Refund policy

TESUP proudly manufactures the world's most advanced household wind turbines and flexible solar panels. To meet the high demand for our cutting-edge products and ensure precision in craftsmanship, we deliver your goods within 3 to 4 weeks.

Every TESUP product undergoes meticulous assembly and rigorous testing to meet stringent quality standards before shipment. The testing process is documented through recorded videos, which are then sent to customers via email and stored in our archive for future reference.

Each TESUP product features custom-built software personalized with the customer's name. Please be aware that once an order is placed and processed, modifications to the software remotely are not possible, and consequently, we do not offer refunds.

To address concerns about the performance and energy yield of our wind turbines, accurate wind speed measurement is a must for benchmarking. We require customers to use a calibrated TESUP anemometer during the initial four weeks of product delivery. The TESUP anemometer is available as an optional tool for purchase on all TESUP web stores. For products under warranty experiencing manufacturing defects or malfunctions, customers must send them to our London repair center for examination. Our dedicated team handles repairs with precision, providing a comprehensive report for each case. While shipping costs for returns are the customer's responsibility, if the fault is attributed to the production process, these costs will be reimbursed. In such cases, a new replacement product with free delivery will be promptly sent.

We appreciate your understanding of these necessary procedures. Our commitment remains steadfast as we continue to deliver high-quality, innovative energy solutions.
