Frequently Asked Questions
Everything you need to know about going solar and setting up EV infrastructure with ESSRCPS.
Solar Basics
Understanding Solar Energy
What is the difference between on-grid and off-grid solar?
On-grid systems connect to the utility grid for net metering — you sell excess power back and earn credits, reducing your bill to ₹0. Off-grid systems use batteries and work independently of the grid, ideal for rural areas or locations with unreliable power supply.
How much can I save on my electricity bill with solar?
On-grid systems can reduce your electricity bill by 60–100% depending on your system size and usage. Most residential customers see bills drop from ₹3,000-5,000/month to under ₹500/month. Use our Savings Calculator on the homepage for a personalized estimate.
How long do solar panels last?
Solar panels have a 25–30 year operational lifespan. All ESSRCPS panels come with a 25-year linear performance warranty guaranteeing at least 80% efficiency at end of life. The inverters typically last 10-15 years.
What maintenance do solar panels require?
Solar systems require minimal maintenance. Primarily periodic cleaning (2-4 times/year). Our O&M plans include annual health checks, inverter servicing, and real-time monitoring to flag issues before they become problems.
Do solar panels work on cloudy days?
Yes! Solar panels generate power from diffused sunlight even on cloudy days — typically at 10-25% of peak output. Our systems are designed with India's monsoon season in mind and are fully IP65/IP67 weatherproof.
Subsidies & Finance
Government Schemes & Financing
How much subsidy can I get for residential solar?
Under PM Surya Ghar Muft Bijli Yojana: 30% subsidy for systems up to 2kW (max ₹60,000), and 20% on the 2-3kW portion (total central subsidy capped at ₹78,000). Additional state-level subsidies available in UP, Rajasthan, Gujarat, Maharashtra and more.
Does ESSRCPS help with subsidy paperwork?
Yes, we handle 100% of the subsidy documentation — from eligibility check to DISCOM registration, inspection coordination, and online portal submission. We've processed thousands of successful subsidy claims across India.
Can I get solar installed with zero upfront cost?
Yes! Through our financing partners (SBI, HDFC, Tata Capital, and others), you can install solar with ₹0 down payment via Zero-EMI plans (12-24 months, 0% interest) or Solar Home Loans at 7-9% p.a. Your monthly EMI is often less than your current electricity bill reduction.
What is the typical payback period?
With government subsidies and net metering, residential systems typically pay back in 3-5 years. After payback, you enjoy 20+ more years of near-free electricity. Total ROI over 25 years is typically 300-500% of the initial investment.
Are there subsidies for EV charging stations?
Yes — commercial EV charging stations can be eligible for FAME-II scheme subsidies and state-level EV promotion subsidies. ESSRCPS guides you through the entire process of securing available grants and subsidies.
Installation & Support
Installation Process & After-Sales
How long does solar installation take?
Residential systems (1-10kW) are installed in 1-2 days. Commercial and larger systems (10kW-1MW) typically take 3-14 days depending on complexity. We give you a clear timeline before starting work.
Do I need to do anything during installation?
Very little. Our team handles everything — site survey, civil work, electrical wiring, inverter commissioning, and grid connection paperwork. You just need to ensure roof access and power connection is available on the installation day.
What happens if my solar system develops a fault?
Our remote monitoring system detects faults automatically and alerts both you and our service team. For critical issues, we dispatch a technician within 24 hours. Annual O&M plans include priority support and preventive maintenance visits.
Can I expand my solar system later?
Yes! Our systems are designed for scalability. You can add more panels, a battery storage unit, or an EV charger to your existing installation as your needs grow. We'll ensure compatibility with your existing setup.
How does the ESSRCPS Solar to AC Convertor work?
Our flagship product converts solar DC power directly to AC — running 10+ appliances during the day without needing a battery. When solar output is insufficient, it seamlessly switches to mains or battery backup. It's India's most versatile hybrid solar solution.
