The core of all MHH-Photovoltaic Systems are high quality modules. Their performance is the main component which determines the electrical output of your system – and thereby your return on investment. Every product that we offer meets high standards of quality and is carefully selected for its output and longevity. That is why our product catalogue only contains modules from name-brand manufacturers who utilize their broad photovoltaic expertise in the development of their products.

All of our modules have a low power tolerance: the lower the better, and never more than five percent. A high efficiency rating – above 12 percent – guarantees that the module has a high output even over a small area. And a 20 to 25 year manufacturer’s guarantee on module performance attests to the longevity of the module.
