Solar Battery Storage Crawley: Why Add a Battery System?
Solar panels generate electricity when the sun shines — but most households
use the majority of their energy in the morning and evening when generation
is at its lowest. Without a battery, that free daytime electricity gets
exported back to the grid for a fraction of what you paid for it.
A solar battery changes that. It stores the energy your panels produce
during the day and makes it available exactly when you need it — in the
evening, overnight, or during a power cut. The result is less reliance on
the grid, lower electricity bills, and greater energy independence
Looking for battery storage Crawley? regardless of what happens to energy prices in the future.
Battery Storage without Solar Panels
You don’t need solar panels to benefit from battery storage. A standalone
battery system can charge overnight using cheap off-peak electricity —
particularly useful if you’re on an Octopus Energy, Economy 7 or similar
time-of-use tariff — then discharge during peak hours when grid electricity
is most expensive.
For homes on agile or flexible tariffs, a battery system can reduce your
effective electricity cost to as little as a few pence per kWh. Electrotec
installs standalone battery systems across West Sussex and the South East,
fully configured for your tariff and energy usage pattern.
How Much does Battery Storage cost?
Residential battery storage systems installed by Electrotec start from
£2,999 for a single-unit FoxESS installation, fully fitted and commissioned.
The final cost depends on the battery capacity you need, your property’s
existing electrical setup, and whether you’re pairing with a new or existing
solar system.
Tesla Powerwall installations are available from our team and are priced on
application — as a premium product, the Powerwall carries a higher price
point but delivers whole-home backup capability and industry-leading software
integration.
All installations include a full site survey, system design, professional
installation by our in-house team, commissioning, and app setup so you can
monitor your system in real time.
As a FoxESS Elite Installer we stock and install the full FoxESS battery range in Crawley and across Sussex and Surrey. This includes the FoxESS EQ series (EQ4800), EP series, HV2600 and the latest Mira battery system. We also carry out HV2600 to Mira upgrades and EP to EQ upgrades for existing FoxESS customers — a cost-effective way to increase capacity and update your system to the latest technology without replacing your inverter. If you’re searching for a FoxESS battery installer in Crawley, Horsham, Reigate, Guildford or anywhere across Sussex and Surrey, Electrotec should be your first call.
Commercial Battery Storage
Battery storage isn’t just for homeowners. Commercial properties across West
Sussex are increasingly using large-scale battery systems to reduce peak
demand charges, maximise the value of on-site solar generation, and protect
against grid outages.
Electrotec designs and installs commercial battery storage solutions for
businesses of all sizes — from small office units to industrial facilities.
Combined with a commercial solar installation, a battery system can
dramatically reduce your reliance on grid electricity and lock in energy
costs at a predictable fixed rate.

potential savings based on your actual energy consumption data.
