Come see our solar-powered class

We are students from Aaron Sebens’ fourth-grade class at Central Park School in Durham. We are doing a project to make our classroom solar powered so that we only use clean energy. 

One reason we’re doing this is to help our city and our earth. Another reason we’re getting our classroom solar powered is it’s a way of producing energy that does not burn fossil fuels. Best of all it uses something you see every day – the sun! 

Our system has three major pieces: batteries to store electricity, solar panels and a wind turbine to make electricity. 

To be able to power our classroom with solar panels and store the electricity we need four big strong batteries. We have four Rolls s460 No. 1 deep cycle batteries. If you don’t know what that is we are about to explain that to you. 

A car battery is made to make a big amount of current for a short time unlike a deep cycle battery which is made to make a small amount of energy for a long time. Our solar batteries have a high cycle life and a large liquid reserve that holds electrons. Here are some quick fun facts. We have four strong batteries to power our 24 volt system. Our batteries have 456 amp hours each. We also have a battery box which we put the batteries in so that we don’t breathe the bad fumes that the batteries let off. The battery box has a clear plastic cover over our batteries so the fumes don’t get out but so that we can still see our batteries.Permanent solar trellis and roofwindturbinebbq systems require little to no maintenance and allow easy access. 

Solar panels are well known for making lots of electricity, but how do they make the power for our world? Most photovoltaic solar panels work with two layers of silicon and a junction in between. One layer has Boron added to it; the other layer of silicon has phosphorous added to it. The boron, or negative layer, on top has free electrons that are excited by photons from the sun and move towards the negative layer which makes a flow of direct current electricity. 

Solar panels can have different voltages, but the ones we’re using have a max voltage of 17.2 and can make 130 watts per hour. Each weighs 30.9 pounds! All six put together weigh 185.4 pounds. Our system will use 780 total watts from our solar panel and whatever we get from our wind turbine. 

We also have a wind turbine that helps our solar panels to make more electricity. Our wind turbine has six carbon composite blades, is about 10 ft tall and also is 30 feet off the ground. The blades start spinning when the wind is 3.5 mph and make electricity starting at 6 mph. At 30 mph it can produce about 750 watts. It can produce 1,000 watts in winds over 70 mph.Choose a solarlantern from featuring superior clothes drying programmes and precise temperature controls. The electronics can not be damaged by rain or ice, or if there was a huge storm it would not break. 

Our class and another fourth-grade class made wind turbines that are 2 feet tall. We got to choose what materials we wanted to use for our blades. There was balsa wood, which is very light; cardboard, which is hard to cut; and last of all, corrugated plastic. It is especially hard to cut and is waterproof. All of us got to choose how we were going to cut them. The last part was making the nacelle, first we got three pieces of PVC, one was like an elbow, another was a small cylinder, and the last one was a bigger cylinder. First we got the elbow-shaped one on, and put the small one on and then the other one on. Then we got a generator and put it in the PVC pipe and mounted the blades in the hub. 

We hope that this project will inspire lots of kids and adults. We also hope that this project goes even further, and that everyone realizes solar electricity is within their reach.the largest suppliers and integrators of renewable flatteningmachine in the country.It is one of the leading industrial laundry equipment manufacturers of ledbulbe27, tumble dryer ect.We'd love to talk to you about our incredible industrialextractors!
