Your Solar Panel Installation and Repair questions, answered

Answers to commonly asked questions from the experts on HomeGuide.

How much does it cost to install solar panels?

The average cost to install solar panels is $12,600 to $37,800 for a 6 kW to 12 kW system, after subtracting the 30% federal tax credit. Residential solar panels cost $3.00 to $4.50 per watt, including installation. However, the cost of solar panels continues to decrease each year as solar energy becomes more popular.

The cost to convert your house to solar power depends on the type of solar panels, inverter, and equipment, your location, your energy needs, and local labor rates. Labor costs are higher if your home has multiple stories, dormers, skylights, or a steeply pitched roof.

Are solar panels worth it?

Solar panels reduce or eliminate your electric bills, boost your property value, and reduce your carbon footprint. According to the National Renewable Energy Laboratory (NREL), a home's value increases by $20 for every $1 reduction in annual utility bills. This equates to an increase of $10,000 in home value for every $500 in energy savings per year.

Solar panels typically pay for themselves in energy savings in 6 to 10 years. Homeowners in states with above-average electricity costs will recognize the most value. Solar panels work best for homes in sunny areas with southern or southwestern exposure and don't provide as much value in areas that are regularly cloudy or rainy.

How long does it take to install solar panels?

Solar panel installation typically takes 1 to 3 days. However, the total process may take 2 to 6 months and goes through several stages:

  • Designing a system for your home takes 2 to 3 weeks.
  • Permits and inspections take 3 to 9 weeks.
  • Equipment ordering and delivery takes 1 to 4 weeks.
  • Utility connections and formal Permission to Operate (PTO) from the utility company takes 2 to 6 weeks.

How long do solar panels last?

Most solar panels last 25 to 30 years and come with a 25-year warranty.

Can solar panels be installed on a metal roof or flat roof?

Yes, solar panels can be installed on a metal roof or a flat roof. Metal roofs are strong enough to easily support the weight of the solar panel array. Solar panels installed on flat roofs are typically mounted in frames that angle toward the sun.

Does installing solar panels void a roof warranty?

Solar panel installation typically does not void a roof warranty if the racking system and fasteners are installed correctly. However, the warranty may be void if the roof is damaged during the installation. Common issues that will void your roof warranty include:

  • Solar panel installers causing roof damage, liked cracked tiles or shingles
  • Racking system installed without suitable waterproof sealant
  • Racking system is substandard and doesn't include waterproofing features
  • Wrong fasteners used in the installation
  • Installers drill holes in your roof and compromise the roof membrane or decking

How can I hire the best solar panel installer near me?

It's important to choose an experienced solar panel installer who can provide references from past satisfied clients. A reputable installer will perform an on-site evaluation to determine your energy needs. Follow these tips to hire the best installer near you:

  • Look for installers who are members of the Solar Energy Industries Association (SEIA) and certified by the North American Board of Certified Energy Practitioners (NABCEP).
  • Read their reviews on HomeGuide and Google.
  • Get at least three in-person estimates to compare.
  • Discuss your electricity usage and power requirements with the installer to ensure your system is sized correctly.
  • Choose a company that is licensed, insured, bonded, and has been in business 5+ years.
  • Get a detailed estimate, contract, and warranty in writing before the work begins.
  • Avoid companies with the cheapest quotes as quality may suffer.
  • Never pay in full before the project starts. Follow a payment plan instead.

What questions should I ask solar panel installers before hiring?

Ask these questions to help you find the best solar panel company for your project:

  • How long have you been in business?
  • Which certifications or licensing do you have?
  • Can you provide a list of references with contact info?
  • How do you calculate, size, and design the system for my home?
  • Is there room to expand the system later if needed?
  • How much will I save on utility costs each year?
  • Will you assist me in claiming rebates and incentives?
  • What warranties do you provide?
  • If the equipment malfunctions, do you handle the repairs or do I need to contact the manufacturer?
