Wind Load on Solar Panels Analysis Spreadsheet to BRE Digest 489

 

 

Wind Load on Solar Panels Analysis Spreadsheet is very much useful for setting up Solar Panels on any roof.

 

This estimating spreadsheet estimates necessary ballast weight / fixings forces / roof loads from wind functioning on Solar Panels (also known as solar modules, photovoltaic modules, photovoltaic panels or PV modules) for checking the feasibility of installing solar panels. The design is adhered to BRE Digest 489. The spreadsheets supports Microsoft Windows Excel version 2007 to 2016.

 

This simplified spreadsheet offers automatic calculations. There is a pop up containing UK & Ireland map to find out the wind pressures on projected Solar Panels. So it is very simple for anybody to apply this spreadsheet for working out the necessary ballast weight.

 

The spreadsheet focuses on the following types of Solar Panels:

 

Photovoltaic modules with ballast: For this type of modules, there is no need for any fixings into present roof structure as well as penetrating current roof membrane. It offers trouble-free processes for post-installing Photovoltaic arrays. The spreadsheet estimates ballast weight necessary to stop uplift, sliding and overturning.

Photovoltaic modules fixed to flat or pitched roof: These are used to provide support to PV modules by attaching directly to loadbearing elements inside the roof structure. To deal with this situation, it is suggested to estimate fixing forces retaining a PV module and therefore giving loads on a supporting roof. All these estimates can be made through this spreadsheet.

This construction spreadsheet offers the following functionalities :-

 

- A coincise and easy to read output (all on a single page);
- Includes three PV classes:
1) PV modules mounted on or above pitched roofs;
2) PV stands mounted on flat roofs - free standing (with ballast);
3) PV stands mounted on flat roofs - mechanically fixed;
