4 1 Installation is a plug in of SketchUp. Plugins are one of the most important features in SketchUp. There are thousands of plugins you can install in SketchUp to add new features. So to install you must install first SketchUp (Make or Pro). The installation process is the same of any plug in of SketchUp. You can read about install a plugin in SketchUp here: plugins for google SketchUp/ There are 3 ways to install a plugin: Manually, unzipping downloaded plugin and saving it in Plugins folder. Opening Sketchup and going to Preferences Extensions Install plugin, and selecting downloaded file. Using Extensions Warehouse tool in SketchUp. (Let s you install and uninstall) 1.1 Automatic installation way Download a plugin, store it in your computer, open SketchUp and go to: Windows OS: Window-Preferences-Extensions-Install Extension MAC OS SketchUp-Preferences-Extensions-Install Extension Select the plugin. 1.2 Manual installation way We recommend the manual way because is easy to install and uninstall (only you must delete unzipped files), and you can control the files you copy. Steps: Change the extension of the file from.rbz to.zip. Unzip the file: Store unzipped files in Plugins folder of SketchUp: Windows OS: C:\Users\YOUR USERNAME\AppData\Roaming\SketchUp\SketchUp 2014\SketchUp\Plugins MAC OS Version 2014 and newer: Open a new Finder window, press and hold the Option key on your keyboard, then click Go in the menu bar > Library > Application Support > SketchUp 2014 > SketchUp > Plugins - 4 -

5 1.3 Extension warehouse installation way Extensions warehouse is a web page where you can download a lot of plugins for SketchUp. Open SketchUp and go to Window Extension Warehouse to install any plugin. To be sure that installed plugin is the last version we recommend not use that method and download from directly. 1.4 Update Make a backup of dimension_modules.csv. This file store all sizes of your custom panels. Delete all files and folders Install new version. Above image show the files to delete. 1.5 Uninstall Go to Plugins folder and delete skelion folder and skelion.rb file. Other way is open SketchUP and go to Window Extension Warehouse, look for plugin in Extensions warehouse and click uninstall. 1.6 Write rights needs write rights in plugins folder to write in files like dimension_modules.csv. If you don t have write rights you receive this message and won t start

6 Message of error when Plugins folder doesn t have write rights Read this article about: setting security permissions in SketchUp Write rights in Windows OS Security tab of plugins folder. Go to C:\Program Files (x86)\sketchup (SketchUp 2013)" or C:\Program Files (x86)\google\google SketchUp 8\ (SketchUp 8). Right click on the Plugins folder and selected "Properties". Select the security tab, selected yourself as the "Group or user names:", and allow yourself Full control. Check in General tab that read only is unchecked for all files and folders inside Plugins. General tab of Plugins folder

7 1.6.2 Write rights in MAC OS Right click over Plugins folder and select Get Info. Click the disclosure triangle next to Sharing & Permissions to display permissions for the selected folder. Click the lock and authenticate with an administrator account. Use the menus next to users and groups to add Read & Write permissions to you. When you re finished, close the Info window. Changes are effective immediately. 1.7 Pro version and Free version runs 15 days in pro mode. After that, free version is activated. If you want to use Pro version, you must buy a license in and insert the serial in the web dialog you can watch pushing "About" button in toolbar

8 2 Units In dialogs you can use length units as in SketchUp. You can write 8 m, 8cm, 8mm, 8, 8 (default unit is used). For other units different than length, user must write only the number. Examples: You must write 220, but not 2.2kW. Yo u must can 8cm or 8 m or 8 any SketchUp valid unit. 3 Geolocating model First step in SketchUp is geolocate the model. Go to View toolbars Google. Google Toolbar want. Press this button. "Add Location", to open Google Maps window dialog and grab the area you When you geolocate the model you achieve: Satellite picture (Windows Layers Google Earth Snapshot) 3D mesh of surface. (Windows Layers Google Earth Terrain) Real shadows of geographic position selected for any time of the year.(window Shadows) Google Earth Terrain layer Shadow window Layers window Google Earth Terrain layer Google Earth Snapshot layer - 8 -

