Tesla Restores Power to Children's Hospital in Puerto Rico in 'First of Many' Solar + Storage Projects

October 25, 2017 by Lorraine Chow

SNIPPET:

Earlier this month, Tesla CEO Elon Musk offered to help restore Puerto Rico's hurricane-wrecked power grid with the company's batteries and solar panels. Gov. Ricardo Rosselló responded positively.

Making good on the promise, Tesla has switched on a combination of its solar panels and Powerpack commercial energy storage batteries for Hospital del Niño, a children's hospital in San Juan. The Puerto Rican capital was hit especially hard by Hurricane Maria.

According to a company tweet sent yesterday, this is the "first of many solar + storage" projects.

Yingli Solar Panels Will Help Low Income Villages In China 

November 6th, 2017 by Steve Hanley

SNIPPET:

People assume that the booming economy in China over the past 30 years has made all Chinese citizens wealthy. Nothing could be further from the truth. In Zhangbei County, just 150 miles northwest of Beijing, there are 128 low income villages where residents struggle to get by. Now all those villages are in line to benefit from a 300 kilowatt solar power plant. The project will use 140,000 solar panels supplied by Yingli. They will be installed on ground mounted systems with sun tracking capability to maximize power output.

Solar: an Unstoppable Force

November 20, 2017

From the steeply gabled roofs of Tudors to the flat roofs on turn-of-the-century brownstones, to a sea of warehouses, the Chicagoland market is diverse and demanding. See how Solar Service Inc. chooses products and tools that are up to the challenge.

As Mexican Solar Auction Prices Scrape Bottom, Will Quality be Threatened?


November 27, 2017

By Charles Thurston Freelance Writer
         
The latest round of solar auctions in Mexico yielded an unheard-of average price of US $20.57 per MW, including a $17.70 per MW bid by Enel, a coup for the government. However, as developers and EPCs scramble to under-bid one another in the current market, the price eventually will erode the quality that is deliverable. Indeed, this auction round may have hit the crossing point suggests Enrique Roig, the director of the Solar Steel business of Gonvarri Steel Services, based in Madrid.

"It is difficult to understand how bid prices can go lower. It can jeopardize quality and longevity. Low prices versus quality is at crossing point," Roig said.

Gonvarri is supplying the single-axis trackers for the 350-MW Solem solar project in in the municipality of El Llano, Aguascalientes state, with a planned startup of unit one in September 2018 and unit two in June 2019. The plant is being built on two sides of a road, using over 1 million solar panels and Gonvarri’s latest TracSmarT design.

The project was awarded to London-based Cubico Sustainable Investments, in Mexico’s second long-term electricity auction in September 2016. Cubico, which is developing the project with minority partner, Alten Renewable Energy, claimed at the time that Solem would be the largest solar plant to be built in Latin America.

Gonvarri will be supplying the steel for Solem from its Tijuana factory, helping to reduce the final cost of the project, since steel represents about half of the cost of a tracker. “We are still making money with Solem, but to meet the price in round three we would need to squeeze internal costs again,” said Roig. “When you squeeze price, the impact needs to be shared among the UPCs, the local contractors and the manufacturers,” he said.

“With these prices, what you will see over the next five years among small tracker manufacturers will be a strategic sharing of risk capital and cash flow,” Roig suggested. “Otherwise only large developers can bid.”

Financiers for the Solem project were a virtual who’s who of multilateral lenders, including: the Inter-American Investment Corporation, acting on behalf of the Inter-American Development Bank; the Canadian Climate Fund for the Private Sector in the Americas; the China Co-Financing Fund for Latin America & the Caribbean; the International Finance Corp., Bancomext, Banobras and Mitsubishi UFJ Financial Group.

Half of Cubico’s equity is owned by the Ontario Teacher’s Pension Plan and the Public Sector Pension Investment Board fund. Cubico’s global renewables portfolio spans eight countries with an installed gross capacity of approximately 2.5 GW.

The TracSmarT design incorporates 60 panels per tracker, configured with a three module by 20 module row, which reduces the number of plies and motors per panel, compared with leading centralized tracker designs.

Gonvarri is a subsidiary of the industrial group ACEK, which has more than 140 industrial plants in 25 countries, with a presence in the European Union, Mercosur and NAFTA countries.

Looking for New Solar Markets? Think Water.

December 7, 2017

By Jennifer Runyon Chief Editor

SNIPPET:

Yung Wong, engineering manager with WorldWater and Solar Technologies explained that when disaster hits, the first thing that the Red Cross and the military do is fly in water bottles. He said that the cost to transport water comes out to about $1.85 per gallon whereas his company can provide drinking water for just a few cents per gallon though a mobile self-sustaining system that purifies water from any source. The system includes 3 kW of solar PV capacity and a 31-kWh deep cycle battery bank and transports as a 7-foot cube. 

Wong said Puerto Rico has about 11 systems in place right now. Systems are also in place in Iraq, Haiti, and Darfur.
