According to statistics, each installed kW will produce about 3-4kWh/day (in the South) or 3 – 3.5 kWh/day (in the North). There are 2 ways to monitor. Firstly, we can install an electric meter at the output of the inverter, which will measure all the accumulated electricity that the màsolar system has produced. From there, the owner of the household (factory, business) will know how much he has saved. The second way, we attach a monitoring device with WIFI, this device will collect all operating data of the system and upload it to the website, the owner after setting up an account on the website can monitor operating parameters (output per day, month, year, peak capacity, …) at any place via internet.
