Solarstone's Warranty Conditions

Solarstone OÜ (hereafter referred to as Solarstone”) provides the limited warranty to purchasers (hereafter referred to as the “customer”) of Solarstone products (Solar Full Roof, Solar Tiled Roof and Solar Carport).

The terms of the limited warranty are as follows:

1. Limited Product Warranty – 10-Year Repair, Replacement or Refund Remedy
Subject to the Exclusions and Limitations in clause 3 herein, Solarstone warrants its PV modules (hereafter referred to as “modules”), including factory assembled glass, cells, films, frame, electric components, connection boxes, plugs and wires, if any, to be free from defects in materials and workmanship under normal application, operating conditions, use, installation, and maintenance, within a period of 10 years from the date of delivery to the end customers but not later than 6 months after delivery to the first purchaser from Solarstone, (hereafter referred to as the “warranty start date”).
If a module is found defective in material or workmanship, Solarstone will, at its sole discretion, repair or replace the module, or refund the purchase price of such defective module as paid by the customer within the above specified period according to the type of defect.
For clarification purpose: “material or workmanship defects” are defined per IEC 61215 Clause 7, IEC 61215 Clause 10.1 and IEC 61730 Clause 10.1 for visual defects, and per IEC 61215 entire Clause 10 for electrical and mechanical defects. Like all materials exposed to different environmental conditions, components of modules are subject to natural degradation (aging) and their appearance may change within the warranty period.
The options to repair or replace defective modules, or refund the purchase price are the only and exclusive remedies guaranteed under this Limited Warranty for PV Modules and shall not extend beyond the period of 10 years set forth here. Remedies will be performed directly to the end customer only. This Limited Warranty for PV Modules does not warrant a specific power output, which shall be exclusively covered under Clause 2 hereinafter (“Limited Peak Power Warranty – Limited Remedy”).

2. Limited Peak Power Warranty – Limited Remedy
Subject to the Exclusions and Limitations in clause 3 herein, Solarstone warrants that any module(s) exhibits a power output no less than 97% of the nominal peak power specified on the respective datasheet or module label at Standard Testing Conditions (STC, defined as: (a) light spectrum of AM 1.5, (b) an irradiation of 1000 W per m2 and (c) a cell temperature of 25 degrees Celsius at right angle irradiation.) within the first year from the date of delivery to the end customers but not later than 6 months after delivery to the first purchaser from Solarstone, (hereafter referred to as the “warranty start date”), or power output declining by no more than 0.7% per year of the nominal peak power. Consequently, at the end of the twenty-fifth year from the “warranty start date”, the modules will still produce a power output of at least 80.2% based on the stated nominal output. For the above such loss in power measured by Solarstone facility or the 3rd party testing institute recognized by both sides, it is determined by Solarstone (at its sole and absolute discretion) to be due to defects in material or workmanship, is eligible for claim under this Limited Warranty for PV Modules. Solarstone will remedy such loss in power by either providing additional modules to the customer to make up for such loss in power, or by repairing or replacing the defective modules at the discretion of Solarstone. The remedies set forth in this Clause 2 shall be the sole and exclusive remedies provided under the “Limited Peak Power Warranty – Limited Remedy”.
Caution: Any power measurement mentioned herein shall be carried out in accordance with IEC 60904 and subjected to - a power measurement uncertainty of ±3%.
