6. 2 core wire – $16

Shipping cost for those from overseas amount to around $50.

Total cost for project is $356, big chunk of it is Battery and LED Strip.
If the charging really work

I’ve about 2 hours of direct sunlight on the Solar Panel at this time of the year.
A good iPhone App, EPiSunTools, helps show how much Sunlight I’m going to get for me installation.
I got worst coverage at this time of the year, so if this setup works now, it’ll work for the rest of the year.

The 100W unicell Solar Panel is value for money, about $100 inclusive of shipment. Complete with ??4 connectors which are IP65 certified.
Panel is rated ????
During morning sun (8+am) I’m getting 2.2A Isc 20V Vsc with direct sunlight.
Without direct sunlight, I’m seeign 0.3A Isc 19.2V Vsc, not sure is this normal.

On connection to the battery through the Charge Regulator, I measure 13.5V across both the SolarPanel Battery, which is the floating voltage. Will need to monitor how the whole system runs over the week.
