Our Solar Installation Process

STEP ONE

DETERMINING SYSTEM SIZE

We’ll first ask you to provide us with a copy of your utility bill so we can determine your expected energy usage. We will also ask if you plan on making home improvement upgrades that may affect your usage, such as a new heating and air system or a new EV charger.

The size of your solar system will be determined by your energy usage. We want to be sure to size your system a little more than what your home typically consumes.

STEP TWO

SITE SURVEY

After we determine the proper system size for your family’s needs, we will come out and conduct a site survey. During a site survey, we’ll do an inspection of the home, evaluate the layout of the electrical wiring, and determine a plan of action for the installation. 

STEP THREE

INSTALLATION PROCESS

Depending on the size of your solar system, the installation typically only takes one day. Our certified solar technicians will first start with precisely measuring your roof and installing the racks which the panels will lay on. Next, the electrical wiring will be installed and connected to your electrical panel. Finally, your solar panels will be set into place on the racks. 

STEP FOUR

FINAL PERMITS AND
APPROVAL TO OPERATE

After your solar system is installed and before you start reaping the benefits, you must receive your final permit from the county and a final approval from the utility company to operate your system. 

Rest assured, we will take care of the final permitting and approval process with the utility company on your behalf.

 

EV Charger Installation

With gas prices on the rise, San Diego homeowners are turning to electric cars. Enjoy the convenience of charging your vehicle at home with a residential EV charger. 

Book an appointment for a quote to install your EV charger. 

Battery Back Up

Pair your solar system with a battery back up from Guthrie & Sons. When you have a power outage, your battery back up system allows you to control which appliances you want to remain powered. The next time a storm rolls through, you’ll have peace of mind knowing you can continue powering your appliances.

Anthony was very professional and communicative. He was easy to work with in setting up my hear pump installation project. I really appreciated the fact that he wasn't pushing a "hard sell" as some representatives from other companies did. When I had questions an needed quote options he was super-responsive and helpful. Great experience!When Carson, Isaiah, and Israel came your to perform the work, they were punctual, friendly, and respectful. When I expressed concerns or had questions, they addressed them immediately and effectively. Their work was outstanding, the job looks great and the system works well. I have already recommended Guthrie & Sons to other people.Thanks, again, for everything.

We’ve worked with a few Heating and Air company’s in the past at this was far and away the best we’ve worked with.

The removal of the old direct Heating and ducting went without a hitch. The installation of the new air conditioning and heating unit went very smoothly and I was impressed with every one of the workers. They were friendly and very knowledgeable. They were well equipped to deal with any process problems. I give five stars for this group.As part of the installation contract, Guthrie and Sons sent a worker named Wayne to replace the filter and check our air conditioning condenser. He was friendly and knowledgeable and even slipped on the covers over his shoes as he came through the house. The work was performed very quickly. Another five star performance by Guthrie and Sons.Zack visited today for yearly maintenance. Filter changed out and the unit is working optimally. We'll done.Daniel, this morning, replaced the filter and verified the furnace is in working order and providing proper heat throughout our home. Another skilled and friendly 5 star visit.

Your technician, Jonathan Santana was awesome. My husband was not home and Jonathan was very understanding. Even though there was a mix up with the service connection from Rheem, Jonathan assisted without hesitation. His help made my follow up conversation with Rheem much more productive. Please thank Jonathan for me.Best regards, Lisa
