    Steps for Solar Panel Installation

    By installing a home solar power system, you can reduce your dependence on traditional utility companies, offsetting the majority (or entirety) of your monthly energy bills. Plus, it offers a tangible method to curb your environmental footprint, making for cleaner, healthier communities.

    Somewhat counterintuitively, the majority of what determines a successful solar project has little to do with the installation itself. Before getting into how to install solar panels, there are a couple of nuances to note off the bat. First, installing solar panels requires thorough knowledge of solar technology, design and engineering.

    In other words, the average person will likely want to avoid a DIY solar panel installation and leave the process to professional local installers. A properly designed PV system will provide far more savings on the backend than most DIY installations will save on the front. The second thing to consider is that solar panel installation won’t happen overnight.

    Even after you choose the best solar panels for the job, there are a few vital steps in the installation process essential for ensuring a reliable, effective and efficient renewable energy system. Here are the basic steps of solar panel installation:


    SunPower designs and installs industry-leading residential solar and storage solutions across all 50 states. With a storied history of innovation dating back to 1985, no other company on this list can match SunPower’s experience and expertise.

    SunPower earns its position as the top national installer on our list for a handful of reasons: It installs the most efficient solar technology on the residential market, offers the most expansive service area and backs its installations with a warranty well above the industry standard. All the while, SunPower pioneers sustainability efforts within the industry.

    If that weren’t enough, SunPower systems come packaged with products all manufactured in-house by its sister company, Maxeon. This means that your panels, solar cells, inverters, battery and EV chargers are designed to work together and are all covered under the same warranty.

    SunPower’s biggest downside? Its high-efficiency panels are considerably more expensive than most of its competitors’ products. However, its powerful panels are workhorses that make up for the initial cost with more backend production (think about this like spending more money for a car that gets more miles per gallon).

    Blue Raven Solar

    We like Blue Raven Solar because it understands that, for most homeowners, the cost of solar presents the biggest barrier to entry.

    For that reason, Blue Raven Solar developed an innovative solar financing plan that offers in-house, flexible, zero-money-down options. The results speak for themselves, as Blue Raven Solar is now one of the fastest-growing solar companies in the nation and was recently acquired by SunPower. Its BluePower Plus plan (exclusive to Blue Raven) mimics the flexible structure of a lease while still providing the greatest benefits of owning your system.

    Eligible homeowners enjoy 18 months of solar power before having to pay their first bill. When coupled with the federal solar investment tax credit (ITC), the initial energy savings can offset more than a third of the overall cost of a system before requiring a dollar down.

    In contrast, other installers can only offer similar financing through solar leases, PPAs or third-party providers (such as Mosaic or Sunlight). Third-party loan providers can complicate the process, while opting for a loan or PPA will disqualify you from some of solar’s biggest benefits (additional property value, federal solar tax credit and local solar incentives).

    1) Complete a Site Survey With an Engineer

    Once you choose the best solar installation company for your home and sign a contract, the company will send an engineer to your home to evaluate your current electrical system, ensuring everything is compatible with your intended solar panel system design.

    This engineer may be an employee of the solar company or an independent contractor. Be aware that if you have an old and outdated electrical system, the engineer may tell you that it needs to be upgraded or replaced. This is generally an indication that your new solar energy system will require more amps than what your current electrical system can accommodate.

    In addition to checking out your electrical system, the engineer will also want to inspect your roof. They’ll need to ensure it is structurally sound and able to support the weight of solar paneling. Also, the engineer will be able to tell you if you need a specialized mounting system, such as for a flat roof.

    A solar energy system will only perform as well as it’s designed, so hiring a trustworthy solar engineer is one of the most important steps in the process. Still looking for an installation company? Click here to get connected with a solar installer in your area and receive a free quote.

    2) Secure the Right Permits

    Before your solar panel installation, you’ll have a few bureaucratic hoops to jump through. Specifically, you’ll need to obtain all the right permits and documentation to ensure your solar panel installation is legal, meeting all local safety and zoning requirements.

    You wouldn’t believe the headaches that can accompany an installation carried out before permits are issued. This step may sound intimidating, but here’s the good news: While there is plenty of paperwork associated with installing solar panels, the majority of it is handled by your solar company.

