These Terms and Conditions apply to all sales, contracts and services provided to CUSTOMERS by YOFI SUN, S.L., trading as PV Partner Iberia (hereinafter the SELLER) for orders placed online on www.pv-partner.com, by email or in a physical store. These conditions prevail over any others. YOFI SUN, S.L. reserves the right to amend them, always in writing, without the CUSTOMER's agreement. Placing an order constitutes the CUSTOMER's acceptance of these Terms and Conditions.

The terms of sale are Incoterms 2000: EXW. The registered office of YOFI SUN, S.L. is at Paseo General Martínez Campos 49, Planta 6, 28010 Madrid, Spain.

Orders must be placed by email or through the online store and are only binding once accepted in writing by the SELLER, through a written confirmation sent by one of the means of communication indicated. After receiving the order confirmation, the CUSTOMER must check it and inform the SELLER in writing of any errors within 24 hours. Otherwise, the product description and technical specifications stated in the SELLER's order confirmation are deemed correct and the order is confirmed.

Quotations and price offers are only valid when detailed in writing and for the period expressly stated in them. If no period is specified, a maximum of 3 days applies, with no possibility of extension. The product price and the payment terms are set out in each order confirmation. Prices do not include taxes, fees, insurance, installation or other additional costs arising from the delivery of the products, which are borne by the CUSTOMER unless expressly agreed otherwise in writing in the order. If, for reasons beyond the SELLER's control, such as changes in exchange rates, tariffs, insurance or other production costs (including components and services), a price change becomes necessary, the SELLER reserves the right to modify the price.

Payment must be made when the order is placed or, where applicable, as set out in the conditions of the order confirmation. The SELLER may suspend delivery of goods or services until the full amount has been paid. In the event of late payment, all additional costs are added to the final amount and late-payment interest of 1% per month on the outstanding balance is charged to the CUSTOMER, from the due date until full settlement.

Before shipping goods or providing a service, the SELLER reserves the right to verify the approval of the means of payment by the relevant entities, for as long as necessary. In the event of total or partial non-payment on the agreed due date, the SELLER may suspend or cancel any pending shipment or contract without incurring any liability for damage or loss, including loss of profit or damage caused by delays or loss of production. Under no circumstances does this power release the CUSTOMER from its contractual obligations regarding payments due and the receipt of products.

If the CUSTOMER resides outside the European Community and wishes to benefit from tax exemption, it must send the SELLER a copy of the invoice and proof of residence abroad after receiving the order. Once the invoice has been presented to Customs, the CUSTOMER must send it together with its bank details so that the tax can be refunded.

Goods are delivered to the CUSTOMER within the period and at the place specified in the order confirmation. Deliveries may be made in parts. Delivery is deemed to have taken place when the SELLER makes the products available to the CUSTOMER.

The CUSTOMER is responsible for checking the condition of the products on receipt and recording on the delivery document any justified remarks or damage claims (see Delivery Conditions). If delivery is refused without the SELLER's approval, all resulting costs and damage are borne by the CUSTOMER. The CUSTOMER is not entitled to claim for missing products or visible damage unless such remarks are recorded on the transport document or delivery note and notified in writing within 24 hours of their occurrence.

The CUSTOMER must ensure that unloading equipment is available and that the delivery address is suitable for unloading the order. The SELLER is not responsible for a lack of unloading equipment or an unsuitable unloading area at the chosen location. If the goods are not accepted within the delivery period, the SELLER is entitled to charge the CUSTOMER storage and redelivery costs.

The SELLER is not liable for failure to perform its obligations in unforeseeable or unavoidable situations or in circumstances beyond its control (force majeure or fortuitous events), including but not limited to government acts, strikes, lockouts, civil unrest, earthquakes, natural disasters, shortages of raw materials, supplies or equipment, and failure of facilities.

Goods supplied remain the property of the SELLER until the full price has been paid, even if direct possession has already passed to the CUSTOMER. Until full payment, the CUSTOMER may not pledge or assign these goods to third parties as security, whether real or personal, must keep the goods in good condition and, where applicable, identify them as the property of YOFI SUN, S.L. Exercising the retention of title does not imply waiving the right to demand performance of the contract or compensation for damage.

The CUSTOMER must examine the products immediately after delivery and has 24 hours to inspect them and report any defects or damage resulting from delivery. After this period, the delivery is deemed accepted without reservation by the CUSTOMER, the SELLER is not liable for any damage and the CUSTOMER loses any right to claim for it. If a product has to be returned for justified reasons and the SELLER has been informed, the goods must be returned in their original condition, with their packaging, a return note and proof of purchase. Return costs are borne by the CUSTOMER unless the return is justified under the product warranty included in the package.

The CUSTOMER may request the return of a product within 10 days of receipt, in accordance with the right of withdrawal provided for in the applicable legislation.

For a return to be accepted, the product must be in its original packaging, with no signs of use, damage or alteration, and accompanied by all accessories, manuals and documents sent.

The CUSTOMER must contact customer service by email at [email protected], stating the order number and the reason for the return. After the request, instructions for shipping the product are provided. Shipping costs may be borne by the CUSTOMER, except in cases of a defect or an error in the order.

