## What is a refurbished solar panel?

A refurbished solar panel is a used module that was tested, repaired if needed and retested before being sold with a declared grade. The grade comes from measured power, not nameplate power. The module keeps its original brand, model and nameplate: it is sold as used, not as new.

At Ecobaterías we call this work refurbishment (refacción). [Chile’s Extended Producer Responsibility law (Ley REP, Law No. 20,920)](https://ecobaterias.org/en/chile-epr-law-batteries.html) calls it preparation for reuse: checking, cleaning or repairing a discarded product so it can be used again without any other processing (art. 3 No. 18). It counts as valorization (recovery), just like recycling (art. 3 No. 30). Every term is defined in the [glossary](https://ecobaterias.org/en/glossary.html).

Used, repaired, refurbished or second life: what each one means

| Term | What it means | At Ecobaterías |
|---|---|---|
| Used panel | A module that has already operated. Untested, its real power and insulation are unknown. | We do not sell untested modules. |
| Repaired panel | A specific fault was fixed: junction box, bypass diode, connector, cable or frame. | Wet insulation retest after repair. See [solar panel repair](https://ecobaterias.org/en/solar-panel-repair.html). |
| Refurbished panel | Tested, repaired if needed, retested and graded by measured power. | Label, per-module report and 1-year seller’s warranty. |
| Second life | Used in an application other than the original one, for example an off-grid system. | Grade P3, subject to the requirements of the SEC (Superintendencia de Electricidad y Combustibles, Chile’s electricity and fuels regulator). |

## Are you buying panels or do you have panels to refurbish?

The service has two routes: buy modules that are already tested, or send us yours to refurbish. Our other battery and panel services are listed under [all services](https://ecobaterias.org/en/servicios.html).

### You buy refurbished panels

You order by power and quantity. We offer batches of a single model, sorted by grade and measured-power band, with the test data sheet of every module before you pay. [Get a quote for refurbished panels](https://ecobaterias.org/en/contacto.html?segmento=compra-paneles).

### You send your panels for refurbishment

We coordinate pickup or receive your batch, test it, repair what can be fixed and return every module with a label and a report. Whatever cannot be used is recycled with a certificate. [Send my panels for refurbishment](https://ecobaterias.org/en/contacto.html?segmento=paneles).

## How do we grade panels by measured power?

We measure the power of every module with an I-V curve under a solar simulator, using a calibrated reference module, and correct it to standard test conditions (STC: 1,000 W/m² and 25 °C). The I-V curve is the relationship between the module’s current and voltage; it gives maximum power (Pmax), open-circuit voltage (Voc), short-circuit current (Isc) and fill factor. Measured Pmax, as a percentage of nameplate power, sets the grade.

*Measured-power grades as a percentage of nameplate power. Ecobaterías in-house grading, not a standard.*

Sales grades and recommended use

| Grade | Measured power (% of nameplate) | Additional requirements | Recommended use |
|---|---|---|---|
| P1 | ≥ 85% | Insulation passed and no critical EL defects | Reuse in the same function. Grid connection only with an SEC-authorized model, as defined by the licensed electrical installer and after checking with the SEC. |
| P2 | 80–85% | Insulation passed and no critical EL defects | Same as P1. |
| P3 | 70–80% | Insulation passed and no critical EL defects | Off-grid uses (pumping, irrigation, backup, remote sites and social projects), subject to SEC requirements. |
| Recycling | < 70% | Or insulation failure, broken or cracked glass, delamination reaching the edge, or burn marks | Not sold. Recycled with a valorization certificate. |

Why the cutoff at 70%? The European CIRCUSOL project proposed treating a module as functional when it keeps at least 70% of its rated power, and IEA-PVPS notes that the value is partly arbitrary until a standard exists (report T13-37:2026). Within each grade we sort modules into 5 W power bands, so a given string gets similar modules: the SEC’s RGR No. 02/2024 technical instruction limits mixing modules with different characteristics in one installation and requires the mix to be justified in the drawings or the project report.

