With battery
We assess whether storage offers a real benefit for your installation, with a clear comparison of costs, usage and technical options.
With or without a battery
The battery shifts some of your production to hours when the sun isn’t shining. We compare the additional cost with the energy you can actually use.
| What we compare | Without a battery | With battery |
|---|---|---|
| Production use | Instantly, while your appliances are running. | Power now and later with stored energy. |
| Surplus energy | Exported to the grid in accordance with the agreement. | Stored up to the available capacity; the remainder is exported. |
| Initial cost | Solar panels, inverters, and installation. | A battery, a suitable inverter, and related work are added. |
| Losses and lifespan | Inverter conversion losses. | Additional charging losses and gradual capacity reduction. |
| Power outage | Not provided automatically. | Requires suitable backup equipment and special wiring. |
| When is it worth considering | When consumption coincides with production. | When you have surplus production during the day and need energy later. |
The financial comparison is based on your consumption, using consistent energy price assumptions and full installation costs. A battery does not automatically mean a faster payback.

The options include different equipment. The amounts above are catalog prices; the final quote is confirmed after the property assessment and site visit. Lower cost or adding a battery does not, by itself, determine the financial return.
Your needs come first
The right choice is based on specific details. The assessment explains what we recommend and why, along with the assumptions behind the financial scenario.
In practice
Athens. We installed a 10.6kW photovoltaic system, making use of flat roof on a home. See the equipment and installation details.

The final price depends on the equipment, the site and the work involved. Ask for the same breakdown for every option.
Panels, inverter, mounting structures and storage, where selected.
Installation, electrical work, assessment and connection process.
Production, self-consumption, energy prices and operating costs, based on stated assumptions.
We’re here for you
We start with your property and energy consumption.