If the return meets all the above conditions, a credit note will be issued to be deducted from a future purchase.

The CUSTOMER shall use the goods in accordance with the manufacturer's manual and instructions for use. The SELLER is therefore not liable for any damage to property or third parties caused by incorrect handling or failure to follow the instructions in the user manual or the product safety standards. The SELLER is not responsible for incorrect installation or product failure. If a product supplied proves defective during the warranty period set by the manufacturer, the SELLER will assist with all necessary communication with the supplier or manufacturer for repair or replacement within a reasonable period. The CUSTOMER shall allow the SELLER, or third parties designated exclusively by it, to examine the product at its location or at the premises indicated. The SELLER will give the necessary attention to resolving problems within an appropriate period in the circumstances.

The SELLER does not guarantee and is not responsible for:

  • damage caused by improper installation, use, modification or repair by unauthorised third parties or by the CUSTOMER;
  • damage caused by any person or other external force;
  • suitability of the product for a specific purpose or use other than the intended one;
  • lack of response or attention from the product supplier or manufacturer;
  • transport or repair costs invoiced by the manufacturer or supplier.

The SELLER's liability for any breach of this warranty, its service commitments or for any other reason shall in no case exceed the product price stated in the order confirmation. The warranty covers only labour and defective parts, thereby limiting the SELLER's liability. It does not cover the replacement of consumables, abnormal use of the products, faults in accessories, damage from causes external to the device, or deterioration caused by adaptations or adjustments. The warranty is void if the product's serial number has been modified; in the event of shocks, accidents and/or improper transport; handling by personnel other than the technical service recommended by the manufacturer and the SELLER; tampering with any seal or identification or control label; normal wear and tear; or damage due to natural phenomena or disasters, such as storms, floods, lightning, earthquakes or fires; or insolvency of the product supplier or manufacturer.

Warranty procedure

Before sending any material, the CUSTOMER must contact the SELLER. A claim is not accepted without a number assigned before shipment; otherwise the material is returned to the CUSTOMER and the transport cost is charged. To open a claim, the CUSTOMER must send an email to [email protected] with:

  • product reference
  • product serial number
  • invoice number
  • detailed description of the fault or item to be repaired
  • shipping address for the repaired product, if different from the billing address

Once the process is complete, the CUSTOMER receives an email explaining how to return the material. Shipping costs are borne by the CUSTOMER, who is responsible for any damage or loss arising from transport of the product.

Where services to be provided by the SELLER are agreed, estimated response times are indicative and may vary depending on the location or accessibility of the product. The service may be provided by phone or online, depending on its characteristics and circumstances. If agreed and stated in the order confirmation, the service offer may include advice and training on the product(s).

Unless expressly provided for in the order confirmation, the service does not include: items excluded from the warranty, configuration changes, repositioning, preventive maintenance, work that the SELLER considers unnecessary, or issues related to the electrical environment.

The product may include technology and software subject to the applicable export control laws of the USA and/or the country where the product is delivered or used, and the CUSTOMER must comply with these laws. The product may not be sold, leased or transferred to end users or countries subject to such laws, or to users involved in weapons of mass destruction or genocide. US restrictions may change frequently depending on the product, so the applicable US regulations must be consulted in each specific case. Having given this notice, the SELLER is exempt from any liability, and the end CUSTOMER is solely responsible for any resulting event and any damage that may arise.

The SELLER is not liable for delays (including deliveries or services) resulting from circumstances beyond its reasonable control, and the period for performing those obligations is extended accordingly. This includes, but is not limited to, strikes, transport, supply or production problems, exchange rate fluctuations, government action and natural disasters. If the force majeure event lasts more than two (2) months, either party may terminate this contract without any right to compensation.

The parties shall treat all information and documents received or issued by any means and relating, directly or indirectly, to this transaction as confidential, and may not use them for any purpose other than the fulfilment of the subject matter of this contract.

YOFI SUN, S.L. may terminate this contract by prior written notice for any of the causes established in the Spanish Civil Code, and if: (1) the price is not paid on time, the parties expressly agreeing that total or partial non-payment results in automatic termination of the contract without any claim by the defaulting party; or (2) the CUSTOMER breaches, or YOFI SUN, S.L. suspects that the CUSTOMER has breached, export control laws. Either party may terminate this contract if the other: (1) materially and persistently breaches this contract and fails to remedy the breach within 30 days of being requested in writing to do so; or (2) is declared in judicial reorganisation or bankruptcy or is unable to pay its debts when due. A party that has faithfully performed its obligations as agreed may choose to demand performance of the other party's obligations or to request termination of the agreement and claim compensation.

The CUSTOMER's main obligation is to pay the price of the product and/or associated services in accordance with the agreed terms and conditions.

The CUSTOMER is responsible for the product and its suitability for the specific intended purpose, and bears its own telephone and postal costs, where applicable, for contacting the SELLER. The CUSTOMER shall treat our staff with due courtesy, conduct itself as a diligent merchant as established in the Commercial Code, provide all necessary information and cooperate with the SELLER so that it can faithfully fulfil its commitments.
