Solar Panels and Savings Accounts


Yesterday, I visited the MIT Museum with my sons and some of our friends.  It was quite fascinating learning about all of the history of technology as well as more recent research topics.

While there, I was watching a demonstration on alternative energy, specifically solar panels and hydrogen fuel cells.  It was quite interesting!


But the speaker also shared some of the economics of solar panels and that got me thinking.  He said that it would cost him about $35,000 net after tax credits to install panels on his roof in his suburban Boston home.

His electric bill is around $1,800 per year.

You might be thinking that it’s not worth it to spend $35k to save less than $2 per year.

Well, that’s 5.14% simple return per year!!!!  Tax free!!!!!

Where else can you get that kind of return today?  That’s a pretty good deal!

Now, I’m not suggesting that we all run out and get solar panels, though it would be really good for the environment.

How many people are taking advantage of opportunities to maximize earnings on their money?

And how many people are saving in a tax efficient way?

This example illustrates that there are opportunities to save (or earn) return that, on the surface, doesn’t look like it has anything to do with personal finance.

And then there’s the initial $35k investment.  This example works if you can afford to put down the $35k upfront.  Actually, it’s around $50k, but currently there are tax credits for solar installations which lower the final bill to the $35k.

If you borrow the $35k (really $50k), the interest expense will reduce your return.

So, the key would be to either have enough cash to be able to afford to do this, or borrow in a way that doesn’t really cost you anything.

Ultimately, wouldn’t you want to be able to do this, or make any other big purchase, without worry about money?

Most people either don’t have the cash.  Or they can borrow it, but at interest rates that wouldn’t make this an attractive investment.

So, how are you building up your capital so you can afford this?  Or, how can you borrow this money with minimal interest to do this?


Answer to last week’s trivia question – B – 19%.  Though it seems small, it still represents about 55 million Americans.  And that number is poised to increase dramatically in the future.

This week’s trivia question – According to the US Department of the Treasury, in fiscal year 2012 (started in Oct 2011), how much have Americans voluntarily donated to the government to reduce the debt.  Is it…

A – Zero! Who would volunteer to pay down the debt? We already pay enough in taxes!
B - $1.5 million
C - $2.4 million
D - $10.9 million
