The August 2025 datasheet weight is 31.65 kg. No star rating is shown.
30-year linear power warranty. The datasheet prints up to 1.0% degradation in the first year and up to 0.4% a year after that, with 87.40% marked on the warranty chart. Product warranty period is set by Astronergy's limited warranty document for your batch. Ask SOLAR24 for the document that applies to your modules. The 23 March 2026 limited warranty applies to modules manufactured or supplied after that date. The document states a product-warranty period of 180 or 300 months, so a single year count is not shown here.
