Customer Questions & Answers

What else do I need to install these panels that is NOT included in this kit and what would be my estimated costs for these additional parts?

Asked by: BudgetGirl
This kit includes just the inverter and panels. You will need to select the correct mounting kit that is sold as an accessory through You will also need cables, a combiner box, fuses, conduit, etc. The reason these items are not included in the main product listing is that they are different for each installation depending on the shape of your home and local codes. There is no one-size-fits-all option. Aside from the mounting kit, everything can sourced at a typical electrical supply warehouse. A licensed electrician is required for installation and they provide all these parts which are referred to as Balance Of System. Professional installation costs about $1.50/W or around $5,250 for this kit. That fee includes labor and the cost of permitting. If you contact Grape Solar technical support 877.264.1014 or, we will be able to connect you with an installer in your area.
