Frequently Asked Questions

Everything you need to know about solar energy, installation, costs, and benefits.

Savings & Bills

Solar Savings

How much can I save on electricity bills with solar?

With a properly sized solar system, you can reduce your electricity bills by 70–100%. The exact savings depend on your system size, daily sunlight hours in your area, and your energy consumption pattern. Most customers in Prayagraj recover their investment within 4–6 years.

What is net metering and how does it benefit me?

Net metering allows you to export excess solar electricity back to the grid and earn credits, which are adjusted against units consumed from the grid at night. This means your meter literally runs backwards when your panels produce more than you use — reducing your bill further.

How much does a solar system cost in Prayagraj?

A 1kW on-grid residential system typically costs ₹40,000–₹70,000 before subsidy. After government subsidy (up to 40% for the first 2kW), the effective cost reduces significantly. We provide transparent, no-hidden-cost quotes — call us for an exact estimate.

Is there any government subsidy available?

Yes! Under the PM Surya Ghar Muft Bijli Yojana, residential customers can get up to 40% subsidy for systems up to 2kW, and 20% for the 2–3kW portion. Farmers can benefit from PM-KUSUM scheme for solar pumps. We handle all subsidy paperwork for you.

Installation

Installation Process

How long does the installation take?

Residential solar system installation typically takes 1–2 days. Larger commercial systems may take 3–7 days. The entire process from enquiry to commissioning — including site survey, design, procurement, installation, and net metering — typically takes 2–4 weeks.

How much roof space do I need for solar panels?

Approximately 10–12 sq. ft. of shadow-free roof space is required per 100 Watts of solar capacity. So a 3kW system needs about 300–360 sq. ft. of roof area. Our engineers will assess your roof during a free site survey and confirm the feasibility.

Will solar work on my roof type?

Solar panels can be installed on almost all roof types — RCC (flat/terrace), sloped/tiled roofs, tin/metal sheets, and even on ground mounts. We design custom mounting structures for every roof type. Our engineers will confirm suitability during the free site visit.

Do I need to get permission from the electricity department?

For net metering (on-grid systems), an application to UPPCL/PVVNL is required. We handle this entire process — including technical inspection, paperwork, and getting the bi-directional meter installed. For off-grid systems, no grid permission is needed.

Performance

System Performance

Will solar panels work on cloudy or rainy days?

Yes! Solar panels generate electricity from daylight, not direct sunlight. On cloudy days, output reduces to 10–25% of peak capacity. Prayagraj has 300+ sunny days a year, which is excellent for solar. On-grid systems supplement from the grid on low-production days.

How long do solar panels last?

Solar panels typically last 25–30 years. They degrade slowly — about 0.5–1% per year. After 25 years, panels still produce about 80% of their original capacity. Inverters last 10–15 years. We provide panels with a 25-year manufacturer performance warranty.

What maintenance is required for solar panels?

Solar panels require minimal maintenance. Occasional cleaning with water (every 1–3 months) to remove dust is recommended. We offer Annual Maintenance Contracts (AMC) that include regular inspections, panel cleaning, inverter checks, and performance monitoring — keeping your system at peak efficiency.

What happens during power cuts?

On-grid systems shut down automatically during grid outages (for safety). Off-grid and Hybrid systems with battery backup continue to power your home. If you have frequent power cuts, we recommend an off-grid or hybrid system with sufficient battery capacity.

How can I monitor my solar system performance?

Modern inverters come with mobile app monitoring (Android/iOS). You can track daily/monthly energy generation, consumption, savings, and system health in real-time from your smartphone. We assist with setting up the monitoring app after installation.
