PV-Ready Checklist
DOE Zero Energy Ready Home National Program Requirements Mandatory Requirement 7
(Renewable Ready) shall be met by any home certified under the DOE Zero Energy Ready
Home program, only where all three conditions of the following conditions are met. If any of
these three conditions is not met, the home is exempt from requirements contained in the PVReady checklist.
1. Location, based on zip code has at least 5 kWh/m2/day average daily solar radiation based
on annual solar insolation using PVWatts online tool:
http://gisatnrel.nrel.gov/PVWatts_Viewer/index.html AND;
2. Location does not have significant natural shading (e.g., trees, tall buildings on the southfacing roof, AND;
3. Home as designed has adequate free roof area within +/-45° of true south as noted in the
table below.

Note:


If a solar photovoltaic system is included with the home, then compliance with the Consolidated RERH checklist
is not required.

These requirements were adapted from the EPA’s Renewable Energy Ready Home Solar Photovoltaic Specification
Guide (RERHPV Guide). For further guidance on any of the above items, this checklist notes the section of the
guide. This guide can be accessed on the DOE Zero Energy Home program website at
http://www1.eere.energy.gov/buildings/residential/pdfs/rerh_pv_guide.pdf

Designate a proposed array location and square footage on architectural diagram:
PV _________________ sq.ft. (RERHPV Guide 1.1)

Identify orientation (Azimuth) of proposed array location:
PV _____________ degrees. (RERHPV Guide 1.2)

Identify Inclination of proposed array location:
PV_______________ degrees. (RERHPV Guide 1.3)

Provide code-compliant documentation of the maximum allowable dead load and
live load ratings of the existing roof; recommended: allowable dead load rating can
support an additional 6 lbs/sq. ft. for future solar system. (RERHPV Guide 2.1)

Provide architectural drawing of solar PV system components. (RERHPV Guide
3.5)
Alternative: Provide home buyer with the following information:
 List of renewable-ready features
 Available free roof area within +/- 45° of true south
 Location of panel or blocking for future mounting of PV system components
 Location of Breaker or slot for future breaker in electrical service panel
 Copy of the PV-Ready Checklist
 A copy of the RERH Solar PV Specification Guide

Install a 1” metal conduit for the DC wire run from the designated array location to
the designated inverter location (cap and label both ends). (RERHPV Guide 3.2)

Install a 1” metal conduit from designated inverter location to electrical service panel
(cap and label both ends). (RERHPV Guide 3.3)

Install and label a 4’ x 4’ plywood panel area for mounting an inverter and balance
of system components. (RERHPV Guide 3.1)
Alternative: Blocking is permitted to be used as an alternative to the 4’ x 4’ panel.
The area designated for the future panel to mount PV components shall be clearly
noted in the system documentation.

Install a 70-amp dual pole circuit breaker in the electrical service panel for use by
the PV system (label the service panel) (RERHPV Guide 3.4)
Alternative: Provide a labeled slot for a double-pole breaker in the electrical
service.
