Abstract - AC Solar Generator works on a very simple
the DC power of solar cells directly to AC without use of any conversion equipment’s. The resulting output voltage is thus sinusoidal or AC. Thus there is no need of conversion equipment’s such as inverters, phase synchronizers, etc. This makes the overall concept quite simple yet effective and economical as well.
principle. It consists of standard solar cells arranged in circular pattern mounted on a base. Half of the cells are wired in one circuit and half in another circuit. Mounted above the solar cells is a spinning disc powered by a DC electric motor. The DC motor gets its power from four small DC solar cells mounted in the corners of the base. The disc has portals cut into it allowing light to pass through to every other solar cell below it. As the disc spins each of the banks of solar cells is alternately exposed to light and alternately produce power. When the portal is halfway between the two cells the voltage cancels and drops to zero. The resulting voltage is sinusoidal or AC. Thus there is no need of conversion equipment’s such as inverters, phase synchronizers, etc. This makes the overall concept quite simple yet effective and economical as well as compared to the current trend of extracting the solar energy in the market.
2. PROPOSED SYSTEM Solar input which the never ending source of energy is and which is readily available is used as an input. This reduces the ever increasing demand for fossil fuels such as coal, petroleum, diesel etc. The DC motor is used for driving the disc mounted above the solar panels. This motor will drive the disc at a constant speed. This motor will be supplied from the power generated from the solar panels.

1.INTRODUCTION Fig -1: Flowchart of I/O Power Utilisation
There is a current global need for clean and renewable energy sources. Fossil fuels are nonrenewable and require finite resources, which are dwindling because of high cost and environmentally damaging retrieval techniques. So, the need for cheap and obtainable resources is greatly needed. An efficient and more feasible alternative option is solar energy. Solar energy is a more practical type of energy due to its plentiful availability; it is derived directly from the sun.
The disc has portals cut into it allowing light to pass through to every other solar cell below it. As the disc spins each of the banks of solar cells is alternately exposed to light and alternately produce power. The solar cells are arranged in such a way that it gives us the output in sinusoidal form.
3. CIRCUIT DESCRIPTION 3.1. Panel Arrangement
One of the problems which hinder the use of solar energy extensively is the cost of extracting the energy and then converting it into suitable form according to its applications. The price of solar panels combined with the price of inverters, phase synchronizers, installation and maintenance has made the price of solar prohibitive. Add to that the loss of power from the different components used in the DC to AC conversion process and it becomes even more unattractive. AC Solar Generator eliminates the problem of converting DC to AC. It uses solar as its input and with the help of a motor-disc arrangement it converts

The solar cell a/c electricity generator has a base that supports the various components thereof. The base may be formed of wood, plastic or other suitable material which is preferably, but not necessarily, a non-conducting material. The base includes an alternating current electricity production portion formed by a disc and a plurality of photovoltaic or solar cells.
