To significantly increase the self-consumption proportion of the solar power you produce, you can also use an electrical storage unit in conjunction with your photovoltaic system. These battery storage systems store excess power locally for consumption later in the day or at night. A practical and straightforward way to save on electricity costs is our Q.HOME energy storage system.
Even in so-called low-light conditions, on cloudy or rainy days, or at dusk, Q CELLS solar modules continue producing at high outputs. Q CELLS modules are built for real-life conditions and are recognized for their particularly good performance with diffuse light. Even at a very low irradiation of 200 W/m², our solar modules still achieve 98% of its original efficiency; which means higher returns for you with a minimal amount of sunshine. At radiation values between 400 and 900 W/m², efficiencies over 100% of the nominal value can be achieved. These results have also been confirmed by the independent Fraunhofer Institute for Solar Energy Systems ISE.
Photovoltaics (PV) is a method of direct conversion of sunlight into electricity.
The heart of a PV system is the solar cell. The incident sunlight, i.e. electromagnetic radiation, on the solar cell initiates a physical response whereby the solar cells generate a direct current. In general, a solar module is made up of 60 or 72 solar cells that are electrically connected and safely protected by a tough glass panel and frame. Several modules together make up a powerful and efficient photovoltaic system. The electrical current produced at the terminals of the solar modules flows through the connected cable to the inverter, where it is converted to alternating current so that it can be used by electrical equipment. The French physicist Alexandre Edmond Becquerel first discovered the so-called “photoelectric effect” in 1839 and thus laid the foundation for today’s efficient solar cells and the production of environmentally-friendly electricity from sunlight.
On request, our affiliates cover all the crucial steps of project management as your EPC contractor or project developer. These include the site analysis, plant design, construction planning, financing options, and the creation of output reports. The development, planning, and construction of large-scale solar power plants is a highly complex process, which has been optimized by our specialists.

The output of a solar system and the potential for self-consumption is dependent on several factors: the orientation (North, South, East, or West), the inclination angle of the roof, and the size of the solar system. The share of self-consumption depends on the demand for electricity in a given household – it can increase through intelligent use of solar power and the application of data loggers/monitoring devices and storage systems.
Basically, a solar system is applicable everywhere at least 107.6 ft² (10 m²) of roof area is available. Next to the geographic location, the amount of electrical output is dependent on several factors: the orientation (North, South, East, or West), the inclination angle of the roof, and the size of the solar system.
The assembly time of a solar system depends on its size and the individual requirements of your property. In general, the installation of a residential solar system is accomplished in a few days. In case of power plants, through our affiliate companies, we have realized 50 MWp power plants within a few weeks.
Qcells’ high-quality modules are covered by a 12-year product warranty and a 25-year linear performance warranty.1 In general, a solar system with Qcells modules is trouble-free and low maintenance. However, should any problems arise in the operation of your system, simply contact your local authorized installer.
1 In accordance with the warranty terms of the Qcells distribution organization in your region or country.
