A MUCH better option than the Harbor Frieght 45 watt Solar kit

[mightybooboo]

There is a lot of interest in the HF kit but it isnt the best of quality,so I wanted to put in a kit you can order that IS really good quality. If it scares you and you go HF thats OK too,Ive re-assessed my opinion on that because if it gets you moving on solar at all,then its a good thing,but you CAN do much better at same cost.

The parts I outline below should actually last 25 years,is expandable,and much better bang for your bucks.

This is the Harbor Freight,179.00 dollars,45 watts, and 2 light bulbs.Inverter in pic NOT included.A charge controller thats known as complete total junk that WILL fail and soon

--------------------------------------------------
Instead look at these.The panels are the same that the State of Ca. uses on the roadside emergency phone boxes,and the controller is amongst the BEST in the world,I have em,they are GREAT and hugely reliable,robust and larger capacity than what HF is unloading on you.

4 10watt monocrystalline panels for 100 bucks,25 bucks a piece....

And a 10 amp Morningstar controller for 42 bucks which is world class quality

--------------------------------------
If you want even better Morningstar controller this one has several settings for turning off and on 12 volt lights or whatever,its 80 dollars

MorningStar SL-10L-12V Detailed Description:

The MorningStar SunLight controllers combine the features of the SunSaver controllers (including LVD) with an adjustable automatic lighting control circuit. This allows you to connect a DC light and have it come on at dusk for a set period of time or dusk-to-dawn. It's 10 position rotary switch lets you choose exactly how your DC light will operate.

Morningstar’s advanced SunLight solar lighting controller combines the SunSaver design with a microcontroller for automatic lighting control functions.

This is waaaay better than the Harbor Freight system,can be expanded up to about 160 watts total.Get your own components and get better thats not a beginners medium quality but usable/expandable A1 quality.

I am the idiot trying to learn I need a good book or a writen source to learn more about solar. I am really interested in learning. keep the info going . Now are your currently using solar and how are do you use this stuff. I want solar well pump.

[Jakk]

Do you know of a reliable source for those panels other than Sun Electric? I bought my 200 watt panels from them and I am less than thrilled with their customer service and quality.

Thank you for the information. I've been considering buying the Harbor Freight cheap-o system just to get started experimenting with solar. I think it's on sale for $150 this month, but for the same money I'd rather go with something that works well and will last. Thanks again!

Yes,I have several small 100 to 400 watt solar systems going.

The alt energy forum has the info you seek.

A brief explanation on hooking up a tiny system like the 40 watter.

Each panel has a + and a - screw. From each panel run a wire from the plus (positve) to the next panels +,when all are connected do the same on the - (negative) lugs.

Now from the last panel connected run a positive wire and a negative wire to the controller and screw em in where it says solar. Where it says battery you run a pos and neg wire and hook it to your battery.You would add an automotive fuse on your positive wires but for now dont worry about it.

So now you have the panels hooked to the controller which regulates the voltage charging the battery.And from the controller the wires to the battery so it can be charged.

From this point run whatever 12 volt item you want from battery.

Want to run 120 volt items then you need an inverter. They come in sizes from 50 watts up to thousands of watts,for this tiny system you would use something like this that connects to the battery posts,the ones with little clamps to connect to battery are easiest but again,no biggie,we are talking theory and whats involved.If you ever go this way the Alt Energy forum guys will walk you through it,its SIMPLE,remember that,simple.REALLY simple if you have ANY mechanical ability at all.

Something like this....19 dollars
http://www.google.com/products/catal...d=0CH4Q8wIwAw#


This shows how to get the connections for your 120 volt power from a 12 volt battery,,of course a tiny system like we are talking is only suitable for running items that dont exceed a couple hundred watts of 120 volt power.Wouldnt run that microwave with this little system.

I checked out the link, but all I could see was the pallet price is $2.50/Watt. Am I missing something?

[mightybooboo]

Nothing wrong with starting with the HF kit as it is super simple to plug together.But if you can screw in your own wires instead of plugging them together,there are better options than HF.

As for sunelec never bought from them but the guys at alt energy forum have and are over all pleased with the super prices.

[mightybooboo]

Hmmmm....this page says minimum order is 2?

I had thought about the Harbor Freight panels, but husband says they're junk, that the silicon surface is very thin, or something to that effect--that the surface that catches the light is thin and won't last.

FWIW, I know very little about solar, but I think I'm going to have to learn pretty darn soon. Had to laugh---now the last picture, I CAN understand!!

Husband has extensive electrician experience, which is good.

He's about to start scrounging up parts for a small wind generator.

Thank you for posting this topic!

Can you tell us more about that,I sure want to know,I know others have been pleased with them so your story would be much appreciated.

And for the happy folks,your stories too?

[kasilofhome]

Thank you the dots conected for me. Now I have a better understanding. This is great becasue our siduation is that we have the cash to do this and it is a long term asset goal that will reduce the need to spend cash thus increase the pool of money for property taxes in the future.

[mightybooboo]

Julia,I agree with your hubby 100%.

The little panels I show are monocrystalline,meaning they have thick individual solar cells.12-14% power output per size,VERY good number.

Its the oldest tech,the most proven tech for durability,and the most power output for size of cell.They used em on satellites in space and they held up.

The downside is cost.They cost more to make so usually cost a little more to buy.

They are my favorite panel pick by far.

I also have some multicrystalline,they are the shiny blue panels you see,next best choice and also very robust.Fine quality with a name brand panel.

