Solar Angle Guide, Panel Accessories for Precise Angle Adjustment to Improve Energy Conversion Efficiency - for Portable and Foldable Solar Panels, Battery Charger

I got this to use to line up my solar panel so that I can capture the most amount of sun at various angles. Simply clip it on to the solar panel and line up the sun with the center dot - works every time!I then had trouble lining up my telescope with the sun for solar observing - including the eclipse and this worked! I was so happy I thought of it. I am able to use it to line up my telescope with the sun and it makes finding the sun sooooo much easier. You would think it is easy to locate the sun, but when the solar filter is attached, everything is black and you really cannot find it easily.Get one if you have a solar panel or a telescope to angle towards the sun

I'm building an automatic solar tracking mount for some solar panels that I picked up a couple years ago. However, in the meantime, getting those panels pointed directly at the sun is guess work at best. When I saw this SUNSUL Solar Angle Guide, I just had to try it out.Unboxing: The small box contains the Solar Angle Guide unit, a screw mount that you can clip the guide to, and the owner’s pamphlet.Setup: Because of the metal frames of my solar panels, using just the clip to mount it would put it at the wrong angle so I will be using the screw mount. In the middle of the clear dome of the guide is a small indent that is used to cast the shadow onto the target map on the bottom of the guide under the dome. Angle the guide so the shadow sits in the bulls-eye of the target and you are pointing directly at the sun. Clean, simple, neat and uses no power.Using: I found that coloring in the clear indent with a black marker (see attached image) makes a more prominent shadow on the target and (at least for me) made it easier to align the target with the sun. I also found that the sun's reflection on the dome itself also lines up with the bulls-eye of the target at the same time the shadow does so there basically just bring the light (sun's reflection) and the shadow together and you're also pointing directly at the sun.Results: This is so simple, it's fool proof. The unit is small (about 2" across) and very light since it's plastic, but it is sturdy so unless something heavy falls on it (I'd be more worried about my solar panels), I think this thing will last a very long time. I rank the SUNSUL Solar Angle Guide with 5 Stars.

This little clip-on (or mountable) angle guide is very helpful for figuring out how to position my GoLabs foldable solar panels to be sure I get the most juice going into my solar generator at different times of the year. You can search online to find the very best angles for the sun for your location and time of day/year, and then it's just a matter of using this angle guide to get the sun's focus into the ballpark. If you want to babysit it all day, you can, or you can just determine what your ideal fixed angle is for your region.I like how the little clip works alone with my thinner fabric-edged panels without tearing them, but also that I can snap the clip into the mounting braket for mounting solidly to a larger panel mount. It seems pricey for something made out of plastic, but it's good plastic and should last a very long time. It's value will demonstrate itself over time as you use it to precisely adjust your panels.The instruction sheet is useful. The only thing I would recommend they do to improve this product is either make it with permanent UV-resistant black circle-lines or include some kind of blacking gum that can be rubbed into the markings to make them more visible. I will probably try to use one of those black paint pens and see if I can mark the gradation lines so I can see them.

This is a pretty neat and simple device for aiming solar panels. It can be used with both portable cloth panels and solid glass-covered panels.My main problem with this is that it works by focusing light into a small point on an opaque white surface. Unlike how you’re not supposed to look at the sun during a solar eclipse, this thing makes a single spot brighter than the surroundings, that you’re supposed to look at to aim the panel correctly. This doesn’t seem safe to me.

I live off grid and rely on solar panels for all of my electricity. It is so difficult to find the correct sun angle. I have tried angle tools used in construction and I just end up confused by them.Right now, we have almost no sun so I have not been able to install this, but I can't wait. This is going to be awesome.I used a flashlight in the pictures to show how the light goes through the hole in the top and places a dot on the angle grid inside the tool.When we get sun again, I will be able to go outside, line these up with my solar panels, get the time of solar noon for that day and readjust my solar panels to give me the maximum amount of sun possible.Thanks for a great, easy to use product for those of us that are not highly trained solar installers or scientist.

BOTTOM LINE:1. I recommend this solar angle guide.2. Easy to use. Good to train your own eyes for the best solar angle.3. Easy clip on and use. Markings could be better contrasted for easier use.THINGS YOU SHOULD KNOW:The solar angle changes continuously. This handy solar guide will help you find the right angle at this moment in time. Over time, you will learn to over adjust the angle a bit, and then correct it after the angle has become optimal, and then progressed to non-optimal, saving the number of adjustments you make.UPDATES:None at this time. I will update this review with any changes or important additions should any arise.
