5 year study by NAIT shows angle of panel is more significant than snowfall in Northern Alberta

Published

Study looks at impact of snow and angle of solar panels Old Man Winter takes a lot of flak in Alberta for everything from costly heating bills to frozen car batteries. But when it comes to the impact on solar panels, winter gets an unjustified bad rap.
A five-year study led by NAIT’s Alternative Energy Technology program found that snowfall on photovoltaic solar panels results in about a 3% energy loss. That’s significantly less than the 20% drain that industry had traditionally estimated despite a lack of data.
Tim Matthews, a technologist and one of the leads on the study, says the results will improve modelling used to estimate solar energy production that determines return on investment. Ultimately, that means a win for consumers.
NAIT launched the reference array snow study in 2012 with the City of Edmonton and Solar Energy Society of
Alberta. A system of 12 solar modules was installed atop the Shaw Theatre on Main Campus to not only measure the impact of snow on the system, but also how the tilt of each module affects energy production.
“The rule of thumb throughout industry was to design a system as if it had no snow and then wipe 20% of energy production off the slate – we’re going to lose 20% because we’re in Canada,” says Matthews. “Everybody was terrified of underestimating the impact of snow and latitude [on energy production].”
They found that the angle of the solar panels has a far greater impact on energy production than snowfall. Solar modules were fixed at six different angles – 14, 18, 27, 45, 53 and 90 degrees – which represent roof pitches commonly found on commercial buildings and homes. Six modules were cleared of snow every day, while the remaining six served as a control.
The least efficient was the module set at 90 degrees, like a wall-mount system, which saw a 24% loss in performance. The
module tilted to 53 degrees was most efficient, which confirmed an industry standard that solar systems are optimized when tilted to the equivalent of a city’s latitude.
The ideal angle for maximum production with snow accumulation was 45 degrees.
Matthews cautions that even five years worth of data is a small window when dealing with fluctuating variables such as
weather. But for a homeowner or business who already has historic data on their energy consumption, the tilt and snow impact clear up what had been a cloudy picture in predicting the cost-benefit of solar.
“Having this information raises the level of precision when it comes to engineering, design and production modelling,” says
Matthews. “A company that’s doing solar installation and design can go to a client and say, ‘This is precise. You can take this to the bank.’”
Crunching five years of data The work of crunching through all the data fell to students (and now grads of the class of ’18) Christian Brown and Jackson Belley as the basis of their final course project, or capstone.
That’s no mean feat considering energy performance data was collected from all 12 solar modules every five minutes every
day for five years – enough to fill 6,000 spreadsheet files.
“It was an insane amount of data,” says Brown. “That was not quite half, maybe the first third of the project. Months of work. It was a lot of learning.”
After five years of getting up at all hours to clear snow from the reference array – including Christmas – Matthews is glad
to be rid of that daily chore. For anyone who operates a solar system, he cautions that snow should only be cleared if it’s
safe to do so, such as on a flat commercial roof.
“Should you clean the ones on your [pitched] roof? Heck no,” he says. Nor does he recommend asking a contractor to
remove it. It’s just not worth it for the minimal gain in power efficiency from a snow-free solar system.
“Our recommendation is that it makes no sense. One hour of time from a professional or an apprentice is just not worth
it.”
Data was gradually exported by day, month, season and year, making it more digestible and user-friendly for industry,
government and institutions, but also the schools and not-for-profits, who are interested in the information.
The study’s interim findings are available online, while the students’ final report with datasets will be published on the
Alternative Energy Technology program page this fall. It’s expected to be a hot commodity. (Anyone can request the data now).
“The amount of requests that we get [for the data], it’s obvious people are interested and they want to know how does snow
affect solar modules,” says Belley.
Brown adds it’s a pretty cool feeling to work on a class assignment that has a major real-world impact. “The idea of solar won’t be as much of a gamble any more.”
Plans are also in the works to submit the findings for peer review and publication in a scientific journal.
After reading this report and remembering that both the Province of Alberta and the City of Red Deer are looking into a program that would pay for the program and be billed via your property taxes over 10 years.
The province and the city were very much forward thinking, I would offer and if snow loses only 3 % of power it does make more sense. Right?

Desperate Liberals move to stop MPs from calling Trudeau ‘corrupt’

Published on

From LifeSiteNews

By Clare Marie Merkowsky

Conservative MP Corey Tochor argued the term “corrupt” is an accurate description of Trudeau and his government.   

