After the preliminary study, it was discovered that a D.C motor in combination with two gears can produce the required t >ffect on the screw at less amount of time, thus eliminating the use of manually operated lever and the corresponding inconve hat goes with it. The next step involved choosing the appropriate servomotor (because of its ability to provide high torque) < -orresponding gear ratio to transmit the torque. However, the choice of thread on screw and nut, after calculations on appr nternal and external diameter was chosen. Single point cutting tool was used in the cutting of the required links, while hamm shaping machine were used to bend them to shapes. Components assembly and balancing on roads was done while sonsideration to torsion, bending and shear forces acting on strategic point. It is important to note thatiterative comparison of values obtained, with those required for safe operation (yield stress) was made and the cycle repeated when necessary. Jsing the methodology and principle of manual jack whichworks on the bases of when the threaded shaft of a manualjack is nanually using a T-handle in a clock wise direction, this causes the jack to contrast thus lifting the load and when anticlockwise brings the load down. So therefore, the powered toggle jacks works on this principle but the difference is tl uring of the threaded shaft in the jack is not done manually but with the aid of an electric motor. The methodology of the pc oggle jack is simply on the conversion of electricenergy to mechanical energy so as to lift load [5].

a ina 2 In isolated systems away from the grid, batteries are used for storage of excess solar energy converted into electrical energy. The only exceptions are isolated sunshine load such as irrigation pumps or drinking water supplies for storage. In fact for small units with output less than one kilowatt. Batteries seem to be the only technically and economically available storage means. Since both the photo voltaic system and batteries are high in capital cost.
