## What is SolarCalc?

SolarCalc is the ultimate professional solar energy calculator and rooftop PV feasibility tool for homeowners, solar contractors, engineers, and renewable energy enthusiasts.

Determine exact solar panel requirements, battery bank storage, financial payback (ROI), and 20-year energy savings based on your local solar irradiance and monthly electricity consumption.

CORE CAPABILITIES:

1. INTELLIGENT PV & BATTERY CALCULATOR
- Calculate optimal solar array size (kW), panel count, and required roof space.
- Accurate annual kWh generation forecasts using regional irradiation and peak sun-hour data.
- Complete financial feasibility: Net installation cost, annual savings, payback timeline (years), Net Present Value (NPV), and Levelized Cost of Energy (LCOE).

2. 20-YEAR COST COMPARISON & ROI
- Interactive financial comparison between staying on the grid versus going solar.
- Lifetime cash-flow projections and cumulative net savings metrics.

3. SMART SYSTEM DIAGNOSTICS & UPGRADE PLANNER
- Input your existing solar modules, inverter capacity, and battery storage.
- Add household appliances and electric vehicle (EV) charging profiles to detect power bottlenecks and receive engineering upgrade recommendations.

4. EXPANDED SOLAR ACADEMY
- Master clean energy engineering: Bifacial modules, TOPCon N-Type technology, LiFePO4 vs. Gel batteries, Hybrid inverters with EPS backup, Micro-inverters, and Surge Protection (SPD).

5. LIVE PRIVACY MODE
- Keep your investment and billing figures confidential during presentations and screen sharing with a single tap.

6. PROFESSIONAL PDF PROPOSALS
- Generate client-ready B2B solar feasibility reports with custom company branding and detailed technical specs.

7. EV & SOLAR INTEGRATION
- Calculate solar energy needed to charge your electric vehicle and maximize fuel savings.

Make confident, profitable solar investments today with SolarCalc!
