Warranty

Electrical equipment such as solar charge controllers and inverters have 1 year warranty, unless stated otherwise in our product description. Warranty for our own "Photonic Universe" branded products is provided by Photonic Universe Ltd. If we find any defects in our own products within the warranty period, we will repair or replace such products at our discretion free of charge. Warranty for other products is provided by the product manufacturer and terms and conditions of this warranty might be different from our terms and conditions. Full terms and conditions of the warranty can normally be found in the product manual.

Photonic Universe solar panels are covered by 1 year workmanship warranty in relation to assembly, materials and accessories (connection, cables, diodes, frame etc). In addition, there's a separate performance warranty on solar cells provided by solar cells manufacturers. Most manufacturers of solar cells we use for our solar panels provide the standard industry warranty, which is that solar cells are guaranteed to produce at least 90% of nominal power in 10 years and 80% of nominal power in 25 years.

If you suspect a product defect within the warranty period, please contact us by phone or email with a detailed description of the problem. If the problem cannot be solved remotely and an examination is required, you will be asked to send the item back to us for testing at your cost. If we are involved into repair / replacement of the product and the problem is covered by the warranty, we will return the repaired / replaced item to you at our cost. If the item you sent to us under warranty is in good working condition and no defect is found, it will incur a test service charge and the shipping cost to send the item back to you.
