Battery energy storage
Generate electricity in the sun, store it, and use it when you need it!
Battery energy storage helps you to have “free” electricity that you can use at any time. While it was previously possible to conclude a so-called annual settlement contract with the electricity supplier, currently the only way to avoid losing the electricity that is produced but not consumed is to store it on site.
Save on your electricity bill with us, plus reduce it to a fraction, or even eliminate your gas bill!
The calculation below – which does not qualify as an offer – presents the energy modernization package for an average-sized family house heated with a traditional gas boiler. (To prepare a specific offer, a lot of precise information is needed, including the exact data of the property, its sunlight, actual consumption data and user habits and needs. Contact us, our colleagues are at your disposal and will prepare an accurate calculation tailored to your house for you)
Package contents:
– solar panels
– inverter
– battery pack
– heat pump (with heating/cooling function)
(Important: the recommended heat pump can not only replace gas boiler heating, it is also suitable for providing domestic hot water and summer cooling for the entire house. To take advantage of these functions, a so-called HMV (domestic hot water) tank and fan-coil units must be installed. This expansion can be done at any time afterwards)
Initial data
House floor area:
120 m2
Heating type:
radiator heat emitters, with a traditional gas boiler
Annual heating gas consumption:
2.200 m3
Annual hot water production and cooking gas consumption:
530 m3
One-time investment fee
Total equipment requirement for energy modernization (6 kWp solar panel; 6 kW inverter; 12 kWh battery pack; 15 kW heat pump):
5.250.000 Ft + VAT
Installation and commissioning fees:
2.300.000 Ft + VAT
The total net cost, as above, is approx.
7.550.000 Ft + VAT
Overhead expenses that can be saved with the investment:
By using only the heating function of the heat pump system, the price of the entire amount of gas previously used for heating can be saved! The recommended, modern heat pump has a high “degree of goodness, efficiency”, the COP value is ~ 4, which means that it produces 4 units of heat energy from 1 unit of electrical energy, so it operates with very favorable electricity consumption. If we add to this the “free” electricity generated by solar panels and stored in batteries until the time of actual use, then heating your house becomes extremely economical and significantly more affordable than before.
Annual reduction in utility costs available in the example house
Annual gas consumption (full heating) induced by the heat pump:
2.200 m3
872.000 Ft*
Annual electricity consumption of the heat pump that is NOT covered by the solar system**:
Annual energy savings:
782.000 Ft
*of the annual 1,729 m 3 of gas with reduced utility costs (110 HUF/m 3 ) ~530 m 3 goes to the production of domestic hot water, so approximately 800 m 3 is calculated at the non-utility protected price (740 HUF/m 3 )
** basically the months of December and January
The amount saved can be increased even further by installing the already mentioned DHW tank, since then you don’t even have to pay for the gas required to produce hot water.
What do we offer our customers?
- We assess your property, size it, and design the system to be installed.
- In the case of building a new property, we can get involved during the planning stage to avoid costs associated with subsequent modifications and dismantling.
- We fully build, commission the system, and teach you how to use it.
- We provide you with assistance if you wish to cover the investment/part of it with a tender.
- We undertake the maintenance of the system and any necessary repairs.
Advantages:
Increased energy independence.
Energy produced during the day is also available in the evening or on cloudy days. Reduce your network exposure and enjoy a more stable overhead structure.
Comfort without compromises.
Heating (including cooling and domestic hot water supply) solved in one system, even with room-by-room control, modern technology, and high efficiency.
Comprehensive professional background.
Design, permitting, construction, and commissioning – everything in one hand, with many years of experience and systemic thinking.
Safe operation
You do not have to worry about a life-threatening gas or combustion product leak due to a malfunction. The heat pump we recommend is designed (monoblock) and operates outside the house, with only the heat-dissipating units (radiator, underfloor heating, fan-coil, etc.) placed inside.
Cost-effective operation
The high coefficient of performance of the heat pump (COP ~ 4) guarantees efficient heat energy production, i.e. cheaper heating and cooling, cheaper hot water.
