A clearer way to plan solar.
Useful answers before you compare systems or request a proposal.
How do you decide the system size?
We begin with your electricity use, usable roof area and shade. Those details help identify a sensible starting capacity. A site survey, roof assessment and connection check are still needed before a final design. Try the solar calculator to explore a first estimate.
Will every roof need the same panel layout?
No. Roof shape, orientation, obstructions and access paths change the usable area. Panels must fit the building safely while leaving room for installation and future maintenance. A layout that looks good in a quick estimate can change after the roof is measured in person.
Can the calculator give me a final price or payback?
The public calculator estimates physical system size, not a final financial return. Equipment choice, site work, electricity tariff and current eligibility rules affect a proposal. RENQ can discuss these details for your project instead of presenting one price or savings figure as if it applied to every home or business.
Is planning different for a business?
The first questions are similar, but a commercial site may have different operating hours, roof access, sanctioned load and approval needs. The design should reflect when the building uses power, not just its total bill. See solar for business or share your site details with the team.
What happens after installation?
RENQ's approved five-year comprehensive maintenance plan includes quarterly preventive visits, phone and on-site support, daily online monitoring and warranty-claim assistance. Panel cleaning is excluded. Read the service details and discuss the plan for your system before work begins.

Customer testimonials
Read all reviewsWhat our customers say.
“We are happy with our decision to install a 3.3 kWp solar power system with RenQ. The team was supportive throughout the process, from installation to completion. We appreciate their professional service and commitment to helping us move towards clean, renewable energy.”
“Installing solar with RenQ has made a remarkable difference in our electricity expenses. With a 4.4 kW Adani solar panel system and a 4 kW single-phase SolarEdge inverter, our monthly electricity bill has dropped from around ₹3,000 to just ₹200–₹250, covering mainly the fixed charges. We are happy with the savings and glad we chose solar energy with RenQ.”
