Solutions — by configuration
How does a solar + battery storage (solar + BESS) system work?
A solar + BESS system pairs a solar plant with battery storage so midday generation is stored and dispatched when it is worth most — into evening peaks, high-tariff Time-of-Day windows or outages. Alpha Devraj ESS designs, sizes and delivers integrated solar + storage systems for commercial, industrial and utility customers across India.
How it works
Watch it run.
Why pair solar with storage?
Solar generates on its own schedule — a bell curve centred on midday. Your loads and tariffs do not follow that curve. Storage decouples generation from consumption: excess midday energy charges the battery, and the battery discharges into evening peaks, Time-of-Day windows or demand spikes. The result is higher self-consumption, lower demand charges and solar energy that earns its full value.
How we size the system
We start from your load profile and tariff structure, not from a product catalogue. A load study establishes your consumption pattern, peak demand and ToD exposure; we then model solar and battery sizes together to find the configuration with the best payback. You see the economics before any hardware is specified.
What we deliver
A complete system: solar plant, LFP battery storage in cabinet or container form, power conversion, and an EMS that runs the daily charge-discharge dispatch automatically. We handle design, engineering, procurement, installation and commissioning, with long-term monitoring and O&M available.
Common questions
Can storage be added to an existing solar plant?
Yes. We retrofit storage onto existing solar plants as well as designing new hybrid systems from scratch. Adding storage lets you self-consume more of your generation and shift it into high-value windows.
What battery size do I need for my solar plant?
It depends on your load profile and tariff, not just the solar capacity. As a starting point, C&I systems are often sized to absorb the midday surplus and cover the evening peak window; we confirm the size with a load study and a payback model before you commit.
