Question 1

A PACE-financed commercial building installs a 200 kW rooftop solar system. If the utility's interconnection standard requires anti-islanding protection, which inverter feature satisfies this requirement?

Accepted Answer

Automatic disconnection upon grid outage

Answer

Anti-islanding protection requires the inverter to automatically disconnect from the grid when utility power is lost, protecting utility workers from energized lines.

Question 2

Under a typical PACE program, which party holds the superior lien position relative to the PACE assessment on the property tax bill?

Accepted Answer

Property tax authorities

Answer

Property tax liens are senior to most other liens, meaning the PACE assessment—collected like a property tax—generally has priority over the first mortgage.

Question 3

Which renewable system type is most appropriate for a PACE-financed coastal commercial property seeking to reduce electricity and thermal loads simultaneously?

Accepted Answer

Combined heat and power (CHP) with solar thermal

Answer

A CHP system with solar thermal collectors can simultaneously generate electricity and capture heat, addressing both electrical and thermal loads in a single PACE-eligible package.

Question 4

In PACE project underwriting, a 'simple payback period' of 8 years on a 20-year PACE term indicates what about the investment?

Accepted Answer

Energy savings will exceed PACE payments well before the assessment term ends

Answer

A simple payback shorter than the PACE term means cumulative energy savings will surpass the project cost before the assessment period ends, indicating strong financial viability.

Question 5

Which solar racking system type is specifically designed for flat commercial rooftops and avoids roof penetrations by using ballast weight?

Accepted Answer

Ballasted low-slope rooftop racking

Answer

Ballasted rooftop racking systems use weighted blocks to hold panels in place on flat roofs, eliminating the need for structural penetrations that could void roofing warranties.
