: Why don’t all buildings use solar panels on their roofs to generate electricity?
In: Technology
AND, without storage (battery) most of the solar energy production is wasted in private installation as peak production is midday when consumption in homes are the lowest and no solar help in the morning or evening when it’s needed. Yes, you can still get paid in some countries to feed the grid but it’s predicted to reverse in the coming decade and in southern Europe you already only get a fraction for what you sell compared to the purchase price. Solar panel prices have dropped, now battery prices need to follow and bidirectional charging of cars need to get traction.
