Oregon limits residential customers to 25 kW (nameplate capacity). https://oregon.public.law/rules/oar_860-039-0010 https://oregon.public.law/rules/oar_860-039-0010 From the cursory look it seems like most states have limits like those. A lot of them are generous enough so you don't have to worry about it. But there are some states where covering an entire roof of a moderately sized building would put your over the limit. https://www.ncsl.org/research/energy/net-metering-policy-overview-and-state-legislative-updates.aspx#statenet https://www.ncsl.org/research/energy/net-metering-policy-ove...
