SolarForge: PV Installer Kit

SolarForge is a pro toolkit for solar installers, PV engineers and advanced DIYers — field sensors, engineering calculators and client project files in one offline app. No login, no internet required: everything runs on your phone, right on the roof or in the truck. Stop juggling spreadsheets, a compass app and three different calculators. SolarForge brings sizing, layout, electrical and financial tools together, then saves any result to a client project and exports a branded PDF estimate. FIELD TOOLS (USE YOUR PHONE'S SENSORS) - Solar Compass — true heading with magnetic-declination correction and target-azimuth lock - Tilt / Inclinometer — live panel tilt plus optimal seasonal angles - Sun Path — today's solar arc, sun position, sunrise, sunset and solar noon (NOAA algorithm) - Shading Profiler — capture obstruction azimuth and elevation to estimate solar access SYSTEM DESIGN - Energy Yield — annual and monthly kWh from system size, latitude, tilt, azimuth, shading and soiling - Panel Layout — fit panels onto a roof area with a live diagram ELECTRICAL CALCULATORS - String Sizing — modules per string from cold Voc and hot Vmp limits - Wire & Voltage Drop — recommended copper AWG meeting voltage-drop and ampacity targets - Battery Sizing — off-grid bank Ah for LiFePO4, AGM or flooded - Inverter Sizing — recommended AC size with DC:AC ratio and clipping risk - OCPD / Breaker — over-current device sizing (Electrical tools reference common code limits such as NEC 690.8 and 240.6.) FINANCIAL - ROI & Payback — payback period, lifetime savings, ROI and LCOE CLIENT PROJECTS - Save any calculation to a client project - Export a clean, branded PDF estimate to share with the customer REFERENCE & SETTINGS - Built-in tables: copper conductors, battery chemistry and peak-sun-hours - Metric or imperial units, your currency, and dark or light theme WHY INSTALLERS CHOOSE SOLARFORGE - Offline-first — works with no signal on site - Private — your project data stays on your device - Fast — answers in seconds, no spreadsheets - Built on transparent, tested engineering calculations IMPORTANT SolarForge produces field estimates to speed up your work. Always verify against manufacturer datasheets, current electrical code and your authority having jurisdiction (AHJ) before finalizing any design.
