We turned to C21 srl for the installation of a 5.80 kWp photovoltaic system with a 16 kW storage system and a wallbox. Absolutely everything was perfect; the team was precise, competent, friendly, fast, and professional. Completely satisfied! Thanks to Francesco, Stefano, Dario, and Ivan!

I installed a photovoltaic system with storage at home. They are attentive, competent, reliable, and helpful professionals. They completed the work on time and took care of all the necessary paperwork. Stress-free. Communication was always prompt and timely. Well done! Definitely recommended.

I'd say it was an excellent experience: quick installation, adherence to schedule, and clear explanations both during the sales phase and after installation regarding operation and management. Not to be underestimated... they clean and take away packages and miscellaneous items after work... that's not a given these days!!!! Well done. After a month, everything is working very well.

I had a photovoltaic system installed and I must say I'm very satisfied with the work done. High-quality materials with an excellent warranty, and highly trained sales and installation staff. They patiently supported me throughout the entire process, from the estimate to the commissioning of the system. The installation took two days, very quickly despite the complex nature of the work. They were also willing to do additional work. I highly recommend this company.

They installed two photovoltaic systems and a wallbox for me, and I can say I'm truly satisfied with this company. The materials used are top-quality, the technicians are truly knowledgeable and attentive to every technical and aesthetic aspect, and the sales support is commendable. A truly positive experience, I highly recommend them. Less talk, more action.