## What does each module’s data sheet include?

Every module we sell carries a label with its measured power, attached next to the original nameplate without covering it, and a test report with this data:

What each module’s report measures and against which reference

| Data | How it is obtained | Reference |
|---|---|---|
| Identification | Brand, model, serial number and original nameplate data, recorded when the module arrives | Manufacturer’s nameplate |
| Pmax, Voc, Isc and fill factor | I-V curve under a solar simulator, corrected to STC (1,000 W/m², 25 °C) | IEC 60904-1 and IEC 60891:2021 |
| Electroluminescence (EL) image | Infrared photograph of the module powered in forward bias in the dark: it shows microcracks, inactive cells and damaged solder joints | IEC TS 60904-13:2018 |
| Insulation | Dry insulation resistance: a module larger than 0.1 m² passes at 40 MΩ·m² or more. Wet leakage (the same measurement with the module immersed in a conductive solution) by sampling and on 100% of repaired modules | IEC 61215-2:2021 (MQT 03 and MQT 15) |
| Visual inspection | Under at least 1,000 lux: glass, backsheet (rear sheet), frame, junction box, burn marks and delamination (layers of the laminate coming apart) | IEC 61215-2:2021 (MQT 01) |
| Bypass diodes | Function test of the diodes that route current around a shaded or damaged part of the module | IEC 61215-2:2021 (MQT 18) |
| Repairs | What was replaced (box, diode, connector, cable or frame) and the retest result | — |
| Grade | P1, P2 or P3 and 5 W power band | Ecobaterías protocol |

Sources: [IEC 61215-2:2021 (preview)](https://cdn.standards.iteh.ai/samples/101269/e9c169bfdf004586a8c0cf8bf9e2a625/IEC-61215-2-2021.pdf) · [wet insulation threshold](https://en.millennialsolar.com/news/314.html) · [IEC TS 60904-13:2018](https://webstore.iec.ch/en/publication/26703) · [IEC 60891:2021](https://webstore.iec.ch/en/publication/61766) · 2026-09-26

Dry testing alone is not enough. In a 2026 study of 37 modules from utility-scale plants, 8.1% failed the dry insulation test and 21.6% failed the wet one (Sustainability journal, 18(3):1212). That is why every repaired module goes through the wet leakage test again, as IEA-PVPS recommends for every repair except cable and connector replacement.

This is the same data that the US R2v3 standard (Appendix G) requires certified sellers to disclose: measured power at STC, the percentage of design power and every repair made. The draft IEC PAS 63525, the IEC’s first document on module reuse (not yet published), also calls for an additional reuse label that does not cover the original one. We cite both as references for our method: they are not Ecobaterías certifications.

If you need modules tested at your plant without buying or selling them, see [solar panel testing](https://ecobaterias.org/en/solar-panel-testing.html).

## What are refurbished panels used for?

They suit projects that need known, documented power. These are the usual uses and the grade we suggest for each:

Uses, suggested grade and the condition you should check

| Use | Suggested grade | Condition |
|---|---|---|
| Off-grid systems: rural homes, shelters, remote sites and camps | P1, P2 or P3 | The SEC’s ITG RIC No. 9.1 also requires authorized models |
| Solar irrigation and pumping in agriculture | P2 or P3 | Same authorized-model requirement |
| Backup for small businesses and telecommunications | P1 or P2 | Same authorized-model requirement |
| Social and municipal projects | P1, P2 or P3 | Same authorized-model requirement |
| Grid connection (distributed generation, Law 20,571) | P1 or P2 | SEC-authorized model and a prior check with the SEC; the installation is defined and declared by the licensed electrical installer |

Sources: [SEC, ITG RIC No. 9.1/2021](https://www.sec.cl/sitio-web/wp-content/uploads/2022/01/5-EXIGENCIAS-TECNICAS-DE-INSTALACIONES-FOTOVOLTAICAS-AISLADAS-ITG-V4.pdf) · [SEC, RGR No. 02/2024](https://www.sec.cl/sitio-web/wp-content/uploads/2025/01/RGR-N-02-2024-V11-destacada.pdf) · 2026-09-26

Modules with broken or cracked glass are neither sold nor repaired: RGR No. 02/2024 bans installing modules that show breaks or cracks.

## Can used panels be connected to the grid in Chile?

The SEC authorizes photovoltaic modules by brand and model, based on IEC 61215 and IEC 61730 certificates issued for the new product by accredited bodies (Exempt Resolution No. 32,427 of 2020; RGR No. 02/2024, §8). There is no authorization route for used or refurbished modules as such.

That is why every module we sell keeps its brand, model and original nameplate, and the report includes that data so the installer can check whether the model is authorized. The installation declared to the SEC is defined by the licensed electrical installer. We recommend checking with the SEC before connecting used modules to the grid.

Off-grid use is not free of requirements: ITG RIC No. 9.1 asks for the same certificates and model authorization. RGR No. 02/2024 also requires each module to have a visible, indelible nameplate (Voc, Vmp, Isc, Imp, Pmax and maximum system voltage), bypass diodes and IP65 protection. We check that the nameplate is legible and that the diodes work; your installer verifies the rest.

