Questions answered.Decisions made clearer.

Sizing depends on annual electricity consumption, daytime load, tariff, sanctioned load, shadow-free roof area and local solar yield. Navonax validates the recommendation through a site survey and bill analysis.

On-grid systems work with the utility grid and generally offer the strongest financial return. Off-grid systems use batteries where the grid is absent or highly unreliable. Hybrid systems combine solar, batteries and the grid.

A standard on-grid inverter shuts down during a grid outage for anti-islanding safety. Backup requires an appropriately designed hybrid or off-grid system with battery storage.

As an initial planning assumption, around 80–110 square feet per kW may be required depending on module rating, access paths, setbacks, tilt, roof obstructions and layout.

A bidirectional meter records electricity imported from the grid and eligible surplus solar electricity exported to it. Billing treatment and capacity limits depend on the applicable state and DISCOM regulations.

The central residential rooftop scheme applies subject to eligibility, approved process, DCR and technical requirements, commissioning and verification. Commercial and industrial consumers are generally not eligible for residential CFA.

Quality PV modules are designed for a useful life of 25 years or more. Inverters, protection equipment and batteries have different service lives and should be maintained or replaced as required.

Yes, panels generate whenever usable light is available, but output varies with irradiation, temperature, cloud cover, soiling and shading. Annual estimates account for seasonal variation.

Planned cleaning, visual inspection, electrical checks, structure and fastener review, earthing tests, monitoring analysis and timely fault resolution help protect generation and safety.

Solar can offset a large portion of energy charges when correctly sized, but fixed charges, minimum charges, taxes, night consumption and DISCOM settlement rules may remain.

Share the latest electricity bills, site location, roof details, sanctioned load, operating hours and your objectives. For battery systems, an appliance/load schedule and required backup duration are essential.

Yes. Navonax can support documentation, coordination, installation records, testing, commissioning and applicable portal or DISCOM workflows within the agreed project scope.
