The Yeti Solar LightPortal™ is a complete solar wall lighting system that includes its own 20W solar panel (with mounting bracket and 20ft of waterproof, UV resistant cable), battery, charge controller, and high-efficiency LED light. Additionally, the LightPortal™ comes with printed instructions, all necessary mounting hardware, a high-efficiency light diffuser (i.e. lampshade) a one-use packet of silicone sealant, and even an extra-long drill bit to make drilling a wire hole easier. This 12V direct current system is simple and safe enough to install yourself!

Applications
  • Home lighting (bright enough to read by)
  • Lighting for outbuildings, sheds and garages
  • Cabin Lighting
  • RV and Boat lighting
  • Emergency lighting (not connected to the power grid in any way)
  • Small grow lights

 

 

The Solar Panel 

Yeti Solar Panel 

Solar panels are a clean way to generate electricity, and use a widely abundant resource (sunlight).

Specifications: 20 Watts; tempered glass front; weather-resistant anodized aluminum frame; mounting hinges and bracket attached; 20 feet of waterproof, UV-resistant cable with click connects for quick installation.   

Dimensions: 20.5 inches by 13.8 inches by 1.2 inches

 

 

The Charge Controller

A charge controller charges and maintains the battery, and keeps the solar panel from overcharging it. Yeti Solar pre-installs it in the light fixture, with color coded click-connects to connect solar panel, battery, and (optional) exclamation light. 

Specifications: Charges using boost, equalize, and float stages; uses Pulse Width Modulation (PWM); green light indicates charging; low internal power consumption (<4 miliAmps).

 
 

The Battery

 
Lead-Acid Battery 

This lead-acid battery is maintenance free, and lasts for years. Be sure to recycle it if you replace it!
Specifications: 12V, 9 Amp-hours; Absorbed Glass Mat (AGM) deep cycle battery.

 

The Light Fixture

LED Lighting Fixture 

 

The light fixture holds the charge controller and the battery, mounts onto any wall, and provides light from LEDs. The LEDs used are the most efficient that are commercially available.  The diffuser (lamp shade) is a flexible sheet of polymer bent into an elegant shape inspired by Japanese paper lampshades. It provides soft and diffuse light.

Specifications:

Wear-resistant anodized aluminum frame. Diffuser (lamp shade) transmits 87% of the light (most glass or acrylic diffusers transmit only 40-60%), and provides 88% haze (light scattering to avoid 'hot spots'). LEDs provide about 125 lumens/Watt, with control circuitry (~10x more efficient than an incandescent bulb, ~2-3x more than a compact fluorescent). Switch selects Bright (~1600 lumen), power saving (~800 lumen), and off mode.

Dimensions:

(without diffuser) 7.3 inches tall, 7.1 inches wide (top), 4.3 inches wide (bottom), 3.3 inches deep.

 

Other Hardware

The LightPortal is shipped with all the odds-and ends (screws, wall anchors, silicone sealant etc.) that you will need to complete installation. It even includes an extra-long drillbit in case you need to run the cable through a wall. No last-minute trips to the hardware store needed!
