Helios Solar Monitor

Plan and forecast your solar output — production estimates, ROI, weather risk, shading & reports. No hardware needed. Try Premium free for 7 days.

Helios Solar Monitor is a hardware-free solar planner and forecaster. Add any installation by its location and panel setup, and get accurate, physics-based production estimates — no inverter or smart device required.

NOTE: All figures are estimates computed from live weather + your panel configuration (clearly labeled "estimated"). Helios Solar Monitor is a planning and forecasting tool, not a real-time inverter monitor.

PLAN & FORECAST • Estimated live power (kW) and today's production (kWh), driven by sun position • Multi-day production forecast • Accurate solar geometry (Equation of Time, longitude & DST corrected) • A dynamic hero that shifts with the sun through the day

FLEET, NOT JUST ONE PANEL • Manage multiple installations in one place • Per-installation tilt, azimuth, panel type, inverter limit and horizon shading • Interactive home-screen widget

PROFESSIONAL ANALYSIS (Premium) • Financial analysis — ROI, IRR, NPV, LCOE, discounted payback • Agricultural / irrigation calculator (FAO-56 ET₀, crop coefficients, pump sizing) • PDF & CSV reports — daily, weekly, monthly • PVWatts-style loss breakdown (cloud, temperature, soiling, system, clipping, shading) • Environmental risk — dust/soiling, hail and wind • Historical analytics & trends • Weather hazard notifications

DATA FROM EVERYWHERE Open-Meteo, NASA POWER, PVGIS and air-quality data combine for location-specific estimates.
