When I started researching solar panels and battery backup it soon became very clear to me that it was a complicated subject. Things to be considered included the correct size of the system, was my house suitable, what manufactures products to use, the various methods to operate the solar panels, what type of inverter, the size of the battery and of course the price! When I first contacted EPC I was put in touch with Kai and he was crucial in my decision to use EPC. Throughout the initial stages he was always available and patient in answering my many questions about the design of the system. Most importantly he listened to what I wanted the system to do and then recommended solutions accordingly. The actual installation took longer than was planned due to unforeseen problems. However, the problems were all resolved to my satisfaction and the completed work is neat and tidy. The system has now been operating for a month and the data shows that I will be reducing my electricity usage from the grid by a considerable amount. I am very pleased. Will I recommend EPC to others? YES.
