Other sources suggest 6-8 acres for each megawatt of power produced is needed to build a profitable solar farm. The bigger the solar farm, the greater the power output. Provided by the Springer Nature SharedIt content-sharing initiative, Journal of the Indian Society of Remote Sensing (2022). natural gas). . Prados, M. J. Renewable energy policy and landscape management in Andalusia, Spain: the facts. To the back of the envelope! Solar energy in urban areas, deserts and dry scrublands, as well as bioenergy from waste or agricultural and forestry residue, are assumed not to contribute to LUC emissions nor carbon sequestration. For instance, a 5 MW (megawatt, where 1 MW = 1,000 kW) solar farm would require a minimum of 100 x 5,000 = 500,000 sq. and JavaScript. Article & Sorman, A. H. Energy transitions and the global land rush: ultimate drivers and persistent consequences. 49% of power plants: Within 2.5 and 3.5 acres/GWh/yr. This ratio increases with higher penetration rates, due to the satiation of the potential to generate solar energy on rooftops (see also Figure S12 in the SM) in combination with the decreasing marginal returns for land-based solar energy. See Methods section and Figure S1 of the SM for more information on the spatial resolution used in this study. However, it also shows that the design and management of solar parks is of high importance for the carbon cycle in such parks. Therefore, apart from the 10% of scrublands which enter by default into the land competition module, we assumed no additional availability of suitable deserts and scrublands for solar energy in these regions. Photovolt. Energy Policy 39, 11541169 (2011). Copyright 2023 IEEE All rights reserved. Prospects of life cycle assessment of renewable energy from solar photovoltaic technologies: a review. Impacts of photovoltaic farms on the environment in the Romanian Plain. In the three regions, a large part of the total built-up area (urban and solar land) will consist of solar PV panels or CSP heliostats by 2050 if at least half of the produced electricity comes from solar power. To date, land use for solar energy is negligible compared to other human land uses. Depending on the specific technology, a utility-scale solar power plant may require between 5 and 10 acres per megawatt (MW) of generating capacity. The countrys largest wind farm, Alta Wind Energy Center in California, has an installed capacity of 1,548 MW. ADS to be used for a high level estimation of initial system capacity. Typically, utility solar power stations are huge in comparison to community solar farms. However, the obtained results show that in future scenarios, with a largely decarbonized electricity system, high penetration rates of solar energy will require significant amounts of land to be occupied by solar power plants. In contrast, if arable land plots are converted to solar parks whose surface is managed as pastures, there will be a net carbon sequestration in vegetation and soil in the decades following upon the conversion (apart from the land directly below the panels, where photosynthesis is largely blocked)35, offsetting some or all of the inevitable LUC emissions caused by land competition. The image below, also courtesy of the NREL report, shows both direct and total land use of a solar PV system. Lett. As a general rule of thumb, a 1 MWac (alternating current) solar farm requires 4-7 acres of land. To give you a better idea of the type of solar power station that could operate on your land, consider a community solar farm. GCB Bioenergy 4, 372391 (2012). The most land-intensive plan eliminates all nuclear plants. Renew. In the case of solar energy, the land competition element is usually expected to be negligible due to its higher relative energy density compared to bioenergy and the possibility to integrate it in urban areas or non-productive land7,14,15,16, and as such is currently excluded from official statistical reporting and integrated assessment models (IAMs). The table below, courtesy of the National Renewable Energy Laboratory, highlights the differences in land-use requirements for PV and CSP projects across the United States. This structure is based on observed tendencies for solar siting in Europe, India, Japan and South-Korea (see Table S2 in SM), showing that mainly arable land is used for current USSE projects, and supported by academic literature17,33,34,57,58 and solar industry reports59,60. 1 crore and 25 lakh. Areas directly below solar modules are cleared for the construction phase, but weeds might grow after that phase. Today, anyone can set up a solar power plant with a capacity of 1KW to 1MW on their land or rooftops. A. et al. . At higher solar penetration rates however, increasing land pressure causes more natural forests to be used for timber or crop production, leading to higher land use change emissions outside the region. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Ovando, P. & Caparrs, A. Joule 2, 26182632 (2018). They have much to gain from you and want you to sign on with them. As long as you meet the minimum solar farm land requirements, solar leasing is an easy and consistent way to generate income. How much does it cost to set up a solar farm? The projected land cost per acre is Rs.5 lakhs. Sample calculation for determining the size of a solar farm. 16, 449465 (2012).

