Choosing and comparing the best energy data logger to install in your panels for small buildings in 10 minutes

Panel builders, installers, engineering department,…Before the multiplication of energy efficiency solutions to install in the small buildings and commercial buildings, you are facing many difficulties to choose the best technology for the energy collection; the one which will address the needs of your customers, while being easy to use and to install.

The lack of information, knowledge and means makes you take a risk and also lose valuable time.

Installing an inappropriate device, partially replying to the technical requirements specifications, calling on a local collaborator whom reliability and reputation remain uncertain, taking a specific programme causing additional cost, is a significant risk factors and does not guarantee the working of your installation.

A lot of panel builders – maybe like you? – do not even respond to a call to tender involving energy efficiency solutions! Yet, theses are increasing demands and you won’t be able to develop your company without incorporating these solutions in and earning this expertise.

Facing this issue, we decided to go into action to test solutions for energy data logger for small buildings and commercial buildings. Here is how we made these tests:

We dissociated two aspects:

  • The connectivity of the data logger and the interfacing possibilities
  • The configuration of the software (i.e user-friendliness and features)

We’ve rather compared solutions intended for panel buildings and products from manufacturers who propose offers available in the greatest number of countries.
