One of the kits which was displayed in our local Costcos long ago did have the PVC tubing frame. The kit I saw there most recently (last month?) was only in the box (no display model) and I don't think it had that frame.

The cables and connectors - including the battery clip and other ends - described by John sound essentially the same as those provided with my single 30W panel from Canadian Tire, sold under their house brand name... there are not many truly different sources of these things.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.

Harbor Freight now has the $249.00 regular price marked down to $199.00, good until March 26 in the store I go to. I cannot find a 20% coupon in the link referenced. Am I doing something wrong, or has it expired?
Thank god!! I thought I was going blind!!

Life is good!

I just bought the Harbor Freight 3 panel 45 watt special for $199.00 i now need to buy the inverter.

Can anyone recommend a good brand and is 300-400 watt enough for these panels?

I need to purchase fairly soon as i am leaving on a trip!! thanks for your help!!! Dee

Are you looking for an inverter (converts 12v DC to 120v AC) or a charge controller to regulate the solar panel's output to the battery?

For the latter I'm a fan of Xantrex products as they have a good rep in the marine industry. Although I should admit that I have no first hand experience with solar panels I've researched them a number of times. (But I did stay at a Holiday Inn Express! )

If you're really talking about an inverter, I think you may be disappointed if you plan to hook the inverter directly to the solar panels. Regardless, a 300 watt inverter will deplete a battery more than twice as fast as the panels recharge them. It's my sense that solar panels can often keep up with 12v loads (in sunny locations).

Harbor Freight also sells a 400 watt invrter. As you know their panels come with a frame to orient toward the sun. My panels are mounted on my back porch roof. I use them to run a string of 50 led patio lights during the summer months. I also charge all rechargeable tools, phones and appliances as well as batteries. This is my backup emergency power system.

New solar panels? Welcome to the world of solar energy!

The cheap (about $30-$35) 7 Amp solar charge controllers sold by Harbor Freight, Northern Tool and many sporting good stores are an OK -- but not great -- charge controller. If you want a better performer for a few bucks more, take a look at the Sunsei 10 Amp controller ($35-$45) I have. The Sunsei controller has two charge rates, one for when your battery has been depleted and a second "float charge" rate that tops the battery off and keeps it optimally charged. It also has a status light that tells you when the solar panels are connected correctly and whether the panels are busy charging the battery or not.

The ampere rating for the controller is not an issue here, by the way. You'd have to connect two 45-watt Harbor Freight solar setups to the 7-amp controller before you'd hit the controllers maximum capacity.

As for inverters that will convert 12V DC battery power to 110V AC household power, I have two inverters. One is a no-name 100 watt unit I picked up at a local auto parts store for $25 and plugs into a cigarette lighter (for charging my laptop, iPod, cordless drill, etc), the other is a $40, 400 watt Vector-brand unit I plan to permanently (and safely) connect to my trailer wiring for those occasions when I want to watch TV or have multiple laptops charging or running. Because big inverters consume more energy (whether or not you're using their full capacity) than small inverters it makes sense to use a smaller inverter when that's all you need.

and for those in power challenged areas...

I am using mine right now (Well, not RIGHT now.. it's sort of *nite* out there.. they really stink when it's dark) to keep several small 20 ah batteries going to charge my laptops and have a few lights around the house due to a lengthy power outage.

It's very snowy and overcast here right now, and they are not charging as fast as I would like them to.. but, mother nature holds the cards on this one.

I just saw a Coleman Solar Charger CL-1200 Kit by ICP Solar "The Power to Go" Kit on the web site. It is selling for $139.00, shipping and handling included. (Item # 253599)

Weight is 10.6 lbs.

It says it's engineered to trickle charge 12V deep cycle batteries and power is 1.2A, 15V (18W). It has an LED indicator to let you know it's working. It comes with a charge controller (CC-4400).

What do you think of this model?

For anyone who doesn't want to put holes in the roof, check out the 3M brand VHB tape. It stands for Very High Bond. Someone over on the casitaclub forum has used it successfully to mount his solar panels on the roof. Apparently it can be ordered online.

I actually went down to my Checker store and bought one of these and it is the whole kit. When looking on line for extra 15 watt panels to add on to this I find they are the same price - $99 -as this kit with the controller. It seems like you should be able to get just a panel for less...

