How to Cook with Solar Power Using a Solar Oven

Have you ever thought about harnessing the power of the sun to cook your food? It might sound like something out of science fiction, but solar oven cooking is a very real and practical way to prepare delicious and healthy meals.

In this blog post, we’ll explore the wonderful world of solar cooking, and how you can cook with solar power teaching you everything you need to know to get started.

What is a Solar Oven?

A solar oven is a specially designed box that uses sunlight to trap heat and cook food. It’s essentially a miniature greenhouse that concentrates the sun’s rays to reach high temperatures, similar to a conventional oven.

These ovens come in various designs, ranging from simple cardboard box creations to commercially available, pre-built options.

How Solar Ovens Work

A solar oven is essentially a box designed to capture and trap the sun’s heat. It typically consists of:

How Solar Ovens Work

An insulated box: 

This box helps retain the heat generated inside the oven. Common materials used for insulation include cardboard, foam, or reflective materials.

Transparent cover: 

This allows sunlight to enter the oven while trapping the heat inside. Glass or clear plastic are commonly used materials.

Reflective surface: 

This surface, often made of aluminum foil or reflective film, helps concentrate the sun’s rays inside the oven, increasing its cooking temperature.

Cooking pot: 

This is where you place your food to be cooked. Black pots are ideal as they absorb heat more efficiently.

When sunlight enters the solar oven through the transparent cover, it gets trapped inside due to the insulation. The reflective surface further intensifies the heat, creating an environment hot enough to cook food.

Types of Solar Ovens

There are two main types of solar ovens:

  • Box-type solar ovens: These are the most common type and come in various sizes and designs. They are typically portable and easy to use.
  • Parabolic solar ovens: These ovens use a curved, reflective surface to concentrate sunlight onto a single point, where the cooking pot is placed. They can reach higher temperatures but are generally less portable than box-type ovens.

How to Use a Solar Oven

Using a solar oven is surprisingly simple. Here’s a basic guide:

  1. Choose a sunny location: Find a spot with direct sunlight for most of the day. Make sure no shadows are falling on the oven.
  2. Prepare your food: Many recipes work well in a solar oven, similar to those cooked in a conventional oven. However, it’s important to pre-cook meats and choose recipes that cook well at lower temperatures for extended periods.
  3. Place your food in a dark, oven-safe pot: Black pots are best for absorbing heat. Cover the pot with a tight-fitting lid to trap heat and moisture.
  4. Position the oven: Angle the oven towards the sun to maximize sunlight capture. You might need to adjust the angle throughout the day as the sun moves.
  5. Let your food cook: Cooking times in a solar oven can be longer than in a conventional oven, so be patient. Check on your food periodically and stir or rotate it if necessary.
  6. Enjoy your solar-cooked meal!

Tips for Successful Solar Cooking

Here are some additional tips to help you cook delicious meals using your solar oven:

  • Use pre-cooked meats: As solar ovens cook at lower temperatures, pre-cooking meats is crucial to ensure they reach a safe internal temperature.
  • Choose dark-colored pots: Dark colors absorb heat more efficiently, leading to faster cooking times.
  • Use clear glass lids: Clear lids allow sunlight to penetrate the pot while still trapping heat and moisture.
  • Insulate your pot: Wrapping your pot in a towel or newspaper can further help retain heat.
  • Start early: The sooner you start cooking in the day, the more time your food has to cook before the sun sets.

Why Cook with Solar Power?

There are several compelling reasons to embrace solar oven cooking:

  • Sustainable: Solar power is a clean and renewable energy source, so using a solar oven helps reduce your reliance on fossil fuels and your environmental impact.
  • Cost-effective: Once you’ve built or purchased your solar oven, the “fuel” is completely free – sunshine! This can save you money on your energy bills in the long run.
  • Easy to use: Solar oven cooking is surprisingly straightforward. Once you understand the basic principles, anyone can whip up delicious meals using the sun’s power.
  • Portable: Many solar ovens are compact and lightweight, making them ideal for camping, picnics, or even emergencies where traditional cooking methods might not be available.

Getting Started with Solar Cooking

Now that you’re excited about the potential of solar cooking, let’s dive into the practical steps:

Getting Started with Solar Cooking

1. Choosing a Solar Oven

There are two main options – building your own or purchasing a pre-made one. Building a solar oven can be a fun and educational project, but it requires some basic DIY skills. If you prefer a more convenient option, several companies offer high-quality, ready-to-use solar ovens.

2. Selecting the Right Recipe

Solar ovens are best suited for dishes that cook slowly and at lower temperatures, such as stews, casseroles, breads, and even desserts. While you can’t replicate the high heat of a conventional oven for things like searing or broiling, the possibilities for solar cooking are vast and delicious.

3. Preparing Your Food

Similar to conventional oven cooking, preheat your solar oven for about 15-30 minutes before adding your prepared food. Use dark-colored pots and pans, as they absorb heat more efficiently. Tightly cover your food to trap the heat and prevent evaporation.

4. Cooking with the Sun

Position your solar oven in direct sunlight, preferably facing south to maximize sun exposure. Throughout the day, you might need to adjust the oven’s position to keep it aligned with the sun’s movement.

Be patient, as solar cooking takes longer than traditional methods. Depending on the recipe and weather conditions, cooking times can vary, so check on your food periodically.

5. Enjoy Your Solar-Cooked Meal

Once your food is cooked to your liking, carefully remove it from the oven using oven mitts. Savor the deliciousness of your solar-powered meal, knowing you’ve cooked sustainably and enjoyed the sun’s natural bounty.

Recipes for Your Solar Oven

Now that you know the basics of using a solar oven, you might be wondering what you can cook in it. The possibilities are endless! Here are some recipe ideas to get you started:

  • Stews and soups: These are perfect for solar cooking as they cook well at lower temperatures for extended periods.
  • Casseroles: Similar to stews, casseroles are another great option for slow cooking in a solar oven.
  • Baked vegetables: Roasting vegetables in a solar oven brings out their natural sweetness and creates a delicious caramelized flavor.
  • Bread: Baking bread in a solar oven takes practice, but it’s a rewarding experience with delicious results.
  • Desserts: From brownies to cobblers, you can even experiment with baking some simple desserts in your solar oven.


Solar oven cooking offers a unique and rewarding way to prepare delicious meals while embracing sustainability. It’s a simple yet effective technology that empowers you to harness the sun’s power and contribute to a greener future.

So, why not give it a try? You might be surprised at how easy and enjoyable it is to cook in the sunshine!