9 4 Drawing the building In SketchUp there are several forms to draw the building: Drawing from satellite picture directly. Geo modeling with SketchUp. Exporting 2d or 3d planes from other programs like AutoCAD. 5 's toolbar To activate 's toolbar go to View toolbars. Also you can find all commands in Plugins In pro mode insert button let you also insert panels in non planar surfaces. pro toolbar free toolbar Names of buttons: Surface azimuth and tilt Insert solar components Meteorological data Optimum orientation Sunny area Minimal Shading criterion Erase panels Rotate north Restore north Array view Report Face report JRC PVGYS EUROPE JRC PVGYS AFRICA PVWATS report Project face to mesh Surface report Change UTM model origin Drop PVSYST exporter Export shading derate Relief - 9 -

11 5.1 Rotate north and Restore north In SketchUp true north can point in any direction. You can change true north installing the plugin "Solar North" form Sketchup extensions warehouse. Solar North toolbar use default Y+ axis (green axis) like true north. So you must take into account SketchUp true north (orange axis) must have same direction of Y+axis (green). You can see SketchUp true north clicking. Skechup current version, import 3d mesh and satellite image slightly rotated when you geolocate a model. That is because true north value changes to a value between 0º and 2º. In the picture you can appreciate true north (orange axis) differ 1.74º from green axis. Button "Rotate north" calculations will be right. "Restore north" button let us rotate all model to give true north same direction of Y+. Then rotate model to original position, just in case you want to return. Midi d'ossau Latitude, Longitude:

12 5.2 Surface azimuth and tilt Press the button and select faces to watch his azimuth Ψ and tilt Σ in the opened window. Values will change in the window each time you select a new face. 5.3 Insert solar components button: This button give access to three different web dialogs, in function of the objects selected before press the Selecting and edge and a face: INSERT FOLLOWING AN EDGE Selecting some faces MULTIPLEFACES Selecting 3d mesh: NON PLANAR SURFACE Insert following an edge. To open the web dialog "Insert following an edge" user must select one edge and one face and press the button "insert solar components". Selected edge can be any edge of the face boundary or any edge in same plane of the face. Orientation: Components will follow edge. (You can reverse direction if you want to insert just in the opposite way of default direction.) Component: Component selection has 2 files with some square panels: user/pvmodules.csv > User can store here its own modules. (User folder won't be overwritten in future rleases >5.1.5) database/pvmodules.csv > PV panels database. You can edit user file to add your own modules with any text editor. You must take into acount is a csv file. Excel can change all commas for semicolons if your regional configuration use comma as decimal separator. Change regional configuration to avoid this because only works with commas to separate the values. Also you can use text editor. this tool to insert a solar panel in user/pvmodules.csv file withou edit the file in a You can insert your own designed components. To insert it, you must load into the model using Sketchup windows Components. After in insert dialog, change database to In model

13 Design your own solar component in SketchUp: 1 Draw your component. 2 Make it a component. 3 Make it a component with. 4 Click right button over it, and select save as to save the component in your computer. Before save, component must be oriented in an specific form, because needs to know how to insert it: Z+ axis must be perpendicular to collecting surface Origin will be the point of insertion over the face. If collecting surface is smaller than bounding box then you need to mark it with right button Mark collecting surface. Marking this, will be able to calculate right shadow distances between rows. If collecting surface is equal to bounding box, then this step is not necessary. Collecting surface smaller than bounding box. You can learn more about components in: Right axes situation in component. Loaded components Right axes sitution in component. Square created components

14 Other component parameters: Parameters to insert a component. "Stack components" let us pile up components. With "Rows alignment" you can adjust all components to a grid or let rows to maximize the space. Pitch: Pitch. User can insert his own pitch or use any of the options proposed by. Insert: Pitch

15 You can insert all components at same time in the face with Fill face button or going row by row using Fill in rows. Using this last button, you can click in any point rear the last row inserted. will insert next row mataining the minimum pitch you selected, but if you click in a point with more pitch, then the next row will be inserted in that point Multiple faces Multiple faces dialog You can access to dialog "multiple faces" opening some faces and clicking the button components". ( will use only faces. Other objects of selection will be discarded). "Insert solar Selection of some faces. "Multiple faces" Σr = 0 There are 3 options to insert solar components: Ψ and Σ of component: will insert components in all selected faces. (In coplanar case, will try to follow the tilt of the roof. Σ: Solar component will be inserted following roof tilt. If roof tilt is 0 then program will try to follow any edge of the roof. Σr: Solar component will be inserted following roof tilt If you want coplanar you must insert Σr = 0. If roof tilt is 0 then program will try to follow any edge of the roof Non planar surface "Non planar surface" allows you to insert components in 3d mesh, like curved roofs or solar ground mount systems. To use "Non planar surface" you must follow next steps: Select mesh with main surface and inner surfaces in which no components will be inserted. Boundaries of each surface must be "NO SOFT" and the others must be "SOFT" to let detect surfaces of the mesh. Press button "Insert solar components"

