1.ROBOTIC LAWN MOWERS

A great looking lawn can be a lot of hard work. With a robotic lawn mower, the grass gets mowed automatically – around the clock without your supervision. Cuttings are small enough that you won’t need to rake the clippings, adding fertilization back to the soil.
2.Sion. A Solarcar for everyone.
https://www.sonomotors.com/
The Sion is an innovative electric car with integrated solar cells in the body, a range of 250km and a price of less than € 16,000. 30 free kilometers per day are possible with electricity generated by the sun. The stored energy can be used through bidirectional charging for all common electronic devices.
3.nipi – the portable solar generator & smart cooler

The idea of nipi came when we were on an extended camping trip. We wanted something that could keep our drinks cold, charge our phones, and our belongings safe. It had to be ultra mobile and look as good as all our other accessories.
4.Ellum Solar – Light Different
https://www.facebook.com/byfeltmark
The new Ellum Solar is an intuitive smart light, embedded with sensors that illuminate the dark when motion is detected. Meaningfully designed, the Ellum attaches magnetically and has a touch dimmer to manually adjust the brightness of the light, wherever you need it.
5.Lifepack: Solar Powered & Anti-Theft Backpack
http://lifepack.me/
The Solarbank can charge from empty to full overnight when you plug it into a wall socket via USB. The Solarbank has 2 USB outputs. 1A and 2A – Normal speed and high speed charging are both supported. When you use the Solarbank to charge your phone it will use some of the battery – then the Solar panel will keep the battery topped up.
A simple guide to controlling 12 volt LED strips from your Arduino using an N Channel Mosfet.
In my example I’m using PWM to fade the 12v LED strip, but you could just as easily turn the LED strip on and off instead of fading it. Also it doesn’t have to be an LED strip and it doesn’t have to be 12v!
If you’re going to drive a motor or a relay (or any inductive load) using this setup, you should add a diode across the positive and negative input of the motor/relay to avoid any back voltage.
I’ve over simplified things in terms of my description and the circuit, but it should be enough to get you up and running and to give you a basic understanding of how an N-Channel Mosfet works.
Pretty much any N Channel Mosfet will be fine, but ideally you want to go for an L series, because the gate can be reliably driven at lower voltages, such as the 5 volt from the Arduino.
If you’re curious, a MOSFET is a metal–oxide–semiconductor field-effect transistor. The benefit of a MOSFET over the traditional relay is that it can turn on and off extremely quickly, meaning it’s suitable for PWM, compared to the old coil relay which can’t turn on and off so quickly. Of course a modern solid state relay can compare against a mosfet or transistor.
