Everything you need to know about going solar with Shree Abhi Engineering

What government subsidy am I eligible for as a homeowner?
Subsidy

Under the PM Surya Ghar: Muft Bijli Yojana, the Central Government provides a direct subsidy for rooftop solar installations:

  • Independent houses: Flat subsidy of ₹78,000 for systems up to 3 kW
  • Gated community / apartment residents: ₹18,000 per kW (shared/common area installations)
  • Additional state-level subsidies may apply depending on your location in Tamil Nadu.

We handle the complete subsidy application and documentation process on your behalf — no paperwork hassle for you.

How long does it take to recover my investment (payback period)?
Savings

For most residential customers, the payback period is 4 to 6 years after subsidy. For commercial and industrial installations (no subsidy, but higher consumption), payback typically ranges from 3 to 5 years due to higher savings on commercial tariffs.

Solar panels have a performance warranty of 25 years, which means you enjoy 20+ years of virtually free electricity after recovering your cost. On average, our customers save ₹3,000 – ₹8,000 per month depending on system size and consumption.

How much maintenance is required after installation?
Process

Solar panels are remarkably low-maintenance. Here's what to expect:

  • Panel cleaning: Once every 2–4 weeks with water (dust and bird droppings are the main performance reducers in Tamil Nadu's climate).
  • Annual inspection: We offer a free annual system checkup covering inverter health, wiring integrity, and mounting structure.
  • Remote monitoring: Our systems come with app-based real-time monitoring — you can track generation, consumption, and savings on your phone.

We provide AMC (Annual Maintenance Contracts) for complete peace of mind.

Will solar panels work effectively during cloudy or rainy days?
Residential

Yes — solar panels generate electricity from diffused sunlight, not just direct sunshine. During overcast or light-rain days, output reduces to roughly 20–40% of peak capacity, but generation continues.

Tamil Nadu enjoys over 300 sunny days per year, making it one of India's best locations for solar. Annual generation estimates we provide are calculated using 10-year historical irradiation data specific to your area, accounting for seasonal cloud cover.

How long does the complete solar installation process take?
Installation

For a standard residential rooftop system, the entire process from survey to commissioning typically takes 7 to 14 working days. Here's a general timeline:

  • Site survey & design: 1–2 days — our engineers assess your roof, load consumption, and shadow analysis.
  • Approvals & DISCOM application: 3–7 days — we handle all paperwork with TANGEDCO/TNEB on your behalf.
  • Physical installation: 1–2 days — panel mounting, inverter setup, and grid connection.
  • Net metering & commissioning: 2–3 days — final inspection, meter installation, and system go-live.

Commercial and industrial projects may take longer depending on system size and site conditions. We provide a detailed project timeline before work begins.
