Product: HOMER Pro 3.11 The HOMER Pro Optimization Plot and Optimization Surface Plot help you understand how your optimization variables affect the overall costs of your system. Once you have calculated results for a HOMER model, you can access these plots by clicking on the Results view and then choosing Graphical from the Tabular/Graphical radi

Product: HOMER Pro 3.11.5 There are a variety of tools in HOMER Pro to help you understand how the components are operated (“dispatched”) to determine the economics. You’ve probably been able to open the detailed Simulation Results by double-clicking on a system in the Optimization Results table. This opens the Detailed Simulation Results window

Product: HOMER Grid 1.1 and HOMER Pro 3.11 This article provides users with tips to make HOMER calculations run faster and explains why some calculations may run slower. In terms of hardware, the most important piece would be the processor speed and the number of cores. For example an i7 processor that has 4 cores, means that it can run four se

Product: HOMER Pro 3.11 HOMER User Tip: Modeling Critical and Priority Loads HOMER Pro’s two distinct electric loads can be used for many different purposes (residential vs. commercial or air conditioning vs. lighting) with different efficiency options and load growth assumptions. But one of the more interesting and little-known application

Product: HOMER Pro Advanced Grid module HOMER Pro’s Advanced Grid module enables users to model unreliable grids. Click on the "Grid" button in the Components ribbon. Under Scheduled Rates, select the "Reliability" tab and for Choose Data Source, choose the radio button for "Enter outage parameters." The green grid on the right is used to model

HOMER Pro version 3.11.4 The power to present modeling results in easy to understand graphs is essential to any project. HOMER Pro and HOMER Grid has a variety of tools to create professional looking graphs for your use. In this tip we will look at

Product: All versions of HOMER Pro HOMER Pro’s Optimizer offers a useful alternative to HOMER’s Search Space. When using the Search Space, HOMER only considers the sizes of components that the user has specified. The Optimizer lets HOMER find the optimal sizes for system components. This is particularly helpful in early stage modeling, when users

Product: All versions of HOMER Pro In HOMER Pro, we often see cost tables with a single row, meaning that the cost is proportional to the size. In the PV cost table below, for example, the costs for 1 kW of capacity (kWp) are $3000 capital, $2500 replacement, and $10/year O&M. For 2 kW, it would be $6000, $5000, and $20/year.
