Battery storage
Keep more of what the roof makes.
Storage adds timing to solar. Capacity, reserve strategy and monitoring should be designed around the actual load rather than a generic battery size.
STORE / SHIFT / CONTROL
Storage has a job to do
Do not buy a battery before you know the job.
Self-consumption, evening use, backup and tariff strategy are different objectives. Capacity and control should follow the objective.

USE MORE SOLAR
Move daytime generation into later household or business demand.
PLAN FOR BACKUP
Define which loads matter and what the installed system can support.
CONTROL THE FLOW
Use monitoring and system settings to make storage behaviour visible.
DESIGNED TO STAY USEFUL
Not just panels on a roof.
Design around demand
Roof geometry matters. So do usage patterns, future EV charging and when the building actually needs power.
Build the details in
Access, cable routes, inverter position and serviceability should be solved before installation day.
Keep it visible
Monitoring should make generation, storage and unusual behaviour understandable after handover.
Before you buy
Questions worth asking before anyone drills the roof.
How do you decide how many panels I need?
Start with consumption, usable roof area, orientation, shading and how the building is used during the day. A useful design is not simply the maximum number of panels that fit.
Do I need a battery?
Not automatically. Storage makes sense when the load profile, backup goals or energy strategy justify it. The battery should be sized with the generation profile, not sold as a separate gadget.
Can the system be prepared for an EV or heat pump later?
That future demand belongs in the design brief. Cable routes, inverter choice, available roof capacity and storage strategy can all be considered before installation.
What should a quote actually show?
At minimum, the proposed system components, assumptions, installation scope, monitoring approach and any project-specific warranty or performance terms that have been verified.
