what is the weight of solar panels . i want to use the flexible and fordable solar panels on RC Air craft. please help me to buy.

This particular panel is heavy weighs like a small rug. If You're trying to create a solar powered rc plane, this ain't the panel. This panel is as long as a minivan, it works great, but not rc airborne.

Sorry when I purchased it, they were sold together on amazon. I do sell items for northern tools, I found a 30 watts solar panel there. They sell it for 149.99 plus almost 9 dollars for shipping. If you think it will work for you, I can order it for you a little less. I could place the order for you at 148 which would include the shipping fee. If you are interested I could send you a paypal invoice if you send me your paypal email. Here is the link to check out the solar panel: http://www.northerntool.com/shop/tools/product_200610284_200610284

I wouldn't recommend adding any additional weight to this little bird. I even tend to fly mine with the canopy removed, seems a bit more responsive that way. Even with a higher mah lipo, the added weight of the bigger cell can hardly even extend flight times, much less provide any additional lift. Also, adding additional weight will dramatically reduce the life-span of the small brushed motors. Still, for the price, its a very fun quad to fly.

This is a very nice solar panel that is mounted on a somewhat flexible metal sheet. I produces about 16v dc at the contacts in Florida sun (rated at 12v for a 12v battery), but I use a solar controller so it won't overcharge my battery. I have it hooked to a 12v trolling motor deep cycle battery on a small boat. I have not had to externally charge the battery since attaching the solar panel, and that gives me a few hours per week of power.

Yes you can get a close approximate figure but solar conditions vary constantly. I turned on everything in my shop so the inverter called for a lot of amps from the batteries and thus the solar controller increases the amperage output to the batteries. Take the amperage figures from the LCD display and multiply it by the voltage of the batteries and that will give you the amount of watts being used at that time. In other words if your LCD meter says the batteries are getting 35 amps charge and you have 13.6 volts to the batteries then 35amps x 13.6volts = 476 watts being utilized from the Solar Panels. This is only approximate because there are various losses but the figure will be pretty close. Yes you can get a close approximate figure but solar conditions vary constantly.

Do lots more research before making any purchase. You saying 750KWH/month says to me (750 / 30) 25KWh/day. If that were solar panels, that would be about 12,500 Watts of solar panels in a 2 sun/hour day area. Somehow I expect you mean something else, tho some homes use that.

All you need a Solar panel and lots of sun. I recommend you purchase the Goalzero Boulder 30 solar panel. It is expensive but I found that it does as advertised. I have several of the Yeti 400's as well and several of the Boulder 30's. I am to date, pleased with them both.

They are about an inch high. I installed them on solar panels at my property in Hawaii and I am not there now to actually measure them. They are currently holding about a 27 lb solar panel. You use 4 per panel.

The solar panel is plenty strong. There are no weakness issues in the design I can see. It's really been useful camping since it also will charge cell phones!

It is pretty hardy for a solar panel. I take it backpacking and store it on the outside of my bag. Last hike I forgot I had it on the outside pocket of my pack and tossed it waist-belt up in my trunk. It was 50lbs. I thought for sure I broke something. It was fine. I seriously am blown away by this thing. Get it. Treat it best you can of course. I will never forget where it is attached again! it is a solar panel after all, they are inherently a bit fragile.

These solar panels are the best. They are a little heavy though. My experience with these panels to have a very good experience is to plug them into a 30 Amp Solar Controller into the input side. On the Output Side of the Battery Charger going outside the controller plug in this device first, Lanzar VCAP5000 Vector 50 Farad, 16 Volt Hybrid Capacitor on the input side of the capacitor. On the output of the capacitor, is the side to charge the battery cells. The logic for this is that the capacitor hybrid cell is storage for the solar cells because the prediction of cloud positions are random and hard to predict on any given day. Thanks, Dr. Sheldon Cooper.

In my opinion, nothing about a less than 200 watt solar panel build requires a professional. In fact, it can be quite a fun DIY project. Knowledge is really the only obstacle. Getting the best angle and position of the panel can be a bit of a challenge and you also need to watch the length and gauge of cable that you use to pass from the panel to the controller and from the controller to the batteries (lower gauges and longer cables result in voltage drop).

They have a pane of glass in front of the solar cells which could break, especially if hit by something. I think all panels of this type do. You might be able to take the frame apart and replace it with plexiglass. If you want the toughest, the roll-up flexible panels from Unisolar are less efficient and more expensive but appear to be nearly indestructible.

a morningstar 60 &lt;AMP&gt; controller will not be big enough, this is what I have for just 3 of the panels, and it is maxed out. Have you looked to see if you can put 5 on top ? I have a 35 foot RV but there are a lot of things up top that get in the way... Anyway, get the 80 amp morningstar and maybe just 4 panels. The grapesolar and the morningstar have worked very well for me. I would also suggest the remote panel(s) good luck !

You can use any type of solar panel. If you are using solar panel which has wattage of 180 to 300 watts, you can use minimum 5 panels and maximum up to 1750Watts. We can also provide you solar panels at competitive rate.

I'd be skeptical that any solar fan has the oomph to move anything but the lightest flaps. I mounted mine in a box for attic of camp, I can pull out insect screen at end of season and drop in a blank (sheet of wood) for winterizing.