“If you ask the Ethics Commissioner about all of the infractions that the Prime Minister has been charged and convicted with on corruption, you will find the truth to be that this is a corrupt government and Prime Minister”

Liberals are pushing for the word “corrupt” to be banned in Parliament amid ongoing ethics scandals within the Trudeau government.  

On April 19, Liberal Member of Parliament (MP) Mark Gerretsen moved to prohibit MPs from referring to Prime Minister Justin Trudeau and his government as “corrupt,” arguing it is disrespectful towards the Liberal government.  

“My point is that, today, during question period, the member for Regina—Wascana referred to the Prime Minister as ‘corrupt’ and to the government as ‘corrupt,’” he told the House of Commons.  

“Although he did it today, it has been done a number of times in the House,” he continued. “I would say that terminology specifically goes against Standing Order 18.” 

The House of Commons’ Standing Order 18 regulates speech within the House to ensure that MPs do not use disrespectful or offensive language.  

“No member shall speak disrespectfully of the Sovereign, nor of any of the royal family, nor of the Governor General or the person administering the Government of Canada; nor use offensive words against either House, or against any member thereof,” it states. “No member may reflect upon any vote of the House, except for the purpose of moving that such vote be rescinded.”  

“I would encourage the Chair, during this time of reflection over that week that he indicated he was going to do that, to consider my comment on this and to weigh into whether or not this is actually,” Gerretsen added before being interrupted by Conservative MPs calling for a debate. 

However, Gerretsen refused to debate his suggestion, instead pushing for Conservatives to be censored. Gerretsen’s recommendation was supported by Bloc Quebecois MP Martin Champoux.  

“I would like to build on what my colleague just said,” Champoux said. “I actually raised a point of order about this yesterday with the Speaker, who was in the chair at the time, to ask him to once again set out strict rules and clear guidelines for members to follow.” 

“That would help us to better understand how far we can go,” he argued. “Right now and for the past few months, there has been a lack of consistency in the way freedom of expression is interpreted in the House and in the way measures are applied when members cross the line or do not follow the guidelines, which, again, are not exactly clear.” 

However, Conservative MP Corey Tochor argued the term “corrupt” is an accurate description of Trudeau and his government.   

“If you ask the Ethics Commissioner about all of the infractions that the Prime Minister has been charged and convicted with on corruption, you will find the truth to be that this is a corrupt government and Prime Minister,” he declared.  

Indeed, between the ArriveCAN app scandal, alleged Chinese election meddling and the SNC-Lavalin affair, Canadian MPs seem well within their rights to call, or at least remain concerned, that Trudeau and his government are “corrupt.” 

So, why are Liberals moving to have the term banned? 

It appears Trudeau and his government prefer Canadians remain unaware of past and ongoing corruption scandals, preferring to silence those who remain unconvinced by Liberal Party propaganda.  

Unfortunately, it seems this trend is only going to continue.

As LifeSiteNews recently reported, law professor Dr. Michael Geist warned that the Trudeau government is “ready” to “gaslight” opponents of Bill C-63, a proposed law that could lead to jail time for vaguely defined online “hate speech” infractions.  

While the banning of the word “corrupt” in Parliament may not yet be implemented, who is to say that if Bill C-63 is passed that the Trudeau government won’t decide to consider such accusations of corruption as meeting the definition of online “hate speech.”

Indeed, perhaps the Liberals’ move to ban the word “corrupt” should be considered a sign that they know they’ve lost the public’s trust and are acutely aware silencing opposition is their only option.

In fact, it would appear that Trudeau’s only response to dismal polling figures with respect to his scandal-plagued government’s popularity is to double down on censorship, rather than consider why citizens feel the way they do.

As the late U.S. President Harry S. Truman warned: “Once a government is committed to the principle of silencing the voice of opposition, it has only one way to go, and that is down the path of increasingly repressive measures, until it becomes a source of terror to all its citizens and creates a country where everyone lives in fear.”

Col. Douglas Macgregor: US is ‘facing disaster’ as it funds overseas wars while bankrupt

Published on

From LifeSiteNews

By Frank Wright

“We have a government that consists of 525 lobbyists – and that’s why we have the policies we have.”

Following the news that the U.S. Congress has finally approved $95 billion in “aid” to Ukraine, Israel, and Taiwan, retired Colonel Douglas Macgregor has returned to ask the difficult question – why is the U.S. funding wars when it is bankrupt?

