# Battery storage or solar first — which does your business need? Most businesses benefit from solar first, because generating your own power gives the biggest, most direct saving. Battery storage then adds value on top by storing that generation for later. But for sites with little roof or a strong peak/off-peak tariff gap, a battery alone can still pay. ## Solar usually comes first Generating electricity on site replaces expensive grid power directly, which is the core saving. If you have suitable roof space and daytime demand, solar is normally the first and biggest step. ## Where battery storage earns its place A battery stores solar for use in the evening, increasing how much of your own generation you use rather than exporting it cheaply. It also shifts cheap off-peak grid energy into expensive peak periods and helps manage demand peaks. ## When a battery alone makes sense If your roof is small or unsuitable, or you have a big gap between peak and off-peak rates, a standalone battery can still cut costs without any solar. The right answer depends on your site, demand and tariff. ## Frequently asked questions **Can I add a battery later, after solar?** Often yes — many businesses start with solar and add storage as needs evolve. We design with your longer-term plans in mind so future additions are straightforward. **How do I know which is right for us?** It comes down to your roof, energy-use pattern and tariff.
