I have been getting enough questions from the blog readers and neighbors that it is time to do a frequently asked questions list.  I have divided the common questions into four groups: practical questions, financial questions, technology questions, project questions and philosophical questions.  Here is the master list of questions:

Once you have a basic equipment list, you can take a more detailed look at the costs and financing alternatives. As discussed in the posts on state incentives and federal incentives, there are a number of programs in place to ease the cost burden of paying for all this exotic and expensive equipment. And there are a number of different ways you can go about paying for it.

Below is a diagram outlining the basic decisions, courtesy of our installer Independent Power Systems.

Once you’ve determined your site is viable, the next set of questions surround what your system will cost.  The first step in assessing this is looking at your historical energy consumption from past power bills (or your account summary on the electric company’s website) to get a sense of what your annual consumption and expenditure is.  Next you look at the amount of roof space available for panels and the expected production of those panels given the site orientation.  Now you have the target, and a sense of the resources available to meet it.

Once the economic arguments grip you, the next question you have to face is whether your site is appropriate.  This is determined by a site assessment.  Free site assessments are commonly offered by solar installation companies, and they are your first real opportunity to interact with and evaluate a prospective solar installer.  The company I had chosen to work with was called Independent Power Systems.  I chose IPS for four reasons:

After reviewing the regulatory situation for solar power in Massachusetts, I looked at the federal side.  On the national front, I learned that, on top of the Massachusetts State incentives, there is also a very decently-sized federal tax incentive, which can offset as much as a third of the system cost in the form of tax credits over a five year period.

So after letting this dream of going solar rest for a few years, I finally got things cooking again last Spring (2011) as a result of discussions with a friend who was in the tortuous process of building a LEED Platinum-certified house not far from mine. Heads-up: this is one of two wonky posts without much of a narrative thread – bear with me.

An engineer by training and a thoughtful and deliberative guy by temperament, my friend had put a great deal of careful research effort into both the consumption and the production of power for his house. What got me excited was his overview of the recent changes hitting the market.

I’ll never be able to explain my deep and abiding fascination with photovoltaic cells.  Most kids used big magnifying glasses and bright sun to burn leaves or ants.  I used them to make my solar-powered toys go faster.  Ever since those initial experiments in the early 1970s, my fascination has steadily grown.  Solar calculators.  Solar watches.  Solar chargers.  Given how crude the technology was at the time, and how my expectations always crept forward, every device was inevitably a little short of the performance I had hoped for.

But I never lost interest,…
