Hi Ronny, Dave from Rolasolar here. Great video some added information for your viewers. Temperature Coefficient: Solar panel temperature is one of the important factors that affects how much power a solar panel will produce. So the more sunshine generally the hotter the solar panels get and this in turn reduces the solar panel output. In some cases the heat can reduce output by 10% to 25% depending on your specific location. Looking at the manufacturer's data sheet a term called "temperature coefficient at Pmax" should be listed. For example a monocrystalline solar panel with a temperature coefficient at Pmax of 0.50% means is that for each degree over 25˚C the maximum power of the panel is reduced by 0.50%. So on a hot day at a solar panel temperature of 45˚C the power would be reduced by 10%. Conversely in cool conditions output would be higher and in temperatures below 25˚C the output can be high then rated. Not all solar panels are affected by heat equally and some do much better at coping with the heat than others. Amorphous solar cells are known for their low light performance and shade tolerance. They also are also better in high heat conditions than monocrystalline and polycrystalline cells due to their lower temperature coefficient value. Amorphous solar cells will always yield more power into your batteries throughout the day then mono of poly of the same size. If retailer can't provide the temperature coefficient values for the solar panel - walk away. Best way to prevent heat loss with mounting semi flexible solar panels directly to metal surfaces is to mount them on a backing material like core flute which allows air flow under the solar panel.

Hi, Dave from Rolasolar here again. Some added info for mobile and portable solar panel buyers: Did you know that most mobile/portable solar isn't certified like building solar. This leaves the buyer open to being scammed with uderrated and poor quality solar? How do you know that a solar panel is underrated for its size, because there is a standard size for a solar panel for the power output. 12V monocrystalline solar panels with a cell efficiency of around 17- 20% should be roughly 0.0064m2 per watt. If there is a substantial variance from that, you are being misled. Listed below are rough sizing you should be looking for in a monocrystalline solar panel: 80W panel = 0.512m2 100W panel = 0.640m2 120W panel = 0.768m2 150W panel = 0.960m2 160W panel = 1.024m2 200W panel = 1.280m2 250W panel = 1.600m2 300W panel = 1.920m2 If you want to know that the panel you are looking at is actually the wattage advertised, do the math above, or jump on a reputable sellers websites like Everdrive or Redarc and compare sizes. As an Example one of the 200W fixed solar panels from online is 1170mm x 510mm or 0.597m2 which equates to approx a 95W solar panel. This scam has been going around for years but seems to be ripe on the auction and other cheap product websites. Do your own research don't be misled by the scammers.

So best thing to do is set up your solar panel when it's raining! 😁

As an electronic technician for the last 15 years, this is the best simple practical explanation of small scale solar I've seen. Great work! This is the video I'll refer people to.

Tip: If you got the space on you car (approx 1700x1000mm)and a charger/mmpt that can handle the higher output voltage (approx 35v), talk to you local solar sparky. They often got old house mounted solar panels they are happy to get rid of. You often get em for free or for a carton/six pack. Got a 220W panel for free and intend to run it with a Victron cyrix-ct vsr and a smartsolar 75/15 (or bigger). Get a deep cycle battery and you got a set up with enough power for 500ish $, unless you can source a deep cycle battery for cheap (ask a fire sprinkler guys etc). Don't go camping very often so I try not to "waste" a lot of money in big brands.

Thank you very much ,great info,I'm old so I will have to watch more than once,keep up the good work.

Great job simplifying something I find to be over complicated. Keep these vids coming!

Thank you, Ronny. This video was exactly the level of info I needed. I appreciate the purchasing advice.

This is such a good video bro... exactly what I need learning to get get onto 4wd life. You break everything down in perfect detail and no bs. What a legend

Thanks Ronny. One man can only research so many things or comprehend so many, that is why someone like yourself is such a great resource, not to leave out great videos!

thanks so much mate, i love your videos and passion that goes into them. im getting ready to set up a new dual cab and hit the cape and fraser. you have taken all the guess work out of my planning. thanks again, be safe... dave

Perfect no nonsense, no rambling straight to the point video 👍🏽 Cheers

thanks for keeping it simple for us new to trying to get our head around solar setup

Just re watched this Ronny and what great collection of info it is Will be relevant for a long while yet

Excellent video man! I havent seen another that explains so in detail all the aspects of portable solar stuff. Thank you very much!

