Could the NT Develop Industrial Solar Energy Systems on Warehouse Roofs?

Don’t think it’s possible to provide clean and renewable energy that creates jobs and fuels private investment? Think again and then check out CLEAN LA Solar.

A program developed and supported by the Los Angeles Business Council, a coalition of environmental, business, health and research organizations, and the CLEAN LA Coalition, it’s the largest urban rooftop solar program in the nation. Its five-year goal is to power more than 34,000 homes while creating some 4,500 construction, installation, design engineering, maintenance and administrative jobs in Los Angeles.

CLEAN LA Solar allows businesses and commercial property-owners to generate energy for the city’s power grid through rooftop solar panels, and then sell the power to the Department of Water and Power (DWP). This policy is known as a feed-in-tariff (FiT), and is a great way to promote clean, solar energy.

California has a legislative requirement to generate 33 percent of its energy from renewable sources by 2020. Currently, most of L.A.’s renewable power is generated outside the L.A. basin and transmitted inefficiently to customers. By contrast, the CLEAN LA Solar program will provide incentives for clean-energy production within city limits. The result will be more efficient power delivery and a reduction in the city’s reliance on polluting, coal-fired power plants. The FiT also does not require new or upgraded transmission lines.

The goal is to generate 150 megawatts of solar electricity, or enough power for 30,000 homes. The business council hopes to attract investments totaling about $500 million from a group of companies that want to invest in the city’s push to go green. The program’s first project site is an 80-unit apartment building in North Hollywood that went online with 336 250-watt panels (for 84 kW of installed capacity) on June 26.

Solar Provider Group, the international solar firm behind the North Hollywood solar installation, moved its U.S. headquarters to a new office in downtown Los Angeles and is hiring employees. Over the next 18 months, SPG will hire up to 50 additional Los Angeles-based employees in sales, engineering, manufacturing and construction. The company plans to invest up to $50 million in the city by the end of 2016, over the course of the 100 MW program. SPG is also evaluating additional investments elsewhere in California and throughout the U.S.

While the CLEAN LA Solar program gets rolling, a rooftop solar provider is looking at a way to allow customers to be independent from utilities by generating their own power, according to an LA Times article.

Lyndon Rive, chief executive of San Mateo, Calif.-based SolarCity Corp., said in an interview with the paper that his rooftop solar company plans to roll out a system that would allow customers to generate power by solar panels during daylight hours and store the energy in battery packs at night.
These are not academic exercises or something on the drawing board that could happen on a large scale someday. It’s happening right now—a model for all urban areas to note.


There are some innovative steps being taken in some overseas locations to really try and move solar power into more mainstream options, as seen by this initiative.  As the costs fall, it definitely makes more sense to consider solar as a sensible option.

For the NT there are a lot of empty roof tops in the industrial areas of Darwin and nearby areas, above businesses that predominantly use electricity during sunshine hours.

It seems a no brainer that there must be development potential there, and it allows small increments of additional energy capacity at modest cost rather than having to opt for large chunks of energy increase at a time, which is how normal utility systems are developed.

Is it financing know how  that is restricting development and would better financing models offer better solutions?  Not my field........but it sure seems odd the NT is not doing more.

Yes, there are some issues with efficiency in crystalline panels in hot weather, of which we have plenty, but alternates are getting better and cheaper all the time.

Is it time for the NT too??
