Tesla Solar Roof vs Solar Panels: Which is Worth It?

I spoke to 2 installers in the Ohio area about the Solar Roof. Both quoted me prices around $180k which is about half the value of my home. So there was just no way to justify that cost.

I think it is because the Solar Roof wing of Telsa is terrible. I signed a contract for a roof, heard nothing for months, then got an email saying the cost was increasing by more than 50% without anyone ever coming out to my house. I decided to just cancel.

That point about being an early adopter Matt brought up was a VERY VERY GOOD point. Roof stuff isn't a phone or a game console, it's a very long term "investment" (it's not REALLY an investment, but you get what I'm going for here). It has to be reliable, it has to be easy to either replace or maintain, it has to last a long time.

I made the decision 11 years ago to go with a metal roof with standard sized frameless panels. I saw these advantages: 1) fewer connections in each string 2) larger gap between roof and panel, giving better ventilation, cooling and therefore efficency 3) more choice in the market using standard sized panels and better efficiency. 4) fewer panels and therefore easier to replace/maintain. I bought 85 panels + 2 spares. One panel shattered on install - not a problem, had a spare on site so i now have 1 spare panel. 5) the metal roof below is more like factory roofing with a repeating trapeze ridge/trough profile. Cheap, lightweight, long lasting and you don't see it because its behind the PV array. In terms of aesthetics i chose a south facing monopitched roof at 35 degrees. Basically a large rectangle covered by a 5 x 17 PV panel grid with no through entries (chimneys, windows, ventilation etc.) Looks great. The house is also box form below the roof - better for surface area to volume ratio and easier to acheive passive house rating than a complex H shape with a correspondingly complex roof shape. The panels were 220 Watt. Modern panels of the same size are 440 now. I will replace them in 4 or 5 years - the replacement will be easy - we can use the existing aluminium subframe and external fixations - no new drilling into the roof will be required.

As a solar service technician, you absolutely nailed it with your reasoning. Servicing is a huge consideration that would make me steer people away from Tesla products by default. Non-standard parts combined with only being able to get service from a single place is an enormous gamble.

After watching Mr. Brownlee's video, I contacted Tesla and received the contact information of a local installer. Our house is much smaller than Mr. Brownlee's home, so I figured we might be able to afford it. The quote came back at about 25% more than what Mr. Brownlee paid! It was over a half of the value of our house. Needless to say, it immediately fell outside of our budget.

Very interesting. I didn't know the prices were so similar.

EXCELLENT report Matt! 100% agree on all you said! I did not get because they are opaque about performance (besides no installers in my area). To add, your comment about "very personal decision" is key. I tell anyone interested there is NO "one size fits all".

I can tell you why I didn't get a Tesla solar roof. They didn't deliver. They quoted me and gave me an estimate of 13-18 weeks for install. 12 weeks in they cancelled my order and told me to resubmit through a local roofer they contracted with. The price went up 325% and the installation timeline was then estimated at 48-52 months. So my system price went from $110k with install in 2021 to $365k with install in 2024-2025. I got a standing seam metal roof for $35k installed within a month of contract signing. My solar system was $65, installed 12 weeks after signing, 2 weeks early. Installation was completed in 3 days, and PSE approved tying it into the network only 9 days later.

We have 12 year old panels. 4 have hail damage. Even though they are still working, we decided to replece the entire array. We use bet metering rather than batteries and are net $0. We are upgrading to new and fewer panels for the same kw this spring. The older panels paid for themselves ib 7 years we expect the new array to do so in 30 months. Love them. Can not imagine doing this upgrade with roof tiles.

So many don't think about utilizing solar panels as a carport roof, or awning, or shed roof . They don't always have to be mounted on the roof of the home

I recently got a quote for a Tesla solar roof, and my decision to not do it was based on two factors: cost (200k) and the low confidence/trust in the installer. 18kW system with 3 powerwalls & Span...$200k! 😢 The installer is the only option in the area. Ended up continuing the dream without taking the next step.

Rich people things.

Two years ago we tried to get a Tesla solar roof installed... it was a horror story of "no refund for you" and incompetent installers. They still owe us for preparation costs. They doubled the cost of the roof AFTER we had a signed contract, so we are now part of a class action to try and recover our preparation costs. At one point Tesla told us they would reimburse us, but that was two years ago. I drive a Model 3 and have plenty of Tesla stock, but the solar roof is not a product I would recommend.

A 'bug' that just happens to tell customers their tech is twice as effective as it is, and which has to be fixed for each individual customer rather than as one big firmware push.

Overall costs for both roofs and systems are ridiculous, I'm kind of amazed at how much you both paid. Both of you have been taken for an absolute ride.

In South Africa, our 2.9Kw 48v system, with 105A Lithium Battery and Inverter, cost us R56 000 in total, about $2,500. Granted my brother in law and myself did all the work, excluding the installation of the electrical switch board, linking our system to the grid and checking/certification of our system by a certified electrician, required by our local municipality and for insurance purposes, but paying for that is included in the cost above. Took us two years to fully pay for the system out of our savings

One thing that isn't considered is the Home Owner Association rules. Currently, our area has legislation drafted that will restrict HOA's from preventing Solar installations. We'll see if it passes.

Those prices are crazy expensive when compared what Im paying over here in the EU. Im getting next week 10 KW solar panels with 11 KW EV charger with installation for 10k EUR. On top of that Ill get 50% off of that price subsidized from the government by the end of this year. Im really happy with this deal :)
