I have installed 200kw+ worth of rooftop (Florida) and ground mount (NorCal) resi systems (primarily Enphase, but I'm familiar with the operating requirements of other inverters), and am currently riding shotgun for a ~200MW solar PV project in the Midwest. If you share more details (general location, utility, and energy cost schedule [static, seasonal]), I am happy to provide some guidance.
With solar panels being so much cheaper than 10-15 years ago, it seems like installation costs are the biggest hurdle to wider adoption. Do you see anything reducing those costs in the future?
Maybe we need a push to make standing seam metal roofs more mainstream and people can install their own without having to drill into their roof
