5 Solar Panel Tilt Calculation Methods
Here are 5 different ways to calculate the optimal solar tilt angle for your location:
- Our Solar Panel Tilt Angle Calculator
- Simple Rules of Thumb
- An Excel or Google Sheets Spreadsheet
- The PVWatts Calculator
- A Stanford Research Team's Tilt Angle Formulas
Let's run through each way, step-by-step.
1. Our Solar Panel Tilt Angle Calculator
Scroll up to our solar panel angle calculator at the top of this page .
In the box, enter a location such as your address, city, or zip code. I live in Atlanta, GA, so I typed "Atlanta" into the box.
Then select your location from the dropdown results. I selected the top result: "Atlanta, GA, USA".
The calculator will calculate the optimal year-round solar tilt angle (from horizontal) for your location. Mine is 28.6°.
Scroll down and you'll see it also calculates your best tilt angles by season and month. Here are mine:
Alternatively, you can just click "Use Your Current Location".
Then click "Allow" when the site asks to use your location.
The calculator will then use your current location to calculate your optimal solar tilt angle.
2. Simple Rules of Thumb
Don't wanna mess with any solar tilt calculations?
Here are 2 simple rules of thumb for finding the best solar panel angle for your location:
Rule of Thumb: Set your solar panel tilt angle equal to your latitude.
Seasonal Adjustments: Subtract 15° in the summer. Add 15° in the winter.
And if you wanted to adjust your solar panels every month, you could just adjust them by 5 degrees each month -- bottoming out in June and maxing out in December in accordance with the summer and winter solstices for the northern hemisphere (or vice versa if you live in the southern hemisphere).
To find my latitude, I went to Google Maps. Then I clicked on the map near my location. (For this example I just clicked in the center of Atlanta.)
Once I did, I saw my location's latitude and longitude coordinates at the bottom of the map. The first number is my latitude.
According to Google Maps, my latitude is 33.7°.
Thus, using these rules of thumb:
My optimal year-round tilt angle: 33.7°
My optimal tilt angles by season:
- Spring: 33.7°
- Summer: 18.7°
- Fall: 33.7°
- Winter: 48.7°
For comparison, when I plug my location into our calculator at the top of this page, I get an ideal year-round tilt angle of 28.6°.
3. An Excel or Google Sheets Spreadsheet
Here's a free spreadsheet for calculating the ideal angle for your solar panels:
How to save your own copy of the spreadsheet
1. Click "Copy the Spreadsheet" above.
2. Click "Make a copy" on the next screen to save a copy of the spreadsheet to your Google Drive. (If you aren't logged in to Google, you will first be asked to log in.)
3. If using Excel, go to File > Download > Microsoft Excel (.xlsx) to download the spreadsheet as an Excel file. Then open it in Excel.
Now that you have your own copy, here's how to use it.
How to use the spreadsheet
1. Enter your latitude . In this example, I just entered mine, 33.7°.
2. Locate your optimal year-round tilt angle . The spreadsheet includes a formula that will automatically calculate the angle based on your latitude.
3. Scroll down to locate your optimal tilt angles by season and by month . These are seasonal and monthly adjustments based on the simple rules of thumb mentioned above.
Note: You do not need to send me a request for editing permission to use this spreadsheet. Just make a copy of it following the instructions above.
4. The PVWatts Calculator
The PVWatts Calculator is a solar energy calculator made by the National Renewable Energy Laboratory (NREL).
I think of it as the gold standard for estimating how much solar energy your system will produce.
How to use PVWatts to find your optimal solar tilt angle
1. Enter your address then click "Go". For this example I've entered the address of Atlanta City Hall.
2. On the Solar Resource Data page, scroll down to the map to confirm that the calculator found the right location. If it did, click "Go to system info". (If it didn't, click "Change Location" and try again.)
3. On the System Info page, experiment with different values in the "Tilt (deg)" field until you find the tilt angle that generates the most electricity. Start by typing in a number, then click "Go to PVWatts results". I entered "29" as my first tilt value.
Tip: Use our solar panel tilt angle calculator at the top of the page to get an angle to use as your starting point in PVWatts. I did this and got 28.6° which I rounded up to 29°.
4. Note the estimated system output. At 29° tilt, this solar power system at my location would generate an estimated 5,809 kWh per year.
5. Go back to the System Info page and edit the tilt number up and down in increments of 1 until you find the tilt angle that generates the most solar energy at your location. After trying many different numbers, I found that 31° and 32° are my year-round optimal tilt angles -- both would generate an estimated 5,814 kWh per year.
Note: There's currently no way for the PVWatts Calculator to just tell you the optimal tilt angle. You'll just have to use trial and error. Also, the calculator does not give you the option to input seasonal or monthly tilt angle adjustments.
H/T to The Solar Nerd whose article taught me this solar tilt calculation method.
5. A Stanford Research Team's Tilt Angle Formulas
Our solar panel tilt calculator is based on a Stanford research paper .
The researchers behind it analyzed optimal solar tilt angles for all countries worldwide using PVWatts. Then, they produced two formulas to calculate the optimal fixed-tilt PV angle for any given location based on latitude.
What are these magical formulas, you ask?
If you live in the northern hemisphere (latitude > 0):
(Ί = latitude)
If you live in the southern hemisphere (latitude < 0):
There you have it:
A simple, research-backed way of calculating the optimal tilt angle of your solar panels.
Note: These are the formulas under the hood of our solar panel angle calculator at the top of the page .
Like I explained above, I used Google Maps to find my latitude.
Doing so, I learned that my latitude is 33.7°.
Because my latitude is greater than 0, I can use the first formula listed above to calculate my best solar panel tilt angle:
After busting out my calculator (and doing a quick refresher on the order of operations), I get the following:
My optimal year-round tilt angle: 28.6°
(Because our calculator uses these formulas, we got the same answer as our calculator.)
If I want to adjust my solar panels seasonally or monthly, I can add and subtract to this angle based on the rules of thumb described above.

