# Custom solar panels
This guide applies to the [easy-pv.co.uk](https://easy-pv.co.uk/) and [beta.easy-pv.ie](https://beta.easy-pv.ie/) versions of Easy PV. The information provided here may not be accurate for easy-pv.com and easy.pv.ie.
To add a custom panel in Easy PV navigate to **My Components** > **Solar Panels** on the left-side menu or **Components** > **Edit Solar Panels** from the top drop down menu. You will need the **datasheet** from the manufacturer so Easy PV can appropriately perform calculations for inverter sizing and system output. Below you will find guidance on how the information in the datasheet corresponds to the values Easy PV asks for. #### **Creating manufacturer** When adding any custom panel in Easy PV you first need to add a custom manufacturer category which allows you to organise your custom components. The components added will be categorised by their manufacturer when it comes to select them in a project.

This is a list of potential variations for each value required to add a custom panel:**Technical info** | **Variations** |
**Power:** power of the panel at STC in Watts | - Peak Power Watts - Maximum Power Pmax - Power at MPP |
**Isc:** short circuit current of the panel at STC in A | - Short Circuit Current - Short Circuit Current Isc |
**Impp:** maximum power point current of the panel at STC in A | - Maximum Power Current - Current at MPP |
**ΔIsc/°C:** the temperature coefficient of the panel short circuit current | - Temperature Coefficient of Isc |
**Voc:** open circuit voltage of the panel at STC | - Open Circuit Voltage |
**Vmpp:** maximum power point voltage of the panel at STC | - Maximum Power Voltage - Voltage at MPP |
**ΔVoc/°C:** temperature coefficient of the open circuit voltage of the panel | - Temperature Coefficient of Voc |