I do a lot with remote solar systems, I found your video to be excellent, spot on and easy to understand, very good, thanks for doing.

THANKS RONNY! Great video, one of the best technical videos so far!

Thanks for another great informative video. You've helped us out considerably on our two builds. Keep them coming!

A good video mate. It answered a couple of questions I had in my mind and there were plenty of other points I made note of for future reference.

Thanks Ronny...this helped me a lot...many thanks for taking the time

Thanks for the video, most informative one that I've watched yet. Cheers!

Really helpful info I’m in the market for solar power and this vid has helped heaps!

Great video! While watching, i was actually wanting co comment on the thing where if you're on a budget, you'd be better off spending more on the controller and skimping on the panels, but then you made that point at the end, so good on you! But it's also nice that your videos cater for budget/DIY guys, in that you agree that sometimes you can buy the medium quality stuff, and basically get the best you can afford. Lots of other guys on KZread are all "Get this because it's the best, Don't worry about that second mortgage.." Thanks from South Africa, Keep up the great videos!!!

Awesome practical video with no marketing BS

Love your work Ronny, keep them coming mate! I have 120w blanket that seem to keep up with the 80L dual zone fridge when parked up for the day, with a 130 Ah AGM dual battery wired in, and I use AC charger every so often.

Very professional and concise video. Absolute Champion! I came away more knowledgeable about the basics of solar panel and controller quality and differences effecting efficiency - all in a short ‘to-the-point’ video. You know your stuff and value the viewers time. Thankyou 🙏🏻 Keep up the great work. 👌

I like the grading system. Very fair. Well done. Thanks

As usual, objective and well explained, thanks mate :)

Thanks for all the good and simple advices.

Like all your videos, fantastic. Was just the basic overview I was looking for as I being to research this part of my overlanding build. Thanks!

Excellent video Ronny. a great help especially concerning the controller.

Awesome - just in time as I start planning for an expedition!

Thanks Ronny. We really got maximum information. God bless you.

Keep em coming, Ronny, very helpful!

I have a Kings folding panels which I had mounted flat on my roof rack, used only when parked up for a few days. It worked ok. I have since mounted a hard shell roof top tent, so I have now got a kings solar blanket which will be used when parked up on my next trip in a couple of weeks.

After all the effert you spent, someone selects dislike!!!why? Thank you very much for this effert,your explanation is the best I have ever watched👍👍👍

Best video on here for the information I needed. Thanks

Nice topic Ronny - well done!

Great vid Ronnie. Definitely helped with my upcoming choice of setup.

Brilliant video; super helpful, thorough and easy to understand. Great content.. Would also like to hear about your truck, specs, model etc.

that was great Ronny, helps me to make my mind up about which one I should buy

Awesome video, help me out so much with understanding solar and what works best for me

great video mate. love the knowledge. helped me decide on my blanket decision

Informative and well presented. Cheers for sharing your knowledge and experiences 👍🏽👍🏻🇦🇺

Thanks for the video Ronny I always wanted to learn more about solar.

Really helpful video and great advice for my solar power purchase.

Hi from The USA. Great info. Love your videos

Another great video mate. Cheers

More please. Thanks for all you do.

Thanks Ronny! Nice! Thanks! Great info! this is kind of you to explain this thank you

Thanks Ronny very helpful video

Thanks for tha Advice! I am ordering a MPPT controller to replace my PWM unit right now.

Holy cow those blankets are expensive!. Best solar video for camping I've seen yet!

About time someone can talk the walk,big thumb's up,

Hey Ronny I love your videos,great videos,Hi from Miami Fl USA.excellent work👍👍👍👍

That was very informative. Thanks

Thanks mate I’m looking into solar panels so your video helped a lot 👍👍👍

Great stuff Ronny.

