Photo voltaic Suitcase: Self-Contained Moveable Photo voltaic Energy Station -Moveable Photo voltaic Energy Station: Photo voltaic Suitcase I’m an enormous fan of solar energy programs, particularly, these you may construct your self. However, I perceive if you would like one thing that’s already executed for you. Enter the moveable solar energy station within the type of the Photo voltaic Suitcase. (at the moment on sale for $349)
1. Photo voltaic Powered LED Road mild with auto depth management:
LED based mostly road lights owing to their excessive effectivity and ease of depth management at the moment are continuously changing the traditional HID based mostly road lamps. This mission defines a LED based mostly mild system which is energy from a solar energy supply and their depth may be managed such that they’re switched on with most depth solely in the course of the peak hours. The output from photo voltaic panels is saved throughout day time, in batteries and at evening this battery is used to energy the LEDs.
Right here on this mission, an array of LEDs are used to symbolize the road lights. A cost controller unit is used to sense irregular situations like over charging, overload and low charging situations and accordingly management charging of the battery. The DC energy saved within the batteries is used to energy the array of LEDs by way of a change association. The depth of the LEDs are managed or assorted after explicit time intervals by offering various responsibility cycle pulses to the change from the microcontroller. Thus utilizing PWM method, the solar energy is provided to the LEDs to range their depth.
2. Solar Monitoring Photo voltaic Panel:
This mission defines a manner for mounting of photo voltaic panels in order to obtain most radiation from the solar. Right here an energetic tracker system is used the place the panel is positioned on the shaft of a motor and the motor is given correct rotation such that the panel is at all times oriented at 90 levels to obtain the utmost daylight.
3. Photo voltaic Energy Cost Controller:
One of many important components of a solar energy system is the cost controller which is used for controlling the cost to the battery. As we all know, in a solar energy system, the photo voltaic vitality collected by the panels is saved in batteries as a way to be used at evening instances. Additionally this DC energy is transformed to AC energy utilizing inverters. Right here a system is designed to realize the management of charging of the battery.
Right here comparators are used to sense any irregular situation like over charging, low voltage or overload situations and accordingly give output to regulate the charging of battery. A reference voltage is about utilizing a possible divider association. Incase of overcharging, the indication is given by the glowing of LEDs and the present from the panel is bypasses by way of the transistor. Incase of low battery voltage and over load, the load change is made to be in off situation and the provision to the load is cutoff. Thus the charging and discharging of the battery is managed.
4. Photo voltaic Powered Auto Irrigation System:
Irrigation is synthetic provide of water to areas with scant rainfall or water provide. It’s typically required to regulate the provision of water by sensing the moisture content material within the soil. This mission defines a solution to obtain this by utilizing a pump which is powered by photo voltaic vitality, in order to beat the frequent unavailability of mains provide and controlling the switching of the pump motor based mostly on the sensor enter which senses the moisture content material within the soil.
5. Photo voltaic Power Measurement System:
This method is used to watch completely different parameters associated to the photo voltaic panel like temperature, mild depth, voltage and present and show the parameters on a LCD show.
Right here Four sensors are used to sense the completely different analog parameter, i.e. temperature, mild, voltage and present. These parameters are sensed utilizing sensors for every parameter. The output from the sensors are fed to the enter pins of the PIC microcontroller with inbuilt 8-channel ADC with Four of its channels getting used. The output from the sensors is then accordingly displayed on the LCD show in digital kind.
