One of the most common sustainable technologies I field questions about are Solar Panels. Typically, the two main questions are, are they worth it and how much trouble are they. And the answer to both is…depends.
Are they worth it? I’ll tell you I had solar panels and a deep cycle solar battery installed on my house a couple of years ago and when I did the math (and panels are now about 2/3 the cost they are now) I had a payback period of about 4 years with tax incentives, grants, and the savings on my electric bill. Now, my house was just about a perfect candidate with a south facing roof at just about the perfect pitch (I’ll admit I got lucky, the house predates me by about 100 years so I didn’t plan any of this) with a clear view of the sun. I also live in an area where electric prices are fairly outrageous (the town marks up electricity in lieu of raising taxes) and the state and federal grants and incentives aren’t all still available. Even with all that, it’s getting to the point where it’s almost a no-brainer. The cost of panels are dropping and while government incentives are dropping, energy rates are rising and private investors and companies are finding unique ways to turn profits off of these things. Speaking of Energy Rates, doing some research into ways that you can lower the cost will make a lot of difference to your everyday life, as well as saving you some money every month. Who wouldn’t want that? Most panels have a warranty of between 20-30 years, so even without the incentives, grants, and such, my panels would have paid for themselves well before they warranty expired. So my short answer is, yes, if you have a clear view of the sky to the south, it’s most likely worth it financially. If you have solar panels like us then you may be interested in monitoring just how well they are performing. You can do this by having a look at the different solar panel monitoring methods that are available to you.
