Service types

Site assessment

Shade, roof age, structure, and electrical service, before anyone talks about a system size.

Questions to ask

  • Did someone look at the roof in person, or is the proposal from aerial imagery only?
  • How old is the roof, and who pays if it needs replacement before the array goes on?
  • What is the size of the existing electrical service?

Roof-mounted systems

How an array is attached, flashed, and warranted relative to the roof.

Questions to ask

  • What attachment and flashing details are specified?
  • Whose warranty covers a roof leak at a penetration: the roofer, the installer, or neither?
  • What happens to the array if the roof is replaced later?

Equipment questions

Modules, inverters, and monitoring. Ask what is specified, not what is typical.

Questions to ask

  • Are the module and inverter models named in the contract?
  • Is the inverter a string inverter or module-level electronics?
  • Who can monitor the system, and who you call when production drops?

Permits and interconnection

The building permit and the utility's permission to operate.

Questions to ask

  • Who pulls the permit and files the interconnection?
  • Is permission to operate required before the system is turned on?
  • What is excluded if the utility or the building department requires a change?

For homeowners

  • A proposal built only from a satellite photo has not seen the deck, the flashing, or the electrical panel.
  • Ask whether the contract is for a purchased system or a third-party arrangement. Read who owns the equipment.
  • Ask who owns the panels after the install, and who you call when an inverter goes quiet.

Questions

What do I say when I call?

City, roof age, and whether the electric bill is the reason you're calling.

Can you price a system on this call?

The call sets the visit. A real number comes from the roof, the panel, and the bill.
