Sungrow has supplied the 902 MW Vista Alegre project with its 1+X Modular Inverter solutions. 

The project, which the company calls one of the largest PV projects in the Americas, is located in Minas Gerais, Brazil, and will deploy mainly utility-scale solar under a 21-year PPA. It is set to be grid-connected next year.

Sungrow says its inverter for this project combines central and string inverters, featuring a 1.1 MW single unit as the minimum. The maximum capacity can be expanded to 8.8 MW by combining units together, bringing a more flexible design for different block sizes. Each module is designed with an independent MPPT.

Sungrow will supply a solution for the project that includes the inverters, power transformers, medium voltage switchgears and auxiliary systems. This project will be supplied with 75 units of 8.8 MW and 18 units of 6.6 MW inverters, in addition to all services of cold and hot commissioning and O&M training.

“This is one of the Americas’ largest solar projects located in Brazil, a country with vast potential for further solar power generation, which offers energy security and independence and reduces carbon emissions in this vital decade for the clean energy transition,” says Ada Li, vice president of Sungrow Americas. “Sungrow is committed to providing clean power for all and we look forward to progressing with this project stream.”

Homeschooling

Published

Decent and intelligent people respect the rights of parents to homeschool their children, but there are two reasons for concern: a) socialization, failure to expose children to their peers, so that they may make friends and come to understand the norms of society, and b) the quality of the education itself.

Almost all homeschooling in the United States is conducted on the basis of a radical rightwing viewpoint, normally a blend of evangelical Christianity and Trumpism.

The Positive Effects We’ve Had on Others Are Profound, Whether We Know It or Not

There’s a theory that most people underestimate the positive effects they’ve had on other people.

Yes, that’s the theme of “It’s a Wonderful Life,” but it’s also the core of the 1995 film “Mr. Holland’s Opus,” in which a music teacher who deemed that his life had been a failure because he never completed writing a great symphony, is gently and beautifully corrected. Please see below.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

I tell this story because the claim made at the upper left is essentially identical.  You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this.  We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.
