"Large solar projects from a single source": Solarwatt expands product portfolio with commercial storage solutions

Solarwatt is now offering storage solutions for commercial and industrial applications, opening up additional sources of income for installation companies. The solar company, which operates throughout Europe, launched a new high-performance product portfolio for homeowners last year. Solarwatt has also been developing customised energy solutions for the commercial sector for many years - from planning and component selection to commissioning: "With the new commercial storage systems and the matching inverters in an all-in-one system, we are rounding off our portfolio in the commercial sector. We are now in a position to offer large solar projects with batteries from a single source," explains Solarwatt CPO Peter Bachmann.

Market for commercial storage systems continues to grow

The market for commercial storage systems is currently experiencing strong growth. "The number of companies that rely on their own solar system with battery storage continues to rise. This is because it enables companies to massively reduce their energy costs. On average, a commercial solar system with battery storage pays for itself after around seven years," emphasises Peter Bachmann.

According to Peter Bachmann, the efficiency of a commercial solar system with battery storage is further increased by the opportunities offered by the new energy market: "By using a dynamic electricity tariff in combination with a battery storage system, companies can draw energy from the electricity grid when prices on the electricity exchange are particularly low. The cheap energy is stored temporarily in the battery storage system and can then be used when the price on the electricity exchange rises again. This can save companies several thousand euros in energy costs - every year."

Regional support and simple installation

In a careful selection process, Solarwatt are working with a Europe-wide partner for commercial & industrial batteries: "In addition to the efficiency of the devices, the coherent safety concept and more than 10 years of experience in the commercial sector, we were also impressed by the strong regional support, which Solarwatt customers will also be able to benefit from in the future. This includes assistance with installation and free initial commissioning," says Peter Bachmann. The commercial storage systems are available in both AC and DC hybrid versions and can also be easily integrated into existing energy systems. The systems are quick and easy to install and, thanks to the safety concept, can also be installed outdoors without a roof, which saves additional installation costs.

The AC commercial storage system has an output of 125 kilowatts (kW) and a capacity of 261 kilowatt hours (kWh). The AC system is water-cooled, which enables higher energy flows. The air-cooled DC hybrid storage system has a maximum output of up to 60 kW and a maximum capacity of up to 200 kWh. With both systems, up to ten devices can be connected in parallel. The commercial storage units are also capable of emergency power supply and offer maximum protection against damage caused by overheating and fire. The energy flows of the commercial storage units are managed and monitored by an energy management system, which also takes over the operation of the grid-connected inverters and the self-consumption optimisation of the entire system.

New planning tool for commercial solar systems with battery storage

Solarwatt's many years of expertise in the commercial sector have also gone into the selection of new software that enables companies to easily plan their solar system including commercial storage: "We use our tool to examine the company's load profile and calculate the appropriate system size and battery storage capacity. The software also simulates important key figures such as the return on equity, the degree of independence and when the system will pay for itself. We can also use this to analyse whether a storage retrofit for existing systems, storage sizing for future charging infrastructure or, in exceptional cases, even a battery storage system without a solar system is the right solution. This gives businesses a very good overview of what they can expect from their investment," says Peter Bachmann.
