Hi Sarah, Thanks for taking the time to comment on your Nature Power Bayport Solar Lamp post light. Please reach out to us at cs@rdkproducts.com so we can assist in troubleshooting as the light should come on daily at sundown and last for the entire evening. As you can see with all the customer reviews, this is a high quality and popular model and perhaps you need us to send out some new rechargeable batteries for your unit. Once we speak to you, we can help determine this and would gladly send at no charge. We look forward to hearing from you. Nature Power Tech Support Team
