San Diego leads L.A., San Francisco in rooftop solar power
If you're searching for a bright spot in a dismal economic climate, look no farther than your roof. The downturn is helping to make solar panels more affordable.
Manufacturers are cutting prices to move inventory. Uncle Sam is helping too. As part of the economic stimulus package, the federal government this year boosted tax credits to homeowners who switch to solar power. Together with state incentives, those subsidies could slash the cost of some systems in California by 50% or more. Some homeowners are banding together into buying groups for even bigger savings.
If you don't have a lot of extra cash lying around, innovative financing can help you spread your payments out as long as 20 years. Or you can take advantage of leasing deals to get panels on your home for little or no money down.
June was a record month for state rebate applications by California homeowners. Some of them are opting for the steady returns that come from lowering their energy bills rather than betting on volatile stocks or real estate.
So shake off the recession gloom and let the sun shine in. Here's how to go solar without going broke.
The basics
A well-designed solar-power system can reduce your annual electricity expense to zero over the 25- to 30-year life of the panels. Spending $20,000 or more on a system today amounts to pre-paying your power bill for the next three decades.
Is that a smart decision?
If your aim is to help the planet, the answer is a resounding yes.
If you're looking to save money, it depends.
Not all homes are good candidates. Generally, the higher your current electric bill and the sunnier your roof, the more solar makes sense. Still, payback can easily take a decade or more. You'll need to crunch some numbers.
Reputable solar installers will be glad to help you figure the payback period, lifetime savings and rate of return, free of charge. If you want a ballpark estimate without the sales pressure, check out the calculators section on the state's Go Solar California website. A particularly good one is the state's own Clean Power Estimator.
Once you've made the decision to go solar, your final cost will depend on four main factors.
• System size -- Solar modules typically are priced by the DC or direct current watt. A typical-size system in Southern California ranges between 4 kilowatts (4,000 watts) and 5 kilowatts (5,000 watts).
• Panel prices -- They're falling. That's a good thing.
• California rebate -- The state subsidy is declining. That's not such a good thing.
• Federal Investment Tax Credit -- A once-modest incentive just turned into a really big deal this year.
Let's take a closer look at those last three.
A buyer's market
Demand for solar-power systems in much of the world has slowed along with the global economy. Meanwhile, solar-cell factories planned when the market was booming are coming on line. The result: too many panels and too few buyers. To move them, companies are cutting module prices.
In the U.S., wholesale prices for top-quality modules made of crystalline silicon have fallen by 50% over the last year to around $2.40 a watt, according to Nathaniel Bullard, solar analyst with New Energy Finance in Alexandria, Va.
"It's really a precipitous drop," Bullard said. "The mood in the industry is grim."
Panels typically account for less than half of the final "retail" price most consumers pay for solar. Unless you're a do-it-yourselfer, you'll need to hire a professional installer whose add-ons will include labor, permits, taxes and an inverter to convert the direct current electricity generated by the solar array into alternating current suitable for appliances.
Retail prices haven't fallen in lock step with panels, but there's no question that they're coming down fast. Some residential systems that were retailing for $9 a watt to $10 a watt installed before the recession can now be had for about $7.50 a watt. Homeowners who join together to buy in volume are snagging complete systems for a little more than $6 a watt. Big commercial buyers are paying even less.
And that's before factoring in government subsidies.
"Jobs are very competitive, and that's translating into lower prices," said Ron Kenedi, vice president of Sharp Solar Energy Solutions Group, the U.S. solar arm of Sharp Corp. "This is the perfect time to buy solar."
If that sounds like sales hype, here's something to consider: Analysts are predicting further declines in panel prices, so waiting could save you some money.
Or it could end up costing you a bundle.
That's because another major incentive -- the California subsidy -- becomes less valuable the longer you wait.
Great state rebate
The California Solar Initiative provides rebates to owners who install solar panels on existing homes. The 10-year, $3-billion program, which launched in 2007, is funded by the state's utility ratepayers.
These rebates are based on a system's size, performance -- and timing. Californians who purchase sooner, rather than later, are eligible for the biggest subsidies. That's because the rebates are programmed to drop every time the state reaches a certain target of megawatts installed.
For customers of the state's three large investor-owned utilities, the rebates started at $2.50 a watt and will shrink to 20 cents a watt by the time the program expires at the end of 2016. That's a difference of $11,500 on a 5-kilowatt system over the life of the offer.
At present, rebates for customers living in those service territories are as follows: Pacific Gas and Electric -- $1.55 a watt; Southern California Edison -- $1.90 a watt; and San Diego Gas and Electric -- $1.55. To keep tabs on how close all those rebates are to dropping to the next level, check out the Statewide Trigger Point Tracker at www.csi-trigger.com.
