Our Commercial Customers

On October 24, the U.S. Interior Department’s Bureau of Land Management (BLM) will begin auctioning off the first of its Solar Energy Zones (SEZ), areas that it has designated as prime real estate for the development of utility-scale solar power plants.

The BLM will be accepting bids from developers for the rights to begin the process of designing and constructing new solar installations, part of a larger effort to promote renewable energy sources.

<h3>What is a Solar Energy Zone?</h3>

SEZs are large parcels of land that have been selected as ideal spaces to create new solar energy generating stations. Typically, they are selected because they are not used for other types of develop such as residential, commercial or industrial facilities, or because they are located on old landfills, garbage dumps and Superfund sites that are unfit for human habitation.

<h3>Solar Energy Zones in California and Other States</h3>

The first two sites that will be auctioned off are located in Colorado. However, there are two SEZs in California located in the Imperial East and Riverside East regions. The latter is the largest zone currently listed for auction, offering almost 150,000 acres of developable land (originally it was over 200,000, but about 50,000 acres were removed to reduce the impact on nearby Joshua Tree National Park).

The SEZ plan is an attempt to tackle two problems simultaneously:

1) Find enough land to build large scale projects.
2) Make use of areas that are otherwise uninhabitable due to environmental and sanitation factors.

While there is still plenty of progress to be made on the small-scale, distributed generation front, AMECO Solar is happy to see that the federal government continues to advance an agenda the prioritizes solar power over fossil fuels and other non-renewable sources.

The California Public Utilities Commission (CPUC) has announced that pools for commercial or public use will now be eligible to claim rebates from the California Solar Initiative (CSI) for installing solar pool heater systems. The CPUC expanded its definition of eligible facilities to include any pools for multifamily residential housing, hotels and motels, therapy, educational, governmental and non-profit institutions.

The CSI Thermal Program will pay $7.00 for every therm that is displaced annually by the installation of a solar pool system. As more of the funding for this program is subscribed, the per-therm rebate will decrease. Participating pool owners will receive a one-time payment that is based on a calculation of estimated future therm displacement.

The expansion of the CSI-Thermal program for hot water to public pools could be a major benefit for recreational and educational facilities throughout the state. Water heating costs for these institutions are typically one of their biggest expenses, so any way that they can save money will benefit those who use the community pools.

Organizations such as the YMCA and other community centers can realize significant savings. AMECO Solar recently completed the installation of a solar pool heating system on the roof of the California Aquatics Therapy & Wellness Center in Long Beach, California. Now that they are heating their pool with solar energy and the organization is saving upwards of $13,000 a year, which will add up to almost $250,000 in savings during the life time of the solar pool heater.

In mid-August, the CPUC also approved commercial facilities to receive rebates from the Thermal Program. This decision opens the doors for gyms, water parks and other enterprises to lower their expenses and help steer the state toward a renewable energy future. The final details of the program are scheduled to be finalized at the California Public Utilities Commission by November, 2013.

A new report titled  “Solar Heating & Cooling: Energy for a Secure Future” lays down a plan for the expansion of solar heating and cooling (SHC) systems.

By educating the public and policymakers about the benefits and availability of solar thermal water heating solutions, SEIA hopes to expand the rebates available for the technology as a way to increase the amount of solar energy usage throughout the United States.

Media coverage of the solar industry tends to pay more attention to its impact on the energy sector. Although this is certainly a crucial area where photovoltaic (PV) power can have a positive effect on energy consumption and carbon emissions, it should be noted that 44 percent of energy consumption in the U.S. comes from heating and cooling applications, such as water and space heating, air conditioning and steam generation. This is where solar thermal applications can play a larger part.

SEIA recommends that the United States set a goal of increasing its solar thermal capacity from 9 gigawatts (GW) to 300 by 2050. Doing so could provide the American economy with $61 billion in annual savings, while helping to create over 50,000 jobs and increase manufacturing output by $1.9 billion. It would also offset 226 million tons of CO2 emissions annually, which is similar to take 47 million passenger cars off the road.

Among the policy prescriptions that Pilgaard and his colleagues propose is an expansion of incentive programs that are already in place to encourage more homeowners, businesses and institutions to adopt solar energy for their heating and cooling needs. These include renewable energy tax credits, rebates for SHC systems and ensuring that renewable portfolio standards, which require utilities to procure a certain amount of their energy from renewable sources.

They want to make sure that when homeowners decide to rely on Orange County or Los Angeles solar power for their water heating and temperature control needs, they receive similar credits and rebates as if they had installed a solar electric system.

In the past few years, the United States has made great strides to better integrate solar energy into the electric grid. Hopefully, the American public and elected officials can make similar efforts to expand the role of SHC systems.

Last Sunday, the AMECO Solar team attended the Solar Decathlon at the Orange County Great Park in Irvine, California. We walked through the Solar Village where 19 solar-powered, energy efficient homes were designed and built by collegiate teams from around the world.

While it was inspiring to see the students’ innovative approach to solar electric and thermal installation, we were most impressed by their enthusiasm about solar energy and energy efficiency. You could see they took pride in their work and were enthusiastic to share the knowledge gained over the two years it took to prepare for the competition. AMECO Solar staff came away from the event with some favorites.

West Virginia University’s PEAK

The home was designed as a modern take on a typical Appalachian home with cabin-like features and lots of wood detailing. It boasts a living garden on the rooftop along with a PV array and solar hot water panels. Energy usage from the entire home can be accessed through a tablet or mobile device so that home owners can track their consumption and adjust their usage accordingly. This home has a particularly cozy atmosphere and seemed the most live-ready. Also, we felt that the overall design has a wider appeal than some of the other uber modern homes in the Solar Village.

University of Southern California’s fluxHome

When you first walk up to the USC solar home, you immediately notice the metal-like covering. It’s a thermally responsive envelope around that house that regulates air flow and provides additional insulation. Inside, the bedrooms open up to the main living area where the kitchen, living room and dining room are all in one large space with a loft-like feel. We like how the solar panels were installed in a discrete way so that they were not visible from the walkway. But, sometimes it’s the little things that count. We were most impressed by the retractable skylight in the bathroom that automatically opens and closes. Not only is the skylight a beautiful architectural accent, but it’s also built for function as it lets warm air exit easily to keep the house cool.

Stanford University’s Start.Home

Knowing that all families are different, Stanford designed a modular home built around a mechanical room that houses the equipment for the solar electric and thermal systems. Home owners can easily customize the home by adding additional bedrooms or offices as needed. We were most intrigued by the prototypes that the team created. For example, each room has a special light switch where you can turn lights on and off with quick swipe (similar to a swipe you would use on an iPad or mobile phone). By swiping the switch with four fingers, you can turn the power off in the specific room allowing for more energy conservation (a lot easier than unplugging all your devices when leaving a room).

Each solar home is measured in 10 different contests ranging from architectural design and market appeal to affordability and energy balance. As of today, Santa Clara University is currently in the running for first place with University of Nevada Las Vegas not far behind.

You can see photos of the solar homes on the AMECO Solar Facebook page. If you are in the Los Angeles or Orange County areas, you still have time to see the event in person. Public viewing hours for the Solar Decathlon start up again today and will extend through the weekend. Visit the Solar Decathlon website for more info.