Alas, the 2006 $179 Harbor Freight price for the Chicago Electric 45 Watt solar panel kit is now listed as $219 (ITEM 90599-8VGA. Bummer! But wait! The same unit is sold on Ebay in June 2008 for $177 . . . see this link:

The above kit weighs 9.7 lbs. and the panel dimensions are: 12.40'' x 36.42'' x 0.75'' (each panel.) But is 45 watts really enough? I also found an 80 watt panel (not a kit) on Ebay for $335. It's dimensions are 38.9x 26.4 x 1.57 and it weighs 20 lbs.

Here's what the seller has to say about the 80 watt unit:

Brand New 80 Watt 12 Volt Solar Panel From Solar Cynergy with cells from Q-Cells PV-SC080J12

Manufacturer: Solar Cynergy
Cells: Q-Cells
Model Name: SLP80-12
Max Power: 80 W
Open Circuit Voltage (Voc): 21.6V
Short Circuit Current (Isc): 5.17A
Optimum Operating Current (Imp): 4.65A
Optimum Operating Volatage (Vmp): 17.2V

Solar Cynergy photovoltaic modules are designed for commercial and domestic applications and suitable for both grid-tied and off grid systems. Solar Cynergy offers both high performance and reliability. The silicon solar cells, held by heavy duty anodized aluminum frames, are laminated with TPT & EVA for longer working life and high efficiency output. An ideal power supply for boats, traffic signs, lights, pumps, vehicles, RVs, homes, camping and caravans.

Q-Cells wafers are cleaned with acids and alkaline solutions and electrophysically altered. An anti-reflection film made of silicon nitride is applied to them to increase their efficiency. And finally electrical contacts are attached. Q-Cells sells the finished cells to solar module manufacturers.

Admittedly, I know next to nothing about all things electric. However, my brother has an 80 watt panel that he uses for boondocking for weeks at a time and is quite happy with his not-too-skimpy lifestyle out in the middle of the desert. He listens to satellite radio and watches Direct TV shows to his heart's content. He gets all the power he needs for his 22 foot trailer (not a FGRV, but I plan on making him a convert) from this single panel. As for me, I usually meet up with him and bring the laptop camping to work on report cards for 3 consecutive days before I allow myself to go hiking, kayaking, or fishing. If I do the fun stuff first I'd never finish my report cards! But the laptop is a big energy drain and even when I'm not working on report cards I always have some kind of a project in the works. I recently learned from Gina's website that I shouldn't work on the laptop while plugged into the inverter because this draws more juice than if I turned the laptop off and recharged it's battery. I'm trying to plan ahead for the future in terms of what appliances I'll be using on the road. I'd also like to get the TV adapter gadget that goes into the BUS port of the laptop instead of buying a TV for the trailer. Weight is also one of my considerations since my Highlander can only tow 1500 lbs.

So, back to the two panel comparison. . . in term of portability, which seems to be an issue for many, the 45W panel 328sq" larger than the 80W unit but weighs half as much. The interior of my Campster is roughly 6' X 9' so space is important to me. If I had to add more 15W panels to the array to beeter meet my needs I'd be stuck hauling around something even bigger. The 45W unit costs $3.93/watt and the 80W unit costs $4.19/watt, which in my book is a nominal difference. However, the 45W kit includes 3, 6, 9, 12 volt DC adapter outlets; Easy-to-read LED charge indicator; mounting hardware, light, 12V socket and battery clamps. The 80W unit is only a panel and needs all the other dohickies to make it function. The Techie from the Cynergy Company suggested a 10 amp controller at $60, so this would also need to be factored into the equation (but I also got the impression that he was really trying to upsell to me when he told me that a CCFL light equivalent to a 60W incandescent bulb requires 14w of power and since I like a lot of light, he suggested that I get at least a 120W panel!)

Perhaps I have wattage envy. Perhaps I'm overanalyzing things. I'm trying figure out how to get the maximum wattage for the best price without having to tote a lot of cumbersome equipment around in my tiny trailer. Does anyone have any thoughts on the subject? Am I comparing apples to oranges? I have no clue!!!

I've just GOT to get on their mailing list! If I end up getting their solar kit I can pick it up locally and save on the freight charges. I wonder why they don't show it as on sale online? Lizbeth!
