10. • Pin compatible with the MC146818B and DS1287
• Totally nonvolatile with over 10 years of operation in the
absence of power
• Self–contained subsystem includes lithium, quartz, and support
circuitry
• Counts seconds, minutes, hours, days, day of the week, date,
month, and year with leap year compensation valid up to 2100
• Binary or BCD representation of time, calendar, and alarm
• 12– or 24–hour clock with AM and PM in 12–hour mode
• Daylight Savings Time option

two lines of 16 characters

15. Street light applications with out using normal
power supplies.
In Remote areas implementing a small power
systems units at each home.
Using this system to getting hot water
Applications:-

16. 1.The advantage of this unit is that to run the system it
does not need computer.
2.Solar cells directly convert the solar radiation into
electricity using photovoltaic effect without going
through a thermal process.
3.During the winter the sun has a low position , tracking
angle from sunrise to sunset is shortened.
Advantages:-

17. 1.Using this system at a time we can controls only one
solar panel.
2.Higher hardware expenditure.
3.Wheather Condition Can Affect The System.
Limitations:-

18. 1. By Using controller microcontroller we can implement the intelligent
system in future.
2.In Future the conventional energy is not sufficient for use
so there is need of use non conventional energy sources
