Going solar is a smart move—but it’s also a big investment. Like any major home improvement project, it pays to do your homework. Asking the right questions upfront can make the difference between a seamless installation and one full of surprises.
Whether you’re just starting your solar journey or comparing bids from different companies, this guide will help you make an informed decision and avoid costly missteps.
Here are the Top 10 Questions to Ask Any Solar Installer before signing a contract:
⸻
- Are You Licensed, Bonded, and Insured?
Make sure your installer is certified to work in your state and carries the right insurance. This protects you if anything goes wrong during installation.
- How Long Have You Been in Business, and How Many Systems Have You Installed?
Experience matters. A company that’s been around for years and has a strong portfolio is more likely to deliver a high-quality installation—and be there if you need support later.
- Who Designs and Installs the System—Your Team or Subcontractors?
Some solar companies outsource labor. Ask who will actually be on your roof and whether they’re employees or subcontracted crews.
- What Equipment Will You Be Installing, and Why?
Panels and inverters vary in quality and performance. A good installer should walk you through your options and explain why they’ve selected a particular setup for your home.
- What Warranties Are Included?
Make sure you understand the warranties on equipment, installation labor, and system performance. A strong warranty gives you peace of mind for years to come.
- How Will You Handle Permits and Utility Interconnection?
Navigating local regulations and utility paperwork can be complex. Confirm that your installer will take care of all permitting and interconnection requirements.
- What Are the Total Costs, and Are There Any Hidden Fees?
Always ask for an all-in price—and don’t be afraid to ask about potential extra costs like service upgrades or roof repairs.
- Do You Offer Monitoring and Ongoing Service?
Can you check your solar production online or through an app? What happens if there’s a problem later on?
- What Incentives or Rebates Do I Qualify For?
A knowledgeable installer should help you access local, state, and federal incentives—and make sure you don’t miss important deadlines.
- Can I Speak to a Few Local References?
Nothing beats hearing from real customers. Ask for a list of local installations or testimonials to get a better sense of the company’s reputation.
