Hi, If you make use of electrical appliances primarily when the sun is shining, you use power when solar panels are exporting it to the grid. This helps to even out the supply/demand on the grid.
"Make hay while the Sun shines." Regards, Robin van Spaandonk Drive your electric car every second day and recharge it from solar panels on your roof on the alternate days. The other days, drive your spouses car, and do the same with it. "Charge when the Sun shines".
