Four vetted installers serve Puerto Rico in our network, and the one that deserves your roof is the one whose crews are still on the island the week after a hurricane. On the mainland you compare warranties. Here you compare storage capability and who answers the phone when the grid is down.
Our Top 4 Solar Companies in Puerto Rico
Every company below was checked against its own website in August 2026: years operating, island base, storage capability and stated registrations. Nobody paid to appear. Where a company does not state a figure, we say so rather than fill the gap.
WindMar Home
The longest operating record on this list and the most homes served of anyone on the island, with over 70,000 families served by the company’s own count. It also seals roofs, which matters more here than most buyers expect: the roof under the array is the part the storms test.
ProSolar Systems Puerto Rico
A Carolina-based installer with more than a decade on the island, certified for Tesla Powerwall and stating that its systems are engineered to withstand Category 5 hurricane winds. If backup power is the reason you are buying, this is the conversation to have first.
Power Solar PR
Ten offices from San Juan to Mayaguez, which is the most distributed service presence on this list and the reason to shortlist them if you live outside the metro. Installs Tesla, Enphase and Fortress Power storage, and shows registration with DACO and the Department of Economic Development and Commerce.
Maximo Energy
Formerly Maximo Solar, now operating as Maximo Energy from Aguadilla, with more than 12,000 homes energized by its own count. The western base is the differentiator: crews close to Aguadilla, Mayaguez and the northwest coast rather than dispatched from San Juan.

Notice the last column. Puerto Rico companies share far less warranty and timeline detail up front than mainland ones, so the burden of getting terms in writing sits with you here more than anywhere. Enter your ZIP code and we will start that conversation with the companies serving your municipality.

How We Rank Solar Companies
Rankings are built from what we can verify, never from who pays us. Five weighted factors:
Puerto Rico’s weighting differs from our mainland states on purpose. Storage capability and island service presence carry weight here that warranty paperwork carries elsewhere, because a system that cannot run through an outage has not solved the problem most Puerto Rico homeowners are buying to solve.
Frequently Asked Questions
WindMar Home, ProSolar Systems Puerto Rico, Power Solar PR and Maximo Energy make up our vetted Puerto Rico network for 2026. WindMar has the longest island record, ProSolar is Tesla Powerwall certified with hurricane-rated design, Power Solar has ten island locations, and Maximo Energy serves the west from Aguadilla.
Storage capability and island service presence. A grid-tied system without a battery shuts down during an outage, and crews based on the island respond differently after a hurricane than technicians flown in. Those two factors matter more here than the warranty comparisons that dominate mainland decisions.
Most companies on the island share less warranty and timeline detail than mainland installers do. That is not automatically a warning sign, but it does shift the burden onto you: ask for workmanship coverage, equipment warranties and service response commitments in writing before signing.
Enrollment in Customer Battery Energy Sharing happens through your equipment provider or aggregator rather than with LUMA directly, so ask each installer which aggregator they work with and what the contract pays per kilowatt-hour delivered during grid events.
No. Placement on this page is never sold. Rankings come from verifiable facts the companies state themselves, weighted toward storage capability and island service presence because those decide whether a Puerto Rico system does what its owner bought it for.
Shortlists are easy. Matching one to your roof, your municipality and your outage history takes more digging. Enter your ZIP code and we will do it for you.
