Free yourself from being dependent on the utility company and install a new solar system with the experts at Guthrie & Sons Heating, Cooling & Solar. 

Powered by SunPower

Living in Southern California, San Diego has an average of 262 days of sunshine per year. Powering your home with renewable energy is a no-brainer. Guthrie & Sons is proud to partner with SunPower, offering the most innovate and reliable solar power technology. With clean, minimalistic designs and an improved technology, SunPower panels have an extra layer within in the back side of each panel, allowing some of the sun’s light to be reflected back into the solar cell, which helps to generate even more energy.

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.

I requested quotes from 4 different businesses and received 4 different strategies on how to install mini split AC systems in our house. Guthrie & Sons Tech Vlad came up with the most logical and smart strategy on how to install the units on our house. It became clear that he is very knowledgeable and puts in actual thought on how to solve this installation. The Technician is highly trained, knowledgeable and has great soft skills. He answered all my questions well. The quote was competitive, however not the cheapest. The competence was far above the competition, hence we went with them. They were respectful with installation and machines have been running great a year later. There are minor issues with the units that are addressed a year later during the annual maintenance visit by another highly skilled Tech Johnatan. Overall, very happy with the performance of the units and the customer service. I recommend this company without a doubt!
