Solar power spotlights with night sensor

Featured Replies

Afternoon all,

I am looking at putting up 4 x 20w spotlights around the house. The lights are to last for 12hours during the night.

What would be the easiest?

 

Buying 4 individual lights with 4 30w solar panels and individual batteries, or just buying 1 panel , inverter and battery? Which one would be the cheaper option.

 

Not looking at going off Grid just yet.

 

Your assistance would be appreciated

Hi Shaun

I have done exactly this but was very luck in that I got all the floods onto one circuit.  If you are able then one small inverter/panel/battery is easiest to manage.

Otherwise you get solar floodlight units that have everything combined and run off 12V.  Alot of solar streetlights are designed this way.

Regards

Mark

I'm lucky I have all lights and therefore my floodlights circuit on an Axpert 5kv inverter already.  So 5x 10w LED floods is a small part of my load.

Have a look at an old post of mine. I made a 6w LED flood light that's 12v by using old casings and retrofitting LED strips inside. Total cost on these for everything was about R50 each. Distance of about 15-20m for each one easy. I actually made 2 this weekend that use 360lm 1.5watt units. 

1 battery, 1 solar controller, 1 solar panel.
