Inselanlage Solar 12v auf 230v
Habe im Sommer eine Inselanlage im Garten installiert. Funktioniert seit ca. 3 Monaten tadellos. Ob die Leistung des Solarmoduls komplett 100w betrgt kann ich nichts sagen, da ich kein Messgert habe. Jedoch habe ich 2 Autobatterien mit insgesamt 96Ah (12v) angeschlossen die bisher immer voll geladen waren. Zur Stromentnahme habe ich einen Inverter mit 300w und daran eine Steckdosenleiste angesteckt.

Bisher alles top!

Very happy with panels
Bought 4 panels, mounted them on the roof of my camper. I used Z brackets, to mount them parallel with the roof. Wired them 2S2P and I use them with 4-100AH LifePo4 batteries, through a 100V-60A controller. Haven’t had to use my generator at all, since installing them.

Updated Review - Great panels for starter solar power system.
Adding to this review as I had since purchased another of these panels and had also replaced the Mohoo 20 amp with an HQST 30 amp MPPT controller. (The Mohoo is a great little piece of gear and IMO economically the best choice for single panel, smaller systems. I am saving it as a spare and for another project.) The HQST 30 amp MPPT is a truly advanced piece of equipment that is well suited for all aspects of battery care under changing conditions. My learning curve has been steep but in summary the two panels hooked in series are worth more than the sum of their parts as a 24 volt (upwards of 40-42 volts on the output side) feed into an MPPT controller and from there to a 75 amp hour 12 volt Great Start Marine deep cycle. It has been nearly the equivalent of adding a third panel. Since I will add two more of these panels at some point in the future, these efficiency gains will grow with them. In the Mono- VS Poly debate. I don’t have any mono’s just yet but the these polycrystalline panels perform surprisingly well even when the light level is low. On bright cloudy days, combined with the MPPT controller, the two of them can produce around 2 amps at 35-40 volts and that translates into a good charge for the battery even on a cloudy day. (Scattered light from clouds also increases their output while they are shaded which helps.) They produce even in the rain albeit at around half an amp or so. The differences between the two panel types are really not that significant in my opinion, not nearly as much as in the choice of going MPPT and/or running a higher voltage. The cells are 18% efficient in optimal conditions and on cooler sunny days with the wind blowing, they really amp it up. I’m looking forward to seeing how they do in winter. The shorter days should be offset by cooler temps and leafless tree shade. Alas, high heat does seem to take the output down measurably (roughly 10% or so) but even in those conditions, the power yield is still ample. Mono is said to be more tolerant of high heat in maintaining yield. —- The big weakness and my limiting factor, is the battery. I need bigger a one and more of them. These two panels and the controller are getting the battery to float voltage as early as 2-3 p.m. Flooded lead acid deep cycles (Trojans or something with thick plates) would probably be best as the water levels (and specific gravity) can be checked and maintained and they are less expensive for the amp hour. I’ve read that over/under/mis-charging and dehydrating an AGM or other fancy sealed battery is pretty much irrecoverable for it. AGM is really efficient and capable of a high number of cycles but FLA seems more forgiving for the amateur. I’ve moved the battery outside for safety reasons and it seems to work well there.

Will update again at a later date. 08/26/2016

Very happy with this solar panel. I settled on this one because of the design, other good reviews, price and also because the processes of manufacture for modern polycrystalline solar cells use less raw material and energy than other types of cell manufacture and am making more decisions in lifestyle which include environmental impact. It also seemed like a good match with the Mohoo 20 amp controller which I ordered and am so far happy with. It came on the day specified and was pristine, even beautiful upon opening. No damage or unpleasant surprises. Installed it on a couple deck boards cut to match the top of a southwest facing window awning and its dimensions and weight are a good fit for it. It even looks nice, like an accessory to the awning. I tend to favor function over appearance but it was not difficult to make a decent looking installation of this. The “Z” mounting brackets are a must. They make attachment to the supporting structure so much easier and more secure. The aluminum seems very high quality and is light to handle. I was able to hold the panel with one hand while getting it in place on the awning. The high grade end cable connectors were a good decision too. I soldered the metal pins onto the cables and had to work with them to get them fully inserted for a good connection but once connection was established they have carried full current. So far very happy with the panel’s performance and plan on buying at least two more of these to mount on an adjacent and larger awning. At dawn it produces between 0.3 and 0.6 amps as it is in tree shade for the first hours of the day. Amperage builds as the sun rises and have seen it drive 5.5 amps out of the controller in sunny mostly clear conditions. Max closed circuit amperage is 5.62 so either true performance is better than that and/or power loss in the cables and controller is less than expected. When clear and out of the shade it produces 5 amps plus until about 6 pm (july) so I can get about 6 hours of full power out of it. It has bypass diodes that help balance production when some of the panel is shaded. It sustains between 1 and 2 amps in partial shadow or bright clouds. (An MPPT controller would probably glean 10-15% more out of it in those conditions.) Have it charging a large marine deep cycle battery and have about 20 feet of 10 gauge low voltage lighting cable between the controller and the panel and 12 gauge solid wire to the battery and from the load circuit to the 12 volt system outlets. As part of a starter system it is affordable and simple enough to give the residential solar engineer worthwhile experience by which to competently plan, select components for, and implement more advanced and larger systems. I have a separate set of 12 volt and generator wires and conduit run through parts of the house for emergency lighting, fans etc. that is now fed from the load circuit and is running some 30-50 watt equivalent luminosity LED lights, the DSL Modem, and cell phone chargers. Will put in a pure sine wave inverter later and want to replace the marine battery with a 100 amp hour AGM deep cycle. Plan on hooking up my 12 volt Coleman cooler and a couple 12 volt fans in my basement office when I get more panels hooked up. It could be taken down and with a portable mounting used remotely in the field, on an RV or boat if desired. Pamphlet states that it is robust and resistant to impact damage and low pressure water jets but I am wanting to fashion some kind of easily fastened (hail) storm cover for it. In summary it works well and fully meets its stated performance criteria and has every appearance of being a long lasting device of high quality. It It fits in places not practical for the 250 watt grid-tie panels yet produces worthwhile wattage.
