    things you must know about solar panel’s location orientation now!

    Many people around the world are now switching to solar energy. This is because it is an efficient way to produce energy that is sustainable and eco-friendly. But, there are some things you need to know before you get your solar energy system setup. They are:

    Solar Panel Location:

    In the case of solar energy, constant contact with sunlight is essential for the best outcome. To ensure the solar panel has all-day access to sunlight, the best place is the rooftop. The solar panel’s roof direction helps it soak up as much sunlight as possible throughout the day. Even in bad weather conditions like heavy rain, it is helpful. As the rain falls, the water will help clean the entire surface of the panel without zero to no effort. This is why you can see the solar panels for homes are generally installed on the top of the house.

    Solar Panel Orientations:

    As we already know, to get the maximum amount of energy out of solar panels, it is important to find the optimal solar panel orientation. After tedious research, scientists have found that facing the panels south in the northern hemisphere has the highest efficiency. When it comes to the southern hemisphere, it was found that the best direction for solar panels is north.

    Solar Panel Angle:

    When it comes to solar panels, there are two must-know solar angles, which are azimuth and zenith. Solar Azimuth is the angle of the Sun’s direction. This is measured based on the sun’s clockwise travel from the horizon to the north. The solar zenith is the angle formed by the local zenith and the sun’s line of sight. By putting both these angles together, the solar panel installation is done.

    Solar Panel Tilt:

    When it comes to any PV panel, including west-facing solar panels, their angle while facing the sun is crucial. Based on research, many experts have recommended that solar panels in California should have a tilt of 19 degrees. This angle was discovered to produce the best results throughout the year.

    As the solar energy industry is expanding, it is very important to know more about this technology. You can also visit SouthWest Sun Solar to learn more about solar panels and their installation!

    Southwest facing solar panels

    • SOLAR

    The sun’s rays should hit a solar panel perpendicularly to achieve the greatest efficiency. If you live in the Northern Hemisphere, the best direction for solar panels is generally south, based on lines of longitude. But there can be differences depending on where your home is located, how your roof is oriented, and other factors.

    For homes in the same climate, a solar panel system installed on a southwest/southeast facing roof will produce about 8% less power than one on a south-facing one. If the panels are mounted to face east or west, on a standard pitch roof, they’ll achieve 15% less output, while north facing panels will produce about 30% less power than those oriented southward.

    The exact impact varies depending on your latitude, number of degrees the panel points away from true south, and roof pitch.

    Best Direction for Solar Panels FAQ’s

    Q: Is Due South Always the Best Direction?

    A: The angle of the sun changes throughout the day, and with the seasons. Even a south-facing panel won’t get direct sunlight all day. But you can choose the best angle for your location and latitude. For example, if you live near 32 degrees latitude in a location such as Dallas, Texas or Charleston, SC, your panels should be tilted at a 32-degree angle to maximize solar production.

    That’s unless you install a solar panel tracking system. This allows the panels to rotate and follow the sun throughout the day. Suited for ground-mounted solar panels, tracking systems come in different configurations. A single-axis system can only move in one direction, but a dual-axis one can move along a north-south and east-west axis for more precise positioning.

    Q: Other Perks of South-Facing Solar Panels

    A: If your home has access to net metering, facing your solar panels south increases output and sends more power to the grid. During mid-day hours, energy collection is higher. Since most people aren’t home then, more power is generated than needed, so you can get reimbursed for more. Time of use (TOU) rates are also a consideration. With TOU rates, power sent to the grid during peak hours is worth more, so pointing solar panels to the west or southwest later in the day can help earn you more money.

    Q: What If My Roof Doesn’t Face South?

    A: You can still save, even without having the best direction for installing solar panels. One way to get around the inefficiencies is to install more panels, which likely won’t impact the overall cost of installation. That’s because the panels themselves are only a small proportion of the cost of procuring and setting up a photovoltaic system. And the extra panels can add enough power output to benefit as much as having south-oriented solar panels.

    But if you have the yard space, you can install solar panels on the ground. While it’s less costly than fitting large racks on your roof, you’ll need to brush leaves, dirt, and perhaps snow off the panels. This isn’t hard as you don’t need to climb a ladder to do it. However, the amount of yard space needed for installation can be substantial.

    How much less efficient are north-facing solar modules?

