Review by Mr. S. Clark:
I ordered this but although the two panels and mouting kit were present the packing was inadequate and well battered – being only very thin fibreboard for something weighing 60 pounds and no proper bubblewrap of panels. A corner of the packing had broken open. It would seem the charge controller and and inverter are missing. The panels seem OK but I would advise purchasers to inquire as to packing. Maybe Amazon need to charge 20 dollars more for packing. Howevever good value if enventually I get everything!

Sunforce 50044 60-Watt Solar Charging Kit Reviews

Review by HMMWV:
Update 9-18-2008 – Still going strong. I am very pleased with the summer power output of these panels. I wash them with a hose 1x/mo to keep the output current up. Measured before washing and after washing the panel efficiency is clearly a factor of how much dirt is on them. No problems long term on a roof though!

Update 2-20-2008 – goes with graph “photograph” #3 above – pink line is power and blue line is amps from the panel x 10 to share the graph. The X axis is panel voltage. Data was acquired using an Agilent dummy load with programmable voltage in 1V steps from 1V to 22V (open circuit voltage on the panel) on a partially cloudy day in winter sun. Expectations are for 2-3 times performace in summer sun provided the panels don’t get too hot. These are on my house roof laying flat on a 3/12 pitch facing due south which is suboptimal but easy for me to do. Be sure to read the photo notes. Sorry about the colors excel defaulted to!

This is a MPPT chart (maximum power point tracking) – you can see that the panels are optimized for charging a 12V wet cell right out of the box. Charge current turns on when battery voltage drops down to 13.0 VDC and turns off at 14.2 VDC with the supplied charge controller in the kit.

The only other interesting fact in 2 months is to keep your panels clean. My maximum current was 5.0 A on a cold morning with bright sun until it rained hard and washed the panels clean. The current went up to 7.0 A maximum right after the rainstorm. Below is the original review – these panels have been running constant for 2 months now into 3 parallel deep cycle marine cells (315 AH) connected to the prosine inverter below to drain the energy made.

When reading the power/current chart you should keep in mind the amps have been multiplied by 10 so they use the same Y axis (so 20A on the chart corresponds to 2.0 A panel current) Watts are actual volts*amps. This was taken in the winter with partial clouds – expectations are for a X3 improvement during summertime but its still february and I’m in the northern hemisphere so we’ll have to wait and see. Basically an MPPT charger won’t gain but a few watts with this panel so it’s not a good investment unless you already have one laying around.

(Begin original review after buying panels)

I never seem to be overwhelmed by the latest shipment of product from China, but this one seems to show some promise and shows signs of good cost engineering and a complete design that can be set up quickly by one person with very little effort. I’d give it 5 stars if it were well packed, but my purchase turned into a shipping fiasco.

Most ALL solar installations are rated in $/watt much like new homes are rated in $/sq ft. We’ll get to the sq ft bit later. Here you are getting 60W for 320 dollars or about 5.33 $/watt. Compared to a similar wattage panel, the BP solar 365U rated at 65W and priced (street) at 399 or 6.13 $/watt the amazon package seems to be a good deal when you consider it comes complete less battery (we’ll hit that one later too)

In fact, the amazon package deal includes a xantrex 175 watt inverter with a .15A “idle” current designed for solar systems where current consumption must be minimized. It even includes a simple diode/switch “charge regulator” with 2 leds to indicate panel voltage and battery is full but lacks the ability to tell it what type of battery you are using (full is defined at 14.2 volts give or take so it’s for wet/flooded cells). Neither of these are big buck items, but they do set you up for a complete small scale solar kit minus the battery out of the box, which is impressive.

Oh yes, the battery. I also ordered the duracell 480W inverter+28AH battery with this panel so I’d have a battery. Also made by Xantrex, it’s a nice piece to complete the system. I made the mistake of ordering it with the solar panels (read on)

So how does China produce a complete kit for a lower $/watt price than professional solar companies like BP solar, GE, Kyocera, etc? Well – it’s the sq ft part we forgot about for a while. This uses 4 panels @ 15W each to get up to 60 watts with a simple parallel adapter included in the kit. The BP solar is one panel about the size of 1 of these 15W panels, or put another way, is 1/4 the sq footage. So if you are planning on covering your roof with these, think again because you’d need a really big house and have lots of 7A charge diodes and 175W inverters kicking around when you are done. The reason for the 4:1 size difference is the China panels are made using a silicon deposition on glass technique with a very thin film and correspondingly thin output, while other manufacturers use a silicon wafer production method that is roughly 4x more efficient in area, and somewhat more expensive as a result.

