ZeroBill Solar System™

Begin with your bill and your roof.

Share recent electricity bills and discuss roof access, shading, ownership permissions and future loads. A site survey reviews structure, mounting, waterproofing considerations, cable routes and electrical safety before a final design.

A proposal with the details that matter.

Review capacity, named equipment, expected generation assumptions, itemised cost, warranty coverage, exclusions and project responsibilities. Ask how seasonal generation and your consumption pattern affect the expected benefit.

Subsidy and utility coordination.

Subsidy eligibility depends on current PM Surya Ghar rules and consumer and system requirements. Vishan Solar assists with applicable documentation and net-meter coordination. Customers complete required identity, banking and consent steps; authority decisions and timelines cannot be guaranteed.

Verify current information on the official PM Surya Ghar portal and TNPDCL rooftop solar portal.

Understand financing before deciding.

If financing is being considered, compare the total repayable amount, interest, fees and monthly instalments against your household budget. Availability and terms depend on the selected lender and applicant eligibility. Vishan Solar is not a lender.

A property-specific savings assessment.

A monthly bill alone cannot establish capacity, savings or payback. Request an assessment that includes tariff, sanctioned load, usable roof, shading, generation assumptions, fixed charges and any financing costs.

Support after installation.

Monitoring guidance, a clear handover and a direct point of contact help you understand your system. Maintenance scope and manufacturer warranty terms vary and must be stated in your proposal. A standard on-grid system does not provide power during a grid outage; discuss any backup requirement separately.
