Solar Solutions

A major challenge for states like California that are trying to meet renewable portfolio standards (RPS), standards which dictate the minimum percentage of electricity that a state needs to derive from renewable sources, is to find energy storage options that are both affordable and effective.

The main issue is that renewable technologies such as Los Angeles solar and wind power generate a lot of electricity at certain times of the day, and none at others. Particularly with wind energy, the electrical grid needs to be able to handle massive fluctuations in electrical production in a way that it is currently incapable of doing. This is due to the absence of battery technology that can be scaled to such sizes that it can handle gigawatt-hours of energy.

Reuters reports that California Governor Jerry Brown told attendees at the InterSolar Conference in San Francisco that Californians can’t simply rely on sunlight for power, saying that “we’ve got to bottle the sunlight.”

Fortunately, many companies are entering a heated race to develop batteries that can handle large amounts of grid electricity. These include LG Chem, a large-scale battery maker, in addition to more well-known companies such as General Electric, and investors Peter Thiel and Bill Gates. Brown put forward a proposal that would increase the state’s commitment to funding battery tech, which many see as the principle obstacle to wider integration of solar energy into the electric grid.

The more progress these firms can make on this front, the more Californians will be able to benefit from this great energy source.

The two main arguments that are often cited in favor of Los Angeles and Orange County solar power are economic and environmental. By going solar, residents and businesses can reduce and potentially eliminate their electricity bills. In doing so, people also help improve the planet’s climate by decreasing carbon dioxide emissions.

Those two reasons alone are enough to justify widespread adoption of solar power for electrical generation, but something that often goes unmentioned is the way that solar technology can help boost public health.

The reasoning is simple. Burning fossil fuels not only produces carbon dioxide but other forms of air pollution that can cause serious respiratory illnesses in children, adults and seniors. Even natural gas, which burns much cleaner than coal, still releases toxins into the air that can exacerbate health conditions such as asthma and obstructive pulmonary disease. According to Scientific American, particulates emitted from fossil fuel power production is estimated to cause 59,000 cases of acute bronchitis and 603,000 asthma attacks annually.

While this is a problem in many communities spread throughout the U.S., EarthTechling, a clean technology news site, points out that seven of the ten worst counties in the nation in terms of air pollution are located in California. Much of this air pollution comes from the production of electricity, and could be eliminated through greater reliance on solar power.

When considering the merits of having a rooftop PV system installed on your home or business, along with the environmental and financial advantages, keep in mind that you’ll also be contributing to improved public health.

Electric vehicles and plug-in models like the Chevy Volt, Tesla Model S, Nissan Leaf and BMW i3 are becoming much more viable options for customers looking to save money on gasoline and energy costs. EV technology used be to very expensive, and though it still remains on the high end of the price spectrum for many drivers, it’s quickly moving in the direction of being more affordable for many families.

At the same time, solar power is rapidly bringing renewable energy to a wider market of customers in Southern California.

So, this begs the question: Can energy users who want to capitalize on these trends take advantage of the economic and environmental benefits of both? Does having an all-electric or plug-in hybrid vehicle increase the value of a rooftop solar energy system?

In an article on GigaOM, a technology news site, writer Kevin C. Tofel, wrote about how he had installed solar photovoltaic (PV) panels on his home and bought a Chevrolet Volt. He claimed that the purchase of the car had shortened the solar payback period on his PV system by half.

Tofel figured that three-quarters of the family’s driving was powered by electricity from the solar panels, saving roughly $2,400 a year in gasoline costs. At the same time, Tofel was spending $2,500 less on electricity for his home annually, for a combined savings of $4,900. While he had originally projected the break-even point on his PV system to be about 11 years before buying the Volt, the gasoline savings after the purchase meant he would hit that point at about 6 years after buying the solar panels.

It’s worth mentioning that the results for solar customers in Orange County and Los Angeles could vary from Tofel’s. He purchased a relatively oversized system for his house, plus he lives in Pennsylvania, which has different incentives than California. But, it wouldn’t be very difficult for California customers to outpace these results, as electric rates and gasoline prices in the Golden State are much higher than those in Pennsylvania.

If you are interested in purchasing a solar system to offset electricity costs of your home and electric vehicle, contact AMECO Solar today. One of our solar consultants will be able to run the numbers to figure out the size of the solar system that you will need and how long it will take to hit the break-even point.

The Brightsource Ivanpah Solar Electric Generating System, in the Mojave Desert of California, is ready to go online, and pending approval by the California Public Utilities Commission should begin generating electricity very soon.

Located off the Interstate-15 near the Nevada border, the Ivanpah solar project is one of the largest ever completed. Using 170,000 mirrors, sunlight is concentrated and focused on three 450-foot tall towers. Water in the towers is heated to boiling temperatures, where it converts to steam and spins a turbine that generates electricity.

The total power capacity of the Ivanpah project is 392 megawatts (MW), enough to light 140,000 homes. The process produces no carbon emissions and qualifies as a renewable energy source.

The technology involved is very different from the photovoltaic panels that AMECO installs on rooftops, but the goal is the same: To provide a clean, affordable energy source to California residents that will reduce our dependence on fossil fuels and stabilize long term energy costs. The project is funded by Brightsource Energy, along with support from Google and NRG and a federal loan.

The completion of Ivanpah will help the state of California meet its renewable portfolio standard (RPS) goal of 33 percent by 2020. It has drawn some criticism for the impact the project has had on desert tortoise populations, but biologists hired by Brightsource have relocated the animals to alternative locations where they can thrive.

By integrating more California solar energy into the state’s electrical grid, plants like the one at Ivanpah allow more Californians to reap the financial, economic and environmental benefits of solar power.
