About this app
Pro installer toolkit: Compass, Tilt, PV Calculator & Quote Builder.
The Professional Solar Installer's Toolkit
Solar Calibrator is the all-in-one pocket utility for PV installers, engineers, and advanced DIYers. Calibrate panel angles with precision, size battery banks, calculate wire gauges, and generate professional PDF quotes—all without internet access.
CORE TOOLS:
☀️ Solar Compass & Tilt: Align panels to True North/South and find the optimal tilt angle for Summer or Winter efficiency. Uses advanced sensor damping for steady, professional readings.
🔋 Battery & Inverter Sizing: Calculate exact off-grid storage needs based on load. Supports Lithium (LiFePO4) and Lead-Acid profiles.
⚡ Wire Gauge Calculator: Prevent voltage drop and fire hazards. Calculates safe wire thickness (AWG/mm²) based on voltage, current, and run length.
📋 Load Audit & Quote Builder: Build a complete appliance load profile and generate instant PDF estimates to share with clients.
📐 PV Array & String Sizing: Determine the maximum number of panels per string based on local temperature lows (Voc limits) to protect your inverter.
🌲 Obstruction Analysis: Calculate shadow cast distance to ensure your array stays shade-free during winter solstice.
NEW IN V2.0:
Field Mode UI: High-contrast Dark Mode for visibility in bright sunlight.
PDF Reports: Export detailed calculation reports and client quotes.
Smart Location: Auto-detects latitude for precise sun-hour estimations.
