Dean has connected tens of thousands of homeowners with residential solar installers across all 50 states since 2021, and works directly with installers on pricing and financing.
Should you put solar on your roof in Puerto Rico? Half of the answer is settled and half of it is in front of a judge. The financial case rests almost entirely on one rule, full retail net metering, which the law protects until 2031 and which the Financial Oversight Board is currently suing to strike down. The other half of the case has nothing to do with any of that: in 2025 the average customer here lost 59 hours of power. One of those halves can change next year. The other one has been getting worse.
The Answer Turns on a Lawsuit Nobody Has Settled
Act 114-2007, as amended by Act 10-2024, credits the power you send back to the grid at the full retail rate, and it bars the Energy Bureau from reopening that tariff until 2031. The island’s average residential price runs about 40% above the US average on the federal EIA’s year-to-date figure of 25.14¢, and the current all-in LUMA tariff is higher still at 29.24¢, so a one-to-one export credit carries unusual value here. A kilowatt-hour you push out at noon is worth exactly as much as one you pull back at 8pm.
Puerto Rico is one answer of fifty; the national payback picture holds the rest.
The Financial Oversight and Management Board filed suit on July 26, 2024 to nullify that amendment, and as of August 16, 2026 that case is still live. Both things are true at the same time, and any page telling you the rule is safe, or telling you it is doomed, is guessing. What you can do is decide with the uncertainty in view rather than pretending it away.
Customers who interconnect before any change keep their terms for 20 years under Act 17-2019, a separate statute from the one being sued over, so interconnecting sooner locks in the current credit for most of a system’s working life rather than merely reducing exposure. What no statute settles is what a household that interconnects after a change would be credited.
What Your Exports Are Worth Under Each Outcome
The table below is about the value of a kilowatt-hour you export. What a system costs, and how long it takes to pay for itself, is the section after it.
If netting | An exported kWh is worth | What that does to your decision |
|---|---|---|
Holds to 2031 as written | 29.24¢, the same as one you buy | Roof size is limited by your roof, not by your usage pattern. Exporting is not a penalty. |
Is struck down, existing systems grandfathered | 29.24¢ for you, less for later buyers | Interconnecting sooner is worth real money. This is the scenario that rewards moving. |
Is struck down with no grandfathering | Unknown, and set by a future Bureau ruling | Self-consumption becomes the whole game. Size to what you actually use and store the rest. |
Notice what the third row does. It does not say solar stops working. It says the value shifts from what you export to what you use and store yourself, which is the configuration most homes here are already buying. That is why the downside case is survivable rather than ruinous, and it is the single most useful thing to understand before you sign anything.

Fifty-Nine Hours in the Dark, and No Judge Can Change That
Here is the part of the answer that does not depend on the litigation at all. The federal government measures how long the average customer spends without power each year. For 2025 the figures for Puerto Rico were:
Cause of interruption | Puerto Rico, 2025 | Mainland US, typical year |
|---|---|---|
Ordinary outages, no hurricane involved | 36 hours, up 19% on 2024 | About 2 hours |
Major events, storms included | 23 hours | Varies by region and year |
Total time without power | 59 hours, about two and a half days | Roughly 2 hours plus event years |
Read the first row twice. Excluding every hurricane, every named storm and every major event, an ordinary year here costs you 18 times the outage time a mainland household accepts, and it got 19% worse in a single year. That is not a resilience talking point. It is the reason 171,372 of the island’s 191,929 rooftop systems carry a battery, an attachment rate near 89% against roughly one in ten on the mainland.
This changes what “worth it” even means. On the mainland, a battery is usually a comfort purchase you justify against a payback figure. Here it is closer to the point of the exercise, and a household that has thrown out a refrigerator of food twice already tends to know that without being told. If your answer depends only on the netting case, you are pricing half the product.
What a System Has To Beat Here
Puerto Rico installers do not post prices, so run the arithmetic on the quote in front of you. A home on 800 kWh a month pays about $234 in energy charges at 29.24¢, or $2,808 a year, plus an $8.00 monthly customer charge that solar does not remove. Divide any quoted price by the share of that $2,808 the bidder promises to erase.
Quoted system price | Years to pay back at 70% bill offset | Years to pay back at 90% bill offset |
|---|---|---|
$18,000 | 9.2 | 7.1 |
$24,000 | 12.2 | 9.5 |
$30,000 | 15.3 | 11.9 |
$36,000 | 18.3 | 14.2 |
$42,000 | 21.4 | 16.6 |
Island quotes nearly always include storage, which is why the middle rows are the realistic ones for a solar-plus-battery system. The battery earns two things the table does not show: $1.00 per kilowatt-hour through LUMA’s Customer Battery Energy Sharing program during grid events, and the hours the house stays on during the 59 hours a year the grid is down. Nobody can put a dollar figure on the second part for you. For a smaller household the break-even date barely moves at the same price per watt, but the fixed customer charge and the battery are a larger share of a smaller system, so the lifetime dollars saved are lower and the bidder’s promised offset matters more.
Who It Already Pays, and Who Should Wait
Solar is not a universal yes here, and anyone telling you otherwise is selling. The split falls along clearer lines in Puerto Rico than in most markets.
- It already pays if you run a high bill and stay put. A household spending $200 or more a month is displacing roughly 650 kilowatt-hours at 29.24¢, power priced about 40% above the US average on the federal year-to-date figure and higher still on the current tariff. Divide the quote by the share of about $2,300 a year the bidder promises to erase; at a realistic island quote that is 12 to 18 years unless the offset is near 90%. Below that bill the same price per watt pays back in about the same number of years, but the fixed costs eat a larger share of a smaller system, so make the bidder show the offset in kilowatt-hours. The netting case puts that value at risk.