    By Paul Grana, co-founder, Folsom Labs

    It’s considered common knowledge that you want to point your solar modules south, toward the equator (assuming you are in the northern hemisphere). This maximizes the energy production over the course of the year, through both summer and winter.

    Sometimes, however, the homeowner will want to add modules on the north-facing roof. This may be for aesthetic purposes, or sometimes because the south-facing rooftop isn’t fit for solar. The most common rule-of-thumb is that you simply can’t do that. But we wanted to ask, how bad is it to put solar panels on a north-facing roof?

    How much worse are north-facing solar modules?

    We start with a typical residential system in Charlotte, North Carolina. We designed and modeled the system in HelioScope, our sales and design software platform. With a 2/12 pitched roof (9.5° tilt), the south-facing array will produce 1,361 kWh/kWp [1]. A north-facing array on that same building will produce 1,145 kWh/kWp—a difference of 16% compared to the south-facing array. Not great, to be sure, but probably not as bad as you might expect!

    things, know, solar, panel, location

    The tilt of the roof matters a great deal. If this same system was on a shallow 1/12-pitched roof (with a tilt of 4.8°), then the south-facing array would produce 1,315 kWh/kWp, while the north-facing array would produce 1,205—a difference of just 8%! If the roof were steeper (say, 4/12), then the north-facing array would be 29% worse.

    The orientation of the house also matters. The above examples are for a house facing perfectly north-south. But if the house is facing south-southwest (30° off of perfectly south), then the equator-facing roof is only 14% better. And if the roof is 60° off south, then the equator-facing roof is only 8% better.

    things, know, solar, panel, location

    We can summarize all of the various roof tilts and orientations for Charlotte in the table below:

    Finally, the location also matters, as north-facing modules do better as the array gets closer to the equator. For example, if we were in Florida compared to North Carolina, the north-facing array would be just 12% worse than the south-facing array (versus 16% in North Carolina). On the other hand, that same array in Massachusetts would be 20% worse.

    things, know, solar, panel, location

    As a rough rule-of-thumb, north-facing modules that are within 10% of the south-facing modules are still extremely likely to be profitable if they can be used to expand the system size (while modules that are within 20% of the south-facing modules are often worth adding). This is because the north-facing modules would incur only the marginal costs (hardware, installation labor) not the fixed costs. After all, you’ve already paid the costs to acquire the customer, to obtain the permits and to send the crew to the site. If the performance gap is smaller than the percentage of fixed costs for the system, then the modules can be profitably added—and in the SAM cost structure, the fixed costs are 32% of residential system costs, implying that the hurdle for profitable inclusion of modules is actually 32%. As a result, we can color-code the various tilt-azimuth combinations for the Charlotte example. The north-facing section of 1/12 roofs are likely to be extremely profitable, while 2/12 rooftops (and select 4/12 rooftops if they are not perfectly facing south) would be worth consideration for the system design. Here are a few examples for Charlotte, Miami and Minneapolis:

    Why isn’t energy production as bad as expected?

    Most people will be genuinely surprised by these results, with good reason. Pointing modules “away from the sun” is, for many people, something you simply don’t do. But there are a couple reasons for the decent performance of north-facing modules:

    Diffuse sunlight will be the same for both the south- and north-facing arrays. There are basically two components of sunlight: the direct beam from the sun (called “direct”), and the glow of the blue sky (called “diffuse”). So while equator-facing modules do better with the direct light from the sun, they both receive similar amounts of diffuse light, which typically accounts for about 30% of the array’s energy.

    Direct sunlight is based on a cosine function. The amount of direct sunlight a module receives is based on the cosine of the angle—which, as seen below, is actually somewhat flat, especially near the peak. In other words, the difference between pointing right at the sun, versus being slightly off, is smaller than in other situations.

    The sun is overhead in the summer, when the array is most productive—so the arrays are nearly identical during the most crucial times. As can be seen in the chart below, for our original reference project in Charlotte, the north-facing array is nearly identical to the south-facing array in the summer months, when production is greatest. While the differences are much larger in the winter months (over 20%), the energy yield during those times is much smaller.

    What about higher-tilted rooftops?

