Welcome to the forums!
Data
- 30 LED bulbs at 10W each = 30 x 10 = 300 watts
- 6x 175W solar panels = 1 kW array
Question
- Do I need more panels
- Do I need more batteries
To answer this you need to know how long you'll run the lights. For example, if you run a 300W load for 4 hours, that's 4x300 = 1200 Wh.
To know how much power your array will generate, look up the
insolation in a table or use a program like
PVWatts.
Example: If insolation is 3, then the array will produce 3 x 1 kW array = 3 kWh per day on average.
To know if you have enough solar, compare the amount the array produces to the amount the lights consume
To know if you have enough battery, convert the batteries amp hours into watt-hours.
Example: A 125 Ah 12V battery at 50% depth of Discharge is 125 Ah x 12V x .50 = 750 usable watt hours.
Hope that helps! The FAQ index has a lot of math examples for different situations you might find useful.
