Bird Buddy can be upgraded to include a detachable solar panel that should be able to fully charge the feeder in three full days of sunlight. Depending on how much you use it, it could povide Bird Buddy with all the power it could ever need thanks to other incredible power optimisations.
Please note that orders placed are due for shipping in November 2021. Bird Buddy is one of the most successful crowdfunding projects and we are currently in the development phase. You'll be among the first to receive a product once it hits the market.
