Components Required: Tiny jars, solar-powered lamps, cans of frosting spray of chosen colors, pliers, a screwdriver, and tape. Starting a Fire with Chocolate and a Can (Easy) Applications: During a hot summer day, if you want free air that’s powered by the sun, this project will come in handy. Besides just you, if you decide to scale the project, you can cool down an entire room with enough solar power. Components Required: A solar charger, a Bluetooth speaker, a phone charger, a phone, and the sun. Solar-Powered Car (Easy)

Applications: This method is inexpensive and straightforward if you’re trying to turn an ordinary bath into a hot tub party or even if you’re trying to turn the heat up in your swimming pool. Even on colder days, you can heat your hot tub with the sun to be temperature-ready for yourself. With one bottle filled with dirty water, purified water will be evaporated and collected in the second bottle, empty, as the sun shines down on the bottles. In just a few minutes, you’ll start seeing water droplets! The solar oven focuses the sun’s rays and traps them within a glass box, almost like how a traditional oven heats the food.The battery needs sun to fully charge, and your Sun Jar may need charging before its first use. Leave outside or in a sunny window in DIRECT SUNLIGHT for several hours. In overcast conditions we recommend charging for a few days. Components Required: Many mirrors, a glass dome, a buildable chimney (if building another chimney for solar power), and time. Solar Refrigerator (Medium) From there, you can turn on the water and shower with the warmed-up water—the only downside is that the water’s amount is limited to how large the shed is and how long it’s been in the sun. The Sun Jar uses solar panels to charge through the day, it then uses the stored energy to glow during the night. A light sensor allows the jar to illuminate once in darkness, helping to create magical lighting, be it outside in a garden or as a nightlight for a child. The frosted glass of the jar helps to hide all the internal components and helps to diffuse the light produced to create a more natural lighting effect. This allows the jar to be an enchanting device that appears to truly capture the sunlight and release it during the night. The Sun Jar is fully waterproof and so can be used outdoors in all weathers to provide an enchanting lighting effect. Some projects are easier than others, and some require more complex thinking to accomplish (which is why we put in a difficulty meter), but in the end, every project is educational and valuable—so, let’s get started! Solar DIY Projects [Easy to Hard] Sun Jar Solar Light (Easy)

FCC (USA Only) Complies with part 15 of FCC rules. Safe to use without interfering with other electrical devices. All you have to do is calculate the square footage of your roof and divide the number by 15 (the square footage of an average solar panel)—that is how many solar panels you’ll need. Applications: If you need an energy-saving method to heat water to shower with, this lengthy but simple DIY build will impress you and your neighbors. If you do not want your Sun Jar to light up when it gets dark, lift the metal lever to release the lid and set the switch to "Charge" mode. This conserves battery life whilst continuing to charge it. (The Sun Jar also charges in "Auto" mode) Leave the solar lights on the Mason jars outside in the sun to charge for a day (four - 12 hours) before you glue them together. Occasionally a solar light is faulty right out of the box and doesn't work well or at all. If a light doesn't work, it's better to find out before you glue it to a Mason jar and can't return it.Brief Overall: The Sun Jar Solar Light is a way to spice up your garden decor—it’s a jar that “captures” sunlight into a pot and lights up an area with a colorful glow of your choice for the night! Applications: The best use for this build is for refrigerating food during a hot, summer day. This doesn’t apply to items that need to stay below a specific temperature, like meat or frozen foods, but it’ll make sure that your drinks stay cool during the day. Brief Overall: Even though this project requires a lot of work and parts, it’s one of the most beneficial DIY projects out there. Components Required: A solar-powered fan, an insulated box, aluminum foil, scissors, a blade or a saw, glue, tape, and standard hardware tools. Solar-Powered Water Still (Medium)

Applications: By allowing a certain amount of light in, students can measure how far the solar car travels over time to calculate how much power is being inputted into the solar panel or even how much energy is being lost by being translated into AC power. I’d say it is, but it depends upon how much gut you want pulled into the jar? The more gut goes in, the less pressure there is on your balls as the gut is fatty tissue and more easily expands.With this point, you can light the chocolate bar’s wrapper on fire within seconds in the right conditions. The Sun Jar is an interesting solar-powered device that can be used as a lamp or lighting feature both indoors and outdoors. The jar charges through the day to illuminate once in darkness, the frosted glass defusing the light giving it a true sunlight appearance. Although we’d love to think that the sun jar is simply a jam jar with a mini sun in it, the reality is slightly more technical! When the jar is placed in sunlight (for the best result put it in direct sunlight), the solar cell inside the jar creates an electrical current that charges the rechargeable battery. This energy then powers the LED lamp inside the jar at night-time. Applications: If you’re all out of matches during a camping trip, chocolate and a soda can are likely to be found. Even without the chocolate, you can use a soda can to impress your friends and family by starting a campfire with a standard, everyday household item. Components Required: A tub, an AC solar power inverter, solar panels, a solar battery, a charge controller, an AC power inlet, LED floodlights, and standard tools.
