What Is Solar Batteries?
A solar battery stores surplus solar generation for use later — most commonly during a grid power cut, when a standard on-grid system without a battery shuts down for safety even though the sun is shining. Battery storage requires a compatible hybrid inverter and is typically added for essential loads (lights, fans, Wi-Fi, refrigeration) rather than sized to run an entire home.
Benefits of Solar Batteries
Power During Outages
Essential loads keep running when the grid goes down, unlike a standard on-grid system.
Lithium Chemistry Options
We supply lithium battery storage, offering better lifespan and depth-of-discharge than older lead-acid options.
Sized to Essential Load
Battery capacity is sized around what you actually need to back up, keeping cost proportionate.
Works With New or Existing Systems
Battery storage can be added to a new hybrid installation or retrofitted to some existing systems with inverter compatibility.
Warranty-Backed Storage
Batteries carry manufacturer warranty support, typically 5-10 years depending on brand and chemistry.
Monitoring Included
Battery charge/discharge status is visible through the same monitoring app as your inverter.
Do You Need a Battery?
If your area rarely loses grid power, a standard on-grid system without a battery is usually the more cost-effective choice. If outages are frequent or you have essential equipment that must keep running — medical devices, work-from-home setups, refrigeration — a battery-backed hybrid system is worth the additional upfront cost. We'll help you weigh this during your site survey.
Up to \u20B91,08,000 Government Subsidy Available — as applicable under current Central + State benefits for eligible residential rooftop solar installations in Uttar Pradesh. Eligibility depends on system size, applicable government guidelines, approvals and scheme eligibility, and is subject to change.
Installation Process
Free Site Survey
We assess your roof, load pattern and existing electrical setup.
Design & Quotation
System size, component brand and itemised pricing are shared upfront.
Load & Backup Assessment
We identify which loads you want backed up and size the battery accordingly.
Installation
Battery is installed and configured alongside your hybrid inverter, with backup circuits wired separately if needed.
Commissioning & Handover
System is tested, verified and warranty documents are handed over.
Why Choose Sunroof Solar Solutions
We only recommend battery storage where it genuinely fits your needs and budget — not as a default upsell — and size it around your actual backup requirements rather than a generic package.
Frequently Asked Questions
It depends on whether your existing inverter is hybrid-compatible. If it's a standard string inverter, you'll typically need an inverter upgrade alongside the battery.
This depends entirely on battery capacity and which loads are connected — we size this specifically to your essential-load requirements during the site survey.
Lithium batteries offer longer lifespan, better depth-of-discharge and a smaller footprint than lead-acid, though at a higher upfront cost. We primarily recommend lithium for new installations.
