Today I hooked up a single 100 watt panel and it was an overcast day.
At 9AM I decided to turn the heat on, I ran it for 20 min and checked the battery voltage, 12.2 while heat was running and back up to 12.5 after the heater shut off.
I then turned 3 interior lights (all LED's) on and checked after 2 hours, batteries @ 12.8 volts, still overcast.
Turned off the lights set thermostat to 60, batteries @ 13.1 volts.
Started to rain about 3 hours ago and it's 6:30 PM, heater still set @ 60, batteries @ 12.6 volts.
Again, I only ran a single 100 watt panel on an overcast day.
I'm excited to see what happens once I get all three 100 watt panels hooked up :C
