Soltell’s SysMap API V1.1 delivers Sensorless technology-powered, Orange Button-compliant solar performance data, designed for Energy Finance, SCADA & EMS platforms. One REST integration gives you real-time/historical production, modeled energy, availability, performance indexes, soiling losses, predictive O&M insights in any language, and full operating reports.

Rooftop solar PV systems are tightly coupled to the stability of the electricity grid. While most discussions focus on modules, soiling, shading, or inverter efficiency, one of the most influential factors on real-world performance is the condition of the local grid. Voltage, phase quality and even frequency determine whether a solar inverter can operate continuously or must disconnect for safety.

Discover accurate solar PV measurement with Sensorless technology accuracy level of 94-98%. Gain solar insights from 13,000 monthly system measurements to optimize performance.

Explore why SysMap Performance Analytics is a game-changer in rooftop solar analytics, delivering advanced insights to optimize Energy Management Systems (EMS) and enhance solar business profitability.

Availability is a critical metric that measures the ability of an energy system to deliver its intended function when required.

Security-related disruptions in the operation of photovoltaic (PV) systems are a concern in today's interconnected world.

Soltell's Sensorless technology makes it possible to accurately quantify the dust and dirt upon solar system panels in almost real-time.

Solar inverter overload and derating, including options for detecting those chronic issues on time.

In line with solar Performance Ratio and the modeled Expected Yield performance indicators, one should also consider Availability indicators

The issue of leakage in photovoltaic energy systems is controversial and you will find a large number of professional opinions on the subject. Some recommend completely ignoring the matter, while others do recommend monitoring the phenomenon and executing a systemic solution once every few years, and there are those who recommend treating the phenomenon as soon as possible - allocating the problematic component with the defective insulation. Who is right? Well - probably all
