How to Install a Solar Panel

Solar panel installation involves careful design, secure attachment, and appropriate wiring to guarantee the safety of the equipment outside and the occupants within the house. A qualified solar panel installation business can install your solar panels correctly, lowering the possibility of harming your home or endangering your family’s safety.

The construction of scaffolding or supports is the first step in the installation. These structures are attached to the home’s roof or another part of the property with improved solar exposure if required. The scaffolding’s mounts are then used to secure the panels. The cabling from the solar panels is then routed to a solar inverter and, if desired, a solar battery system.

Finally, the panels are turned on and checked to ensure everything operates before the wire is routed from the inverter to the consumer unit inside the house.

Things to Think About Before Going Solar

There are a few things to consider to ensure that investing in the technology is good for you and your house before rushing in and putting a solar energy system on your roof.


The geographic location of your property will significantly influence the size and kind of solar array you need. Typically, more extensive systems with plenty of battery storage will be more advantageous in northern regions. These systems are often more expensive than those found in southern locations, which benefit from more direct sunshine and are less prone to have a string of gloomy, low-production days.

The immediate surroundings of your house, in addition to its latitude, might impact how quickly your system can generate electricity. Neighbouring trees or higher structures might reduce the sunlight that reaches your solar panels. In such cases, careful preparation may be required.

Electrical Demand in Homes

An extensive solar system can provide enough electricity to power your house thoroughly, except in northern or southern areas. Many people, meanwhile, aren’t necessarily interested in being cut off from the power grid.

The power your system needs to produce depends on how much energy you consume daily in your house and how much you want to divert from the grid to your solar array.

Savings vs. Cost

The tax benefits and rebates offered where you reside may significantly impact the overall cost of your solar energy system. However, you’ll probably still spend a lot of money on your system. However, you will pay less for your energy.

When deciding if the investment is worthwhile, weigh the cost of your system against your short- and long-term spending plans and savings, as well as any price cuts you may be eligible for.

Type of Roof and Slope

Ensure the roofing material is in excellent condition before installing your solar energy system on your roof to save money by not having to replace it too soon. Consider your home’s roof type, solar position, slope steepness, and condition. These elements will dictate where and how you can build your system. Give your installation provider the task of identifying the most excellent options for your predicament.

How to Choose a Solar Installation Company and What to Look for

Selecting a solar company might seem complicated, with so many to choose from. Investigating solar installation businesses is complicated by several aspects, so we’ve put together this list to get you started.

Availability in Your Location

While some solar panel installation firms are more localized and may not be able to accommodate sites outside of a specified radius or area, others are more widely available and can provide installation and services in most U.S. states. Researching the company’s service area is an excellent place to start when reducing your options.

Better Business Bureau Accreditation and Rating

A reputable business with a track record of providing excellent products and services needs to keep its BBB certification. Since the solar energy industry is expanding rapidly, it’s conceivable and probable that you may come across younger businesses that do not yet have a solid reputation throughout your search. Although these businesses may have more reasonable costs, engaging with unproven companies won’t assure you about the quality of their products and services.

Options for financing and advertising

Most solar businesses should enable a homeowner to, if they so want, buy all of the components for a solar system entirely. Although there is a sizable upfront fee, users may immediately use the money they save on energy bills for themselves.

Most of the businesses on our list of the top solar panel installers provide customers with the option to finance a solar installation. To assist you in saving money when investing in solar energy, several businesses also offer referral incentives or equipment bundles.

Equipment: Owned vs. Leased

Some firms that install solar panels will sell you the solar gear so you can buy it r and start saving the money you would have spent on electricity cow. By leasing the solar system to households, other businesses make beginning your transition to utilizing green, renewable energy accessible. This enables you to make immediate financial savings and use utility cost reductions to pay for the equipment.

Estimates and Consultations

Most solar installation businesses will provide a free estimate of the materials and labour costs. If unsure of your need, look for a company that puts its clients first by providing free consultations and estimates. Having a professional take you through the many choices and installation procedures might be beneficial.

Reviews and ratings from consumers

It’s crucial to ensure you choose a firm you can trust since solar installation needs a company’s staff to work inside and on your property. Choose businesses with high customer ratings and reviews since they may provide a wealth of information about a company’s operations and those of its staff.

Solar Equipment

Checking out the kind of solar equipment a firm employs will help you decide whether it’s the best match for your needs to install solar panels. Numerous businesses provide a wide range of equipment from various manufacturers. To save money or because business personnel are informed about the optimal combinations of multiple manufacturers’ equipment, some solar firms may mix and match panels, inverters, and other equipment from several manufacturers.

Companies also provide solar panels in various shapes and sizes, some of which are low-profile or made to withstand more severe weather. Certain businesses, such as Tesla, also provide solar roofing tiles.

