All forms of energy generation produce some waste or pollution, it is disingenuous to only criticize solar panels that have a 20+ year life and produce minimal waste compared to the ongoing pollution of most other energy generation.
Please define "minimal waste" and show your work.

Yet again you just poke and no solution or proof of your claims. That is not a plan either. Try to make a contribution to the conversation instead of just being a PITA.

All power generation has some pollution - solar is "minimal" in relation to the alternatives. From 2011 report "Comparison of Lifecycle Greenhouse Gas Emissions of Various Electricity Generation Sources"

- Solar is listed at 85 tons of carbon dioxide equivalent (CO2e) per gigawatt-hour (GWh)
- Natural gas came in at 499 CO2e/GWh
- Coal was 888 CO2e/GWh.

You are the one asserting that solar is "dirty" without any proof or quantifying in relation to the alternatives.

Do you assert that solar panels do not contain toxic materials? A careful reading of my comment would have shown that I was not referring to CO2.

According to cancer biologist David H. Nguyen, PhD, toxic chemicals in solar panels include cadmium telluride, copper indium selenide, cadmium gallium (di)selenide, copper indium gallium (di)selenide, hexafluoroethane, lead, and polyvinyl fluoride. Silicon tetrachloride, a byproduct of producing crystalline silicon, is also highly toxic.

I did nothing of the sort but again you provide no data you still have made no verifiable claim - just poke at others. What you are implying is that solar is more impact to the environment but provide no proof.

Maybe this will help - Compare pollution from solar to the most used alternatives such as NG and coal - show your work.

Manufacturing is not the source of environmental pollution because can be contained and reused for the next panel or until disposed of properly. Highly toxic does not mean environmentally unfriendly, many manufacturing processes use toxic cancer causing chemicals in their process. On the other hand, power plants spew cancer causing chemicals into the environment that is not contained.

Many retail products and things used every day are technically cancer causing - here is CA list of Cancer causing chemicals - there are over 1000 items on the list - many of which are in everyday products. Cadmium, which you listed, is found naturally in things like fish and leafy vegetables. As a matter of fact, most of what you list like cadmium, copper, lead and fluoride are present in many foods - some are even added to water treatment and vitamins.

I will give you some help to start - power plants are the biggest releasers of many toxic chemicals into the environment - they release heavy metals into the air such as cobalt, mercury and arsenic, organics such as dichloromethane and formaldehyde and other materials such as friable asbestos and fluoride. All of these are cancer causing.

I thought "Dueling Banjos" was deadly but now we got dueling chemicals. OMG!

Solar cells are pretty much benign. Basically sand. And the additives can be removed or simply buried.

To Worldclass...

The time of solar power generation is upon us. And at this point any good dealer will be fine. Try checking on next door for people in your neighborhood who have a successful installation.

Note the actual issue is not whether to but when. The deal is reasonably profitable now...but it is getting a lot better. We have decided to hold off to 2023-2025. Take a look at some of the cost charts and project out...when is good enough. We also suffer from maturity so we know we cannot wait forever. In fact scheming to let the kids take care of the cost when the estate is settled.

Once I realized that I'm basically spending my heirs' inheritances, purchases are much less stressful to me.

NV Energy has net metering so if you send energy back to the grid they pay you 90 cents to the dollar. I am planning to install a swamp cooler tied into my A/C ductwork so that I can switch between A/C and swamp cooler depending on the humidity. Cost of swamp cooler and ductwork install would pay back in a year of net metering, and I figure to get back at least $500 a year in net metering if I use the swamp cooler most of the time.......kinda worried though, I've never seen this much cloudy days in the past year then the years before.

Better to buy than lease.
I went with Titan as well. I have mixed feelings about them though. I read all the 5-star reviews for Sol-Up and I genuinely can't say I had the same experience with Titan. The biggest complains people have about Titan are complaints I don't have. Panels were installed fine, the installers were great. All inspection tests passed. What I dislike about Titan is how they market themselves. They rely on affiliate marketing/franchise marketing. In other words, you and your wife or best friend could partner up, create a business name, then sell Titan's solar panels. Titan does not seem to have their own sales team. They allow other people to promote their products. The biggest problem with this is upholding standards and quality. Based on my experience, the communication between Titan and the sales rep I worked with could have been a lot better. But I will give credit where credit is due. All of my questions were answered and the process was pretty smooth. Titan is rated in the top 5 (above Sol Up) in terms of the top roof contractors in the US. NV Energy was fricken slow to inspect the panels and give me the Permission to Operate status though. I'll give NV Energy 1 star lol.
