Solar Panels draw energy from the sun and convert this energy into electricity to recharge the battery.
When choosing the solar panel that best matches the battery energiser, climatic conditions must be considered.
This is due to peak sunlight hours varying during different times of the year. Solar panels are at their
maximum effectiveness during peak sunlight hours. They do not supply a charge to the battery at night.
The panel chosen must be able to provide sufficient charge during the available peak sunlight hours to keep the battery charged for at least 24 hours. The average minimum sunlight hours in many places varies greatly. Due to this variance, panels of different wattages are needed in different locales. The chart below shows the recommended solar panels for the Stafix range of battery Energisers.
| Energiser | Recommended Battery |
Average Minimum Sunlight Hours | |||
| 2 | 3 | 4 | 5 | ||
| B 1.5 | 45 AH | 1x46 Watt Panel | 1x30 Watt Panel | 22 Watt Panel | 15 Watt Panel |
| B 3 | 75 AH | 2x30 Watt Panel | 1x46 Watt Panel | 30 Watt Panel | 22 Watt Panel |
| B 6 | 100 AH | 2x46 Watt Panel | 2x30 Watt Panel | 46 Watt Panel | 30 Watt Panel |
| B 12 | 2x120 AH | 3x46 Watt Panel | 3x46 Watt Panel | 2x46 Watt Panel | 2x46 Watt Panel |
Deep cycle batteries are recommended for use in combination with solar panels, as they are designed for repeated deep discharge/recharge which conventional wet cell automotive batteries are not. The larger the battery energiser, the larger the battery required.
The battery must have sufficient capacity to compensate for cloudy days and at night when the solar panel produces minimal or no charge.
