How do grid-tied solar systems work over a year? readwritenews.com
The direction of energy transfers between the home and the grid isn’t just affected by the time of day but also by the seasons. As the season's change, so does the amount of sunlight that hits the panels. At the same, weather changes impact the electricity required for cooling and heating, which happen to be the two biggest users of household energy. Combined, changes in sunlight availability and weather mean that a grid-tied solar system’s level of imports and exports varies greatly by season.
