As energy bills rise and climate concerns grow, many homeowners are looking for ways to reduce their carbon footprint and monthly expenses. One increasingly popular solution is solar power. For the handy, budget-conscious homeowner, the idea of a DIY solar panel installation might be especially appealing. But is it the right choice for everyone?
Below, we’ll discuss the pros and cons of doing it yourself versus hiring a professional installer so you can make the best decision for your home, budget, and skill level.
What Does DIY Solar Panel Installation Involve?
DIY solar panel installation means planning, purchasing, and installing your solar energy system without the help of a licensed solar installer. This could be anything from a small off-grid solar kit for a shed or RV, to a full-blown solar array for your roof.
It involves more than just mounting panels on your roof. You’ll need to:
- Design the system (calculate your energy needs, choose components, etc.)
- Purchase the right solar panels, inverters, racking systems, and batteries (if needed)
- Mount and wire the system safely
- Ensure the system complies with local building codes
- Apply for permits and schedule inspections (in most areas)
- Connect the system to the electrical grid (if applicable)
If you’re comfortable with tools, electrical work, and have time to spare, this route can offer significant savings. But it also carries a fair number of risks, including potential safety hazards, challenges with permitting and inspections, the possibility of voiding warranties, and the risk of costly installation errors.
The Pros of DIY Solar Panel Installation
- Cost Savings: The biggest reason people choose DIY is cost. Professional solar installations typically cost between $10,000 and $25,000, depending on the size of the system. By cutting out labor costs, DIYers can save thousands.
- Total Control: You can choose every part of your system from the panels to the inverter to the layout. You also get to work at your own pace and on your schedule.
- A Learning Opportunity: Installing your system can be a valuable experience. DIY might be the way to go if you enjoy hands-on projects and want to deeply understand how your energy system works.
- Great for Small or Off-Grid Projects: DIY solar is ideal for small-scale systems, such as powering a tiny home, cabin, shed, or RV. Professional installers often won’t take on jobs that small.
The Cons of DIY Solar Panel Installation
- It’s Not Easy: Designing and installing a safe, efficient solar power system is complex. It requires electrical knowledge, roof work, and a good understanding of energy systems.
- Mistakes Can Be Costly: A poorly designed or incorrectly installed system can reduce performance, pose fire risks, or damage your roof. These mistakes can be expensive to fix.
- Limited or No Warranty: Many panel and inverter manufacturers won’t honor warranties unless a certified professional installs the system. If something goes wrong, you may be on your own.
- Permitting and Paperwork: Getting local permits, passing inspections, and applying for net metering or incentives can be a headache without professional help.
- Time Commitment: DIY installation isn’t a weekend project. Depending on your experience and availability, it can take weeks or even months.
When to Consider Hiring a Professional
While DIY solar can be rewarding and cost-effective, it’s not the right fit for everyone. Here are some scenarios where hiring a professional installer makes more sense:
- You want to install a grid-tied, whole-home system
- Your roof is complex, steep, or in poor condition
- You want to qualify for manufacturer warranties
- You need help with permits and paperwork
- You want access to state or federal rebates that require professional installation
The Pros of Hiring a Pro
- Expertise and Experience: Solar installers know how to design efficient systems, safely handle electrical work, and ensure everything is up to code.
- Warranty and Support: Professionally installed systems often come with long-term warranties on equipment and labor. Some companies even offer performance guarantees.
- Faster Installation: A professional crew can usually complete an installation in a few days, while DIY projects often take weeks.
- Help with Incentives: Installers often handle the paperwork for state and federal incentives, net metering applications, and permits.
The Cons of Hiring a Pro
- Higher Costs: Labor isn’t cheap, and professional installers have overhead costs. Expect to pay 20-40% more than if you did it yourself.
- Less Flexibility: Some companies may only offer certain brands or limit design options.
- Sales Pressure: Not all installers operate this way, but some use high-pressure sales tactics or try to upsell unnecessary equipment.
Cost Comparison: DIY vs. Professional
A basic DIY solar panel system for a small home might cost between $6,000 and $10,000 in materials. A professionally installed system of the same size could run $15,000 to $20,000. However, pros often have access to better financing and may help you qualify for local rebates.
While DIY can save money upfront, professional installations may provide better long-term value through warranties, efficiency, and support.
Questions to Ask Before You Decide
- Do you have experience with electrical or roofing work?
- Are you comfortable working at heights and using power tools?
- Do you understand how to design a system to meet your energy needs?
- Can you commit the time needed for research, installation, and inspections?
- Will your DIY system be eligible for warranties and incentives?
Hybrid Options: The Best of Both Worlds
Some homeowners take a middle path: they buy the equipment themselves and hire a licensed electrician to help with installation. Others use consulting services or hire contractors for parts of the job (like mounting the panels).
This can save money while reducing the risk of costly errors.
Should You DIY Your Solar Panel Installation?
DIY solar panel installation can be rewarding if you have the time, skills, and patience. It offers cost savings, control, and a chance to learn something new. But it also comes with risks—including safety concerns, possible code violations, and the loss of warranty protection.
Hiring a professional, on the other hand, ensures a smooth process and long-term support, albeit at a higher price.
Ultimately, the right choice depends on your specific situation. DIY might be the perfect fit if you’re handy and working on a small-scale project. But for whole-home systems or anyone unsure of their abilities, hiring a pro may be the wiser long-term investment.
No matter which path you choose, installing solar panels is a big step toward reducing your carbon footprint and taking control of your energy future.