    The analysis above shouldn’t imply that roof tilts max out at 4/12, or that north-facing modules always make sense. Moderate roof pitches (from 4/12 up to 9/12) can be common, especially in northern latitudes where the steeper tilt helps the roof to shed snow before the weight builds up. So let’s see how much worse the numbers are for steeper roofs in Minnesota:

    In Minneapolis, a 10/12 pitched roof that is perfectly north-south will have a 57% penalty between the south-facing and north-facing modules. In fact, it is pretty unforgiving, even if the house has a southwest angle. And for those in the northeast, Minneapolis is at a latitude of about 45° North, which is in line with Bar Harbor Maine.

    On the other hand, steep roofs in Charlotte are less painful, but still not great. A 7/12 pitch could potentially make sense if the roof is oriented to the southwest:

    But these modules are clearly borderline (20-30% less productive than the south-facing roof). Clearly, as with any design rule, the right approach will often depend on the location and application.

    The rise of north-south rooftops

    “Dual-tilt” racking is already popular in commercial flat-roof designs (with products from companies like SunPower, SolarCity/Zep, Everest and Renusol). This new residential design approach would extend those principles to residential systems as well. In an era of cheap modules, ideas that previously seemed crazy can suddenly become completely sound.

    [1] This is a measure of the productivity of an array, providing the number of output-hours the system produces energy. For example, a 5-kW system that produces 1,700 kWh/kWp will generate 8,500 kWh per year (5 x 1,700).

    In California, this information matters greatly for homes in an HOA association, which accounts for a large percentage of new homes in metropolis areas. Essentially, California law dictates that associations can’t tell you to locate (all of) the panels on a roof that’s over a 10% loss from your preferred location. Our association does exactly that; forcing people to use their rear roof. Only this law allows those homeowners to have a viable installation. So; get that all you California haters! The State actually intervene on behalf of letting people do their thing!

    How would all this be for amorphous (CIS/CIGS) solar panels which tend to be less sensitive for different angles of attack of the light. How would they perform on the north side compared to the south side? Is it maybe wise to use mono-crystalline panels on the south facing side and amorphous panels on the north facing side?

    So on a typical ranch house roof in Southern California, sounds like there would be about a 25% reduction. If I’m using 400w panels, they would effectively be 300w panels. So I can simply think of this as adding 300w panels. Still very well worth the ability to increase the number of modules.

    Nova scotia, home sits 60degrees north east. Feburary as it is now, my north side of the roof is in sunlight until 430. Southern side sun all day. Is this a roof that can take panels on both sides of the home? My northern side gets sun first from the east.

    Would the % differences indicated apply year round through the seasons? The reason I ask is that when the sun is really low in my latitude of 42 degrees, the north side of my roof does not have any solar contact.

    Extremely useful. 5% pitched roof here in france, so well worth panelling. Couldn’t find this information anywhere else. So thanks!

    Minneapolis resident here with a northern facing pitch of between 2/12 and 4/12. Our north face actually accumulates snow which creates a hassle with ice dams. But I’m curious to know have other MSP homeowners taken the plunge anyway, and have they seen serious maintenance issues with north facing panels. Also curious to know about the dual tilt setup. Does that mean a panel that’s angled off the roof, toward the south?

    For the diagrams, is it for the roof orientation or the house orientation? The article says house orientation, but the roof orientation can be any direction depending upon how it is built. I would think roof orientation is more important than which way the house faces. Thanks.

    I am certain late to add to this conversation but what about the effect from snow? Obvious that a north facing slope is going to have a shit load of snow on it that’s going to hang around for a while. And you were most definitely going to get reflection off any kind of build up over the panels.

    I think that another component to this study would be to project how North facing panels affect the customers’ return on investment (ROI). After all, selling more panels and being more profitable should not be placed ahead of the customers’ goal of the system paying for itself as quickly as possible. Additionally, double-faced (panels that use thin-film along with crystaline) should be considered. I would also like to see if at any point during the year the north facing panels will not provide enough power to even turn on their inverter.

    Barrett Silver, I thought, the writer already mentioned that at 7/12 (30.3 degree) steep roof in Minneapolis; the north facing side would be about 48% less efficient versus south facing side. let me know if I am wrong. Thanks.

    The average roof pitch in the US is a 5/12 the only time your 30% loss applies is during the summer. what about during the rest of the year? When PV panels are 68/watt we can waste and feel good about it. Salesmen who have never had to rely on PV production to live will go around with these charts to sell there wares. This is going in the wrong direction for energy conservation and the bright future on renewables.