- It already pays if outages cost you real money. Medical equipment, a home business, a well pump, or anyone who has replaced spoiled food more than once. That value is independent of the court and has been rising.
- Wait if your roof does. Mounting onto a roof with a few years left means paying to remove and refit the array later, and that cost rarely appears in the original bid. Sequence the roof first.
- Wait if the quote only works with Programa Incentivo Solar in it. That programme is rationed by ticket, not granted on application, so a bid that only clears with $15,000 of it assumed is a bid that has not been stress-tested. Ask to see it modelled both ways.
- Wait if you are selling within a few years. Solar has resale value, but the netting question makes it harder to price right now than it will be once the case resolves.
One thing that is not a variable: the federal residential credit. Section 25D was a credit against federal income tax, and most bona fide Puerto Rico residents owe none on island-source income under IRC Section 933, so it was never practically claimable here even while it existed. Since Public Law 119-21 it is $0 for everyone whose installation is completed after December 31, 2025. If a quote still subtracts 30% for it, the arithmetic is wrong and so is any conclusion drawn from it. The one live federal credit on the island is the separate Section 48E business credit, which a lease or PPA company may qualify for under current deadlines; whether any of that value reaches your payment depends on the contract, so ask for both in writing. Our Puerto Rico incentives guide covers what genuinely remains, and the prices guide explains why island quotes are so hard to compare.
LUMA Credits Exports at 29.24¢, Unless a Court Says Otherwise
Every export decision here starts with LUMA’s tariff. Under Act 114-2007 as amended by Act 10-2024, a kilowatt-hour you send out is credited at the full retail rate, 29.24¢ on the current tariff, and Act 17-2019 keeps that treatment for 20 years once you interconnect. The Financial Oversight and Management Board is suing to strike the amendment, so a proposal should show the payback with full-retail crediting and again with self-use only. An $8.00 monthly customer charge stays either way, and a battery can earn $1.00/kWh through LUMA’s Customer Battery Energy Sharing during grid events. Make the company model your LUMA rate and export credit in writing, both ways.
Puerto Rico Solar FAQs
Are solar panels worth it in Puerto Rico in 2026?
For most high-bill households that plan to stay put, yes, but for two separate reasons that should be judged separately. The financial case rests on full retail net metering at 29.24¢ per kilowatt-hour, which is protected until 2031 and is being challenged in court. The resilience case rests on 59 hours without power in 2025 and does not depend on that case at all.
Is net metering in Puerto Rico going away?
It is being litigated, not repealed. Act 114-2007 as amended by Act 10-2024 credits exports at the full retail rate and bars the Energy Bureau from revisiting the tariff until 2031. The Financial Oversight and Management Board sued to nullify that amendment on July 26, 2024 and the case was still live on August 16, 2026. Nobody can tell you the outcome yet.
How often does the power go out in Puerto Rico?
In 2025 the average customer lost 36 hours to ordinary outages with no hurricane involved, 19% more than in 2024, plus another 23 hours from major events, for 59 hours in total. A mainland customer typically loses about 2 hours a year excluding major events. The 2021 to 2025 average for Puerto Rico is 29 hours a year.
Do I need a battery for solar to be worth it in Puerto Rico?
Almost everyone here buys one. At the end of 2025 the island had 191,929 rooftop systems and 171,372 batteries, an attachment rate near 89%, averaging 16.7 kWh each. Without storage, a grid-tied array shuts down during an outage for safety, so a system with no battery does nothing for you on the 59 hours a year that the power is off.
Is solar still worth it without the 30% federal tax credit?
The credit changes less here than mainland coverage suggests. Under IRC Section 933 most bona fide island residents had no federal income tax to claim it against, and it is now $0 for everyone whose installation is completed after December 31, 2025 under Public Law 119-21. What replaces it in Puerto Rico arrives after the install rather than off the sticker, chiefly full retail export credits, the ticketed Programa Incentivo Solar, battery dispatch payments and the Act 83-2010 tax exemptions. Any quote still deducting 30% for the federal credit is simply wrong.
What happens to my system if the netting rules change?
If you interconnected before the change, Act 17-2019 keeps your terms for 20 years. If you interconnect after it, the export credit would be set by a future Energy Bureau ruling, and the system keeps working and the value simply shifts from what you export to what you use and store yourself. Sizing against your own usage is the practical hedge.

Methodology: the retail rate of 29.24¢ per kilowatt-hour is computed from the LUMA FY2027 tariff book and the Table of Factors approved in Puerto Rico Energy Bureau Order 46203 for the July to September 2026 quarter, retrieved August 16, 2026; riders reset quarterly. Outage figures are EIA SAIDI values for 2025 and are stated separately for ordinary and major-event causes, because combining them hides the trend that matters. Rooftop and storage counts are Energy Bureau figures as of the end of 2025. The netting litigation is described as unresolved because it is; this page takes no position on the outcome.
Methodology: payback figures are simple payback with no financing cost and no rate escalation, on $2,808 of offsettable annual energy charges (800 kWh a month at 29.24¢ under Energy Bureau Order 46203), matching our Puerto Rico cost guide. Over a 25-year life the island’s five-year rate trend of about 2.0% a year shortens every row slightly and panel output declining about 0.5% a year lengthens them slightly. Riders reset quarterly, so refresh these figures each quarter. The netting litigation was unresolved as of August 16, 2026. Reviewed August 2026.