According to Chile’s Ministry of Energy, the country lacks technical standards and methods to assess the degradation, safety and performance of second-life panels, and its Circular Economy Roadmap for Energy 2026–2030 plans for the SEC and the Ministry of the Environment to address those gaps in 2026–2027.

## How much power does a solar panel lose over the years?

The most cited reference is a median degradation of 0.5% per year, calculated by NREL from about 2,000 measurements (Jordan and Kurtz). At that rate, a 10-year-old module would keep about 95% of its nameplate power (simple calculation). In practice modules differ widely: that is why we measure each one.

What studies say about the power of used modules

| Study | Sample | Result |
|---|---|---|
| NREL, Jordan and Kurtz (US, 2013) | About 2,000 degradation measurements | Median loss of 0.5% per year |
| ANU and CSIRO (Australia, 2024–2025) | 3,749 decommissioned modules of 160–370 W | 58.1% fit for a second life, with a median remaining service life of about 12 years; about 14% of those that passed I-V and EL failed the wet leakage test |
| UFSC (Brazil, 2023–2025) | 23-year-old polycrystalline modules | 68% fit for a second life; they kept 87–88% of nameplate power and lost about 0.4% per year in their second life |

## How are refurbished panels quoted and bought?

1. **Tell us what you need**Total power or number of modules, use (grid-connected or off-grid), delivery region and timing.
2. **We propose batches**Available batches of a single model, by grade and power band, with the test data sheet of every module.
3. **Written quote**Price, warranty, lead time and shipping terms. Before the sale we state in writing that these are used or reconditioned products (Chile’s Consumer Protection Law, Law No. 19,496, art. 14).
4. **Shipping**Undamaged modules travel as general freight, in their packaging and with nothing stacked on top.
5. **Delivery**You receive every module with its label, the test report and the written warranty.

The price depends on measured power and grade, model and technology, quantity and delivery location. We do not publish a price list because it changes with every batch: the price is confirmed in the quote. [Request your quote](https://ecobaterias.org/en/contacto.html?segmento=compra-paneles).

### How to receive and store the modules

- Lift each module with two people, holding it by the short side and never by the junction box.
- Store the modules packed, in a dry, flat place, protected from rain and sun, with nothing stacked on top.
- A module produces voltage under any light. It only stops when covered with an opaque material: cover it before handling its cables.

## Do you have decommissioned panels? This is how we refurbish them

If your plant is repowering, you are replacing rooftop modules or you keep modules as spares, we refurbish them and return them tested. For whole-plant projects see [solar plant repowering](https://ecobaterias.org/en/solar-plant-repowering.html); if you would rather not keep the modules, see [reuse of decommissioned panels](https://ecobaterias.org/en/reutilizacion-paneles-solares.html).

1. **Intake and registration**We record brand, model, serial number, nameplate data and the reason for removal. Disused or damaged modules are handled as hazardous waste unless declassified: we coordinate pickup with licensed hazardous-waste transport.
2. **Visual inspection**Under at least 1,000 lux we check the glass, backsheet (rear sheet), frame, junction box, burn marks and delamination. A module with broken or cracked glass goes straight to recycling.
3. **Electrical testing**Dry insulation test, bypass diode testing, an electroluminescence image and an I-V curve under a solar simulator, corrected to standard test conditions.
4. **Repair**We replace the junction box, bypass diodes, connectors or cables, and the frame when needed. These are mature repairs (TRL 9, the highest technology readiness level) according to IEA-PVPS.
5. **Retest**Every repaired module goes through the wet leakage test and the I-V curve again before it is graded.
6. **Grading and label**We assign grade P1, P2 or P3 and the 5 W power band, attach the measured-power label next to the original nameplate without covering it, and issue the report. Whatever does not qualify is recycled with a valorization certificate.

A 6-minute test per module, not counting repairs; 50–100 modules per day. This is laboratory capacity, not a committed lead time: the lead time for each batch is confirmed in the quote.

Pickup: according to Chile’s Ministry of Energy, a disused or damaged panel is handled as hazardous waste unless it is declassified under Supreme Decree (DS) 148. We coordinate pickup with licensed hazardous-waste transport, and the batch travels with the declaration document the waste generator issues in SIDREP, Chile’s national hazardous-waste declaration and tracking system (DS 148, art. 81). Undamaged panels that go back into service travel as general freight. The details are in [collection and transport of batteries and panels](https://ecobaterias.org/en/battery-solar-panel-collection-transport.html).

