How to Power a Security Camera Using Solar Panel: A Step-by-Step Guide

Most Wi-Fi-enabled security cameras consume 4–15 watts when recording. Some go into low-power standby mode when idle, while others continuously record at full power.

Example:

• Six Wyze Cam v3 units, each at 5W: 6 × 5W = 30W total
• Running 24 hours/day: 30W × 24h = 720 Wh/day

That’s your daily energy requirement. From here, you can calculate your battery size and solar panel wattage. For example, 144 Wh ÷ 12V = 12 Ah needed. Here, 'Ah' stands for 'amp hours,' which is a standard unit for measuring battery capacity.

Tips when assessing power requirements:

• Check manufacturer specs for voltage and current draw
• Add 20–30% margin for cloud cover and system inefficiencies
• Consider accessories like Wi-Fi extenders, which may draw extra power

Choosing the Right Battery

Your battery is the heart of the system. It ensures your outdoor security camera keeps running when the sun isn’t shining.

Battery Types:

1. AGM or Gel Lead Acid

• • Low cost, but heavy
  • Only use ~50% of capacity to preserve battery life

2. LiFePO₄ (Lithium Iron Phosphate)

• • Lightweight, long-lasting (up to 3× more cycles than lead acid)
  • Use up to 80–90% of capacity

For solar applications, a deep cycle battery is recommended because it is designed to be regularly discharged and recharged, making it ideal for powering security cameras.

Sizing Example:

If your camera uses 144 Wh/day at 12V:

144 Wh ÷ 12V = 12 Ah needed

For lead acid (50% usable): 24 Ah battery

For LiFePO₄ (80% usable): 15 Ah battery

Pro Tip: Size your battery for at least 2–3 days of autonomy in case of cloudy days.

Choosing the Right Solar Panels

The solar panel must produce enough daily energy to recharge the battery fully.

Factors to Consider:

• Wattage: Higher wattage = more energy per day
• Panel Type:
  • Monocrystalline = More efficient, performs better in low light
  • Polycrystalline = Lower cost, slightly less efficient
• Durability: Look for IP65+ rated panels for harsh conditions
• Mounting: Adjustable mounts maximize direct sunlight

If you need more power than a single panel can provide, you can create a solar array by connecting multiple panels together.

Sizing Formula:

Battery capacity (Wh) ÷ Peak sun hours = Minimum panel watts

Add 30% to compensate for system losses.

Example:

288 Wh ÷ 5 sun hours = 57.6W

57.6W × 1.3 = 75W solar panel recommended
