It is critical to know where the DOE program does not align with Main Line standards and how this is represented in the Electrical Adders Section.
For all intents and purposes the definitions outlined in the PR: Solar Ready Repairs article - MUST PERFORM and MAY PERFORM are suspended as the entire home system is considered to be Within the Circuit Path.
The Puerto Rico Main Line program requires adherence to the Main Line Electrical Adders Article as there are standards and limitations on pricing as opposed to the practices within the DOE - Solar Access Program.
Some of the main considerations to be aware of:
Section A - All electrical adders must be directly related to facilitating the installation of PV or PV + Battery installation and included with the Quote Generation.
Section B - Panels ANYWHERE in the home interacting with the PV + Battery Installation require remediation.
Section D - Any conditions within the home related to hazardous or unsafe conditions are required to be addressed as part of the installation.
All electrical adders must be directly related to facilitating the installation of PV + Battery installation.
When reviewing the electrical conditions of a project, the system should be designed to avoid or replace certain panel and breaker manufacturers to ensure code compliance.
Common service panel types and manufacturer equipment that are required to be replaced:
Pushmatic / Bulldog
Federal Pacific / Stab-Lok
Zinsco / GTE Sylvania
Fuse Box / screw in fuses and/or cartridges
Other conditions requiring assessment:
Challenger Service Panels - Backfeed using a non-challenger breaker only.
Split/Hot Bus Panels - Non compliant per NEC
60a service meters for single family residences / meter button cans will need to be replaced/upgraded.

Clarity on Over Voltage (OV)
Voltage measurements should be taken at Site Assessment.
Please ensure voltage measurements taken during the install process are not egregiously different than the values taken at Site Assessment. This can be an indication of improper install practice.
Also ensure to provide voltage measurement photos after the install has been completed.
The acceptable voltage range is 106v - 127v per phase. (PREPA_2024)

LUMA High Voltage
Proactively recognize voltage issues early and call them out (as early as Site Assessment).
Guiding customers through the LUMA process to file a case/request to correct voltage issues in their localized area of the grid. This will help to avoid voltage problems at M2.
Guidance on High Voltage cases with LUMA: High Voltage SOP
Have homeowner report high voltage fluctuations at their address through the phone number provided or at a nearby LUMA Customer Service Center with their government issued ID
At M2, please provide the LUMA Case Number whenever high voltage is present