Solar equipment types

When discussing your choices with a solar firm, you should be aware of a few essential elements that are part of any solar arrangement. It will be easier for you to choose what is ideal for you if you have a basic grasp of the various components of a solar system.

solar cells

Solar panels take in the sun’s energy and transform it into an electric current. When creating your solar system, you may pick from a variety of solar panel types, including:

The most popular kind of solar panel used in residential installations is monocrystalline. Although they are the most effective and long-lasting panel form, they are also expensive.

Despite having a lesser efficiency than monocrystalline panels, polycrystalline panels are preferred by specific customers because they are more affordable.

Thin-film panels are more flexible, lighter, less expensive, less efficient, and more durable than the other types. R.V.s, camping batteries, and different transportable installations employ thin-film panels more commonly than residential installations.

Hardware and Cables

Solar panels must be firmly fastened to whatever surface you install them on (often your home’s roof). Hardware describes the mounting apparatus and support framework to which the solar panels are fastened. The cables link the panels to the rest of the setup so that the electrical current generated by the panels may be utilized in your house. They also connect the panels to the other electrical parts of the system.

Energy Converter

Direct power generated by the solar panels must be converted into alternating current for use in your house, which requires an inverter. The inverter controls this crucial transition since the two current types cannot coexist.

batterie solar

You may store extra energy from a solar system for later use using solar batteries, an optional feature. When the energy produced by the panels is insufficient to power your house, such as overnight, during grid disruptions, or on extremely overcast days, you may use the stored energy. Solar batteries are still necessary upgrades for entirely off-grid dwellings. The majority of home systems use lithium-ion or lead-acid solar batteries.

Charge Controller

A charge controller can route energy to where it is most required if your solar panels produce more power throughout the day than your house uses. For instance, if additional energy is generated, the controller will transmit it to the local power grid or any solar batteries that are still empty.

Solar Shingles and Roofing

Solar roof shingles and roofing are a more recent addition to the sustainable energy scene than large solar panels. Without drastically altering the appearance of your house, they can provide all the electricity you want. Many businesses now offer solar roofing that completely replaces or sits on top of your roof shingles. Although they are currently more expensive than conventional panels, their price decreases as technology develops.

Solar State Incentives and Solar Tax Credits

Numerous federal and state incentive schemes exist to lessen the high initial cost of a new solar installation. You might save several thousand dollars if you’re eligible for state-based incentives in the Database of State Incentives for Renewables & Efficiency. Furthermore, the Federal Solar Tax Credit (2023) provides a 26% discount on the cost of a new solar system.

A practice known as net metering, which may help you save even more money on your monthly electric bill and benefit the environment and community, is one that many utility providers will provide homes with in addition to incentives and rebates.

Warranties of the Solar Company

Some common elements exist among businesses’ many warranties on their goods and services. Most solar panel suppliers provide 25-year guarantees for panel performance and manufacturing flaws. Other components’ warranties might vary significantly depending on the kind of component and the manufacturer, such as batteries and charge controllers.

Because installing hardware and wiring often requires modifying existing house structures, several businesses additionally provide coverage against property damage during installation. Although nearly typically included as standard, coverage periods might vary.

Usually, businesses that provide solar system leasing will take care of any problems during the contract term. Usually, the leasing business will also be in charge of any necessary system maintenance.

Different Solar Warranty Types

Manufacturer’s Equipment guarantee (Product Guarantee): A manufacturer’s equipment guarantee, also known as a product warranty, offers typically premium, high-quality solar panels 25 years of protection and covers manufacturing flaws and panel failure.

Performance Warranty (Power Guarantee): A power guarantee is an assurance from the manufacturer that the output of your solar panels will remain at a certain level compared to when they were first installed. The typical duration of performance guarantees is between 10 and 25 years, with percentages of around 90% after ten years and 80% after 25 years.

Workmanship Warranty: Any damage to your solar energy system that occurs during or as a consequence of installation is covered by an artistry or installation warranty. The length of coverage might vary from two to fifteen years or more.

The efficiency of Solar Panels

The ratio of sunlight reflected to sunlight absorbed determines the effectiveness of solar panels. Solar technology has undoubtedly advanced in recent years; solar panels currently have an average efficiency of 18% to 20%, up from a 15% average in the past.

Different panel types provide varying degrees of efficiency. The quantity of solar exposure, the weather and temperature, the panel’s colour, and the panel’s cleanliness may all impact efficiency. The overall effectiveness of a solar system is also influenced by its other elements.

The power output of each solar panel is compared to a theoretically ideal efficiency rate of 1 kW of sunlight over one square meter to get the efficiency rating of solar panels.

