While the Tesla Solar Roof is one of the more expensive options on the market, the solar panels are more affordable. Tesla also offers a price-match guarantee, which promises to meet a competitor’s price on eligible solar systems. If you go with Tesla, you’ll have fewer choices when it comes to the components in your solar system. However, the popular Powerwall 3 is only available through Tesla. If you’re hoping for a variety of non-Tesla products, your choices will be limited with this installer.
What to look for when choosing a solar company
When comparing solar installers, there are several factors that set “good” companies apart from ones that might not be the right fit for your home. Consider the following factors when comparing installers.
Solar system cost
Unsurprisingly, the cost of solar panels is an important factor to keep in mind and will differ between installers due to soft costs like installation and labor. According to the Lawrence Berkeley National Laboratory (a Department of Energy Office of Science laboratory), the average cost of a solar array in the US is $31,558, or $3.67 per watt for an 8.6 kilowatt system. Tax credits and solar incentives can help make solar panels more affordable.
You probably won’t find a price tag listed on installers’ websites because the cost of solar depends on factors like system size (which correlates with your annual energy consumption), your location and additional components. Instead, you’ll need to reach out to installers to get a quote for your home. Some installer websites offer an instant quote with a few basic pieces of information (for example, your average energy usage), while others may ask for your contact information and reach out directly.
Financing options
The cost of solar panels is substantial, even though solar prices have decreased significantly in the last decade. While some residents are able to purchase solar panels upfront in cash, that isn’t a feasible option for everyone. Most solar installers offer financing options to lower the initial cost of solar.
If you don’t have the capital to purchase your system outright, you can take out a solar loan. Personal loans, home equity loans and FHA 203(k) loans are among some of the financing options residents can choose. Some state solar incentives include low-interest loans with favorable terms. While solar loans come with interest rates and monthly payments, you will own the system and qualify for solar tax incentives.
Another option is a solar lease or power purchase agreement (PPA). The installer retains ownership of the system with these options, but it is installed on your roof and powers your home. Solar leases and PPAs are the cheapest upfront option and you only pay a monthly rate to lease the system or a set price per kWh of generated electricity. Another benefit is you won’t be on the hook for maintenance or repairs — the solar company is responsible because it retains ownership. However, you won’t own the system or qualify for tax credits and other incentives.
Warranties
Warranty terms will vary by installer but are important to review before you sign a contract. Installers should be upfront about their warranty terms and answer any questions you have about what is covered, the length of the warranty and any extensions they offer.
Most installers offer a few warranties on solar systems. Common types of warranties include:
- Manufacturer warranties or product warranties: Offered by the product manufacturer instead of the installer, manufacturer warranties cover product defects or damage. Many installers guarantee that the products used in solar projects have long-term warranties. Panels, inverters, batteries and racking and mounting equipment come with manufacturer warranties. The typical warranty terms depend on the product, with most panel warranties varying between 20 and 25 years. Batteries and inverters usually have shorter lifespans (and thus shorter warranties), typically around 10 and 12 years.
- Performance warranties: Solar installers typically guarantee that your solar system will perform at a specific level of efficiency for a set amount of time. The industry average is a performance warranty of 90 percent capacity at 10 years and 80 percent capacity at 25 years.
- Quality-of-work warranties: These warranties guarantee that the installation is high-quality and meets local requirements. The installer will ensure there isn’t damage to your property (like your roof) during installation. Quality-of-work warranties typically vary the most between installers. Ask any installer you’re considering about the specifics of this warranty.
Consumer ratings and reviews
There’s no shortage of customer ratings and reviews available for solar installers. As you research your options, you can find reviews and testimonials from past customers, which may help you narrow down your choices. Sites like TrustPilot, the Better Business Bureau (BBB) or Yelp can help you find consumer reviews and complaints for installers.
Solar incentives in your state
You can apply for solar tax credits and incentives at the federal, state or local levels. The Residential Clean Energy Credit is a federal tax credit allowing solar panel owners to claim 30 percent of the cost of their system as a credit when they file their income tax returns.
State and local solar incentives vary based on where you live, but you can combine these incentives with the federal tax credit. The Database of State Incentives for Renewables and Efficiency (DSIRE) offers a comprehensive list of solar incentives by state. While installers don’t have any control over your incentive eligibility, understanding which solar incentives you qualify for can help you better estimate the installed cost of a solar array for your home.
