But if it doesn't, figuring out your solar panel size is also pretty easy using Ohm's Law. The product listing for your solar panel should list how much current it can output ( e.g. ![]() This guide will cover the inclusion of a battery (and the power management board to charge it), but a battery isn't strictly necessary if you want to get technical. I live in sunny Florida, and it still isn't consistent enough here to do without it. Therefore, I recommend your solar setup include a battery. You don't want to run your Pi when it's cloudy or dark.The solar panel outputs exactly 5V, plus ample current.However, this would assume a lot of factors: Let's get technicalīecause I know some of you might be thinking this: technically speaking, you can power your Pi using a solar panel without needing a battery. Solar panel and batteryĪ solar panel and battery are connected to your power management board. This board will handle solar charging and monitoring of the battery, optionally performing a safe shutdown if power somehow gets too low-though this should never happen. A HAT or power management board is connected to your Pi 3, Pi Zero, or any other model of Pi. ![]() Here's a breakdown of how we'll do it: Power management board (HAT)ĭepending on what Pi project you're planning, you'll want one of the great HATs for the Raspberry Pi. And with the right solar panel and battery, your project can also run continuously, forever.īuilding a solar-powered Pi is a surprisingly easy task. Powering your Pi using solar power will allow you to build green Pi projects powered by the sun. This guide will show you how to power your Raspberry Pi using solar panels.