Minerva Fellowship Programme. Green Coast is supported by its readers. With solar energy accounting for 25 to 80% of the electricity mix, land occupation by USSE is projected to be significant, ranging from 0.5 to 2.8% of total territory in the EU, 0.3 to 1.4% in India, and 1.2 to 5.2% in Japan and South-Korea. Renew. Adeh, E. H., Good, S. P., Calaf, M. & Higgins, C. W. Solar PV power potential is greatest over croplands. Liu, F. & van den Bergh, J. C. J. M. Differences in CO2 emissions of solar PV production among technologies and regions: application to China, EU and USA. When using relatively efficient PV technologies such as monocrystalline and multicrystalline silicon (made from a single crystal of silicon and from many silicon fragments melted together, respectively) (lower range of estimated LUC emissions, higher range of non-land life cycle emissions), our results show that LUC emissions are comparable to about 10 to 50% the current non-land life cycle emissions for such technologies. Due to the lower irradiance and higher latitude of Europe, absolute land use of per unit of solar output is almost twice as high as in Japan and South-Korea and three times higher as in India (see Fig S6 in the SM). ADS The most land-intensive plan eliminates all fossil fuels and nuclear plants. Fargione, J., Hill, J., Tilman, D., Polasky, S. & Hawthorne, P. Land clearing and the biofuel carbon debt. A.) To extend the analysis performed in this study to other regions, it is important to have a well-quantified potential for solar energy in areas that are not suitable to host other commercial land uses such as agriculture and forestry. Hence, a coordinated planning and regulation of new solar energy infrastructuresshould be enforced to avoid a significant increase in their life cycle emissions through terrestrial carbon losses. Direct-area requirements: Generation-weighted average is 2.9 acres/GWh/yr. 5 lakh per acre. Land use and space issues have long been a point of contention when it comes to renewables, with opponents complaining that the huge spaces required for solar and wind aren't worth the effort. Modules are placed slightly higher to avoid potential shading from vegetation. In this article, youll find out everything you need to know about solar farms as a way to create a steady income from your land for 25-50 years. If youre able to hire a savvy lawyer who will tirelessly advocate for you during contract negotiations with a solar developer, you could make sure annual rent increases are included as well as adjustments for inflation. Science (80-. ) I.C. On average, a 1kW solar system requires a shade-free area of 6 square meters. Technoecological synergies of solar energy for global sustainability. . Sci.

Denholm, P. & Margolis, R. M. Land-use requirements and the per-capita solar footprint for photovoltaic generation in the United States. Note thats just for the panels. The land occupation ratio, defined by Eq. At the domestic level, solar energy is found to predominantly compete for land with cropland and managed forests, while on a global scale, 27 to 54% of the land required for solar energy is found to indirectly displace unmanaged forests, predominantly outside the region where the solar energy is consumed. A minimum of 5 acres of land is required for a 1 MW plant in this country, which means that a 5 MW solar power plant will cost Rs. Therefore, where available, deserts and dry scrubland with high solar irradiance and which are generally not suitable for human activities, are used or planned to be used for solar energy26,27,28. For simplicity, we have based the PF estimation on fixed tracking PV systems on flat land. The new report says that a PV plant capable of powering 1 000 homes needs 32 acres. Those land-use categories (e.g. The range is calculated by dividing the regionally weighted solarelectricity output per m2 as used in this study, by CO2 emissions per m2 panel surface. 15, 32613270 (2011). Such a facility would require between 260 square miles and 360 square miles of land. To sum up, the total BOS costs in USD/Wp increases . Denholm, P. & Margolis, R. Supply curves for rooftop solar pv-generated electricity for the United States. Sci Rep 11, 2907 (2021). One study looked at what it would take to produce 10 percent and 100 percent of the whole world's power from various sources, and found nuclear and geothermal energy at the very lowest end of area needs, followed by coal, CSP, and natural gas. However, if they wish to build numerous small solar parks in a particular region due to local tax incentives that encourage the creation of community solar projects, a small land parcel will be perfect. Factors that affect solar farm lease rates, 2. According to an in-depth report from the National Renewable Energy Laboratory (NREL), the land-use requirements for solar power plants are wide ranging across different technologies. https://www.nrel.gov/docs/fy13osti/56290.pdf, You can own your own solar panels for as low as $0 down and 60 payments of $60, Facebook Twitter LinkedIn Instagram YouTube, New York | 79 Madison Avenue 8th Floor, New York, NY 10016 |212.389.9215, California | 1161 Mission Street,San Francisco, CA 94103 | 415.960.3144, the National Renewable Energy Laboratory (NREL). Nonhebel, S. Land-use changes induced by increased use of renewable energy sources. As the land use impacts of bioenergy have been extensively analysed