Over dashboard solar panel reflections

The white borders are visible on the windshield.
The reflection is reduced by taping the large white borders. There are still white lines of the aluminium wires.

Attempts to draw lines crudely resulted in the dropping of short circuit current from 1.25 A to 1.1 A. Limited the drawings to larger wires resulted in a reduction to only 1.2 A.

By using rulers and fine tipped marker pens, we can reduce the reflections even more.

These panels can power a car radio, even in a shade under the windshield.

These panels should have 0.08 A short circuit under shade. One is not sufficient to play the radio.

In the sun, 0.38 A under the windshield, 1.25 outside the windshield and pointed to the sun. When pointed to the sun, 0.48 A maximum when pointed to the sun under the windshield that is also tinted to block UV and Infrared light.

In another car that has no tint, the current was 0.6 A.

Using a thin layer of cupboard glass, the current reduces from 0.96 to 0.76 A.


These panels are .28 X .54 m in size but deduct .05 from them to get the solar panel area.


The panel below is a good dashboard solar panel because it is all black



This product is a good dashboard solar panel.

Our Solar Dash™ is a solar-powered battery charging system that keeps inactive trucks ready to roll by providing converted solar energy to the batteries. If you’ve ever had to leave a truck on your lot for extended periods of time, you know that batteries don’t stay charged forever.

The Solar Dash is placed on the dashboard of the vehicle and plugged into the 12 V port. The energy collected from the solar panel is converted and fed back into the vehicle’s batteries, fighting back against parasitic loads and maintaining a high state of charge in the batteries.

One of the best things about the Solar Dash is that it can be used over and over again. This means that once a truck fitted with the Solar Dash is ready to go back out into the field, you can simply transfer the system to another truck. No more dead batteries, no more jumpstarts, and no more time wasted. The possible savings mean that the Solar Bolt pays for itself.

The Solar Dash comes with:

  • 20 W Solar Panel
  • Conversion controller
  • 12 V power port adapter

Any of your vehicles that are inactive, especially during summer months, can have their batteries maintained by the Solar Dash and will be ready to work when needed.

Hit enter to search or ESC to close A Short Guide To Metric Nuts and Bolts Answers to the most Frequently Asked Questions Standard and Fine Pitch Threads How to identify nut and bolt strength grades How nut and bolt strength grades compare Maximum Tightening Torques Why specified torque is sometimes lower than the maximum Spanner Sizes Versus Bolt / Nut thread size Allen Key size versus Bolt / Nut thread size Correct Drill size for Tapping Metric threads in holes Introduction: Metric Nuts and Bolts This short guide is intended to give a very basic introduction to ISO metric nuts and bolts. It is intended for those working in plant and machinery maintenance to give enough information on to ensure that correct replacement parts are identified and used. Few parts are as critical in the assembly of modern machinery as the nuts and bolts which hold it all together and, at first sight, it seems that all metric bolts are basically the same. In fact, of course, nothing could be further from th...

CAN Bus Wiring Diagram, a Basics Tutorial

Image
https://tekeye.uk/automotive/can-bus-cable-wiring Index ↓ About ↓ CAN Bus Wiring Diagram, a Basics Tutorial The CAN bus is a common digital data network used in automotive, industrial, medical and scientific systems. The CAN bus is used for routing sensor data between pieces of equipment. The main advantages are high resilience to noise, reliability, low cost, simple wiring and ease of use. The disadvantages are that the data packet lengths are small, transmission rates are low and the message transmission cycle time can vary. This article covers the basics of CAN bus wiring, showing a simple CAN bus wiring diagram and how to wire up a CAN bus cable. It covers wiring for the common DB9 plug and socket often used with CAN bus test equipment. The DB9 is also known as 9-pin D-sub, DE-9 (its correct name), DB-9, serial connector, RS232 connector or null modem connector. The CAN bus is used in nearly every form...

Best Free CFD Tutorial: FreeCAD Openfoam CFD Workbench

Image
I find watching this video boring but the links are userful and the linked tutorial very helpful. Better than reading the instructiions in the FreeCAD Addon installation comments for CFDof. http://www.opensim.co.za/training.html   The tutorial that is useful in doing CFD for car is the one below: https://github.com/opensimsa/opensim/raw/master/Documentation/CFD/UAV2/CFD%20Tutorial%204%20-%20External%20Aerodynamics%20of%20a%20UAV.pdf   WINDOWS: ● https://www.freecadweb.org/wiki/Download ● Install CfdOF from Tools | Addon manager ● Go to Edit | Preferences | CFD to check and install dependencies   Of special note: I install the older version of Paraview as shown in the FreeCAD preferences. I downloaded cfmesh and HiSA from sourceforge. No need to look for binaries. It appears as though the master file  zipped file can be installed by FreeCAD.   cfMesh downloaded to C:\Users\othma\AppData\Local\Temp\tmpwg568v1r.zip Installing cfMesh...
