The True Cost of Utilizing Solar in San Diego

Cost savings of energy efficiency can pay for backup power.

There are a lot of variables surrounding the use of a solar power system, and you may have wondered if solar is a better option for your home. While a lot of talk has circulated in regards to the supposed benefits and value of solar, as well as overall function, there is good news for anyone residing within the San Diego, California area – we have calculated the variables of solar power for you.

Cost savings of energy efficiency can pay for backup power.
Would you buy 25 years of solar power based on your Last Year Use, knowing that lower cost energy efficiency solutions to replace the inefficient water pumps, A/C, incandescent lighting and 10 year old appliances can cut the system size in half? The up front cost savings of energy efficiency can pay for emergency backup power.

The power source of your entire household is one of the most important considerations of home ownership. And, rather than hanging you out to dry, we have resolved to answering the most important, nagging questions: “is solar worth it” and “what is it going to cost”. Rather than wasting hours upon hours playing detective, we have summed up the most important information you need in order to make an informed decision about solar, for your family.

The Initial Cost

For the average residential system, typically purchased within the San Diego area, a 6 kilowatt installation is recommended. For this article, we are going to utilize the available data in order to provide an initial overview of cost for as many curious people as possible. With this in mind, the upfront cost of installation generally starts around $19,200 before incentives. The total price is based on an average cost of $3.20 per watt.

Incentives of Solar

Once you take available federal tax credits into consideration, the total cost drops considerably – once the 26% discount is taken into account. The initial quote immediately drops to $14,200 with the aforementioned savings. The most important detail to take note of, is that the credit is for individuals who actually purchase their own solar system.

No doubt you have heard or seen advertisements from a variety of solar companies, offering leases, in addition to Power Purchase Agreements, if you find yourself in the market. The issue surrounding promotions such as these is that, because a separate company owns the solar system, the consumer will not receive the tax credit if they are leasing – the solar company does. These types of agreements typically mean, however, that the developer is solely responsible for the overall upkeep of the system, in addition to the financing arrangement and installation. The consumer is simply charged a fixed rate for their consumption of solar power.

Many leasing companies do not install open rack modules.
Many leasing companies do not install reverse tilt modules, pole mount, awning, carport or ground mount.

Because, realistically, families do not have $19,200 in cash at their disposal for the purchase of a new solar system, loan or leasing may be a viable option. The leasing situation isn’t much different when compared to that of a utility company, aside from the fact that the rates are a bit more affordable. Aside from the benefit of lower rates, the savings from leasing are consistently lower once compared to the outright purchase of your own solar power system by cash or loan. However, when a lease is your only option, it is worth time spent researching solar companies that offer a lease-to-own alternative to leasing. Benefits might include lower payments, in addition to benefits beyond the 26% federal tax credit, such as additional tax incentives.

Differences in Solar Energy Systems

When analyzing a typical solar system, the monthly average is 800 kWh (kilowatt hours). This number is based off of a 6kW system producing an annual average of 9,600 kWh in the first year. While these rates can change significantly with more advanced solar systems, which offer higher installed system capacity, these systems are able to produce 8% to 20% more kWh per watt. Along with the long-term savings increase, and a higher initial investment, homeowners will observe an overall decrease in length of pay off.

San Diego Utility Pricing System

As we watch rates continuing to climb throughout the San Diego area, the pricing system has integrated a slew of fundamental alterations. Even the way utility companies price power overall has faced significant changes, at least up until 2016. Before 2016, homes were based on a 4-tier pricing system in order to classify homes in a more affordable manner. Prior to 2017 it was changed to a 3-tier system and, currently, we stand at a 2-tier cost structure as rates continue to rise. “Super user” surcharges have also been imposed for households deemed beyond tier 2.

Annual Savings

Solar offers a significant advantage over tiered pricing systems, and assists in saving money on subsequent monthly bills. Considering how they are San Diego’s largest coastal and inland electricity providers; we have based our calculations on SDG&E’s residential pricing system.

Before installing a solar system, households typically consume an average of 800kWh per month, or an annual 9,600kWh. Because a residence generally consumes more power after installation, potential savings tend to range from 9,600 to 12,000kWh. Homeowners living within inland San Diego can expect, by our calculations, to save upwards of $4,000 each year. However, in coastal San Diego, the savings decreases a tad with the moderate coastal climate, topping out at $3,000 annually. Essentially, your solar system would pay for itself in around 3-4 years, assuming a 6% annual average increase in SDG&E utility rates.

