DESLOC V150Plus: World's First Perovskite Solar Smart Lock Nears $200K on Kickstarter

Campaign Launch and Brand Strategy

The V150Plus launched on Kickstarter on June 25, quickly approaching $200,000 in funding within its first day. This rapid success follows its official unveiling at CES 2026, where DESLOC also showcased two other new products: the K140Plus, featuring palm vein recognition, and the S150Max, with dual-camera doorbell monitoring. These three products form DESLOC's 2026 flagship lineup, with the V150Plus positioned as a mid-range offering. DESLOC, a brand from Desman with 17 years of experience in the smart lock industry, approaches this crowdfunding campaign differently from most first-time hardware projects. It represents a strategy for an established brand to validate new products in the market and reach early adopters through crowdfunding, rather than starting from scratch with product concept validation. This approach is increasingly common for traditional brands testing international markets, using one product to gauge market reception before scaling up operations.

Key Product Features

**4.8-inch Integrated Perovskite Solar Panel: Industry-First Low-Light Self-Charging**

Traditional solar smart locks have long suffered from a structural flaw: common crystalline silicon solar panels are ineffective in low-light conditions, such as under covered porches. This often means that many 'solar' locks still require battery changes every few months, frustrating users who prioritize convenience, security, and sustainability.

The V150Plus addresses this by embedding a high-efficiency perovskite module directly into the lock body, rather than relying on external polycrystalline silicon panels. Coupled with proprietary light-sensing energy management algorithms, which dynamically monitor ambient light intensity and battery status to optimize energy distribution, it achieves a truly maintenance-free, eco-friendly smart lock. The system begins charging with as little as 200 lux of illumination and maintains stable operation under typical conditions of 4000 lux.

This specification is directly designed for the US market. According to data from the National Association of Home Builders, over two-thirds of new single-family homes feature a porch. These porches are often brightly lit but rarely receive direct sunlight, precisely the scenario where traditional solar locks fail.

The degradation rate of perovskite materials under long-term outdoor exposure, high humidity, and temperature cycling remains a critical long-term reliability variable for this emerging photovoltaic technology when applied to consumer products.

**3D Facial Recognition + AIGPTfinger2.0 Curved Fingerprint Sensor**

The device features 3D facial recognition with liveness detection capabilities, effectively preventing spoofing attacks using photos or videos. It also incorporates the GPTfinger2.0 curved fingerprint sensor, engineered for rapid and precise identification.

This curved capacitive fingerprint sensor conforms to the natural arc of a finger, offering more reliable recognition for shallow, worn, dry, or moist fingerprints compared to traditional flat sensors, with an unlock speed as fast as 0.15 seconds. The combination of multiple biometric methods (face + fingerprint) provides users with flexible unlocking options, and liveness detection offers substantial security value against common photo-based impersonation attempts. The actual recognition accuracy and false acceptance rates of fingerprint identification under various finger conditions are common areas where user experience can vary significantly in biometric smart lock reviews.

**Removable 10,000mAh Backup Battery: Dual Power Supply for Uninterrupted Operation**

In addition to continuous solar recharging, the device is equipped with a removable 10,000mAh backup battery unit.

This ensures uninterrupted operation even if solar power is insufficient.

The dual-track power design, combining solar and traditional battery, essentially positions perovskite solar as an auxiliary energy source to extend battery life and reduce replacement frequency, rather than a complete battery replacement. This represents a more realistic and robust engineering compromise, preventing users from facing power outage risks in extreme low-light seasons (e.g., high-latitude winters) with a purely solar solution. Official estimates suggest this approach can reduce the consumption and disposal of up to 146 disposable batteries annually, offering additional appeal to environmentally conscious users. The practical ease of removing and replacing the backup battery is a detailed consideration for daily user experience.

Advanced Security and Power Management

**IP65 Waterproof + ANSI/BHMA Grade 3 Certified + All-Weather Temperature Testing**

The V150Plus inherits core features from its sibling, the K140Plus, including touch-based unlocking, built-in Wi-Fi, app remote control, and voice assistant support. It boasts an IP65 waterproof rating and complies with the ANSI/BHMA Grade 3 standard.

The product has undergone all-weather extreme temperature testing, with an operating temperature range covering -22°F to 158°F, designed for real-world front door conditions across all seasons.

It's important to note that Grade 3 is the lowest rating in the ANSI system (residential locks typically use the BHMA rating system, which is related to but independent of commercial locks). While it sits at the lower end of the rating scale, commercial-grade locks are generally more robust than residential products. This certification at least provides a comparable objective security benchmark, rather than purely marketing claims.

**Energy Dashboard App + Easy DIY Installation, No Monthly Subscription**

The accompanying DESLOC App provides an energy dashboard, clearly displaying battery level and charging status. This transforms the previously invisible and ambiguous issue of lock power into visual, trackable data. The product supports easy DIY installation, includes full app control functionality from day one, and does not charge any monthly fees. The no-subscription model differentiates it from the service fee models increasingly popular with some smart home security products, representing a more consumer-friendly pricing strategy. The energy visualization dashboard addresses a major psychological pain point for users of solar-powered devices: 'How do I know if it's actually charging?' This transparency design directly reinforces the product's core value proposition of being maintenance-free.

Global Smart Lock Market and Competitive Landscape

The global smart lock market is experiencing continuous high-speed expansion. While specific figures from different research institutions vary due to differing methodologies, the growth direction is highly consistent: multiple reports indicate a global market size between $1.5 billion and $4.9 billion in 2024, with a projected CAGR generally ranging from 12% to 20% between 2030 and 2035. By 2032-2035, the market size is expected to reach anywhere from $7.6 billion to $17.1 billion. Regionally, North America leads the global market in 2024 with approximately 37.7% to 40% share, while the Asia-Pacific region is projected to catch up with the fastest growth rate. Key growth drivers include the continued penetration of smart home ecosystems, the maturation of interoperability standards like Matter and Thread reducing device binding barriers, increased consumer security awareness, and declining costs of biometric sensors driving features down to more mainstream price points. Within authentication methods, biometrics are expected to be the fastest-growing sub-segment, with an estimated CAGR of around 17.7%, which aligns with the V150Plus's key focus.

In terms of competitive landscape, ASSA ABLOY (with brands like Yale, August), Allegion (Schlage), Spectrum Brands (Kwikset, Weiser), Samsung SDS, and Honeywell are major leading brands in the global smart lock market. These companies build barriers through established retail channels, brand trust, and deep integration with mainstream smart home platforms (Alexa, Google Home, SmartThings). In 2024, these top manufacturers collectively held approximately 70% to 75% of the global market share. In the niche segment of solar smart locks, previous market offerings generally relied on external polycrystalline silicon panel solutions, which had limited efficiency and applicability. The DESLOC V150Plus, with its perovskite material and integrated embedded design, currently has no direct mature competitors for its specific low-light self-charging functionality, establishing a clear differentiated position. The main market risks are: long-term reliability data for perovskite solar technology in consumer-grade outdoor products is still limited, and the industry as a whole is still in the early stages of moving from laboratory to large-scale commercialization. Simultaneously, if leading smart lock brands determine this technological path has commercial value, they could quickly follow suit due to their stronger supply chain scale and channel coverage capabilities. DESLOC's ability to establish sufficient brand recognition and patent barriers within this window will determine how long this industry-first advantage can be maintained.
