Historical Advances In Producing Electricity From The Sun

When politicians start talking about renewable energy, you know we have problems. Solar energy is a significant renewable energy and here is an overview of how the technology has developed.

First Practical Solar Cell
Solar electricity is simply energy produced by harnessing the sun. It comes in many forms including electricity production through panels, home heating through passive systems and mobile packets for powering devices like laptops and RVs to mention only a few platforms.

Historically, sunlight has been used by mankind to produce heat ever since we first built structures. Without electricity, mankind soon learned to orient structures to capture the heat of the sun during the day and store it in ceramic or mud materials much like a blacktop parking lot will radiate heat after the sun has gone down. Early Greek structures show a particular use of this solar strategy as do Egyptian structures.

The production of electricity using sunlight is a much more recent phenomena. In 1901, Nicolas Tesla was the first person to receive a patent related to solar electricity, but he called it radiant heating. He sought a patent for a machine to capture the radiant heat, but nothing much came of the invention.

In 1904, some unknown physicist named Albert Einstein published a paper on the potential electricity production from sunlight. In 1913, William Coblentz received the first patent for a solar cell, but he could never make it work. In 1916, Robert Millikan was the first to produce electricity with the cell. For the next forty years or so, nobody made much progress because the cells were highly inefficient at converting sunlight to energy.

In the 1950s, Bell Labs got involved with NASA. Bell was charged with coming up with a solar platform to power spacecraft once they were in orbit. The solar industry would never be the same.

Gerald L. Pearson, Daryl M. Chapin, and Calvin S. Fuller started researching different areas related to solar, but not active parts of the NASA project. By luck, they meet and exchanged ideas. While their individual projects were failures, their combined efforts produce a much more efficient cell using crystallized silicon to convert sunlight into electricity. The efficiency rate of the cells was roughly 6 percent, a marked improvement over previous technology. In 1958, NASA launched the Vanguard Spacecraft, which was powered by solar panels.

In the following years, solar technology grew in leaps and bounds. Solar panels today are roughly 15 percent efficient, but also much smaller than they use to be. More importantly, companies are abandoning the panel platform and coming out with amazing new products. The first are shingles that look exactly like regular roof shingles and perform as such. Nanotechnology is also offering amazing possibilities with quantum dots, which are essentially solar panels on the quantum level. Eventually, these dots will be incorporated in things such as paint. Yes, the paint on the walls of buildings and homes will eventually also produce all the electricity needed for the structures.

Man has used the power of the sun for heat for a very long time. Only now, however, are we starting to master the technology to turn it into large amounts of free electricity.

Solar Panels May Have Ultimately Arrived At Economic Efficiency

The last example of this specific phenomenon was apparent was in the early 70’s, when there was a crude oil trade embargo and hence, no gasoline. Substitute energies began to pop up here and there with many people jumping on the band wagon.

But, gasoline soon returned in plentiful supplies and unconventional energy sources fell beneath the average consumers radar screen again. Now, in 2017, the common consumer is seeing petrol prices move higher and found a realization that global warming will be affecting finances soon. Substitute energy is back in the sentiments of the ordinary consumer and, maybe, this time for good.

Where did solar go?

Solar power for the home was a big seller during the energy crisis of the 70’s. Many houses found tri-pods of solar panels on their roofs gathering what power they could. These units were found mostly in environmentally sensitive Arizona, but soon they were found across the World. Unfortunately, the solar power cell of the 70’s just wasn’t all that cost-effective and cost quite a bit to put in and maintain. As fossil fuel returned to the marketplace there was diminutive need for solar cells in a time of flagrant consumption. But the idea of solar energy was a good one and many trailblazers understood that it was a good idea that had yet to find its time. Solar panels never went away; they just slid back into the laboratory to await solar panel 2.0.

Solar is back and ready

Today’s solar panel is not your father’s solar panel. Depending upon which type of energy you care to generate, electricity or hot water, today’s solar panel has come a very long way in the form of photovoltaic’s and will go further still. These cells, when combined into panel form, turn the suns rays (so-to-speak) right into power ready for use. They have also become exceedingly efficient, more environmentally sound and less expensive. Today’s solar panel will sit almost anywhere and is quickly finding itself being turned into a panel the thickness of a nano particle. Solar power technology is running at extremely fast pace and driving costs down to an affordable level.

Who’s using the panels?

