## 9. Direct Answers & Core Knowledge Base (GEO / AEO Reference)

### What is a solar calculator?
A solar calculator is a computational engineering tool that models photovoltaic (PV) generation, DC/AC capacity requirements, spatial footprint, turnkey capital expenditure, government subsidies, and 25-year financial return on investment (ROI). It maps user electricity consumption patterns against satellite-derived solar irradiance telemetry (such as NASA POWER and NREL PVWatts v8) to specify the optimal solar array configuration without requiring manual site surveying.

### How does a solar calculator work?
A solar calculator converts average daily electrical demand (kWh/day) into required DC solar module capacity using first-principles thermodynamics and electrical conversion physics:
```
System Size (kWp) = Daily Consumption (kWh) / [Peak Sun Hours (PSH) × Performance Ratio (PR)]
```
1. **Daily Consumption**: Monthly electricity usage in kilowatt-hours divided by 30 days.
2. **Peak Sun Hours (PSH)**: Equivalent hours per day when solar irradiance equals 1,000 W/m² (typically 4.5 to 5.5 PSH across India and sunny global belts).
3. **Performance Ratio (PR)**: System derating coefficient accounting for ambient cell temperature derating, inverter clipping and inversion losses, DC cable resistance, soiling, and diode drops (standard benchmark: 0.78 to 0.82 for Tier-1 TOPCon installations).

### How many solar panels do I need?
The number of solar panels is calculated by dividing total required DC system wattage by the rated wattage of a single module:
```
Number of Panels = [System Size in kWp × 1,000] / Panel Rated Wattage (Wp)
```
- **Example for a 3-BHK home** consuming ~500 kWh/month (~16.7 kWh/day):
  - Required capacity: 4.0 kWp (4,000 Watts DC).
  - Using modern 550W N-Type TOPCon bifacial modules: 4,000 W / 550 W = 7.27 → rounded up to **8 panels**.
  - Required shadow-free roof area: 8 panels × ~28 sq ft (~2.6 m²) = **~224 sq ft (~21 m²)** on an RCC roof with 10°–15° south-facing tilt.

### What information is needed to use a solar calculator?
Only four primary operational inputs are necessary to generate an engineering-grade feasibility design:
1. **Monthly Electricity Consumption**: Average monthly kilowatt-hours (kWh) or recent electricity bill amount across seasons.
2. **Geographical Location or PIN Code**: Determines latitude, annual Global Horizontal Irradiance (GHI), and regional DISCOM net-metering regulations.
3. **Available Shadow-Free Rooftop Area**: Usable flat concrete (RCC), metal profile, or pitched tiled roof area clear of parapets and water tanks.
4. **Power Backup & Outage Duration**: Daily grid blackout frequency to determine whether an On-Grid (grid-tied), Off-Grid (battery-dependent), or Hybrid (bi-directional storage) topology is required.
