In a recent report on Solar City teaming up with Tesla, Solar City will use Tesla’s batteries for energy storage. This fast-growing solar installer, Solar City, has found a solution to energy storage issue while reducing energy cost and demand cost. Called DemandLogic, it could allow businesses to use stored electricity in times of peak demand, reducing their usage at peak periods and the associated fees (called the demand charges). Below you will find a video of Solar City’s Lyndon Rive, discussing the transformative impact of Solar CIty:

 

Energy charges have risen rapidly (Source: EIA)-DemandLogic reduces your demand charges from day one. And because demand charges tend to rise, your savings increase over time (Source: http://www.solarcity.com/commercial/demandlogic/)

Lyndon Rive (cousin of Elon Musk, chairman of Solar City), Solar City’s chief executive, said that the systems would provide backup power and a working solar array during blackouts. Mr. Rive also added that he does not see the systems as a step toward independence from the grid, although storage is very important in maintaining grid stability as more customers continue to adopt solar.

Based on a $1.8 million grant in 2010 from the California Public Utilities Commission to study the possibilities of storing electricity from rooftop solar arrays in batteries, the product was developed. The company has also signed up approximately 300 of its residential customers for a pilot program using battery packs from Tesla (where Elon Musk, cousin of Lyndon Rive, is the chief executive of Tesla and chairman of the Solar City, as indicated in our post/video of Dec. 11, 2013). The company will offer its storage systems in parts of California, Connecticut, and Massachusetts.

“It’s not a no-brainer-you still have to have the  right combinations of rates and demand charges and the cost of the equipment.But if the systems are able to take advantage of a 30% federal tax credit, the economics would have broader appeal.” according to a senior research analyst at Navigant Research.

The new customers at Solar City systems signing 10-year service agreements are eligible for the credit. The Solar City systems are made to store about a third of the energy the solar array can produce. Mr. Rive guarantees that there would be reductions of demand charge, at about 20%. Part of the appeal is that the system allows businesses to continue operating at full capacity, rather than reducing power usage, as in traditional demand response program.

CSI, California Solar Initiative, Way To Go !!!

Share

Dear Friends, Readers/Viewers/Visitors,

(Please click onred linksbelow)

There is much hope and optimism for those involved with solar energy. I will be sharing with you a series of fantastic progress/news in solar energy world throughout our planet, starting with what’s been happening in California of USA.

According to CPUC (California Public Utilities Commission), the CSI (California Solar Initiative) has reached a milestone of 1 GW (gigawatt) of installed power.  The CSI has a goal of reaching 1,940 MW (megawatt) of installed power by the end of 2016 and a budget of $2.4 billion over 10 year period.  By the end of 2012, the CSI program had installed 1,066 MW in its general market and affordable housing photovoltaic programs, reaching  55% of its 1,940 MW goal, and an additional 332 MW (17% of its total goal) in pending projects.  The rebates are up 92% lower than they were at the start of the program in 2007, but participation in the program continues to increase.  Below is a video clip of the overview of how CPUC, through the CSI, will be helping existing businesses, public agencies, and homeowners to lower their energy costs, and to reduce reliance on fossil fuel-fed power plants and create a sustainable energy future by using solar technology:

Solar Energy Is An Industry on the Rise-President Obama Agrees!

Dear Friends and Readers,

This week, on Wednesday (March 21, 2012),  President Obama made his first stop at the Boulder City (about 40 miles southeast of Las Vegas), Nevada,  at Copper Mountain Solar 1 during his two-day energy tour, drawing attention to the ever expanding solar industry and to take on anti-solar lobby.  During President Obama’s speech at Boulder City, he reaffirmed his commitment to an “all the above” approach to domestic energy production and refer to the solar energy sector as an “industry on the rise”. President Obama’s speech at Copper Mountain Solar 1, below:


There is good reason why Copper Mountain Solar 1 was selected to be the first stop for President’s two day energy tour.  The Copper Mountain Solar Facility is a 48 megawatt (MW) solar photovoltaic power plant in Boulder City, Nevada. Sempra Generation built the plant from Jan., 2010 to Dec., 2010 at  a cost of about $141 million.  When the facility entered service, it was the largest photovoltaic plant in the U.S. (the previous record holder for the largest U.S. solar power plant was the 20 MW DeSoto PV plant in Arcadia, FL).  At its construction peak more than 350 workers were installing the 775,000 First Solar panels on the 450 acre site. An expansion of the facility by more than 200 MW was approved in 2010.  On August 4, 2011, Sempra announced a plan to expand the facility by 92 MW to be online in January of 2013 and another 58 MW to be added by 2015.  The power from Copper Mountain Solar and Sempra Generation’s adjacent 10 MW El Dorado Solar plant has been sold to Pacific Gas & Electric (PG&E) under separate 20 year power purchase agreement.

  • Solar 1 is the original 48 MW 1st phase with an expansion
  • Solar 2 is the under construction 150 MW phase 2
  • Solar 3 is a proposed 220 MW phase 3

When President Obama visited the Copper Mountain Solar 1 Facility in Nevada Wednesday, he had a first-hand look at the first large-scale facility equipped with solar forecasting devices called the sky imagers.  Sky imagers are essentially fish-eye lenses that capture a 360-degree view of the horizon and generate a 3-D model of the clouds being observed.  This device is connected to a sophisticated forecasting system that uses what it observes to predict solar output in 15-minute increments.  Sky imagers and their algorithms are the brain child of Jan Kleissl,

an environmental engineering professor at the Jacobs School of Engineering at UC San Diego.  Earlier this month Professor Kleissl’s research and solar forecasting at UC San Diego received $1.5 million grant from the California Public Utilities Commission (CPUC);he is the principal investigator on the grant with another professor of environmental engineering at the Jacobs School Carlos Coimbra This grant funds research to refine forecasting methods and work with San Diego Gas & Electric to help integrate solar power to the energy grid. In addition to the CPUC funding, the project is receiving matching funds from SDG&E (San Diego Gas & Electric), the National Renewable Energy Laboratory, the California Energy Commission and the Department of Energy. “As California continues to integrate higher amounts of solar energy into the grid, demonstration projects like these will maximize the value of solar energy by providing predictable generation profiles that grid operators can rely on,” said CPUC President Michael R. Peevey. The two researchers/scientists and their teams plan on developing comprehensive forecast models that predict solar power output based on how much sunlight can be found at a specific location and how it fluctuates.  Their sensor network now extends beyond San Diego to include many sites along the Pacific Rim, from Bellingham, Washington, to Oahu, Hawaii. This type of forecasting projects could reduce unpredictability of solar power and potentially generate significant savings for utility companies.

One thing to be certain, there are much work and opportunities in solar sector waiting to be discovered, for entrepreneurs, academic researchers and scientists, and homeowners and  renters alike.  As long as we continue to be optimistically active, there’s much needing to be done!