A Bit More Consideration

Although this brief rundown only begins to illustrate the feasible savings presented by a new solar power system, savings may be influenced by additional factors. The size of your system, requiring a larger installation, offers further annual savings, and enables the system to make recompense for itself. Every homeowner, interested in solar, should take it upon themselves to study the topic further, before deciding to opt for a solar system.

Makello Research Assistant in UCSD ESYS Capstone

AuroraSolar solar design model energy analysis irridiance

I was going into my last quarter of undergrad at UCSD when I started interning at Makello. The internship was part of my Senior Project, and I enjoyed working with a diversely skilled team.  I worked with people with experience in many fields including software/electrical engineering, solar installation, non-profit organizations, management experience, and GIS systems all united by a common goal: clean energy.

I recently completed my B.S. in Environmental Systems and Earth Sciences with a minor in Marine Sciences. I am pursuing a career to combat climate change to preserve our planet as we know it, but there is also a part of me that feels a societal obligation to help elevate the standard of living (if they want it) for people who do not have equal access to opportunities such as education, community resources, healthy foods, etc. I believe we live in a society to take care of each other, and generally, disadvantaged communities could use additional resources, so I was excited to work with a company that works closely with non-profit organizations, especially non-profits in disadvantaged communities, such as Groundwork San Diego. I am thrilled to be in a position, right out of college, where I can help combat both social and environmental justice.

During my internship, we attended many events as both attendees and presenters, sometimes with Groundwork San Diego or our solar installation team. Examples of events were community activities, such as organized runs or home and garden shows, where we would provide information about electric vehicles and solar. We also attended car shows and electric vehicle focused events to stay current with new electric vehicle technology and to help explain their benefits to the public.

Part of my initial training was how to use solar design and cash flow analysis software, the site survey measurements and the customer’s goals to determine the Optimal System Size. I grew up doing home remodels and renovations during summers, so I enjoyed visiting different homes and seeing different styles of architecture and landscaping throughout San Diego. It was cool to see some existing solar arrays that customers had already installed too. It was also nice to be able to put a face to the customers whose proposals we were working on. 

Working on customer proposals and site surveys was my favorite part of the internship because it was a combination of computer design and modeling, hands on physical labor, and critical and analytical thinking. I still enjoy the same work, but now my Research Assistant position is 100% remote because we follow CDC guidelines to keep ourselves and our community safe. We used Makello’s software model to create the custom trade-off study proposals for each customer and automatically generate the correct price, ethically, without sales gimmicks.

Makello’s honesty and knowledge of energy efficiency, utility rates, solar power, electric vehicles, and battery storage, as well as assessing the needs of individual customers and their families, is what drives the high win rate with customer proposals.  On more than one occasion, customers wanted to purchase more solar than they needed, or wanted a battery because they believed it would increase cost savings. Using Makello’s model, our team showed that, in fact, a smaller solar system is needed if replacing inefficient appliances, or changing the times the appliances are in use.

I was excited to work on a diversely skilled team to create community pages for our website. We ended up creating a valuable tool with important information and graphics for San Diego communities. The pages had GIS Maps that displayed information on a variety of issues such as air quality, electric vehicle charging station locations, rebate eligibility, etc. We also included a list of different rebates and incentives for solar, electric vehicles and battery storage as well as information as to why they are beneficial to the environment and how they can save money.

With frequent fires and Santa Ana winds setting California ablaze we are in desperate need of emergency power supplies. The fires are coming dangerously close to our sources of electricity and threatening grid shut downs.

2 million Californians were left without power last week and this week that number could get even bigger. It is anticipated that up to 3 million California residents will be without power due to the fires north of LA and the Bay Area.

Having solar on your roof paired with energy storage gives you the freedom to have electricity in the event of an energy crisis or natural disaster.

Makello Aids NPOs & NGOs in Environmental Justice

EV Association of SD at Groundwork San Diego’s EarthLab

I met Charlie, the CEO and founder of Makello, during the summer while I was interning at Groundwork San Diego’s EarthLab in partnership with UC San Diego’s Center on Global Justice. While at the EarthLab, I was a college mentor for Groundwork’s High School Green Team. We were learning about electric vehicles, and Charlie was one of the guests who volunteered his time to come speak to us about the benefits, technology, and affordability of Plug-In Vehicles.

Charlie and other members of the Electric Vehicle Association of San Diego met with Groundwork San Diego’s High School Green Team.

