panels up top — so we wall-mounted 2 more. 3.5kW total, and the wall panels are performing way better than most people expect ⚡☀️
