Atar by Getatar — solar system & solar panel design platform
Atar is the platform from Getatar that designs, sizes, and optimizes solar systems — from selecting the right solar panel to building a complete OnGrid, OffGrid, hybrid, or telecom installation. Estimate production, choose equipment, and run engineering-grade calculations in one place.
Our mission
To make solar system design accessible and accurate for engineers, installers, and project owners. From choosing the right solar panel by nominal power (Wp), efficiency, and temperature coefficient, to sizing a full PV plant, a telecom site, or a hybrid system, the Atar platform — built by Getatar — helps you choose the right components and understand expected yields with clear, auditable results.
What we stand for
Our values shape the product and the experience we offer.
Panel-first design
We put the solar panel at the center of every design — alongside inverters, batteries, charge controllers, and cables — with engineering-grade tools built for real projects.
Accurate PV calculations
Atar produces sizing and production estimates based on your exact location, the solar panels you choose, and monthly, daily, or hourly resolution — no rules of thumb.
Clean energy, simplified
Getatar designs Atar to help everyone — from solo installers to engineering teams — deploy more solar capacity and maximize renewable energy use.
Transparent & reliable
Clear assumptions, traceable data sources, and notes so you know how every number — from solar panel output to financial ROI — is derived.
What you can do on the Atar platform
Register your solar panels, inverters, batteries, charge controllers, and cables; run sizing and production calculations for OnGrid, OffGrid, telecom, and hybrid systems; and view every result in one place — all backed by Getatar's engineering models.
