Store for later.
Use a compatible battery to hold solar generation or lower-cost electricity for another time.
Let’s talk INTELLIGENT ENERGY
Solar, batteries and flexible electricity use can work together to lower costs. We help you assess when to store, use or export power around your site’s priorities.
Homes, commercial sites and energy asset owners.
Your tariff, electricity use and equipment.
A clear assessment of the options and commercial terms.
WHAT CHANGES
The value comes from making the right decision at the right time, while respecting the limits of the equipment.
Use a compatible battery to hold solar generation or lower-cost electricity for another time.
Plan discharge around your demand, tariff and chosen battery reserve.
Compare eligible payments with the cost of energy, battery wear and service fees. Market access depends on the agreement.
FROM A DECISION TO A RESULT
A lower purchase price is only part of the calculation. Battery losses, wear, power limits and export terms all affect the outcome.
Our calculator lets you explore a reference scenario. A site proposal uses your actual information and sets out equipment, installation and ongoing costs.

A depot’s vehicles, other electrical loads and battery storage all share the same connection. Planning them together can reveal where time and capacity are available.

No. Some battery use cases depend on tariff timing rather than solar. Eligibility for particular tariffs and programmes still needs checking.
Some eligible assets can participate through suitable market arrangements. Payments, metering, availability commitments and fees must be confirmed for the service.
The proposal should state the permitted controls, your operating priorities, monitoring and what happens if communications fail.
THE PRACTICAL DETAILS
Compare how much solar generation matches your electricity demand hour by hour. Direct use avoids buying that electricity at the import rate. Surplus can be stored or exported, depending on the value available in each route and your export arrangements.
Check Ofgem’s export guidanceBattery arbitrage is the difference between what energy costs to put into a battery and what it is worth when discharged. For example, at 90% round-trip efficiency, putting in 10 kWh leaves about 9 kWh to use. The price difference needs to cover the lost energy, battery wear and service costs.
Try a reference estimateThe plan needs both kWh, the energy the battery can hold, and kW, how quickly it can charge or discharge. Add usable capacity, reserve settings, the inverter limit, the site’s import and export limits and any warranty conditions. These determine which opportunities can actually be delivered.
Work with your own tariff and usageOn-site savings, supplier export payments and contracted flexibility are different sources of value. Flexibility means changing when the site imports or exports in response to a request. Check the route to market, metering, availability and settlement terms before assuming payments. Check that two proposed services can use the same equipment without conflicting commitments.
