What Should You Know Before Hiring a Solar Company?
Choosing to install solar is a major home improvement and a long-term financial decision. It’s important to remember that hiring a solar company is about more than the appearance of the panels on your roof. The right company will help determine how accurately your system is designed, how smoothly the project moves through permitting and utility approval, and what kind of support you receive years after installation.
That is why hiring a solar company should involve more than looking for the lowest price or the biggest promised savings. Before signing a contract, take the time to understand how each company evaluates your home, calculates its recommendations and supports the systems it installs.
Here are some of the most important things to consider.
Does the Company Start With Your Actual Energy Use?
A solar proposal should be designed around your household, not built from a generic package.
An experienced solar company will review your historical electricity usage, typically using the information available on your utility bills. It should also ask whether your energy needs are likely to change. An electric vehicle, pool pump, electric water heater, electric heating system or planned home addition could all affect how much power your household uses in the future.
The company should also evaluate the physical characteristics of your property, including:
- Roof direction and pitch
- Tree cover and shading
- Available installation space
- Roof condition and remaining service life
- The potential for a rooftop or ground-mounted system
Even two identical houses can require very different solar systems because the families living in them use electricity differently. If an installer recommends a system before closely reviewing your usage and property, ask how that recommendation was calculated.
Will the Company Tell You When Solar Is Not the Right Fit?
Solar can be a valuable investment, but it is not automatically the right choice for every homeowner or every property.
A trustworthy company should be willing to discuss the factors that could make solar less practical. Heavy shade, limited installation space, an aging roof or plans to move soon could change the financial picture. The goal should be to determine whether solar makes sense for your circumstances — not simply to close a sale.
Look for a company that is willing to do the math with you and explain the assumptions behind its projections. You should understand how your current utility costs compare with the estimated cost and benefits of the proposed system.
Can You Compare Buying and Leasing?
Before hiring a solar company, keep in mind that solar ownership and solar leasing can both be viable options. However, they serve different goals.
Purchasing a system may offer greater long-term savings for homeowners who plan to remain in their homes for many years. Leasing may reduce the upfront expense and create more immediate monthly savings. However, a lease can also affect what happens when the property is sold, since a buyer may need to assume the agreement or the homeowner may need to follow other terms outlined in the contract.
A solar company should explain both options clearly, including:
- Upfront and ongoing costs
- Estimated monthly savings
- Long-term financial return
- Financing or lease terms
- Warranty and maintenance responsibilities
- What happens if you sell the home
Be cautious if a salesperson pushes one option without first learning about your budget, goals and expected time in the home.
How Realistic Are the Production and Savings Estimates?
Solar panels do not produce the same amount of electricity every day. Production changes with the season, weather, roof orientation, shade and other site-specific conditions.
A well-prepared proposal should use your annual electricity consumption and account for the expected performance of the proposed array. Ask what data the company uses to estimate production and whether the projection considers long-term weather patterns—not just ideal sunny conditions.
You should also receive a clear explanation of what solar can and cannot remove from your electric bill. Even when a system produces enough electricity to offset much of a household’s annual usage, certain utility charges may remain.
No installer can guarantee the weather or future utility rates. What it can do is show its work, use reasonable assumptions and help you understand the range of possible outcomes.
Has the Roof Been Properly Evaluated?
Solar panels may remain in service for decades, so the roof beneath them matters.
Installing panels on a roof that will need replacement in the near future can create an avoidable expense. The panels may have to be removed before the roofing work and reinstalled afterward. Before moving forward, ask whether the solar company will evaluate the roof’s age, condition and expected remaining life.
There is a real advantage to working with a team that understands both roofing and solar. If a roof replacement is needed, the two projects can be coordinated before the panels are installed. You should also ask who is responsible if a leak develops near an attachment point and what roof-related protection is included in the workmanship warranty.
Who Actually Handles the Project?
Solar installation includes much more than mounting panels. Depending on the project and jurisdiction, the process may involve:
- System design
- Electrical engineering
- Structural engineering
- Local permits
- Installation and electrical connections
- City or county inspections
- Utility interconnection
- Incentive documentation
- Final permission to operate
Ask which parts of the process the solar company handles directly and which are subcontracted. Find out who will keep you informed, who you should contact with questions and what could affect the timeline.
The physical installation may be completed before the system can be turned on. Final activation often depends on inspections and utility approval, so be wary of anyone who promises an exact completion date without acknowledging those outside steps.
How Will You Monitor the System?
Once your system is operating, you should have a practical way to see how it is performing.
Solar Panther generally recommends microinverter-based systems that allow homeowners to monitor production at the individual-panel level. This makes it easier to identify a panel or inverter that is not performing as expected. It can also keep one component problem from affecting a larger section of the system.
Ask a potential installer:
- What monitoring platform will I use?
- Can I view individual-panel performance?
- Will your team also monitor the system?
- Who helps if the monitoring connection is lost?
- What happens if a panel or inverter underperforms?
Monitoring should not be treated as an afterthought. It is one of the main ways you and the service team can confirm that the system continues to do its job.
What Happens After Installation?
The relationship with a solar company should not end when the panels are activated.
Ask who will respond if the system stops producing, an inverter fails, the monitoring platform disconnects or you need help with a manufacturer warranty. Find out what the company’s workmanship warranty covers, how long labor is included and whether the warranty transfers if you sell the home.
It is also worth asking whether the company services systems it did not install. Solar homeowners across the country have been left with “orphaned” systems after an installer closed, left the market or stopped responding. Manufacturer coverage may still exist, but homeowners often need a qualified local company to diagnose the problem, coordinate replacement components and complete the labor.
A company’s local presence, service capabilities and history can be just as important as the equipment brands it offers.
Questions to Ask Before Signing a Solar Contract
Before hiring a solar company, ask each company:
- How did you determine the recommended system size?
- What assumptions are included in the production and savings estimates?
- Have you evaluated the condition of my roof?
- What are the advantages and disadvantages of purchasing versus leasing?
- Who completes the design, engineering, permitting and installation?
- What is the estimated timeline, and which steps depend on inspectors or the utility?
- How will I monitor the system after installation?
- Who do I call if the system underperforms?
- What do the workmanship and manufacturer warranties cover?
- Will your company be available to service the system in the years ahead?
Choose a Solar Company for the Long Term
The right solar company should give you more than an attractive proposal. It should give you confidence in the system design, the financial assumptions, the installation process and the support available after the project is complete.
