Running a 6 foot line from a existing transformer to a box took 2 years. Getting the solar permitted and feeding was another 12 months. Permit review for generator install was another 12 months.
Labor and permitting was > 50% of solar project cost and of generator install.
Permitting and “engineering” was > 90% of grid hookup price, but dwarfed by the cost of the delay (had to run gas generator for about a year as a workaround).
If it was compatible with getting a mortgage, we’d ge 100% off grid and probably $20-50K richer.
