Renewables in Ladybug plug in

Hi, I use LB V.1.4 but I can’t find"Renewables" components when I want to model Photovoltaic panels …what is the proplem?

Hi @RadwaEzzat You can check this discussion.

Sorry, but Does this mean that these renewables components have not yet been added to LB plug in v 1.4? if it is true I want to know the latest version that I can download and this component is available in? Thank you

Yes, they’re not in the LBT plugin, though there are similar ways of trying to run those types of renewables studies in LBT. Can I ask what specifically you are trying to model? Is it just estimating the electricity that you would get from PV panels?

Yes exactly, I want to model PV panels and get Power output


Can I ask you what kind of similar method is that?
Is a similar way of estimating the amount of irradiation on the surface?

I hope that the same simulation can be realized in LBT as soon as possible, such as PV simulation performed in the idf file.

Wish you please help me Mr Chris

The Annual Irradaince recipe in the LBT plugin is going to give you the most accurate simulation of hourly solar irradiance out of anything that’s currently offered across legacy or LBT. So that’s what I recommend using if you need high-accuracy hour-by-hour irradiance values to estimate energy harvested by PV. You’d still have to multiply the results by the efficiency of the solar cell and the other factors that account for PV cell temperature, dirt, snow, etc. But the starting irradiance will be more accurate than anything you had in legacy.

I know that the hourly PV cell temperature calculation is particularly tough to do just with native GH components so I’ll try to add a dedicated component that does that at some point. We’ll also eventually add the ability to specify PV in Honeybee EnergyPlus simulations since I know people often want to compare energy harvested with energy consumption in the same simulation. But, for now, that “Annual Irradiance” simulation is the best way to get the irradiance.
