23 years of green

Many of our customers get this question from their environmentally conscientious friends: How much energy does it take to manufacture solar panels compared to how much energy they produce?  Good question!

The Institute of Science in Society has an answer: The Institute’s life cycle analysis shows that the energy payback for polycrystalline panels (which is what Sungevity uses) is 2.2 years.  In other words, after 2.2 years, the power generated by the panels exceeds the power used to manufacture them. The panels have a lifespan of at least 25 years which means 23 years of clean, green energy on your roof. That’s a fantastic energy payback by any standard and makes us doubly confident that solar is the single best way to go green.

 

Neighbor see, neighbor do

There goes the neighborhood

At Sungevity, we’ve known for a long time that the best way to spread solar is neighbor-to-neighbor and friend-to-friend. Customers in our Sunshine Network are solar evangelists who often get their friends and family to go solar too.

So we were happy but not surprised to see the Stanford study that found that for every 1% increase in the number of solar homes in a neighborhood, the length of time before the next solar installation decreases by 1%. Now that might sound trivial to you (if, like me, your math skills topped out in 5th grade). But there’s an exponential effect at play here that causes solar adoption to snowball. John Farrell from the Institute for Local Self-Reliance explains it like this:

If you start with a neighborhood with 25 solar installations, where it was 100 days between the 24th and 25th installation, this peer pressure effect will reduce the time between installations to just 10 days by the 250th [photovoltaic] project.

The graph below shows how this plays out:

We’d like to thank our customers and all solar homeowners for helping form this giant (and paradoxical) solar snowball!  Keep it up and solar homes will some day soon become the new normal.

Sungevity and Sierra Club announce partnership from roof of Oakland home

Sungevity and Sierra Club launched the Sierra Club Solar Home Campaign today, and we couldn’t be more exciting about our partnership with this venerable grassroots environmental organization.  Read our joint press release below:

Sungevity and Sierra Club Join Forces to Accelerate Rooftop Solar in Northern California

OAKLAND, Calif.—Today, Sierra Club Executive Director Michael Brune and Sungevity Founder Danny Kennedy climbed on top of a home in Oakland to announce an innovative new partnership aimed at rapidly expanding rooftop solar in the Bay Area.

Sierra Club will be reaching out to its supporters in Northern and Central California and asking them to sign up for easy and affordable solar leasing through Sungevity. For each supporter who signs up, Sierra Club will receive $1,000 from Sungevity for its campaign to end reliance on fossil fuels and transition to a clean energy economy.

“In order to end our dependence on dirty energy, we need as many Americans as possible to switch to clean energy like rooftop solar. This is a high priority for Sierra Club. We are urging all of our members and supporters in Northern California to work with Sungevity to find out if solar is right for them. Every home that goes solar gets us one step closer to our goal of a clean energy economy,” said Brune.

“The new Sungevity-Sierra Club is a win-win-win scenario,” said Kennedy. “Sierra Club members benefit from the cost-savings of going solar, Sungevity builds on its network of energized customers and we all get a cleaner environment.”

Beginning today, Sierra Club members can lease or purchase a Sungevity solar energy system through Sierraclub.org/solar.

“I strongly encourage all Sierra Club members to start the easy process by logging on to Sierraclub.org/solar for a quick, free iQuote,” added Kennedy.

Sierra Club will use the activist tools it has honed over decades to ask consumers to switch to clean energy. Through house parties, phone banks and community organizing, the grassroots environmental group will encourage homeowners to go solar.

The partnership kicked off today at the Oakland home of Sierra Club member and Sungevity customer Dan Rademacher. Kennedy and Brune both discussed the environmental and financial benefits of residential solar leases from the rooftop of Rademacher’s home.

Electrification 2.0

Yesterday was the 76th anniversary of the creation of the Rural Electrification Administration (REA). In 1935, only 12% of rural households had electric service. The REA hit the ground running and, within four years, the number of electrified rural homes had doubled. By 1946, 54% had electricity and, today, it’s close to 100%.

If you plot a curve, you can see that the pace of rural electrification was exponential. FDR created the REA, and it immediately became the one of the most successful federal projects in US history, bringing thousands of jobs to severely economically depressed areas and raising the standard of living of millions of marginalized rural families. Though we take electricity for granted today, rural electrification in the 20th century revolutionized the lives of rural families who were by and large cut off from the mainstream US economy and culture.

The moral of the story is this: When the United States sets its sights on something great, it can achieve its goals with stunning speed and efficacy. The solar revolution is in its infancy. What if we double the number of solar homes within four years? What if half of all homes are solar ten years from now? The challenge of residential solar pales in comparison to the challenge of bringing electricity to homes in remote areas.  And the impact will be no less revolutionary.

Let’s ramp up the solar revolution — we’ll supply the panels, you just get us some roofs!

Happy Mother’s Day

Mother’s Day is this Sunday, but don’t worry -we’re not going to circulate yet another list of all the eco-friendly gifts you can buy for your mom. (After all, how many bamboo salad bowls does a woman need)?

Instead, we want to tell you about an incredibly exciting youth-led international day of action called the iMatter March.  iMatter is “a march for a planet worth inheriting.” It’s the brainchild of Kids vs. Global Warming founder, 16-year old Alec Loorz, who says:

Our society’s addiction to fossil fuels is messing with the perfect balance of nature and threatening the survival of our generation, the youth. It needs to stop, and we will not sit idly by as our leaders make decisions that affect our future…The iMatter March is our opportunity stand up and be heard on the most important issue of our time.

Dozens of local marches will take place on May 8, from Baltimore to Sebastopol to Seoul. Visit the iMatter website to find a march near you. If you can’t make it to the march, you can sign the petition calling on the government to protect our atmosphere. Your mother will be proud of you!

Cal State Fullerton Full of Sunshine

Cal State Fullerton is installing 5,000 solar panels and saving $8 million on their electricity bills. The system will have a combined rating greater than 1MW of power, and will be installed at 4 sites around campus. Additionally, the system will remove a total of 16,000 tons of CO2 emissions for the campus over the 25-year life of the panels.

With the prospect of a carbon price in California soon, the University is looking to make even more money from it’s solar solution. “If we used an average value for CO2 offsets, this would equate to an approximate value of an additional $1.5 million of savings to the campus that would bring the total value of the Solar PV Project to $9.5 million to the campus,” said Doug Kind, manager of commissioning and energy at the Physical Plant.

Schools and colleges going solar have had some tough love lately, so it is great to see Cal State going through with this money-saving leadership move at Fullerton. Students will be inspired by it and so am I. Shine on and thanks to Kamy West at the Daily Titan, CSU Fullerton’s student newspaper for this California Brightspot!
