Project Overview

The Online Solar Challenge is open to international submissions, and provides the most accessible approach for any student team anywhere, to participate in a KidWind Challenge. Student teams in grades 4th-12th participate in age-level divisions to create a solar powered project on the theme Solar Home. A solar home is a type of structure that considers the environment, the inhabitants, and its functional and aesthetic design. We encourage teams to think creatively and even fantastically about their solar homes. The environment can range from outer space to the arctic, and the inhabitants can be anything from people to butterflies! You can check for confirmation that you submitted your project by looking at the View Projects section of the Online Solar Challenge page.

There are two Solar KidWind Challenge divisions: Solar Home and Solar Smart Home. Students in 4th-12th grade can participate in the Solar Home Division, and only students in 6th-12th grade can participate in the Solar Smart Home division. To upload a solar home, an adult coach is required to provide contact information. A coach can be a parent, educator, or mentor. A coach may supervise multiple teams. Once uploaded, the solar home project may be displayed within the Solar Challenge Gallery on the KidWind website.

Submissions will be judged by the KidWind team and winners will be selected on a quarterly basis. Winners receive prizes and are invited to participate in the World KidWind Challenge, a large and prestigious in-person event, hosted at a conference center in a different state every year.

Projects will be grouped for evaluation based on the following time frames:

  • Projects submitted by November 1st for Quarter 1
  • Projects submitted by February 1st for Quarter 2
  • Projects submitted by April 1st for Quarter 3
  • Projects submitted by August 1st for Quarter 4

Judging Rubric

  • 50% Resourcefulness, Creative Concept, Thoughtful Design, Skill and Aesthetics, World Connections
  • 50% Functionality, Research, Knowledge, Teamwork, Communication

If your team is chosen as a winner, a KidWind staff member will contact the coach. Winners selected from Quarters 1-3 (August 1st through April 1st) will be invited to a World KidWind Challenge in spring 2026.

How Do I Participate?

  • Download & read the detailed rules.
  • Fill out and upload the appropriate Solar Home requirements:
    • Solar Panel Schematic(s): In the solar panel schematic, include each solar powered circuit’s configuration (parallel/series), and a label to what the terminals connect to. Label each panel’s rated voltage and current, the length, width, and area of each solar panel, and each configurations voltage/current/wattage total. This Schematic is different from the wiring diagram because it only includes the solar panel arrangement, not the rest of the circuit. For example, if the team has up to three circuits that are powered by solar, they will need to provide three solar panel schematics. Find examples here.
    • Wiring Diagram(s): Each circuit requires a separate wiring diagram. Teams must provide a wiring diagram for no more than three circuits. Each wiring diagram must include a symbols key. The wiring diagram should have the symbols labeled for all the electrical parts of a circuit, and every emergency switch clearly labeled as such in the diagram. If using power storage, teams will label how the solar panels are charging the power storage and how the storage is powering the loads on the device. Solar Home Elementary 4th-5th Division can create a hand drawn wiring diagram. Find examples here.
    • Programming codeFor Solar Smart Home Division only. Provide the programming code used to program the microcontroller.
    • Materials ListThe material list is a document for teams to record all materials used in the solar home, how the materials were used, if the materials are recycled, found, or new, and the costs of materials. If the material is a 3D printed part, teams must explain if the file was found, modified, or created. Budget should identify 3D printed parts as new material cost. Material cost = filament price/filament weight  x  model weight. See Materials in Requirements for more information.

Please note: The more data you share in the project submission form, the better our judges will be able to evaluate and score your Solar Home. Teams that submit details in most or all of the submission form fields often score higher.

Standards Addressed

The Solar Challenge is a STEAM activity and connects to and is judged by STEAM standards.

McDuck Manor
Solar Smart Home

Project Overview

The McDuck Manor powers the urban metropolis known as Duckburg, fueling every need and desire of the citizens. Since Mr. McDuck owns the panels, the amount of money located in his bin is constantly growing without him lifting a finger. With everyone relying on his clean, reliable power.

The ViBRAINiums
Solar Smart Home

Project Overview

Our group is called the ViBRAINiums and we are making a solar-powered home themed and based on the hit MCU cinematic movies, Black Panther and Black Panther: Wakanda Forever. Vibranium is a powerful, high-energy conducting ore that will be represented by the constantly-scanning solar panel for the greatest amount of light energy received to power our solar home.

Sentinel
Solar Smart Home

Project Overview

The Sentinel-01 is a fully custom, 3D-printed solar house designed and built by Energy Optix, a five-person team from Lanier High School in Sugar Hill, Georgia. It features a dual-axis solar tracking system controlled by a BBC micro:bit, which reads voltage from two solar panels in series to scan and find the optimal light-facing position. Compact enough to fit within a one-foot cube, the Sentinel-01 demonstrates how intelligent, active solar tracking can maximize renewable energy harvest in a small, self-sufficient home.

Solara Drift
Solar Smart Home

Project Overview

This project has a cyberpunk theme, containing motorized solar panels to ensure maximum energy efficiency. Voltage input from the solar panels allow it to automatically position itself using servos to face the strongest source of light to ensure the best utilization of the sun's energy. This project has a futuristic look and feel while creating an efficient source of renewable energy.

Sun-eaters

Hallford's Heroes
Solar Smart Home

Project Overview

Deep in the forest, the Sun-eaters' abandoned power plant brings sanctuary to plants and animal life with structure, stability, and power produced from its Solar-Flower. The Sun-eaters’ abandoned power plant’s original purpose in the world was to provide power to people, but now that it’s rundown and abandoned by its creators, it uses its power of solar energy to give the plants and animals it hosts the security they need to survive. The design of the power plant was made to fit in with its surroundings and with the moss and scattered rocks from years of abandonment it has become one with its forested surroundings. The loss of habitats and deforestation is a real problem for animals and plants alike.

Project Overview

We were tasked with building a structure that consisted of servos and solar panels. Our goal was to combine engineering and computer science concepts to create a design that maximized efficiency from the solar panels we were given. The main challenge of the project was making a design that allowed the solar panels to function while the sun changed locations.

The Breezy Bee, Solar Home for Bees
Solar Home

Project Overview

The solar home is called the Breezy Bee, With honeybees in almost a free fall decline we wanted to find a way to bolster hive production and provide a helpful hand to level off and eventually invert the decline. We built the Breezy Bee which vents our hive using a servo motor. We also built the Bee Booster package which waters gardens and provides a clean water source for bees.
