42 hours autonomy:

The 180 amp hour silicone battery fully charged will give the system 42 hours of running time with no charge before the low voltage disconnect kicks in and shuts the system down. As solar panels have the ability to pickup UV rays on rainy and overcast days, the battery is getting charged even in the event of bad weather.

The 135 watt solar panel is specified for areas with a minimum of 5 peak sunlight hours, the 190 watt (2 x 95) solar panel configeration is for areas with a minimum of 4 peak sunlight hours (allowing for the shortest days of the year when peak sunlight hours are lowest). This also co-incides with the longest night (longest lamp run times).

The silicone battery operates to full efficiency with greater temperature extremes than lead gel and lead acid batteries.

The Orca solar street lighting, solar road lighting and solar park lighting system is proving to have many advantages over previous solar lighting options.