Ok – now onto packaging. We need to get this from China to Amazon and finally to the consumer. On the first attempt FEDX carefully placed my fragile glass solar panels on the concrete then put 2ea 60lb batteries on top of them, cracking the glass on all 4 panels. After returning that to amazon, we tried again, this time without the batteries and shipping the system by itself. FEDX again noted shipment damage which wrecked 1 of the 4 panels, but running on 3/4 panels it does work, just not with full output. Amazon has given up because they will only ship and ruin something twice instead of making fedx pay up for piling 120 lbs of batteries on top of the glass panels and poking through the box & styrofoam the second time so I am still in negotiation with them about the shipment, however the product does deserve mention while I have it.

PERFORMANCE:

The design is actually quite well done. You can make (with 4 panels) a 12V (actually 15V) x 4A system, or a 30V x 2A or a 60V x 1A configuration depending on your power inverter and battery collection. For me, this will always be tied into a 12VDC bus so it is fine as shipped, but the flexibility is there if you have other voltages in use. There is no skimping on wire with 16 foot cords on each panel which helps to minimize power lost in the wire since each panel has its own cordset going to the combiner, after which runs are kept short. On a cloudy day I was able to get 2 amps from 3 panels (30 W) – in full sun it peaked at 5.91A with 3 panels, so the Chinese manufacturing has under-rated their output as 90W from a 1/4 dead 60W panel in winter sun is doing very good – I’d like to know how it performs in the summer!

As for mounting, a very clever system was designed to support the panels out of 1″ PVC tubing with elbows and T’s – all of this is assembled with a singular bolt/wingnut style and the pipes have slots milled into them to ensure that the panels will line up one way or another without breaking after you get them. It has a prop-up leg system for use on the ground or can lay flat if placed on a roof that is already angled towards the sun. There isn’t a provision for connecting multiple systems together, however you could make one out of sprinkler pipes you probably have.

All this really needs to be a well designed solar kit is 1) better packaging and 2) a battery. Even with 25% of my panels broken and removed from the system, it still managed to charge a car battery in under 1 cloudy winter day.

I’m impressed with the product, however disappointed with the shipper. I’ve also run up against Amazon’s policy of two strikes and they are out meaning they won’t negotiate for repair or replacement as the shipper on my behalf. I can return it alltogether or pay 100% for 75% of a system so it’s probably going back tomorrow (monday) – but my testing this weekend has shown that the product warrants consideration for people who

A) Need to keep their starting batteries charged year round (2nd cars, generators, etc) outside where AC power is not convenient.

B) Do not have A/C power at all and would like to run a small refrigerator (purchase a Xantrex Technologies Prosine 1,000 to 1,500-Watt Power Inverter #1000 TRUE SINEWAVE power inverter to run any motor load without damage)

or

C) Have lots of roof space and are looking at the lowest cost/watt installation complete with mounting hardware.

Don’t forget the battery – and don’t have it delivered with your solar panels. As for emergency power, 60 watts won’t do much for you but keep your generator battery charged and ready to go when the power fails. My natural gas genset is rated for 12,000 watts or 200 of these 60 watt 4-panel kits (800 panels) which would cost ,000 and still not provide power at night, like the quiet genset does. With 12,000 watts I can comfortably run my whole house. Considering these natural gas gensets can be had for under 00 they are clearly the best solution for whole house power backup systems.

My use was to keep my seldom used 12VDC batteries all charged in the back yard. Regretably, amazon’s lack of proper packaging and refusal to negotiate with FEDX over damage means I’ll probably put in a 12VDC charger inside my house and run the low voltage 12VDC wiring outside to the batteries that need a trickle charge.

One last reliability issue – having seen 5 broken panels now I can see an advantage to the professional panel systems – these use the glass just as a cover & weatherproofing plate. The cells underneath are not damaged if the glass breaks. On the amazon system, the cells are deposited on the back of the glass, so if it breaks, by default so does the entire cell.

