Do solar panel installations in Horsham require planning permission?

In most cases, no. Solar panels on domestic properties in Horsham fall under permitted development rights, meaning no planning application is required. Exceptions include listed buildings and properties within certain conservation areas — in those cases, you would need to apply to Horsham District Council. Our team will confirm your permitted development status during the site survey.

How close are Electrotec to Horsham?

Our main office is in Crawley, West Sussex — approximately 13 miles from Horsham town centre. We carry out installations across the whole of the Horsham District, including Horsham town, Southwater, Billingshurst, Henfield, Broadbridge Heath, Warnham, Slinfold, Barns Green, Partridge Green and Rudgwick.

What's the typical timeframe for a solar installation in Horsham?

For a standard residential solar installation, the physical installation is typically completed in one to two days. Scaffolding is erected the day before and collected shortly after. From the point of accepting your quote, the average time to installation is four to six weeks, depending on availability and scaffolding scheduling.

How do I know if my Horsham property is suitable for solar?

Most properties in the Horsham area are well-suited to solar. Ideally your roof should face south, southeast, or southwest with minimal shading. We can also install on east/west split roofs or ground-mounted arrays where a suitable roof is unavailable. Our surveyor will assess your specific roof and give you an honest assessment before any commitment is made.

What solar panel packages do you offer in Horsham?

We offer three main packages: a 4kW solar-only Bronze Package (9 panels) from £4,999; a 5kW solar with 5.76kWh FoxESS battery Silver Package (11 panels) from £7,999; and a 6kW solar with 11.52kWh FoxESS battery Gold Package (13 panels) from £9,999. All include scaffolding, bird protection, a 25-year warranty, and free monitoring app. Finance is available on all packages.

Can I add battery storage later if I start with solar only?

Yes. We can return to retrofit a compatible battery storage system after your solar panels are installed. However, installing battery storage at the same time as your solar panels is generally more cost-effective and avoids a second scaffolding visit.

What happens to surplus solar energy I don't use?

Any electricity you generate but don't use can be exported to the National Grid through the Smart Export Guarantee (SEG). Your energy supplier pays you a per-unit rate for this exported energy. Adding a battery means you store and use more of your own generation rather than exporting it at a low rate — which typically improves your overall return on investment.

Do you install solar panels in Crawley?

Yes. Electrotec Power Solutions is based in Crawley at Manor Royal and is one of the most experienced MCS-certified solar panel installers in Crawley and the surrounding areas of West Sussex and Surrey. We offer free site surveys and same-day quotes.

Are you MCS certified for solar panel installation?

Yes. Electrotec Power Solutions Ltd is MCS certified, which is the industry standard required for all solar panel, battery storage and heat pump installations in the UK. Our MCS certification also means customers can access government incentives including the Smart Export Guarantee (SEG).

Do you install battery storage in Sussex and Surrey?

Yes. We install FoxESS and Tesla Powerwall battery storage systems across Sussex, Surrey and South London. Battery storage can be installed alongside new solar panels or added to an existing solar system.

Are you a Warm Homes Plan approved contractor?

Yes. Electrotec is PAS 2030 accredited which is the required certification for all works delivered under the Warm Homes Plan, including the Social Housing Fund and Warm Homes Local Grant. We work with housing associations, registered providers and local authorities across Sussex and Surrey.

What areas do you cover for solar panel installation?

Electrotec Power Solutions installs solar panels across West Sussex, East Sussex and Surrey including Crawley, Horsham, Haywards Heath, Reigate, Redhill, Dorking, Guildford, Worthing, Brighton, East Grinstead, Gatwick and surrounding areas.

Do you offer EV charger installation?

Yes. We install OZEV-approved EV chargers for both residential and commercial properties across Sussex and Surrey. EV charger installation can be combined with solar panel installation for a discounted package price.

Solar Panels Horsham: Local Knowledge Matters

Did you know? Horsham was founded around 947 AD, and its historic Causeway remains one of the finest medieval streets in the South East — lined with timber-framed houses roofed in locally-quarried Horsham Stone. That heritage still shapes how solar is installed in the town centre today, with conservation considerations that our surveyors are well versed in.

Modern Horsham has grown fast, with developments like Highwood Village, Wickhurst Green and the wider Roffey area, and Horsham District Council has plans for over 16,000 new homes in the years ahead. With nearly 1,920 sunshine hours a year, the district remains one of the best-placed areas in the South East for solar generation, whether your roof sits on a centuries-old cottage or a brand-new estate.

How Does PV Solar Work?

Sunlight Hits the Panels

Your solar panels capture daylight, even on cloudy days, and convert it straight into DC electricity.

Powers Your Home & More

An inverter turns that DC power into usable AC electricity, running your home, charging a battery, and topping up an EV.

Surplus Sent to the Grid

Any energy you don't use is exported safely to the grid under G98 approval or stays stored on-site if you've gone battery-first.

How Much You Could Save

A residential solar system generating 1kWp produces around 850–950kWh a year in the South East.
Adding battery storage means you use more of that energy yourself, instead of exporting it back to the grid.

Residential Solar FAQs

Everything you need to know before switching your home to solar.

What's the difference between the package tiers?

Bronze covers panels only. Silver and Gold add battery storage (FoxESS) so you can use stored energy in the evening. These are a starting point; a free site survey gives you an accurate, tailored proposal.

Will this actually cover my electricity usage, or just offset some of it?

A well-sized system can generate more than you use on a good day, with surplus exported via the Smart Export Guarantee for a payment back. On cloudier days you'll still generate, just less. Most homeowners see a significant reduction in their bills, and adding a battery closes more of that gap.

Is that price the full cost, or are there extras?

The price you receive following your site survey is the complete price. Scaffolding, bird protection, and installation are all included, with no hidden extras.

Will this affect my home insurance or mortgage?

Let your insurer know once installed; most add it to your policy at little or no extra cost. Some mortgage lenders like to be informed too, though it's rarely an issue. We provide the documentation you'll need for either.

Will it work on my roof type, angle, or shading?

Every roof is different. Our free site survey assesses suitability, orientation, and shading so we can size and position your system for the best performance.

Do I need planning permission?

In most cases, no. Solar installations fall under permitted development, with exceptions for listed buildings, conservation areas, and some flat roofs. We'll flag it during your survey if it applies.

What happens if something breaks, who do I call?

Us. Panels carry a 25-year manufacturer's warranty, inverters and battery storage a 10-year manufacturer's warranty, and our installation a 10-year workmanship guarantee.

Can I add a battery or EV charger later if I don't get one now?

Yes, it can be added later, though it's more cost-effective as part of a combined package from the start.
