Renewable energy systems:
Solar Energy Management System Project
This project distributes the power which is produced from renewable energy sources. Once the capacity & efficiency of the solar panel is increased, then designing the solar grid is possible to solve the electricity problems. This grid can distribute the electricity in the areas of urban & rural so that electrical problems can be solved. However, to maintain and store the energy of this system, it requires a huge inverter to store solar energy which is variable largely. So to overcome this issue, solar grids are designed and connected in parallel with the current grids by the management.
Solar Energy Project for Home
The solar energy project for home is designed to generate AC power to a home for providing the required power to operate appliances, gadgets, lighting systems, refrigerators, computers, mixers, ACs, fans, etc. The essential components used in this system are the solar panel, battery, inverter, and solar power system.
Whenever the energy from the sun falls on the solar panel, then the energy can be absorbed through the photovoltaic cells. The energy conversion from solar to electrical in the solar cells can be done with the help of silicon semiconductors using the effect of PV. The converted energy is in the form of DC so that it can directly charge the battery. The battery includes a DC that is transmitted to an inverter to convert it into AC. Now the AC power is transmitted to the mains to provide the power to all the appliances in the home.
Water Purification using Solar Energy
There are different water sources available for drinking water in the world, but the available water in many areas is not pure, brackish, and saline. In coastal areas like Gujarat, and Kutch, the major problem is Salinity. So for water purification, there are different methods that are available in the market namely, sand filters, removal of fluoride, overturn osmosis plants, etc.
To overcome this problem, here is a system namely a solar energy-based water purification system which works on the principle of reverse osmosis. This project uses renewable energy like solar energy. The main reason to use this energy is cheap, abundant, pollution-less, etc.
In the power failure case, the water purifier system continuously works by using solar energy. This project uses 8051 microcontrollers to stop the overflow of water and this water purifier is applicable in the areas of rural and remote wherever the availability of electricity is not there and natural disaster places. By using this project, the salt content within the water can be reduced.
Solar Insect Robot
A solar-based insect robot is one kind of lightweight machine. This insect flies without using a power source. This robot has four wings that shake 170 times per second. The width of the insect wing is 3.5cms and the height is 6.5cms. This robot was invented at Harvard University by Noah Jaffer is & his colleagues.
The wings of solar insect robots are controlled through two plates. Once the current flows throughout them, then it bonds. The power used by this insect is six small solar cells where each cell weight 10 milligrams. These cells are arranged on the wings of the robot
Once the robot is exposed to light, then the wings will start flapping. Generally, this robot flies for half of a second approximately before it goes away from the light. In the future, this project can be developed to fly the robot in the sunlight & integrate sensing mechanisms.
IoT-based Monitoring System using Solar Energy
Power plants based on solar energy must be monitored to get the optimum output power. This system helps in recovering efficient output power while checking the faulty solar panels. This retrieves efficient output power from power plants while monitoring for faulty solar panels, and dust on panels & connections because these issues will affect the performance of solar. So this proposed system allows the monitoring system based on solar power using the internet from anywhere. This project monitors the panel constantly and transmits the output power to the IoT system using the internet.
This project uses IOT Gecko for transmitting the parameters of solar power through the internet to the IOT Gecko server. Now with the help of an effective GUI, it displays the parameters of the solar power & gives an alert to the user once the output drops under the specified limits. So that monitoring of solar plants is very easy remotely.
Dual Management System of Solar Panel Using IoT
The proposed system namely a dual management system for solar panels based on IoT performs two tasks solar panel theft prevention and an indication of maintenance through sensors & LinkIt ONE. Using this project will reduce the frequent visits & cost of transportation and increase solar panel usage as well as efficiency.
Theft prevention can be achieved by using GPS as well as LinkIt ONE Board of GPRS using an accelerometer. If the solar panel turns then there is an activity that will be occurred so that there is a change within the value of the axis in the accelerometer. This will be detected through LinkIt ONE. So that the data can be processed and the GPS location of the panel can be tracked using the webserver & web app. Finally, an alert can be generated and sent through an SMS or e-mail
Indication of maintenance can be achieved through voltage, dust, and sensors. Once the deposition of dirt on the solar panel is enhanced then the panel efficiency can be reduced, so this can be observed through LinkIt ONE with the values of the sensor. This data can be updated on the web server so that the maintenance time on the panel can be viewed.
Wireless Charger using Solar Energy
This project is used to design a wireless charger based on solar energy. For that, a small solar panel can be arranged on the mobile phone to charge independently without wires. Once the mobile phone is exposed to sunlight then it starts charging.
The main advantages of this project are, that it doesn’t use any wire for charging and energy can be conserved. This energy is very famous because of its abundance as well as free energy. So customer’s electricity bills, as well as money, will be saved. This energy is very clean as well as generates no dangerous waste similar to other resources of power generation.
Wireless Power Transmission using Solar Energy
This project is used to transfer energy in the form of electricity from one place to another without a connection using solar energy. The proposed system uses a solar panel to provide a renewable energy source. The solar panels charge the light energy into electrical & finally, it is stored in the batteries. This stored energy can be used by the transmitter and transmits this energy in the form of electromagnetic waves from a transmitter to the receiver using an inductor. The electromagnetic waves that are received from the transmitter are decoded to their actual form and generate the same voltage when the voltage is applied at the transmitting side.
Solar Energy-based Detection of Forest Fire
Most of the disasters that occur in the forest are fire accidents that affect the environmental impact. The main intention of this project is to detect the fire in the forest. The proposed system uses two modules namely the MAM (monitoring area module) & the FAM (forest area module). These two modules are divided into five modules again like sensors, serial communication with Zigbee, harvesting of solar energy with MPPT, and web server based on PC. The first 3 modules come under the forest area type module. These modules are connected and arranged in the forest and the webserver is developed for area monitoring.
The result of this system reveals different sensors used & the temperature sensor develops the levels of security in the surrounding areas of forests. The efficiency can be improved to 85% & the webserver can reduce the cost & weight of the whole system.
