ENERGY / ON-SITE CONSUMPTION

Solar PV and battery storage

The sun can support everyday work. To understand how, I connect generation with actual consumption: this is where an assessment of solar PV and battery storage begins.

Grants for private individuals and condominiums in the Aosta Valley

Up to 40% of eligible costs, within the caps. Applications open: 16 November 2026 at 10:00.

Requirements and worked example ↗
Building with solar panels

System sizing follows consumption.

We assess when electricity is drawn from the grid, the space available and plans for growth. Expected generation, on-site consumption and exports are distinct factors: considering them together makes financial scenarios easier to understand.

01

Solar PV system

Analysis of demand, available surfaces and integration with the electrical installation.

02

Battery storage

Assessment of how much energy needs to be shifted over time, power requirements and operating conditions.

03

Existing systems

Compare generation and consumption to identify opportunities for integration or expansion.

Battery storage needs a case-by-case assessment.

An existing PV system is a starting point. Assessing a battery also requires the energy actually available, expected cycles, efficiency, investment and the client’s objectives. Reducing peaks also requires an analysis of load duration and frequency.

When to generate, use or store energy

A battery is one part of a system. Before selecting a BESS, we also consider shifting loads, vehicle charging schedules and new electrical uses in the building. We assess energy to be stored, power and peak duration to compare options on a consistent basis. If the project includes flexibility markets, eligibility and the parties involved require a separate assessment; potential revenue is considered separately from self-consumption benefits.

Useful data

  • Grid import and generation profiles measured over the same time intervals.
  • Characteristics of existing systems and connections.
  • Expected new loads: production, heating or charging.
