First revealed at last years Intersolar Europe exhibition in Munich in June, SolarWorlds new bifacial modules and flexible lithium-ion home storage batteries are set to be unveiled to the market at next months Light + Building show in Frankfurt.
The German solar company has hinted at further innovation in both the module field and storage sector for many months, and it appears that the firms latest products for both sectors are one step closer to market.
Its Sunmodule Bisun module is a glass-glass module that comprises 60 bifacial cells based on PERC technology. According to SolarWorld, this ensures a 25% increase in energy yield, plus a longer lifespan and added durability is attained because the cells are embedded into the glass and thus protected against external environmental and mechanical influences.
Able to utilize incident light on both the front and rear, this double-sided module thus absords a higher portion of sunlight, and is particularly suitable for flat roofs and ground-mounted systems where more light is reflected from surrounding surfaces. With higher yield and a longer life, SolarWorld believes that the power generation costs per kWh are significantly lower than standard modules in the field.
The expected growth of the German home storage sector this year has shaped SolarWorlds efforts to remain a key concern for residential solar customers, and its SunPac LiOn storage system has been designed to meet the needs of such consumers.
Starting with a storage capacity of 2 kWh, the battery can be scaled up to 10 kWh in increments of 2 kWh, meaning it can expand or contract to mirror the energy storage needs of an average home. SolarWorld adds that the lithium-ion cells ensure 10,000 complete charge and discharge cycles, which would equate to around 20 year of service life for most households.
The system is connected on the AC side, so is easily retrofittable to existing solar systems and inverters, and has a charge controller that automatically recognizes the number of battery modules connected and the scale of power required.
Both components are set to be unveiled at the Light + Building show in Frankfurt, 13-18 March.
