Our algorithms are calibrated against NREL System Advisor Model (SAM) and PVWatts v8 specifications for ±2% annual yield accuracy.
Neural networks analyze local irradiance, temperature coefficient, and shading losses to generate a site-specific production profile.
All consumption data is processed client-side or in ephemeral serverless functions. Your energy profile never leaves your device permanently.
We don't just guess. We match your load profile against a verified database of 50,000+ inverter and battery SKU specifications.
Simulate startup surges, inductive loads, and phantom power draw to ensure your inverter is sized for peak, not just average, demand.
Our calculation engine is open for peer review. Engineers can verify the physics behind every watt-hour prediction.
Stop guessing with simple multipliers. Our workflow forces a bottoms-up analysis of your actual energy physics.
Input your monthly bill or list individual appliances. Our engine calculates your daily kWh requirement and peak surge load.
We assess your location's peak sun hours, roof orientation, and grid stability to determine the raw energy potential.
Receive a complete Bill of Materials (BOM) including exact panel count, battery capacity, and inverter sizing.
Get a professional UAE Solar Engineering Feasibility Report with ROI, DEWA compliance, system sizing & payback analysis. Engineering-grade solar audit.
Discover how AI-powered solar calculators are revolutionizing energy audits with real-time data modeling, commercial load analysis, and precision ROI forecasts.
From HVAC systems to water heaters, discover the top energy vampires in your home and how to tame them.
Our calculator doesn't just use averages. It accesses real-time satellite telemetry and trains on local weather patterns to predict your solar yield with 98.4% precision.
Dynamic 3D modeling of horizon obstruction and tree coverage.
algorithmic selection of hardware for lowest Levelized Cost of Energy (LCOE).

We use the same physics calculations as NREL's PVWatts. However, actual production depends on local shading, panel degradation, and soiling. We recommend a conservative 15% system loss factor.
Yes. The physics scale, but commercial projects often have 3-phase power and demand charges. Our 'Advanced' mode (coming v6.0) will handle peak demand shaving.
Hybrid inverters allow for DC-coupled battery storage, which is 5-10% more efficient than AC-coupled retrofit solutions like the Powerwall 2. It also simplifies the BOM.
No. Your data is your own. We do not sell leads to installers unless you explicitly request a quote via our verified partner network (Opt-in only).