Your final rebate will be less than those benchmark figures because the state will apply a discount to account for your roof's shading, the efficiency of your panels, the conversion from DC to AC and some other factors. So figure on getting about 86% of the benchmark.
California's municipal utilities have their own solar rebate programs. The Los Angeles Department of Water and Power, for example, calculates how much power your system would produce over 20 years, then pays an upfront subsidy -- currently 13 cents per kilowatt-hour -- based on those estimates. The DWP website has a calculator known as PVWatts to help you estimate your rebate. (Warning: It's not very user-friendly.)
Check out your utility's website for more information.
Reputable solar firms will handle all the paperwork and give you the California rebate immediately, saving you the wait and hassle. Make certain the firm you choose is registered with the state by checking the California Energy Commission database.
Tap your uncle
The second big solar incentive comes from Uncle Sam in the form of an investment tax credit.
Starting this year, homeowners who purchase solar panels can qualify for a federal tax credit equal to 30% of the cost of their systems after the state rebate has been deducted. The credit is a dollar-for-dollar reduction in the amount of federal income taxes owed.
Here's how the math would work for a resident living in Southern California Edison territory who bought a 5-kilowatt system retailing for $7.50 a watt with an 86% conversion rate for the state rebate.
• System price: $37,500 ($7.50 x 5,000 watts)
• State rebate: $8,170 ($1.90 x .86 x 5,000)
• Post-rebate price: $29,330 ($37,500 - $8,170)
• Federal ITC: $8,799 ($29,330 x 30%)
• Net system price: $20,531 ($29,330 - $8,799)
Lease it
Although government subsidies can reduce the cost of solar substantially -- by nearly half in the case above -- most homeowners don't have a bundle of cash to invest in panels. And falling home values have made it tougher to get a home equity line of credit.
That's why some solar firms have begun offering residential leases and so-called power purchase agreements, or PPAs. These arrangements are already popular with big commercial power users, including Wal-Mart Stores Inc., that want to go green without tying up a lot of their own capital.
Instead of purchasing their own solar equipment, consumers let a solar-power provider install its panels on top of their homes. Homeowners buy the clean energy generated from these arrays, paying a monthly fee to the solar firm much in the way they currently buy power from their utilities.
Upfront costs to the homeowner are minimal, from zero to a few thousand dollars. There's no maintenance either; that's the solar company's responsibility. Contracts are lengthy, typically 15 to 20 years. But they can be transferred to a new owner if the home is sold.
Many customers cut their monthly power bills immediately by at least 10% to 15%. But the biggest savings come in the later years. That's because, depending on the deal you cut, you can lock in a fixed rate or get a contract with a predictable escalator that's well below electricity rate hikes being projected for conventional utilities.
Ned Araujo of Upland turned to SunRun, a San Francisco company that offers residential power purchase agreements. The environmental engineer paid $8,000 upfront to lock in a rate of 13 cents a kilowatt-hour. That's slightly above the cheapest rate available currently from Southern California Edison. But it's less than half the utility's priciest peak rates, and it's guaranteed not to budge for 18 years.
Araujo said he didn't want the headache of maintaining solar panels -- especially in a seismic area.
"Anything that happens, it's their responsibility," he said of SunRun.
Similar arrangements are available from SolarCity, a company based in Foster City, Calif., whose popular leasing program has turned it into the state's leading installer.
The company is making a big push in Los Angeles, where it recently reached an agreement with the city that allows LADWP customers to participate in such lease arrangements. Homeowners with an electric bill as low as $100 or even less can still save money by going solar, said SolarCity spokesman Jonathan Bass.
The company has a nifty calculator on its website where you can plug in the numbers.
Power to the people
In the last few years, companies, including SolarCity, have courted business by offering volume discounts to groups of homeowners who agree to adopt the technology at the same time.
The so-called community solar movement is gaining traction nationwide, thanks in part to a Bay Area company called One Block Off the Grid, or 1BOG for short. Its business is organizing homeowners into groups of 100 or more and using that bargaining clout to get the best deals from solar installers.
Here's how it works: If you're interested in solar, just go to the website and sign up. 1BOG is running campaigns in metropolitan Los Angeles (including Orange County and parts of the Inland Empire), the Bay Area, San Diego, Sacramento and Sonoma County.
There's no cost or obligation. But the more homeowners 1BOG can get to take the plunge, the more leverage they have with installers, who compete to win the contract. 1BOG makes its money by charging the winning bidder a fee.
1BOG offers educational seminars, provides a leasing option and does all the negotiating with solar companies, saving homeowners a lot of hassle.
Retirees Dorothy and Walter Harris of Ladera Heights were interested in purchasing panels but were dismayed by the steep learning curve. After tuning in to a 1BOG Web seminar, the couple knew they had found their company.
