Frequently asked questions

Project Creation

How do I create a project?


There are a couple ways to create a project. Either use the globe to find a site location, use the search bar in the upper left, or upload a KMZ. On the ‘Project Info’ page name your site or use the name that is preassigned. You can also click the blue menu icon in the upper left and click “Create a new project” to start a new project.




How do I search for an existing project?


To search for an existing project click the menu icon in the upper left and use the “Search Existing Projects” search bar. To sort your projects, use the icons listed under the search bar – you can sort by date, project name, or customer. You can also look for projects by going to the home page and just moving the globe to find your project.




Can I move my pin once I create my site?


Once you have created a site and moved on to the Project Information page, you will not be able to move the pin unless you go back and create a new project.




What is "Project Name"?


"Project Name” refers to the overall site location. You can run multiple simulations with various settings for a single project.




When should I use the customer field?


The “Customer” field is useful in applications where you are designing for many customers and need to personalize the projects to the customer.




Which browser is best suited for the platform application?


The Terabase Platform operates most efficiently on Google Chrome.





Location Information

How do I enter location information?


To enter location information use the search bar in the up right hand corner located on the blue tool bar. You can enter an address, GPS coordinates, or upload a KMZ file.




How do I upload a KMZ?


To upload a KMZ click on the menu icon in the upper left hand corner, and click "create new project" then use the "Upload a KMZ" icon next to the search bar to upload your file. Alternatively, use the KMZ icon on the tool bar on the right hand side.




How do I change my weather station?


To change your weather station, go to Step 1 called “Project Info” and click on the blue “Change Station” button next to Weather Station.




Can I upload my own custom weather file?


To upload a custom weather file, click the “Change Station” button next to Weather Station on the Project Info page. In the popup banner click the button on the upper right hand corner that says “Load Customer Weather file”.









Solar Vocabulary

What is GCR?


GCR stands for ground coverage ratio. This describes the ratio of the overall solar module area compared to the overall area of the total area. It is used to describe how much of the area is actually collecting sunlight.




What is DC/AC ratio?


”DC” stands for Direct Current and refers to the DC or PV module capacity installed in a site. “AC” stands for Alternating Current and refers to the inverter nameplate AC capacity installed. The DC/AC ratio is the ratio of DC capacity fed into the inverter AC capacity installed which is typically in the range of 1.20 to 1.40 depending on site conditions. It is an important ratio for optimizing power plant performance and economics.




What is Ground Albedo?


The albedo of a surface is the fraction of the incident sunlight that the surface reflects. Radiation that is not reflected is absorbed by the surface.




What does yield mean?


The term yield is used to describe the total annual energy generated per kWp installed. Specific yield is measured in kWh/kWp.




What does clipping losses mean?


Cliping losses is a term used to describe the loss of energy when the DC power fed into an inverter is more than it can handle and the resulting power is "clipped" and lost.





Running a Simulation

How do I create a simulation?


To create a simulation either load an existing project and click “Add new simulation” or create a new project and click “Add new simulation” to get started.




How do I submit a simulation?


To submit a simulation, you have to enter all the details required in Steps 1-5, and on Step 6 (the checkmark icon), after entering your desired GCR and DC/AC ratio values you will be allowed to submit the simulation.




How long does a simulation take?


The time it takes to run a simulation depends on project size and the complexity of the site geometry. It should not take more than 2 minutes to run a very large scale site.
