Photovoltaic Power Plant
A photovoltaic power station, also known as a solar park, solar farm, or solar power plant, is a large-scale grid-connected photovoltaic power system (PV system) designed for the supply of merchant power. They are different from most building-mounted and other decentralised solar power because they supply power at the utility level, rather than to a local user or users. The generic expression utility-scale solar is sometimes used to describe this type of project. The solar power source is solar panels that convert light directly to electricity. However, this differs from and should not be confused with concentrated solar power, the other major large-scale solar generation technology, which uses heat to drive a variety of conventional generator systems. Both approaches have their own advantages and disadvantages, but to date, for a variety of reasons, photovoltaic technology has seen much wider use. , about 97% of utility-scale solar power capacity was PV. In some countries, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tax Credit
A tax credit is a tax incentive which allows certain taxpayers to subtract the amount of the credit they have accrued from the total they owe the state. It may also be a credit granted in recognition of taxes already paid or a form of state "discount" applied in certain cases. Another way to think of a tax credit is as a rebate. Refundable vs. non-refundable A refundable tax credit is one which, if the credit exceeds the taxes due, the government pays back to the taxpayer the difference. In other words, it makes possible a negative tax liability. For example, if a taxpayer has an initial tax liability of $100 and applies a $300 tax credit, then the taxpayer ends with a liability of –$200 and the government refunds to the taxpayer that $200. With a non-refundable tax credit, if the credit exceeds the taxes due then the taxpayer pays nothing but does not receive the difference. In this case, the taxpayer from the example would end with a tax liability of $0 (i.e. they could ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agrivoltaics
Agrivoltaics, agrophotovoltaics, agrisolar, or dual-use solar is the simultaneous use of areas of land for both solar photovoltaic power generation and agriculture. The coexistence of solar panels and crops implies a sharing of light between these two types of production, so the design of agrivoltaic facilities may require trading off such objectives as optimizing crop yield, crop quality, and energy production. However, in some cases crop yield increases due to the shade of the solar panels mitigating some of the stress on plants caused by high temperatures and UV damage. The technique was originally conceived by Adolf Goetzberger and Armin Zastrow in 1981, and the word ''agrivoltaic'' was coined in 2011. Today, agrivoltaic practices and the relevant law vary from one country to another. In Europe and Asia, where the concept was first pioneered, the term ''agrivoltaics'' is applied to dedicated dual-use technology, generally a system of mounts or cables to raise the solar array s ...

Urban Heat Island
An urban heat island (UHI) is an urban or metropolitan area that is significantly warmer than its surrounding rural areas due to human activities. The temperature difference is usually larger at night than during the day, and is most apparent when winds are weak. UHI is most noticeable during the summer and winter. The main cause of the UHI effect is from the modification of land surfaces. A study has shown that heat islands can be affected by proximity to different types of land cover, so that proximity to barren land causes urban land to become hotter and proximity to vegetation makes it cooler. Waste heat generated by energy usage is a secondary contributor. As a population center grows, it tends to expand its area and increase its average temperature. The term heat island is also used; the term can be used to refer to any area that is relatively hotter than the surrounding, but generally refers to human-disturbed areas. Monthly rainfall is greater downwind of cities, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albedo
Albedo (; ) is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. Surface albedo is defined as the ratio of radiosity ''J''e to the irradiance ''E''e (flux per unit area) received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as obtained from flux measurements) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brownfield Land
In urban planning, brownfield land is any previously developed land that is not currently in use. It may be potentially contaminated, but this is not required for the area to be considered brownfield. The term is also used to describe land previously used for industrial or commercial purposes with known or suspected pollution including soil contamination due to hazardous waste. Examples sites include abandoned factories, landfills, dry cleaning establishments and gas stations. Typical contaminants include hydrocarbon spillages, solvents and pesticides, as well as heavy metals like lead, tributyl tins and asbestos. Many contaminated brownfield sites sit unused for decades as involuntary parks because cleaning cost is more than land worth after redevelopment. Previously unknown underground wastes can increase the cost for study and clean-up. Acquisition, adaptive re-use, and disposal of a brownfield site requires advanced and specialized appraisal analysis techniques. Rem ...

List Of Photovoltaic Power Stations
The following is a list of photovoltaic power stations that are larger than 300 megawatts (MW) in current net capacity.Note that nominal power may be AC or DC, depending on the plant, and therefore any totals quoted are hybrid. SeAC-DC conundrum: Latest PV power-plant ratings follies put focus on reporting inconsistency (update) Most are individual photovoltaic power stations, but some are groups of co-located plants owned by different independent power producers and with separate transformer connections to the grid. Wiki-Solar reports total global capacity of utility-scale photovoltaic plants to be some 96 GWAC which generated 1.3% of global power by the end of 2016. The size of photovoltaic power stations has increased progressively over the last decade with frequent new capacity records. The 97 MW Sarnia Photovoltaic Power Plant went online in 2010. Huanghe Hydropower Golmud Solar Park reached 200 MW in 2012. In August 2012, Agua Caliente Solar Project in A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feed-in Tariffs In Germany
Feed-in electricity tariffs (FiT) were introduced in Germany to encourage the use of new energy technologies such as wind power, biomass, hydropower, geothermal power and solar photovoltaics. Feed-in tariffs are a policy mechanism designed to accelerate investment in renewable energy technologies by providing them remuneration (a "tariff") above the retail or wholesale rates of electricity. The mechanism provides long-term security to renewable energy producers, typically based on the cost of generation of each technology. Technologies such as wind power, for instance, are awarded a lower per-kWh price, while technologies such as solar PV and tidal power are offered a higher price, reflecting higher costs. As of July 2014, feed-in tariffs range from 3.33 ¢/kWh (4.4 ¢/kWh) for hydropower facilities over 50 MW to 12.88 ¢/kWh (17.3 ¢/kWh) for solar installations on buildings up to 30kWp and 19 ¢/kWh (25.5 ¢/kWh) for offshore wind. On 1 August 2014, a revised Renewable Ene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hesperia, California
Hesperia is a city in San Bernardino County, California, United States. It is located north of downtown San Bernardino in Victor Valley and surrounded by the Mojave Desert. Because of its relatively high elevation and the unique and moderate weather patterns of the region, Hesperia is part of what is locally called the High Desert. The name "Hesperia" means "western land". The 2019 census report estimates that the city has a population of 95,750. History The first inhabitants of the area were the Desert Serrano ( Vanyume). The village of Wá’peat, among several other villages that were located along the Mojave River, were within the vicinity of what is now Hesperia. These villages were occupied into the early 1800s and had deep ties with one another. An acorn-gathering festival was held at Wá’peat that involved villagers from across the Mojave River area. Hesperia began as a Spanish land grant: ''Rancho San Felipe, Las Flores y el Paso del Cajon'', founded in 1781. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