in other studies, using the same model9,39, we proceed to compare the land occupation and related LUC emissions of electricity production from solar energy and bioenergy, with the purpose of improving the comparability of the obtained results. A 5 MW solar farm requires approximately 30 to 40 acres of land. Planning guidance for the development of large scale ground mounted solar PV systems (2013). Our results show that this changes in scenarios with a high share of solar energy in the future electricity mix. A not-for-profit organization, IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. & Frechoso, F. Global solar electric potential: a review of their technical and sustainable limits. As countries, states, and municipalities transition toward phasing out fossil fuels as energy sources, they are actively looking to expand clean energy capacity namely, solar and wind energy in their jurisdictions. When weighted by generation rather than capacity, the larger PV plants (3.4 acres per gigawatt-hour per year) and CSP plants (3.5 acres/GWh/year) do a bit better than smaller PV plants (4.1 acres/GWh/year). De Marco, A. et al. Proc. The technologies harnessing renewable energy sources are characterized by a power density several orders of magnitude lower than fossil fuels1. Equation(4) defines this yield for each AEZ, which depends on average solar irradiation (I) per AEZ, average efficiency of solar power plants (f1) at the year of installation (t), the averaged performance ratio over the life cycle of the solar power plant (f2) and the land occupation ratio (f3)1,17. Click here to download the full report from the National Renewable Energy Laboratory and gain a greater understanding of the land-use requirements for solar power plants. https://www.eu-japan.eu/publications/japanese-solar-pv-market-and-industry-business-opportunities-european-companies (2014). Anal. During the exploratory phase of a solar farm project, extensive testing on your land could result in significant crop damage that youre left to repair or remove. Martn-Chivelet, N. Photovoltaic potential and land-use estimation methodology. Figure2 shows that, either directly or indirectly, expansion in solar energy predominantly reduces non-commercial land cover on a global scale: for every 100 hectares of solarland in the EU, we find that, depending on the solar penetration level, 31 to 43 hectares of unmanaged forest may be cleared throughout all the world. Sustain. Geothermal energy might be the best of the bunch, though, in the low single digits. Solar photovoltaic (PV) facilities require up to 75 times the land area. 70, 161184 (2017). To generate 100 MW electricity (power), around 303 acres (approximately 123 hectares) of the wetland is required keeping the distance of 2.35 m between every two adjacent solar panel. and so this should be taken into account when reading their report. Power Technology. Further background assumptions related to the modelling can be found in the SM. This means that a solar power plant that provides all of the electricity for 1,000 homes would require 32 acres of land. Default system size values from NREL tools such as Renewable Energy Optimization (REopt) Complete Guide to Solar Power Output, Living Next to a Solar Farm: Pros and Cons, 8 Best Boat Solar Panels in 2023 to Power Your Boat Sustainability. For a quick return on investment, solar developers are usually unwilling to build a solar farm under 1 MW in capacity. Trieb, F., Schillings, C., Pregger, T. & OSullivan, M. Solar electricity imports from the Middle East and North Africa to Europe. The packing factor again depends on the average latitude of each AEZ and is defined by Eq. Appl. A combination of technical and geopolitical reasons complicates the installation of solar energy far from consumption points. This means that your property whether big or small could be a candidate for leasing a solar farm. Here are the most important. A solar PV facility must have an installed capacity of 3,300 MW and 5,400 MW to match a 1,000-MW nuclear facilitys output, requiring between 45 and 75 square miles. In the absence of land management practices specifically aiming at carbon sequestration, land cover change due to the expansion of solar energy in the EU would cause 13 to 53g of CO2 per produced kilowatt-hour (kWh) of electricity, about 4 to 16% of the CO2 emissions from natural gas fired electricity. Article no seeding, no herbicides) with land conservation (i.e. The background scenario for the model exercises in this study consist of the Middle of the Road Shared Socioeconomic Pathway (SSP 2)52 with global CO2 reduction targets as defined by the Nationally Determined Contributions (NDCs) with increased ambitions after 203053. Habitat Int. 93, 178200 (2018). Gasparatos, A., Doll, C. N. H., Esteban, M., Ahmed, A. Hernandez, R. R. et al. For example, higher placed modules are beneficial for vegetation growth below the modules, as it allows more sunlight to reach the vegetation. Sustain. Table 1 shows that land requirements for reaching certain levels of electricity penetration with solar energy are about a magnitude lower than land requirements to meet those same levels with bioenergy. NREL. Non-land-occupying pathway (NL): wind, geothermal, rooftop-based PV (and nuclearin scenarios where penetration level cannot be reached with the first 3 technologies together). Energy 71, 255262 (2014). Energy Rev.

