stable energy prices, and minimal equipment maintenance.
Utility inflation in the modern era is around 4.6% avg. With solar you'll have insanely low O&M so thats a nothing burger.
If you buy the equipment outright, you're in really good shape. If you finance it, it gets more difficult but at the same time, they do a ton of savings calcs in the background to do the financing. Typically big solar asset managers require a year 1 customer savings. Depending on the finance vehicle, there may be an escalator but without one the savings gap get big pretty quick as long as you have a decent system and favorable irradiance.

yep and the new PW3 is badass. I just wrapped up an IE review on them.

If you are in an area prone to hail, maybe a bad idea.
Here's a fun story...

The extent of the damage at a Scottsbluff solar farm that was heavily damaged in a hailstorm last week remains unknown.
“They’re still working through that process,” Grant Otten, spokesperson for the Nebraska Public Power District, which buys electricity from the solar farm, told Cowboy State Daily.
Cowboy State Daily reached out to Sol Systems, which financed and developed the project, but didn’t receive a response.
While some of the solar panels at the farm may be salvageable, as well as other equipment, it’s likely many of the panels will need to be discarded.
Even if solar panels aren’t destroyed by weather events, they gradually stop producing much electricity and reach the end of their lives in 20 to 30 years. By 2050, the International Renewable Energy Agency estimates that 78 million tons of solar panels will come to that point.

Recycling
While renewable energy proponents are pinning their hopes on recycling to deal with this coming deluge of e-waste from dead solar panels, only about 10% of them are recycled, and only a small portion of any single panel provides recoverable minerals.
B.F. Randall, who has a background in project development and finance, told Cowboy State Daily that a lot of people are under the impression that recycling a solar panel means you make a new solar panel.
“A solar panel has very little mineral content relative to the volume of the panel,” Randall said. “So, it's just not something that can be recycled in that sense.”

Why would you put holes into a good roof

Newer tier 1 modules are quite hail resistant. I have a 40kW system in west Texas thats been through dozens of hail storms with not a single issue. And while that's only my personal experience, I monitor enough systems across the US and it's territories that I can say with certainty it's a blow out of proportion talking point.
Comparing resi systems to utility ones where they many times use non-tier 1 garbage arse panels isn't really a good way to understand it.

This is honestly the most legitimate issue. I run a ground mount in WTX because I can.
I haven't put one on my house in Houston yet because 1) i'm waiting for someone to give me one for free lol and 2) I'm going to get real fricking picky about who i trust to come pop holes in my roof.

If the panels could be installed in the yard, then not a bad idea.
The idea of the added weight being on your room plus having to penetrate the roof doesn’t seem wise. I wouldn’t even allow my DTV dish installed on the roof of my new house. Had the installer use a stand/pole/post instead.
And how does it cost to replace/repair those panels? What about the materials in the panels?

They have to do load support calcs as part of the permitting process. If your roof can't handle it, it's not getting permitted for installation or interconnection.

They almost never fail and have insanely good warranties so factor in your replacement cost at basically zero.

Scam
First it costs like $20K.
Then it takes about 15 years to recoup via energy savings for what you spent on them.
Then you find out soar panels only last about 25 years, so you only get about 10 years of real savings before you have to buy brand new solar panels at $35K+ bc inflation has risen in the 25 years since you last bought solar panels.

If properly sized and installed it's the closest to seamless backup power you will find. Extremely low maintenance. User friendly adjustable preferences with real time monitoring data
We find it to be a seamless backup solution. We live in a smaller town and the electricity is not as reliable as in Houston. When we lose the grid here, most times we are not even aware. The Tesla app keeps track of that and has a report that I review every once in a while.
Another nice feature is that when a storm is forecast, Tesla will automatically ensure that the batteries are maxed out.
Finally, we recently (yesterday) started using Tesla's Energy company. They buy electricity on the open market during off peak hours and then sell it during peak times. We are hoping to make a few bucks from this as well.

Payout? How many years before you recoup your investment?
Posted on 7/14/23 at 1:55 pm to tigerstripedjacket
This is the argument. If you plan on living in the house for 30 years - good investment.

Nope. It depends on the system.

This is one of the many ways i know you have no clue what you're talking about. Please stop giving advice about something you know nothing about.

worth it for the right price. i install them in louisiana, can you get 10k savings at least vs standard rates if you mention TD in email to bigedlsu@yahoo.com

Is this their VPP program?

My experience:
- the 30% tax credit up front creates a huge windfall so you’re cash flow positive nearly the whole way through
- energy companies are scaling back buybacks greatly so you shouldn’t over size for what you generally use during the day. Ideally you use everything you generate.
- battery is expensive. If you want cheap back up power go with a portable generator.
I’m generally happy with what I have due to the tax credits. Without govt subsidies it’s a loser in most of the USA as that Infograph shows.
