DIY Green Solar Energy

If you are planning to cut your electricity bill in half you are not in the right place. In this tutorial i show you how to cut solar cells and make a small robust solar panel for charging a battery. Made this way they can last for years (i hope) Gretings Roger

www2.dupont.com Title: City of Science, City of Hope While our world holds many high hopes for solar energy, comprehensive city-sized applications remain few and far between. Masdar, Abu Dhabi’s stunning new sustainable development, is a living laboratory dedicated to proving the viability of green technologies at a citywide level. The city looked to Suntech to provide this photovoltaic technology. When it came to manufacturing the thousands of panels required for the landmark project, Suntech turned to DuPont to deliver a number of crucial components to ensure maximum efficiency and reliability. This collaboration is already yielding results—Masdar is currently consuming only 40% of the energy they are generating. NOURA AL DHAHERI PHD STUDENT, MASDAR INSTITUTE After having a son, I began to be more concerned about his future. The way we live now, burning the fossil fuel, we need to step up and do something about it. TITLE ABU DHABI MAIN TITLE CITY OF SCIENCE, CITY OF HOPE ALAN FROST DIRECTOR, MASDAR CITY Masdar, for me, is like no other project in the world. The idea of the city itself was to be carbon neutral. The architecture is based on all Arabic cities. The narrow streets are very important to keep out the sun during the day. At the moment, we’re testing a personal rapid transport—that’s a driverless electric vehicle and it’s powered from our solar farm. NOURA AL DHAHERI We’re kind of living in our laboratory, and we know that, but we are happy because this is what …

In theory, connecting 2 solar panels in parallel of similar voltage rating, should not impact the power output of a shared Grid Tie Inverter (the wattts should add). This video shows that there are losses, and that the power does not add up. It is best to have each panel on their own grid tie inverter, at least in the case of these cheapo ones.

This is a tour with details of an off-grid solar power installation I worked on a few years ago. I go over a system diagram, show the system itself, and then talk about the safety features including breakers/fuses, lightning arrestors, and bonding equipment to ground. This system includes 2100watts of solar panels, a 10kW diesel generator, two Outback FM-80 charge controllers, two Outback inverters, an Outback Mate, a Xantrex TMA-500 battery status monitor, and 6 4volt, 1104amphour Surrette/Rolls lead acid deep cycle batteries. Thanks to Ottawa Solar Power (ottawasolarpower.com) for allowing me to use this installation in this off-grid solar power video. For more on solar power, see rimstar.org – rimstar.org

University of Texas at Austin’s Manor Parking Garage is now solar powered. Three different types of solar panels provide shade to rooftop parking as well as valuable research data for University students and professors.

Using sustainable energy to improve people’s everyday lives is at the heart of our mission, and we are proud to work with Patrick Dempsey to draw attention to the difference that solar energy can make in this world. To learn more, please visit trinasolar.com/15minutes

greenpowerscience.com The starting temperature was 80f (27 C) and a full boil was obtained in 90 seconds (+-10 seconds). The dish is a 10 feet (3 Meters) diameter with a large acrylic mirror for the center. Focal length is 5 feet (1.5 Meters) from the base. The mesh panels are covered with Part A and B material from our website and also regular .118 acrylic mirror sheets. The focal point is 1″ diameter from the acrylic mirror and 4″-8″ diameter from the satellite dish. The vacuum tube holds 20 ounces and it was full.

Determining the efficiency of Sun and Power Jack Grid Tie Inverters at input power levels under 100 watts. Also shown is the method to measure and calculate efficiency for your solar PV system. In my prior video, efficiency at high wattage was measured.

Some FOOL thinks cleaning solar panels actually matters!! LOL !!
