What is a Solar-Powered Hot Plate

A solar-powered hot plate is versatile, portable, and convenient kitchen equipment for cooking or heating food with solar energy. It is a device that converts the sun's rays into heat energy, which can be used for cooking purposes. It can either work as a stand-alone unit or as part of a solar cooking system.

If you are camping outdoors or hosting an outdoor backyard party with no nearby electrical outlets, you would need a solar-powered hot plate that works using sunlight. A solar hot plate can cook food even if there is no fuel or electricity available from the utility grid.

A solar hot plate can be perfect for picnics and other outdoor adventures where traditional cooking methods sound impractical. You can also use the hot plate in regions with inconsistent power supply or if there is a power outage in your area. It can be a valuable tool for disaster preparedness or when you want to minimize the reliance on fossil fuels.

How Does a Solar-Powered Hot Plate Work

A solar-powered hot plate is a cooking device that uses sunlight to heat water or cook food. Most solar-powered hot plates use a flat plate collector or a solar panel-like device consisting of a dark-colored heat-absorbing surface, a transparent cover, and insulation. The sunlight hits the collector, where the dark surface absorbs the solar radiation and converts it to heat energy.

The solar cookers similarly convert light energy into concentrated heat energy, which is used to cook food. Sunlight-to-heat conversion occurs when photons of light waves interact with substance molecules. Here's the step-by-step working process of a solar-powered hot plate:

Step 1: Concentrating Sunlight Into Cooking Space

The mirror surface with high specular reflection works by concentrating and channeling the sun's light into a small cooking space. Ideally, solar cookers are designed to achieve temperatures of around 65°C (149°F) — 400°C (752°F) for cooking food. Several orders of magnitude concentrate the sunlight to produce a high magnitude suitable for melting salt and metal.

Step 2: Converting Light to Heat Energy

Concentrated sunlight is then focused onto the hot plate (or receiver). The interaction between the receiver material and light energy converts light into heat through the conduction process. Solar-powered hot plates made with matte black color can maximize absorption.

Step 3: Trapping Heat Energy

Isolating the air inside the solar cooker or hot plate from the outside air reduces convection. Consider using a glass lid to maximize light absorption and decrease convection energy loss. This will help you cook food faster and ensure you can enjoy uninterrupted outdoor parties.

How Many Watts to Power a Hot Plate

On average, a solar hot plate consumes 200W — 1500W of electricity per hour. Small solar hot plates draw around 200W — 500W of electricity per hour, whereas the electric hot plate requires 750W — 1500W of electricity per hour. Many people rely on solar hot plates for meal preparation outdoors. These devices vary from single burners to double burners and induction models.

Before choosing the right power station, one must understand three basic electrical terms: amps, watts, and volts.

Amps: Also called amperage, it measures the amount of electricity that runs through the electrical circuit. Amps represent the number of electrons moving through the electrical wire or the rate at which the current flows.

Watts: Wattage measures the amount of power that an electrical appliance, such as a hot plate, uses. The higher the wattage, the more power the appliance requires.

Volts: Voltage is the electric pressure that pushes electricity through the electrical circuit. The higher the voltage, the more electricity will flow to an electronic device such as a hot plate or induction cooker.

Let's say an average hot plate draws nearly 1200 watts of electricity per hour. If you are using the hot plate for one hour each day, it will consume 1200Wh per day or 36,000Wh per month. Here's a table revealing the wattage consumption, usage time, and power needed for the solar-powered hot plates:

How to Make a Solar-Powered Hot Plate

Creating a truly functional solar-powered hot plate requires more complicated electrical components and involves a complex process. However, you can make a DIY solar oven that uses solar energy to cook food, similar to solar hot plates. You can recycle the cardboard boxes to create a simple pizza box solar oven.

Here are the items you would need to make a solar-powered hot plate or solar oven:

• Cardboard pizza box
• Box knife or scissors
• Clear tape
• Plastic wrap
• Aluminum foil
• Newspaper
• Ruler or wooden spoon
• Black construction paper
• Thermometer

Once you've all the items ready, here's a step-by-step process to make a DIY solar cooker with a pizza box and household items:

Step 1: Cut the Pizza Box

With the help of a box knife or sharp scissors, cut the flap in the lid of the pizza box. Cut the three sides of the pizza box, leaving about an inch between the sides of the lid's flap and the edges. Carefully fold the flap out so it stands up when you close the box lid.

Step 2: Use Aluminium Foil to Cover the Interior

Use aluminum foil to cover the inner side of the flap and reflect sunlight. Tightly wrap the foil around the flap and tape it to the back or on the outer side of the flap.

Step 3: Create an Airtight Window Using Plastic

With the help of clear plastic wrap, create an airtight window so sunlight can enter the pizza box. To do this, open the box and tap a double layer of plastic wrapping over the box opening.

Make sure to leave about an inch of plastic overlap around both sides and tape each side down to seal the air. If you are using a plastic bag, cut a square to cover the opening and tape one layer over the opening.

Step 4: Line the Bottom With Paper

Use black construction paper to line the bottom of the box because black can absorb all known wavelengths of light and convert them into thermal energy or heat. Remember, you will cook food on this black surface.

Step 5: Insulate the Solar Oven

Roll up the newspaper sheets and place them on the bottom of the box to insulate the solar oven so it can hold more heat. Carefully tape them down to form a border around the cooking area. Make sure the newspaper rolls are such that the lid can still close, but there's a seal inside the box so air cannot escape.

Step 6: Set up the Solar Oven

The best time to set up the solar-powered oven or hot plate is when the sun is high overhead from 11 a.m. to 3 p.m. All you need to do is set up the solar oven in a sunny spot and adjust the flap so that most sunlight reflects off the aluminum foil and the plastic-covered window. You can use a ruler to prop the flap at the right angle.

Solar Powered Hot Plate FAQs

What size generator do I need for my hot plate?

The size of a solar-powered generator required for a hot plate will be influenced by the wattage consumption of the hot plate and how long you want to use it. For instance, suppose you are camping outdoors and want to charge an electric solar hot plate (750W) with the help of the Jackery Solar Generator 1000 Plus. In this case, the running time can be calculated using the below formula:

Running Time = Battery Capacity in Wh × 0.85 ÷ Operating Wattage of the Appliance = 1264Wh × 0.85 ÷ 750W = 1.4H

Note: We have multiplied the battery capacity by 0.85 because charging the appliance will cause some power loss.
