A few days ago, OpenAI released ChatGPT, a bot that talks with humans via cutting-edge artificial intelligence optimised for dialogue. You get a lot of noise when you Google stuff, while this AI thing can go straight to the point (in most cases 😊). I am so excited about what I saw today, so I want to publish my Q&A with AI here.
Q&A Session
How to find the best spots for Utility-scale PV Solar Farms?
Identify locations with high levels of solar radiation, such as areas with clear skies and minimal cloud cover.
Analyze the availability of land suitable for PV solar farm development, including factors such as zoning regulations, availability of grid connections, and access to transmission lines.
Consider the potential for energy generation and cost-effectiveness of PV solar farms in different locations.
Research local and state incentives for renewable energy development, such as tax credits or rebates, to determine potential financial benefits.
Consult with experts in the field of PV solar farm development to assess the feasibility of potential locations and to identify the best spots for PV solar farms.
Engage with local communities and stakeholders to obtain feedback and support for proposed PV solar farm locations.
Conduct thorough environmental assessments and obtain necessary permits to ensure compliance with regulations and minimize impacts on natural habitats and wildlife.
Where can I check the solar radiation for the selected area?
Solar radiation data can be found from various sources, including:
National Renewable Energy Laboratory (NREL) Solar Radiation Data Manual for Buildings
NASA's Surface Meteorology and Solar Energy (SSE) Web Site
National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI) Solar and Water Data
The United States Geological Survey (USGS) National Solar Radiation Database (NSRDB)
Local weather stations and meteorological agencies.
What is a good benchmark of solar radiation?
A good benchmark for solar radiation is a location with an average daily solar radiation of 4-6 kWh/m2. This level of solar radiation is typically sufficient to support efficient PV solar farm operations and provide a good return on investment. However, the optimal level of solar radiation may vary depending on the specific PV solar technology and project design. It is important to consult with experts in the field and conduct detailed assessments to determine the best solar radiation level for a given PV solar farm project.
Is ambient temperature an important factor?
Yes, ambient temperature is an important factor to consider when determining the feasibility of PV solar farm locations. High temperatures can reduce the efficiency of PV solar panels and decrease their overall energy output. Therefore, it is important to identify locations with moderate temperatures that are conducive to efficient PV solar operations. This can be achieved by considering factors such as the altitude and latitude of the location, as well as the local climate and weather patterns. Consultation with experts in the field can help identify the best locations with appropriate ambient temperatures for PV solar farm development.
How the cloud cover affects the solar energy produced? Where can I do this type of analysis?
Cloud cover can significantly impact the amount of solar radiation that reaches the Earth's surface and therefore affect the amount of solar energy produced by PV solar panels. On cloudy days, the amount of solar radiation reaching the PV solar panels can be reduced by up to 80%, resulting in a decrease in solar energy output.
To determine the potential impact of cloud cover on a PV solar farm, it is necessary to analyze historical weather data for the selected location. This data can be obtained from various sources, such as local weather stations or meteorological agencies, and can provide information on the average cloud cover, solar radiation levels, and ambient temperature at the proposed PV solar farm location.
Once this data is collected, it can be used to conduct a detailed analysis of the potential impact of cloud cover on the PV solar farm's energy output. This analysis can be performed using specialized software tools or by consulting with experts in the field of PV solar farm development.
Where can I download the weather data?

Can you provide me with some financial benchmarks for utility-scale projects?
Some financial benchmarks for utility-scale PV solar farm projects in the United States include:
Levelized cost of electricity (LCOE): The levelized cost of electricity is the total cost of generating electricity from a PV solar farm, including the capital costs, operating costs, and financing costs, divided by the total lifetime energy output of the project. In the United States, the average LCOE for utility-scale PV solar farm projects is around $30/MWh.
Internal rate of return (IRR): The internal rate of return is the discount rate that equates the present value of the cash flows from a PV solar farm project with the initial investment. In the United States, the average IRR for utility-scale PV solar farm projects is around 10-12%.
Net present value (NPV): The net present value is the present value of the cash flows from a PV solar farm project, discounted at the required rate of return, minus the initial investment. In the United States, the average NPV for utility-scale PV solar farm projects is around $1-2 million per MW.
These benchmarks are based on average industry data and may vary depending on the specific project and its requirements. It is important to consult with experts and conduct detailed financial analysis to determine the specific financial benchmarks for a PV solar farm project.

Aftertaste
I have been working with utility-scale PV Farms for the last 1.5 years and have done a lot of research on the topic. The ChatGPT answers and their structure is impressive. I would say is frighteningly intelligent. The immediate implication is writing and checking factual information. If something is unclear, paraphrase, clarify, and go digest it for as long as you need, slow thinking human.
It seems like a new era - time to ask the right questions. I remember that the most valuable forums for acquiring knowledge were those with strict moderator rules, where old-timers made you read FAQs and use search at full capacity. This is where my personal culture of asking questions was formed. No fear asking questions anymore because relentless AI chat can handle as much stupidity as we can generate (actually not sure about this). Is it good or bad? Who knows? We will see. The future is exciting!