What can be fixed in a panel and what cannot

| Component or defect | Repairable? | Note |
|---|---|---|
| Junction box and bypass diode | Yes | Suncycle, cited by IEA-PVPS, reports about 90% success on recent modules and about 75% on heavily aged ones |
| Cables and connectors | Yes | Replaced with mating pairs from the same manufacturer: IEC 62852 evaluates pairs of the same type and manufacturer |
| Frame | Yes, in the workshop | The module must be removed |
| Cracked backsheet | Sometimes | Coating or adhesive sheet; not when the cracking comes with chemical degradation and delamination |
| Broken or cracked glass | No | The SEC bans installing modules with breaks or cracks; it goes to recycling |
| Delamination reaching the edge or burn marks | No | The IEC 61215 visual inspection rejects them; they go to recycling |

In modules repaired for a diode failure, power ended up between 93% and almost 100% of nameplate (IEA-PVPS T13-37:2026): that is why they are graded again after repair. Each repair is covered in detail under [solar panel repair](https://ecobaterias.org/en/solar-panel-repair.html).

## Which panels do we accept and which do we not?

Which modules go to refurbishment and sale and which go to recycling

## What warranty and documents do you get?

Refurbished modules come with a 1-year seller’s warranty, issued in writing with the batch.

Before the sale we state in writing that these are used or reconditioned products, as required by Law 19,496 (art. 14). If you buy as a consumer, the 6-month legal warranty also applies (Law 19,496, art. 21, as amended by Law 21,398). In business-to-business sales the contract governs.

- **For every module:** Measured-power label and test report
- **For every batch:** Written 1-year warranty and a statement that the product is used or reconditioned
- **If part of the batch is recycled:** Valorization certificate for Law 20,920

## Frequently asked questions

### Is it worth buying used solar panels?

It is worth it when you know how much power they deliver today. An untested used panel can have microcracks or insulation faults you cannot see. Ecobaterías sells refurbished panels with measured power, an electroluminescence image and an insulation test for every module, and with a 1-year seller’s warranty. To connect them to the grid, the model must be authorized by the SEC; we recommend checking with the SEC before connecting.

### How much is a used solar panel worth?

It depends on the measured power and grade, the model, the quantity and the delivery location. Ecobaterías does not publish a price list because prices change with every batch: we quote by power and quantity, and the price is confirmed in the quote. We reply within 48 business hours.

### How much power does a solar panel lose over the years?

According to NREL, the median degradation of photovoltaic modules is 0.5% per year, with wide differences between modules. In Brazil, 23-year-old polycrystalline modules kept 87–88% of their nameplate power. That is why Ecobaterías measures every module under a solar simulator and sells it by measured power, not nameplate power.

### What warranty does a refurbished panel have?

Ecobaterías refurbished panels come with a 1-year seller’s warranty, issued in writing. Before the sale we state in writing that they are used or reconditioned products (Chile’s Consumer Protection Law No. 19,496, art. 14). If you buy as a consumer, the 6-month legal warranty also applies; in business-to-business sales the contract governs.

### Where can I sell used solar panels?

If you have a batch removed from a plant or a rooftop, Ecobaterías tests it module by module and decides which modules are reused and which are recycled. See how it works in [reuse of decommissioned solar panels](https://ecobaterias.org/en/reutilizacion-paneles-solares.html). If you would rather keep the modules, we refurbish them and return them with a label and a report.

### Can used panels be used as a roof or carport?

Yes, mounted on a carport, shed or pergola structure designed for their weight and for local wind: a current 2.28 × 1.13 m module weighs about 32 kg. A qualified professional must design the structure. If the modules are connected to an electrical installation, SEC requirements apply, off-grid systems included.

### Can I connect used panels to the grid in Chile (SEC declaration)?

The SEC authorizes modules by brand and model, based on IEC 61215 and IEC 61730 certificates for the new product, and has no authorization route for used or refurbished modules. Every module we sell keeps its brand, model and nameplate. The installation declared to the SEC is defined by the licensed electrical installer; we recommend checking with the SEC before connecting to the grid.

### What is a refurbished solar panel?

It is a used module that was tested, repaired if needed and retested before being sold with a declared grade. At Ecobaterías the grade comes from the power measured under a solar simulator: P1 (85% or more of nameplate), P2 (80–85%) or P3 (70–80%). The module keeps its original brand, model and nameplate.
