Location:
K55, Baja California, Mexico
Purpose:
Reduce dependence on buddy’s noisy & smelly gas generator during weekend trips to beach shack. Week of rest after every usage.
System [June 2008]:
-> 60W total [~3.5Amps]. Two 20W [18Vmp] panel & two 10W [18Vmp] panels of the same mono-crystalline construction. [16AWG]
-> Morningstar MPPT 15 Amp Charge Controller. [14AWG]
-> Two [2] new 12V ~100AH deep cycle batteries [parallel ~200AH, 1/0AWG]
-> 700W AC inverter [4AWG]
-> 3.5KW gas generator to 6Amp AC batt charger for extra charging capacity when needed
Current Load:
-> Three [3] 12V x 26W fluorescent fixtures
-> Two [2] 12V x 15W fluorescent fixtures
-> One [1] 12V x 11W fluorescent fixture
-> One [1] 12V x 13W fluorescent fixture
-> Yamaha 2.1 speakers, 25W
-> Dual-port 12V car cig lighter adapter for mobile phone/iPod chargers.
Notes:
Panels are fixed @ slight SW & angle of ~35° from horizontal due to wind concerns, more than output, but very close to local latitude of ~32°. I was at the Baja house when the winds started the raging fires in SoCAL [2007], it was bad.
Voltage reads 20-24+V @ 3.4-3.6 Amps pre-load between 10:00AM & 3:30PM in June. Current load is lighting- OFF & ON 3-4 hours per night. Usually only one or two is ON at any given time. Lights work very well, almost like normal house. iPod is self-powererd to Yamaha 25W 2.1 speakers on inverter for 2-6 hours during day. Currently, we must use generator for TV/movies/games.
Expansion:
Another 20W panel for 80W total went in Dec 2008- another 80W will conclude a 160W system. Goal is 3 to 4 times per month…lighting, music, & occasional 26″ 60W LCD using 15W DVD player & 25W 2.1 speakers for movies when surf is flat. [~700-800 Watt-Hours/day]
