Solar Power In Hawaii
Energy in Hawaii, The energy sector in Hawaii has rapidly adopted solar power due to the high costs of electricity, and good solar resources, and has one of the highest per capita rates of solar power in the United States. Hawaii's United States energy independence, imported energy costs, mostly for imported petroleum and coal, are three to four times higher than the mainland, so Hawaii has motivation to become one of the highest users of solar energy. Hawaii was the first state in the United States to reach grid parity for photovoltaics. Its tropical location provides abundant ambient energy. Much of Hawaii's solar capacity is distributed solar panels on individual homes and businesses. Hawaii's grid has had to deal with this unique situation by developing new technology for balancing the energy flows in areas with large amounts of solar power. In 2023, distributed solar produced 1,408 GWh while utility-scale solar produced 643 GWh. Hawaii had 1,808 MW of installed solar capacity ...

Virtual Power Plant
A virtual power plant (VPP) is a system that integrates multiple, possibly heterogeneous, power resources to provide grid power. A VPP typically sells its output to an electric utility. VPPs allow energy resources that are individually too small to be of interest to a utility to aggregate and market their power. As of 2024, VPPs operated in the United States, Europe, Asia and Australia. One study reported that VPPs during peak demand periods are up to 60% more cost effective than peaker plants. Distributed energy resources VPPs typically aggregate large numbers of distributed energy resources (DER). Resources can be dispatchable or non-dispatchable, controllable or flexible load (CL or FL). Resources can include microCHPs, natural gas-fired reciprocating engines, small-scale wind power plants (WPP), photovoltaics (PV), run-of-river hydroelectricity plants, small hydro, biomass, backup generators, and energy storage systems such as home or vehicle batteries (ESS), and devic ...

Lanai
Lānai is the sixth-largest of the Hawaiian Islands and the smallest publicly accessible inhabited island in the chain. It is colloquially known as the Pineapple Island because of its past as an island-wide pineapple plantation. The island's only settlement of note is the small town of Lānai City. The island is 98% owned by Larry Ellison, cofounder and chairman of Oracle Corporation; the remaining 2% is owned by the state of Hawaii or individual homeowners. Lānai has a land area of , making it the 43rd largest island in the United States. It is separated from the island of Molokai by the Kalohi Channel to the north, and from Maui by the Auau Channel to the east. The United States Census Bureau defines Lānai as Census Tract 316 of Maui County. Its total population rose to 3,367 as of the 2020 United States census, up from 3,193 as of the 2000 census and 3,131 as of the 2010 census. As visible via satellite imagery, many of the island's landmarks are accessible only by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solar Thermal
Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in Industrial sector, industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors. Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use. High-temperature collectors concentrate sunlight using mirrors or Lens (optics), lenses and are generally used for fulfilling heat requirements up to () / 20 Bar (unit), bar (300 psi) pressure in industries, and for electric power production. Two categories include Concentrated Solar Thermal (CST) for fulfilling heat requirements in industries, and concentrated solar power (CSP) when th ...

Concentrating Solar Power
Concentrated solar power (CSP, also known as concentrating solar power, concentrated solar thermal) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight into a receiver. Electricity is generated when the concentrated light is converted to heat (solar thermal energy), which drives a heat engine (usually a steam turbine) connected to an electrical power generator or powers a thermochemical reaction. As of 2021, global installed capacity of concentrated solar power stood at 6.8 GW. As of 2023, the total was 8.1 GW, with the inclusion of three new CSP projects in construction in China and in Dubai in the UAE. The U.S.-based National Renewable Energy Laboratory (NREL), which maintains a global database of CSP plants, counts 6.6 GW of operational capacity and another 1.5 GW under construction. Comparison between CSP and other electricity sources As a thermal energy generating power station, CSP has more in common with thermal power st ...

Sopogy
Sopogy short for Solar Power Technology was a solar thermal technology supplier founded in 2002 at the Honolulu, Hawaii-based clean technology incubator known as Energy Laboratories. The company began its research on concentrating solar thermal energy to produce solar steam and thermal heat for absorption chillers or industrial process heat. The company has also developed applications that incorporate its solar collectors to generate electricity and desalination. Sopogy's name origin comes from industry key words "So" from ''so''lar "po" from ''po''wer and "gy" from ener''gy'' and technolo''gy''. The company has its OEM and IPP sales teams along with research and development located in Honolulu, and in 2006 expanded its manufacturing, C&I and oil and gas sales teams in its Silicon Valley facility. ''Pacific Business News'' and Greentech Media reported that the VC-funded micro-concentrator solar power firm was shutting down operations based on statements from its President David ...

Shopping Mall
A shopping mall (or simply mall) is a large indoor shopping center, usually Anchor tenant, anchored by department stores. The term ''mall'' originally meant pedestrian zone, a pedestrian promenade with shops along it, but in the late 1960s, it began to be used as a generic term for the large enclosed shopping centers that were becoming increasingly commonplace. In the United Kingdom and other countries, shopping malls may be called ''shopping centres''. In recent decades, malls have declined considerably in North America, partly due to the retail apocalypse, particularly in subprime locations, and some have closed and become so-called "dead malls". Successful exceptions have added entertainment and experiential features, added big-box stores as anchors, or converted to other specialized shopping center formats such as power center (retail), power centers, lifestyle centers, factory outlet centers, and festival marketplaces. In Canada, shopping centres have frequently been repl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunetric
Sunetric is a Hawaii-based photovoltaic solar power company that performs consultation, design, and installation of photovoltaic systems for residential, commercial, military, and non-profit customers. Sunetric operates on all of the Hawaiian islands and in several states in the continental US. The company was founded in 2004 as Suntech Hawaii by Sean Mullen. Alex Tiller is the company's CEO.

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation does not generate any pollution or any greenhouse gas emissions; it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required ...