16 "Surface tool" will be activated. Pick with the mouse over a point in the mesh to insert first row. You must select other tool to deactivate "Surface tool". Then, when you click "Non planar surface" a dialog will be opened and we must insert azimuth, tilt, component and times to calculate the pitch. Pitch used between rows will be different and will be the worst of all the components for the times specified by the user. If you want only one hour you must insert the same time twice. If component has "construction points" you can use "surface report" to make a report about position of construction points and Ψ and Σ of selected edge. You can use any type of component, solar panel, solar ground structure... All inserted components will have same azimuth Ψ and same tilt Σ and there aren't shadows between the times inserted in dialog In complex surfaces sometimes you must execute twice the program because rows follow only one direction when are inserted. Components with Ψ 0ºe Σ 30º (180ºconv). Components with Ψ 0ºe Σ 30º (180ºconv)

17 Rules to use "non planar surface": NO HOLES in mesh. Mesh with a hole. Right mesh. All faces must have right orientation. (Use reverse face to fix mesh) Mesh with reversed faces. Right mesh. Boundary of any surfaces must be "NO SOFT". Rest of edges must be "SOFT". Mesh with 3 surfaces and boundaries NO SOFT

18 Select all surfaces, the main surfaces and the others where solar components won't be inserted.. Mesh with all selected. Main surfaces can't share boundary with the others surfaces. Main surface share boundary with other surface. Right mesh. Check shadows. Sometimes last rows or components near the boundaries can be erroneous. 5.4 Meteorological data needs meteorological data to make some calculations like shading derate, or SOF plots. You can choose data from several databases. Satel light databse: Dowload a tsv file from Satel light web page. Select irradiance global and difuse. Time period can be one or several years. tries to make a TMY if you choose the 5 years using RMSD method. Satel light Parameters to make tsv file for

19 5.5 Optimum orientation Surface orientation factor (SOF) is the ratio of annual incident solar radiation for a particular orientation to annual incident solar radiation for an optimally oriented surface. To make a SOF you must select several construction points of a face. Shadows of the model are calculated and effects of morning/afternoon cloudiness and snow cover are also addressed if you are using hourly TMY meteorological data. Increased ground reflectance due to snow cover is not used but have a negligible effect on SOF plots. Anual lapse can be changed using the 8760 hourly array. You can add to selection one face and one edge. Relative tilt versus SOF graph is plotted. This graph shows different relative tilts of a solar panel following the selected edge: Tilting solar panel in one direction Tilting solar panel in the other direction SOF plot with all relative tilts following an edge for a solar panel. (Red one direction, blue the other) Relative tilt versus SOF following an edge

20 5.6 Sunny area Selecting a face you can find out the zone with no shadows at one time or between two times. (If you want only one time, repeat same time twice in dialog.) To improve speed of algorithm you can hide all elements not useful with normal methods of SketchUp: hide geometry, hide layers and cast shadows. Face before use "sunny area" Face after use "sunny area" 5.7 Minimal Shading criterion Select a face and press the button to find out the area that accomplish this rule 5.8 Erase panels First you must make a report, calculating shading derate. Now you can use this feature to hide all panels that have a shading derate less than a percentage you want. Now you must to make again the report to know the number of panels of your system. 5.9 Array mode Clicking this button solar components turn to white. You can select each component and colour it with "Add material" to mark the arrays of your system. Click again to return to normal view Report "Report" button returns the number of components inserted by, and their power. You can copy the report to excel if you want. Data is arranged in 3 forms: By face and solar component model. By groups with same tilt and azimuth and solar component model. By arrays A new layers will be create with numbered faces