Know your codes for solar mounting
By SPW | April 16, 2018
By Dan Felix, IronRidge training manager
Working in the solar industry necessitates understanding more than one type of code, unlike, for example, an electrician who may just need to know the National Electrical Code (NEC). Building codes (IBC), fire codes (IFC) and structural engineering codes (ASCE) also come into play when adding solar to an existing structure. Here are a few codes all solar installers should be familiar with when working on rooftop projects.
International Building Code
Flashings and attachments
The IBC states in article 1503.2 that “flashing shall be installed in such a manner so as to prevent moisture entering [âŠ] penetrations through the roof plane.” The IBC also states in article 1507.2.9 that “flashing shall be applied in accordance with this section and the asphalt shingle manufacturer’s printed instructions.”
To prevent moisture from damaging the roof or entering the structure, a sealant is typically placed in holes and underneath the flashing. To this end, the IBC code requires an attachment flashing and a sealant that meets the requirements of the roofing manufacturer.
Fire considerations
In article IBC 1509.7.2, it says that “rooftop-mounted PV systems must not diminish the fire classification of the roof system.”
In order to meet the IBC code here, one must ensure the system and equipment used have a UL fire-tested class rating that either matches or exceeds that of the existing roofing material.
Structural loading considerations
IBC section 3403 says “alterations to the existing building or structure shall be made to ensure that the existing building or structure together with the addition are no less conforming with the provisions of this code than the existing building or structure was prior to the addition.”
This means that when adding solar to an existing structure, an installer cannot exceed what the building or structure was originally engineered to support.
Each jurisdiction seems to enforce this code differently to make sure the roof is not overloaded. For example, here are a couple stances IronRidge has seen AHJs take:
- Some authorities are rigid: âThe maximum spacing of PV supports is stipulated to be twice the rafter spacing and alternating such that all rafters carry the proposed system.â
- Some authorities are flexible: â45 lbs has been used by some jurisdictions as a reasonable level, below which point loading of roof joists and trusses can be ignored.â
One should contact the local AHJ to understand the requirements for point-loading a system. And if in doubt, one can always contact a structural engineer to review the structure and the planned added weight of the proposed system.
One way to evenly distribute weight across a solar system is to stagger attachments to the structure. This is a best practice, since staggering attachments means there will be less weight on each rafter.
International Fire Code
The IFC states in article 605.11.3.2.1 that “modules should be located in a manner that provides access pathway for firefighters.” It also says in article 605.11.3.2.4 that “panels/modules installed shall be located no higher than 3 ft below the ridge to allow for fire department ventilation operations.”
Combined, these codes require a 3-ft clearance down from the ridge of a pitched roof to allow for fire departments to ventilate the building. Additionally, a clear 3-ft pathway needs to be available for firefighter access to the roof.

