Solar Exposure: What Role Does GIS Play in Measuring Solar Radiation?

With the increasing levels of global warming and pollution, people are now more concerned about green and sustainable appliances. The conventional energy production techniques have been gaining immense popularity now that the political dealers are asking people to switch to the appliances and tools that help reduce the global warming effect.

Nowadays, the focus of the environmentalists and researchers is on deploying the CSP, as well as, PV systems effectively. The goal is to come up with effective planning and design that can reduce the carbon footprint of people in the environment while saving the world from the hazardous impact of UV radiation. That’s where the GIS (geographic information system) comes into the picture. The technology combined with the remote sensing tools has been used extensively for solar power system design and implementation.

Solar Radiation Map and the GIS Tools

The technology is widely used alongside certain analytical models to evaluate the geographical patterns in a clear and concise way. However, when it comes to installing the PV and CSP units, the most crucial factor that people take into consideration is solar radiation. It has become more important, now than ever, to figure out the areas that receive excess solar exposure. For any kind of location-specific research, there is no better tool than GIS.

The main purpose of using GIS in the sites is for measuring solar radiation, i.e. how much the area is exposed to sun radiation and what impact does it have on the particular land. The solar radiation map, which can be discovered with the help of GIS tools, can also be used to visualize the information about the solar resources. It is important to note that not every study conducted using geo-spatial technology is used to conduct solar radiation mapping, but these are commonly used for determining the existing solar radiation maps and using them for measuring the sunshine hours per year for a specific area.

How Does it Help?

The solar resource map is your ideal tool to collect detailed information about solar exposure in a particular area and other basic information. The power production, potential, and economic effects are a few such factors that you can easily measure with the help of a solar resource map. The biggest advantage of using GIS for solar exposure is that it helps you assess the radiation levels at different locations and varying times without the requirement for any advanced measurement equipment.

Not only does it save you the cost of investing in the equipment for radiation measurement, but it is one of the cost-effective techniques that has been gaining a lot of popularity lately. Since some nations have imposed strict restrictions on the number of solar radiations in the state for recording the radiations, there is only little chance of improving the radiation mapping. If it were not because of the GIS applications, it wouldn’t be possible for people to determine the accuracy of the solar exposure and radiation results.