    You may not have to do much at all beyond lending a signature here and there, but it’s still important to have some sense of what’s happening behind the scenes. Here’s what your solar installer will file for:

    • Local electrical and/or building permits on your behalf
    • Interconnection agreement with your local utility (in other words, permission from your utility to install solar and enroll in net metering programs)
    • Applications for state or federal incentive programs that curb the upfront cost of solar panels

    By completing this paperwork, you can potentially secure rebates, tax credits or other financial assistance to offset installation costs. It will take your solar installer some time to submit all the paperwork, and even longer for governmental bodies to process all the information — sometimes several weeks or more.

    It’s not a bad idea to follow up and get updates every few days, just to make sure the process is still moving forward smoothly. Solar companies are busy with business, and the squeaky wheel gets the grease.

    Benefits of a Residential Solar System

    There are many benefits to installing a solar system on your home, but the most important one is reducing your long-term expenditure on electricity.

    By adding solar panels to your home, you can cut your electric costs by up to 100%. This can save you hundreds of dollars per month and thousands over the course of a year or more.

    install, solar, panels, guide

    Most residential systems see a return on investment within 10 years. Use the chart to estimate your cost savings by going solar.

    This chart shows the electric bill cost and savings with solar over time. Actual savings will be dependent on the total cost to install the solar system as well as any incentives you may receive.

    The other benefits to installing a solar system are:

    • You can earn a substantial tax credit.
    • Your solar system can extend the life of your roof by protecting it from the elements (sun, snow, wind, or rain) and keep your home cooler in the summer by absorbing the heat from the sun.
    • They have very little maintenance aside from making sure they aren’t covered by leaves or debris.
    • You will typically see an increase of around 5% to your total home value.

    Warranties for Residential Solar Panels

    A modern solar panel system that’s maintained can provide power for over 25 years without any major maintenance or repairs.

    The solar systems we install here at Peninsula Solar all have a 25 to 30-year manufacturer warranty.

    Many of the solar systems we install for our customers outlive the warranty because of the quality of our installation and extra care we take with every system.

    Home Solar Panel Mounting Locations

    A trustworthy solar company will walk you through the best installation options and mounting locations for your home. The two most common solar mounting locations are on your roof or on the ground near your residence.

    A solar mounting system, sometimes called a solar racking system, is the component that secures solar panels to your roof or the ground and holds them in place.

    Before you install, you should research both types of mounting locations and talk to your solar installer to help make the right decision for your needs.

    Roof Mounted Solar Systems

    A roof-mounted system is the most common way many homeowners install solar panels as it’s aesthetically pleasing, helps protect your roof, and your roof often gets the most sun throughout the day.

    These types of systems are generally maintenance-free, but you may have to brush off some snow periodically if you live in snowier areas.

    Ground Mounted Solar Systems

    A ground-mounted system is often a good alternative to roof mounting if your roof is too small, has awkward pitches, or is covered mostly in shade throughout the day.

    This type of installation can benefit homeowners in that it will give them a lot of flexibility as to where the solar panels are installed. This allows them to have more control over the aesthetics and allows them to place the panels where they can be the most effective.

    The biggest advantage to a ground-mounted solar system is that, depending on the installation, the solar panels can adjust their angle throughout the day to capture more sunlight.

    Cost to Install a Residential Solar System

    The total cost of your solar system will come down to how much electricity you use. The typical Michigan resident will need a 6-12kW solar system.

    Before any final quote is given, the team at Peninsula Solar will use solar modeling software to determine the correct system size for your home.

    Even though the cost may seem high at first glance, there are major incentives and tax breaks that help lower the initial cost of financing a solar system. When you pair these incentives with the immediate savings on your electric bill, you will find significant long-term savings.

    Solar Analysis tool can help customers determine if installing a PV system makes sense for them. The tool helps you evaluate all of your solar options – whether to rent or own – so that you can determine if a PV system will meet your financial and sustainable goals. This tool estimates the upfront and long-term costs, the size of the system needed and the payback period for your residence.

    Payback Period

    The actual payback period for investing in a PV system depends on your energy usage, system size, PV technology, tax credits available, installed system cost, and electric rate changes, among other factors. Any payback projection should reflect TEP’s history of stable electric rates, which have increased less than 1 percent per year, on average, over the past two decades.

