Solar Energy System for Commercial Buildings

Benefits of Commercial Solar Systems

The commercial solar energy storage system is a catalyst for the green energy transformation of modern commercial buildings, and the system's technical advantages substantiate the system's efficiency in energy utilization. Central to the system is the combination of photovoltaic inverters and energy storage batteries, with intelligent MPPT (Maximum Power Point Tracking) technology integrated into the inverter to optimize solar energy capture, with conversion efficiency remaining at a leading level in the industry. The energy storage component uses lithium iron phosphate (LiFePO4) core cells, coupled with the liquid cooling energy storage cabinet technology, and integrated intelligent Electro-Mechanic System (EMS) management system, to provide efficient energy storage and reliable power supply. The core battery's cycle life is greater than 8000 cycles and multiple protective safety mechanisms are installed to eliminate risks related to overcharging and short circuiting, operating in the high energy conditions typical of commercial buildings, including shopping malls and office buildings, for extended periods and at high loads.

Investment Reduction for Commercial Energy Costs

For years, the increase in cost to the energy consumers has remained as one of the biggest operational stress for commercial buildings, however, energy storage systems paired with solar energy can fundamentally change this by means of peak valley arbitrage and energy self-sufficiency. Commercial assets consume large amounts of electricity during the peak operational hours, and the system can capture and save any excess electricity produced by the solar panels to be used during the hours of most expensive electricity, significantly decreasing the needed purchases of electricity to store from the grid. Also, the system has the ability to switch between an on grid and off grid operation to provide and assure uninterrupted supply to the commercial buildings in the occurrence of grid outages and/or power outages. This also avoids the risk of any economic losses from outages. Based on our operational data, commercial buildings can expect an annual energy cost savings of approximately 30%-50%, while the energy storage system typically pays for itself in 5 to 7 years. This also  provides an excellent long-term economic value.Global Certification and Safety Standards

Safety and compliance for solar energy storage systems are top priorities for construction projects for commercial buildings

Global authoritative certifications ensure the quality of the systems. Authentic commercial solar systems are accredited with various international certifications including ISO UL CE and UN38.3. UL1973 certification is the “gold standard” for the North American market. It involves rigorous testing for thermal runaway and electrical insulation. UL-rated products receive recognition from insurance and power grid companies. UL certification is the highly regarded recognition for the thermal runaway protection of insulation systems. ISO certification showcases compliance with quality control to the European Union and CE certification demonstrates quality compliance. Additionally, the certifications guarantee the commercial building's systems will take a long time before operational wear begins and assist in the compliance with energy policies of the countries and regions to help eliminate the suspension of the projects to the non-compliant areas.

The Practical Application of Commercial Solar Energy Storage Systems

The fully integrated commercial solar energy storage systems begin to show their practical value with application examples. For instance, in East China, an integrated solar and storage off-grid system of 50 kW-100 kWh was installed in a comprehensive office building covering an area of over 10,000 square meters. This setup is about to integrate power generation, grid connection, and energy storage. After commencement of operations, the building's green energy self-sufficiency rate is over 40%. This results in an annual electricity cost savings of 200,000 yuan and a more than 300 tons reduction in annual carbon emissions. Furthermore, a large shopping mall in South China has installed a commercial energy storage system located in an all-in-one unit, which addresses the power consumption of lighting, air conditioning, and other equipment in the mall, and also offers an emergency power supply to the mall’s fire protection and surveillance system. This greatly enhances the energy safety of the commercial building. Such examples show that solar energy storage systems can adapt seamlessly to multiple commercial building scenarios.

Sustainability and attainment of ESG goals

In the context of low-carbon growth, operational ESG goals are of primary importance to the businesses that manage commercial buildings, with solar energy storage systems supporting the achievement of these goals the most. The system utilizes clean solar energy to substitute the traditional fossil energy sources used in commercial buildings, thereby significantly lowering the carbon footprint. The green energy produced can be counted towards the business's low-carbon energy utilization, which aids in improving the company's ESG score. Furthermore, the entire life cycle of the system is in alignment with the objectives of the circular economy and the system is produced and transported in eco-friendly packaging and uses recyclable materials, which reduces environmental harmfulness to a greater extent. For commercial building operators, the installation of solar energy storage systems is a dual benefit of providing a green alteration to the energy usage and also a notable positive manifestation of the business which can amplify the brand value of the company significantly in the marketplace.

Manufacturing Support and Supply Chain Management

For commercial solar energy storage systems to smoothly land and operate over the long term, a comprehensive supply chain and professional manufacturing capabilities are needed. The industry has specialized manufacturers with more than 11 years of experience, whose services are provided to more than 171 countries and regions and have more than 190 active business collaborations worldwide. Thanks to his advanced manufacturing technology and professional engineering team, the manufacturer is capable of customizing solar energy storage systems according to the specific area, power needs, and business profile of the commercial building. Other than system design and installation, the manufacturer also provides maintenance and after sales services. The manufacturer has more than 28 active patents and continuously improves the existing systems through research and development, providing guaranteed commercial performance to their installations.
