Just throwing out some ideas even though you may not like them:
- Have you considered not running part of your array to get below the 120% limit? Do you actually get any financial benefit from overproduction?
- Perhaps consider buying an EV to get that usage up a bit?
- Along the same lines, as you replace appliances, is going all-electric a possibility?
- This is really out there, but would you consider bitcoin mining if your marginal cost of electricity is zero?
- Along the lines of increasing usage and monetizing that, are there crops or livestock you could pick up that would take advantage of the potentially free electricity that you have?
Just some thoughts. Apologies if they are too crazy.