    Use TEP’s Solar Analysis tool to estimate your payback period or follow these steps:

    • Calculate your system cost after any federal and state tax credits. Check with a tax professional to verify if you are eligible for these credits.
    • Estimate the amount of electricity your system will produce, which is the amount of energy you won’t buy from TEP. This estimate is calculated by multiplying your system size in kilowatts by 1,900.
    • Multiply your annual system production by your electricity rate. This is your annual savings.
    • Divide your system cost – calculated in step 1 – by your annual savings – calculated in step 3 to get the number of years for your payback period.

    Choosing a Solar Company

    It is critical for customers to choose an experienced, reputable solar company that will meet their needs and expectations. Here are some helpful tips for selecting a solar company:

    • Only hire a licensed contractor qualified to do the project. Solar installers must be licensed by the Arizona Registrar of Contractors (AZROC) and possess an Arizona business license that is active and in good standing.
    • Verify the company’s license status by calling 877-692-9762 or visiting the AZROC website.
    • Check to see if the installer is bonded and insured and ask for proof.
    • Use a local installer, if possible. Tucson area installers are familiar with TEP’s requirements and the application process to help ensure project approval and a successful installation.
    • Obtain detailed proposals and estimates from several installers and meet with each of them. Prices, project specifications and warranties vary significantly. Compare each of the proposals to make sure the system will meet your goals and expectations.
    • Check references. Request at least three (3) references from customers whose projects are similar to yours. Consider the company’s experience and find out if they have any unresolved complaints, judgments or liens. Check their Better Business Bureau
    • Get everything in writing. Any material changes to the system design, performance, equipment or estimate should be documented in writing.

    Read all documents carefully before signing. You need to understand the terms and conditions before you sign. This helps prevents disagreements during and after installation. TEP advises against signing an agreement or making payments on leased systems until a DG meter is installed and a Permission to Operate is issued.

    Questions to ask solar companies:

    • Are you licensed, insured and bonded? Can you provide proof?
    • How many other PV systems have you installed that are similar to mine?
    • Can you provide several references?
    • How much energy will my system produce?
    • What will be my cost savings by having solar and what is the estimated payback period?
    • What are the benefits of purchasing rather than leasing?
    • Can the contract be renegotiated and under what circumstances?
    • Is the contract transferrable to new owners if we sell our home?
    • How long will the equipment last before it needs to be replaced?
    • What are the warranties on the equipment, and can I purchase extended warranties?
    • Should the age and condition of my roof affect my decision?

    Selecting a TOU Pricing Plan

    Solar customers may choose from any of our time-of-use (TOU) pricing plans. These plans can reduce your energy bills if you avoid using a lot of energy or operating several large appliances during times of peak demand. For the greatest cost savings, learn to shift your energy usage to off-peak hours, such as mid-day or later in the evening. Customers on TOU plans should reduce energy usage from 3-7 p.m. during the summer and from 6-9 a.m. and 6-9 p.m. in the winter.

    Customers with PV systems sometimes make the mistake of actually using more energy and could see their TEP bills increase. It is important to remain as energy efficient as possible and continue to make every-saving upgrades even after a PV system is installed to keep energy costs low.

    Billing Credits

    Even after you install your PV system, you will still be connected to TEP’s grid and will rely on us to provide safe, reliable power when the sun isn’t shining and your system isn’t generating electricity. Even if you have stored energy from a battery system, it may not meet your power needs. That means you will still get a bill from TEP every month, although it should be lower if you keep your energy usage in check.

    All TEP customers, including those with solar systems, have monthly service charges that cover our costs associated with operating and maintaining our electrical grid.

    Excess Energy Credits

    Once your PV system is installed, TEP will replace your existing meter with billing and production meters to measure your energy usage and the amount of energy your system exports to our grid. The excess energy and credits will appear as “KBH” – kilowatt banked hours – on your monthly TEP bill.

    The buyback rate for excess, unused energy is specified in TEP’s Rider-14 Resource Comparison Proxy (RCP) Export Rate. Customers’ bill credit is based on the RCP rate in effect when their interconnection application was submitted. This rate is fixed for 10 years.

