Maximize Your Independence with Solar and Energy Storage System

If your solar system produces more electricity than you currently need, your can use a electricity storage to use it for a later time. This way you can use electricity around the clock and not only when the sun is shining. With the 1KOMMA5° energy manager Heartbeat you can optimise your power consumption and increase your independence from the grid.


6 Reasons to Enhance Your Solar System with an Energy Storage Unit

1. Energy Cost Savings

By storing excess energy, you can use it when energy prices are higher, which helps to lower your energy bills and increase your cost savings.

2. Enhanced Energy Independence

An energy storage unit allows you to store excess solar energy for use during times when the sun is not shining. This helps to reduce the amount of energy that you need to purchase from the grid and increases the overall efficiency of your solar system.

3. Enhanced Sustainability

By reducing your dependence on the grid and utilizing renewable energy, you can help to reduce your carbon footprint and contribute to a more sustainable future.

4. Increased Solar Panel Performance

By storing excess energy, you can optimize the performance of your solar panels, increasing their overall efficiency and helping to lower your energy costs.

5. Load Shifting

Energy storage units can be used to shift energy consumption to off-peak hours when energy prices are lower, reducing energy costs and increasing energy efficiency. Furthermore, it can ensure that power outages or natural disasters do not disrupt the energy supply. Ensuring improved resilience.

6. Increased Property Value

Installing an energy storage unit can increase the value of your property and make it more appealing to potential buyers.

We decided to go solar for several reasons: for ecological reasons, for political reasons, to be more independent and to please our children.
Zilian Family
I already knew the Göttingen location before it became part of the 1KOMMA5° Group. The team from Göttingen then informed and advised us, so that we decided on a solar system from 1KOMMA5°.
Sybille Fichte
I heard about 1KOMMA5° through a neighbour and in fact another neighbour has now also opted for 1KOMMA5° as a result of the installation at my house.
Dr. Josef Frasunek
We wanted to become more independent. Also from the electricity market. We asked various suppliers and 1KOMMA5° was able to deliver the fastest.
Mecke Family
That was an investment in the future! I want to produce free electricity on my own roof.
Guido Kahlmeyer
I would recommend my friends to think about environmental protection: What can I do personally? For example, buy a photovoltaic system. That way I'm doing something for the environment.

FAQ Energy Storage

Any Questions?

How does energy storage work with a solar panel system?

Energy storage works with a solar panel system by storing excess energy generated by the solar panels. This stored energy can then be used during times when the sun is not shining or when energy demand is higher. The energy storage system and solar panel system can be easily integrated, allowing you to optimize your energy efficiency and reduce your dependence on the grid

Why is energy storage important?

Energy storage is important because it helps to increase the overall efficiency of renewable energy systems. By storing excess energy, you can reduce your dependence on the grid and increase your energy independence. Energy storage also helps to reduce energy costs by allowing you to use stored energy during times of peak demand when energy prices are higher.