National Electrical Code
NEC 690 defines electrical safety requirements for PV systems.
Equipment grounding required: Exposed non-current-carrying metal parts of PV module frames, electrical equipment and conductor enclosures must be grounded.
Structure as equipment grounding conductor : Devices listed and identified for grounding the metal frames of solar modules or other equipment can bond exposed metal surfaces or other equipment to mounting structures. Metal mounting structures (other than building steel) used for grounding purposes should be identified as equipment-grounding conductors or have identified bonding jumpers or devices connected between the separate metal sections bonded to the grounding system.
PV mounting systems and devices: Devices and systems used for mounting PV modules that are also used to provide grounding of the module frames should be identified for the purpose of grounding solar panels.
Adjacent modules: Devices identified and listed for bonding the metal frames of PV modules can bond one panel to an adjacent one.
To ensure NEC requirements are met, one should follow the racking manufacturer’s torque specifications to tighten down all connection points. These connections provide the bonding and grounding for the system when assembled properly.
The UL listing of the racking system should be checked to make sure it has been tested and listed under UL 703 for the provision of bonding and grounding required within the codes.
It’s important to remember that all codes are written for protection from system failures that could risk life and property. National codes are not always adopted and enforced by all states or local jurisdictions, so solar installers should always research what exactly is required by each AHJ.

I have a question I’m putting solar panels on the rear side of my A-Frame house this full access to the front roof is there any reason I cannot cover the entire back side of my roof with shoulder panels my town code says there’s an exemption if they can access the front but the Solar Company is telling me that they cannot accommodate what I’m asking I’ve done the calculations it would afford me four more panels approximately 1,600 Watts and I have high usage
December 2, 2023 at 11:56 am
Are the installers required to follow the manufacturers instructions for the roof mounts during an installation? What requires them to do so?
February 24, 2023 at 4:54 pm
Great article!
Do walkway distances apply to attached patio awnings? I have a patio attached to the south facing rear side of my house. It is a sloped awning with asphalt shingle roof. Electrical runs in the interior to provide power for two ceiling fans. Would placement of panels require a 3ft walk way, or could I cover the entire surface with solar panels?
P.S I live in Northern California if this helps

Great article,
What happens if my solar installer did not meet NEC requirements to include rapid shutdown for a residential system installed in 2022?
December 30, 2022 at 9:29 am
What type of system was installed? Todays optimizers and microinverters comply with rapid shutdown requirements. So if your system is Enphase, or SolarEdge those components both comply with rapid shutdown.

We are building a 12 unit apt. in Minneapolis. we are being told we will need a 42″ para-pit wall surrounding our solar panel lay out. Which has a 4′ clearance pathway surrounding as opposed to our stamped and approved 38.5″ height para-pit wall? Does anyone have a clear interpretation of the code that dictates this height and at what para-pit clearances? Also being told solar panels are classified as mechanical not electric.

i was told that some fire departments will not attempt to fight a fire that is in a structure that has solar panels, do to the panels still being âactiveâ!
September 1, 2022 at 2:19 pm
In my experience as a consultant who does post mortem on fires, fire depts. do, in fact, substantially delay response due to lack of education of how the rapid shutdown systems function. The fire depts. need to train their personnel working around PV. There really is no excuse, the codes have gotten so good at mitigating fire risks that structure fires are such a rarity that fire departments fire for budget relevance to be equipped for the what-if scenarios. Then they get a structure fire and blame it on the PV that they couldn’t properly fight the fire.