    This is a great analysis but it would be much more useful to include a range of roof pitches that goes from 1/12 to 12/12. A 1/12 roof is effectively flat, or nearly so. Looking at 4/12 as the steepest pitch in your analysis ignores the fact that architectural styles in many regions consistently favor roof pitches between 5/12 and 10/12.

    I’m not familiar with this method, but roof slopes. My roof has a 24º pitch. Unfortunately one of 2 sets of panels are on the North facing side. Fall/Winter months suck for solar generation being 24º away from the sun.

    Your examples are treated accurately, but I find them misleading, especially for those of us in the Northeast. Steeper roofs are also more common here because of the snow loads. An ideal south facing roof here is pitched at 7/12 (39ish degrees) and the north side of that roof will produce less than half as much electricity. Adding modules on the north side of the roof will not add much bang for the customer’s solar buck and would qualify as solar malpractice in my book.

    Southwest facing solar panels

    Over the past decade, the cost of a solar electric system (solar PV) has dropped significantly. With the advent Made-in-WA solar components and a production incentive rate paid to WA property-owners who install grid-tied solar, the numbers of homes with new solar systems in our state has skyrocketed.

    You too can get clean renewable solar electricity to meet a portion of your annual energy needs.

    How Much Electricity Do You Use?

    When determining what solar PV can do for you, the first question is how much electricity do you need? That is, how many kilowatt hours per year of electricity do you currently use? Before you call a solar installer for a bid, gather up your electric bills and figure out your usage. Then the solar system can be tailored to both your site and your usage.

    Evaluating Your Home for Solar

    Sunlight is the fuel for all solar technologies, and the term solar resource refers to identifying how much of it is available in a given collector area. Three significant factors affect the power output that you can expect from a roof or ground mount solar installation: direction the roof is facing, shading, and roof pitch.

    • Direction: South-facing is ideal. Southeast and southwest facing roofs will still receive a lot sun. East and west facing will receive less, but may still receive enough sun. Roofs that face north facing will not receive enough of solar resource to make sense.
    • Shading: Solar panels should have direct access to the sun, with little to no shading, for 6 hours of direct sun per day year-round. Common things that may reduce sunlight are shade from buildings, trees, hills or roof features like large chimneys.
    • Pitch: The ideal roof is between 20 and 35 degrees, though steeper and flatter roofs may still work.
    • Sufficient space is also a factor. When designing solar for a particular roof, the panels must be arranged not to cover up vents, skylights, chimneys, etc. Often the limiting factor on system size is the available roof space.
    • You can learn about your site’s possible power output from the PV Watts website or from Google Project Sunroof online tool.

    Site Assessment

    For an accurate cost estimate of solar for your home, a solar installer should visit your home to measure solar exposure and roof space, evaluate your electric breaker panel, evaluate your site, make a plan for panel locations, wire runs, inverters, production meter, and any other components. They will discuss with you any site specific concerns or factors that affect cost.

    • The solar installer will design options for you taking into consideration things like fire code requirements for distance from the peak of the roof.
    • After the site assessment, the solar installer should provide a proposal with system options, estimated power output for each option, diagram or text explaining the rooftop plan, and terms of the contract.
    • The solar proposal should estimate for you the annual and long term savings on your electrical bill, as well as payments to you from incentive programs and tax benefits so you can see the long term benefits, the upfront costs, and payback time period. The following incentives apply if the home owner qualifies:
    • 30% federal income tax credit.
    • State of Washington Incentive – paid at a per KWH rate for the solar electricity your system produces before any gets used. Annual maximum of 5000. Highest payment rate for Made in Washington solar panels. Payments are made once a year for 8 years or until you’ve earned back 50% of the cost of the system (including sales tax), whichever occurs first. A solar system is classified as “residential” when it is sized 1 to 12 kW; larger than 12 kW is classified as “commercial” size.
    • Net Metering – electric bill savings.
    • Possible additional incentives your utility may offer.

    Homeowners Associations

    If your residence is governed by a Homeowners Associations (HOA’s), visit this page of resources about Solar HOA’s. Learn more about the Solar Incentives for Washington homeowners. Here is a link to RCW 64.38.055 from the Washington State Legislature to governing documents concerning solar panels. Check out a presentation on this topic from March 2015 concerning HOAs and solar.

