I continue to be amazed at tradeshows how attracted attendees are to photovoltaic (PV) products. It is admittedly an exciting technology and I saw this again at the Greenbuild and the International Builders’ Shows. At this past IBS show, our Builders’ Resource Center answered many questions on many topics but clearly the most interest was again regarding integrated photovoltaic roofing and PV panels.
I guess what I find so amazing is how much time people will dedicate to evaluating the return on investment (ROI) for PV while remaining so unwilling to spend even a little effort going after low hanging fruit that might not be as exciting or visible. PV can be a good investment for many folks but it could be a great investment if they improved their baseline consumption first.
Insulate, tighten up that ductwork and envelope while ensuring proper fresh air and then the same PV investment can go from providing say 50 percent of your power needs to providing 75 percent. There’s an old African proverb that says: “if you want to go fast go alone but if you want to go far go together.” Nothing could be truer in a situation such as this. Every little effort you make can combine to have an impact greater than the sum of the parts.
Another thing I often hear during trade show discussions about solar is that folks are going to wait a little longer until they get into the PV roofing (they have a new roof they don’t want to disturb just yet, they are waiting for the right client to force their hand, they heard that prices are going to keep dropping as more folks get into it, etc…). I understand. It’s not a small investment and so it should be done with prudence.
But…. adding insulation and improving the building envelope need not wait. Material prices for these types of products are near historic lows and labor is trained, willing, and eager to do the job. You will begin saving money on your energy bill immediately and perhaps your new cash flow properties will actually allow you to get that super sexy solar even sooner.
