This is a mountain top (only about 6000 ft) radio repeater. This site will be a hike or snow mobile to it site in about 60 days and I need it to be much more self reliant. I have been there every 21 days for a couple of months for dead batteries, doubled battery capacity and it is obvious that wind alone is not going to keep power to it.

Thanks for the replies.

5 watt hours per hour 24 hours a day is correct, total 120 watt hours per 24 hours.

I was using 4 sun hours, located in Eastern Wyoming. We very seldom have overcast days and no wind. Jumping to 100 watts total of panels is not a huge amount more. That is my intention so;

Adding 2 more 100AH batteries and the solar panels. 100 * .8 = 80 * 2 = 160 even if the sun only shines for 2 hours + counting the deficit and there is no wind. I should be 100% reliable?

Thanks again.

I have a system that draws 5 WH per hour 24x7. I have wind power at the site but it has changed drasticly in the last year. New batteries, new generator. The Wind has days where it does not blow enough to charge the batteries some times 4 and 5 days straight. Once the batteries reach a critical level there is no recovery. I want to supplent the site with solar.

I forgot to add I have 2 105 AH deep cyles batteries in series for a 24 volt system. I have visted this site for a couple of days full days, the wind system is not going to work here due to the lack of wind.

I am looking at;
1ea - Morningstar Sunsaver Ss-10L 10A, 24V Pwm

2ea - Global Solar 30W 12V Framed Solar Panel

Is this enough to keep this site alive or is it overkill?
