BLOCK DIAGRAM
the block diagram of the renewable energy trainer operation. There are 4 important parts in the block diagram that is the input of resource that is 12v spotlight, 12v fan and 12v water pump that was applied with power supply. The 3 component give input to each renewable energy panel. The input was detect by each panel and sent to inverter as to invert DC to AC. Lastly, the 7 segments display the output measurement in voltage and current parameters.

Measuring Solar Panel Power Output
Load of PV panel
The power output of a solar panel depends on the resistance of the electrical load to which it is connected. In an open circuit situation (infinite resistance) the voltage of the solar panel will be high, but no current will flow and therefore no power is generated. In a short circuit situation (zero resistance) current flows, but with zero voltage and so again no power is generated. These results all follow from ohms law which gives the relationships between voltage, current, resistance, and power.A collection of power resistors of different values are required. A power resistor is a resistor which can cope with high power (and therefore heat) without being damaged. A standard 1/4 or 1/2 watt resistor will not do the job as it will overheat and be destroyed. Pictured above is a 2 Ohm resistor rated up to 50 Watts of power. power output is totally depending on the value of the resistor used.
The analysis would require instrumentation to measure 2 parameters:
- System voltage
- System current
connection of multimeter
reading and measurement
above is the video to measure PV panel using Multimeter.
Measuring Wind and Hydro power output
For wind and hydro energy, it involve of turbine parts which is it converts mechanical energy to electrical form. Therefore, to measure theturbine we have to make a reservoir that with enough pressure for the water to turn the turbine. As for educational purpose, we are replacing big turbines with suitable size of turbine so that i will be ease and less cost to build. The method use are same as Pv panel measurement that is by using multimeter to measure the 2 parameters, voltage and current output.The modification of turbine are also affect the size of control circuit that are use. As for this project, we are using mini turbine 12V DC Hydroelectric Power Micro-hydro Generator. This turbine produce output that can be measured directly.this turbine are used in both wind and hydro trainer. This turbines also use to covert the kinetic energy of the wind into mechanical energy. On the top of the large turbines there's a generator that converts the mechanical energy into electrical energy. Gears connect the generator to the turbine shaft and the electronic systems of the turbine regulate the motion in order to produce electric current of a specific frequency and voltage.The output power of the turbine are measure in power . (watts) . For wind energy the modification needed a suitable wind blade get the rotation from fan wind that applied. For hydro, the design on blade are basically to be capable of accommodating the pressure of water from the reservoir.To get the smooth and perfect rotation of the turbine, the design of blade has to be done. The design are depending on the pressure that will be applied to move the blade weight.
12V DC Hydroelectric Power Micro-hydro Generator
Features :
1. Unique hydropower separation technology, with unique dual clutch, magnetic circuit coupling volume is only about 4/5 of the normal micro hydroelectric generator, the output power is 2 to 3 times higher than the ordinary generator.
2. High efficiency, long life of waterway design and low flow loss, low water pressure, load short circuiting, also can start smoothly.

3. 4.2V/ 5V/ 12V/ 80V, total 4 models for option~
1). F50-80V : 0 to 80V DC output, generator without regulating circuit, peak voltage reach 80V, can be directly charging for 3-12V 10W LED lights or for small storage battery, the charging current is 220 ma, because when charging the battery in the same time it also being used in a timely manner, so the voltage automatically maintain at about 14V, so it can keep the right voltage for the storage battery charging.
2). F50-12V : 12V DC voltage output, can give the power or recharge for the radio with 12V working voltage, or for the LED.
3). F50-4.2V : 4.2V DC output, can recharge for the ordinary lithium battery etc.
4). F50-5V : 5V DC voltage output, can charging for the mobile phone, can also recharge for the ordinary lithium battery with management chip etc.
Specification :
1. Water inlet/outlet : 1/2"
2. Output Voltage : 4.2V/ 5V/ 12V/ 80V
3. Max power : 10W
4. Output Current : max 220mA
5. Outlet closed highest pressure : 0.6MP
6. Outlet opening the highest pressure : 1.2MP
7. Startup pressure 0.05 Mpa
8. Working Temperature Range : 5°C ~ 85°C

Idea for developing this project
Base on the tittle for this project, the main element that use is the renewable energy of solar, wind and hydro. In order to create a prototype of renewable energy trainer. The suitable design are modified from the size and operation of each system. Therefore, the design of the trainer should fit the size of component and material that use to make the trainer. As for understanding, the project purpose is to give an comfortable, safe and easy to use for users. The aim of this project is to give an understandable procedure as the trainer target is for student and education purpose.
In making the idea, the sources that use for this project had to be replaced by other sources that is available and can be use in indoor usage. spotlight, fan and water pump are the additional parts that is installed to replace the renewable energy.
