Store your own energy

Transforming our energy system is one of the biggest global challenges of our times. The efficient and economical use of renewable energies is crucial for conserving our environment and the success of our economy. The basis for this is the development of energy storage technology that enables a transition away from a fossil fuel based energy infrastructure. Source: BVES e.v. Bursting with energy into a clean future Humanity is facing the most pressing challenge of our time: climate change and its impacts and implications. It is time to deliver on ambitious climate objectives and significantly reduce CO2 emissions. Action must be taken to radically transform the entire energy system in order to maintain a habitable environment and ensure the competitiveness of our economy in the future. To this end, we need to promote and develop renewables and shift away from fossil fuels and nuclear power. The basis for an independent, reliable and clean supply of energy can only be formed by utilizing cutting-edge energy storage technologies and efficiently generating and using renewables. This basis is vital when it comes to preserving our environment now for ourselves and for generations to come. It is the guiding principle behind the SunStorage energy storage systems.

Store renewable energy intelligently and save money Despite falling feed-in tariffs, solar systems remain an intelligent investment for your bank balance and the environment. Energy prices for private households have continued to rise in recent years. Meanwhile, the cost of generating solar power has declined steadily. As a result, change is underway: from maximising feed-in right through to maximising self-consumption. The innovative energy management of our SunStorage systems makes it possible to reliably store energy from the sun and retrieve it whenever you or your customers require it. Be it during the day, in the evening, at night or just when it s overcast, your customers can take advantage of low-cost solar power at all times, making them independent of price increases from energy utilities. Installing a powerful SunStorage energy storage system makes it possible to significantly increase self-consumption of your solar power. The specially developed SunStorage Sunculator requires only few pieces of basic data to determine the optimal design of the storage system and solar power system. This enables your customers to achieve up to 80 per cent independence from the grid. Reliably store energy from the sun and use it whenever you need it! Offer your customers the chance to experience their own personal energy revolution with SunStorage energy storage systems!

Self-generated energy pays off Reduce your energy bills with SunStorage energy storage systems. Those who generate and use power from renewables are a step ahead when it comes to price. Solar power has been cheaper than household power since 2012 The costs for self-generated solar power are already lower than energy prices from energy utilities for private households in more and more countries. Given the predicted price increases over the coming years, the difference is set to further increase. SunStorage system solutions allow your customers to put an end to the upward spiral in prices and become their own energy supplier. 70 60 Grid parity Price in cents/kwh 50 40 30 20 Cost of generating solar power 10 Household energy price (price per kwh) 0 2000 2005 Grid parity was achieved in Germany in 2012. 2010 2015 2020 Optimise your degree of independence! The self-consumption rate of a conventional grid-connected system is between 15 and 35 per cent. This is because power consumption and generation usually take place at different times. Intelligent SunStorage systems ensure a proper balance and deliver power whenever it is needed. This makes it possible to achieve up to 80 per cent independence from the grid. Spare your customers from future price increases and opt for independence with our efficient and cost-effective SunStorage systems.

This allows your customers to gain independence and yield a return of about 36,907 in 25 years. Upgrading existing systems An upgrade offers additional advantages for customers such as those in Germany who connected a solar power system to the grid in 2011. These customers benefit from the feed-in tariff and an increased level of self-consumption. Total income generated here over a period of 23 years adds up to approximately 42,965. The energy storage system alone generates an added value of around 15,965.
