Solar Questions, Clearly Answered.

Eligible residential households in Tamil Nadu can currently receive total financial assistance of up to ₹1,00,000 for rooftop solar. This includes up to ₹78,000 under PM Surya Ghar and an additional Tamil Nadu state subsidy of up to ₹22,000. The exact amount depends on system capacity, eligibility and current scheme conditions.

There is no single correct price for a 3 kW rooftop solar system. The final cost depends on the solar panels and inverter selected, mounting structure, roof conditions, electrical work, cable length, safety equipment and installation scope. Eligible residential customers may also reduce their effective cost through applicable solar subsidies. A proper quotation should therefore compare the complete system and service scope, not just the price per kW.

With a grid-connected rooftop solar system, the electricity generated is first used to meet your property's electricity needs. When the system produces more than you are using, surplus energy can be exported to the grid through the approved metering arrangement. When solar generation is insufficient, electricity is drawn from the grid. The final billing treatment follows the applicable Tamil Nadu rooftop-solar and metering rules.

A properly sized rooftop solar system in cities like Coimbatore, Tiruvannamalai, Viluppuram, Erode, etc. can significantly reduce the electricity you need to purchase from the grid, and some homes may achieve savings of up to around 90%. The actual reduction depends on electricity consumption, solar generation, system capacity, daytime usage, applicable tariff and how exported solar energy is accounted for. Solar should be sized around realistic savings—not exaggerated projections.

The right solar capacity should be based mainly on your actual electricity consumption, roof space, shading, sanctioned load and daytime usage. Two homes with similar electricity bills may still need different systems. Scaler Solar therefore recommends sizing the system from your real consumption and site conditions rather than automatically installing the largest capacity your roof can accommodate.

There is no single system size for every apartment. We look at common-area electricity usage, usable rooftop, daytime consumption, applicable connection and the association’s objectives before recommending capacity.

There is no single capacity that suits every business. We look at electricity usage, roof availability, operating pattern, applicable connection and project objectives before recommending a system size.

The result depends on electricity usage, daytime consumption, tariff, roof feasibility and the final system design. Scaler Solar presents the assumptions clearly instead of using a generic savings percentage.

Solar can help offset electricity used by common services such as lifts, pumps, lighting, STP and shared facilities, depending on the property’s actual load profile and system design.

In general, 1 kW installation requires approximately 60 - 70 Sq ft. But overall roof space requirement depends on recommended capacity, module layout, shading, setbacks, access pathways and mounting design. Usable area is confirmed during the site survey.

Yes, many commercial systems are installed on suitable metal roofs. The mounting method, roof condition, sheet profile and structural considerations must be reviewed before final design.
