The solar investment tax credit (ITC), commonly known as the solar tax credit, offers home and commercial property owners incentives to install solar and move to renewable energy.

The solar tax credit will allow you to claim 30% of the total cost of this solar system as a credit on your federal tax return. 

*To be eligible for the tax credit, you must own the system and install it at a residence or business that you own in the USA. You must also fill out Form 5695 (Residential) or Form 2468 (Commercial) 

What Type of Solar Panels Are Included?

We only include Tier-1 / Grade A solar panels in our solar kits. They are always monocrystalline and come with at least a 25-year power output warranty. We only source and supply solar panels from reputable brands that have been in business for many years. For more information on your solar panels, click to watch our video.

What Kind of Batteries Are Included?

We almost only include lithium iron phosphate batteries in our solar kits. This is because they are the longest lasting and safest battery option available today. We only source and supply batteries from reputable brands that ideally have US based operations and support teams. We stand behind the batteries we sell and because of that, your lithium batteries will always be covered by a long-term, comprehensive warranty. For more information on your battery bank, click to watch our video.

Does This Kit Come With Setup Instructions?

In addition to guaranteed lifetime customer support, we also provide you with a custom wiring diagram and commissioning guide for setting up your solar kit. Whether you are planning to hire a professional or install it yourself, this information will set you up for success when it comes to getting your solar power system up and running properly. In addition, you’ll also unlock lifetime access to The Solar Hub, where you’ll find instructional videos, articles, troubleshooting guides and tips, so that you can level up your solar knowledge and get the most out of this kit.

Disclaimer: Each solar kit includes solar-specific equipment to get you started, but please keep in mind that you may need to purchase additional items like installation tools, grounding rods/wire, and any AC components you might need. We highly recommend bringing in a certified solar installer or master electrician to help with the installation process to ensure a safe and reliable system that meets all relevant codes and standards. Also, if you purchase a solar kit without solar panels, you will be responsible for ensuring the compatibility and configuration of your solar panel array. Each solar kit includes professionally designed schematics that work within the parameters of each inverter. There are minimum and maximum input voltages with each inverter that you will need to be aware of so that you do not damage your inverter and/or void your warranty.

Off grid living!

The system has been easy so far to assemble and install. One of the 36 solar panels had 3 shifted cells that seem to be off due to manufacturing and had to drill some holes with the structure otherwise all seems perfect.
