• Smartphones, tablets, and other small electronic devices.
• LED lights (camping lights, garden lights, security lights).
• Portable power banks and battery packs.
• Sensors and IoT devices (weather stations, animal trackers, smart home devices).
• Small pumps for fountains or aquariums.
• Vessel Monitoring Systems (VMS) and other marine electronics.
• DIY projects and educational kits.
• Trail cameras.

A: Consider the following:

• Device power consumption: Check the voltage and amperage (or wattage) of the device you want to power.
• Operating hours: How long do you need the device to run daily?
• Sunlight hours: How many hours of effective sunlight will your panel receive per day in its intended location?
• Battery capacity: The panel should be able to recharge your battery within a reasonable timeframe.

As a general rule, calculate your device’s daily energy consumption (Wh or Ah) and choose a panel that can generate at least 1.5 to 2 times that amount, accounting for inefficiencies and varying sunlight.

A: The best battery type depends on your specific needs:

• Lithium-ion (Li-ion): Lightweight, high energy density, good for portable applications, but can be more expensive.
• Lithium Iron Phosphate (LiFePO4): Excellent lifespan, safer than traditional Li-ion, good for deep cycling, but can be heavier.
• Sealed Lead-Acid (SLA) / AGM: More affordable, robust, but heavier and generally have a shorter cycle life than lithium batteries.

Always choose a battery with a suitable voltage (e.g., 3.7V, 5V, 12V) that matches your device and panel.
