President Obama mentions facts from our Solar JOOS blog during his State of the Union speech

During this year’s State of the Union address, President Obama used in his speech, facts from our Solar JOOS blog which were provided to us by GTM Research.
In our article “Solar Statistics for 2013,” we provided a fact given to us by GTM Research that every 4 minutes, a new solar system is installed in a home or business. We wrote, “2013 saw a shift to the U.S. becoming a global leader in solar. At our current pace, every 4 minutes, another American home or business goes solar.”
President Obama stated, “we’re becoming a global leader in solar, too. Every four minutes, another American home or business goes solar.”
We’re glad to see the president is putting the focus on the importance of solar energy in America by bringing up these facts and figures in his State of the Union speech. If President Obama is interested in any other solar energy facts, we’d love to provide them to him or direct him to the real experts over at GTM Research.

What is MPPT (Maximum Power Point Tracking) and why does it matter with solar?

What is MPPT (Maximum Power Point Tracking) and why does it matter with solar?

MPPT ChartMPPT (Maximum Power Point Tracking) charge controllers are a commonly found component in today’s battery-based renewable energy systems although they’re not commonly found in the smaller, portable solar chargers. The JOOS Orange from Solar Components is different—it has a proprietary MPPT circuit that allows the small, portable device to achieve amazing efficiency and charging capabilities not found on competing products.
But what exactly is MPPT? MPPT control reduces wasted energy by operating the photovaoltaic solar module at its higher MPP (Maximum Power Point) voltage and lower MMP current, instead of the lower power obtained by connecting the photovoltaic directly across the battery terminals. This higher voltage in turn helps to keep price down, especially when the PV wire runs are long because the current is lower for a given amount of power.
Raising the controller’s PV limits higher gives a buffer for when part of the PV cell becomes shaded by trees, clouds, or poles. We want to keep the MPPT voltage above the battery voltage as much as possible and MPPT allows us to do that.
MPP tracking efficiency has also improved to almost 100% accuracy. Algorithms that can quickly scan the entire I-V curve of the PV array from battery voltage up to Voc (Open Circuit Voltage) ensures that the correct MPP “bump” is chosen from multiple possible power points with as little time away from the correct power point as possible.
So now that you understand what MPPT is and what it does, you may be wondering why Solar Components would put such powerful circuitry in a small, portable solar charger. The reason is simple: “When we set out to design and build the JOOS Orange, we wanted a device that was light years ahead of our competition and more importantly, we wanted a solar charger that would actually work,” said Mark Sherwood, the company’s president. “With our proprietary MPPT circuitry, we are able to offer a more efficient and technologically advanced product than what our competition is able to offer, for about the same price.”
The JOOS Orange can be purchased by itself for $149, or as part of a bundle that includes the JOOS Orange, PowerBoost Reflectors, and a sturdy neoprene protective case for $175.

Renewables provide 99% of all new U.S. electrical generating capacity in October

Renewables provide 99% of all new U.S. electrical generating capacity in October

renewables-1694 megawatts of new electrical generating capacity was added last month, of which, 99.3% comes from renewable sources including 72.1% from solar energy. The remaining 5 megawatts came from oil.
Twelve new solar energy generation units were put in place to produce 504 megawatts of generating capacity, followed by four biomass units generating 124 megawatts and two wind energy generation units adding 66 megawatts to the grid.
So what does this mean for solar energy? It means we as a society are taking a more serious look at how beneficial harnessing power from the sun can be and how it can help us move away from non-renewable sources we’ve been dependent on for years.
Now not all of us have the financial resources to install a solar array on our homes or in our backyards but we can help do our part by charging our personal electronic items with renewable energy. The JOOS Orange is one way to cut our ties with non-renewables and start doing our part to charge “off-the-grid.”
Solar Components, the makers of the JOOS Orange are helping to make the switch even easier this holiday season by offering a special promotion on a bundle package consisting of the JOOS Orange, Reflector Kit, and Carrying Case. The bundle sells for $175 and is available exclusively at SolarJOOS.com.

Alta Devices has announced that its mobile power technology produces up to 5 times more power from indoor light than other commercially available solar technologies. Solar technologies such as dye-sensitized, organic, and amorphous silicon help to achieve these low light energy gathering goals, a goal Solar Components has had for the JOOS Orange since its inception.
Using a patented low-light circuit, the JOOS Orange is able to harvest low light solar energy where other solar chargers fall short. In live demonstrations, the company has shown how the device even charges when placed under a 100 watt light bulb using indoor light, and in several online videos the JOOS can be seen performing well and charging in gloomy, overcast days.
When considering to purchase a solar charger, these are the things you must keep in mind. Will the solar charger efficiently charge your devices or will it not be able to harvest enough solar energy to do so? The JOOS Orange has a proven track record, a patented low-light circuit, and has received the highest accolades from companies including WIRED Magazine, Outdoor Life, and more. In 2011, the JOOS Orange won the Consumer Electronics Association’s ‘Best in Show’ category, beating out products from other large technology companies.

SunEdison launches solar water pumps in India as more solar companies tailor their products to areas in need

SunEdison launches solar water pumps in India as more solar companies tailor their products to areas in need

solar-array-2Sun Edison recently launched a solar based water pump system in India to help farmers with irrigation in rural areas. The system is designed to increase crop yield by delivering reliable irrigation without dependence on expensive fuels or the rural area’s notoriously intermittent electrical power supply.
In the rural area of Tamil Nadu, for example, about half a million farmers are still awaiting power connection to irrigation pumps—an area SunEdison plans to focus on.
Living in the United States, we tend to take for granted the abundant sources of energy we have at our disposal, even though much of that energy still comes from non-renewable resources. When Solar Components designed the JOOS Orange personal solar charger, it did so to give hope to people in third world countries and to those without reliable power.
A single JOOS Orange can mean a world of difference for people in these countries where cell phones are the predominant means of communication, yet charging a cell phone requires a long walk or ride into the nearest town. People in these areas are now able to harness the power of the Sun to charge their cell phones without ever leaving their village.
You can help do your part to move off the grid by powering your own cell phone with a JOOS Orange. Over time, enough people switching to this renewable method of charging can reduce the strain on the grid and save money in the process, not to mention the convenience of being able to charge your phone wherever you are.
With 7.3 billion cell phones expected to be in operation by 2014, moving to a renewable means of charging them could save billions of dollars per year. In fact, to illustrate this point even further, according to LifeHacker magazine, the electricity used annually by the 170 million iPhone 5’s purchased in the next 12 months will be equivalent to powering all the homes in Cedar Rapids, Iowa for a year!
