Solar Resources

Are you thinking about solar photovoltaics for your home, farm, or business? You’re not alone!

Solar photovoltaic (or PV) used to be just for “early adopters”, but not anymore. It’s a mature technology that has come down in price so fast in the past 4 years that, as an investment, it can provide better returns than the stock market — even if you need a loan to finance it.

We’ve created this resource to help walk you through the process of going solar. Please be sure to contact us with any questions — we are here to help you go solar!

The bottom line? Here’s a quick and dirty why now is a good time to consider solar PV, and some final tips:

In 2008, a residential 5KW (kilowatt)  system probably cost $8/W installed ($8,000/KW), or $40,000. A 30% federal tax credit could help bring this down to $32K, and with electricity at about 10 cents/kWh, simple payback was roughly 50 years, give or take.

Now we’re looking at installed costs of just over $4/W installed for that same 5KW system, or $20,000 installed. We have a 15% Iowa tax credit now on top of the federal 30%. With higher electricity costs (and likely to continue rising), many if not most Winneshiek County households, farms, and businesses could see simple payback times of near or well under 10 years. Quality panels can easily produce for well over 30 years.

Yes it is still an investment, but in most cases a good one relative to other options, and don’t forget: clean energy is also an investment in a better future. A few thoughts of more things to consider:

  • EFFICIENCY FIRST – it doesn’t make much sense to install an 8KW system for $32,000 (for example) if you could first reduce your electrical usage/demand by investing, say, $5,000, and then only need to build a 5KW system for $20,000.  Contact us for more information.
  • Financing: Solar photovoltaics are a major, though sound,  investment. It is an asset with close to guaranteed return and as such should be eligible for financing on good terms. Decorah Bank and Trust is currently offering energy efficiency/renewable energy loans specifically for such projects.
  • A solar PV array on your building or property is somewhat of a fixed asset – it can be moved but is best left in place for quite some time. This means that if you sell, you’ll want that investment reflected in the valuation of your property. This is growing area of interest and learning within the real estate community, and if you plan to sell in the near future you may want to have some discussions with appraisers, realtors, and others.
  • Currently the only solar PV option for most of us is to pay for and own our system, but we’re working toward changing that. A community solar field could potentially allow us all to buy shares or actual generating capacity, have the generation credited to our utility bill, but also have benefits such as economy of scale, convenience of a common location, transferability of the investment, and more. Another model would allow you to contract with a solar business that could build AND OWN a PV system at your location, so instead of you investing in a major system, you just purchase the power generated the same as you purchase power from a utility. Neither of these options are available through Iowa utilities at the moment but we’re hoping that will change.
  • Shade-Site-Shade: for on-site solar PV, you need a relatively shade-free (especially to the south) place to put it, whether “ground mount” or “roof mount”. You probably know whether you have this, but the Beacon assessors site can provide you with good aerial imagery, as can sites such as Bing and Google Earth. A good solar site assessment and consultation by the Energy District will review all this and much more.
