Frequently Asked Questions

Solar energy is electricity generated from sunlight using photovoltaic (PV) panels. Solar panels contain silicon cells that convert sunlight directly into direct current (DC) electricity. An inverter then converts this DC power into alternating current (AC), which is the type of electricity used by your home appliances. Any excess electricity can be stored in batteries (hybrid system), fed back to the grid (on-grid system), or both.

Solar is suitable for most homes and businesses in India. Key requirements are: a south-facing roof with minimal shading, adequate roof area (approx. 10 sq. ft. per 100W), and a monthly electricity bill of at least ₹1,500. Our engineers will conduct a free site survey to assess your specific situation and recommend the ideal system.

Quality Tier-1 solar panels are warrantied for 25 years of performance output. In practice, they often last 30–35 years. They lose about 0.5–0.8% efficiency per year, meaning after 25 years they still produce around 80% of their original rated output. Inverters typically carry a 5–10 year warranty and may need replacement once in the system's lifetime.

We use only Tier-1 rated solar panels from globally recognized manufacturers including Adani, Waaree, Tata Power Solar, Vikram Solar, and Longi Solar — all MNRE approved. For inverters, we work with Growatt, Solis, Delta, and SMA depending on system size and customer requirements.

Solar system costs in 2025 (before subsidy):

• 1 kW On-Grid: ~₹60,000 – ₹75,000
• 2 kW On-Grid: ~₹1,10,000 – ₹1,30,000
• 3 kW On-Grid: ~₹1,55,000 – ₹1,80,000
• 5 kW On-Grid: ~₹2,50,000 – ₹2,80,000
• 10 kW Commercial: ~₹4,50,000 – ₹5,00,000

After PM Surya Ghar subsidy, the effective cost for a 3 kW system can be as low as ₹87,000.

Under the PM Surya Ghar Muft Bijli Yojana (2024):

• 1 kW: ₹30,000 subsidy
• 2 kW: ₹60,000 subsidy
• 3 kW: ₹78,000 subsidy (max for residential)
• Above 3 kW: ₹78,000 (capped)

Commercial and industrial systems do not qualify for PM Surya Ghar, but state-level incentives and accelerated depreciation benefits may apply. Our team handles all subsidy paperwork for free.

Savings depend on your current bill and system size. As a benchmark:

• ₹3,000/month bill → 3 kW system → saves ~₹2,500/month
• ₹5,000/month bill → 5 kW system → saves ~₹4,200/month
• ₹10,000/month bill → 10 kW system → saves ~₹8,500/month

Most customers see 80–100% reduction in electricity bills. On-grid systems with net metering can bring your bill to near zero.

For residential on-grid systems with PM Surya Ghar subsidy, the payback period is typically 3–5 years. For commercial systems without subsidy, it's 4–6 years. Over a 25-year panel life, the total savings are 4–6x the initial investment. We provide a detailed ROI report with every free site survey.

Yes! We have tie-ups with nationalized banks and NBFCs for solar loans at attractive interest rates (6.5%–10% p.a.). We also offer 0% EMI options for select projects in partnership with SECI and state government schemes. Our team will help you find the best financing option based on your credit profile.

Typical installation timelines:

• Residential (1–5 kW): 1–2 days for physical installation
• Commercial (5–50 kW): 3–7 days
• Total process (survey to commissioning): 15–30 working days

This includes: free survey → custom design → permits & DISCOM approval → installation → inspection → net-meter application. Our team tracks every step and keeps you updated via WhatsApp.

No. Our mounting systems use non-penetrating or minimal penetration techniques. For RCC roofs, we use ballasted mounts that don't require drilling. For metal sheet roofs, we use clamp-based systems. All mount points are sealed with waterproof sealant. We provide a 5-year workmanship warranty covering any water leakage caused by the installation.

Yes, 100%. We handle the entire paperwork from application to commissioning:

1. DISCOM technical feasibility application
2. Net metering agreement
3. Meter change to bi-directional meter
4. Final commissioning certificate

You don't need to visit any government office. We manage everything on your behalf.

Yes! While south-facing roofs give maximum output in India, east and west-facing panels still produce 80–90% of peak output. We can also install panels at an optimal tilt angle to compensate. During the free site survey, our engineers will conduct a detailed shading analysis and design the best layout for your specific roof orientation.

Yes! Solar panels generate electricity even on overcast days — typically at 10–30% of peak output on heavily cloudy days and 50–70% on light overcast days. India averages 250–300 sunny days per year, and most solar systems are sized to account for seasonal variation. Hybrid systems with battery backup ensure power even on fully cloudy periods.

With a standard on-grid system, solar generation stops during a power cut for safety reasons (to prevent back-feeding power to the grid where linesmen may be working). However, a hybrid system with battery backup continues to power your home during an outage using stored battery energy. If uninterrupted power is critical for you, we recommend a hybrid system.

Net metering is a billing mechanism where your electricity meter runs backwards when your solar panels produce more electricity than you consume. The excess units are credited to your account and adjusted in your monthly bill. At the end of the billing cycle, you only pay for the net electricity consumed (grid units minus solar units exported). In most states, export rates are ₹2–₹4 per unit.

Every Wemega installation comes with a monitoring system accessible via a free app (iOS and Android). You can track:

• Live power generation (kW)
• Daily / monthly / yearly energy production (kWh)
• Estimated savings in ₹
• CO₂ emissions saved
• System health alerts

Our engineers also monitor your system remotely and alert you if performance drops below expected levels.

A Solar Atta Chakki (Solar Flour Mill) runs entirely on solar power instead of grid electricity or diesel. Available in 5HP, 7.5HP, and 10HP capacities:

• 5HP Solar Atta Chakki: ~₹3,50,000 – ₹4,00,000
• 7.5HP: ~₹4,50,000 – ₹5,50,000
• 10HP: ~₹6,00,000 – ₹7,50,000

ROI is typically 3–4 years with no electricity or diesel cost. Optional battery backup is available for cloudy-day operation.

PM-KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthan Mahabhiyan) Component C provides solar pumps to farmers:

• Central subsidy: 30% of benchmark cost
• State subsidy: 30% of benchmark cost (varies by state)
• Farmer contribution: Only 10–40%

This means farmers can get a solar pump at 10–40% of actual cost. Our team files all PM-KUSUM applications and liaises with state DISCOM / agriculture departments on your behalf.

We install solar submersible and surface pumps from 1HP to 10HP:

• 1–2 HP: Small gardens, domestic bore wells
• 3–5 HP: Medium farms (2–5 acres), irrigation
• 7.5 HP: Large farms, commercial irrigation
• 10 HP: Very large farms, water supply projects

The system includes solar panels, a VFD (Variable Frequency Drive) controller, submersible/surface pump, mounting structure, and all wiring.
