PV Predict smoothing the wrinkles in the distributed generation electrical grid

About Us

PVPredict develops machine learning algorithms for advanced statistical performance monitoring and PV generation forecasting. Six years in development with support from the Israeli ministry of energy has led to a SaaS product now available to monitoring companies to enable their customers to effectively ascertain the health of their systems every day while enabling grid managers to reclaim control of the grid flow.

Target customers:

  • Energy traders with PV in their portfolio
  • Transmission system operators
  • Distribution system operators
  • PV monitoring companies
  • PV fleet owners
  • Inverter manufacturers

The Challenge

Over half of the installed PV power in most countries is installed on rooftops and managed by residential or commercial customers. These systems lack good performance monitoring due to the cost of hardware and software. These customers are not aware of their system’s availability beyond the receipt of their monthly electrical bill. Yet they aggregate into large virtual PV power plants that feed the national grid as an unknown variable to the grid manager. So the system owner has no idea how his system is performing from an objective point of view, if at all and the entities managing the grid at both the national and local level are dealing with rogue power plants they cannot take into account in the delicate undertaking of electrical grid management.

The Solution

A Statistical Performance Monitoring System that requires:

  • No hardware
  • No input of system configuration
  • No analysis software

Requiring only: Inverter or generation meter output & GIS location Benefactors of our system include:

  • Owners of small, medium even large PV systems
  • PV monitoring companies
  • PV fleet owners
  • Inverter manufacturers
  • Energy traders including PV in their portfolios
  • Transmission System Operators (TSO)
  • Distribution System Operators (DSO)


PVPredict has developed machine learning algorithms that predict the next day’s hourly generation of any solar PV inverter without the use of sensors or knowledge of the system configuration. The algorithms also show promise in predicting failures before power loss occurs. These algorithms are the core technology for the following services:

  • PV System Performance Monitoring
  • Day ahead and Hour ahead energy trading
  • Energy forecasting for Utility reporting and reducing spinning reserve
  • Aggregation for Virtual Power Plant (VPP)
  • Validation for green certificate programs
  • Distributed Energy Resource Management System (DERMS)

Strategic Partners

InfoPV is the home of the SolarEra.net backed program for our Distributed Energy Resource Management System (DERMS) pilot project designed to enable a DSO to manage the voltage in residential distribution grids with a high level of solar PV penetration while aggregating the neighborhood into a virtual PV plant for reducing spinning reserve.

Israel’s Ministry of Energy is a long time supporter and has provided three rounds of investment in PVpredict.

A member of the IEA PVPS-Task 13 since 2010, we have collaborated with PV experts from over 25 countries. our development can be found described in the 2017 report “Improving Efficiency of PV Systems Using Statistical Performance Monitoring”.

DecisionMakers ltd. is the company owned and managed by Dr. Eyal Brill in which the machine learning algorithms driving PVPredict where developed.

Owned and managed by Mike Green is the vehicle that drove the first 5 years of Pvpredict development opposite the world solar PV market.