Charlie volunteered his time on four occasions during the four week program. The second time I met him, he and Songxuan came to the EarthLab to do a solar and electric vehicle demonstration. We used solar ovens, metal sheets that reflect sunlight into a concentrated location, to heat up solar chili and cornbread. It was so good! He also gave us a quick presentation on “What to Know About Plug-In Vehicles”. The presentation was really cool because he demonstrated how the car, a MINI Countryman Plug-In Hybrid, could be used as a battery bank, using it to power the laptops and monitor, and explained how solar could charge up the car. We also got to look at the battery packs for his converted Plug-In Prius.

You don’t need a ton of solar to save money.

During his presentations to us, he acknowledged that he was a small business owner, but never tried to sell us on his products. Instead he explained how the technology worked, why the technology is more environmentally and community friendly, and how the technology could, in fact, be made affordable to families in disadvantaged communities. Solar and electric vehicle adoption contributes to safer, cleaner communities. Less greenhouse gases and smog are emitted from cars and power plants, leading to better air quality in communities.

Using the latest module technology has advantages.  Highest efficiency modules degrade slower and produce more power, resulting in a lower utility electric bill.

Lower efficiency modules occupy a larger area on the roof, reducing future expansion options, and they require more flashings, standoffs and maintenance to wash.

Dirty Little Secrets of the Solar Industry

Your roof could leak from a poor quality solar installation
Your roof could leak from a poor quality solar installation
Your roof could leak from a poor quality solar installation

The solar industry is in extreme competition with narrow margins.  Companies cut corners in workmanship quality and balance of system, to match lowest bids, while salespeople oversize systems to maximize commissions.  Whether you buy too much, or compromise the waterproofing to get to the lowest cost/watt, either way, you’re all wet.  Makello has a better way.

Optimal Cost Savings is a new concept for the solar industry.  The goal of 100% solar production vs use is an outdated strategy that does not address the current and future Time-Of-Use utility rates and the Net Energy Metering agreement with the utility.

Makello's Optimal Cost Savings is based on how you use power
Makello’s Optimal Cost Savings is based on how you use power.

In San Diego, utility electric cost savings is dependent on the time of day that power is produced and consumed.  Since every home has a unique pattern of utility electric use, an effective cost savings strategy must match solar production and energy storage to the historical and projected time-of-use interval data.  A detailed trade-off study of available site orientations and equipment options is necessary to identify the incremental costs and return on investment.

Makello’s Energy Analysis determines the optimal system for fastest payback, lowest cost and highest quality.  In almost all cases, the optimal sized solar system is much smaller and less expensive than you would expect.

Before you buy, ask yourself:

  • Does a large system size change the home aesthetics? Can I afford the upfront costs?  Will I relocate before the loan or lease ends?  Will the new home buyer value the energy production?
  • Have I received a proposal that offers alternative sizes and orientations to produce and store power for when I use it?  Has anyone provided an analysis which identifies the incremental cost factor, payback and return on investment for each additional module greater than optimal?
  • Would I trust a contractor or subcontractor, without proof of workmanship quality on my installation, knowing that the permit inspection does not include key areas on or under the roof, or below the array, where unseen conditions could void manufacturer warranties, compromise the roof structural integrity, or risk fire or roof leak, possibly years later?

Below are 4 topics to teach you how unethical solar installers can cut-corners where the homeowner and the permit inspector won’t see it, in order to lower the bid price. 

Poor quality installation techniques can only save money in the short term.  Eventually, the home repairs for potential water leak damage will outweigh any cost savings.

Topic 1)  Waterproofing – “Lag bolts in the center of rafters”.
For a cement tile roof, our process takes 1 installation team 2 days to complete and the competition does 2 installs per day with 1 team.

If we have access to the attic and the height of the attic ceiling is more than 36” tall, then we will install the lag bolts from the inside the attic.  That way we know that each lag bolt is securely fixed in the center of the rafter, and did not miss the rafter or split out the side. Our installation is durable to last a lifetime to protect the home and solar PV system from damage.

Other companies install lag bolts from the top of the roof; they do a hammer test on the roof to find a rafter, or they look at the eaves to see one end of the rafter, then they write marks on the roof, chalk a line and drill every 24” or 18” on center, hoping that they hit most of the rafters.  Even if an installer does hit a rafter, how will they know if they split the side of the rafter, which would compromise the structural integrity of the entire roof and cause it to sag over time? Or if they miss the rafter, then the 3.5” lagbolt will be sticking 3” out of the plywood; it might feel solid, but then when the wind comes it will shake the solar array and move the lag bolt up and down, widening the lag bolt hole and break the sealant caulking compound, eventually causing a drip leak, wood rot and termite problems, or worse, if a strong wind comes it could pull the entire solar array off of the roof!

