Battery Energy Storage Systems (BESS)
Store energy. Use it when you need it.
SolarQube provides BESS in Salem and across Tamil Nadu. Pair your solar system — or your existing grid connection — with battery storage so power is available on your terms: during outages, after sunset, or whenever tariffs and demand charges are highest.

A Battery Energy Storage System (BESS) is a bank of rechargeable batteries, paired with an inverter and smart controller, that stores electricity for later use. It can charge from your solar panels during the day, or from the grid during low-tariff hours, and release that stored power exactly when you need it — during a power cut, in the evening after the sun goes down, or at times when drawing from the grid is most expensive.
In short: it turns intermittent, time-bound power generation into power you can use on your own schedule.
Why BESS?
Energy Storage
Capture power when it's generated and hold it for later use.
Backup Power
Keep essential loads running automatically during grid outages.
Maximize Solar Usage
Store excess daytime solar instead of exporting it at low rates.
Manage Peak Demand
Draw from stored battery power instead of paying peak-hour tariffs.
BESS Applications
Residential
Solar storage & backup — keep lights, fans, and essential appliances running through outages.
Commercial
Energy management & backup — protect critical operations and shift load away from peak tariffs.
Industrial
Peak demand & large-scale storage — reduce demand charges and improve power reliability at scale.
Solar + BESS
A solar system generates the most power in the middle of the day — often more than your home or business can use right then. Without storage, that extra energy is exported back to the grid, usually at a lower rate than what you pay to import power. Add a battery, and that excess daytime solar is stored on-site instead, ready to power your home or facility in the evening, overnight, or during a grid outage. The result: a higher share of your own solar generation is actually used by you, your electricity bill drops further, and you gain a reliable backup layer — all from the same rooftop system.

FAQ
BESS stands for Battery Energy Storage System — a battery bank with an inverter and controller that stores electricity from solar or the grid and supplies it back when you need it.
Yes — BESS pairs naturally with rooftop solar. It stores the excess power your panels generate during the day so you can use it after sunset or during an outage, instead of exporting it to the grid.
Backup duration depends on battery capacity and the loads you want to power. During your site visit, we'll size the system around which appliances need to stay on and for how long.
We size BESS based on your daily energy consumption, the specific loads you want backed up, your existing (or planned) solar capacity, and how much peak-demand or outage protection you need.
Yes. We use certified battery systems with built-in protection circuits, and our engineers follow standard electrical safety practices for installation, earthing, and enclosure placement.
Cost depends on battery capacity, backup requirements, and whether it's paired with a new or existing solar system. Share your requirements with us for a tailored quote.
