There are few things we can count on in the world today, but one of them is that the sun will come up every morning providing a source of energy. The sun is about 93 million miles away but it creates enough energy every minute to meet all of our energy needs. While it is not necessary to power your LED light with solar power- it is easy. You don’t even need to understand it. Here is the information you need to relay to the local solar supply store as it relates to a LGM LED light:
The numbers per bar are: 400 mA if powered by 24VDC direct, drawing 9.6 watts. When working with photovoltaic/battery setups, it is infinitely desirable to not use a power converter. Typical PV/battery setups are for homes which need 120 vac power. They design the setup to have PV panels, batteries, and a power inverter to change the 12-24VDC panel voltage to 120VAC house voltage. The inverter has at best a 60-70% efficiency meaning that you lose up to 40% of the power from your PV panels. An LED light from LED Grow Master runs on 24VDC. A power regulator is needed, because PV panels output from 22 volts in the shade, up to 70 volts in full sun. The voltage coming into the LED light must be regulated to no higher than 24.7VDC.
