Exercise 3.6.- Based on the data above, what is the autonomy of this installation in days In other words, how long can die batteries supply the loads with no PV production and no input from the electrogen group  

6 By way of indication, 1 kWh is consumed, for instance, by one cycle of the washing machine or an hour of ironing, to say nothing of the more powerful energy-hungry functions because, of course, in such an installation, the heating could not be electric. 

7 For a photovoltaic installation injecting power into the grid, we wish to maximize the amount of energy produced throughout the year, so we incline the panels 30° from the horizontal (in the south of France). 

Over a 5-month period in winter (October to February), the EG provided 

8 In order to avoid too low a state of charge of the battery and damage to it, the electrogen group is started when the battery voltage dips below a value set by the regulator.
