Solar Panel Grid Connect
I have an idea and I want to know if it can work. Thx engineers.?
An airport that runs only on solar power. Every roof has solar panels to power it during the day and it has a fleet of unmanned aerial vehicles (UAV) that are solar powered and have energy collectors. During the day they fly around in circles and collect energy all day long and then at night they set down and connect to a grid to power the airport. A completely green airport. So besides costs are there any reasons why this wouldn’t work and of course they would use normal electricity as a backup or even dual mode so that part of an airport uses electricity(computers/ half the lights) and the other parts like (escalators and the other lights )would use solar power.
Well, there are 3 things you need here: How much energy an average airport uses, how much surface area it has, and how much energy you get from sunlight per surface area. Then assuming you have enough space on the airport to provide for its energy needs, you can look up the average price for solar cells and how much it would cost to cover it. Then you can see how many years you expect those cells to last (20 years), and calculate the costs of that vs. buying electricity from the grid for 20 years.
The bottom line:
1) It’s a nice sentiment, but yes, the main problem is that it would still be too expensive.
2) I can tell you right now that the UAV’s will spend all their energy flying around and will not contribute to the charge of the airport. Remember the amount of energy you get from solar is dependent on the amount of surface area of direct sunlight you are covering. Assuming you don’t have football court sized UAVs, they will be useless for solar harvesting.
