# Battery and Solar Panel Technical Service | Ecobaterías > Technical service in Chile for lithium-ion batteries and solar modules: testing, repair, second life and recycling with a certificate for the EPR law. Canonical: https://ecobaterias.org/en/servicios.html · Language: en · Alternate (es): https://ecobaterias.org/servicios.html · Updated: 2026-09-18 Technical service # Diagnostics, repair and reuse of batteries and solar panels Before recycling, we measure. One technical service decides, with objective tests, the best destination for every lithium-ion battery and every photovoltaic module: repair, reuse or recycle, with traceability and a certificate for Chile’s EPR law (Ley REP, Law No. 20,920). Updated on September 18, 2026 · Reviewed by the Ecobaterías technical team [Request a diagnostic](https://ecobaterias.org/en/contacto.html?segmento=servicio-tecnico)[Message us on WhatsApp](https://wa.me/56940118111?text=Hi%2C%20I%27d%20like%20a%20quote%20for%20your%20technical%20service%20%28testing%2Frepair%29.%20What%20I%20have%3A%20) - **1,100 t** — of lithium-ion battery waste estimated for 2026 in Chile - **6 min** — of testing per photovoltaic module on our line - **30 min–6 h** — of diagnostics per battery pack, depending on the test Sources: [Impact assessment of the draft battery decree, Ministry of the Environment (Res.

Every unit goes through a test protocol that sorts it into one of four routes: direct reuse, refurbishment, second life or recycling. - **What we receive:** Electric vehicle and bus batteries, BESS, machinery and micromobility; photovoltaic modules - **Where:** Santiago, Chile · coordinated pickup nationwide - **Diagnostic time:** Battery: 30 min to 6 h per pack · PV module: 6 min - **Output:** Per-unit report, certificate and valorization route - **Legal framework:** Law 20,920 (Ley REP), Supreme Decree (DS) 148/2003, DS 22/2025 - **Reference standards:** IEC 63330-1, UL 1974, IEC 61215, IEC 61730 ## One logic: measure first, then decide Chile’s Extended Producer Responsibility law (Ley REP, Law No. 20,920) ranks waste management by hierarchy: preparation for reuse first, recycling second. Ecobaterías applies that hierarchy with data. Batteries and modules that arrive do not go straight to grinding: they are tested and, if they hold value, they return to the market with a certificate. Only what fails the tests is recycled, and even then the materials are recovered inside Chile. ## The four routes of a battery or a module ### Direct reuse SOH ≥ 90%, withdrawn because the equipment became obsolete: state-of-health certificate, label with measured values and resale or reinstallation as a spare. ### Refurbishment and return to service SOH ≥ 80% and no safety faults: the weak module is replaced with a matched one, plus BMS, contactors, fuses and sensors; balancing and retest with warranty. ### Stationary second life SOH 65–80%: modules graded and matched for low-power storage, backup, solar self-consumption, remote sites and social projects. ### Recycling at our own plant SOH < 65%, high internal resistance, safety fault or no data: regenerative discharge, dismantling and cells to our hydrometallurgical plant in Santiago. Source: Ecobaterías test protocol · in-house thresholds, not a standard · 2026-09-18 ## Status of each service line - **Battery intake and recycling:** In operation - **Battery diagnostics and repair:** 2026–2027 pilot program (limited capacity) - **PV module line:** 2026–2027 pilot program (limited capacity) - **Stationary second life:** 2026–2027 pilot program (limited capacity) Status reviewed on September 18, 2026. The pilot program works with limited batches and case-by-case lead times: we do not commit industrial capacity on lines that are not yet in full operation. ## The test protocol, step by step 1. **Intake, registration and quarantine**Every unit enters with a unique code, weighing and visual inspection. Batteries with mechanical damage, swelling or a thermal event are isolated in a quarantine container with gas detection and a thermal camera. 2. **Data readout and electrical safety**Batteries: CAN or UDS connection to the BMS, insulation, per-cell voltage and internal resistance. PV modules: insulation at 1,000 V, frame continuity and bypass diode testing. 3. **Performance testing**Batteries: charge and discharge with regenerative equipment, incremental capacity analysis and impedance spectroscopy. Modules: electroluminescence in a dark cabin and an I-V curve under a solar simulator with a calibrated reference. 4. **Route decision and certification**Classification into routes A, B, C or D; repair and retest where applicable; per-unit report, certificate with the measured values and entry in the batch traceability record. 5. **Valorization or recycling with a certificate**Units that pass return to the market with a label and warranty. What fails the test is recycled: cells to our hydrometallurgical plant in Santiago and the rest to licensed recycling, with a valorization certificate for Law 20,920 reporting. ## Lithium battery technical service For electric bus fleets, BESS operators, EV dealers, insurers, mining and micromobility. We read the BMS, measure insulation, internal resistance and capacity, and decide whether the battery returns to the fleet repaired, becomes second-life storage or is recycled. [See the lithium battery diagnostics and repair protocol](https://ecobaterias.org/en/diagnostico-baterias-litio.html). ## Photovoltaic module line For PV plants being repowered or decommissioned, O&M companies, EPCs with construction breakage, insurers and rooftop owners. Inspection, electrical safety, electroluminescence and an I-V curve under a solar simulator; suitable modules are sold with measured power and warranty, repairable ones are repaired and the rest is recycled.

Repairing returns it to its original use by replacing modules or electronics; reuse (second life) puts its modules in a less demanding application, such as stationary storage; recycling recovers its materials. Chile’s Extended Producer Responsibility law (Ley REP, Law No. 20,920) puts reuse before recycling, and Ecobaterías decides with tests which one applies. ### Does the diagnostic have a cost? Yes, it is quoted per unit or per fleet contract. In many cases the value of the recovered battery or module exceeds the cost of the test, and the diagnostic avoids paying final disposal for units that still work. ### Do you receive batteries and panels from all of Chile? Yes. We coordinate pickup with licensed hazardous-waste transport (class 9), or shipment as product when the unit has not been declared waste. For northern sites we offer on-site mobile testing so the batch is sorted before it travels. ### What does it cost to hand over lithium-ion batteries for recycling? Intake for recycling is charged at 22 UF per tonne plus VAT (19%). The UF is Chile’s inflation-indexed accounting unit, published daily by the Central Bank, so the amount is calculated with the UF value on the invoice date. Pickup, transport and packaging are quoted separately. We do not buy lithium batteries: the material value does not cover the cost of the process. ### Can a refurbished panel or battery be grid-connected in Chile? Grid-connected systems require products certified by the SEC, Chile’s electricity and fuels regulator. Ecobaterías works only with models that keep their original certification and delivers a per-unit report. Until Chile has a protocol for refurbished products, second life targets off-grid applications, agriculture, backup and social projects. ### How fast do you reply? We reply within 48 business hours with the proposed route and the scope of the test. Pickup and testing lead times are agreed per batch. ## Sources - Law 20,920 establishing the framework for waste management and extended producer responsibility.
