TrailNAV, an open-source solar-powered offline navigation device based on ESP32-C6 MCU and 2.7" e-paper display, was released in June 2026. It integrates NEO-M8N GPS and QMC5883L magnetometer for destination guidance and digital compass — fully off-grid, no cellular required. Fully open-source on GitHub, demonstrating embedded systems' potential for ultra-low-power outdoor navigation.

NB-IoT and LoRaWAN have become dominant connectivity technologies for solar GPS trackers, offering ultra-low power consumption and strong signal penetration. Solar panels are being further miniaturized for animal wearable trackers. 

GaAs possesses many outstanding properties and has a wide range of applications, which can be broadly classified into four major areas: RF (Radio Frequency), PHOTONICS, LED (Light Emitting Diode), and PV (Photovoltaic).

In an era of deep integration between the Internet of Things (IoT) and new energy technologies, solar-powered GPS suppliers are emerging as key drivers in advancing green positioning technology. By combining solar power generation with GPS positioning, these manufacturers offer sustainable, maintenance-free solutions for outdoor equipment, logistics tracking, environmental monitoring, and more.

To address the energy loss caused by insufficient sun-tracking accuracy in PV systems, researchers have developed a hybrid algorithm dual-axis solar tracking system (DASTS) that integrates GPS positioning and light-dependent resistors (LDRs). Through innovative LDR design and algorithm optimization, the tracking error has been reduced to 1.8°, and experimental results show a 38.2% increase in power generation compared to fixed systems.

The micro solar cell harvests energy from ambient light, but its output drops sharply indoors or at night. To solve this, the LED patch – which attaches comfortably to the skin – emits red light (670 nm) that penetrates deeply through tissue, delivering reliable optical power to the subcutaneous solar cell. This hybrid approach ensures continuous, daylight‑independent energy supply.

Micro solar cells have feasibility and potential applications in the field of wildlife localization and tracking, especially suitable for scenarios that require high endurance, device size, and environmental adaptability.

YIM SPACE provides a high-efficiency micro solar energy solution specifically designed for powering Internet of Things (IoT) devices. Utilizing Gallium Arsenide (GaAs) technology, YIM SPACE’s solar modules offer superior performance compared to traditional solar panel materials. These modules are compact, lightweight, and highly efficient, making them ideal for a wide range of IoT applications that require small form factors, low power consumption, and reliable energy sources.

Solar cells have become an essential component in aerospace satellite applications, providing a reliable and renewable source of energy. However, selecting the best solar cells for such applications can be a challenging task. There are various factors that need to be considered to ensure optimal per

Solar cells play a crucial role in the future of sustainable space exploration. As we venture further into the cosmos, powering our spacecraft and stations becomes a paramount concern. Traditional methods such as fossil fuels are not only impractical but also detrimental to the environment. Solar ce
