You don't need 30% more panels, you need to store energy for the all usage for about a week.

We should probably be investing more on research about synthetic fuels than we are right now (and shelf-stable flow batteries; hydrogen won't cut it in a micro-scale, even though it's great for national grids), but for a long time everybody will still use fossil fuels for that. It's not a huge problem right now.
