| This system at burning man mainly powered a 3.5 cubic fridge which draws about 750 watt hours a day. There was also a fairly small stereo, 80 watt projector light for the disco ball,coffee grinder, cordless tool charging, 4 strings of LED Xmas lights and a charging stationfor a projector trike. There was also the occasional people stopping by to charge their digital cameras and such. The battery bank consisted of 4-6volt 220 amp hour T105′s. Theoretically, there is 4000 watt hours of storage if drawn over 20 hours but they were always floating by 1 or 2 the next day anyway. |

Travel (150W) & Home (1.3KW) power
These photos show the solar systems we use at our “off the grid” home near Madrid NM. This system was designed and installed by a professional solar contractor, Positive Energy, in Santa Fe NM.
The camper we take to Burning Man has 2 – 75 watt panels wired in parallel to charge a single deep discharge battery. Next year we will add a second battery and bring a spare panel for a bit more power.
This is our home power center. 24V nominal comes in through a Solar Boost controller that efficiently delivers maximum power to the batteries. A trace inverter delivers 120 VAC up to 4KW. The power center controls power distribution between the panels, batteries and inverter.
This is the junction box between the 9 pairs of panels and the DC input buss. Each panel is separately fused.
20 deep discharge 6 volt golf cart batteries store about 24KWH of energy for nights and those few cloudy days.
Here are the 18 panels facing the sun. Each panel has a rating of 75watts at full sun so the total is about 1350 watts peak.
The frame for the panels allows for quarterly adjustment of the elevation angle to account for the varying sun angle.
