This perspective is always so myopic to me. I say this as someone who doesn't make much money who's in the middle of a massive solar install (DIY). I made some simulations and a spreadsheet to work out all of the scenarios and I figured out that with a loan I can come out at monthly financing costs nearly exactly my electrical bill every month. That's right, I can have a 12 kWh battery backed 18 kW whole-home installation at no additional monthly cost.

The way that these discussions get contorted online will never make sense to me. The same people who make comments about ROI and it not making financial sense also have new car-loans on vehicles that depreciate catastrophically and are worth nearly nothing in 10 years. After 10 years my solar install will have been paid off for three years, I will get free electricity, and I will have the following benefits along the way:

Additional home value/equity

Backup power in case of grid problems or catastrophe.

Free fuel for my used battery electric vehicle. (compared to ~$200 a month in gas)

As close to zero carbon footprint as you can have in our contemporary world

And that's all assuming electricity prices stay the same. That's not even talking about how hydrocarbons are a very finite resource. Saying there's no "ROI" is looking at the situation like the only variable is your monthly expenses. It's the best decision anyone with a home who has the climate can possibly make. If you value your independence and personal security you'd be crazy to not do it. What would you pay, if you have the kind of money most people on these forums do, to ensure your home operates independent of external inputs? Imagine a new great depression? Or other such event?

That's the reality of life for most people outside of our little bubble of six figure earners. If it's a higher monthly price, it's a nonstarter.

>"Additional home value/equity"

I wouldn't be so sure of that. Solar is a massive maintenance liability that a majority of buyers will avoid. Fine if you find the right one willing to pay a premium, but how much more are they going to pay for an old system vs. installing their own?

[polairscience]

I'm not a six figure earner, and have never been close. Your mentality is not everyone's mentality. And there are many people, my neighbors and friends, who are willing to pay more for energy security and independence who are not in a bubble of six figure earners.

For your equity comment, it reads like astroturfing. Every single report with real-world data shows that it's positive equity and that homes with installations sell for more than those without. It's not a "vibe" I have, it's a cold hard fact. There's a million things you maintain when you own a house, and free energy is literally the easiest thing to want to maintain. Compare that to siding, or septic, or anything else....

Your comments aren't in good faith at all.

> Solar is a massive maintenance liability that a majority of buyers will avoid

My parents put up solar in 2005 when it was very expensive. The original panels, inverters, cables are all still there, nothing had to be replaced in the last 21 years. The only maintenance task is a recommended (not mandatory) yearly cleaning that is probably in the 300€ range and takes maybe 1h, but since 5 years they have 2x EVs and 2x Powerwalls and are self-sufficient for 80% of the year, so that cost is negligible. The area where they live also has enough rain that if they skip cleaning for 1 or 2 years, the average total output is still close to the max they can get.

> massive maintenance

What maintenance for solar panels? Please share your videos of oil changes on your solar panels.

As opposed to equipment for fossil fuel which (a) doesn't burn fuel (b) has no moving parts (c) doesn't have thousands of parts and therefore runs free of any maintenance forever?

I wonder where these kind of people come from and what kind of education they have? Even Pakistan seems far more technologically advanced, they've been rapidly deploying solar with no issues.

That's not at all true where I live (Seattle): the cost of a solar system goes almost straight over into home equity. Solar energy is a feature - a real selling point. No idea what maintenance liability you could have in mind; one can have panels cleaned once a year, for maximum output, but they still just work if you don't. Other than that there is literally nothing to maintain.

... Wait, which maintenance is this? You'll probably eventually have to replace the inverter (or, at least, solar panel warranties are normally considerably longer than inverter warranties), but that's probably about it.

(Theoretically you can get a minor efficiency improvement by cleaning them regularly, but it really is minor to the point of "arguably not worth doing at all" in most conditions.)

Can you cite sources please.

I’ve had my system in Canada for 2.5 years, flawless, not one second of maintenance.

Family in Australia have had systems for over 10 years with zero maintenance

Also electricity here is ore approved to increase by a minimum of 5% a year, so a solar install on a house is huge for equity. Most people here spend around $2k to $3k a year on heat. I spend $400.
