For most UK homes with a south-facing unshaded roof, a string inverter is the most cost-effective choice. If you plan to add battery storage now or later, choose a hybrid inverter — it manages panels, battery, and grid connection in one unit. For roofs with shading, dormer windows, or multiple orientations, microinverters are the better option as they optimise each panel independently. In 2026, the most popular UK brands are Solis, SolarEdge, GivEnergy, Sungrow, and Enphase. See our full solar inverter guide for a detailed comparison.

Solar roof tiles (BIPV) are worth considering if your roof is due for replacement anyway, or if you live in a conservation area where standard solar panels are not permitted. They are 50–150% more expensive than traditional solar panels and typically less efficient (14–20% vs 22–25.5% for N-type panels). However, they are a genuinely elegant solution if aesthetics matter and you’re already budgeting for a new roof. Leading UK-available options include Tesla Solar Roof, Marley SolarTile, and GB-Sol tiles. Expect to pay £20,000–£45,000 for a full roof replacement with integrated solar.

Yes — and it’s one of the most cost-effective things you can do with a solar system. A smart solar EV charger such as the myenergi Zappi detects when your solar panels are generating surplus electricity and automatically diverts it to charge your car for free. Zappi works in three modes: Eco (diverts surplus solar), Eco+ (waits for 100% solar before charging), and Fast (charges from the grid at full speed). A typical 4kW system can supply 60–80% of an average UK driver’s annual mileage in free solar electricity. Read our full solar and EV guide for more detail.

The best solar battery for most UK homes in 2026 is a Lithium Iron Phosphate (LFP) system. Top options include the Tesla Powerwall 3 (13.5kWh, around £8,500 installed), GivEnergy (5.2kWh–13.5kWh, from £3,800), FoxESS ECS series, and Sigenergy. LFP chemistry is safer, degrades more slowly, and lasts longer than older NMC lithium batteries. A typical 5–10kWh battery raises your self-consumption from around 30% to over 70%, and most systems pay back in 9–12 years including bill savings and Smart Export Guarantee income. See our complete battery guide.

An off-grid solar system generates and stores all the electricity a property uses without any connection to the National Grid. It typically consists of solar panels, a large battery bank (often 15–50kWh), a hybrid or off-grid inverter, and frequently a diesel or LPG backup generator for periods of prolonged low sunlight. Off-grid systems are most common in rural UK properties where grid connection costs are prohibitively high (often £20,000–£80,000+). They are viable in the UK but require careful sizing to cope with low winter sun. A full off-grid setup for a UK home typically costs £20,000–£60,000. Check realistic UK solar output figures before sizing your system.

A solar thermal system uses collectors on your roof to capture heat from the sun and transfer it — via a heat exchanger — to your hot water cylinder. Unlike solar PV panels, solar thermal doesn’t generate electricity; it heats water directly. A well-sized system can provide 40–60% of a typical UK household’s annual hot water, rising to 90–100% in summer months. A full installation typically costs £3,000–£5,000 and can save £150–£250 per year on gas bills. Solar thermal works particularly well alongside heat pumps and is eligible for 0% VAT until March 2027.

A solar diverter (also called a solar immersion diverter or solar export diverter) is a device that detects when your solar panels are exporting surplus electricity to the grid and automatically redirects that energy to heat your hot water instead. This effectively turns your immersion heater into a free solar-powered water heater. Without a battery, most homes export 60–70% of their solar generation. A diverter — such as the myenergi Eddi or the iBoost — costs £300–£500 installed and pays back in 1–3 years. It’s the cheapest way to raise self-consumption without buying a full battery system. Compare with battery options in our storage guide.

A solar carport is a purpose-built canopy structure above a parking area that supports solar panels on its roof. It provides covered parking and generates solar electricity simultaneously. In the UK, solar carports are popular for driveways, commercial car parks, and agricultural properties. Domestic solar carports typically cost £8,000–£20,000 and qualify for 0% VAT. They are particularly useful where the main roof is shaded, north-facing, or already at full capacity. Planning permission may be required for larger structures. Consider this option if you’re also looking at flat roof or ground-mount solar.

A solar monitoring system tracks the real-time generation, consumption, and export of your solar setup via sensors and a dedicated app. Good systems — like those from Sigenergy, GivEnergy, or SolarEdge — show you exactly how much energy your panels are producing, how much your household is consuming, how much is going to your battery, and how much is being exported to the grid. Advanced systems use AI to forecast weather, pre-charge batteries from cheap overnight tariffs, and automatically shift household loads to solar hours. Most modern inverters and batteries include monitoring as standard. It’s an essential tool for maximising your solar panel return on investment.
