I first came across Texas Instruments BQ24074 while looking at Adafruit's Universal USB / DC / Solar LiPo charger, which replaced their earlier MCP73781-based charger. It's relatively inexpensive ($0.81) and has an input voltage of up to 10V. Unfortunately this chip was out of stock when I ordered my board for SMT assembly.

AI Customer ServiceSolar power charging involves using solar panels to convert sunlight into electrical energy. This energy then charges batteries, allowing you to power various devices like phones, laptops, or larger equipment. Most solar charging systems include a solar panel, a charge controller, and a rechargeable battery.
Solar or photovoltaics (PV) provide the convenience for battery charging, owing to the high available power density of 100 mW cm −2 in sunlight outdoors. Sustainable, clean energy has driven the development of advanced technologies such as battery-based electric vehicles, renewables, and smart grids.
Most solar charging systems include a solar panel, a charge controller, and a rechargeable battery. This setup is efficient and environmentally friendly. Charging batteries with solar power provides various advantages: Renewable Energy Source: Solar energy comes from the sun, making it inexhaustible and widely available.
You can charge the power bank via sunlight and then use it to power devices later. Integrated Solar Chargers: These come with built-in solar panels and batteries, allowing you to charge devices directly from the charger itself. They’re great for camping and outdoor activities. Wattage Output: Higher wattage leads to faster charging.
Insufficient Charging: If your battery doesn’t charge fully, check solar panel alignment. Ensure panels face optimal sunlight. Overheating Batteries: If your battery overheats, inspect the charge controller settings. Adjust settings to avoid overcharging. Battery Not Holding Charge: If your battery discharges quickly, inspect for short circuits.
Proper setup guarantees effective and sustainable charging at any time, utilizing the power of sunlight. Monitoring and maintaining your solar charging system ensures efficiency and longevity. Regular checks and care keep your batteries charged and functioning well. Regular Inspections: Check battery terminals for corrosion.
