I’ve seen a lot of solar panels sprouting on Levittown roofs lately. It caused me to wonder if in the not-too-distant future, we will be seeing a lot more sunlight reflecting off rooftops which would give a whole new perspective to such classic images of Levittown.

Solar panels have become much more efficient over the past few decades and costs have dropped at the same time. When a solidly middle-class area like Levittown moves in the direction of solar, it’s a safe bet that the technology has taken root.

I have been watching the development of the technology from a distance for several years with the expectation that I would pull the trigger someday. But there were other priorities; replace windows, re-insulate, upgrade the HVAC, and transition to efficient appliances. Oh yes, there was also my favorite oak tree that towered above the house and cast shade on my roof which I was reluctant to remove.

After several years and with other projects now complete, I started to think about solar panels again. Multiple storms took down two trees that narrowly missed the house and I began to watch that favorite oak more closely. When I saw it rocking at the base in a subsequent storm, I knew it was time. Removal of that tree opened up the possibility of solar for my house. One door closed, another opened. Now nearly a year later, I can say that I am thrilled to open up an energy bill with a zero (0) balance due.

As a homeowner, there are several things to think about for a solar application. Here are a few to consider:

  • Levitt planted a lot of trees, many of which are now 60+ years old and tall. Look up at your roof throughout a sunny day and see if, like my oak tree, any cast shadows on your roof. If they do and shading is significant, you will have a decision to make.
  • Consider the age of your roof shingles. Solar panels will be on the roof for many years and you don’t want to put new panels over old shingles and have to remove and re-install them to re-shingle your roof. (Note that some solar companies have relationships with roofing companies and can do both.)
  • Hire a pro who can evaluate your home and site, guide you through the process, install, and commission the system. It is a multi-step approval process ultimately controlled by PECO in our area. A pro can navigate the project through.
  • Electrical work is required to integrate the solar installation into the house electrical system. Now is the time to add a circuit for charging the electric car you have been thinking about.

Good luck with your project.

My sister did a great solar project for her lawn equipment that now does away with all of her gas-powered tools.
