We often get asked by OutsideSupply.com customers about easy ways of installing solar chargers in remote areas. While there are many ways to get this done, I usually find a Lean-to type installation to be the easiest for on ground mounting. If you have a clear south facing area where the panel can be placed on the ground without damage and shading then this may be a good choice for you.
*** Remember a leaning panel will be broken if stepped on, climbed on, or pretty much anything happens on the panel. Do not use this install if you have any issues with the aforementioned installs.
Here is what you will need to get started on a Lean-To solar installation of our 10 Watt Unbreakable Solar Panel
1 10 Watt Unbreakable Solar Panel
1 2X4 Treated
2 Stainless Steel Screws
2 Stainless Steel Washers ( Large Enough to keep screw and washer from going through grommets.)
You will also need proper charge controller and battery for charging.
OK this process takes a little math and also some wood cutting. If you are not familiar with the math, we found a site to help. If your not familiar with cutting wood, get someone who is to help you.
First Calculate the angle you need to place the panel at to achieve the best charging. I like to calculate for making a winter mode and summer mode set of Lean-To legs. If you can only use one set then do a winter mode set.
A quick rule of thumb is to have your panels lean (Your Latitude - 15 Degrees SUMMER) or (Your Latitude + 15 Degrees WINTER) More Exact information can be found here at the Optimum Orientation of Solar Panels page written by Charles R. Landau. He has made a very detailed approach at the getting the best angle for optimum efficiency.
Once you get the angles need you will need to calculate the length of the legs and also the angle to cut the 2X4 .
Right Triangle Angle And Side Calculator
Here is my example:
New Orleans is about 30 degrees
Summer Legs 15 Degrees
Winter Legs 45 Degrees
Plug the length of the panel into the above calculator.
(SUMMER)
20" for side C (10 Watt Panel Length)
15 Degrees for Angle A or B
Side A is 5.18 Inches on the longest side.
It will also be cut at a 75 Degree Angle.
(WINTER)
20" for side C (10 Watt Panel Length)
45 Degrees for Angle A or B
Side A is 14.14 Inches on the longest side.
It will also be cut at a 45 Degree Angle.
There are two grommets on the 10 Watt Unbreakable that I use to screw directly into the wood. I use a nice size Stainless washer and stainless steel wood screws.
