84 Million Homes on Zillow Now Show Solar Potential of the Home

Sun Number and Wave Solar announced today that 84 million homes on Zillow now include a Sun Number score, which shows the potential solar generation of the home. This information helps millions of homeowners understand their options for going solar.

“Home sellers and buyers that have not had Sun Number scores previously have been contacting us asking how they can get a Sun Number score for their home,” said David Herrmann CEO of Sun Number. “The expansion of Sun Number scores to 84 million residential buildings on Zillow means many of those homeowners, sellers, and buyers have a simple way to access this useful information.”

Sun Number uses multiple datasets to analyze an individual home’s solar potential, taking into account the angle of the roof, the direction the home is facing, the solar radiation potential of the roof, and local electricity rates. Sun Number’s algorithm ultimately assigns a score to the home between 0 and 100, estimating how much the homeowner would stand to benefit if they went solar.

“This data is important for the millions of people participating in the U.S. market shift towards solar energy,” said Colin James Walsh, CEO of Wave Solar. “With the Sun Number scores on America’s most popular real estate site, homeowners will have more data to make an informed decision, and solar installers will see even more interest in their product.”

The Sun Number score is included on 84 million homes on Zillow under the “Utilities, Green Energy” section of the page. Sun Number scores were first added to millions of homes on Zillow in August of 2016 and the 84 million homes on Zillow are live now, including a majority of homes for the first time.

“We are very proud of our proprietary scoring system, which was developed as part of the Department of Energy’s SunShot initiative,” added Herrmann, “By bringing these different solar-relevant datasets together into one easy-to-understand score, we allow homeowners to see if they should be exploring solar as an option for their home.”

How to Find SunNumber on a Zillow listing

1. Go to a home listing on Zillow.com
2. Click “See More Facts and Features”
3. If listing is one of 84 million, SunNumber will be listed under “Utilities – Green Energy”

Kingspan Solar Project to Save Town Over $40,000 a Year for 20 Years

Kingspan Energy, with financing from the Connecticut Green Bank, has commissioned nearly one Megawatt of rooftop solar at Carmen Arace Middle and Intermediate School in Bloomfield, Conn. completing its largest project in North America to date.

Kingspan installed 2,926 Hyundai panels on the roof of the school. The building covers approximately 170,000 square feet and is the largest energy consumer in the school district. Carmen Arace houses two schools under one roof, serving more than 500 students in grades 5-8.

The solar system will offset more than 80 percent of the school’s electrical use. The power purchase agreement (PPA) will provide a discount of more than 60 percent over the current electric rate and the PPA has a fixed 25-year term. Wayne Casper, Director of Facilities at Bloomfield Public Schools, said the project is expected to save more than $40,000 annually in energy costs and $1.1 million over 25 years. Casper said the district currently spends nearly $250,000 annually in energy costs at Carmen Arace.

Alberta Residential and Commercial Solar Program

On June 21, 2017 Energy Efficiency Alberta has announced a new Residential and Commercial Solar Program aiming to achieve a goal of 10,000 new rooftop solar installations by 2020.

This program is not Alberta’s first incentive program for solar, although it is the most ambitious one to date, offering significant incentives to residential, commercial, and non-profit customers in the province. It is based on earlier extremely popular solar programs for municipal and on-farm solar projects.

If you own a home in Alberta and are looking to install solar panels, you can now receive 30% off your solar panels system cost up to a maximum of $10’000. The $0.75/watt solar rebate is based on the total installed capacity of your project.

Ground-mount or Rooftop residential solar panels systems are limited to 15kWp DC in size, which equals, for example, to 60 panels of 250 Watts each.

At the same time if you are a business or a non-profit organization in Alberta, your solar panels rebate can reach 25% or $500’000, whichever is greater. Solar farms and arrays are limited to 5 MW in size. Rebate value is set at $0.75/watt as well.

In order to qualify for the program, residential solar system must be energized within 180 days and commercial and non-profit within 365 days of the Part I approval date. After completing installation and connecting your solar panels system, you would have to submit your eligible expenses to Energy Efficiency Alberta.  Approval and allocation of funds will occur on a first-come, first-serve basis.

“The Government of Alberta is positioning the province for the diversification of its energy future by exploring another one of its abundant energy sources – the sun. More Albertan households and small businesses will now be empowered to go solar, strengthening local economies and creating jobs. The government has delivered on their word, and the Canadian solar industry is ready to deliver in return,” says John Gorman, president and CEO of the Canadian Solar Industries Association.

Commercial Solar Panels Installation in Alberta

According to David Dodge, the chairman of EEA, “The Prairies have the best solar resources in Canada, and there are a lot of potential investment opportunities. This is the first of several programs that will help create jobs and diversify Alberta’s energy economy into clean sources of energy.”

Energy Efficiency Alberta estimates that the new rebate program will:

  • Support the creation of 900 jobs in Alberta’s solar sector
  • Cut solar installation costs by up to 30 per cent for residences
  • Cut solar installation costs by up to 25 per cent for businesses and non-profits
  • Reduce greenhouse gas emissions in the province by about half a million tonnes—the equivalent of taking 100,000 passenger vehicles off the road

Residential Solar Panels Installation

Rob Harlan, Executive Director, Solar Energy Society of Alberta, applauded the new measure. “Albertans are ready to go solar, with growing demand, a world-class solar resource and an eager and capable solar industry. A sustained government push has been the missing piece for creating local jobs and clean energy in our province.”

Air Pollution Casts Shadow Over Solar Energy Production

Duke engineering professor Michael Bergin (left) stands with Indian Institute of Technology-Gandhinagar colleague Chinmay Ghoroi (right) next to that university’s extremely dusty solar panel array.

Global solar energy production is taking a major hit due to air pollution and dust.

According to a new study, airborne particles and their accumulation on solar cells are cutting energy output by more than 25 percent in certain parts of the world. The regions hardest hit are also those investing the most in solar energy installations: China, India and the Arabian Peninsula.

The study appears online June 23 in Environmental Science & Technology Letters.

Off-Grid Solar Charging Keeps College Students Connected

Solar Charging – Anywhere

Dotted around college campuses throughout the U.S. are students sitting at outdoor tables that include a solar panel canopy. While doing classwork, they can access the internet, recharge their phones and computers and socialize with other students.

These are attractive, extremely durable tables, forged from structural steel with a sleek architectural look. Placed in highly trafficked areas without access to electrical outlets, they make a bold, green statement about a campus or a corporate facility. The tables fit well into the work and lifestyle choices of people who like to get out of the classroom or office and work outside, in natural light and good weather.
