Energy storage
Home battery storage paired with your solar goals
Increase self-consumption, ride through outages, and reduce peak tariffs — with installers who integrate storage alongside PV.
Why add battery storage?
Batteries store midday solar for evening use, support backup loads, and can lower demand charges on time-of-use tariffs.
Marssy Energy's simulator models storage alongside solar so you see a combined savings picture before speaking with installers.
How storage is sized on Marssy Energy
We use your consumption profile and optional solar production to suggest a reasonable capacity band. Final sizing follows site survey and product selection by your EPC.
Marssy Energy does not charge homeowners a marketplace commission and does not charge installers per-lead fees — installers use a flat SaaS subscription.
