I don't know of any specific thresholds, but it's worth mentioning that 54% of Q2 was renewable, and solar peaks in Q2. Solar was also only 36.8% of that renewable generation (just under 20% of Q2's total), so there's a long way to go before solar is 40% of the total energy mix.

If there is an important threshold when solar reaches 40% of the full year's production, then solar will need to almost quadruple before that's a concern. For all of 2024, solar was 22.4% of renewables, and renewables were 47% of the total[1], meaning that solar was 10.5% of total electricity over the full year.
