    A new multilevel solar panel system is proposed for its use in urban residential solar home systems. The proposed system consists of three panels mounted in a rack one above another at a fixed distance from each other to minimize the floor area while shifted horizontally from each other by half the panel width to avoid shading of the lower panels. In the proposed system, the panels will be fitted with a tracking system to track the sun to maximize the energy collection. Further, a gliding mechanism is perceived for the panels that will enable the panels glide both ways and realign as the sun moves from east to west to avoid shading. Initial calculation, done for March 21st, shows that the proposed multilevel three panel system can harness 18.6% more energy than the three conventional fixed panel systems with 33% less area. The proposed system will be useful for large urban city dwellers, especially in third world countries, where not only electricity is in short supply, availability of roof top space to install solar panels is also very limited.

    A two-seater light-weight solar powered clean car: preliminary design and economic analysis
    (© 2014 Institute of Electrical and Electronics Engineers Inc., 2014-07) Ahmed, Sanjana; Zenan, Ahmed Hosne; Rahman, Mosaddequr Abdur; Department of Computer Science and Engineering
    This paper outlines the design of a prototype solar powered light-weight economically affordable clean car for the daily office commuters of Dhaka city. Calculation in this paper shows that the solar power alone will be sufficient to operate a light-weight car from one end of the capital city Dhaka, to the other, for a journey to and from the office. A preliminary design of the solar car has been performed in this paper by calculating and estimating the required panel size, battery capacity and motor power. A plug-in charging option has been supplemented to the car for extracting electricity from the mains during times of insufficient energy receptions from the sun. Economic analysis performed on the life cycle cost of solar cars, as opposed to traditional fuel-based cars shows that over the long-term, solar cars come out to be much less expensive. Over a period of 20 years, combined cost of solar component replacements and electricity charges amount to a total over BDT 2 lac, which is approximately 1/9th the total cost of operating a fuel-based car in Dhaka, considering the fuel cost, maintenance and annual inflation over the same duration.
