Overview:
In the electrical portion of the survey, you will gather photos of the electrical equipment in and on the home and the space surrounding the equipment. The purpose of an electrical survey is to determine whether the existing electrical equipment can handle a solar installation, and how much space there is for additional solar equipment and wiring. For this reason, pictures that clearly show the area around the electrical equipment are key.
Surveying the main service panel
Surveying the utility meter (side house photos)
Marking the meter and main service panel on the roof map
Special cases regarding utility poles
Special cases regarding utility panels blocked by tamper tags
The Main Service Panel (MSP), also referred to as the breaker panel, is a distribution point for electrical circuits in the home. It can most often be found in the basement or in the garage but can be located in other rooms or outside as well. Before searching for it, ask the homeowner where it is located.
WHAT TO COLLECT
Photo of entire MSP, door closed
Photo of entire MSP, door open
Photos of ALL service labels inside
Photo of entire MSP with cover removed
Pull back photo 5' away
Close-up photos of the wiring
Close-up photo of main breaker rating
A 360° view of the room around the panel
You will need to remove the cover of the breaker panel (called the dead front cover) to take pictures of the internal wiring. The video below shows how to remove the cover, and the next page will provide examples of the photos we are looking for.
Safety Note:
While it is not an OSHA requirement, it is recommended by OSHA to use insulated rubber gloves, insulated screwdrivers, and rubber-soled shoes when removing the dead front cover of a breaker panel. These are not required by Exactus Energy, but as a subcontractor, you may choose to follow OSHA safety standards.
Before approaching a breaker panel, it is important to look out for:
Rust or corrosion
Wet areas around or on the panel
Mismatched screws that might have a pointed end and can pierce a wire
If you notice signs of water, please take a picture from far off and call us. Do not approach the panel.
Main Service Panel - Example Photos
See below for examples of the required photos for the main service panel (MSP). If you notice anything strange about the panel or the surrounding area, please take multiple photos to make sure we can properly analyze the electrical situation for the home.

For the photos with the cover off, make sure to collect at least 10 photos in total.
Please check for signs of damage around the meter and take pictures of anything that looks out of the ordinary
Do not approach a panel where you see signs of water
Do not open the panel if you noticed mismatched screws.
Common red flags:
Rust or oxidation
Signs of water
Frayed wires
Electrical (Utility) Meter next to the panel
In some homes, you will also find one or multiple sub-panels, which are a smaller version of the main service panel. You will have to ask the homeowner because it is not always located right next to the main panel. Please note some homeowners might not be aware of where their subpanels are located. As best practice, if there is a subpanel, hold up one finger and take a photo of the MSP, two fingers for the sub-panel, three fingers for a second sub-panel, and so on.
Pro-tip: If you see a breaker with a rating over 70 amp on the Main Service Panel, that's an indication there could be a subpanel present. If you notice this, you can ask the homeowner:
Based on what I'm seeing on your Main Service Panel, looks like there are other Electrical subpanels. Could you show me the panel?
Is there any subpanel present in your garage, basement, or service room?
Is there any subpanel present in the detached structure? (if applicable)
If the homeowner is unsure about it. Kindly ask him if he could give you access to either the basement or detached structure to do a quick search.
If there is a sub-panel, please gather the same photos as you would with a main service panel.
Below you can find some examples showing but not limited, to the types of subpanels you can find:
Subpanel 1
Subpanel 2
Subpanel 3
Subpanel 4
As part of the electrical survey, you will need to take pictures of the side of the house where the utility meter is located. Occasionally you will also find an electrical breaker and/or an external service panel on the outside of the house, and we would need pictures of that as well. This section will show you how to capture these photos.
WHAT TO GATHER
Close-up of the utility meter info
Photo 5' from the electrical meter
Photos of the entire wall
Photos 6' from the left and right
Photos above and below the meter
Close-up of external breaker (if there is one)
Photos of external service panel including wiring under the cover (if there is one)
Below are some examples of the photos that we need of the utility meter. Note that we have included one example photo for each category, but it is best to take more than one picture in case some turn out blurry.
Photos must be clear so we can read the labels
Photos of the surrounding area are great so the installers can see how much space they have to install connections
The first example is the photo on the right side, showing a close-up of the meter but we also need:
Around the Meter
Entire Wall
External Breaker Close-Up (if there is one)
In some homes, there will be an electrical shut-off switch outside (external circuit breaker). It is important to get a picture of this if you see one. If you aren't sure if the box is an external breaker, take a close-up picture just in case. You may need to raise the front cover to see the switch.
In some areas, it is common for the main service panel MSP and/or sub-panel to be located outside the home. These exterior service panels will be located near the utility meter.
In these cases, follow the same steps as explained previously for any MSP or sub-panel. See the examples below.
External Service Panel - Door Open
Labels - Close Up
Take a close-up of the label on the door AND any labels you see on the inside of the panel
Do not move any wires to access the inside labels - just do the best you can to get a clear shot
We need to be able to read the Main Amp rating on the label (ex: 150A) - please take really clear photos
Main Breaker CLOSE UP
The number on the main breaker must be clear
This photo is extremely important to determine the electrical capacity of the home. Please do not forget it!
Entire Panel - COVER OFF
Sometimes an external panel attached to the meter will appear to have tamper tags installed by the utility company. Please note this is rarely the case. Many panels have a trick to opening them. In the following case, a surveyor believed that the utility meter tamper tag prevented the opening of the panel. However, there was an additional latch that would grant access to that external electrical panel.
If you are ever unsure, and never cut a utility tag, please call the Exactus Energy support line so we can help you access an odd electrical panel. If there truly is a tamper tag please do the following:
Take ample photos of the utility tag and the panel
Advise the homeowner that we will be contacting the utility company for permission to remove the tamper tag
Call the Exactus support staff for further instruction
Sometimes the utility meter is located on a pole away from the house. For utility pole meters, please take the same pictures, but also write down the Utility Pole Number.

Take ground-level photos of where the wire leads to at the residence
After locating the electrical meter, the main service panel, and any sub-panels, it's very important to sketch them on the roof map. This way the electrical engineers can estimate how much wire is needed to run up to the solar panels. You can draw the map using a pen/pencil or using a markup app on your phone.
1. First draw an outline of the house from a bird's eye view. It helps to use Google Maps or drone photos to get an accurate picture of the layout.
2. Next, mark the front door or indicate the direction of north to show the orientation of the house.
3. Finally, mark the location of the main service panel, sub-panel, and electrical meter. Be sure to indicate B for the basement, 1F for the first floor, or G for the garage.
