I've had a few friends run into this issue with systems almost frying inverters because they didn't allow enough headroom for open circuit voltage coming from the panels.

Ontario gets 21% of it's power from hydro-electricity which provides closer to baseline power than variable-generation. The report never mentions hydro (although due to a quirk all electricity is called hydro in Ontario and BC) which is concerning.. Nuclear generation isn't particularly large at 2x hydro, gas 1x, solar and wind are less than half. Gas is the only peaking source listed.

Indeed, so how do you replace the gas peaking? Solar, wind, batteries, existing nuclear and hydro, and perhaps some balancing with existing interconnects with Manitoba, Québec, NYISO, and MISO.

(75% of Ontario's trailing twelve months electrical consumption was generated by low carbon technologies, the remainder is the gap to fill; adjacent Manitoba and Québec grids stand at 90%+ low carbon for the same time period)

Next gen solar and batteries are going to wipe everything else away. PV will hit 40% conversion efficiency, sodium and solid state batteries will reduce costs and eliminate flamability issues while providing longer lifespans, capacitive battery tech will last indefinitly, as solar PV does now. I cant help it if the truth trolls the haters, and often I bite my ,my finger, but hey it's tuesday

If competing means 25-75% more expensive
