Energy storage for solar power from Sonnenexpert
Expand your PV system with efficient energy storage
As a specialized Solar company we recommend that you use your powerful PV system with one Energy storage for solar power to complete. This will help you gain more independence and get even more out of your solar power. We also offer large, efficient energy storage systems for Solar parks and Roof systems as well as solar technology and energy storage for private householdsOur experts from sun expert We would be happy to advise you on the possibilities of a photovoltaic system with storage for the inexpensive solar power generated.
That’s why energy storage is needed for solar systems
As part of the energy transition in Germany, around 2035 to 55 percent of our electricity should come from renewable energies by 60 and around 2050 percent by 80. Wind energy and photovoltaics, which feed in fluctuatingly, will make up the main shares.
In view of the growing share of fluctuating renewable energies, the electricity system must become more flexible so that system and supply security can continue to be guaranteed. Energy storage represents one of several options to increase the flexibility of the energy supply. In this way, electricity storage can ensure a balance between generation and consumption. For example, when there is a lot of wind or sun, they can absorb electricity that they can feed into the grid when the weather is calm and the sky is overcast. They therefore offer the possibility of decoupling generation and consumption in terms of time. In addition, electricity storage can also provide so-called control power and thus help to keep the grid frequency stable.
Why energy storage for solar power makes sense!
An energy storage system makes your solar system really efficient, whether with a Solar park or by private household with your own home. Without storage, you primarily only use electricity when the sun is shining – excess energy is fed into the grid, while you have to buy electricity from the energy supplier in the evening or at night. With storage, this changes: The solar power produced during the day is temporarily stored and is available to you exactly when you need it – even after sunset. Investment Energy storage is worthwhile because you can use solar power around the clock.
Independence from electricity
With a powerful energy storage system, you become more independent from rising electricity prices and energy suppliers.
Higher self-consumption
Instead of just 30–40%, you can use up to 70–80% of your solar energy yourself, which saves energy costs.
Sustainability for the environment
The more of your own solar power you use, the smaller your carbon footprint becomes.
Comfort & Security
With modern storage systems, you can control your energy intelligently and sometimes even use emergency power options.
Find the right storage system at Sonnenexpert
Anyone for a Photovoltaic system If you decide to use solar energy, you can't avoid an energy storage system. The basic idea is quite simple: available but not yet needed energy is fed into the grid. First and foremost, solar energy is highly dependent on the weather. What happens if it rains or the sun is overcast? The energy storage system then converts the stored resources into electricity. This makes you much more independent and can save you a lot of money.
Storage systems are available in a wide variety of sizes and configurations, always tailored to the needs and size of your photovoltaic system. The key to choosing the right energy storage system is to determine your needs based on your selection criteria.
Our checklist will help you find the right energy storage solution.
