Question 1

What size solar system do I need?

Accepted Answer

System size depends on your annual electricity consumption, local peak sun hours, roof orientation and shading. As a starting point, our calculator converts your monthly bill into an estimated annual consumption and then sizes a system that could offset most of it. A site survey confirms the final design.

Question 2

How much does rooftop solar cost?

Accepted Answer

Cost varies with system size, structure type, cable runs, mounting height and component selection. Our calculator uses a configurable cost-per-kW assumption so you get an indicative range; the final figure comes from your written proposal.

Question 3

How much can I save with solar?

Accepted Answer

Savings depend on how much of the generation you consume directly, your tariff slab and net-metering rules in your state. A well-designed rooftop system is typically designed to offset a large share of daytime consumption, potentially reducing your grid bill significantly.

Question 4

Is battery backup necessary?

Accepted Answer

Not always. If your area has a stable supply and net metering is available, a grid-tied system without a battery is usually the most cost-effective. Battery storage makes sense when you need essential loads to keep running during outages.

Question 5

How long does solar installation take?

Accepted Answer

Physical installation for a typical residential rooftop system is usually completed in a few days. Overall timelines also include design approval, DISCOM application, material delivery, commissioning and meter installation.

Question 6

What maintenance does a solar system require?

Accepted Answer

Mostly periodic module cleaning and visual inspection, plus occasional checks of mounting hardware, cabling, earthing and inverter health. We help you plan a simple maintenance routine.

Question 7

How long do solar panels last?

Accepted Answer

Modern modules are designed for a long service life, typically with multi-decade performance warranties from manufacturers and a gradual annual degradation in output. Our estimates model this degradation rather than assuming constant output.

Question 8

Can solar work during a power cut?

Accepted Answer

A standard grid-tied system shuts down during an outage for safety. To keep loads running you need a hybrid inverter with battery storage, or a system configured with backup output.

Question 9

What happens during a power cut?

Accepted Answer

Without a battery, generation pauses until the grid returns. With a hybrid system, selected essential loads continue running from the battery, and solar can recharge the battery during the day.

Question 10

Is net metering available?

Accepted Answer

Net metering availability, capacity limits and settlement rules are set by your state DISCOM and change from time to time. We check the current rules applicable to your connection during the proposal stage.

Question 11

Are government subsidies available?

Accepted Answer

Subsidy and incentive schemes exist for certain categories of consumers, but eligibility, amounts and processes depend on current government and DISCOM rules. We never quote a fixed subsidy without verifying the scheme applicable to you.

Question 12

How do I apply for solar subsidy?

Accepted Answer

Applications are made through the official portals and processes notified by the government and your DISCOM, typically with a registered vendor. We guide you through documentation and coordination where the scheme applies.

Question 13

Do you provide installation and after-sales support?

Accepted Answer

Yes. We handle system design, installation and commissioning, and support you afterwards with maintenance guidance, warranty coordination and performance queries.
