[Mesh] Solar Wi-fi Repeater?

*I'm putting together a solar wi-fi repeater for peoplesopen. Does anyone have a number for average power consumption for the Ubiquiti NanoStaton loco M2? Know of any cheaper/better components? * *ItemCostSpecsBattery <https://www.amazon.com/dp/B0010Z4MDK/ref=psdc_389574011_t1_B018IU1XSQ>$1712V, 5A, 60WCharge controller <https://www.amazon.com/Y-SOLAR-Waterproof-Controller-Lead-acid-Discharging/dp/B00XTQ76WW/ref=sr_1_20?ie=UTF8&qid=1522631531&sr=8-20&keywords=solar+panel+with+charge+controller>$135A, 12V, 60W panel maxSolar Panel <https://www.amazon.com/Polycrystalline-Solar-Panel-Module-Charging/dp/B01IFJ73X4/ref=sr_1_7?ie=UTF8&qid=1522634307&sr=8-7&keywords=20w+solar+panel>$3820W, 20.5”x14.4”Wifi Repeater <https://www.amazon.com/dp/B00HXT8FFI/ref=psdc_1194486_t1_B00DCNRTAG>$45Datasheet <https://drive.google.com/open?id=1DfxWDUMRfWqSYGr9rSBUCFbibCPe-0vB>, Sales page <https://www.ubnt.com/airmax/nanostationm/>, 5.5W max power, Up to 24V DC inputTotal Cost including tax and shipping(17+13+38+45)*(1.1)+10 = $135Power AuditThe wifi repeater claims a “max power of 5.5W” I’m hoping that average power requirements are less than this?
