Solar Panels Crawley: Costs, Savings & Grants 2026 System

FoxESS Batteries and KH8 Inverters

Published by Electrotec Power Solutions Ltd | Crawley, West Sussex | Updated April 2026

If you’re a homeowner in Crawley looking at solar panels in 2026, this guide is for you. As a local MCS-certified solar installer based at Manor Royal, Crawley since 2011, Electrotec Power Solutions has helped thousands of West Sussex homeowners make the switch to solar — and we want to give you the honest, practical information you need to make the right decision.

Below we cover what solar panels actually cost in Crawley, how much you can realistically save, what grants and incentives exist right now, and whether battery storage and EV charging are worth adding to your system.


1. How Much Do Solar Panels Cost in Crawley?

Based on MCS-certified installation data for West Sussex, a typical 4.5kWp solar panel system with a 5kWh battery costs around £11,000–£12,500 fully installed in 2026. For larger homes or higher energy usage, systems of 6–10kWp with expanded battery capacity can run from £14,000 to £22,000 depending on specification.

System Type Typical Cost (Installed)
Solar panels only (4–5kWp) £6,500–£8,500
Battery storage retrofit £3,500–£6,000
Combined solar + battery £10,000–£14,000
EV charger added to solar £800–£1,200

All residential solar and battery installations are currently zero-rated for VAT — a significant saving versus most other home improvements, and one that effectively takes 20% off every quote you receive.


2. How Much Could I Save on My Bills?

The average household energy bill in Crawley runs at approximately £2,150 per year. With a properly designed solar and battery system, most homeowners see annual savings of £700–£1,200, with the highest-performing setups — particularly those on a smart tariff like Octopus Intelligent Go — achieving even greater reductions.

West Sussex benefits from some of the highest solar irradiance levels in the UK, meaning Crawley homes generate more usable energy per panel than most of the country. A well-designed 4.5kWp system here typically produces around 4,000–4,500kWh per year.

Typical payback periods for a combined solar and battery system in this area are 6–9 years, after which savings represent a pure return on investment across the remaining 15–25 years of system life.

Smart Export Guarantee (SEG)

Any surplus electricity you generate and don’t use can be sold back to the grid through the Smart Export Guarantee. As an approved Octopus Energy partner, Electrotec can help you access Octopus Flux — one of the most competitive export tariffs currently available — potentially earning you an additional £300–£600 per year on top of your bill savings.


3. Grants & Incentives Available in 2026

Warm Homes: Social Housing Fund

In 2025, Crawley Borough Council received £5.7 million in Warm Homes: Social Housing Fund government funding. This scheme supports solar PV, insulation and heating upgrades for social housing tenants. If you’re in council or housing association accommodation, contact Crawley Borough Council directly to check whether your property is included.

0% VAT on Solar and Batteries

This applies to all private homeowners. All residential solar panel and battery storage installations currently attract 0% VAT, whether you’re installing a brand new system or adding a battery to existing panels.

Smart Export Guarantee (SEG)

Once your MCS-certified solar system is installed, you’re legally entitled to be paid for electricity you export to the grid. Electrotec can advise which provider offers the best rate for your setup.

Green Finance Options

For homeowners who want to spread the cost, Electrotec can arrange 0% green loan options depending on your mortgage provider, as well as flexible finance through our approved credit partner. Many customers find that monthly repayments are offset — or even exceeded — by their energy savings from day one.


4. Is Battery Storage Worth It in Crawley?

For most Crawley homeowners, the answer is yes — and the numbers back it up.

Without battery storage, solar panels only benefit you when the sun is generating more than you’re consuming — typically between 9am and 4pm. Any surplus is exported to the grid at a relatively low rate, while you still pay full price for electricity in the evenings.

With a battery system, that surplus is stored and used overnight, replacing expensive peak-rate grid power with your own free solar electricity. In a typical household, battery storage can double your self-consumption rate from around 30–35% up to 70–80%, dramatically improving both your annual savings and your payback timeline.

Our most popular battery system for Crawley homes is the FoxESS EP series — available from 10.4kWh, scalable up to 41.6kWh, with a 10-year warranty, IP65 rating and full app monitoring. We also install Tesla Powerwall for homeowners who prefer the Tesla ecosystem.


5. What About EV Charging in Crawley?

Crawley is seeing strong growth in EV ownership, particularly across newer developments such as Gatwick Green and Forge Wood. If you drive an electric vehicle — or plan to switch — combining an EV charger with solar and battery storage creates the most cost-effective home energy setup available.

With an integrated solar, battery and EV charging system you can:

  • Charge your vehicle primarily on free solar-generated electricity during daylight hours
  • Draw from stored battery power for overnight top-ups
  • Benefit from smart tariffs like Octopus Intelligent Go, which can bring overnight charging costs down to as little as 7p/kWh

As an approved Octopus Energy partner, Electrotec handles the full setup — charger installation, tariff registration and system integration — so everything works together from day one.

7. Common Questions from Crawley Homeowners

Do solar panels work in cloudy weather?

Yes. Solar panels generate electricity from daylight, not direct sunshine. West Sussex consistently delivers enough annual solar irradiance to make solar panels a strong financial investment — battery storage means you capture and use every kilowatt generated, even on overcast days.

How long does a solar installation take in Crawley?

A standard residential solar and battery installation is typically completed in one to two days, including scaffolding, panel fitting, inverter and battery installation, monitoring setup and full sign-off.

Will solar panels add value to my home?

Yes. Research consistently shows that homes with solar panels command a premium over comparable properties. With energy costs remaining elevated and buyer awareness increasing, a certified solar installation is increasingly valued by estate agents and buyers across West Sussex.

I already have solar panels — can I still benefit?

Absolutely. We offer battery retrofits and system upgrades for existing solar installations, including customers still on the old Feed-In Tariff (FIT). If your inverter is ageing or your system is underperforming, we can assess whether an upgrade would improve generation and savings.

Can I get a quote without committing?

Yes. We offer a free, no-obligation solar assessment — at your home or virtually — with a full written specification and costings provided. No pressure, no hard sell.