"They presented things clearly . . . and made the whole process easy," Dorothy Harris said.
The savings can be enormous. Los Angeles 1BOG members can now get solar for $6.05 a watt installed. That would reduce the net cost of that 5-kilowatt system in Southern California Edison territory mentioned above by an additional $5,075.
The drawback is that you don't get to pick what brand of panel goes on your roof or the company that does the installing. You also might have to wait several months to get your system, depending on how many people are ahead of you in line.
Put it on my tax bill
State legislation known as AB 811 approved last year grants most California cities and counties the ability to offer low-interest solar loans to residents, who then repay those loans through assessments that appear on their property tax bills.
The idea is to make solar more affordable by allowing California residents to spread their payments over 20 years. If the house is sold, the annual assessments become the responsibility of the new owner. That's appealing to homeowners who aren't sure how long they'll stay put.
So far, Berkeley, Palm Desert and Sonoma County have set up programs. San Diego is planning to launch one this fall. A number of cities are in the exploratory phase.
The cost to homeowners and businesses depends on the interest rate provided by the municipality. Palm Desert, for example, offers a 7% fixed rate. So financing a $30,000 system over 20 years would raise a homeowner's property tax bill by a little more than $3,000 a year.
Want your city to participate? Tell your mayor or council representative you want an AB 811 program in your town.

Passive solar home?
There are many affordable options to convert your home into a solar home and solar energy technologies can supply for several different uses in your home. Passive solar design can provide heating, cooling and natural light for your home. Solar electricity options are available to power home appliances and solar water heating can provide hot water options for laundry and general household water use (showers, cooking, cleaning). When planning a solar home it is important to consider which energy options are most efficient, and cost effective for your situation.
A passive solar home utilizes home design to provide heating, cooling and natural light without the use of any special equipment. A passive solar home basically uses the environment to accomplish great reductions in energy use. Useing construction materials and design to utilize the sun’s heat during winter months and block the sun’s heat during summer months. There are several passive solar techniques you can use in a solar home, direct gain, radiant heat from sunlight passing directly into a living space and being absorbed by furniture, flooring etc and usually achieved with south facing window installations, indirect gain, involving an attached Trombe wall that collects heat and distributes it throughout the home by the use of fans, thermal mass, which are materials that naturally collect and store heat such as brick or stone, and passive cooling, which generally includes overhangs for south-facing windows to block the sun during summer months for cooling the solar home.
Another feature often found in a solar home is the use of solar electricity. Solar electricity is generated when photovoltaic cells are used to absorb sunlight and convert it into usable electricity. The energy produced by solar panels must be converted to DC (household power) through the use of an inverter. Solar electricity can be used to supplement metered electric already being received by a solar home or with the use of a battery storage bank, can be used as the only electric source for the home. If the later is going to be used, it is suggested that owners of the solar home have a generator available for backup power.
Solar water heating is one of the most common uses of solar energy in a solar home. There are two kinds of solar water heating available for solar home use. The first is a closed loop system, which can be used in areas that are not prone to freezing. These systems use water filled tubes that are heated directly by the sun. A closed loop system uses an anti-freeze type liquid to collect heat from the sun and then the heated liquid is used to heat household water via a heat exchanger.
Regardless of which steps you take toward converting to a solar home, energy efficiency is the most important attribute to a successful solar home operation. Efficiency minimizes the need for heating, cooling and electricity. Using higher insulation levels, more energy efficient windows, appliance and lighting than used in traditional construction, you will already be saving yourself a lot of money and energy. However these changes may not be an option when converting an existing home into a solar home, so make any changes possible to your home energy efficiency and adapt other solar practices to convert your existing home into a solar home.

Why Wind energy?
Renewable wind energy is the fastest growing source of power of any renewable energy sources and technologies. With wind energy, the flow of air turns wind turbines to create electricity. As the speed of the wind turning the turbines increases the amount of power the turbine produces increases as well. In areas where winds are strong, renewable wind energy is a smart choice for providing power to homes and businesses.
Even if you don’t live in a windy area, you can still supplement your current electricity supply by utilizing renewable wind energy. The best part is by using do-it-yourself guides; even the least skilled handymen can build their own windmills and start using renewable wind energy to lower their electric bills each month. However, if you do live in a particularly windy area you can feasibly generate an abundance of electricity from renewable wind energy systems.
It is also conceivable to build several wind turbines to power your renewable wind energy system. Most of us have seen the pictures of the wind farms being built to supplement power to whole cities. This is a little much for a homestead, but even small dwellings can benefit from multiple smaller wind turbines. In many states, it is possible to sell the excess electricity you generate from your renewable wind energy system back to the utilities companies.
