Design of DC Motor Driver for Solar Tracking Applications Abstract - Solar trackers rely on a direct-current (DC) motor driver circuit to control the movement of the solar panel. However‚ conventional DC motor drivers used in solar tracking system do not provide any options for speed and torque control. Hence‚ the fixed speed of the DC motor leads to either too fast or too slow tracking movement. Usually‚ the output torque is set to the maximum. If the load (solar panels’ weight) is small‚ the

money to develop solar energy‚ such as‚ solar thermal energy in order to establish a sustainable‚ clean‚ responsible and efficient form for energy for generations to come. While solar energy startup and even maintenance costs can be just as expensive as oil and coal production‚ solar energy is undoubtedly worth the price in the long run‚ even solely for the benefit of CO2 reduction. As far as using solar thermal energy locally‚ my hometown of Bloomington‚ Indiana currently uses solar thermal energy

Planets and moons in our solar system share many similar properties‚ but there are also many ways they are different. Some of the main differences come with the different geologic activity‚ composition‚ interior structure‚ magnetic field‚ and atmosphere that distinguish some planets and moons from others. The first way to separate the planets as far as their surfaces is breaking them into their two categories. The Jovian planets (Jupiter‚ Saturn‚ Uranus‚ Neptune) are primarily composed of gas and

The Illusion of the Capital Gains Tax Increase Policymakers and researchers have long been interested in how potential changes to the capital gains tax system affects the health of the overall economy. A capital gain is the increase in the value of a capital asset realized over its cost basis (Saxton). The lower tax rate for capital gains is the policy that the United States has followed from the inception of the income tax‚ a policy followed by almost every other advanced economy on earth. As numerous

Audience: American homeowners Conserving Energy to Save Money According to an article and graph published in The New York Times‚ “About 56 percent of all the energy that is produced in the United States is wasted” (Revkin). With all that energy being wasted‚ Americans cannot afford to waste much more. There are a number of things a homeowner can do around and to their household to conserve energy and save money at the same time. They can turn off unneeded electricity and try other sources‚ such

Can Solar Energy be a viable alternative for electricity generation in Nepal? “The sun bathes the earth in a steady‚ enormous flow of radiant energy that far exceeds what the world requires for electricity fuel.” The last decade has been harsh enough for the people of Nepal. The power cut being hiked up to 16 hours a day in 2009 provides testimony to the fact that Nepal has been hard hit by energy crisis. Given the over-increasing population‚ along with rapid industrialization and urbanization
