At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

The Viessmann Vitovolt 300 M is a high-performance photovoltaic module that uses monocrystalline cells to maximize solar capture. This German-engineered panel guarantees stable and secure electricity generation in residential and commercial installations of a high technical standard. The cost of inaction in solar energy systems includes the premature degradation of generic modules and the loss of return on investment due to low efficiency. The Viessmann Vitovolt 300 M resolves these operational risks through an 80% linear performance warranty after 25 years of service.

Shingle Technology and Superior Thermal Efficiency

The Viessmann Vitovolt 300 M implements shingle cell technology to eliminate shading losses between cells. This architecture optimizes the module's active surface, reducing operating temperatures and increasing the service life of semiconductor components.

  • Maximum Yield per Surface Area: Surpasses market efficiency standards thanks to the elimination of conductive ribbons (busbars) visible on the cells.

  • High Mechanical Resistance: The reinforced anodized aluminum frame design withstands extreme snow loads and wind pressures beyond standard regulations.

  • Integral Architectural Aesthetics: The Black Frame finish offers a subtle and elegant visual integration, ideal for projects where aesthetics and technology must coexist.

  • Certified German Quality: Each unit undergoes rigorous inspection processes to guarantee the absence of micro-cracks and lamination defects before deployment.

Energy Robustness and IT/OT Protection

The architecture of the Viessmann Vitovolt 300 M is designed to be integrated into smart grids through high-connectivity inverters. Its passive electronics protect the system against hot spots and ensure supply continuity in adverse weather conditions.

  • High-Transmittance Glass: Safety glass with an anti-reflective treatment that minimizes solar reflection losses and resists large-diameter hail impacts.

  • IP67 Junction Box: Sealed system for maximum protection against dust and temporary immersion, ensuring corrosion-free electrical contacts for decades.

  • Multi-Inverter Compatibility: Optimized to work with Viessmann energy management systems and third-party microinverters for individualized IT monitoring.

  • Low Annual Degradation: P-type monocrystalline silicon technology minimizes the effects of Light Induced Degradation (LID) during the first year of exposure.

    The Viessmann Vitovolt 300 M is compatible with all mounting systems for pitched and flat roofs, and ground-mounted installations. It must be installed with structures that allow for rear ventilation of the module to optimize the temperature coefficient.

    TECHNICAL RESTRICTION: Do not install in areas with a risk of permanent immersion or direct contact with extreme saline atmospheres without additional protection. The module requires a minimum tilt of 10 degrees to ensure the self-cleaning effect of rain and prevent the accumulation of sediment.

    Frequently asked questions

    • What distinguishes the Vitovolt 300 M from a conventional solar panel? The Viessmann Vitovolt 300 M stands out for its Shingle technology and German seal of quality. Unlike generic panels, it offers positive power tolerance and far superior mechanical stability, ensuring that your installation will always produce what is promised.

    • Is this panel resistant to extreme weather conditions? Yes. The Viessmann Vitovolt 300 M is certified to withstand pressure loads of up to 5400 Pa (snow) and wind suction of 2400 Pa . Its high-security tempered glass protects the cells against hail and other severe environmental impacts.

    • How does this module manage partial shading from chimneys or clouds? Thanks to the parallel connection of its overlapping cells, the Viessmann Vitovolt 300 M maintains high production even when part of the panel is shaded. In traditional panels, a small shadow can cancel the production of an entire string of cells.
