Solar, battery & EV

Solar, storage and charging asone system.

Panels, a battery and an EV charger sized around how your home actually uses energy, so you store and use more of what you make.

Why this matters

Rising unit rates and the question: will solar actually pay back?

Solar, battery, and EV charging make sense designed together. But savings depend on roof, shading, occupancy, whether you add a battery, and your tariff. Without proper modelling, you end up generating power at the wrong time of day.

What you get

Generation you understand, storage when it earns its place, and charging that works with both

Solar, battery and EV charging designed as one system, so each part earns its place before it goes on your roof.

Our approach

One designer, one install, one set of documentation

01 / 04
Solar PV, Battery Storage & EV Chargers — Shade-aware panel layout
01

Shade-aware panel layout

We use actual site photography, roof-pitch data, and annual shade modelling to place panels where they produce, not just where they fit.

Solar PV, Battery Storage & EV Chargers — Battery sized on payback, not headline kWh
02

Battery sized on payback, not headline kWh

A 10 kWh battery is not always better than a 5 kWh battery. We model your evening load profile and size for payback in your real circumstances.

Solar PV, Battery Storage & EV Chargers — EV charger integrated with solar export
03

EV charger integrated with solar export

Solar-aware chargers (Zappi, Indra, etc.) that prioritise charging from your own generation before pulling from the grid. Configured, tested, and demonstrated at handover.

Solar PV, Battery Storage & EV Chargers — MCS and DNO handled end-to-end

MCS and DNO handled end-to-end

G99 or G98 application to your DNO, MCS install certificate, TrustMark lodgement, and HIES or RECC consumer code protection, all handled by us.

The process

How it works

No surprises, no jargon. A clear, documented path from your first call through to handover and the follow-up visit, so you always know what happens next and why.

Solar PV, Battery Storage & EV Chargers — step 1: Feasibility conversation
01

Feasibility conversation

Fifteen minutes on the phone. Roof orientation, annual electricity usage, EV plans, any existing solar. We tell you honestly what a good system might look like before booking a survey.

Solar PV, Battery Storage & EV Chargers — step 2: Desktop and on-site survey
02

Desktop and on-site survey

Satellite imagery and shade modelling first, then a site visit for roof structure, electrical supply, consumer unit condition, and cable routing. Approximately ninety minutes on site.

Solar PV, Battery Storage & EV Chargers — step 3: Design and fixed quote
03

Design and fixed quote

Panel layout diagram, inverter specification, battery model (if recommended), EV charger specification, conservative annual generation estimate, and a fixed price broken down by component.

Solar PV, Battery Storage & EV Chargers — step 4: Installation
04

Installation

Typically one day on the roof, one day on the electrical install. Panels, inverter, battery, EV charger, consumer unit work, and meter commissioning, all completed in a single visit.

Solar PV, Battery Storage & EV Chargers — step 5: Monitoring walk-through
05

Monitoring walk-through

Before we leave, we install the monitoring app on your phone, show you what good looks like, and explain when to expect peak generation. MCS certificate emailed within two working days.

Our signature honesty

Where we won’t fit it

The roof is mostly north-facing, or heavily shaded by trees or buildings. Even the best panels produce a fraction of their rated output on a bad roof orientation. We use drone photogrammetry to measure actual solar exposure. We won’t fit panels where the maths doesn’t support them.

You use very little electricity during the day and don’t want a battery. With no battery, solar only saves you money while you’re actively using it. Households that are out all day and don’t charge an EV or run a heat pump see poor payback without storage.

You’re planning to move within 5 years. Solar adds some resale value but not usually enough to recoup the install cost in a short window.

Your roof needs replacing in the next 5 years. Better to do the roof work first. Otherwise we’d have to remove and refit the panels at additional cost.

We’d always rather show you the honest numbers than install panels that’ll disappoint you.

Honest generation estimates

We quote conservative annual generation figures based on MCS standards, typically 10–15% below the best-case figures some installers quote.

Battery sized for you, not for the brochure

We recommend a battery only when payback is under ten years. If the numbers do not stack up, we say so.

Straight answers

Frequently asked questions

06 questions · asked on real surveys

Q01How much will solar actually save me?

Savings depend on your annual electricity usage, when you use it, your roof orientation, whether you add a battery, and your export tariff. A typical 4 kW system on a south-facing roof in the South of England generates 3,600–4,000 kWh per year. If you can self-consume 40% of that and export the rest on SEG at ~15p/kWh, annual savings are roughly £750–£900. With a battery, self-consumption can rise to 70–80% and savings proportionally increase.

Q02Do I need a battery?

Not always. Batteries make sense if your evening usage is high (heat pump, EV charging, work from home) or if you are on a time-of-use tariff that benefits from overnight off-peak charging. If you are out during the day and home only briefly in the evening, a battery may not pay back before the warranty expires. We model this honestly.

Q03Can I get solar on a north-facing roof?

Yes, but output drops by roughly 30% compared to south-facing. East-west split is often better than north alone. We use actual annual generation modelling, not rules of thumb, to tell you whether a given roof is worth installing on.

Q04What about the MCS certificate and SEG tariff?

An MCS install certificate is required by all major Smart Export Guarantee (SEG) tariffs. We are MCS certified, so you receive the certificate automatically. Your DNO application (G98 or G99) is also handled by us before the install.

Q05Does the install damage the roof?

Correctly installed solar is neutral or slightly positive for roof longevity (UV protection). We use proper flashing, seal every penetration, and photograph each fixing. If we find your roof is in poor condition during survey, we say so before quoting, because reroofing a few years after a solar install is expensive and frustrating.

Q06Can you install an EV charger on its own?

Yes. We install OLEV-approved chargers (Zappi, Andersen, Ohme, Indra) with or without solar. Typical install is half a day. We handle the DNO notification.