    On March 4, 2021 Solar Washington welcomed back Kathleen Kapla, principal of Kapla Law PLLC, who addressed laws, guidance, and model resolutions for HOAs in Washington as they pertain to solar PV. Kathleen returned from her March 2015 presentation for Solar Washington to provide a refresher and any updates that have occurred in this area since then.

    Price Financing Your Purchase Installation

    Residential size solar systems are systems of capacity up to and including 12 KW. System range from around 15,000 to 30,000 depending on system size, specific components, complexity of installation and other factors. So, it is about the same as buying a new car.

    These financial institutions, based in Washington, specialize in solar-specific loans for home-owners:

    Another option is to utilize a Home Equity Line of Credit on your existing home loan.

    The Clean Energy States Alliance in partnership with the federal Office of Energy Efficiency Renewable Energy published a free guide to help homeowners navigate the complex landscape of residential solar PV system financing. Download the complete Homeowners Guide to Solar Financing (PDF).

    Hiring a Contractor

    Do your homework. Call more than one installer and get several bids before choosing a company to install solar on your property. Review our list of Consumer Questions! Ask the companies if they abide by the SEIA Code of Ethics.

    Setback from Roof Peak and Sides

    International Fire Code dictates how much of the roof can be covered with solar panels and how close the panels can go to the ridgeline. Your solar installation company should know and understand these rules.


    • Once you and your chosen installer agree on the system details, either you or your installer must apply for the necessary building permits per city ordinance (maybe none), electrical permit, and utility interconnection application. Your installer will create a line diagram which is part of the application.
    • Once your utility approves your interconnection, an installation typically lasts one to three days for residential rooftop; longer for ground mount.
    • When installation is complete, an electrical inspection is required.
    • Within five to thirty days, your utility will install a new production and net meter and then your solar system begins producing power that saves you money on your bill.
    • You must register your solar system with WSU Energy Office and pay a one-time fee of 125 in order to receive your annual WA production check. Click this link to register.


    • You probably want to add your solar system to your home-owners insurance policy.
    • Use your paid invoice to document your purchase to get your federal tax credit.
    • Apply annually to receive your state Incentive payment.
    • Check the system at least monthly to make sure it is working.
    • Clean the solar panels at least annually or more often if you notice dust and pollen accumulating. Follow manufacture’s guidelines.

    Solar panels provide an easy way to get energy savings and reduce your carbon footprint when providing electricity to your home. Before you opt to have solar panels installed, it’s vital that the panels are facing the correct direction and that they are placed in the right location in order to harvest the sun’s energy effectively. Make sure that you hire an experienced solar panel installer who is familiar with your area and your particular climate to ensure the best results.

    Solar panels should be installed facing south when installed on your roof. The sun reaches its peak in the afternoon, so the solar panels should get the best exposure when they are facing south rather than north, east, or west in order to optimize energy production during the day.

    Aside from facing the right direction, solar panels should be completely free of any obstructions. These obstructions can include things like tall shade trees, tall buildings or other homes nearby, or roofs with extremely steep angles. Make sure that your roof has plenty of space to mount the panels while ensuring that they’ll be able to get maximum sun exposure for many hours each day.

    Can Solar Panels be Installed on North Facing Roof?

    The orientation of your solar panel will affect just how much energy it can produce, so choosing the right direction is vital to ensuring that they operate as efficiently as possible. If you want to install solar panels on a north-facing roof, it really depends on several factors, including your location and your climate. Remember, solar panels receive the most and best direct sunlight when they are installed on a south-facing roof.

    You will need to mount your solar panels in the opposite direction of the roof’s slant if you want them installed on the north-facing side. Alternatively, consider using the ground-mount method of installation if you can’t install the panels on the south-facing side for the best results.

    Energy production is very limited when solar panels are installed on the north-facing side of the roof, so it’s not recommended unless it’s absolutely necessary. Try ground or pole mounts instead, so that your solar panels are somewhere on the south-facing side of the home. Just make sure that the panels are not obstructed by things like trees, patio canopies, or other things that could block the panel and keep it from absorbing the most amount of energy possible.

    Can Solar Panels be Installed on North East Facing Roof?

    Homes located in the northern hemisphere (including the United States) should have solar panels installed on the south-facing side of the roof whenever possible. If you install the panels in any other direction, they likely won’t be able to harness the proper amount of energy required to power your home the way they should. You might wonder if it’s OK to install solar panels on a northeast-facing roof, and the answer really depends on a few key factors.

