PR: Program Comparison | Palmetto LightReach PR Program

The Puerto Rico Main Line program follows the same overall structure as the DOE Solar Access Program but with critical differences across equipment, site eligibility, and electrical conditions. These differences must be understood to avoid project delays, rejections, or disqualification.

How to tell the programs apart?

Articles for the Puerto Rico Main Line program are labeled with the prefix “PR:”

Articles for the DOE Solar Access Program are labeled with the prefix “DOE”

Always confirm the prefix to ensure you’re following the correct program requirements. For an overview of all program requirements, refer back to our Overview & Quick Hits article.

Category	Main Line Program	DOE Program
Sales & NTP	Credit check required All projects require ≥10kWh battery	Terms and Condition form required No credit check No title check requirement
AVL	Modules All Procurable Module Types EXCEPTING mods that require Pre-Approval (DO NOT USE) Racking All Procurable Racking Types All flat roof attachments require secondary waterproofing (E-Curbs) or integrated waterproofing Inverters All Enphase & Tesla Inverter models acceptable in the ML Program Battery All Enphase & Tesla Battery models acceptable in the ML Program	Modules QCells Racking Iron Ridge and S-5! products Inverters Generac Battery Generac
Site Eligibility	Roof Types Pitched Roof Concrete / Cement Tile Comp-out/composition insert of a clay tile roof area Flat Roof All flat roof attachments require secondary waterproofing (E-Curbs) or integrated waterproofing Roof Quality Ponding in areas of installation is prohibited and results in project DQ Older Concrete Surfaces (cracking and crazing) are Disqualified Second Systems and Add Ons Strictly prohibited.	Roof Types Flat Roof EPDM Modified Bitumen (ModBit) Rolled Asphalt/Composite Concrete (Exposed or Coated) Pitched Roof Asphalt Shingle Metal - Corrugated or Standing Seam Roof Quality Some Degree of Ponding is allowable Older Concrete Surfaces Approved Structure Types Residential, Single Family Homes Detached Garage / Guest Suite
Electrical Conditions & Adders	Electrical Adders (Solar Ready Repair) Adder Price point for projects that need qualified upgrades, no DQ Limit on adders Prohibited Electrical Panels Interconnection (upstream or downstream) of any DQ panel types is prohibited under LightReach policy. Utility Connection Exceptions made - Disconnect Height, Enclosure Position/condition, and Internal Rework Electrical Conditions If any one of these conditions are met, replacement is required: Greatly expanded requirements for electrical issues.	Electrical Adders (Solar Ready Repair) Limited to $3000, tracked and reimbursed as part of the program. Prohibited Electrical Panels Upgrades are ONLY required if In Circuit Utility Connection Exceptions made - Disconnect Height, Enclosure Position/condition, and Internal Rework Electrical Conditions In Circuit & Out of Circuit definition consolidated work to the system being installed EXCEPTING overall safety concerns.
Design & Documentation	• Standard Design Package deliverables (inputs, as-builts, drawings) • M1 Photo Documentation required • Module moves and inverter/battery swaps require updated as-builts	• DOE requires Site Readiness Audit Program (SRR) • Additional DOE forms and deliverables (e.g., spec sheets, beneficiary documents) • Some design changes require DOE review
Installation (M1)	• Standard installation photo documentation (M1) • Vendor must follow AVL-approved equipment and installation practices	• DOE requires specific installation checklists (e.g., SRR recommendations, over-voltage resolution steps) • Extra DOE deliverables: Permit uploads, Connector Guide, PWRcell mode (Clean Backup) setup
Monitoring Portal	• Standard Palmetto monitoring portal access process	• DOE requires specific DOE site ID for portal setup
