About Solar Power & This Tool

Welcome to the advanced Solar Requirement Estimator (2026 Innovation Edition). This tool is designed for students, homeowners, and researchers to understand the potential of renewable energy.

How does this calculation work?

Solar panel output depends on geography and sunlight hours. This tool uses the formula: (Daily Usage ÷ Sun Hours) × 1.3 (Efficiency Loss Factor). We also account for shadow loss and battery efficiency to give you a realistic estimate.

Why switch to Solar?

• Reduce Bills: Save up to 90% on electricity bills.
• Green Energy: Reduce your Carbon Footprint (CO2).
• High ROI: Most systems pay for themselves in 3-5 years.

SECURITY WARNING:
Please DO NOT share your OTP, Bank Details, or Passwords with anyone claiming to be from our team. This tool is free to use. We never ask for payments.

Privacy Policy & Disclaimer

Privacy: We respect user privacy. No data entered in this calculator is stored on our servers. All calculations happen locally on your device.

Disclaimer: The results provided are estimates based on global averages. Actual generation varies based on weather, roof inclination, and equipment quality. Please consult a certified solar engineer before installation.

Note for Students: This tool can be used for educational projects to demonstrate the financial viability of renewable energy.
