Re: [AFMUG] Solar system rough cost

[Bill Prince]

We do about half the solar panels as Chuck, and we only really need 10 days on the batteries. We have sometimes done less on both of those and depending on the exact location. We are on the 37° parallel, and get no snow, and no really hot weather, so we are in a fairly ideal solar environment. I'm not sure exactly where you need this, but you must be somewhere around the 28° parallel? You should get a lot more sun, but you probably also get a lot of cloud activity. Your typically higher temperatures will derate your solar panels as their output decreases with heat. You're burning 3600 watt-hours per day. That's a tall order for a customer. I'm guessing this is a lot more than just internet access? bp <part15sbs{at}gmail{dot}com> On 10/5/2018 1:23 PM, ch...@wbmfg.com wrote: Is this Florida?   In Utah, off grid, snow on the panels, worst case.  No sun for two weeks this is what I have used that has been field proven.   20X load worth of panels 2 weeks of autonomy worth of batts.    I would say if you went 200 watts * 20 is 4000 watts of panel. So $2K for the panels.   200*24*14=67 kWh of batt * 10 cents = $6.7K for batts   You can get batts for as low as 6 cents per watt hour.  I used 20 cents there.  Batts may be as low as half that.  Even less if you don’t have to worry about snow etc.    So $10K in Utah. In Florida you do not need 2 weeks.  What is the longest interval of solid overcast? You also have longer days in the winter.   Bill Prince has some figures for no snow areas.    From: Paul McCall Sent: Friday, October 5, 2018 1:59 PM To: AnimalFarm Microwave Users Group Subject: [AFMUG] Solar system rough cost   We have not done solar systems before, but am looking at it for a customer.   Need 150watt sustained, so figure about 250 to cover ourselves.   Looks like we get about 5.5hours per day of “peak sun”.   Any rough idea on how much it would cost for a system to do this?     Paul, PDMNet -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