In an April 21 video interview with U.K. member of Parliament George Galloway, Macgregor gave a blunt and shocking answer.

“We have a government that consists of 525 lobbyists – and that’s why we have the policies we have.”

His full remarks open the video with a searing assessment of the level of corruption in the United States government:

I would currently say that we have a government that consists of 525 lobbyists as opposed to representatives – people who are all busy lobbying for money with which they can line their pockets. Now some of them are just ignorant … some are destructive … but all of them, I’m afraid, with very few exceptions, are bought men.

The U.S. is facing disaster, says Macgregor. With the national debt at over $34 trillion, and the total U.S. debt including households and corporations at almost $100 trillion, the economic situation is just one dimension of the disaster of debt and corruption he says has financed the capture of the political system.

His startling description of a blackmailed captive political class would account for why such an indebted nation is so keen to hand over so much money to fund foreign wars. After six months of wrangling, the House voted to approve $95 billion in lethal and non-lethal aid. $60 billion goes to Ukraine, $26 billion to Israel, and the rest is allotted to future flashpoint Taiwan.

With Macgregor and others saying there is no public support for these measures, how is this level of spending possible?

Washington, D.C. ‘a large Epstein Island’

Epstein Island, as you know, is the place where people were set up with underage girls, and it looks like enough of them have been involved in it that they’re all they’re all blackmailed.

Macgregor notes he is not the only one to reach this conclusion:

That was Tucker Carlson’s most recent allegation – that people on the Hill who lead sadly bizarre lives are blackmailed.

Macgregor is referring to this April 3 interview between Tucker Carlson and Rep. Marjorie Taylor Greene, in which Carlson asks why Speaker Mike Johnson seems “completely disconnected from what we want.” The video below shows a brief excerpt from the interview.

Carlson observed the striking difference between Mike Johnson’s principles and his actions:

Mike Johnson has made a complete departure of who he is and what he stands for – and to the point where people are literally asking, ‘Is he blackmailed?’

Carlson also noted that “70 percent of Americans … and the majority of Republicans do not support funding Ukraine.”

Macgregor’s Epstein Island thesis may explain the mystifying personality change in Mike Johnson. Macgregor went on to conclude:

If that’s the case [the elected representatives] could be compelled to vote in whatever direction the very wealthy and powerful oligarchs in the United States [desire].

We are used to hearing “mogul,” “scion,” or even “philanthropist” to describe the billionaires in the West with state-level influence. This is the reason for Macgregor’s use of the term “oligarch” – usually reserved for the same class of people in enemy nations.

I say oligarch because someone who’s a billionaire hedge fund manager can just as easily buy policy outcomes as an oligarch in Russia or Ukraine.

Macgregor sees this sponsorship of politics as the root of the crisis in America.

I think that’s our biggest problem.  The only way that it will end is with some form of financial collapse – which many of us think is going to happen.

Macgregor points out that the vaunted GDP – the Gross Domestic Product by which the size and health of the economy is measured – “is an illusion.”

“We are currently living on income that is close to 50% of government income,” he said, pointing out that the U.S. is living not only on borrowed money, but also on borrowed time.

“This can’t go on forever. We just don’t know when it’s going to happen but something is going to come along and tip us over,” he warned. “When that happens there will be an opportunity to clean house and hopefully start over – and put an end to this unnecessary overseas empire.”

The domestic crisis is largely ignored, said Macgregor, by a political elite which “acts as if it is still 1991.”

This crisis, which includes that on the U.S. border, and a breakdown in law and order so severe that Elon Musk called for crime to be made illegal again, is one which sees no explanation at all as to why actions are taken to make everything worse.

As Carlson pointed out, no one in power ever really explains why they are taking these decisions, as their policies fuel an expanding global and domestic catastrophe.

Since Joe Biden became president, the U.S. government has spent hundreds of billions of dollars fighting an undeclared war against Russia.

No one in all of that time has explained really the purpose of this war, why it would benefit the United States or the world.

Yet the war in Ukraine is not the only one being funded. The genocide in Gaza simply could not continue without a constant supply of U.S. arms – and money. Carlson added that “ethnic and religious” reasons play a part, but that even these fall short of a convincing reason.

Clearly, at least some policy makers are motivated by ethnic and religious hatred. That’s probably part of the real reason. But officially, no one has told us why we are doing this.

Ukraine war – and NATO – lost?

