Solar solution for remote location sensing

I have an application were I need to collect one or two data points at a remote location (ie 1/8 to 1/4 mi) from my building. I can get the data over wireless but I don't want to have to trench a conduit all the way out there.

Has anyone used a solar w/ battery system for remote sites? I don't need a lot of power just enough to run a radio and instrument. Probably less than 2A 24VDC.

Look at Grundfos.

Elpro Wireless - check out the 905-U or 105-U.

I run these off a 20W solar panel, regulator and 24AH of battery capacity in areas that can get snowed up / get no sun for 2 weeks.

1 analog and 2 digitals in one direction only. But they do have other multi I/O bi directional models