The very best part of integrating a renewable wind energy system into your home or business is the environmental impact. Renewable wind energy produces little to no pollution, no harmful greenhouse gases and no methane or carbon dioxide-which contribute to global warming. And of course the savings those homeowners can realize after their initial investment in renewable wind energy.
It is definitely worthwhile to learn more about renewable wind energy. By building your own wind turbines you can add needed dollars to your pocket and help the environment at the same time. Renewable wind energy. Free power from the wind. Sounds beautiful, don't you think?

Learning about Wind Turbines
How would you react if your neighbor told you she was going to build wind turbines? Pretty impressed? The truth is that it is not difficult to build wind turbines and many homeowners are taking the challenge to build their own wind turbines as a cost-effective means to utilizing renewable energies. It isn’t exactly snap-your-fingers easy to build wind turbines either, but with the proper plans and a motivated builder you can be building wind turbines in no time.
It is definitely your best bet, before setting out to build wind turbines, to purchase an instruction manual or guide to follow. Remember that you get what you pay for when it comes to instructions. Make sure you find a manual that is easy to read with detailed instructions. There are also many online resources and forums to help guide you through your wind turbine building process.
To familiarize yourself with the basics, before you get started on your project to build wind turbines, there are four basic components to wind turbines. To build wind turbines you must be familiar with the towers, the batteries, the turbines and the tail and propeller assembly. The tools generally required to build wind turbines are simple as well, you will need wrenches, a saw and a drill. There may also be a need for additional tools depending on how many of the wind turbines you will be building yourself.
One part that you will probably be ordering when you decide to build wind turbines is the motor as they are nearly impossible for do it yourselfers to make. The motors on wind turbines do require regular maintenance and oiling for continued efficiency, but this is a small price to pay for the excellent energy these systems provide. In addition to the motor, you are definitely going to need a good-sized workspace. Depending on your target energy output, your propellers or blades could get up to 8 feet in diameter (4 ft blades).
It takes a little work to build wind turbines, but there is really nothing overly complicated about the process and generally the process can be fairly inexpensive once you are operational and your electric bills are dropping each month. Building wind turbines is also a fast growing occupation worldwide as technicians are tough to find. So learn how to build wind turbines for yourself and take advantage of the opportunities that free electricity and know how can provide.

How I Will Make My Own Electricty
Hello Everyone:
Mike here again. I just wanted to share How I plan to use this information in the E-book that is for sale at my partners site. I am going to relocate to the Philippines and get a place and then put up solar panels, about three i think, as well as a wind generator. That way all i have to pay for is food and rent as well as water. I will write articles to promote products that i believe in as well as a couple of my own products/services. I will live very very well there on 1000 dollars a month in a smaller city. I will sell local made crafts on ebay, and rent out gaming systems to people for small amounts an hour. Any one stream of income will be enough to pay for my simple life. I'm just tired of the direction things are going here in america. Ive been outside of the country before when in the army and again on vacation 2 years ago. I really believe in the concept of helping people become energy independant, worldwide.
I also want to produce enough money to be able to help those that are poor and have so very little to live on. A friend of mine has a yahoo group that helps publicize a situation like that http://groups.yahoo.com/group/onelife_changed/ He has sponsored a school class. His sister in law is the teacher. Its a 4th/5th grade class. How old are they at that grade? 10? 11? They had never owned tooth brushes before!! As you can maybe figure it doesnt take much to help kids like that. No matter who you are you could probly afford to make a huge difference. So this is what im doing here... Trying to make money online so i can be in ministry full time and only market part time.
peace
Mike

How to make your own electricity.
Hello
My name is Mike Jansen and I want to tell you about Making your own electricity. I have found a great site that you can buy plans on how to make your own solar panel or if you choose you can make your own wind generator, or both. In these economic times wouldn't you like to tell the electric company to do rude things to themselves? These plans are something you can use to make a electrical generation panel or a wind generator in a weekend. Its very inexpensive and can be done for 200 dollars or less. The plans are very clear so that even a non techie can do it. If you are a total non hands on type of person usually your local hardware can suggest a handyman that you could pay to do it. The idea is very inexpensive go here to check it out.
You could run everything in a simple house with 3 solar panels and a wind generator. The good news is that if you produce more electricity than you use the Electric company will pay you for the electricity you send back into the grid. So instead of you sending them money every month, you could get the same old envelope from them, but it would have a check instead of a bill in it! In the united states of America (sic) they by law have to pay you for your extra unused generated electricity! If money is tight as it is for us all, just do as i have done, get one panel going then with the money you save from the electricity you are not paying for use that money to make another panel. Do that till you are no longer paying for electricity at all!
So even if energy prices continue to go up after you are off the grid you will have no worries. Let me tell you its a great feeling.
Feel free to comment or ask questions :).
