With a solar panel input of up to 32V and an integrated battery charger for 6V-15V batteries, this module ensures efficient energy management. It features a PWM fan controller for optimal cooling, a low power sleep mode for energy savings, and 4 configurable IO pins for versatile connectivity. Perfect for DIY projects and sustainable tech applications. ## Description This is a daughter card(hat) for the Raspberry Pi that allows the Raspberry Pi to be powered from a solar panel and/or battery. When the solar panel's output power is low(clouds, night time) the system automatically switches to battery power. During peak output from the solar panel(sunny day) the battery is recharged. Product literature and firmware updates can be downloaded from the manufacturer's website. Note : Box includes mounting hardware and quick connecter terminals, solar panel and Raspberry Pi are not included. ## Features - Solar Panel Input Up to 32V, Battery 6V-15V - Integrated Battery Charger - PWM Fan Controller - Low power sleep mode with programmable wake up. - 4 IO Pins configurable as digital IO or Analog to Digital ## Images ![rpigear Raspberry Pi Solar Panel Module - Image 1](https://m.media-amazon.com/images/W/IMAGERENDERING_521856-T2/images/I/6102cF2nddL.jpg) ![rpigear Raspberry Pi Solar Panel Module - Image 2](https://m.media-amazon.com/images/W/IMAGERENDERING_521856-T2/images/I/61y0XWRDTtL.jpg) ![rpigear Raspberry Pi Solar Panel Module - Image 3](https://m.media-amazon.com/images/W/IMAGERENDERING_521856-T2/images/I/51gulvUdhbL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Space-saving, feature-rich, and easy to use *by E***S on Reviewed in the United States on September 30, 2021* I tested this HAT extensively in some pretty brutal conditions before writing this review. By brutal I mean temperature swings of 40F degrees reaching the max thermal limits of the hardware.What this pricey HAT offers over other solutions is space-savings and control. You will not find a smaller package that offers the ability to sleep the Pi and then wake it up based on any combination of: button, battery volts, solar volts, time, pin-shorting. That last one lets you wake up the Pi based on any external hardware you desire. Want to wake up the Pi using an SMS text message? Doable!β€”with other hardware.The ability to sleep the Pi and wake it up is crucial for remote outdoor applications where the system must survive on its own, with only the sun's energy to keep it going.Everything is well-documented and setup is an absolute breeze. CLI commands allow you to read the state of the battery or solar panel, initiate sleep, etc.Ironically, the one aspect of this Solar HAT that could use improvement is its solar charging. Oh it works!β€”but it's not MPPT, and the battery charger can only output up to 2A (at a user-defined voltage). The good news is that a separate DC/DC step down converter is used to power the Pi itself: 3A continuous and 4A peak. So the 2A sent to the battery is not consumed by the Pi (unless there's not enough wattage coming from the panel).Frankly, I find this dual step down design confusing and limiting. Imagine that you want to sleep the Pi during the day while the sun is out and the battery is charging, and only use the Pi at night. Well you've now "lost" the 3A (15W) from that second step down converter. It's not being used and is not helpful at all. In this case, it would be far better to have all the amps going directly to the battery, instead of 2A to the battery and 3A going nowhere.A better design would be a higher-amp step down converter to charge the battery, and a separate converter for powering the Pi from the battery. In other words, the Pi should always be powered from the battery, and the battery gets all the amps from the panel.It would also be nice if the RTC had a supercap or coin battery backup. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/79712380-rpigear-raspberry-pi-solar-panel-module](https://www.desertcart.pt/products/79712380-rpigear-raspberry-pi-solar-panel-module) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
