Can HOMER model a small district system including flow and return heat pipes and all components i.e. pumps, heat exchangers, valves, fittings, instruments, etc.? HOMER is a decision-making tool for early-stage conceptual design. It can help you find the mix of technologies that will achieve the lowest net cost over the project lifetime. You would

Product: HOMER Pro Yes. Just choose Input Report from the System Tab: HOMER will create an HTML-format report summarizing all the relevant inputs, and display it in a browser. From the browser, you can save or print the report, or copy it to the clipboard so that you can paste it into a word processor or spreadsheet program.

Product: HOMER Pro 3.11 Looking at the HOMER application, it has predetermined equipment loaded in the drop down menus. If we were able to obtain equipment specifications for other equipment, can someone plug those in and run the HOMER model? Yes, you can easily add a new component (e.g. PV, wind turbine, generator, battery) or resource (e.g. fu

Product: HOMER Pro How can I export hourly temperature, humidity, solar, and wind data from a model? You'll need to create a simple model with a PV, wind turbine, and a load. You'll want to check "Consider temperature effects" on the "Temperature" tab in the PV menu. Now, once you add these three resources and click "Calculate", the results will i

There are a few methods of exporting the graphics from HOMER Pro to your documents. The method will depend on what the graphic is. Exporting the Sensitivity Results in Graphical form: Method 1 is to simply right click on any of the graphics and select "Export as PNG" as seen below (Figure 1). You can also configure the title, x and y axis labels,

The best way to use HOMER and Carbon? Two scenarios suppose you are carbon capped would you just put in a fuel cap. If you are carbon taxed would you just add cost to fuel. You can limit or penalize emissions if you click the Emissions button under the Project tab. To cap carbon dioxide emissions, click the Carbon dioxide checkbox on the uppe

Product: HOMER Pro HOMER Pro allows you to set the DC bus voltage by defining a number of batteries per string. On the battery input page, choose a battery type and specify the number of batteries per string. HOMER Pro displays the bus voltage, which it calculates by multiplying the battery's nominal voltage by the number of batteries per string. I

Product: HOMER Pro How do I model meters, switches, circuit breakers, charge controllers, transmission lines, or other components in HOMER? HOMER is a powerful economic decision-making tool to aid in conceptual system design. The component definitions are kept as simple as possible, for ease in modeling while maintaining accuracy of results. You

HOMER uses the period "." mark as the decimal marker. The number "one thousand, two hundred, thirty four point five" would be written as "1,234.5". In some locations, on the other hand, the convention is to write this number as "1.234,5". If we mix these two conventions, numbers may be multiplied or divided by many factors of ten. If you are in a c

The faq´s of HOMER say that it is not possible to simulate a bidirectional battery charge controller, and to calculate With the PV costs. my problem is that I already calculated an inverter to the PV costs, and choose an AC output for PV. is it legitime to calculate the battery charger costs as Converter costs? The answer to your question about

I am currently using HOMER to optimize the off-grid residential PV system. I put hourly based electric load profiles by months, chose the size, and other properties of each component(PV, converter, battery). However, I am not sure how I can optimize the system size or capacity of each component automatically. Since I am now putting these numbers by

Does HOMER Pro have a glossary or a definition of terms page? You can find the term definitions of HOMER Pro under the Glossary in the Help manual. To access the Glossary, click on the "Help" tab followed by clicking on the "Help" button. Next, select the Glossary term that you would like a definition for.

Here I am asking rather basic questions on economics. I have attached 2 HOMER files. I want to know the effect of increase in the rate of interest on the overall project economics. From these 2 files it can be seen in the sensitivity results window that with the increase in the rate of interest, the COE increases while NPC decreases. Now, I do not

Product: HOMER Pro To create a new component model in the library, use the "Copy" button. We removed the "Add new" button from the HOMER Pro Library in favor of the "Copy" button. It is better to use "Copy" on an existing component model and modify it as needed. For each component in the user library, all the model parameters are listed and modif

Product: HOMER Pro and HOMER Grid Users often wonder why HOMER provides two different places to enter a component's size: first in the cost table, then in the 'sizes to consider' table. This looks like duplication and it can strike new users as confusing, but in fact this separation can be helpful if you know how to take advantage of it. Each co
