Design of Solar Tree and Its Application in Rural and Urban Households in India

In this paper, 3-D star tree model of solar panel is introduced. Here, the step up motor is controlled by raspberry pi microcontroller to automate or synchronize the whole system with the position of the sun to gain maximum energy. It is well known that Sun is the greatest energy source for earth but we are unable to utilize it effectively and efficiently. In this paper we employ photovoltaic (PV) cell for converting solar energy into electric energy. Nowadays, PV cells made of semiconductor materials like crystalline silicon, thin film and multi-junction solar cell, are used which are cost effective and highly efficient. In India, there are number of sunny hours per year. We receive solar radiation in a range of 4 to 7 kWh/m2/day, but people do not have much space to install the solar energy plant and hence they are not able to utilize the solar energy effectively which is the main reason that electricity is the major problem. In this paper the Design of our solar tree model is bio-inspired so that solar panel can absorb more sunlight similar to the leaves of a natural tree. The spiral arrangement of leaves on the stem or the branch is called Phyllotaxy. The leaves spiral around the stem or the branch in a regular pattern hence the design is called solar tree.