Regardless of the dark motives for the wars, Macgregor considers the one in Ukraine lost, and the money will make no difference to Russia’s post-war plans. He thinks this defeat will break the NATO alliance, with the Europeans breaking away to forge a different future.

I think even the Europeans, who were even more misguided and utterly confused than much of the American population, are going to realize that there’s no future in this relationship between us and them.

He says the European allies will see “that they too have to save themselves – that they’ll have to chart a new destiny for themselves. So I think that’ll be the end of NATO.”

With a dissolving military alliance abroad, Macgregor turned to the question of Israel. Why has the Biden administration changed its initial tune of “unconditional support” for Benjamin Netanyahu?

Until recently it was unconditional support for Israel. I think the reality has begun to set in with some of the senior people behind the scenes that are instructing Biden and controlling the Congress, that there’s a very real potential for a major war that would draw in Russia and China – and other countries – and could frankly destroy Israel and fatally harm us.

So now I think there’s a sense of helplessness, and that helplessness leads to pleas for cooperation with Mr. Netanyahu.

Macgregor warns that though it is “a good thing” that Netanyahu “did not get his war with Iran,” he counsels that this “doesn’t end the probability of a future war with Iran,” as Netanyahu “continues to enjoy unconditional support [from the U.S. government] for this program of mass expulsion and murder in Gaza.”

‘You’ve got to save yourselves’

With politics controlled by a “donor class” that effectively dictates spending, Macgregor warns against the desperate belief in some national savior.

“I’m one of these people that really dislikes the notion that any one candidate is going to rescue us,” he said, addressing the idea that some “Napoleon” may emerge to save America.

I keep telling people: stop talking about Donald Trump or RFK Jr. or anybody else saving us.

You’ve got to save yourselves.

He thinks this message is getting through – “but we’ve got a long way to go”. Most Americans are “too busy trying to put food on the table,” he adds, with others sadly taking in “the usual nonsense from the mainstream media.”

He thinks perhaps a third of Americans have awoken to the gravity of the situation:

Right now perhaps a third fully understand what’s happening in the country and the dangers abroad- but that’s about it.

Macgregor, a retired US Army colonel, makes an impressive summary of nuclear capabilities in the Middle East, mentioning the widely held assessment of Iran as a “threshold” nation. His appraisal is that the dangers of war are misunderstood, or even ignored, by a political management that is out of its depth and disconnected from contemporary reality.

Speaking of President Biden, he said “we’re dealing with someone now who is eminently incapable of coping with the reality of what you and I have been discussing,” before going on to note that those behind the president are less incapacitated, but deluded.

However, there are others behind Biden who are not total fools. They … are simply amateurs.

He says their assessment is of a reality that no longer exists – and whose God-given rights and way of life their policies are destroying.

They’ve been playing at everything as though America is still what it was in 1991: they are ignoring the open borders which they have deliberately created to dilute our population and essentially erase the American culture and national identity.

Macgregor says they are responsible for the chaos inside what were America’s borders.

They are the ones who are releasing criminals onto the street by destroying the justice system. They’ve ruined the armed forces in terms of morale and capability – it’s at an all-time low.

This toxic combination makes for a bleak prognosis from the retired colonel.

So you add that to the equation and the only thing I can see ahead for the United States right now is total disaster.

Yet Macgregor does not simply pronounce doom. He is trying to mobilize Americans in defense of their nation under God.

Macgregor is the CEO of Our Country, Our Choice – an organization which stresses the centrality of God, family, and country to the American success story whose passing he laments in detail.

Its founder, RJ, describes himself as a “devoted Christian” appalled at the theft of liberties under lockdown and shocked into action by the chaos flowing from the Biden administration.

“We’re driven by an unwavering commitment to protect what matters most: our faith, our loved ones, and the land we call home,” says the founding father-of-four, describing why he created OCOC in 2021 himself. “As I witnessed America’s trajectory under the Biden administration, it became increasingly chaotic and disheartening.”

He tells how he was moved to do so:

I reached a breaking point, realizing that the responsibility of reclaiming our country and defeating the deep state ultimately rests with us, the American people. No one else will step up. So, I made a bold decision, risking everything I had, and founded Our Country Our Choice.

His message to the American people is that they can take back their country and their politics from a class determined to destroy them.

It is one which Macgregor is determined to spread. There is hope amidst this desolation, says Macgregor, who believes that it lies with the American people themselves, and the defense of their God-given rights.