Topic 2)  Waterproofing – “Sealant properly applied and cured”
If the industry top rated waterproofing sealant is misapplied or if the installer does not allow adequate time to cure before installing the solar PV arrays, you can expect water leak problems in the future.  

Our exclusive solar panel installer, Green Energy EPC does the job right.  After we install the lag bolts in the center of the rafters, we add the standoffs, flashing and sealant.  The sealant requires 24 hours to cure properly if the weather is cool or moist. On dry and hot days it can cure faster, but at the least, it should take 4 or 5 hours minimum to form a continuous bond seal between the rafter & lag bolt, lag bolt & flashing, flashing and tar-paper.  Green Energy EPC applies the M1 sealant properly in the required locations, and goes even beyond what is required, by placing 2 beads of sealant in a “n” or upside-down “U” shape on the flashing above the standoff, higher up on the roof, so that even if water is running towards where the flashing and standoff meet, it will be diverted away from the area by the “n” and around the area for many years to come.  After the sealant is applied, we leave the area for several hours to 24 hours, to allow the sealant proper time to cure before adding the rails and modules. The care and process takes extra time, and an extra day to roll the truck and bring back the crew, but it is worth it. We sleep well on rainy nights knowing the solar roof integration will be water safe.

Other companies are in a big hurry, with 1 team doing 2 installs in 1 day.  They routinely skip the sealant application or misapply the sealant so that it does not form a continuous bond.  They do not allow the sealant proper time to cure; they add the rails and modules, tighten the nuts, balance the array, tighten the nuts some more, move modules around and rebalance to make it square – all this activity is breaking the sealant bond that has not cured, introducing gaps which act as a channel for the water to drip inside the structure, eventually rotting the wood and tar paper, inviting termites to cause more damage.

Topic 3) Warranty: The condition of the roof, underlayment and supporting structure should be of sufficient condition to outlast the 25 year solar panels warranty.

A solar panel system installed securely and properly will last 25 – 30 years or longer.  If the condition of the roof, under-layment and supporting structure is questionable or poor at the time of installation, the roof might need to be replaced during the solar panel 25 year warranty period. 

Many solar companies and salespeople are willing to take the sale and cash the check, knowing that that condition of the site is insufficient to maintain the home waterproofing, and by the time the roof has a leak, they will be long gone.

Green Energy EPC inspects the condition of the roof and is honest with the owner about the longevity and expectations.  We will not install solar panels on a poor quality roof, if the tiles are worn through, or if the tar paper is torn, aged or missing.  Honesty and integrity is at the core of our quality installation. We would rather walk away from a deal to avoid potential problems and risks.  It is the ethical way of doing business. Sam Syed, President of Green Energy EPC teaches the ethics of solar panel installation and solar panel sales at our NABCEP accredited classes at Mira Costa College and at Cuyamaca College.  

Topic 4) Waterproofing – “Flashing requires careful shimming of the tiles in the row above”.

When installing roof flashing, it is imperative to take your time and not be in a hurry.  The proper way to insert a flashing is to use pry bars to carefully lift up the shingles higher on the roof, above the place where the flashing will be installed.  Each shingle or tile section is held to the roof by nails that penetrate the tar paper and plywood. If a tile is moved too quickly, the nail is pulled out of the hole, leaving an entry point for rain to drip through the roof.  If a tile is shimmed slowly, the nail end will remain in the hole and can be tapped back into place, blocking water penetration. In any case, if a nail is removed, it must be filled with sealant.

Solar installation companies that are in a hurry are likely to shim the tiles out too quickly and also to fail to fill the nail holes with sealant. Eventually the water will find it’s way to the drip hole, the wood will rot and cause more headaches for the homeowner.

Quality in manufacturing receives most of the attention in discussions with 1000s of San Diego residents, at our events and at our Energy Analysis appointments.  Why is so little attention paid to Quality Workmanship?

A high quality installation doesn’t happen by accident.  It starts with a NABCEP training curriculum, in the field mentorship, leadership that is reluctant to relinquish control or oversight until the trainee demonstrates excellence, and pledges to uphold highest standards in integrity, honesty and ethics.

There has to be a clear process and expectations, with strict adherence to safety procedures and protocols.  There has to be metrics, full-disclosure documentation, and follow through on all commitments. 

Any salesperson can say that they have highest quality.  How will you know the difference?  Read our guides to see for yourself:
