Abstract— This AC solar panel consists of regular solar cells whose arrangement is in circular fashion mounted on a plain base. Connection of this cells is such that half of the cells are in one group forming a positive group in which cells are in series connection and half of the cells are in another group forming a negative group in which cells are also in series then these two groups are connected in anti-series connection. A disc is mounted on top of this cells which is a spinning disc, then this disc is connected to a DC motor. This motor is given supply by a buck boost circuit which is getting supplied by another set of solar cells. The disc is having slots to allow the sunlight pass through it to energize the solar cells. When the disc rotates it energize the solar cells alternately hence it produces AC power. To increase efficiency of this setup a solar tracking system is also introduced which is LDR circuit controlling DC geared motor. This DC motor controls the base of the solar cells so that the cells get the maximum solar radiations.

Keywords— Solar Cells, DC motor, Buck Boost Circuit, Sun tracking, Arduino Uno, LDR circuit.
