no, you cant actually start a car with 8 AAA batteries. Eight AAA batteries do add up to 12 volts, but they still can’t provide enough electrical current to run the starter motor. But that’s not the whole story. Any battery has a limit on the maximum current it can produce. To explain why, we have a model to represent a real battery.
Sitting at home in the summer heat, your mind may start to wander to that fancy new air conditioner. But when it comes to making your house comfortable and sustainable, prevention is better than cure. By prevention we mean simple retrofits that will set you on the path to comfort and sustainability. As we spend more than ever on maintaining and improving our homes, we’re also becoming more aware of how their design and use impact on our health and society. Add to this climate change and rising energy costs.
CARBON DIOXIDE (CO2) Carbon dioxide is an odorless gas and a minor constituent of the air we breathe. It comprises only .03 % (300 parts per million, or PPM) of the atmosphere but is vitally important to all life on this planet! Plants are made up of about 80-90 % carbon and water with other elements like nitrogen, calcium, magnesium, potassium, phosphorous and trace elements making up only a small percentage. Almost all of the carbon in plants comes from this minor 300 PPM of carbon dioxide in the air. Plants take in CO through pores, called stomata, in their…
Install for less, harvest more energy The ConextTM MPPT 80 600 solar charge controller offers an industry-first set of integration features and top performance that allows for large PV array systems to be easily installed and connected to the battery bank at the lowest overall cost. Installing one MPPT 80 600 is faster than installing multiple smaller charge controllers and lowers overall costs further by utilizing fewer PV strings, smaller wiring and conduit, and by eliminating the need for PV combiner boxes and DC circuit breakers.
The mainstreaming of affordable and energy-efficient small and tiny homes into our cultural consciousness has picked up tremendous momentum in the last few years, leading many to characterize it as a movement in its own right. Even though tiny homes won’t be a fit for everyone, they could potentially help address critical issues like over-consumption and debt, while growing alternative and more sustainable building practices on a larger scale and making housing more affordable.
It is a photovoltaic (PV) system interacting with the utility, with or without batteries, that uses a relatively new breed of inverters that can actually sell any excess power produced by your solar array back to the utility grid. If you are concerned at all about your utility rates going up and would like to do something to reduce your monthly electric bill, then a grid-tie solar system may be just the thing for you. These systems are easy to install and since some do not have batteries for back-up, the lack of batteries in these systems means no messy maintenance or replacements…
Buyer Beware. Falling costs and increasing adoption are wonderful news for clean energy, but now is not the time for celebration. A new report from the U.S. Department of Energy suggests that the costs of renewable technologies are tumbling, and with it their adoptions soaring. But despite the good news, we can’t become complacent.
San Diego, Calif. — Bifacial PV modules have been in the market for some time, but with limited usage. The BIPV applications such as awnings and canopies have been a niche market for bifacial PV modules because of glass-on-glass, see-through, aesthetic looks. They have also been used, because of their vertical install-ability, as railings or sound barriers at highways and railways or other places where space for installing standard PV modules is limited. But, are bifacial PV modules ready for larger deployment in the growing PV industry?
Using a simple membrane extract from spinach leaves, researchers from the Technion-Israel Institute of Technology have developed a bio-photo-electro-chemical (BPEC) cell that produces electricity and hydrogen from water using sunlight. The raw material of the device is water, and its products are electric current, hydrogen and oxygen. The findings were published in the August 23 online issue of Nature Communications.
In case you’re searching for the sun panel of the future, why no longer don’t forget those created via the aptly-named SolarWindow technology, which transform regular home windows into photovoltaics, capable of generating 50 times greater electrical power than rooftop panels, while modeled for a 50-tale building. “Simply choose up your mobile phone, observe the face without any strength or photo, and also you’ll see a quite accurate instance of what today’s thin film looks as if,” John Conklin, CEO of SolarWindow, instructed digital trends. “It’s heavy, it’s too darkish to peer via, and most skinny-film is not bendy. This…