Review by C. Bayne:
We bought this a few months ago. We live in Phoenix, AZ (”Valley of the Sun”), so this has plenty of opportunity to work. We have it plugged into 2 marine batteries (like car batteries, but bigger), and we have an inverter connected to those. The inverter is in the house, and the batteries are outside. The wire goes through the wall. We plug things into the inverter.

This was easy to put together. You have to buy the batteries, but this came with everything else.

I can run my laptop all day, as well as recharge the cell phones and Wii remotes. My husband can also run his laptop. If we only get on the laptops after work, we can run them well into the night. I’ve had to switch to grid power a couple of times if I’ve used my laptop all day, but I’ve never had to switch over if I’ve only used it during the evening. (This doesn’t count the few rainy days we’ve had. Yes, once in a while it rains in Phoenix.)

This is not the most efficient solar panel set, but it’s very good for starting out and learning about solar power. It’s inexpensive enough to set up and charge all your rechargeable stuff whenever you need it, as long as you live in a fairly sunny area.

Oh, as an experiment, I plugged the vacuum cleaner into the inverter, which promptly started screaming for help. (The inverter has an alarm, apparently.) This whole set-up CANNOT handle this kind of power draw. You have to unplug everything and turn the inverter off and let it just sit a while and reset before plugging in your lower power things again.

You’re not going off the grid with this set-up, but you’ll save yourself a few bucks a month. And you get to be smug whenever anyone talks about going green. “Well of course, our solar array has lowered our carbon footprint considerabley. Shall we go for an organic smoothie now?”

Review by Amanda Richards:
This one may be tossed – tomorrow

Bet your bottom dollar

That tomorrow, it’ll be gone

Just thinking about, tomorrow

Clears my brain from cobwebs and much sorrow

It’s no fun

When I’m stuck with a toy that’s lame and boring

I just stick out my chin and grin and say, ooooh

This kit will be tossed, tomorrow

So I gotta hang on `til tomorrow

For trash day

Tomorrow, tomorrow

I love you, tomorrow

You’re only a day away

Okay, maybe a slight exaggeration there, but really, this toy can’t hold a candle to the Snap Circuits Jr. SC-100 Educational kit by the same company.

For starters, this one requires a screwdriver and spanner to set up, and it’s extremely unlikely that a typical eight year old will be able to do the (few) projects without adult help. The instruction manual begins with line drawings and schematics for connecting circuits in series and in parallel, and continues with the calculation and formulation for such things as “how many rows of solar cells are needed to make a solar panel work for a solar musical unit of 4.5V 100mA”

After they make your head spin (without the help of a solar panel), when you get to page 10, they helpfully add “If you do not want to make any calculation, just skip and follow the simple instructions below”, which is followed by a series of black and white illustrations with captions like “No.2 screw connected to No.4 screw with jumper wire”

After you get all this done, you need to ensure that the panel is in direct sunlight. You can apparently use a 100W bulb 5 inches away from the panel, but only for 3 minutes, as the heat may melt the plastic frame. (!)

We connected the panel to the motor and fan today, and put the panel on a sunny window sill. I’d like to say we were blown away, but as the kit includes no form of storage for the charge, every time a cloud passed over the sun we were out of the flying fan and into the fiery heat of the day.

You can also connect small appliances depending on the required voltage and amperage (up to 4.5V or up to 300mA), but without a battery and charge controller it won’t be very effective.

While this kit has the right idea at heart, they need to work on the presentation (looks cheap), the ease of set up for the target audience (from 8 years old), the instruction manual, and above all, they need to offer a complete solar set-up that can actually make the projects work effectively.

This one is not likely to be a favorite for anyone of any age

Review by Xilipden:
I bought this solar educational kit for my son 4th grade school science project. After reading the reviews from the others, I was skeptical about the product. Since this is the only solar educational kit on Amazon and the price is reasonable right, we decided to buy it. We received the product in two days. The instruction is straight forward and easy that my son can do it by himself without my help. We also bought the spot flash light for about from Home Depot to use it as a sunlight for indoor. This worked really well for the fan, but for the light bulb you need to use the sun light as well. Overall, this product is good for young kid science school project. My son really enjoyed it.

Review by Scott:
If the Xantrex Xpower Powerpack Solar lived up to its specifications, I would rate it 5 stars and consider it well worth the money. That’s why I bought it in the first place. Unfortunately, its performance falls short of the manufacturer’s claims.

