How to Make a Simple and Inexpensive Solar Oven - Making a DIY Solar Oven at Home. - A solar oven is a device which uses sunlight as its energy source. Solar cookers can also be used in outdoor cooking, especially in situations where minimal fuel consumption or fire risks are considered highly important. A solar oven can be built using simple household materials. These ovens are safe and easy to use.
All you have to do is to place your food in the oven, point towards the sun and, in a couple of hours, you'll have a hot meal. The oven can cook and warm many meals like rice, beans, soups, bread, cookies, cakes... and many more! This oven offers clean efficient energy without using any of the earth's resources or polluting the air. There are many plans and designs on how to build a solar oven.
In making a simple solar oven, we will be needing the following materials:
- cookie trays
- black paint
- aluminum sheets
- small volts
Steps on how to build a solar oven:
- In making a box, get pieces of 1/2 inch plywood, then frame the outside with 1x2's. Use metal cookie trays and screw them to the plywood on the inner side.
- Join the panels with screws, cut Styrofoam and glue them inside the frame.
- The outer layer of the box is made from 3/4 inch plywood. Paint the entire outside with flat black paint. Painting it black will assist the solar oven in retaining as much heat as possible. Using paint with a high gloss provides a sheen that can retain more heat.
- Connect the panels of the inner box together, and place it inside the outer box. Place styrofoam down the sides and bottoms of the two boxes. The inner box should be made from aluminum sheeting, glue it to a plywood and attach it to the inner box. Place a 2x2 block at the bottom of the box with Styrofoam placed underneath it.
- The panel for the sun collector should be made from aluminum sheets, glue it to a particle board and paint the other side.
- In making the solar cooker: Glue two 1/8 inch plywood together, with each plywood having square cuts out of them (the bottom piece had a smaller square cut out while the top one had a larger one). Provide a lip that the oven door could close into. Use small hinges to attach the door to the top edge of the cooker. Attach the top to the main box with screws.
- Attach the sun-collector panels to the solar oven using braces and bend at a 67 degree angle. Bolt the panels to the braces that were screwed into the main box. Attach the front panel with wing nuts, allowing for easy access to the door. Cut small panels to fit in the side gaps. Attach the main panels with the little piece of plastic as hinges and small bolts. This formed a complete sun collector around the oven.
Now your solar oven is ready to go! Take it to direct sunlight. You probably would want to install a thermometer to monitor the temperature inside the oven. That's it for the guidelines on how to build a solar oven.
