Sun Tracking Solar Panel System
I have been thinking about some green ways of depending on the grid as much as I do. There are so many things that can be done but most are very expensive unless you use some build some of it yourself. Have a look at this solar and wind system that uses some home made sun tracking units. "The systems tracks the Sun using a controller from Red Rock Energy and a Satellite Jack Arm. The tracking device is custom made.

Sun Tracking Solar Panel : Undergrad Project funded by DST, Govt of India - Sampriti Bhattacharyya
The Sun Tracking Solar Panel was an idea derived from the project on Space Technology, in my sophomore year. We found that, if a rover had rotating solar panels that would always point towards the sun, it could have a considerable increase in it's efficiency, theoritically as much as by 50%.With this in mind, I worked on a programmable Sun Tracking Panel which would track the sun althrough the day and at night and retrace it's steps back to the east at night to face the sun again, the next day. This project got approved and funded by Department of Science and Technology (DST, India) Originally I wanted the panel to have motions in two axis, but we only made a simplified version, as a part of a renewable energy project. If you are interested in building one, I still have a two axis design. Other members of this project are Santu Datta, Abhinanda Basu and V. The panel uses photodiodes to locate the sun and is has stepper motors controlled by the ARM 7 microcontroller. Detailed Description:

Economy : ‘Narmada canals can give 2,200 MW of solar power’
It will also save 11,000 acres of land, says Gujarat CM Mehsana (Gujarat), Apr 25: If even 10 per cent of the 19,000 km-long Narmada canal network in Gujarat is used for setting up canal-top solar panels, it has the potential to produce 2,200 MW of solar power, save 11,000 acres of land that would otherwise be used and prevent 2,000 crore of precious water from evaporation annually, the Chief Minister, Mr Narendra Modi, said. Also, canal-top solar power equipment produces 15 per cent more power than the plant set up on land as the water flowing underneath keeps the solar panels relatively cool and helps generate more power, he said. The State Government was compelled to take up this project through Gujarat State Electricity Corporation Ltd (GSECL), as no developer was ready to take the challenge at that time, he said. The length of the Narmada Main Canal, constructed under the Sardar Sarovar Project (SSP), is 458 km. New tech (This article was published on April 25, 2012)
Solar Tracker - How To Build
Here comes the sun
Just outside Seville, in the desert region of Andalucia, Spain, sits an oasis-like sight: a 100-meter-high pillar surrounded by rows of giant mirrors rippling outward. More than 600 of these mirrors, each the size of half a tennis court, track the sun throughout the day, concentrating its rays on the central tower, where the sun’s heat is converted to electricity — enough to power 6,000 homes. The sprawling site, named PS10, is among a handful of concentrated solar power (CSP) plants in the world, although that number is expected to grow. CSP proponents say the technology could potentially generate enough clean, renewable energy to power the entire United States, provided two factors are in ample supply: land and sunlight. Now researchers at MIT, in collaboration with RWTH Aachen University in Germany, have come up with a design that reduces the amount of land required to build a CSP plant, while increasing the amount of sunlight its mirrors collect.

Lenses & mirrors Sunlight The Energy Advocate
Lenses and mirrors can be used to concentrate sunlight. All schoolboys know that a magnifying glass can focus sunlight into a small spot to create very high temperatures. Concentration is not creation, of course. A 2-inch diameter magnifying glass concentrates the sunlight into a small spot, but it also leaves a 2-inch diameter "shadow" where sunlight is not present. The small spot is nothing more and nothing less than an image of the sun. The larger the lens, the more sunlight it gathers, and presumably the hotter the spot. But temperature and heating power are two different things.

This is going to make solar affordable for everyone. This is a very standard prototypes solar furnace made of lens for all recycled big screen television. I placed it in little bit frame, near the focus here we have a heat collector and a heat exchanger we can run water through to generate high pressure steam. We can generate approximately 1.2 kilo watts of heat energy for this lens. This is about 60 inches (1.52 meter) in diameter using nothing but sunlight. This is a basic solar thermal generator I have come up with. The idea is to take the heat of the sun and use it to generate electrical power as well as hot water. How much power will this system produce?
Solar thermal energy
The first three units of Solnova in the foreground, with the two towers of the PS10 and PS20 solar power stations in the background. Solar thermal energy (STE) is a technology for harnessing solar energy for thermal energy (heat) requirement in industries, residential sector and commercial setup. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors. Low-temperature solar heating and cooling systems[edit] Systems for utilizing low-temperature solar thermal energy include means for heat collection; usually heat storage, either short-term or interseasonal; and distribution within a structure or a district heating network. Heating is the most obvious application, but solar cooling can be achieved for a building or district cooling network by using a heat-driven absorption or adsorption chiller (heat pump). Low-temperature collectors[edit] Unglazed, "transpired" air collector Interseasonal storage.
Compendium of solar cooker designs
Introduction The main purpose of this compilation is to present all possible major designs and their variations so as to prevent the solar cooker designer from wasting time creating a design which has already been under the sun. Concentrator Types Concentrator cookers offer several advantages, including a mode of cooking very similar to day to day cooking. Solar cookers that concentrate light from below Heat coming from below is most convenient for routine cooking, hence, many designers have focused on this type of cooker. Solar cookers that concentrate light from above In this type of solar cooker, the light is concentrated from above. Solar box cookers Box cookers are another group of old but popular solar cookers. The box cookers presented here are classified on the basis of the presence or absence of reflectors, i.e., those without or with mirrors boosters. See also Principles of Solar Box Cooker Design. Indirect Types Selecting the best design Evaluation of cookers See also Testing. Safety
