Ready-made photovoltaic sets of solar micro-power plants

Why up to 50% cheaper?

Full Kit 40 KW Photovoltaic system available for installers only

Ready-made photovoltaic / solar power plants for self-assembly and installers. Micro power plants were designed by a team of engineers from PVGroup. Trouble-free operation, high yields of electricity and a quick return on investment were the goal of the project team of PVGroupl engineers. Solar power plants can be easily installed on a metal tile, roof tile or on the ground. Rely on the many years of experience of engineers who passionately create solutions from renewable energy sources. 

Photovoltaic sets designed and prepared by PVGroup contain all the necessary elements: appropriate rails and connectors, roof holders, clamps, the latest photovoltaic panels, inverters, lightning arresters and cables.

40 KW photovoltaic set - Rely on many years of experience of enthusiasts of renewable energy sources and choose a solution from carefully selected components. Enjoy cheap electricity for many years to come! 40KW photovoltaic set / complete power plant photovoltaic was prepared by a team of engineers from PVGroup.pl. The goal that we set for the engineers was efficiency and reliability, intended for a minimum of 20 years of trouble-free operation, assuming a minimum return on investment. The task turned out to be a challenge that a team of engineers worked on with the support of producers of photovoltaic equipment. One of the important factors was insolation in this geographic location. Thanks to close cooperation with engineers and service technicians of producers, whom we are a direct representative in Poland, we were able to obtain optimal parameters photovoltaic power plants.


We offer a complete 40KW photovoltaic set for self-assembly 40kW solar power plant with a pape or trapezoidal mounting system.
