Energy storage

– We can store our surpluses with the energy operator through the prosumer program, but it is worth remembering that the surpluses that will return to us will be collected after taking into account the storage fee.
– The second way is to store energy in batteries, accumulators and even in our electric cars.

The storage process involves storing electricity from an available source, which can be converted into electricity if necessary.

An energy storage facility is a separate device or set of devices used to store energy in any form, without causing emissions that constitute a burden on the environment, in a way that allows for at least partial energy recovery.

It is possible to receive funding from the Moje Prąd 4.0 program in the amount of up to PLN 16,000.

The energy storage works like a battery, which means that it collects energy up to its specific capacity and protects us against the effects of power failure.

A lot depends on the manufacturer we choose, the average value we can assume is 25 years.

It is worth choosing an appropriate energy storage facility that will meet our needs in the event of a power failure. It is standardly assumed that for a 3 kWp installation we select a storage unit with a capacity of 3 kWh.

The very rapid development of renewable energy sources means there is not enough time to expand the energy network, which is a problem for our energy operators. The lack of such stabilization in the long term will result in increased requirements for prosumer consumption and the use of energy storage facilities.

If power failures occur frequently in your business and it is necessary for you to generate income, then it is worth protecting yourself against such an eventuality. This will allow you to maintain the continuity of your income generation, and you can include the energy storage itself in your business costs, which is completely different from including “possible losses” during a power outage.

Because our photovoltaic installation, when generating excess energy through panels that we cannot currently use, will charge our energy storage, and when there is no production of the appropriate amount of electricity that we want to use, we will then use the energy we store in our storage. This entire process means that the battery works cyclically, charging and releasing energy alternately, which is why we recommend gel batteries, which are well adapted to this mode of operation and will not lose their efficiency too quickly.

It depends on your car consumption, the power of your photovoltaic installation and the capacity of the battery you have installed. All surpluses that are currently generated go straight to the battery, which means it depends, but it should not exceed a few hours.

When our energy storage is already full and we still produce surplus electricity, it is worth using this moment and charging our electric car to full capacity, this will relieve the load on the transmission network and not send our electricity to the power grid, for which we will later have to pay on the way back. pay.

A lot depends on what type of installation you have and what your budget is. However, it is worth assuming that for a 5 kW installation you need at least a 5 kW battery, which means that the cost of such a battery is between EUR 2,000 and EUR 4,000 without installation and additional equipment.

If the energy storage is an addition to an existing photovoltaic installation, most often such a battery will be installed near the inverter.

Of course, contact us and let’s talk about everything together.

Switching the inverter’s operating mode takes only a few seconds, which means that after a while we will be using our own energy reserves.

The energy storage will not change our status, we will still have the status of a prosumer.

Not all energy storage systems
