What happens to solar power when it isn't sunny? A simple question with an amazing answer.

" has been a question for pretty much about as long as solar energy has been a thing. Of course people wouldn't want solar panels on their houses if installing them meant that, come sunset, the movie they were watching suddenly shut off, forcing them to read by candlelight like colonial settlers. Making solar power a viable option, even when the sun sets or disappears behind some clouds, was one of the first things scientists and engineers had to figure out. Photo by Andreas Rentz/Getty Images. When the first devices that could capture the sun's energy were invented, they weren't very efficient. Passive Solar Heating Basics.

Posted Categories: Construction Methods The very root of what makes a home green is how effectively it responds to its surrounding environment.

Passive Solar Heating Basics

You could say that this has defined the primary material pursuit of mankind for all time – building better shelters to keep us warmer, cooler, and drier. Many of the native building techniques employed centuries ago are still reliable in similar climates today, and used as optimal models for environmentally conscious architects. That said, since global acceptance of the air conditioner in the 1950s, the benefits of responding to a unique climate have been left by the roadside. The principles of passive solar heating, such as basic types of systems, their description, and the components making up any passive system are presented in this course. How Much does an Average Solar-Panel System Cost? If you’re shopping for a solar energy system, one of your first questions is probably, “how much will it cost?”

How Much does an Average Solar-Panel System Cost?

Prices depend on the size of your system, the type of equipment you choose, and the state that you live in, but reviewing prices for a 5 kilowatt (kW) system is a great place to start – that’s the average system size in the United States.

Nigerian Man Turns A VW Beetle Into A Solar And Wind Powered Car

Segun Oyeyiola was a student at Obagemi Awolowo University and while he was in attendance there, he converted his gas thirsty Volkswagen into a completely green energy machine by installing a large solar panel on the top of the car, with an additional wind turbine underneath the hood. His idea is to have his concept of his new invention to become “Nigeria’s future car.” At birth, the battery took 4-5 hours to charge, that was definitely not ideal. Yet the largest challenge, according to Mr. Oyeyiola, was obtaining the best materials to use, and it didn’t help at all being surrounded by people telling him that he was wasting his time.

Check out this animation of a solar/wind-powered vehicle, illustrating how the batteries are charged via the multiple turbines. Under the hood of this bad boy boasts three wind turbines that transfer air into energy and is then stored in the main battery. Nikola Tesla - Solar Panels That Roll Out Like Carpet! New Catalyst Lets Us Store the Power of the Sun. In Brief Scientists have found a way to “crack” water three times more efficiently using solar- and wind-generated electricity, which means it’s possible to store renewable energy for later use.

New Catalyst Lets Us Store the Power of the Sun

Rainy Day Energy One of the problems with using renewable energy sources is that you’re overly dependent on the fickle whims of weather. Drawing power from the Sun is fine, but what happens when it’s overcast? Or, if using wind energy, what do you do when the breezes are unusually still?

Well for the first couple weeks we moved into our home, that’s exactly what it was like! But we’ll get to that. South African team may have solved solar puzzle even Google couldn't crack. It is a problem that has so far stumped even Google’s brainy engineers – how to generate cheap solar electricity using a small-scale array of mirrors to concentrate the sun’s energy.

South African team may have solved solar puzzle even Google couldn't crack

Now a team at a South African university – led by a former Intel strategic planner – believes they have cracked it. Once they have completed a prototype system in October they have big plans for rolling out the technology. The idea behind the design – so-called Concentrated Solar Power or CSP – is simple.

A field of mirrors on the ground tracks the sun and concentrates its rays on to a central point which heats up. 7th Grader mimics Nature. 13 year old copies Nature to Improve Solar Performance Thirteen year old Aidan Dwyer was walking in the woods in Upstate New York in the winter and noticed a spiral pattern to tree branches.

7th Grader mimics Nature

Aidan realized the tree branches and leaves had a mathematical spiral pattern that could be shown as a fraction. After some research he also realized the mathematical fractions were the same numbers as the Fibonacci sequence. "On the oak tree, the Fibonacci fraction is 2/5, which means that the spiral takes five branches to spiral two times around the trunk to complete one pattern. Other trees with the Fibonacci leaf arrangement are the elm tree (1/2); the beech (1/3); the willow (3/8) and the almond tree (5/13) The Solar Conundrum. The Solar Conundrum: heat decreases the production of electrical energy in PV.

The Solar Conundrum

Hybrid Vacuum Tubes.By efficiently drawing heat away from the solar panel for space heating, hot water, de-salination and cooling the photovoltaic cells are maintained at an optimum operating temperature. This results in significantly higher electrical output than standard photovoltaic panels. This type of device is commonly referred to as PVT. Both energy outputs are optimized replacing the need for two separate conventional panels (PV and Thermal), dramatically reducing installation time and cost whilst maximizing useable installation area. Through its unique patent pending design, V3Solar is able to concentrate up to 150X more sunlight on 1X sun mono PV without the cells overheating. Light is transferred to electricity in nanoseconds. The V3Solar patent pending design also delivers a higher level of efficiency from PV. Spherical Solar. Solar Sphere Concentrated photovoltaic (CPV) technology never looked so good.

Spherical Solar

The Rawlemon Solar Energy Generator was a finalist in the World Technology Network Award Dec, 2013. The inovative design is much more efficient than a flat pv panel as the round orb concentrates and tracks the sun's light. The inventor, German born, Barcelona-based architect André Broessel, with his first large scale prototype, which sits a top his Barcelona apartment building. The concentrator is essentially a giant glass orb on a robotic steel frame. Because of the concentration of light, the cell area under the water-filled orb is 75 to 95% smaller than a flat pvc with the same output.

The device incorporates a fully rotational weatherproof natural optical tracking device that functions on inclined surfaces and curtain walls, therefore any sun-facing building surface will be suitable for application.

One aspect of construction that I neglected when building Tiny House Ontario was what I would do about electricity.

To tell you the truth electricity scares me because it carries the power of fire. Even so, I thought about it enough to know that I did not want to be on grid, and that I wanted to do it myself. After living there, two seasonal years, I knew that my need for electricity was very limited. I did not require refrigeration, a TV, or any other appliances; I desired some light to read at night, a fan on hot nights, as well as the ability to charge my cell phone, computer and drill. 15kw Solar Power Plant.

Solar Thermal – An Old Concept for Today’s World. Some people think the concept of solar thermal is radically new. Truth is – people have been using the power of the sun for decades to provide hot water. But catching the sun’s rays hasn’t always been an easy task. Throughout the years, many creative solutions have been devised to help generate solar-heated water. Early on, people used a black-painted water tank, mounted on a roof, to gather the sun’s rays. Today, however, a variety of solutions are available to anyone looking to harness the sun’s energy for water heating purposes – and they promise to be far more effective, efficient, and attractive than a black tank on your roof.
