Solar energy is rapidly becoming a popular and sustainable source of power. With the increasing demand for renewable energy sources, it's essential to identify the best locations in the United States for solar energy development. In this blog, we will take a high-level look at siting locations for solar farm development, factors to consider, and tools to help streamline the process.
Solar Farm Land Requirements
Solar farm development requires careful consideration of land requirements to ensure optimal efficiency and productivity. By carefully considering land size, layout, quality, and topography, developers can select the most suitable locations for solar farm projects. This strategic approach ensures maximum energy generation and contributes to the overall success and sustainability of solar farm ventures. LandGate’s PowerCRM tool allows developers to quickly search parcels based on advanced criteria such as acreage size, buildability or topography, and more.
Land Size and Layout:
The size of the land plays a crucial role in determining the capacity and output of a solar farm. Typically, large-scale solar farms require significant land area to accommodate a substantial number of photovoltaic (PV) panels. The size of the solar farm should be determined based on the desired power generation capacity and available sunlight. Additionally, a well-designed layout is essential to maximize energy production. Factors such as panel orientation, spacing, and shading need to be considered to optimize the overall performance of the solar farm.
Land Quality and Topography:
The quality of the land and its topography are critical factors in solar farm development. Flat or gently sloping terrains are preferable for ease of installation and maintenance. Steep slopes can pose challenges in terms of panel installation and access. The land should also be free from obstructions like trees or buildings that could cast shadows on the panels and reduce energy generation. Soil quality is another crucial aspect, as it affects the stability of the mounting structures and the potential for erosion. Conducting thorough site assessments and soil tests is essential to ensure the suitability of the land for solar farm development.
The Best States for Solar Farms
When it comes to sourcing the best locations in the US for solar farm development, California, Texas, North Carolina, Florida, and Arizona emerge as top contenders. These states offer favorable conditions, supportive policies, and a strong commitment to renewable energy. Investing in solar farms in these locations can help meet the growing demand for clean and sustainable power. As the US continues to transition towards a greener future, harnessing the potential of solar energy is crucial for a sustainable and environmentally friendly energy landscape.
California: The Undisputed Leader:
Surprising no one, California stands as the absolute best place to develop solar power. With its abundant sunshine, favorable policies, and proactive approach towards clean energy, California has established itself as a leader in solar energy production. The state boasts numerous large-scale solar farms, including the Solar Star, Topaz Solar Farm, and Ivanpah Solar.
Texas: Harnessing Vast Open Plains:
The open plains of Texas offer an ideal landscape for solar farm development. With plentiful sunlight and vast stretches of land, Texas has great potential for solar energy projects. The state's commitment to renewable energy, coupled with its supportive regulatory environment, has attracted considerable investment in the solar industry.

North Carolina: A Rising Solar Powerhouse:
North Carolina has emerged as a strong contender in the solar energy sector. The state offers a favorable business climate, generous incentives, and a robust renewable energy portfolio. With its significant solar capacity and steady growth in the industry, North Carolina is an attractive choice for solar farm development.
Florida: Sunshine State Embracing Solar Power:
Known for its sunny weather, Florida is making strides in solar energy adoption. The state has favorable policies, such as net metering and tax incentives, that encourage solar development. Florida's commitment to increasing renewable energy generation makes it an excellent location for solar farm projects.
Arizona: A Desert Oasis for Solar Energy:
With its abundant sunlight and desert landscapes, Arizona provides an ideal setting for solar farm development. The state has a strong solar potential and is home to several large-scale solar farms. Arizona's commitment to renewable energy and its supportive policies make it an attractive choice for solar investors.
Assessing the Best Locations for Solar Energy
Solar developers can determine the best locations for solar energy by considering several factors. LandGate’s Solar PowerVal tool allows developers to assess any solar project within minutes, including data about applicable federal and local incentives for solar energy development. Here are a few key considerations:
Solar Irradiance:
Solar irradiance refers to the amount of solar energy available in a specific location. Developers should assess the solar irradiance levels in different regions to identify areas with high levels of sunlight throughout the year. Locations with higher solar irradiance will generally have greater potential for solar energy generation.
Latitude and Orientation:
The latitude of a location affects the angle at which solar panels should be installed to capture maximum sunlight. In the northern hemisphere, solar panels should face true south, while in the southern hemisphere, they should face true north. By aligning panels correctly, developers can optimize energy production.
Proximity to Electric Grid Infrastructure
Solar projects need to be located close to important grid infrastructure in order to reduce cost and electricity loss due to transmission. Projects must be located near a viable point of interconnection whether it be a substation, a transmission line tap, or a distribution line tap. It is also important to consider the available capacity and any upgrade costs that may be associated with interconnection.
Shading and Obstructions:
It is crucial to consider potential shading and obstructions that may affect solar panel efficiency. Trees, buildings, or other structures that cast shadows on the panels can significantly reduce energy generation. Developers should select locations with minimal shading and ensure proper spacing between panels to mitigate any potential obstructions.
Land Availability:
The availability of suitable land is another important factor. Developers should identify large enough parcels of land that can accommodate the desired capacity of the solar farm. Factors such as land ownership, zoning regulations, and accessibility should also be assessed.
Policy and Incentives:
Government policies and incentives play a significant role in determining the viability of solar energy projects. Developers should consider regions with favorable policies, such as feed-in tariffs, tax credits, or renewable energy targets, which can support the economic viability of solar projects.
Locating the Best Places for Solar Energy on a Map
LandGate offers valuable tools that solar developers can utilize to locate and assess the best sites for solar farm development. Here's how they can make use of these tools:
