If you are thinking of participating in your local club’s Field Day festivities or are heading to the campground with your family for a Bravo station, bonus points are available.

One of my favorites is the Alternate Power Field Day bonus.

To quote the ARRL Field Day rules for 2009…

“7.3.8. Alternate Power: 100 bonus points for Field Day groups making a minimum of five QSOs without using power from commercial mains or petroleum driven generator. This means an “alternate” energy source of power, such as solar, wind, methane or water. This includes batteries charged by natural means (not dry cells). The natural power transmitter counts as an additional transmitter. If you do not wish to increase your operating category, you should take one of your other transmitters off the air while the natural power transmitter is in operation. A separate list of natural power QSOs should be submitted with your entry. Available to Classes A, B, E, and F.”

Last year one of our club members brought a fold out solar panel array. Originally he hooked it up to a FM HT. The solar panels powered the HT just fine, but no one was on the air to make contact with.

Then an Elecraft K1 transceiver arrived. Hmmm…

Since the K1 is an HF transceiver one of the other stations (we were 4A last year) would have to cease operation while we operated the solar powered station.

No problem. We went to our CW tent and…

• Disconnected the antenna coax from the main CW transceiver (a Yeasu FT-2000 by the way – nice)
• Connected the antenna coax to the K1
• Flipped the solar panels out along the ground
• Hooked up the power to the K1
• One person operated the key and the K1
• While the person in the CW tent logged the QSOs on the N3FJP Network software
• and made note of these particular QSOs as “Alternate Power” contacts
• Logged five Alternate Power QSOs
• Reversed the process to get the CW Station back the way it was and continue to operate normally
• Done!

Here is our K1 operator, logger (in the tent) and the impressive solar array…

Making Solar Power QSOs during Field Day

This was pretty easy really.

In this case, the low current draw of the Elecraft K1 really helped. We did not need any temporary storage from a battery in parallel with the solar output. It all just worked straight off the solar power source. Nice.

You may desire to try the above and I really do suggest it. It is fun. If your rig needs a bit more power than the K1, consider adding the battery and letting it charge for a bit before making those five QSOs.

I hope to hear all of you on Field Day. Good Luck.

As a demonstration of how solar can work, this is a terrific Field Day activity.

During the solar demonstration, visitors and participants often ask about the viability of using PV Solar Panels as an offset to their electric bill. The motive is obvious… save money.

I have known for some time PV Solar is very expensive and has Return on Investment (ROI) periods of decades. That was some time ago though. I decided to check out the latest solar calculators to see if PV Solar was still a hopeless financial investment.

Before I do I want to emphasize two different payback systems: Financial and Energy. Financial is the real-world desire to save money harvesting free energy from renewable sources. Energy Payback is the measurement of how long it takes for such a system to produce more energy from renewable resources than it took to manufacture.

The Energy Payback of PV Solar cell systems has various opinions. Some say these systems can never generate the energy used to manufacture them while others say they can. The answer appears to be somewhere between one and four years depending on the type of PV Solar material used. That’s not too bad, but needs to be taken into account for those who purchase these systems for philanthropic, energy displacement, purposes.

Moving back to the topic of financial benefits I turned to the Internet to find the latest thoughts on the payback (financial) of PV Solar Systems…

Many PV Solar equipment manufacturers are eager for you to calculate the financial benefits of going Solar Electric. I plugged in the figures from my electric bill in one of the calculators above and came up with an install cost of about $86,000 and an ROI of 25.5 years. Hmmm…

It is true PV Solar systems can have lifetimes of about 30 years. However, there is no excuse for a system to take nearly that long to pay for itself – IF saving money is your goal.

I live in Fauquier County, Virginia and receive a free magazine called Warrenton Lifestyle. There is a regular column called “Ask the Builder” where folks send in questions. In the May 2009 issue a reader named Mary asks and I summarize – “I have heard a lot about solar and wonder if I can supplement my electric energy needs with it.” The column writer responds “…adding solar to your home is a great way to save on every costs…”

No matter how much or little PV Solar you add to your home the payback period appears to be on the order of 20 or more years. It is true this payback period can be shortened if energy prices continue to rise; This is likely to be true. However, as folks who have budgets, we need to be very pragmatic in our choice of investments.

All of us are businesses whether we think we are or not. We have income, expenses, property, liabilities and investments. No business will purchase a piece of equipment with a return on investment longer than three to five years. Why should you?

Think of it another way. PV Solar systems have an impressive lifetime of about 30 years. Great! Why should your PV Solar manufacturer and installer receive all the benefit from the system on your house? That’s right! If the PV Solar installer sells you a system that takes most of its life to generate a benefit (profit) for you, then only he is profiting… at your expense. Why would you do that?

There is a general trend in the industry to price its products with ROI far longer than the common sense limit of 3 to 5 years. I realize there are exceptions to this rule, but we are not purchasing a Boeing 787, a Cruise Ship or a Hydro Electric dam.

Stay away from any Alternative Energy installer that uses any kind of ROI calculations longer than five years. Bogus! There is no reason for you to pay $1/kWh if you can buy it for 13 cents.

Also, do not include any tax credits or other government benefits in your calculations. Just because we all are taxed to benefit your solar installation does not make it a good business decision.

This, of course, does not apply to the following folks:

• The Green Energy Philanthropist (GEP) who is willing to make the investment as a statement of their desire to not use conventional energy sources – All should applaud these folks as they put their money where their mouth is.
• The person who’s home is not on the electric grid for whatever reason.
• The amateur radio operator who just thinks this is cool and, like the GEP, just wants to do it

If you are trying to save money with PV Solar you are well advised to invest your money in a money market fund instead. You will come out ahead after 30 years.

If you agree PV Solar is too expensive to be practical, you should still keep an eye on the industry. If PV Solar becomes just one order of magnitude less expensive to install it will suddenly become practical to install for financial gain.

One last thing to try… Ask your energy provider if they are interested in renting your rooftop for “their” solar panels and related equipment. As reported in Uncle John’s Certified Organic Bathroom Reader, page 39, the payback to the homeowner is no cost electricity. Now that’s an ROI that’s pretty amazing.

Conclusion:

PV Solar is very expensive, but getting cheaper as the technology continues to mature. Eventually it will pay to install your own equipment, however, if you can rent your roof to your utility, your payback is instant.
