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 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 the coastal areas like Gujarat, 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 solar energy-based water purification system which works on the principle of reverse osmosis.

Solar Powered LED Street Light Here in this project, an array of LEDs are used to represent the street lights. A charge controller unit is used to sense abnormal conditions like overcharging, overload, and low charging conditions and accordingly control charging of the battery. The DC power stored in the batteries is used to power the array of LEDs through a switch arrangement. The intensity of the LEDs is controlled or varied after particular time intervals by providing varying duty cycle pulses to the switch from the microcontroller. Thus using the PWM technique, solar power is supplied to the LEDs to vary their intensity.

At a certain period, the stepper motor is given 90-degree rotation so as to receive the maximum light. Please refer to this link to know more about Sun Tracking Solar Panel Solar Power Charge Controller One of the essential parts of a solar power system is the charge controller which is used for controlling the charge to the battery. As we know, in a solar power system, the solar energy collected by the panels is stored in batteries in order to be used at night times. Also, this DC power is converted to AC power using inverters. Here a system is designed to attain the control of charging of the battery. Solar Power Charge Controller Here comparators are used to sense any abnormal condition like overcharging, low voltage, or overload conditions and accordingly give output to control the charging of the battery. A reference voltage is set using a potential divider arrangement. In the case of overcharging, the indication is given by the glowing of LEDs and the current from the panel is bypasses through the transistor. In case of low battery voltage and overload, the load switch is made to be in off condition and the supply to the load is cut off. Thus the charging and discharging of the battery are controlled.
