Bosch Solar Energy develops, manufactures, and markets mono- and polycrystalline silicon solar cells characterized by high, stable output with narrow output tolerance. Owing to their high efficiency over long periods and good weak-light performance, solar cells make high energy yields possible even when the intensity of solar radiation is low.

Bosch also produces thin-film solar modules, based on amorphous and micromorphous technology. Bosch Solar Energy actively reinforces its leading technological position with comprehensive research activities, making it a leading provider of silicon-based photovoltaic products with a constant focus on product quality.