    If your solar power is paired with a viable home battery backup system, it may be fine to install it on a northeast-facing roof. However, choosing a pole or ground-mount solar panel installation is a better choice since the panels will get more sun exposure on the south-facing side of the home.

    The north and northeast side of your home is the least viable option for solar panels. Always consider using an alternative mounting method if you don’t have room on your roof to install the panels on the south-facing side. Expect your panels to produce at least 30 percent or less energy if you have them installed on a northeast-facing roof.

    Can Solar Panels be Installed on West Facing Roof?

    The sun is always in the southern sky in the northern hemisphere, so the south-facing direction is ideal for solar panels. Anything facing west will typically produce anywhere from 15 to 20 percent less energy than south-facing panels will.

    Consider factors like your local climate, your utility company’s rate structure, and any incentives for solar panels that will help you make the best return on your investment before deciding where to install them.

    If solar panels are installed on a west-facing roof, they’ll produce less energy than when they face the south. Make sure you know when your peak hours are for electricity use, then determine what time of the day the panels will get the most sunlight if they’re on the west-facing side.

    When it comes to energy savings, you may do just fine with solar panels installed on a west-facing roof. Look at the type of pricing structure your utility company uses since if they use a time-of-use structure, you could pay more for usage during peak demand. In this case, a west-facing installation may work out just fine to help you save money on your monthly energy bills

    Can Solar Panels be Installed on East Facing Roof?

    Ideally, solar panels should be installed on a south-facing roof, but that isn’t always possible depending on your roof pitch, size, and other factors. If you want to install solar panels on an east-facing roof, you’ll still get much of the same energy-saving benefits that you would when they’re installed on a south-facing roof. It often comes down to how your local power company bills your electricity use each month, your specific climate, and the roof pitch,

    You can install solar panels on an east-facing roof, but you’ll likely receive about 80% as much electricity as you would if they were south-facing. Make sure that you choose an experienced solar panel installer who will add them at the appropriate angle and height.

    You’ll still see significant savings on your monthly energy costs if you choose to install solar panels on an east-facing roof. The exact amount of power they generate depends on your position, your roof slope, and other key factors. It’s best to use a solar calculator to determine just how much the electricity output compares against solar panels installed on south, north, or west-facing roof versus those facing east.

    Can Solar Panels be Installed on South Facing Roof?

    The sun’s path moves in a southern direction for those living in the northern hemisphere. Installing solar panels on a south-facing roof is always your best option if you want to garner the best results and the most electricity output possible. But this doesn’t mean that you can’t install the panels facing another direction in order to get the benefits that solar power provides.

    Yes, solar panels can (and should) be installed on a south-facing roof whenever possible. This will ensure that the panels are receiving the most amount of direct sunlight for the longest amount of time during the year and the day for maximum functionality.

    Can Solar Panels be Installed on South West Facing Roof?

    While the general consensus is that solar panels should be installed on a south-facing roof, some experts claim that southwest or west-facing might be even better. Most people use electricity during the peak hours of the afternoon and early evening, and that’s when the sun begins to move from the south to the southwest and west. You could consider this option if you live in areas of the country like California, where many solar companies are pushing to change the direction to west or southwest.

    This article is owned by and was first published on October 19, 2022

    Yes, solar panels can be installed on a southwest-facing roof, especially if you use a lot of energy during the afternoon and early evening. Look at your home’s energy consumption and take note of the peak hours to determine if this is the right option for your home.

    Can Solar Panels be Installed on South East Facing Roof?

    Sometimes, you may not have a choice as to where your solar panels will be installed. In this case, choosing a different part of your roof may be the only option you have. Solar panels installed on a southeast-facing roof can still provide you with plenty of energy-saving benefits.

    Yes, you can have solar panels installed on a southeast-facing roof, but it’s important to note that you will likely get approximately 8 percent less energy output when the panels are installed facing this direction.

    For solar panels, the term true south is defined as the geographic south, which is the direction that is facing the South Pole and is usually approximately 171 degrees on a compass.

    What Direction Should a Solar Panel Face for Optimal Output?

    Ideally, solar panels should face true south in order to get the highest level of energy output. A professional solar panel installation company can look at your home’s location, the roof pitch, and other factors to determine exactly where your new panels should go.
