Residential Solar Installations

In the beginning, Westcoast Solar Energy would take on every simple residential project they could.

As the company grew into one of the leading solar companies in Sonoma County, the team became more excited about the larger, more challenging residential solar installations.

Hanging a ground mounted array off a cliff to maintain a million-dollar vineyard view, using our crew to provide power to a house without disturbing the formal gardens or a hybrid/off grid battery system for a remote bed and breakfast; these are the types of projects the Westcoast team is most qualified for and the most eager to be a part of.


  • This field is for validation purposes and should be left unchanged.

Residential projects receive a great deal of trickle-down technology from the larger, more advanced, uptime-critical commercial systems. This enables Westcoast’s engineers to look at projects differently. Without being handcuffed by a lack of equipment or specialized tooling, and being armed with the knowledge base and can-do attitude of years of design and engineering experience, Westcoast Solar Energy delivers projects that lesser operations deem too difficult or complicated.

Helping homeowners take advantage of solar energy to save money and help the environment remains a passion as residential projects present a unique blend of needs. Positive customer experience, liveability and aesthetics need to blend seamlessly with performance, energy savings and quality of installation for a true longevity-based project.

An almost limitless capability, expert installation teams and a commitment to positive customer experiences means a Westcoast Solar Energy residential system provides an unparalleled level of value. Westcoast Solar Energy residential customers benefit from an accurate process delivering unrivaled results.

Longevity Based Design

Reliability and longevity are the most important factors to consider in a solar design. A non-functioning solar array can quickly change from a valuable energy generating asset to a roof-mounted liability. PV technology has changed greatly over the past 10 years, but solid construction principles and professional electrical work has been around for generations. Simple things like properly locating electrical equipment, minimizing rooftop conduit runs, and using designs that reduce roof penetrations lead to solar arrays that function properly with little maintenance for decades. The solar arrays that Westcoast Solar Energy installs today have roots in the systems of the past. Over the years they have proven what works and what doesn’t.

Expert Site Surveys

Satellite images and remote measuring are now becoming commonplace in the solar industry. These techniques sacrifice accuracy for low upfront operational costs and can lead to installation problems, permitting and performance issues. Westcoast Solar Energy will not quote or install a project until a thorough site survey has been completed. During the survey, a member of our engineering team will measure all available space, evaluate the quality, strength and remaining life of the roof. They’ll work with you to map out conduit and equipment locations and evaluate the electrical system to see if it is safe and sized properly to accommodate a solar installation.

This is where residential projects get fun. Everyone wants a high-performance system, however, it needs to look good, too. WSE’s residential designers have completed thousands of custom designs and know how to blend the two seamlessly. The installation teams have the ability and tools to make every installation look great.

Simple Contracts

WSE contracts are simple, to the point and clear with the intention of installing your project for the price quoted. What you won’t find are loopholes, allowances, or “subject to engineering approval” clauses.

Installation Crews

Westcoast’s Installation crew members are long-term employees each with over 5 years experience. A commitment to quality means not paying the crew bonuses based on speed like other local solar companies in Sonoma County. The Westcoast crew is rewarded for positive customer experiences. The result is no compromises on installation quality whatsoever.


Throughout the entire installation process, the Operations team keeps you up to speed on the progress of your project. Communications containing plans for approval, permit status, installation schedules and daily crew reports while on-site ensure a smooth project and no surprises.
