Product Description
This is a 10 Watt Mono-crystalline Portable Waterproof Solar Panel in black color (very rare) aluminum frame to charge your 12V battery or to run your science projects. The rare black color frame looks very nice. It is in a factory new package and is 100% brand new. The solar panel is assembled by Suntech, one of the highest quality solar cell makers. It is also waterproof. The working voltage for charging is 18V. If you need to use it to charge a car battery, you may need a charge controller to prevent the battery from overcharging. Connections included: alligator battery clamps. There are three types of Solar Cells on the market. All our Solar chargers use the best - Mono-Crystalline Solar Cells. Amorphous or Dual Junction Solar Glass are the cheapest but are only 7% energy efficient and have 5 years service life. They are big and heavy. Poly-Crystalline have 25 plus years of service life under direct sunlight and are 13% efficient. Mono-Crystalline have 25 plus years service life and are up to 20% efficient. This is the same type used in solar car racing. This type of solar cell is now in a worldwide shortage because only a few companies can manufacture this solar cell.

Solar PV System Casa de Baja May 27, 2008
L. Anderson (Baja, Mexico)
1 out of 1 found this review helpful
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:
This setup has another 40W panel on tap for 100W by end of 2008, with another 40W panel before next Summer to conclude a 140W system. With 80% efficiency, that's about 670 Watt-hours per day...at 7.8 to 10.1 Amps [3.9 to 5.1% charge rate]. Goal is lighting, music, & occasional 26" 60W LCD using 15W DVD player & 25W 2.1 speakers for movies when surf is flat. [~700-800 Watt-Hours consumed per day]
