Since Q-Cells SE was established in 1999, it has grown into one of the world’s leading photovoltaics companies. Its extensive product portfolio ranges from solar cells, crystalline and thin film solar modules to turnkey photovoltaic systems. Q-Cells’ products are developed and manufactured at its headquarters in Bitterfeld-Wolfen (Germany) and marketed via its global sales network. It also has a second production plant in Malaysia. The more than 200 scientists and engineers at Q-Cells are working to swiftly advance solar technology and achieve Q-Cells’ twin aims: driving down the costs of photovoltaics quickly and permanently, and making solar power competitive.
SMA Solar Technology AG is the worldwide market leader for solar inverters, a leading supplier of transformers and chokes, and a provider of innovative energy supply solutions for mass transit and main-line rail transportation.
The inverter is technologically the most important component in any solar power system: it converts the direct current generated in photovoltaic cells into alternating current suitable for the grid.
KACO began manufacturing sine inverters more than 60 years ago. The product portfolio offered by KACO today is being used around the globe for rail vehicle and photovoltaic applications. KACO new energy begins in 2010 as the world's second largest manufacturer of photovoltaic inverters. With over 3 GW of inverters in operation worldwide KACO is a trusted and reliable partner for photovoltaic systems across the globe.
With its focus on Renewable Energy and “Green” power solutions, Power-One has recently established itself as the world’s second largest provider of solar inverters. Further, as one of the world’s ten largest providers of power conversion and power management solutions, Power-One is one of the few companies with the product breadth to support every step in the refinement of utility-grade AC into the various DC voltages required to power high-availability infrastructure systems at the site, system, and semiconductor levels.
