Everything About Solar
From panels to batteries to EV charging — here's what you need to know before making the switch.
How Solar Panels Work
Solar panels (also called photovoltaic or PV panels) are made up of silicon cells that absorb sunlight and convert it directly into DC electricity. They work even on cloudy days — it's daylight, not direct sunshine, that generates power. A typical UK home installation uses 6–14 panels mounted on the roof, generating electricity throughout the day that can be used immediately, stored in a battery, or exported back to the grid for payment. Modern panels are highly efficient, low-maintenance, and come with warranties of up to 25 years — making them one of the most reliable home energy investments available.
Inverters — The Brain of Your System
An inverter is the essential piece of kit that converts the DC electricity produced by your solar panels into AC electricity — the type used by your home appliances. Without it, your solar panels can't power anything in your house. Modern inverters do much more than convert power: they monitor your system's performance in real time, optimise output across all panels, and connect to apps so you can track exactly how much energy you're generating and using. String inverters are the most common type for residential homes, while microinverters (fitted to each panel individually) maximise output on roofs with shading or complex layouts.
Battery Storage — Power After Dark
Solar panels only generate electricity when the sun is out — but your energy demand doesn't stop at sunset. A home battery storage system captures the excess electricity your panels produce during the day and stores it so you can use it in the evening, overnight, or during cloudy spells. Popular systems like the Tesla Powerwall or GivEnergy range can store anywhere from 5–15 kWh of electricity, which can cover a typical household's evening and overnight needs entirely. When combined with solar, battery storage can dramatically reduce your reliance on the grid — and protect you from peak-rate energy prices. Many customers with batteries export very little and use the majority of what they generate.
Electric Vehicles — Charge for Free
One of the most compelling reasons to go solar in 2025 is the ability to charge your electric vehicle using free energy from your roof. A typical EV requires around 15–20 kWh to charge from near-empty to full — which on a decent solar day, a mid-sized system can provide almost entirely for free. With a smart EV charger that communicates with your solar inverter, charging automatically kicks in when your panels are producing surplus electricity and pauses when demand elsewhere in the home is higher. Over the lifetime of the system, EV owners with solar can save tens of thousands of pounds in fuel and energy costs combined — making the investment case even stronger.
Smart Export Tariff — Get Paid for Surplus
Any electricity your solar panels produce that you don't use — and don't store in a battery — gets exported to the National Grid. Under the Smart Export Guarantee (SEG), energy suppliers are required to pay you for every unit you export. Rates vary by supplier, typically ranging from 4p to 15p per kWh, with some competitive tariffs going higher. While it's always better to use or store what you generate first, the SEG provides a financial return on any genuine surplus and ensures nothing is wasted. Signing up is straightforward through your energy supplier once your system is registered and your smart meter is installed.

Common Questions
Do solar panels work in the UK climate?
Yes — solar panels generate electricity from daylight, not direct sunshine. The UK receives enough light year-round to make solar a sound investment.
How long does installation take?
Most residential installations are completed in 1–2 days with minimal disruption to your home.
What is the payback period?
Typically 6–10 years depending on system size and energy usage, with systems lasting 25+ years.
Do I need planning permission?
In most cases, no. Domestic solar panels are considered permitted development, though we'll confirm this for your property.
