Is more solar power always best - Portable solar panels compared

Having owned several 200w & 100W portable panels I was itching to go bigger and try 400w panels but the practicality surprised me between the different panels especially the weight and price of the bigger panels so it's an interesting thing to consider what's best for you, more smaller panels or fewer larger ones .
This video has some interesting tests showing the panels side by side.
Rigid house style panels are absolutely not portable and a non starter but even 100w rigid panels are surprisingly difficult to transport in the average car if you're taking other things with you. Folding portable panels are much easier to carry and easier to transport .

Great to see all of the options you have out together. I would love to see how much energy they actually achieve and wether the larger ones are more efficient.

Maybe I'll put them all out again 🤭

There's no excuse for the 400w panel being so expensive. I've just purchased new 450W trina panels for circa £80 each

@EVPuzzle 24 дня назад

@@SabretoothBarnacle snap I paid 60 each for Trina 410w.. rigid panels seem to be made of more expensive materials too. Maybe the fabrics are expensive to sew and stay waterproof or maybe their volume of sales isn't higher enough to get prices down

@mossup- 24 дня назад

wow, I never realized how big the 400 watt panels were, it has made me think about changing my plans to using smaller panels instead, I just assumed that they would be way smaller.

Hopefully you are still happy with the MINI? It would be great if you could do a 'buyers guide' so those of us interested in getting a used one know what to look out for 👍

@stevenbarrett7648 24 дня назад

We have a Bluetti 2-panel fold-out, I believe its supposed to be about 120 Watts, at best we only ever get 40ish Watts, quite disappointing. Generally I don't feel any panel gives its full output, it must be calculated the same as they do for car ranges, fingers crossed behind their backs !. Our best input comes from the boot of the Tesla, plug the Bluetti in to the 12V outlet go for a run around and come back with a full charge ready for another days use in the caravan

@EVPuzzle 24 дня назад

When I charged my mini from a few of these I saw full power on a sunny day . Doesn't take much to lose some power but I've been happy with all of these . If conditions aren't perfect I expect a lot less of course but always good to have seen the max output at some point

@theferreira8632 24 дня назад

Plz do a compare on cheap solid solar panels... that would be interesting

@EVPuzzle 24 дня назад

@@theferreira8632 what type of criteria are you looking to compare ?

@theferreira8632 24 дня назад

@EVPuzzle power to value ratio. Example: if space is not a issue, is it better value to have 4 x 100w solar panel costing £400 or a single 400w panel costing £600. Just a example. There will be people looking for panels with limited space theres loads of people who can sacrifice the space for the same power but cheaper budget.

@EVPuzzle 24 дня назад

@@theferreira8632 I'll save you watching a video , 400w is 400w The only significant difference in fixed panels is the bigger ones with more cells split into two sections can really help with shading losses and bifacial can help a lot when ground mounted but still 400w is 400w. Forget efficiency numbers too. 400w is 400w Imo choosing panels is about size to fit your space to maximise output plus how it looks, all black or silver etc plus quality of materials. Will it last .

@FancyaBevMate 24 дня назад

Nice information matey, can i ask a question regarding your home storage ive seen its around 14kW how many rooms are you heating for your daily usage? we have a 2 bedroom bungalow so 6 rooms total. We're looking at changing over to a heat pump and storage to go along with our 4kW pv any suggestions on brands and storage size would be helpful nigel. Cheers

@EVPuzzle 23 дня назад

Depends on your heating if course , heat pump etc Our a2a heating is covering lounge , hall, bedroom . 3 x bathrooms use immersion in radiators as towel rails . One bed uses infrared mirror as only occasional use, 1 x bed , kitchen and dining room not heated , door open , hall heat is adequate

Does that large 400w panel have a micro inverter glued on the back of it?

@EVPuzzle 24 дня назад

@Pegaroo_ 22 дня назад

Have you checked the output of the panels? Are they the wattage they say they are?

@EVPuzzle 22 дня назад

See my video on charging my mini with them , they worked perfect

@Richardincancale 24 дня назад

I was hoping having put them all side by side in the sun you would check the output of each one? Which gives most output per £ or per kg?

@EVPuzzle 24 дня назад

Can't test everything ... I've tried most of them together in my video charging my mini from solar . They all hit the Max output indicated in perfect conditions

@kavanobrien6547 24 дня назад

The 200watt panel how long does it take to charge a portable battery pack ? And how long would I get in the battery pack if I used a small fan heater, thinking about winter already. One more thing how much is a small portable battery pack ? Sorry another question would I be better off getting a small ATA heat pump rather than the solar panel and portable battery pack.

@EVPuzzle 24 дня назад

How long to charge depends on how much sun , angle and battery size if course . 200w max so even if perfect 6 hours to fill 1kwh battery from empty ....10% loss A2A is a much simpler proper solution but portable battery and a small infrared panel would give you a portable effective heater. A2A isnt portable so it's all about how much portability do you need for that heater . If it's a serious heating solution you're after a2a. Portable stuff is a nice extra imo

@kavanobrien6547 24 дня назад

@@EVPuzzle I saw the price of the panels on your video, could you give me a price on a portable battery and a good one that would last rather than one that won’t last I suppose a reliable one is the word I’m looking for , only got the old age pension coming in so I need to be clever with the money, boiler broke two years back so the last two winters have had one fan heater which is costing a lot with electricity, so really after something that would give a bit more heat but more economical to run as far as the bills are concerned.

@EVPuzzle 24 дня назад

@@kavanobrien6547 considering a decent fixed panel could cost £50 these days , portable panels are a luxury item. For best economy bargain rigid panels are the way to go but of course they're big and heavy Personally if cheaper warmth and comfort are the aim I'd say a smaller A2a system might be better or even infrared panels to provide directed hear directly to you, you'll feel warm even if the room isn't everywhere . A single panel head or there isn't going to save much money but a couple connected a battery could provide free heat if the sun shines or at least a few hours of cheap heat . Sadly the most reliable long lasting batteries are the most expensive Used batteries are of course better value

@kavanobrien6547 24 дня назад

@@EVPuzzle could you recommend a good portable battery I mean the product name and the power or I mean the identification = sorry not very knowledgeable hope you know what I mean , so I could check the price on EBay , I saw a gentleman install a Electriq mini split with one blower unit = he seemed quite pleased with the results, what’s your thoughts on Electriq products or you may have no experience with that company, so I would like to check out both scenarios, is it a stupid thing to say I was thinking about putting the small solar panel in the window inside = yes I know the the angle might not be correct but have the front of the house having three south facing windows along with front and back doors also south facing in my head it’s saying I could take advantage of that somehow, even making indoor blinds out of flexible solar panels link the wires from each panel somehow to generate more power , another crazy thought is to get a flexible panel for each window linked to a tiny portable battery for each room with a tiny heater = makes sense in my head but so does flat earth to some people , maybe the thought of another winter without heat is making me more crazy = just stop thinking maybe your answer.
