What is Domestic Solar PV and How Does It Work In the UK?

Domestic solar photovoltaic (PV) systems have gained incredible popularity as the UK accelerates toward net zero. Simply put, solar PV panels convert sunlight into electricity, powering your home and helping to lower your energy bills. More and more UK homeowners are turning to solar for its environmental benefits, energy independence, and long-term savings.

A typical domestic system in the UK is around 3.5kWp, outputting roughly 3,000–3,400kWh a year—often up to 50% of a home’s electricity needs depending on usage patterns and array size. The panels produce electricity during daylight, and any surplus can be exported to the grid via the Smart Export Guarantee (SEG) or stored for later use if you have battery storage.

Do I Need Planning Permission or Building Consent For Solar PV on My Home?

Most residential solar PV installations in the UK are classified as “permitted developments,” so you typically do not need planning permission. However, there are exceptions: listed buildings, conservation areas, and communities designated as Areas of Outstanding Natural Beauty (AONBs) may require special consent. It’s always wise to check local council guidelines or consult with an expert like Atlantic Renewables before proceeding.

All solar PV work should comply with building regulations for electrical safety, roofing, and energy performance. Our engineers at Atlantic Renewables manage all regulatory and grid connection paperwork as part of our end-to-end service for a stress-free experience.

How Much Does a Domestic Solar PV System Cost and What is the Payback Period?

As of 2025, the average cost of installing a standard 3.5kWp solar PV system in the UK is around £6,100, varying by region and system complexity. Solar plus battery packages are becoming more affordable, with 5–10kWh battery systems adding £4,000–£8,000 to the total cost but greatly enhancing self-consumption and flexibility.

With typical annual savings of £400–£600 on energy bills and additional Smart Export Guarantee income, the payback period is now between 6–9 years for most homes, dropping further if you optimise use with battery storage. Adding solar increases property value too.

Who Should Install My Solar Panels and Are There Quality or Warranty Requirements?

It’s critical to use an MCS-certified installer for UK solar PV projects—this qualification ensures compliance with performance, installation, and safety standards. Only systems installed by MCS-accredited companies are eligible for the Smart Export Guarantee and manufacturer-backed warranties.

Atlantic Renewables is fully MCS-certified, providing the best-in-class service and long-term support. Beware of non-certified companies or “DIY” attempts: these can void equipment warranties, invalidate SEG eligibility, and pose serious safety risks.

How Do Battery Storage Systems Work With Solar PV?

Solar battery storage lets you store excess solar power generated during the day and use it during the evening or on cloudy days, significantly boosting your self-consumption rates. This reduces imported grid electricity and shields you from price hikes

Battery systems (commonly 5–15kWh for homes) can be installed as part of a new PV system or retrofitted to an existing array—VAT is now 0% on all home battery installations until March 2027.

Some systems allow for time-of-use “smart charging” from the grid at off-peak rates to maximise savings and enable EV charging flexibility.

Thinking about batteries? Our experts at Atlantic Renewables will advise on the optimal battery solution to meet your needs and optimise your solar ROI.

Can I Use My Solar PV System to Charge My Electric Vehicle At Home?

Yes—solar EV integration is one of the fastest-growing trends for UK households. Modern solar-compatible EV chargers optimise charging sessions to use as much surplus solar power as possible, reducing on-grid energy use and charging costs.

To maximise electric vehicle charging with solar, you’ll want a dedicated smart EV charger capable of “solar-only” or hybrid charging modes. Systems like Zappi and Hypervolt allow for this—Atlantic Renewables supplies and installs a full suite of compatible options, ensuring you get the most out of your green investment. For an average daily charge, you’ll need at least 8–12 good-quality solar panels, depending on your EV’s battery size and driving habits.

What Grants or Incentives Are Available for UK Domestic Solar PV Battery and EV Charging?

While direct grants vary year-to-year, the government’s Smart Export Guarantee (SEG) pays households for exporting unused solar electricity to the grid (variable rates—check with your supplier).

There is a 0% VAT rate for both new and retrofit domestic battery storage through March 2027, making battery upgrades especially attractive. The EV Chargepoint Grant may support flat and rented property residents with installation of a home charger; ask our team for up-to-date eligibility and advice.

How Do I Maintain My Solar PV Battery and EV System For Long-term Performance?

Solar PV panels are designed for low maintenance: an occasional clean and annual inspection by a professional are usually enough. Inverter and battery monitoring are often included via smart apps, allowing you to spot any faults or performance dips.

All our Atlantic Renewables systems are covered by robust warranties (typically 25 years for panels), with ongoing support available from our engineers..
