45 Watt Solar Panel Kit

Who Are They For

Harbor Freight Solar 45 Watt Panel Kit #68751 W/ 2000 Watt Power Inverter

Since smaller options like 45-watt and 50-watt solar panels can power low-energy appliances, theyre best suited for portable needs.

If you find that youre forever frustrated with your phone dying on a weekend camping trip, or you want to keep a few beers cold when you go fishing, then these options could be perfect for you.

While you can certainly power your whole house by connecting a series of 45-watt panels together, we wouldnt recommend it. Smaller panels are less efficient than larger ones in terms of their power output per square foot, and theyre going to cost you a lot more.

That doesnt mean that smaller panels arent good for at-home use, though. If you live in an area thats prone to power outages from bad weather or storms, a 45-watt solar panel is great if you want to keep the lights on.

If you connect a small panel to a battery pack, you can keep multiple appliances running when the rest of your neighborhood is in darkness, even if it takes a while to fully charge it.

A Quality Alternative To The Typical 45 Watt Solar Panel Kit

Implementing solar power has traditionally been an expensive undertaking and, though prices have improved substantially in recent years, the tendency from the customer’s perspective is still to think about solar power in terms of the cost. That is still a somewhat justified perspective if associated costs are a significant factor in the decision to go solar. Those homeowners who must consider costs when deciding whether or not to install a solar power system on their home cannot be blamed for bargain-shopping.

But there has also long been a tendency on the part of solar energy hobbyists and do-it-yourself solar enthusiasts to shop for bargains, leading them to purchasing products that do not hold up over time. As a result, they end up with DIY solar kits that often fall short of expectations. Sure, they’re useful to an extent. But those who purchase consumer-grade solar kits often become disappointed in the parts and power output of these consumer-grade solar kits. Granted, there are applications for which these kits fill a need.

What is it?Solar panel kits allow you to generate clean, quiet energy using the light from the sun to operate DC appliances or recharge 12 volt DC batteries or, when connected to an DC-to-AC power inverter, to power TVs, lights, computers.

Here are some examples of issues people are finding and reporting for one of the more popular consumer-grade kits, the Harbor Freight 45 watt solar power kit:

BayareaBill said: I saw the sale ad and I think it is a coupon price so I don’t think HF will take 2 coupons on the same item,but worth a try,I put 2 sets of these on top of my Class C to charge a set of 6 volts that power my C-pak and a TV in the evenings,on a sunny day it pretty much replaced the amps?back into the battery’s,that’s with them laying flat,and I was in Washington state in the fall.If budget is an issue,this could be a good deal for you,my cost /2 sets of panels 325.00,quality charge controller-100.00/aluminum hardware for mounting and misc wire,connectors and such another hundred.about 8 hours to install.I have 2000 miles up and down I5 and didn’t lose or get any breakage from road trip.If you do go this way and want them hard mounted get back to me as I came up with a pretty clean install that didn’t require any unusual tools or skills.

Connecting The Battery And Lights

The final step is connecting the battery. I went ahead and connected to a marine battery I had laying around and before I turned the controller on I disconnected the solar panel just to see what the voltage was. It’s pretty low – 9.8 volts but it’s also a very discharged battery

Next I connected the solar panel back up and the battery reached 12.8 volts pretty fast. This is a good sign for the solar cells – they are producing power. But it looks like I’ll be replacing this battery because the voltage should not have come up this fast!

Once I had charged the battery for about an hour I tried the lights. They seem to work well.

Adding A Harbor Freight 45 Watt Solar Panel To My Storage Building

Earlier this year we bought a 10′ X 20″ storage building and had it delivered to the backyard. The storage building is great – I’m slowly moving things from my garage to the building, I’m doing this slowly because at the end of the day I don’t want everything thrown in the building – I want some organization.

One problem with the building is long before it gets completely dark outside it’s so dark inside that I can’t see anything. It’s cost prohibitive to run power to the building so I decided to do the next best thing – solar powered lighting. For an application like this you really don’t need a lot – you need to collect enough solar energy to turn on the lights maybe 15 minutes when you need them? But you also need enough energy to carry over cloudy days.

Also, my direct view of the sun is limited from the roof of my storage building by trees so I figure I’ll get an hour or two of good strong sunlight a day. This meant that I probably could not get away with a small 15 watt solar panel.

I ended up buying a Harbor Freight 45 Watt solar panel kit and you can find my full write-up of this kit in this instructable.

I Bought And Unpacked The Harbor Freight Kit

I finally had about $200 to spare and I bought the Harbor Freight kit. My first surprise was how heavy this kit was – it’s almost 60 lbs!

Next I unpacked the solar panels – each solar panel was protected by a pair of styrofoam panels. I also discovered why the box weights so much. The solar panels are very heavy for their size.

The next surprise came when I unpacked the tubes that assemble into a frame. I expected some cheap thin PVC tubing. What was in the box was still plastic but the plastic was very heavy. Also, everything was clearly labeled.

The other major parts – the controller and light were packed in a box inside the main box and the interconnect wiring was in with the plastic frame parts.

How Does The 45 Watt Solar Panel Kit Work

The kit consists of three 15 watts 12-volt amorphous silicon solar modules. The panels deliver a combined output of 45 watts.

You have to assemble the frame. After assembling the frame you mount the three panels onto the frame.

Bear in mind that it is easier if you attach the middle panel first. Other than that, you have to follow the instructions.

Align the panel mounting holes with the top and bottom mounting holes of the frames.

You then use the screws and nuts to secure the panels to the frame.

Now you attach the three leads from the 15 watt solar panels to the splitter cable.

Next, it is time to connect the splitter cable to the extension cable. After that add the extension cable to the charge controller.

Now you connect the battery terminals to the charge controller.

A large LED display on the front of the charge controller will show the voltage. You will know immediately if everything is working well.

Bela said:The Renogy kit mentioned above appears to have a 30 amp charge controller. If you plan to add panels in the future, this would be a good deal as you would not have to buy another charge controller unless you go over 400 watts of solar. Also, they are made well and have a great warranty.I have Renogy panels and the 30 amp controller. Work great and customer service/techs are very prompt and helpful if needed.

Optimistic Paranoid said:Do you know – or can you make a reasonable guess – how many amp hours you are going to pull out of your house battery on an average day?Depending on your answer, you might still need to tie the engine and house batteries together and charge with your alternator.45 watts divided by 12 volts is 3.75 amps. Depending on where you are and how much sun you get, you MIGHT get 15 to 20 amp hours out of this system. Maybe less.The cables are probably the thinnest – hence cheapest – ones they figure they can get away with. The charge controller will probably need to be replaced with one that can handle more power, IF you need to add more panels in the future.The panels and mounts are probably the only usable things you will be able to keep if you need to expand the system.Regards

The Advantages To Be Associated With The 45 Watt Solar Panel Kit

  • The Amorphous silicon solar cells ensure efficient output in bright and cloudy conditions.
  • Flexible and easy to handle. It is also very easy to change the tilt angle for increased exposure to the sun and increased efficiency.
