If options 1 and 2 are problematic or too difficult, the easiest way for a homeowner to reduce high grid voltage issues is to self-consume as much solar energy as possible. Increasing self-consumption will reduce the amount of solar being exported and thus reduce the grid voltage; it will also help save money by using less energy from the grid.
Strings of solar panels operate at high voltages, up to 600V or higher. Operating at these elevated voltages over many years can, in some cases, allow a current leak to develop through the cells to the aluminium frames of the solar panels and into the earth, resulting in a significant performance loss.
If you have solar and receive an unusually high electricity bill, this generally does not indicate that your solar system is not working correctly. There are many reasons for your electricity consumption to increase, which may not be obvious at first.