    After the initial 10-year period, the bill credit is based on the current export purchase rate, and may change from year to year. The RCP rate for new applications received before Oct. 1, 2022, is adjusted each year.

    Each month if the customer’s RCP credit balance exceeds their TEP bill for electricity, the credit is applied to their next month’s bill. In October of each year, TEP will pay the customer any remaining RCP credits if the balance is more than 10.

    Customers with grandfathered rates for PV systems installed before 2018 should refer to TEP’s Rider – 4 Net Metering for Certain Partial Requirements Service (NM-PRS).

    Power Outages

    If a power outage occurs, your PV system is required to shut down automatically for safety reasons. This prevents excess energy generated by your system from flowing back to our circuits while our crews are repairing equipment, which must be de-energized to prevent an electrical hazard.

    Your system will not generate energy during a power outage unless you have a PV system with a battery storage system. Once power is restored, you can resume operation of your PV system, which may require a manual reset.

    Maintenance Repairs

    If your system requires maintenance or repairs, contact your solar company. If the existing DG meter needs to be pulled for repairs, a DG clearance from your Authority Having Jurisdiction (AHJ) will most likely be required. If the inverter(s) or modules are being replaced an application will need to be submitted to TEP.

    Working with TEP

    TEP’s role is to assist installers and customers through every step of the application and approval process and ensure that projects meet all safety and electrical requirements. At different stages of the application process, customers and your installers may work with up to four different departments at TEP: Energy Programs, Energy Services (engineering), Design Services and Metering.

    Customers and installers can expect regular communications from TEP to help keep projects on track. Customers can do their part to advance their project and prevent delays by providing TEP with their correct address and email address, signing the Interconnection Agreement in a timely manner and ensuring there are no access issues – such as pets in the yard or locked gates – at their home.

    TEP will review the Notice of Completion submitted by the installer once installation is complete and, if approved, the project will be released to TEP Metering for a meter exchange. Once TEP issues a Permission to Operate, the installer may energize the PV system.

    Steps to Installing a Residential Solar System

    • The solar company completes and submits the Interconnection Application and required documents to TEP on their customer’s behalf.
    • TEP conducts an administrative review of the application and documents within 7 days of receipt to ensure they comply with program requirements.
    • TEP completes an Interconnection Review of the project’s technical specifications within 14 days and notifies the customer and installer if the project is approved or needs corrections. For PV systems greater than 20 kWac, TEP has 21 days to complete its Interconnection Review.
    • The solar company pick-ups TEP-supplied equipment and materials for the project from our designated vendor.
    • The solar company installs the equipment and then notifies TEP when the installation is complete by submitting electronically a Notice of Installation Completion (NIC) along with “as-built” photos of the project. TEP may require a system inspection.
    • TEP reviews the NIC and coordinates with our Metering Department to install billing and solar production meters and complete a revenue meter exchange.
    • Upon receiving Permission to Operate from TEP, the solar company may energize the customer’s PV system.

    Your Installer’s Role Responsibilities

    Solar companies are responsible for designing a PV system tailored to the customer’s home and energy needs, and calculating its size, configuration and energy production. The installer should provide a detailed cost estimate, the manufacturer and model numbers for your equipment and a project timeline.

    The installer will complete and submit the Interconnection Application and project drawings to TEP on your behalf, obtain the necessary permits, schedule inspections and secure the required approvals. They’ll also need to contact TEP if there are any major modifications to a project. Installers must adhere to TEP’s Distributed Generation Interconnection Requirements and our Electrical Requirements.

    If a power kills is needed for installation, the installer needs to schedule this with TEP Design Services and notify the customer of that appointment.

    When a PV system is completed, the installer must submit a Notice of Completion with TEP along with “as-built” photos of the PV system. After TEP installs new billing and production meters and issues a Permission to Operate, the installer will complete a walk-through with the customer and energize the system.

    Changes to your PV System after Installation

    Customers who want to expand their system by adding an inverter or more modules need to have their installer submit an application to TEP. They will keep their initial net metering rate for the duration of the 20-year contact if the addition to a grandfathered system does not require utility distribution upgrades.

    Customers with an RCP rate can find more information about expanding their system and retaining their original rate.