The overall design of the product is very nice. I had considered building something similar based on a how-to article in Popular Science, but the Powerpack is so nicely packaged for only a couple dollars more, I chose to buy it.

The Powerpack disappoints in the amount of energy stored in its battery that is available to power other electronic devices. The battery is specified as 12 volts and 10 amp-hours. As such, I was expecting to get as much as 120 watt-hours from it, but I barely get half that.

As a test, I fully charged the battery using the included AC adapter. By “fully”, I mean the unit claimed to be charged. I then ran the built-in LED lights. The manual claims they should run for 48 hours. They ran 27.5 hours for me.

I assumed this performance reflected a bad unit and exchanged it. The new unit performs similarly. Either the battery in the unit performs poorly, or the electronics to monitor and control the battery state-of-charge are weak.

As another example of the poor performance, I charged the unit completely (again based on its built-in indicator that charging is done). It indicated 100 percent charge when I turned on the AC or DC output, but as soon as I plugged in any load, it almost immediately dropped to 70 or even 60 percent. Soon after the unit’s indicator dropped to 40 percent, the unit shut itself down.

So, on the one hand, this is a nice unit to carry around, and it does slowly-but-surely charge the internal battery using the included 5 watt solar panel. It does a fine job charging cell phones and iPods, and a barely acceptable job charging a notebook computer. Compared to its specifications, and for that matter my previous experience with the Xantrex Powerpack Mobile Mini, however, the product is a disappointment.

Review by J. Gabrielli:
The product information should include these crucial tidbids, which you only find out AFTER buying (by reading the detailed owner’s manual): 1) you cannot use it while you are charging it, and 2)if you want to charge it using the sun, it takes 45 HOURS (YES — that’s HOURS). I used it at an outdoor festival to power a laptop, and — even thought the manual estimated it would last for up to 4 hours, it pooped out after 1.5 hours. After that, I unplugged and charged it in the sun for a while. It got a lot of interest from people at the festival, who thought it was cool. I think it’s cool too. I just wish it worked better.

Sunforce 39126 246-Watt High-Efficiency Polycrystalline Solar Power Kit Reviews

Review by Ollie:
Rather than pulling out a generator and electric cord for daily charging of my RV batteries I decided to purchase this set and hoped it would supply all my electrical needs while camping. It does, very well. I took the advice of another poster and purchased a more efficient charge controller separately, the Morningstar MPPT and it’s display panel. The MPPT controller increases the charging efficiency by up to 30% or more. These solar panels now easily keep all 4 of my trailer batteries charged and recently averaged at least 10 amps of charge for each daylight hour. I searched all over the web and Amazon had the best price on this particular set, or anything like it. The money saved is enough to upgrade the controller for more efficient charging. The set came with nice extras like a 200w inverter, voltage test gauge, plenty of wire and 6 mounting brackets per panel.

Solar Power Your Home For Dummies (For Dummies (Home & Garden)) Reviews

Review by J. H. Petrescu:
This is a good introduction to how the energy from the sun can be put to practical everyday use. If you don’t like to read a lot of technical stuff, this book is for you. Quick, easy reading the non-technical average person. with references for more information. This book has practical projects for the person who already has some knowledge of solar energy as well. If you’re looking for a really detailed technical book of how to design and install your own solar collector (electrical or water), better get a different book. My 5-star rating is for those who are beginners or those that have a little knowledge of solar energy.

Review by E. California ‘tron-pusher:
As an electronic engineer, I originally looked at home solar energy as a chance to buy some cool gear to play with, while saving money in the bargain. As I delved into the book, my outlook changed. I was surprised to find how complex a home’s energy use situation can be, and that some money can be saved before connecting a single wire. Even as I later relished the chapters covering solar electricity generation, I still noted the frequent reminders and references to non-electrical aspects of a “solar” home, as well as practical financial and regulatory realities to consider in choosing a system. In short, I came away from my first reading with a much more balanced perspective on solar energy, and I’ll continue to re-read as a reference. Of course, I’m still hankerin’ after that gear, yet, at least, now I have a better picture of what’s really useful. Plus, I’m off to a good start in being knowledgable enough to deal effectively with those installation contractors. Well done!