Solar energy: markets, economics and policies. They also want to purchase renewable energy instead of electricity generated from fossil fuels. Energy Policy 138, 111234 (2020). CAS The projected cost of land is Rs. Article The impacts of each of these solarland management regimes on the local carbon cycle depend on the specific location, and the previous land use, and result from off-model calculations applied to the GCAM scenario outcomes which provide land cover changes per year, AEZ, and scenario. https://www.nrel.gov/docs/fy12osti/51946.pdf (2012). Solar farms in areas that get plenty of sun year-round, such as the southwestern United States, will generate more energy per acre than solar farms in the northern states. Solar developers want you to partner with them in solar projects that generate electricity. This amounts to about $500,000 per acre. Well include a full table further down, but these are some of the key numbers from the report. Article Change Econ. Solar farm land requirements in the United States, as measured by megawatts (MWac) of electrical power generated. To build the amount of wind and solar needed to support the grid, the U.S. energy footprint would quadruple in size, and wind farms would occupy areas equivalent to Arkansas, Iowa, Kansas, Missouri, Nebraska and . McFadden, D. Conditional logit analysis of qualitative choice behavior. The authors declare no competing interests. Sometimes, the RPS will accompany tax incentives for solar projects, making solar farm projects even more attractive to both developers and farmers. IEEE websites place cookies on your device to give you the best user experience. Trainor, A. M., McDonald, R. I. Figure in an additional 8-10 acres more to house other solar system hardware plus the space needed between rows to avoid shading (and consequent power loss) as well as space for periodic array maintenance. Conserv. Note that these results do only focus at solar and bioenergy based in land with potential commercial use. 4 to 5 acres of land is required for 1MW solar plant: Different Types of 1MW Solar Power Plants. See Section1a of the SM for a wider description of the model. Such land use decisions are based on the logit model of sharing, taking into account the heterogeneity of local circumstances within each AEZ, and avoiding extreme winner-takes-it-all outcomes55. Change 5, 604 (2015). Change 5, 353358 (2015). The numbers arent good news or bad news, said Paul Denholm, one of the report's authors, in a press release. However, since the physical characteristics of bioenergy allow for trade over large distances, comparable to fossil fuels and in contrast to electricity from solar energy, only a limited part of the land requirements and related LUC emissions driven by bioenergy expansion is projected to be within the EU, India, Japan and South-Korea. 3 and Table 2) from 2020 to 2050 have been calculated using Eq. Source: Authors own elaboration with the Arc GIS 10.5.1 Desktop (Esri) software. forest or pasture). The EU, Japan and South-Korea have limited amounts of deserts and scrublands (see Table S4 in the SM), and of which a significant share is protected69. Community solar members purchase shares of the energy created on your solar farm. A 100 MW of a solar power plant would require less than 10% of the total land area. Additionally, policy and regulation surrounding land-use for solar is also. Therefore, a high share of solar generation in the energy mix in relatively densely populated regions with high per capita energy demands can require a significant share of domestic land, comparable to the current built-up area in these regions. Farmers, ranchers, and landowners in search of a predictable way to receive passive income should determine if they meet the solar farm land requirements for leasing a solar project on their property.