As mentioned, it takes a change in the purse strings to see a marked change in a consumer’s behavior. With a technology and paradigm shift on the order of solar panels it requires a solid leap forward in panel efficiency, costs of panels , associated elements and an increase in existing costs of fuel. When these factors reach critical mass solar panels start to show up, not at the consumer level, but at the corporate and industrial level. This is simply because business moves its money where the costs-over time-are less. This is just good business. Solar panels are now, as in this past two years, become more cost effective for industry to use then to not use them over time.

Why solar panels now?

Solar panels are now being used primarily because fuel costs are just too high to ignore in favor of a new technology that is worth checking out. Companies have available empty roof space and the choice of trying something on a larger scale to see if it works versus continuing to pay higher fuel bills and environmental costs. The whole concept is extremely self serving. There is no environmental consideration involved. If the company doesn’t use solar panels they have to pay fuel costs and air clean-up expenses along with variable fuel charges. They try out the solar panels and see if they work now. If they do, the company can; commit to a full solar panel program with even more efficient solar panels, significantly reduce fuel costs and almost eliminate air cleaning needs along the way. There is little environmental about it. It’s just good business. After industry gets rolling, solar panel costs will drop like a stone and the consumer will jump on board because…it’s just good business.

Campbell Soup headquarters to add 4.4-MW of solar

Campbell Soup Company, in partnership with BNB Renewable Energy Holdings (BNB), SunPower and ORIX USA  broke ground today on a 4.4-MW solar power project at the company’s world headquarters in Camden, New Jersey.

Scheduled to come online in fall 2017, the system will provide energy to Campbell through a 20-year power purchase agreement and generate more than 5 million kilowatt hours of electricity per year. Upon completion, the solar array will become the largest in the city of Camden.

The project, developed by BNB, will feature SunPower’s innovative rooftop, carport and ground-mount solar solutions, which are designed to optimize power production for commercial customers like Campbell.

At Campbell’s 38-acre world headquarters campus, 2.7 MW will be installed on the rooftops of existing structures and on new solar canopies that will be erected in the parking lots. An additional 1.7 MW will be installed on an adjacent 4.5-acre remediated brownfield that BNB purchased specifically for the project, making use of otherwise unusable land and increasing the capacity of the system.

Under the 20-year PPA, Campbell will buy electricity generated by the solar project at a predetermined rate. The fixed PPA rate, which is currently lower than the cost of traditional electricity for Campbell, provides the company with long-term visibility for this portion of its electricity costs.

The system in Camden will be the third solar project that BNB has developed for Campbell, following the 9.8-MW system at Campbell’s facility in Napoleon, Ohio, and the 10-MW system at Campbell’s Pepperidge Farm bakery in Bloomfield, Conn. Both of those projects also use SunPower’s high-efficiency solar panels.

“We’re excited to partner once again with BNB and SunPower to add a third solar array to Campbell’s U.S. footprint,” said Jim Prunesti, vice president, global engineering, Campbell. “This project contributes clean energy to the local grid and demonstrates to our community the viability of renewable energy sources, all while supporting Campbell’s sustainability strategy to deliver long-term value to our business and neighborhoods.”

BNB and ORIX USA, a diversified financial company with a strong commitment to renewables, will jointly own the project. The term debt is being financed through PSE&G’s Solar Loan Program.

“Bringing a cost-saving solar system to Campbell’s World Headquarters marks a great moment, and we see a bright future for other Fortune 500 companies who follow Campbell’s lead and turn to renewable energy to stabilize energy costs and reap rewards from the sun,” said Matthew Baird, managing partner of BNB. “We are most proud of our collaborative work with Campbell, SunPower, ORIX and PSE&G to make this project a reality.”

The project will also feature five electric vehicle-charging stations, provided by PSE&G via its EV Workplace Charging Program, for use by Campbell employees.

“It’s an honor that Campbell and BNB have chosen SunPower once again as a solar partner for this project,” said Nam Nguyen, SunPower executive vice president. “We look forward to delivering the highest quality experience through our innovative solutions.”

Japan’s solar reforms cast shadow on renewable energy

Changes in April to legislation concerning Japan’s feed-in tariff scheme, which lets renewable energy producers sell their power to local utilities at government-set prices, stripped power-sales licenses from as many as 460,000 entities that have not …#renewableenergy #energy #renewables #solar #solarpower #greenenergy
