Especially good with this local company is the "all-round carefree package". From the personal and nice advice, to the offer, the installation, to the commissioning, everything went smoothly. Scaffolder, electrician...everything went hand in hand. And nobody had to come from the grid operator, the electrician is authorized to change the meter. We have been recommended GSM-solar and can only recommend GSM-solar. Thank you very much; keep it up!
