Report: Solar savings through a SolarCity residential system
Having limited winter daylight hours combined with snow covered rooftops doesn’t make for good check out my huge solar savings conversation this month. But putting that aside, the overall economics behind my solar system tells a far greater story.
If you’ve been following along, you’ll recall that my journey with installing a SolarCity system dates back to late 2014. My system consists of 69 panels at 255W each for a total of 17.6kW (more specs on the system can be found on my Solar Generation page).
Solar Pricing
Massachusetts Electricity prices having been rising at approximately 9.5% year-over-year since 2008. When I started with SolarCity, my electricity price was set at $0.1627 per kWh including delivery, supply and taxes. Prices have continued to climb as seen on this chart.
The state went through a fun over-inflation and correction period in 2015, but the current rate I’m paying for electric is $0.1906 kWh with the best supplier I can find.
SolarCity sets their Power Purchase Agreement (PPA) prices based on your current electricity usage and comparable rates for the area that’s receiving their solar system. I had a number of options when I signed up including a variable rate, a fixed rate and an outright purchase but ended up opting for a 20-year fixed rate plan at $0.1420 kWh.
The way the PPA plan works is that I pay $0.1420 for every kWh generated by the SolarCity panels. The kWh they generate offsets the electricity I would consume. My savings initially worked out to be a difference of $0.0207 kWh or approximately 13% less. Recent savings have been in the $0.0486 kWh mark, or 25%, helped by the rise in electricity rates from utilities.
I incurred no installation or service costs when first setting up my SolarCity system, hence my entire cost for set up is based on the amount of power generated at $0.1420 kWh.

Solar Costs
In the last 22 months, I’ve generated a whopping 33.8 MWh (33,800 kWh) of power. My cost for that was $4,800. The SolarCity bill will fluctuate depending on the amount of daylight hour and weather conditions.
In that same period, my electric company reported that I used 23,800 kWh of power. Since the solar power offsets that amount, my actual power use for those 22 months was 57,600 kWh — I use a lot of power between my Tesla, pool, A/C and other electronics we have throughout the house.

About 59% of the power I need for my house and my Tesla comes from my SolarCity system. I wanted a system that could cover 100% of my needs but National Grid (local electric company) blocked that.
For the 23,800 kWh I purchased from the electric company, I paid $4,595, or $0.1930 kWh (averaged over the 22 months). My total electric cost (money paid to electric company and to SolarCity) for the 22 months was $9,395 or about $427/month.
While I consume a lot of power, 59% of it is provided by the sun.
Solar Savings
When I first signed up with SolarCity, they provided a $1,000 bonus if you registered for a solar system after buying a Tesla. That’s what I did and that’s how I received my $1,000 check form SolarCity.
They also had a referral program at the time which credited you with $250 for each person that signed up for a new system. I managed to get one referral and one more check from SolarCity.
All in all, I started 22 months ago with no money down and $1,250 in my pocket and a nice new solar system on my house. Not a bad start!
Had I purchased all my power from my electricity company at the average of $0.1930 kWh it would have cost me a total of $11,117. But thanks to SolarCity, my total cost was $9,395, so my savings was $1,722 over the 22 months. I expect savings and solar benefits will continue to grow over the next 20 years as the electric company continues to raise their rates.
SolarCity doesn’t fully capture the amount of savings that can be had through their system since the initial quote is based on current electricity rates, at the time of the quote. Rates climb over time especially in dense urban areas.
My savings thus far has been more than twice the amount SolarCity originally outlined! Now, if we add in the referral checks, my savings goes up to $2,972. The referrals don’t necessarily scale over time and may get updated so that needs to be factored into the equation.
Summary
For no money down and no risk, I’ve saved about $3,000 in just under 2 years (27% of what I would have paid) while generating green energy and taking load away from an already overloaded power grid.
When I did the math before signing up I knew the system would be a good deal and I’m very happy to see the results proving out. Since I’m on the power purchase program, I don’t have to worry about equipment depreciation, loss in solar cell effectiveness over time (I only pay for what they generate) or a whole slew of other things. By the time my plan is up, much better systems will be available.

Tesla owners propose interesting theory about Apple CarPlay and EV tax credit
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla is reportedly bracing for the integration of Apple’s well-known iOS automotive platform, CarPlay, into its vehicles after the company had avoided it for years.
However, now that it’s here, owners are more than clear that they do not want it, and they have their theories about why it’s on its way. Some believe it might have to do with the EV tax credit, or rather, the loss of it.
Owners are more interested in why Tesla is doing this now, especially considering that so many have been outspoken about the fact that they would not use it in favor of the company’s user interface (UI), which is extremely well done.
After Bloomberg reported that Tesla was working on Apple CarPlay integration, the reactions immediately started pouring in. From my perspective, having used both Apple CarPlay in two previous vehicles and going to Tesla’s in-house UI in my Model Y, both platforms definitely have their advantages.
However, Tesla’s UI just works with its vehicles, as it is intuitive and well-engineered for its cars specifically. Apple CarPlay was always good, but it was buggy at times, which could be attributed to the vehicle and not the software, and not as user-friendly, but that is subjective.
Nevertheless, upon the release of Bloomberg’s report, people immediately challenged the need for it:
Everyone thinks they need it. I would think that too if I didn’t know how good Tesla’s interface was. CarPlay is a crappy layer on top of crappy info-navs, and people think it’s an imperative because it provides a level of consistency from car to car. They have no clue how much…

