Solar Calculator

SolarWeb

Web-based calculator for estimating solar panel output, ROI, and payback period based on location, system size, and tariff rates.

Tools: React, TypeScript, Tailwind CSS
Key Result: Instant solar feasibility estimation

Overview

An interactive web tool that helps users quickly estimate the financial viability of rooftop solar installations. Input your location, roof area, electricity consumption, and tariff rate to get an instant feasibility report.

Planned Features

  • Location-based Solar Resource: Auto-estimate solar irradiance based on Indian geography
  • System Sizing: Recommend optimal panel capacity based on roof area and consumption
  • Financial Projections: 25-year cash flow with NPV, IRR, and payback period
  • Tariff Comparison: Net metering vs. gross metering economics
  • PDF Export: Download a one-page feasibility summary

Current Progress

  • Basic calculation engine implemented
  • Working on location API integration for solar resource data
  • UI design for input forms and result visualization in progress
