Best thing I did with my solar system is use a different energy provider. PG&E was paying me $0.02/kwh for energy I exported to the grid (flat rate, not TOU adjusted), now I only pay PG&E for transport/meter fee, which is less than $10/month.
My new provider (SVCE) pays me the same as they charge for the time of day the energy is exported. My battery sends 5kWh to them every day starting at 4pm, which is when peak hours begin.
It doesn't sound like much, but that's every day and it's in addition to the energy I export all day that I'm not consuming. My true-up winds up around $1500/year and that's with an EV charging at home. With PG&E it was less than $600/year.