How can it not be when the best engineers choose Tesla over Apple and Tesla’s core focus is auto vs Apple being mobile. It’s what Tesla does every day. It’s a side project for Apple. Still Apple is much better than any other auto OEM who attract lesser talent and make digital…

Some fans proposed an interesting point: What if Tesla is using CarPlay as a counter to losing the $7,500 EV tax credit? Perhaps it is an interesting way to attract customers who have not owned a Tesla before but are more interested in having a vehicle equipped with CarPlay?
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla has made a handful of moves to attract people to its cars after losing the tax credit. This could be a small but potentially mighty strategy that will pull some carbuyers to Tesla, especially now that the Apple CarPlay box is checked.

Investor's Corner
Ron Baron states Tesla and SpaceX are lifetime investments
Baron, one of Tesla’s longest-standing bulls, reiterated that his personal stake in the company remains fully intact even as volatility pressures the broader market.
Billionaire investor Ron Baron says he isn’t touching a single share of his personal Tesla holdings despite the recent selloff in the tech sector. Baron, one of Tesla’s longest-standing bulls, reiterated that his personal stake in the company remains fully intact even as volatility pressures the broader market.
Baron doubles down on Tesla
Speaking on CNBC’s Squawk Box, Baron stated that he is largely unfazed by the market downturn, describing his approach during the selloff as simply “looking” for opportunities. He emphasized that Tesla remains the centerpiece of his long-term strategy, recalling that although Baron Funds once sold 30% of its Tesla position due to client pressure, he personally refused to trim any of his personal holdings.
“We sold 30% for clients. I did not sell personally a single share,” he said. Baron’s exposure highlighted this stance, stating that roughly 40% of his personal net worth is invested in Tesla alone. The legendary investor stated that he has already made about $8 billion from Tesla from an investment of $400 million when he started, and believes that figure could rise fivefold over the next decade as the company scales its technology, manufacturing, and autonomy roadmap.
A lifelong investment
Baron’s commitment extends beyond Tesla. He stated that he also holds about 25% of his personal wealth in SpaceX and another 35% in Baron mutual funds, creating a highly concentrated portfolio built around Elon Musk–led companies. During the interview, Baron revisited a decades-old promise he made to his fund’s board when he sought approval to invest in publicly traded companies.
“I told the board, ‘If you let me invest a certain amount of money, then I will promise that I won’t sell any of my stock. I will be the last person out of the stock,’” he said. “I will not sell a single share of my shares until my clients sold 100% of their shares. … And I don’t expect to sell in my lifetime Tesla or SpaceX.”

Tesla CEO Elon Musk responds to Waymo’s 2,500-fleet milestone
While Tesla’s Robotaxi network is not yet on Waymo’s scale, Elon Musk has announced a number of aggressive targets for the service.
Elon Musk reacted sharply to Waymo’s latest milestone after the autonomous driving company revealed its fleet had grown to 2,500 robotaxis across five major U.S. regions.
As per Musk, the milestone is notable, but the numbers could still be improved.
“Rookie numbers”
Waymo disclosed that its current robotaxi fleet includes 1,000 vehicles in the San Francisco Bay Area, 700 in Los Angeles, 500 in Phoenix, 200 in Austin, and 100 in Atlanta, bringing the total to 2,500 units.
When industry watcher Sawyer Merritt shared the numbers on X, Musk replied with a two-word jab: “Rookie numbers,” he wrote in a post on X, highlighting Tesla’s intention to challenge and overtake Waymo’s scale with its own Robotaxi fleet.
While Tesla’s Robotaxi network is not yet on Waymo’s scale, Elon Musk has announced a number of aggressive targets for the service. During the third quarter earnings call, he confirmed that the company expects to remove safety drivers from large parts of Austin by year-end, marking the biggest operational step forward for Tesla’s autonomous program to date.
Tesla targets major Robotaxi expansions
Tesla’s Robotaxi pilot remains in its early phases, but Musk recently revealed that major deployments are coming soon. During his appearance on the All-In podcast, Musk said Tesla is pushing to scale its autonomous fleet to 1,000 cars in the Bay Area and 500 cars in Austin by the end of the year.
“We’re scaling up the number of cars to, what happens if you have a thousand cars? Probably we’ll have a thousand cars or more in the Bay Area by the end of this year, probably 500 or more in the greater Austin area,” Musk said.
With just two months left in Q4 2025, Tesla’s autonomous driving teams will face a compressed timeline to hit those targets. Musk, however, has maintained that Robotaxi growth is central to Tesla’s valuation and long-term competitiveness.