Our Solar was installed but wiring from the panels were sliced together in the attic, taped with wire nuts but not placed in any junction boxes with covers. Does this meet code?
August 18, 2021 at 11:17 am
No, splices with wire nuts should be in a junction box. Also, if the wire is not in conduit in the attic, it should be ROMEX or similar cable, not just THHN wire. (The opposite is also true. Romex cannot go in conduit as the extra insulation will cause it to overheat.)
October 28, 2021 at 11:43 pm
NM cable (Romex) is designed to be run in conduit when protecting against physical damage. See NEC 334.15b

We recently contracted Titan Solar to install over 100 SilFab 300 panels to our terracotta tile roof. We inadvertently discovered that they had destroyed more than 300 tiles. This damage was due to 4 different crews and 16 different technicians stepping where they shouldn’t but also trying to drill into the concrete tiles. Now they think they can “Patch” the roof when these tiles no longer are produced. Can we get some advice on how to proceed?

Please reach out if you have not rectified this yet. We may be able to help.

Hello, i am a structural engineer out of Minneapolis that focusses primarily on rooftop solar panel installs. This particular question is from the 2018 IFC, specifically section 1204.3.3. A local building official is stating that one of the ventilation options in between sub arrays is required even if the sub arrays are fully contained within a 150ftx150ft area. My interpretation of the code suggests that sub arrays can be continuous for 150 feet. Any larger requires breaks for ventilation and/or interior pathways. In the event of a fire and if roof top operations are employed a fire fighter needs to be able to traverse on the roof quickly hence the needs for the breaks. However, some racking manufactures require breaks every 60-80 feet. Sometimes arrays must be broken up for ease of installation and or to avoid conduits or obstructions. Such is the case for a particular job right now where we have several small sub arrays in a cluster separated by 18″. From the start of the first array to the start of the last array does not exceed 150 feet. If the arrays were connected the official claims no pathways would be needed, but since they are we have to have a 4ft pathway with cut outs or an 8ft pathway between them. To me this is in excess of what the language in the code intended to require. Please require clarification or direct me to someone who can. Thank you
October 20, 2020 at 12:57 pm
I already have all the brackets in place and I’m getting ready to set the panels up there. It looks like they might be too close to the edge of my garage, but since it’s attached to the house, firefighters can have plenty of room to go up on all sides of the house roof and across the top. I want to be in code.
January 22, 2020 at 11:29 am
great page, i was looking for code on fire setbacks for no livable structures. carports and sheds. if there is any info i would greatly appreciate it.

The international fire code 605.11.3.2.4 that states âpanels/modules installed shall be located no higher than 3 ft below the ridge to allow for fire department ventilation operations.â significantly decreases the attractiveness of residential solar PV because it applies to both sides of a peaked roof. Our fire chief indicated his crews need access to the peak, would in our case use a ladder truck from the north side of house which is a drive with access for the truck, and needs ability to make a vent hole near the peak, but not necessarily on both sides of the peak. Our 45 degree south facing slope is ideal panel placement in Chicago area (latitude 41 degrees N) and could take a row of panels but for this rule. a flat roof abuts at 5 feet below the ridge, ruling out placement of panels lower on the sloped roof. I suggest this rule could give local fire chief’s latitude to determine which side of the peak they need clear.
May 26, 2018 at 3:06 pm
Fire classification needs to match what is required, not what is existing. Grounding and bonding is per UL 2703, not UL 703. Fire classification is based on moduke testing to UL 1793, and system testing per 2703. Technically, building steel can only be used for grounding if it is “conneced to the earth” by one of the methods described in NEC 250 (A) (1) or (2). Good article though

