Abstract: The present invention relates to methods and systems for identifying PV system and solar irradiance sensor orientation and tilt based on energy production, energy received, simulated energy production, estimated energy received, production skew, and energy received skew. The present invention relates to systems and methods for detecting orientation and tilt of a PV system based on energy production and simulated energy production; for detecting the orientation and tilt of a solar irradiance sensor based on solar irradiance observation and simulated solar irradiance observation; for detecting orientation of a PV system based on energy production and energy production skew; and for detecting orientation of a solar irradiance sensor based on solar irradiance observation and solar irradiance observation skew.

Abstract: A computer processor implemented method of identifying the location of a renewable energy system; providing a set of renewable energy systems having at least two location-known renewable energy systems each having a longitude and latitude pair and production data; providing at least one location-unknown renewable energy system in a computer processor; correlating by a computer processor each location-unknown renewable energy system to at least one location-known renewable energy system according to location-known renewable energy systems longitude and latitude pair and production data; providing a best-fit location for each location-unknown renewable energy system by triangulating the location-unknown renewable energy system to provide a triangulated latitude and longitude; setting the triangulated latitude and longitude for the location-unknown renewable energy system to become a location-known renewable energy system that is part of the set of renewable energy systems.

Abstract: The present invention provides methods and systems to estimate energy losses due to soiling in photovoltaic (PV) systems from data including the measured energy and power produced over the lifetime of the system, the system size and configuration data, the weather conditions (including irradiance, precipitation, ambient and panel temperature, and wind conditions) over the lifetime of the system, and derived meteorological condition information (e.g., the history of clear-sky conditions at the location of the site).

Abstract: The present invention provides methods and systems to estimate energy losses due to partial equipment failure in photovoltaic (PV) systems based on measured power and energy data, weather data, PV system configuration information, and modeled power and energy generation data.

Abstract: The present invention provides methods and systems to estimate energy losses due to shading in PV systems from data including the measured energy and power produced over the lifetime of the system, the system size and configuration data, the weather conditions (including irradiance, ambient & panel temperature, and wind conditions) over the lifetime of the system, and derived meteorological condition information (e.g., decomposed irradiance values at any time).

Abstract: A system and method in which information relevant to a Photovoltaic (PV) solar-site specific activity environment is displayed on the display screen of an Augmented Reality (AR) device as part of the surrounding environment, instead of on a separate computing device or an installation manual. The activity environment includes PV solar site-specific survey and feasibility analysis, installation and commissioning, Operation and Maintenance (O&M), and site overhaul/removal activities. Thus, relevant information is available to an installer/technician at their fingertips so that the installer/technician can continue the task they are involved in without losing focus. The AR device may record relevant data during site survey and note important points, accelerate installation and commissioning, make O&M more efficient, and record the complete process for ongoing improvement/management of the site.