Awesome video, this answered a lot of my questions. Thanks mate

Great video Ronny. Also good information.

good run down on solar thanks Ronnie, we have a cheep folding panel which came with an "MPPT" controller, I chucked the controller and as you said have a DCDC controller near the batteries in our camper. this also provides a proper charge from the car when towing. its only a 120w panel but it runs the 70L fridge and our lights just fine.

I have a fixed panel on the roof but have a blanket I can run out when camped up as well. Just wired the plugs in parallel and feed into my 1225D BCDC. Works really well.

Very well presented and explained. Cheers.

Excellent video and some great information. Scott

you forgot to mention that glass is the only transparent material that can last in the sun full time. all the flexible panels will only have a service life of 6 months permanently in the sun before they go opaque or delaminate and then output only 1/10th of their rating

2JZZ12 Cheap material usually PET can have the clouding affect and can deteriate after constant UV exposure. ETFE material used on quality semi and flexible solar panels has been UV tested for thousands of hours. Its the same material used on flexible grid tied solar panels approved for a 20+ year service life. With all solar panels as with all products you get what you pay for.

Awesome video, thank you!

An excellent explanation - thankyou. Now I know which type of solar blanket, controller to get.

Luv this help, much appreciated.🤗

Great video. Thanks.

Pretty good overview. I like how you pointed out the efficiency gains of the amorphous (most people simply say they are "less efficient" because they require more surface area per watt. Is a tractor less efficient that a micro car when plowing a field? Of course not). You didn't mention that the amorphous panel is also more efficient in hotter conditions, though all panels do lose efficiency as they heat up, as you mentioned. An amorphous panel will still continue to put out amps as the sun sets, well after the mono has shut down. If amorphous were only slightly more expensive, I couldn't understand choosing anything else, unless you were really tight on room. As it is, there is a huge price difference. Overall, very good overview.

Thank you, very informative

I have a 250 watt foldable solar panel connected to a Projecta DC to DC charger in my camper that has 2x 100 amp hour batteries. We run coffee machines, fridges lights and other auxiliary power, and have never run out of power. I think your video this morning was very informative for anyone starting out. Weld one and keep up the good work.

Good vid mate I have used a kings solid hinged panel run straight to my battery once parked up, been awesome so far over the last 4 years been N,E,S and W plenty of power (160W I believe) for general travel inc one fridge lights for night Etc 👍

THANK YOU FOR DETAIL VIDEO

Very good video mate! Thank you..

Great informative video mate.

Excellent vid!

Thanks mate for the tips 👍🏼

I have been thinking about a solar setup for when I get back on the road for many years. I bit the bullet and started on the setup. I've gone with 2 x 138A/h AGMs, 2 x 160W fixed panels, a 12 Volt controller and DC-DC charger/regulator, and a 3000W pure sine wave inverter (I'll be using a computer and other electronics). I've got a 3000W petrol genset as a backup. It may be overkill but I will be using a fair bit of power. The ute will basically be a mobile bush mechanic's workshop (and video/photography studio) with a fridge, shower, stove, and bed.

3 x 120w foldable panels from ebay (other $120 each), ripped the PWMs off, replaced the diodes for schottky's as the panels themselves were German qulity. Then mounted the epever tracer Mppt 30cm from the 300ah Giant battery + dual battery 150amp fused blah blah.. 7 months touring east coast of Aus with 2 x 40 litre fridge / freezer.. worked a treat.

Thank you. Very nice, helpful video. Cheers

Thank u that was magic. I have mono blanket 200 watts

Excellent informative video, thankyou.

yes, you are so right

Nice one Ronny

thanks allot ~Ronny, epic help

Thanks for the video

Great video Ronnie, keep it up! I recently bought an Intervolt DCDC (which is a Perth company) for my Prado and caravan aux, how about a review video? Very happy with it, and love supporting local
