Frequently Asked Questions

A solar rooftop system is a power generation setup where electricity-generating solar panels are mounted on the roof of a residential or commercial building. It captures sunlight and converts it directly into electricity to power your home or business.

It is a simple but fascinating process:

  • Sunlight Hits: Sunlight (photons) hits the solar panels.
  • Energy is Created: The panels (made of semiconductor materials like silicon) absorb this energy, knocking electrons loose.
  • Electricity Flows: This movement creates Direct Current (DC) electricity.
  • Power is Converted: The DC electricity flows to an inverter, which converts it into AC—the standard electricity used by your appliances and the EB grid.

Cost varies by size and component quality. A good 1kW on-grid system costs ₹60,000-₹70,000. Larger systems have a lower per-kW rate.

The primary benefit is a drastic reduction in your electricity bills. You generate your own free power instead of buying it from the grid. It also provides energy security against rising EB tariffs and helps the environment.

Solar power is 100% clean and renewable.

  • Reduce Carbon Footprint: You stop burning fossil fuels, preventing the release of harmful greenhouse gases.
  • Improve Air Quality: Solar produces zero air pollution.
  • Conserve Water: Unlike traditional power plants, solar panels require no water to generate power.

Typical payback 3-5 years. After that, electricity generated is free for 20+ years.

Savings depend on your system size and consumption. Many residential, their bills reduced by up to 90%. With Net Metering, any extra electricity you generate is sent back to the grid, earning credits that lower your bill further.

We are a dedicated local team providing safe, efficient, long-lasting solar systems built for Indian conditions. We prioritize transparency, quality components, and long-term relationships.

Solar systems are long-term assets. Panels come with 25–30 years performance warranty. Inverters usually have a 10-year warranty and may need one replacement in the system’s lifetime.

Yes. Homes with solar installations are more desirable because buyers appreciate lower monthly electricity bills.

  • Solar Module: A single, pre-assembled unit of solar cells wired under glass.
  • Solar Panel: Broad term used for either a single module or an entire array.

  • Solar Panels: To capture sunlight.
  • Inverter: Converts DC to usable AC.
  • Mounting Structures: Non-corrosive frame holding panels.
  • Cables & Safety Devices: AC/DC boxes and wiring for protection.

Cost is calculated based on:

  • System Size (kW)
  • Component Quality (panels & inverters)
  • Roof Type
  • Installation Complexity

Yes. Many banks provide Green Loans/Solar Loans. Often, your savings cover the EMI.

Your savings depend on your current electricity usage, tariff slab, and solar production. We calculate this during our free consultation.

  • Current Tariff
  • System Performance
  • Net Metering benefits

Panel prices have stabilized. Subsidies are reducing. Waiting usually costs more in electricity bills.

No. Our proposal includes components, installation, wiring, safety devices, and EB processing fees.

Net Metering is TANGEDCO’s billing mechanism for solar users.

  • Bi-directional meter installed.
  • Records Import vs Export.
  • You pay only for net units.
  • Excess export credited to next bill.

As of 2025, the subsidy is:

  • ₹30,000 per kW for first 2kW.
  • ₹18,000 for the 3rd kW.
  • Max subsidy: ₹78,000.

  • Indian citizens.
  • Residential homeowners.
  • Domestic EB connection holders.
  • Must not have availed previous solar subsidy.

We manage the full process.

  • Register on PM Surya Ghar portal.
  • Submit completion reports via USRP after installation.

  • Recent EB Bill.
  • Aadhaar Card.
  • Passport-sized photo.
  • Property ownership proof.
  • Bank account details.

Feasibility approval takes 1–2 weeks. Subsidy payment arrives within ~30 days after commissioning and certificate upload.

The 2024/2025 subsidy scheme offering up to ₹78,000 subsidy for residential rooftop solar.

An On-Grid system connects to EB and exports excess electricity.

  • Best choice for 99% of homes.

An Off-Grid system works independently with batteries.

  • Recommended only for remote locations without EB connection.

A Hybrid system is On-Grid with battery backup.

  • Ideal for savings + backup power.

  • On-Grid: NO (Anti-Islanding safety).
  • Hybrid/Off-Grid: YES (Battery backup).

  • Pros: Backup power.
  • Cons: High cost and periodic replacement.
  • Recommendation: Choose Hybrid-ready inverter.

  • Monocrystalline (Black): Premium, high efficiency.
  • Polycrystalline (Blue): Budget-friendly.

Monocrystalline panels handle heat better and produce more power in limited space.

The inverter converts DC to AC and controls safety and performance.

Rule of thumb: 80 sq.ft per kW.

  • 1kW = ~80 sq.ft
  • 3kW = ~240 sq.ft
  • 5kW = ~400 sq.ft

Yes, we install on all roof types.

  • Concrete roofs: No drilling (non-penetrating mounts).
  • Metal sheet: Seam clamps.
  • Tiled: Waterproof flashing.
  • Avoid asbestos roofs for safety.

  • Best: South-facing.
  • Good: East/West.
  • Avoid: North.

Shadows reduce solar output. We conduct a survey to ensure shadow-free installation.

  • Approvals: 2–4 weeks.
  • Installation: 1–2 days.
  • Net Metering: 1–2 weeks post-installation.

Yes. We offer a 100% free technical site survey.

No. We use non-penetrating mounts and seam clamps. No slab drilling = no leaks.

No. Only TANGEDCO approval is required, and we handle it.

No. Panels have no moving parts. Just keep them clean.

  • Use soft brush & plain water.
  • Clean in early morning or evening.
  • Once a month if panel is dusty.

Panels have toughened glass. Damaged panels can be replaced individually.

Yes. Our structures are corrosion-resistant and cyclone-rated.

Your inverter connects to Wi-Fi and shows live power generation in a mobile app.

Yes. Our AMC includes professional cleaning and technical inspections.

  • Panel Warranty: 25–30 years.
  • Inverter Warranty: 5–10 years.
  • Workmanship Warranty: Covers installation quality.

  • Product Warranty: Covers defects (10–12 years).
  • Performance Warranty: Ensures 80% power after 25–30 years.
