What happens to my solar production at night or when it’s cloudy outside?

Solar systems convert sunlight into energy, so you definitely need the sun’s rays to make that happen. Weather conditions, the season of the year and time of day all have an impact on how much energy your system generates. On cloudy or foggy days when your production is less, or at night when your system isn’t producing at all, your home will be powered by energy from the electric grid. Interconnection of your system to the grid makes this possible.
