Solar PV &
Battery Storage

A standard 4 kWp roof-mounted array for a Gloucestershire home generally costs around £5,000 – £6,000 fully installed. That figure covers Tier-1 panels, scaffolding, MCS labour and 0 % VAT (in place until 31 March 2027). Precise pricing still depends on roof size, access and optional extras such as EV chargers or battery storage; Hewer FM provides a free survey and fixed quotation before any commitment.

Most households recoup their investment in roughly eight to fourteen years. The range comes from Hewer FM’s monitoring of local installs and assumes typical self-consumption, export payments under the SEG and current energy prices. Adding a battery tends to lengthen pay-back, but it also raises energy independence and cushions future tariff rises.

Yes – the SEG pays you for every surplus kilowatt-hour your system exports to the grid. Rates are set by electricity suppliers and can be flat (e.g. 15 p/kWh) or dynamic. During your survey, Hewer FM will guide you through registration, compare current tariffs and show how to maximise export income.

Absolutely. AC-coupled batteries bolt onto almost any existing array without replacing the inverter, while hybrid solutions can be fitted when an upgrade makes sense. Hewer FM checks wiring capacity, warranties and DNO limits before recommending the simplest route.

Choose a battery with backup functionality and it will switch to powering agreed-upon circuits the moment the grid fails. A small gateway isolates your home from the mains so the battery can run lights, Wi-Fi and refrigeration for several hours, depending on its size. Hewer FM can size the backup load and demonstrate typical run-times at the design stage.

For most properties the installation is classed as Permitted Development. Listed buildings, conservation areas or panels mounted on a roof that fronts a highway may need consent; if that applies, Hewer FM handles the paperwork and liaises with the planning officer for you.

The technology is largely self-monitoring. Hewer FM advises a quick annual visual inspection, plus the occasional panel clean if dust or bird mess builds up. Batteries are sealed units; keeping firmware up to date via their app is usually all they need. Optional service packages are available for added peace of mind.

Yes. PV modules fall under the WEEE scheme, which recovers most of their glass, aluminium and silicon, while lithium-ion batteries are dismantled at specialist facilities to reclaim valuable metals and cathode material. Hewer FM arranges compliant take-back and recycling when the time comes.
