Coleman 30W 12V Crystalline Solar Panel

Déjà propriétaire de 2 panneau de 15W 2-3 fois plus long que celui-là de 30W. Aussi j'ai un autre modèle de 40W. J'ai ajouter 2 panneau de 30W il y a quelques temps a mon installation. Je dirais que tous mes différents panneau en plein soleil vont donner 20-23V de lecture sur un voltmetre....mais cela est sans charge (load# de branché. Si vous brancher quelque chose qui tire du jus, vous verrez la tension diminuer...ce qui est tout a fait normal. Des que vous depasser 10-15W d'installation de panneau ou que vous laisser en permanence une batterie pour la rechargée, vous devriez utiliser un contrôleur de charge, ce dernier a pour fonction principale d'ajuster la tension a 13.5-14V pour permettre une bonne chrage de batterie sans l'endommager. Pour revenir a ces panneaux de 30W, ils sont trop recent sur mon système pour parler de leur efficacité par rapport a mes anciens, mais leur dimension #14x19# a fait en sorte que j'ai été capable d'en mettre 2 de plus car mon espace de toit était restreinte. #mes 15W font 14"x36"#

J'ai acheté ce panneau au début de l'été, et tout fonctionnait bien avec un petit régulateur de charge coleman. Après quelques mois, il ne donnait plus 13v comme supposé, mais 20. Je l'ai échangé, et l'autre aussi donne du 20v, ce qui est trop pour des batteries conventionnelles 12v. Avec ou sans régulateur, le voltage est à 20v. Je ne sais pas quoi faire avec ça. J'en ai un 40w aussi et lui fonctionne relativement bien, donnant 13.8v à 1.3a dirigé sous le soleil de midi, ce qui est loin du 40w supposé dans les conditions idéales (donne 18w).

I have purchased two of these, and tested them thoroughly under different weather conditions. They are very sturdily built, quite compact, and function properly. Note that these are panels only. The box does not include a charge controller, and the attached wire is fairly short, although it does include a quick connect/disconnect. You will need to wire them into your own system (such as an RV or boat) yourself. Do a bit of research and planning regarding what else you will need, e.g several feet of 14 gauge wire, some wire connectors (such as butt connectors or marettes) and a charge controller (an inexpensive controller will work fine with these panels). The panels I got in my box are of the monocrystalline type, although the box only states "crystalline", so it's possible that future boxes could contain polycrystalline panels. I tested the panels in wet, rainy conditions for a couple of days, and they are weatherproof. Understand that the wattage rating given for virtually every solar panel is a BEST CASE value that most people will rarely, if ever attain. I've found that my panels put out around 15 watts each under sunny conditions, but I live in Whitehorse, and with the higher latitude, the sun is lower in the sky. Try to orient your panels so that they directly face the sun, in order to get the most power, and you may get between 50% and 80% of their rated power. In shade, expect maybe 25%, in overcast and rain, maybe 5-%10%. I do recommend these panels. However, know that they are panels only, and also that you will not likely achieve the rated power, so if you need 30 watts, then buy two of these, or a more powerful panel. This is not a knock on this particular panel; that's just the way solar panels are... their power ratings are maximum power under ideal conditions which are rarely achieved. All in all, this is a very good product, and I recommend it at this time (although I have not had the panels for long, so I cannot comment on long-term durability). Be aware, though, that solar panels in general are continuing to get less expensive, so try to buy panels when the are on sale.

So the cable that is included with this panel is about 6 inches long and has a quick connect cable on the end of it. The "required" charge controller does not have a quick connect and in fact in the manual it tells you to strip the wires and connect them that way. I have still yet to find adapters so I don't have to cut the wires to the panel I just spent $100 on, so I'm not terribly impressed with this purchase. I have not tried it yet, but I hope it performs well to make the purchase at least worth it, because I can't really return it after I've cut the thing.

I use this product and other products similar to charge boat batteries, and run solar systems in my house. I think the green energy or solar department at Canadian Tire is excellent and the products perform as indicated. They are plug and play, easy to use, and can be combined to increase the overall wattage output to charge battery banks, etc. Some solar products come with a variety of connectors which are useful to create a combined solar array, to supply energy for a solar powered system. I am completely satisfied with the solar products sold at Canadian tire and will continue to purchase solar panels and related equipment there as I increase my three solar systems in our home to run more appliances and lights, as well as power electronics on the boat.
