Sustainability and ESG criteria are also very popular with companies. A Commercial solar system with storage tank is becoming increasingly important. Companies are looking for efficient ways to cover their energy requirements, cut costs and reduce their ecological footprint. A commercial solar system with Large-scale battery storage can be a sensible investment for companies that want to become less dependent on electricity suppliers and reduce their peak loads.
Why does a solar thermal system with storage make sense?
In a photovoltaic system, solar energy is converted into electricity, which is then ideally consumed directly in the business. It is also possible to feed it into the public grid. However, PV electricity production is rarely absolutely identical to the load profile of a business. When the sun is low or the weather is bad, for example, less PV energy is generated. At weekends or in summer in the early morning or late evening hours, on the other hand, solar systems also produce cheap electricity. This usually remains unused by the operating companies. A storage system makes it possible to store this electricity and call it up when needed. This reduces the need to purchase expensive grid electricity and lowers thus the electricity costs considerably. A commercial solar system with storage is therefore particularly interesting for companies with high energy requirements, such as production and industrial companies. However, smaller companies can also benefit from such a system if they want to increase their energy efficiency.
Advantages of a solar system with storage tank
An important advantage of a solar system with storage is therefore the ability to use the self-produced electricity even when the sun is not shining. Thanks to the storage system, the surplus electricity can be stored during the day and used later in the evening or at night.
However, it also opens up the possibility of controlling the time at which energy is supplied to the grid. This means that companies can sell electricity at times when electricity prices are at their highest. This generates additional income. The flexibility to use or sell the electricity, depending on the current demand and price situation, optimizes the profitability of the system.
Overall, companies are so More independent of electricity suppliers. They therefore also increase their Security of supply, as the stored electricity can be used as a backup source in emergencies or during power outages. The ability to maintain operations can offer significant financial benefits. In addition, by using battery storage, companies can optimize their Significantly reduce grid fees. These currently amount to around 25 % of total electricity costs.
Through an intelligent Energy management system the use of stored solar energy can be deployed in such a way that short and expensive load peaks avoided become. Finally, commercial solar systems with storage also contribute to Reduction of the CO₂ footprint of a company. By using clean, self-generated solar power, the need for fossil fuels and conventional grid electricity is reduced. This not only promotes environmental friendliness, but also demonstrates a strong commitment to the environment, which is reflected in positively on the Image of the company can have an effect.
Disadvantages of electricity storage systems
A commercial solar system with storage can have a lot of advantages, such as reducing electricity bills and improving the environmental footprint. However, there are also some disadvantages that need to be considered when deciding on such a system. One of the biggest disadvantages is the still relatively High purchase price the memory itself. Of course, this depends primarily on the storage capacity. Larger capacities generally mean higher costs.
Another factor is the technology used. There are lithium-ion, lead-acid, nickel-cadmium, etc. Lithium-ion batteries are currently the most common on the market and offer a good balance between performance, service life and cost. Installation can also be costly if additional rooms, additional components, inverters or monitoring systems are required. The additional costs for storage systems are therefore individual and can often range from several thousand to several hundred thousand euros or more, depending on the size and specific requirements of the company. For example, if only expensive peak loads are to be reduced, batteries with a lower storage capacity may be sufficient. It is also possible to integrate charging stations with energy storage systems or the company's e-fleet through the Vehicle to Grid (V2G) technology, which is not yet fully mature.
In Germany, there are numerous storage technologies in particular. Support programs and Tax concessionswhich can reduce the purchase price immensely. So before a company invests in an electricity storage system, it is advisable, Professional advice from experts to determine the right size and technology for the company's specific requirements and to assess the financial viability of the investment.
Conclusion: Why investing in a solar thermal system with storage is worthwhile
In conclusion, it can be said that investing in a commercial solar thermal system with storage can be a worthwhile decision. The advantages are obvious: by using renewable energy sources, companies can reduce their CO₂ emissions and thus make an important contribution to climate protection. At the same time, they can reduce their energy costs in the long term and become less dependent on rising electricity prices. The possibility of feeding surplus energy into the grid and receiving remuneration for it is also a major plus point. Of course, there are also disadvantages, such as the high purchase costs and possible restrictions on the choice of location. But overall, the advantages outweigh the disadvantages for many companies and it is worth taking a closer look at the topic. Financing options such as leasing or loans can help to cover the costs. In summary, it can be said that commercial solar systems with storage are a forward-looking investment that makes both economic and ecological sense.
