What is an energy storage system and how does it work?

An energy storage system applied to self-consumption is the key to managing and controlling your generation. It gives you more flexibility, allowing you to store energy during lower consumption periods and consume it at your convenience. The hybridation is a perfect fit for solar energy. As it only works during daylight hours, a storage system allows surplus energy to be stored and then used during the night or according to your consumption needs.

How do you determine the right size of an energy storage system for a company?

At Ekhi, all our projects are tailor-made to meet all the specific needs of our customers. The optimal sizing will depend on multiple factors, including a client's consumption profile, the origin of the energy to be stored (self-consumption or network installation), and the selected load strategy.

What is the lifetime of an energy storage system?

The useful life of batteries is measured in cycles of use (full charge and discharge). Depending on the technical dimensioning and charging strategy, the battery can go through a series of multiple cycles per year. Depending on the type of battery, the system will last approximately the following number of years:
-Lithium Ion battery storage lasts around 8 to 15 years.
-Acid Lead battery storage lasts around 3 to 5 years.
-Nickel Cadmium battery storage lasts around 15 to 20 years.
-Zinc Bromine battery storage lasts around 5 to 10 years.

What are the fiscal and financial benefits of installing an energy storage system?

Installing an energy storage system can help you make the most financially out of your renewable energy solution. Thanks to the NextGenerationEU funds, energy storage has become more commonplace in recent years. At Ekhi, we take care of managing all the tax incentives and subsidies so that our users can increase their profitability.

What are the advantages of an energy storage system for a company?

A storage system offers many advantages, mainly the capabilities of load shifting and peak shaving. Load shifting is a system that stores surplus energy which can be consumed at another time. Peak shaving avoids consumption peaks to avoid creating excess power and receiving penalties. Both charging strategies can coexist together to maximize your energy strategy.

Do you offer a warranty and technical support for the energy storage systems you sell?

Yes, Ekhi assumes maintenance risks and costs of PPA agreements, taking care of everything related to the installation, quality guarantees, and replacement of parts and systems if necessary.

What types of battery are there and which are the more suitable for renewable storage?

There are several battery types available which include Lithium Ion Phosphate batteries, Lead Acid batteries, Nickel Cadmium (Ni-Cd) batteries, and Zinc Bromine (Zn-Br) batteries. Lithium Ion batteries are typically the best choice for renewable energy storage, as they are the safest, most efficient, have faster charging, and require minimal maintenance.