21 Layer TX:Face_names active Face report dialog Press this button to open face report window. After this select any face. All the information of the face will be showed in the window. Remember this information is static. If you delete components, you must update model clicking report analysis, PVGYS or PVWATTS JRC PVGYS EUROPE y JRC PVGYS AFRICA With button "PVGYS" or "PVGYS" AFRICA you can find out energy of solar components. links with JRC web sending all the necessary data to the web. PVGYS web is valid only for one tilt and one azimuth, so repeat the process the number of times equal to the groups with same tilt and azimuth of the model. sends the following data: Azimuth Ψ and tilt Σ. Azimuth is transformed automatically to PVGYS convention. (180º north hemisphere convention for the entire world). Technology Group power. Location. You must follow an order closing windows and you can close white window. Location is added automatically but you must click search button. 1. Click calculate 2. Close main window. 3. Repeat the process for each group. You can select and copy the result in Excel PVWATS report With button "PVWATTS" you can find out the energy of SketchUp model in USA. links with NREL web, sending all necessary data. PVWATTS is valid for one azimuth and tilt, so repeat process a number of times equal to groups with same tilt and azimuth in the SketchUp model. sends the following data: Azimuth Ψ and tilt Σ. Azimuth is transformed automatically to convention used by PVWATTS. 360 convention. Group power. Location. You can copy and paste the report in excel

22 5.14 Project face to mesh With button "project face to mesh", you can obtain the face more similar to the mesh below it. Select the face and press the button systems. "project face to mesh". You can use it to make fast layouts of ground mount Face ready to project. Result of face projected Surface report "Surface report" gives information about position of solar components inserted. Component must have "Construction Points" inside Steps to use "Surface report": Hide all elements over and below surface. Select one edge of component and press. The report generated inform about: Coordinates UTM of all "construction point" of each component. Coordinates UTM of projections of "constructions points" over surface, following direction of selected edge. Distance of each points to surface. Azimuth and tilt from selected edge in all components

23 5.16 Change UTM model origin SketchUp origin point (0,0,0) in the real world is the same point that we use to geolocate the model: Window model geolocation. Knowing this correlation we can find out the coordinates of any point of the model in the real world. Surface report use this correlation to calculate the position of some points of the model in real world. If we are working over Google Earth Terrain Layer we must do nothing. But if we are working with a mesh imported from AutoCad or a mesh from a topographer we must set the origin of SketchUp in the right place. To achieve a good correlation between real world and model we must follow the next steps: 1 Know the coordinates of one point of the model. (Latitud, longitude or UTM coordinates). 2 Move all the model, setting this point in SketchUp origin (0,0,0) 3 Geolocate the model with the real position of this point. In window model geolocation we must set latitude and longitude. If we know UTM coordinates instead of latitude and longitude we can use geolocate the model. Change UTM origin to Origin and reference point in different places. Equal origin and reference point 5.17 Drop This tool let you to drop an instance vertically until find a face. It works selecting a group of components inside, or selecting some components. You must hide all elements between the components you want to drop and the mesh. The components will drop until their origin touch the face PVSYST EXPORTER Using this feature you can save in your hard disk a file with Helios 3d format. In PVSYST you can go to Near Shadings Consrtruction Perspective File Import Helios 3d, and select the Helios3d file you saved with. (In current version of PVSYST shadows of objects imported in this way are not calculated)

24 5.19 Export shading derate To save month by hour beam irradiance shading factors. You can use this info to export to System Advisor Model or other software Relief If you need a big mesh of terrain you can use this tool. Before use it, you must geolocate the model component When you make a report, count all components with an attribute. Normal component to component component to normal component This tools let you import components from autocad. Also you can insert components with dome: Draw your own component with dome form. The component must have 2 components inside, one for each panel. Insert with the dome component. Select one instance, convert to normal component with. Enter inside the instance select each panel component and convert to component. Now will count all solar panels and you will be able to make a report. Dome solar panels Construction point This is a feature of SketchUp used to mark points in the model Sun Path Chart This button let us plot sun path chart in cartesian or polar coordenades any day of the year. You can see very similar plots in:

25 5.24 Settings Azimuth convention Web dialog Azimuth convention Select the convention you want and close the web dialog. PVGYS and PVWATTS are external programs to, so when they are opened, azimuth is converted to the convention they use. PVWATTS use 360º convention and PVGYS use 180 conventions in north hemisphere but for the entire world Shading derate test. Algorithm makes a shading test in some points of the solar panel. Here you can add more points to the Report Used to make groups when you have several orientations in a mesh. Angles in report will be averaged About Click to insert pro version serial