The HF,Im not sure exactly what they are,but they appear to be these and I wouldnt buy these at present,no track record and durability unknown,though have seen some very early power loss rates on some...

http://www.solarpanelcenter.net/Type...lar-Panels.php

-Amorphous Silicon Panels – Amorphous silicon panels have the lowest electricity return rate of any type of solar panels. Traditionally amorphous silicon solar panels have an electricity return rate of between 5%-6%. That’s because these panels aren’t made with crystalline silicon. They are composed of a piece of semi conductive metal, like copper, with a thin silicon film over the top that is attached to some metal pieces.

These panels are very cheap to produce but when you’re buying solar panels for home use you need to consider the long term efficiency of the type of panel that you’re buying. Unfortunately, though cheap to begin with they do not produce much energy, therefore amorphous silicon panels are not going to be cost effective in the long run.

If you want to see my trucks 320 watt system its at solar gary's site.

Dont let it scare you if you are a total newbie to the idea,stick to the simple one we are discussing.

[mightybooboo]

How a small system hooks up,click on the pictures to enlarge

First thing to do is hook the 2 panels together.Wire the positive to the positive of each panel together and add a pigtail wire to go to the charge controller.Same story with the negative wires.Im using 12 ga wire because its such a short run to controller

CLICK TO ENLARGE PICTURES






Flip the panels over....We are using the 2 panels on the left (180 watts total of 12 volt panels),the 3 on the right and above will be used on a different system to charge the battery bank that powers the house during power outages






Run wires through wall...




And mount the Charge Controller.This doodad controls panel output to get maximum charge rate from panels while avoiding overcharging battery




Now make wires to run from battery to charge controller




Oops,forgot to wire inverter to battery.This device changes the 12 volt DC battery power to 120 volt AC household power

Connect those battery wires then run them up to the Charge Controller




Now Connect the wires from the panels to the Charge controller.One should be ideally black (The 2 wires on left) But I have a lot more red wire so red it is.I did mark the end of the negative wire with black zip ties to tell it apart.Also note there should be a fuse in both the panel and battery circuit,I will add later as I didnt have handy.Regular 20 amp automobile type fuse is fine.




There we have it,all hooked up and devices plugged into the inverter receiving 120 volt AC power




Running a fan,a CF Light bulb and a string of LED lights in the 'barn'

[mightybooboo]

Added 20 amp fuses to battery line and solar panel line as its a 20 amp 12 volt Morningstar Charge controller...

The 2 wires on the left are coming from the solar panels.The 2 wires in the middle go to the batteries.The 2 wires on right go back outside and power the porch light as this controller has the optional light control circuit.




6 Deka batteries and small inverter,6 more Dekas coming hopefully....




Inspected and passed by 'Code Enforcement' aka dog...




.............

[mightybooboo]

I use the small system for barn power,and outdoor light

My Latest project,all from Thrift Store parts so dirt cheap.I have no idea cost,last basket was 28 dollars and included 2 of the 35 watt tractor lights and the bracket.

I bent the bracket into a shape I liked...

Click to enlarge pics,lower resolution pics so dialup friendly



Run wires through wall to Charge Controller timer circuit,they are the 2 wires on Right.See,solar even loves me,wires are an upside down heart,LOL!...2 left wires to solar panels,2 middle wires to battery,2 right wires to light,Durn simple isnt it?






All wired up...




It works! All set up to run 3 hours after dark and 1 hour before Dawn.That Morningstar Controller is fine!




Im sure Mrs will paint it up real cute,but pretty cool light,eh? I went out at night and it lights the whole backyard,Nice! And on free sun power,gotta love it!

Thanks! I tried to find it myself, but I failed.

Mightybooboo....
I bought a 200 watt panel from Sun Electric and it came with a burn spot on the panel. I called the company and they basically told me it's fine, not an issue. Hooked up the panel, it didn't work. I called them back and they said to me "What do you want from me, it doesn't work, you must have hooked it up wrong." Umm, no.. I called you when I first got it, before taking it off the pallet, and told you there was a burn spot. It did not happen because I hooked it up improperly.

I get back on the phone, got the run around from one person to another. They put me through to the shipping department and finally argue with them enough that they agree to send me another panel, at their cost.

Waited and waited, no panel. Several calls later, they finally ship the replacement panel. I opened it up IN THE DRIVEWAY, infront of the delivery guy, and guess what... a burn spot on the panel! I told him to take it back, I don't want it. He wouldn't put it back on the truck and told me I had to call the company to have them ship it back, or I would have to pay for the shipping.


I called Sun Electric back again and they get nasty with me. I told them they can call the delivery company to verify that I opened it in front of them and it was damaged. Then they tell me to ship it back to them, at my expense. I wrote a letter to the head of the company, got no response. I wrote again, and CC'd every person listed on their website. Finally got an email response and was again told to ship it back at my expense. They refused to pick up the two damaged panels and refused to send me a properly working panel. I refused to pay to truck ship the two damaged panels.

So I cut my losses and now I have two panels that are burnt and do not charge anything. I am very unhappy with the company. I could not believe they sent me a second panel without checking to see if it was damaged or not.

[mightybooboo]

Wow Jakk,thats mighty poor dealings!

Let me get back on some different panel options,doesnt have to be 10 watters....Could be a single 40 or 60 watt,let me update later with that option.

[debbiekatiesmom]

this is just what i was needing to learn about! had been considering hf panel, too! any and all info you can give would be fantastic! thanks. step by step for dummies like me! do they have a book "solar power for dummies" out??
