What is Consolectiv ?

Consolectiv is LuciSun’s simulation engine for time-resolved analysis of prosumer energy flows, self-consumption and collective self-consumption schemes, self-sufficiency levels, and energy communities.



It is used to analyse how photovoltaic generation interacts with consumption at the level of individual prosumers and groups of actors sharing energy locally.



The model operates at high temporal resolution and supports the evaluation of energy flows, imports, exports, and local use under different configurations.


Consolectiv is used internally by LuciSun in consultancy activities and is designed for integration into digital tools, feasibility platforms, Excel workflows, and white labelled applications.

Consolectiv is ideal for:

  • Installers and EPCs performing rapid feasibility studies
  • Advisors and engineers evaluating prosumer and community energy configurations
  • Municipal or cooperative energy communities
  • Owners or operators of small commercial buildings
  • Organisations seeking to embed energy flow simulation into their own platforms

Core Purpose

For Prosumers

Analyse how a PV system interacts with household and small commercial electricity consumption, quantify self-consumption and savings, assess system sizing options, and evaluate the impact of behind-the-meter (BTM) battery storage.

For Energy Communities

Assess the impact of grouping multiple consumers and producers, quantify energy exchanges within the community, and evaluate how shared PV generation affects individual participants.

1. Prosumer Simulation Engine

This module supports feasibility studies for residential and small commercial PV systems by simulating the interaction between photovoltaic generation, electricity consumption, and behind-the-meter storage.

It is used to analyse energy flows, self-consumption, self-sufficiency, and the impact of different system configurations under time-resolved conditions.

Consolectiv models:

  • PV generation based on system geometry and nominal power
  • Electricity consumption using synthetic or user-defined load profiles
  • Time-resolved imports, exports, and local energy use
  • Self-consumption and self-sufficiency indicators
  • Evaluation of PV system sizing options
  • Behind-the-meter battery operation and control strategies
  • Financial indicators derived from simulated energy flows

The model enables consistent quantification of energy flows and savings for individual prosumers.

2. Collective Self-Consumption & Energy Communities

This module supports the analysis of collective self-consumption schemes and energy communities involving multiple consumers and producers sharing photovoltaic generation. It is used to evaluate energy flows, sharing mechanisms, and participant-level outcomes in configurations such as co-owned PV systems, cooperatives, and local energy initiatives.

The tool can simulate:

  • Multiple consumers with distinct electricity load profiles
  • Multiple PV systems contributing to a shared generation pool
  • Allocation of shared PV generation among participants
  • Energy flows at both community and individual participant level
  • Aggregated community-level indicators
  • Individual participant performance indicators
  • Daily, monthly, and seasonal dynamics

3. Battery Modelling (Behind-the-Meter)

This module supports the simulation of behind-the-meter battery storage in combination with photovoltaic generation and local electricity consumption. It is used to analyse how battery operation influences energy flows, self-consumption, imports and exports, and system performance under time-resolved conditions for individual prosumers and small commercial installations.

Enabling
