Falls from roofs or ladders can result in serious injuries. Additionally, mishandling electrical components during installation poses a risk of electric shock. DIY installers must have the necessary skills and knowledge about working with electricity and heights to ensure safety.

Lack Of Support For Faults Or Warranty Claims

DIY Solar Panel Installation: Is It Feasible And Cost-Effective? Yes, DIY solar panel installation may offer cost savings and control over the process, but it also comes with drawbacks. One major concern is the lack of support for faults or warranty claims.

If there are any issues with your DIY system, you may need access to professional assistance or warranties provided by solar installers. If something goes wrong or malfunctions, you'll be responsible for troubleshooting and repairing it, which can be challenging and time-consuming.

Additionally, you can make warranty claims for faulty equipment or components with professional support. So it's essential to weigh the potential cost savings against these risks before deciding to go ahead with a DIY solar panel installation.

Inability To Claim Certain Incentives

Unfortunately, one of the downsides of DIY solar panel installation is the inability to claim certain incentives. When you hire a professional installer, they have access to various government incentives and rebates that can significantly reduce the upfront cost of your solar system.

However, as a DIY solar consumer, you may not be eligible for these benefits. This means you will need to cover the total cost of equipment and installation without any financial assistance or tax credits. It's essential to consider this aspect when deciding whether a DIY solar panel installation is suitable for you.
