Battery storage can shift when a business uses electricity, help use solar generation later and support backup when designed for that purpose. Its value depends on the site's load profile, tariff, connection and operating goals.
Power and energy capacity are different
Power in kW describes how much output can be supplied at a moment. Energy capacity in kWh describes how much energy can be stored. Ask for usable capacity, operating limits and warranty conditions rather than comparing battery names alone.
Solar integration and backup
For an existing solar system, check ownership, connection limits, metering and equipment compatibility. A storage system is not automatically a backup system: islanded operation, protection and critical loads must be designed. Exporting stored energy also requires checking the relevant approval and commercial arrangement.
Assess the complete economics
Compare capital cost, conversion losses, operation, maintenance, financing and battery degradation against the value calculated from actual consumption. Do not count the same stored electricity twice as both saved consumption and export revenue. There is no fixed payback period for every business.
Prepare for a supplier conversation
- One year of bills and hourly or interval consumption, where available.
- Tariff, electricity supplier and connection size.
- Existing solar system and agreements.
- Operating hours, seasonal peaks and critical loads.
- Space, project timing and a clear goal.
