What is a BESS ROI calculator?

A BESS ROI calculator estimates battery storage economics from electricity consumption, peak loads, energy price, PV data and potential peak-shaving savings.

Which data is enough for a first battery storage indication?

For a first indication, country, postal code, annual consumption, electricity price, optional peak load, PV status and contact details are enough. The detailed analysis uses load profile, solar profile and electricity bill.

Battery storage live on Mallorca

BESS ROI calculator for industry, PV and charging infrastructure.

Quickly estimate whether a battery can reduce peaks, use more solar power and lower energy costs. The deal scales from a Pixii cabinet with around 50 kWh at 25-50 kW grid connection, to liquid-cooled Solax systems from 125 kW / 264 kWh, up to Ultimate Partners 20ft BESS containers from 1 MW / 2 MWh to 2 MW / 5 MWh. Summer offer: up to 10% project advantage for qualified fast decision-makers. Financing through us is possible from 2 MW / 5 MWh.

What is calculated?

Peak shaving, PV self-consumption and storage sizing in a first screen.

The quick calculation uses annual consumption, energy price, demand charge, peak load, base load and simple solar parameters. For a bankable design we need the electricity bill, local consumption load profile and solar generation profile.

Where is the site?

Country and postal code are enough for the first regional estimate.

How much electricity is used?

If the peak load is unknown, we estimate it from consumption and industry assumptions.

Is there already a solar system?

Commissioning year and feed-in tariff matter because older tariffs strongly affect storage economics.

Detailed analysis

Upload load profile, solar profile and bill.

For the detailed calculation we need the local consumption load profile, the solar generation profile and a current electricity bill. This allows more accurate storage power, capacity, charging windows and self-consumption design.
