How do we make solar work and why, part 2

In 2010, the average annual electricity consumption for a U.S. residential utility customer was 11,496 kWh, an average of 958 kilowatt hours (kWh) per month. Tennessee had the highest annual consumption at 16,716 kWh and Maine the lowest at 6,252 kWh.

Using $5.00 per watt as a basis for calculating installation costs, each system costs $37,000 to install, excluding all rebates and tax credits for a 1000 kWh system, just above the national average 958 kWh used.

  That $90,000,000,000.00 that was thrown at the solar companies by the U.S. government? You know, the companies that went bankrupt? That $90B would have installed 1000 kWh self sufficient solar systems into 2,432,432.43 homes. Moreover, that economy of scale would have likely reduced the per house cost.That's monthly electrical savings of about $243,243,243.24, or $2,918,928,918.88 per year total, a payback of 30.83 years, the average mortgage length.

So we see a benefit for the home owner, what benefit for all the other homes, people that did not receive the government money for self sufficient electric panels?

Lower electric rates due to the fact that many of these installs will dump power into the grid. More reliable electrical service. A drop in solar system prices. Less dependence on foreign energy, which enhances national security. Cleaner air and water. Jobs.

On jobs, that could be on the order of about 100,000 jobs. That is factored at 1000 companies, (20 per state), 100 jobs per company completing 10 installs per company per week for 2.43 years.

Let's talk some more about jobs, this time on the manufacturing side.
During the last solar "boom" (or bust) in the US, the vast majority of solar panels were coming from overseas, mostly from China, who, with their cheap labor can manufacture goods at a fraction of the cost that we can domestically. Since the solar bust there have been firms in China that have gone out of business for lack of sales.
Now, if we're talking about 2 million plus homes getting solar panels installed, then economy of scale should kick in on the manufacturing side, making solar panels affordably made domestically. That too equates to many more jobs. Thousands, potentially.
Inverters as well. Frames, concrete tiles, wires, maintenance, the list goes on.

So if the homeowner is given the money for the install based on:
1) their house is ideally situated to take full advantage of the solar installation.
2) on the caveat that they will lose $50.00 a month, $600.00 a year in their nominal tax deduction. Why not $1200 a year? Because they need incentive to agree to the install and structural changes in the house, but also due to the fact that many, if not all, insurance companies will charge the homeowner additional monies for their coverage because of the solar panels. So offset that cost by $50.00 a month.

"Well, if they aren't really gaining anything, what's the incentive?" you may ask.

It's the same incentive that people who did not get the panels have in allowing their tax money to be given to the people who got the panel installations, lower electrical rates, more reliable electrical service, a drop in solar system prices, less dependence on foreign energy, which enhances national security, cleaner air and water, and jobs, plus the feel good benefit of doing something good for our planet and our children.

It's not for everyone, for certain, but I think the benefits are very definitely worth it, for the economy, national security, and cleaner energy.
