RE: mono vs poly real life testing

3 tons, I don't see it as perplexing. The 100 watt poly is physically larger which we all knew. The output when covered is higher from poly. The output in haze is higher from poly. The difference in size is not great. The difference in output is higher with poly. The cost is lower with poly. So, if I were to redo my system I would move to poly. And if I were starting from scratch, I would use poly. The only time mono might be better is if there were perfect solar conditions. But that option was not tested.

RE: mono vs poly real life testing

3 tons, The 2 mono and 2 poly were all rated at 100 watts. The poly's out performed the mono's in all the tests. How does that make the results "ring hollow"?????

RE: mono vs poly real life testing

red31, What Vintage465 is saying is that he was ripped off. Panels are often priced below $1 per watt and that has been so for many years now.

RE: mono vs poly real life testing

Red, they all rated 100 watts. Poly is supposed to be more efficient. Mono needs three more cells to “make” 100 watts. Test didn’t show more efficiency. But it does show more output in watts from poly vs mono unnder all the tested conditions.

RE: mono vs poly real life testing

“ The mono is better for RV use. Mono should be more efficient. In reality there is minimal difference, but I spring a few bucks extra always for the mono.” Agreed, but this additional efficiency manifest itself via a smaller footprint - regardless of which substrate, 100w is still 100w, thus I find the panel presenter’s conclusions a bit lacking... That is the exact opposite of what the testing shows. Poly works better except when solar conditions are perfect. Since he did not test in ideal conditions, we have no way of knowing if mono would truly outperform poly. The first "hints" of this were published on rvnet a lot of years ago when someone by chance bought two panels, one poly and one mono. The poly out performed in real life conditions. And yes the poly are always larger.

mono vs poly real life testing

Hi folks, This popped up and I thought it worth posting! https://www.youtube.com/watch?v=dZ_jrSAk-DU

RE: setting up a battery bank

To summarize, I want a reliable battery bank that will last for the day with modest use of the camper. I want to run a 1000 watt inverter off the same batteries to occasionally run small appliances and electronics. Finally, I don't want to run my 2000w generator more than an hour to charge the system back up after a day's use. I hope this all makes sense. Do an energy audit. Unfortunately lead acid wants to be charged to 100% full on as many cycles as possible. Running a generator to get to 100% state of charge is an expensive and noisy business. The group 24s are overmatched by boondocking for more than a day or so. For longer life, don't take them below 50% state of charge. Consider SiO2 chemistry when the group 24's fail. SiO2 do not require being fully recharged and can be used down to 20% state of charge.

RE: Canadian Snowbird Future

wapiticountry, So you think the 21 million Canadians who don't go south, will spend less in Canada than the 12.5 million Americans who won't be going north? I'd say your math flawed. I'm not in favor of Canadian borders to any country being opened any time soon. USA only had 58,349 new cases today--and usually on Sunday there are a lower number of tests done. The Province I live in has only 47 active cases. How many in the State you live in?

RE: moving up to 50 amp from 30

Im thinking about running a permanent power supply to the camper from the garage about 50 ft away. I am having a carport put in so I can keep my new baby covered,and I can put underground wires from the breaker box in the garage to inside my carport.30 amp should be enough to do what I want to do. If you are doing DIY there is little cost difference to going to 50 amp.

RE: Canadian Snowbird Future

For the latest data available 21 million Canadians visited USA 12.5 million American's visited Canada “This is clearly the currency at play,” he wrote in a BMO trends report, adding, “Note that even now, there are still two Canadians travelling to the U.S. for every one American visiting Canada. In the 1970s and early 1980s, the ratio was 1:1.” So USA will be on the wrong side of the scale, economically.

RE: Canadian Snowbird Future

If the US is such a threat to Canada, maybe the border should be closed permanently. I wonder which country has a greater percentage of their population cross the border in any given year. My bet is Canada would suffer more than the US. And how often have you come to Canada? And that would be in January? USA is causing its own suffering. Just why that is happening I'll leave to your fertile imagination. There is no doubt in my mind, that far more Canadians snowbird to USA, than US citizens visit Canada. So USA may hurt financially from the lack of those folks not buying goods, food, and accommodation. I do know that in a two week period in June, over 72000 Americans excluding Truckers, crossed the border going North. There must have been a lot of folks returning to Alaska......or perhaps the visitors were telling porkies to the border officials? BTW I'm not anti American. But I'm definitely anti Covid 19. Or perhaps Covid 19 and the 137,572 folks who have died in USA, are all part of a hoax?

RE: NC campgrounds with good internet

What you are hoping to find is as rare as hen's teeth. Far better to use your cell phone with an unlimited data plan. Unlimited does throttle once a certain amount of data is used. They call it "net work optimization". My only internet source is my cell phone.

RE: moving up to 50 amp from 30

Continue to use the system that served your 30 amp RV. If there is an Energy Management System, I'd set it to 15 amps to limit breaker tripping at the shore power breaker box. Do use a #12 or #10 extension cord, if greater length is needed.

RE: Are RV sewer hose supports necessary?

Hi Bobbo, Some times the sewer connection is 4 or 5 inches above the ground. In that case a support might be useful, but not essential.

RE: Canadian Snowbird Future

It’s becoming obvious why Canadians would rather keep the border closed! Over 430,000 new cases in a week says it all. That's more folks than live in Regina and Saskatoon.
pianotuna 07/11/20 10:25pm Snowbirds

monkey44, This site says total cases: https://www.worldometers.info/coronavirus/#countries It also lists total tests, etc.

RE: Decent inexpensive modified sine wave inverter

I ordered Krieger 2000 Watts on this web and it is real. It works great! We have been able to convert DC power from our batteries to AC in order to use appliances such as hairdryers and microwaves. The remote control is an added bonus! No need to access the inverter to turn it on or off. If you are looking for an inverter to convert from battery power for household use, you will love this inverter! Hi, There is no real testing at that site--it appears to just be one persons opinion.
