Part 3/9:
After considering various options, a 100-watt monocrystalline solar panel was identified. Despite plans for a portable panel, the costs proved prohibitive; a fixed panel at $58 emerged as a suitable alternative. Compatibility with the EcoFlow River 2 was confirmed through checks on voltage limits, leading to the addition of the solar panel to the cart. While the subtotal of the order was $297, the coupon and free shipping brought the total down to a pleasant $248.
