How much usable storage?
Ask for usable capacity, charge and discharge limits, and a design based on your usage rather than the biggest available battery.
NEW SOLAR + BATTERY · BRISTOL
Make more of
your solar plans.
Considering storage? Look at solar panels and a battery as one new system, designed around your home and how you use electricity.
Start with your day,
not a battery size.
A battery can store electricity for use later. Whether it suits your project depends on your generation, consumption, tariff, budget and the system design.
Ask the provider to compare a panels-only design with a new solar-and-battery design using the same assumptions. That makes the extra cost and expected benefit easier to assess.
