I have constructed my first DIY solar panel for Solar RV heating in less than two hours.
Maybe you are wondering why I would want to build a 12 volt RV heater?
It might be a good idea to start with small RV DIY projects first.
Especially if you're interested in building a portable 12volt RV heater or want to start with a large homemade solar project, but you have doubts regarding DIY solar panels efficiency.
You can quickly build a miniature prototype. With this down-scaled version of the solar heating unit, you will be able to test the "proof of concept" and see how the system will perform in real conditions.
Besides demonstration purposes, a mini solar panel can be used to preheat the cabin of your RV, car, or boat. You only need to bring the solar panel inside the vehicle, put it onto a windshield. Have in mind to park the RV in the correct spot and direction, with the windshield facing the side where the sun will come out in the morning. And there you have it, a simple but extremely efficient solar heating device for car, RV, truck or boat cabin!
Solar RV Heating DIY Project: Parts specification
- 15 beer cans, preferably larger (o.5 liter)
- Few cardboard boxes, preferably with thicker sides
- Piece of glass, Lexan or plexiglass
- 12 Volt Cooler fan recovered from an old PC power supply
- 12 Volt DC plug to supply the fan (cooler), or
- 12 Volt PV solar panel if you're going to preheat your car with automatic on/off function
Here is some cool picture of this unique, cheap, and simple sun collector for solar RV heating. All material and parts are actually re-used junk. Basically, something that would most probably end up in the trash if there wasn't the opportunity to use all that to build our Do-It-Yourself solar panels.
It is an extraordinary feeling when you find out that your mini solar panel works! As you can see from the picture, this small solar thermal panel heated the air to 88ºC / 190ºF after barely half an hour under the sun! You can only imagine what amount of heating power can be produced with regular-sized solar thermal panels sitting in the sun all day.
People think that you have to live in southern or tropical areas to be able to use solar energy and build DIY RV solar panels.
In fact, solar thermal panels work very well in southern parts and on an overcast day.
Usually, it is sufficient to have some sunlight or at least diffuse light.
Still, off course, more direct sunlight converts into more energy that we can harvest for our solar RV DIY project...
