Based on your request for a small solar panel for your computer backup system, I would recommend the GIZZU Solar Panel Kit 10W available for R999 or the Solar Mount Charger 2.0 available for R933.72. Both of these portable solar panels are compact and lightweight, making them ideal for charging devices on the go or as an emergency backup power source. The GIZZU kit in particular includes a USB port so you can directly charge devices like a laptop without needing additional cables. It's a great affordable option to keep your computer powered up during outages. Please let me know if you need any other details!
Based on your question about wanting something bigger than 10W for solar power, both the Honda EU22i and Yamaha EF3000ISE generators seem like great options. The Honda EU22i is a lightweight 2KVA inverter generator costing R27550. As an inverter generator, it runs very quietly and is suitable for backup power needs during outages or camping. The Yamaha EF3000ISE is a more powerful 3KVA inverter generator for R39999. It has the addition of key start for easy starting without pulling a cord. Both will provide significantly more power than a 10W solar panel alone and could charge devices and even run small appliances if needed. Let me know if you have any other questions!
