Mini Solar Book Torch/Charger
Build a portable solar-powered torch and charger that can provide up to 30 hours of LED lighting and USB charging capabilities. This device is perfect for powering small gadgets like phones or GPS devices. The project requires a solar panel, a rechargeable battery, and a USB port. It’s compact enough to carry in a backpack or pocket.
Solar Food Dryer
Preserve excess seasonal produce by building a solar food dryer. This project involves creating a box with a glass or plastic lid to capture sunlight and heat. Place racks inside the box to hold the produce. This method maintains nutrients better than canning or freezing. Ideal for drying fruits and vegetables for long-term storage.
DIY Laminated Solar Panels
Combine solar cells in series or parallel to achieve a usable voltage, such as 5V. This project requires soldering and a basic understanding of electrical circuits. By laminating the solar cells, you can create a durable and weather-resistant panel. This setup can power small devices or be used as part of a larger solar array.
Window Mounted Hot Air Furnace
Install a temporary solar heater outside windows using a modified flyscreen. This project requires minimal materials and no permanent ductwork. The flyscreen acts as a heat collector, and the warm air is directed into the room through a vent. This is a great way to supplement your heating needs during colder months.
Solar Shrub
Create an aesthetically pleasing USB charger that resembles a potted plant. This project involves building a solar-powered USB charger that can charge iPhones, iPods, and other USB devices. The charger is designed to look like a potted plant, making it a functional and decorative addition to any room. It’s perfect for charging devices while you’re working or relaxing.
Parabolic Hot Water Heater
Use a mirrored parabolic dish to focus sunlight on copper tubing, generating near-boiling water on demand. This project requires careful construction to ensure the parabolic shape is accurate. The heated water can be used for cleaning or other purposes. This setup is ideal for those who need hot water in remote locations or off-grid settings.
Portable Solar Outlet
Power 80W devices for 3+ hours or run electric drills with this robust solar panel setup. This project involves building a portable solar panel that can be easily transported and set up. It’s perfect for powering tools or devices in outdoor settings where access to electricity is limited. The setup includes a solar panel, battery, and inverter.
Solar Power Altoid Tin
Repurpose solar path lights into a compact charger. This project involves modifying a MintyBoost kit to use a solar panel and lithium-ion battery for charging devices like iPhones. The components are housed in an Altoids tin with a mono audio connector. This project is ideal for those who need a compact and portable solar charger.
Sun Laser Wood Engraving
Use a magnifying glass, aluminum foil, and sunglasses or a razor blade for precision. This project requires careful supervision to prevent accidents. The magnifying glass focuses sunlight onto the wood, and the aluminum foil directs the light to create intricate designs. This method is perfect for engraving small objects or creating detailed artwork.
Solar Water Heater
Build a low-cost system using a black container and insulation to heat water for cleaning or other uses. This project involves creating a box with a black container inside and insulation around it. The box is covered with a clear plastic lid to capture sunlight. This setup is ideal for those who need hot water in remote locations or off-grid settings.
Soda Can Fire Starter
Polish a soda can’s bottom with chocolate to intensify sunlight reflections, creating a focused beam for starting fires. This project requires careful polishing to achieve the right level of reflectivity. The polished can acts as a magnifying glass, focusing sunlight onto kindling to start a fire. This method is perfect for those who need a reliable way to start fires in outdoor settings.
Solar-Powered Lawnmower
Retrofit a battery-powered mower to use solar panels for charging, reducing reliance on electricity. This project involves installing solar panels on the roof or a nearby structure to charge the mower’s battery. This setup is ideal for those who want to reduce their reliance on grid electricity and use renewable energy sources.
Solar Potential Estimator
Use tools like RoofRay to analyze your home’s roof and location data to estimate solar energy generation potential. This project involves using online tools to determine the best location for solar panels based on your roof’s orientation and the amount of sunlight it receives. This information can help you plan your solar energy system and maximize its efficiency.
Solar Wi-Fi Extender
Assemble a solar-powered Wi-Fi router with a battery, solar panel, and antenna to extend internet access outdoors. This project involves building a solar-powered Wi-Fi router that can be placed in remote locations. The setup includes a solar panel, battery, and antenna to provide internet access in areas where traditional Wi-Fi signals are weak.
Cardboard Solar Oven
Construct an oven using cardboard, aluminum foil, and plastic to cook food using sunlight. This project involves building a box with a glass or plastic lid to capture sunlight and heat. The box is lined with aluminum foil to reflect sunlight onto the food. This setup is ideal for cooking food using sunlight and reducing reliance on traditional cooking methods.
Budget Greenhouse
Build a $50 greenhouse using PVC pipes, plastic sheeting, and a window for year-round plant growth. This project involves creating a simple greenhouse using PVC pipes and plastic sheeting. The greenhouse can be placed in a sunny location and used to grow plants year-round. This setup is ideal for those who want to grow plants in a controlled environment.
Solar Phone Charger
Modify a MintyBoost kit to use a solar panel and lithium-ion battery for charging devices like iPhones. This project involves building a compact and portable solar charger that can be used to charge devices like iPhones. The setup includes a solar panel, battery, and USB port. This project is ideal for those who need a reliable way to charge their devices while on the go.
Sun Jar Lights
Create DIY solar-powered garden lights using jars, solar panels, and LEDs for low-cost outdoor illumination. This project involves building a simple and inexpensive solar-powered garden light using jars, solar panels, and LEDs. The lights can be placed around patios or walkways to provide ambient lighting. This setup is ideal for those who want to add lighting to their outdoor spaces without the need for wiring or electricity.