Your solar questions, answered..
Have solar questions? We have answers.
Dust and biofilms cause energy loss in solar panels and lower production by blocking sunlight from reaching the solar cells. Soil and algae build up on panels, and over time, harden on the surface. Soiling accumulation over time can significantly reduce the amount of energy produced by solar panels and the effect is additive over time. This is the reason that solar panels require periodic cleaning and maintenance. Soleeva Skye anti-soiling technology does the work for you.
Soleeva Skye anti-soiling technology is a glass surface treatment that can be chemically-engineered onto our solar panels. It is a unique, non-toxic, and industry-leading option available only to Soleeva Energy clients. It was developed by us to reduce the energy losses that occur when decreased sunlight reaches photovoltaic cells due to atmospheric soiling of solar panels.
The transparent surface treatment uses sunlight and moisture from the air to attack and break carbon bonds of the organic materials in dirt and convert them into inert gas. This makes greater sunlight available to the solar cells and a higher energy harvest from each solar panel. It also  eliminates the need to get onto the roof to clean the panels 2-3 times a year.
Solar panels generate more power when they are cool. Continuous high heat reduces solar panel efficiency as it affects the ability of the panel to harness electrons. It also causes solar panels to degrade more quickly. Self-cooling technology keeps power generation high while lengthening the life of the panels.
Soleevaâs patented methodology to keep solar panels cool and more energy productive is found in two products: Soleeva's S-1 air-cooled and S-2 liquid-cooled panels.
Our air-cooled modules are designed to mitigate thermal-induced electrical losses by dissipating solar heat into the air. This lowers the operating temperature and increases the thermal efficiency of the panel.
In similar fashion, our liquid-cooled modules also remove heat, but harvest the heat energy to generate hot water for use in homes and commercial businesses.  Our liquid cooled modules  have the highest energy harvest of any solar module on the market, producing a combined total energy harvest of 1.5 kW per module.
Soleeva has conducted continuing operational performance testing at the Renewable Energy Test Center (RETC) in Pahrump, Nevada. The purpose of this testing is to independently validate the performance of Soleevaâs panels in a controlled area where the panels are subject to a consistent and demanding environment. Real-time, unadjusted performance data is taken at the RETC Pahrump test facility and reported by RETC data servers. This data has confirmed the performance of Soleeva products at very high levels.
If your Soleeva solar system needs service, we will take care of it. We wonât push you to a manufacturer to resolve issues. Our customer service team is ready to help when and if you need it.

In practical terms, a modern 40ft monohull would have the space for around 1,200W of PV panels (cockpit arch, sprayhood top, deck), maybe 1,500W with the addition of a few portable panels for use at anchor. The 1,200W of fixed position solar array could produce around 360Ah on a sunny summer's day (zero shading) or more ...

Output Discrepancies. There's often confusion as to how much power you can harvest from a solar installation. A PV panel is nearly always advertised stating its theoretical peak output power (Pw), but in reality, on a sailboat where there are limited areas in which to mount them, they will more likely produce a maximum of 60 percent of their peak output if mounted horizontally and 80 percent ...
The simplest mounting method for rigid panels is directly to the deck using z-brackets, studs, or glue-on brackets. If mounting to frame above davits or a Bimini top run -inch x 2-inch aluminum bar crosswise under the panel, attach it to the factory-supplied mounting holes, and then attach with rail clamps or brackets (photos 1 & 2). Flat panels.
4. Attach the wires to a solar panel controller (see photo below) 5. Attach a new set of the same style of marine grade wires from the controller to your battery. 6. The red (positive) goes on the Positive terminal, the black (negative) goes on the Negative terminal. 7.
Nature Power Rigid. The nature power rigid is a large, powerful, single solar panel. If you are looking for the right panels to power your entire boat comfortably, these are the ones for you. They are very large so they will need a large flat surface area. alternatively, they can be hung vertically from rails.
Semi-Flexible Solar Panels. Semi-flexible solar panels offer a middle ground between traditional rigid and thin-film options. These panels feature a thin layer of solar cells embedded in a flexible plastic or polymer material. Semi-flexible panels can conform to curved surfaces, making them suitable for mounting on boat decks, cabins, or sails.

Tip: Use our solar panel tilt angle calculator at the top of the page to get an angle to use as your starting point in PVWatts. I did this and got 28.6° which I rounded up to 29°. 4. Note the estimated system output. At 29° tilt, this solar power system at my location would generate an estimated 5,809 kWh per year. 5.
National Electrical Code. NEC 690 defines electrical safety requirements for PV systems. Equipment grounding required: Exposed non-current-carrying metal parts of PV module frames, electrical equipment and conductor enclosures must be grounded. Structure as equipment grounding conductor: Devices listed and identified for grounding the metal ...
Soleeva CoolAir TM Technology. Solar panels need sunlight - but too much heat causes inefficiency. Soleeva's proprietary air-cooled technology lowers the operating temperature of our solar panels, which allow them to produce the highest energy output. This means our panels produce 15-25% more power over the lifetime of the panels.
