Two things often ignored when working out the break-even point for solar:
1) having solar installed does generally increase the value of your home. Of course there will be some who won't buy your home because of it, but there will be others who are attracted by it; and
2) the cost of electricity rises every year, whereas the typical break-even calculation uses today's price.
Personally, I wouldn't install solar until the cost of storage comes down enough to make going off-grid feasible.
As others have mentioned, the removal of grants and higher interest rates have made going solar more expensive recently, as have restrictions on importing the panels from China.