Solar energy is measured in kW or kilowatts. A typical house of 2,000 square feet will consume around 32 kW per day.

What Are the Prices of Solar Panels?

The demands of your family, the size of your setup, the kind of panels you choose, the business you select/installation charges, any accessories you add to your system, and your location may significantly impact the price of solar panels.

A domestic solar installation may cost between $5,000 and $40,000. However, this cost can be reduced by the state incentives, solar tax credits stated above, and long-term power savings.

Do Solar Panels Pay Off?

Yes, solar panels are often a wise financial and moral investment. Although buying and installing a solar system may be expensive up front, you will save a lot of money on your electricity bill and help the environment. In most cases, the benefits of adopting solar much exceed the drawbacks.

Although the size, extra components, and total cost of a solar array might vary depending on the location of your property and the amount of sunshine it gets, the reduction in your energy costs and the instant advantage of raising the value of your home is constant.

However, suppose your location requires you to spend more on a system that can only create a certain amount of electricity. In that case, it will probably take longer before you see a return on your investment that makes it worthwhile.

How Much Does The Average Homeowner Save With Solar Energy?

A 30-year solar array lifetime results in an average solar energy savings of between $25,500 and $33,000, or around $1,500 per year. Your system’s total cost, the quantity of energy it can generate and store, and the size of your present and projected energy bills will all affect the savings you see.

Motives for Working with a Solar Panel Installation Company

Although locating the necessary tools and DIY a solar panel installation is feasible, most people are unlikely to find it beneficial. Hiring a certified and insured business to install your solar system should give you peace of mind that the work will be completed expertly by trained personnel. You’ll know who to blame if anything goes wrong after installation, and a reputable business should provide a warranty against artistry faults.

Hiring a qualified, experienced installer will probably be worth the extra money upfront since saving a cent by doing energy installations on your own might easily cost you a dollar in the long run.


How much does installing solar panels cost?

Depending on the style, model, and other factors, most home installs range in price from $5,000 to $35,000, with a fully equipped system costing, on average, $16,000. This excludes any tax rebates or other incentives, as well as the cost savings from forgoing utility payments for electricity.

What are the environmental benefits of solar energy?

The usage of solar energy may take the place of burning fossil fuels. When burnt, fossil fuels—a non-renewable resource—release greenhouse gases into the atmosphere. Solar energy is sustainable and renewable despite any “startup” expenses for materials and production.

To power a home, how many solar panels are required?

The typical American family will need around 20 to 25 panels to meet electrical demands. This estimate will change depending on your household’s energy use patterns, solar exposure, geography, and panel efficiency.

A home audit and energy assessment may establish how much electricity your system must produce and how much storage space is required to run your house continuously for an exact count. The number of solar panels your property needs and any necessary energy storage options will be determined after the consultation.

How often must one clean solar panels?

For maximum effectiveness, panels should typically be cleaned every six to twelve months. A buildup of dirt or debris will hamper your system’s performance.

How durable are solar panels?

The typical lifetime of a solar panel is 25 to 30 years before it starts to lose significant efficiency. The performance guarantee offered by reputable solar panel producers indicates typically that after ten years of usage, the panels will generate at least 90% of their initial output and roughly 80% after 25 years.

How do solar cells function?

Photovoltaic (P.V.) cells, used in solar panels to capture solar photons, comprise semiconductor materials like silicon. The photons cause the semiconductor material to release electrons when the screen absorbs them. We may direct the electric current produced by the movement of these electrons inside the cell to our circuits.

Are there any reliable local solar installers?

Based on geography, local solar installers will probably understand your solar demands more in-depth. A local installation could also charge less since they have more minor overhead expenses. Because of these factors, local solar installers often outperform large national solar enterprises.

However, when choosing who to hire, ensure the local installation is a respectable business that complies with all local licensing and insurance regulations. To be sure the facility you choose is the most excellent match for your home’s requirements, compare the costs and ratings of local, regional, and national businesses.

What is net metering?

You may lower your monthly power cost by selling any additional energy you don’t use back to the grid under a net metering scheme. Your savings may vary greatly depending on where you live and which power provider services your region since some utility companies will give you credit for the retail price of the energy. In contrast, others will offer you a reduced wholesale price.

Does power come from solar panels at night?

Solar panels won’t produce power when they aren’t directly exposed to the sun. Solar batteries may store excess energy generated throughout the day, which can then be utilized to power your house while your panels aren’t producing electricity.

What drawbacks does solar energy have?

Even environmentally friendly energy sources have both positive and harmful aspects. There are benefits and drawbacks to solar energy. High up-front expenses, a commitment over time, issues with recycling and manufacturing that affect the environment, the requirement for space, and reliance on consistent sunshine are some drawbacks of solar energy.
