You've likely heard this before: "Now is a great time to go solar." While that statement has been true before, it has never been more true than it is today. But wait a minute! Haven't the utilities eliminated most of their incentives?

Yes, but even with the loss of utility rebates, solar photovoltaic electric systems are less expensive now than ever before. Also, installation costs are less, without incentives, than they were just a few years ago.

People interested in solar systems for their homes or businesses should make a few calls. They will find that complete systems can be designed, permitted and installed for a fraction of what one might expect.

If the upfront costs are still daunting for those on tight budgets, there are lease and financing options that can put a solar system on a home for less than the typical monthly electricity bill.

There is some controversy about net metering. This is the program where solar producers trade solar electricity for utility-provided electricity. When solar electric customers provide extra electricity from their solar panels to the grid, those kilowatt hours are banked in their utility account. Then at night when the customers need utility-provided electricity, they first draw on the banked solar electricity credits. After those credits are used up, the customer pays the utility as usual for the electricity used.

The interesting thing about this deal with the utilities is that solar customers provide electricity to the grid during "peak demand" hours when the sun is strongest and the customer demand can be highest. It's also when electricity is more expensive. Utilities typically charge several times more for electricity used during peak hours. However, with net metering, they provide very cheap nighttime electricity to their solar customers in exchange for the very expensive peak demand electricity they receive. It's not really a net metering trade. It really works out to the advantage of the utilities.

However, the utilities complain that they have grid maintenance costs to meet. Every utility customer, including those with solar panels, pay something each month to cover grid maintenance. In addition, the profit utilities make on net metering can offset any loses they experience from solar customers using less electricity. So, any reasonable consideration of the net metering issue should be decided in favor of the expansion of solar resources in this sunny state.

That's the financial argument for going solar. It's also the right thing to do for a couple of important reasons. The first is obvious: solar customers reduce the electricity produced by burning polluting fossil fuels. The less utilities depend on fossil fuels the better it is for human health and the natural environment.

Another reason to go solar is less obvious: it helps conserve water. The average power plant in the USA uses 2 gallons of water to generate 1 kilowatt hour of electricity. So, a home with a solar system that generates an average of 10 kilowatt hours of electricity a day will help conserve 20 gallons of water a day. That is more than 7 thousand gallons of water a year.

If all the homes in Yavapai County had small solar systems generating just 10 kilowatt hours of electricity a day, they would save 2.2 million gallons of water a day. That's more than 800 million gallons of water a year. So what are we waiting for?

There are excellent solar companies right here in the Verde Valley. Several are part of the One for the Verde project. They not only help you save energy, save money and save water, they help us preserve our water resources and the natural environment. Visit OnefortheVerde.org to learn more about it, and to find a great deal on going solar.

Most folks I've talked to have only installed what I would call a `half-system'. Yes, their solar panels make electricity when the sun shines to power their house, but at night, they still rely on APS to power their lights, etc.

A complete solar system includes a bank of batteries. Your panels charge the batteries all day (while powering your house), and at night you draw power back from your batteries to run your house. Of course, the complete system is much more expensive than the half-system.

With a complete system, you unhook from APS altogether. No buyback negotiations, your power is all yours. No smart meter, either. You are totally "off the grid". You don't pay APS anything. Everything it would have cost you for APS' providing you electricity for years and years is credited back against what it cost you for your complete system. In fact, I have one friend who wired his whole house for 12 volts (there are all sorts of household appliances, etc. that run on 12 volts) and has been off the grid for years.

OK, sure, there could be several cloudy days in a row. But here in Arizona that is a slim chance. If it came to that, all you need is a simple backup generator to cover your needs until the sun shines again.

If I were building a house from scratch, this is the way I would go.

Mark my words, eventually the will just take it from you with no buy back.

America is now a fascist country.

The goal of a properly sized residential solar array is to cancel out electricity use over a 20 year period.

Depending on the cost of electricity (which may rise), the system should pay for itself in 10 - 15 years.

Call 3 local solar installers and ask for a written price quotation including :

- 5 killowatt, grid tied system
- 5 kw inverter
- System installation
- design, permits, tax credit filing

Your system may be larger or smaller, but this will help focus on the best local company to determine total cost.

Lease agreements (20 year), are available for those who want to avoid the cost of ownership.

My buy back rate was 6 cents, now( two years later)it is 2.8 cents. I guess they can change the rate whenever they want.
