Solar panels in Kent: frequently asked questions

How much electricity can solar panels generate in Kent?

Kent is among the sunniest regions in the UK, falling within MCS irradiance Zone 2 (Brighton/SE England) for much of the county. A typical 4 kWp south-facing system at 35° pitch can generate around 4,400–4,600 kWh per year in Kent, which is enough to meet a significant portion of an average household's annual electricity demand of approximately 3,500 kWh. Use the calculator above with your postcode for a precise figure based on your location, roof orientation and pitch.

Is my home in Kent suitable for solar panels?

Most homes in Kent are well-suited to solar PV. The key factors are a south, south-east or south-west facing roof with a pitch between 20° and 50°, minimal shading from trees or neighbouring buildings, and adequate roof space (a 4 kWp system typically requires around 20–25 m²). Our calculator accounts for all of these factors. An MCS-certified installer such as Convert Energy can carry out a full site survey to confirm suitability.

How much do solar panels cost in Kent?

A typical domestic solar PV installation in Kent ranges from approximately £5,000–£9,000 for a 4–6 kWp system, depending on panel specification, roof type and complexity of the installation. Adding battery storage typically adds £3,000–£8,000 depending on capacity. Convert Energy provides free no-obligation quotes. Use the calculator above and click "Discuss your project" to get in touch.

What is the Smart Export Guarantee (SEG) and how much can I earn?

The Smart Export Guarantee requires licensed electricity suppliers to pay households for surplus solar electricity exported back to the grid. SEG rates typically range from 4p to 15p per kWh depending on your supplier and tariff. Some time-of-use tariffs offer significantly higher rates during peak periods. The calculator defaults to 12p/kWh but you can override this with your actual SEG rate for a more accurate estimate.

What does MCS certified mean for solar installers?

MCS (Microgeneration Certification Scheme) is the UK's quality mark for small-scale renewable energy. MCS-certified installers must design and install systems to the standards set out in MIS 3002:2025, use MCS-listed products, and issue an MCS Installation Certificate on completion. This certificate is required to access the Smart Export Guarantee and certain other incentives. Convert Energy is an MCS-certified solar installer operating across Kent and the South East.

Should I add battery storage to my solar panels?

Battery storage allows you to use solar electricity generated during the day in the evening, increasing your self-consumption and reducing grid imports. It is particularly beneficial if you are out during the day. Our calculator models battery performance using the official MGD 003 lookup tables. Toggle battery storage on in Step 4 to compare your estimated savings with and without a battery.
