So much as been made of the new energy economy and the green revolution that many folks have questions about solar power. Many people would like to install a solar power kit, also called a photovoltaic (PV) system, on their home. But most of them don’t know how much these systems cost and how much they can afford. This article will help you determine if a solar power system is in your budget. We’ll start with the questions you need to ask and answer.

How Much Power Do I Use? The first task is to determine just how much energy you are using. See our related articles on energy audits to reduce energy waste. Next, look at your power bill. You should see your monthly and yearly usage. This information will be helpful in determining just how much solar energy you really need. You should also note how much your power us costing you in dollar per kilowatt-hour ($/kw-hr).

Are there Rebates and Tax Credits? The short answer is ‘YES!’ There are hundreds of programs around the country to encourage people t install solar power systems on their homes. The federal government has a 30% tax credit for solar and wind systems. Contact your local power utility for information on rebates that they offer. In some parts of the country the power utilities are offering to pay for nearly half the system. Add this to the federal incentive and you might have 80% of your system paid for by others.

What Size System Should I Get? This question is hard to answer for you. Most people start by trying to cover a percentage of power that they use with solar. Many people start with 25% to 50% of their total power. With the tools you can find on SolarSphereOnline.com and Findsolar.com, you can determine just how large of a system would be need to generate some or all of your power with renewable energy.

If you assume that an installed system will cost about $10/watt, you can estimate a rough budget for the project. For example, if you start with a 1,000 watt system (which is nice place to start for a lot of homeowners) it would cost about $10 x 1000 = $10,000 for the labor and materials. Remember, there are plenty of incentives out there. So if you had a $2/watt rebate from the utility and took the 30% federal tax credit, your actual system cost would be $10,000 – ($2/watt x 1000watts) – (.30 x $10,000) = $5,000. So you could spend the money you saved on something else for your house or even better get a bigger solar power system!

Can I Do a Little Now and Add More Later? One of the best things about solar and wind energy is that they very expandable. You can put in a few panels now, monitor their performance, and then add on to the system as your needs and budget allows. It is generally better to start out knowing you are going to expand later, so that you can plan your space and equipment usage better.

What’s the Next Step? Its always good to talk to a solar professional to evaluate your home for solar panel suitability. There are numerous sites on the internet that can direct you to local, insured, and experienced PV installers.

fv pv table

If youÂ’ve got Microsoft Excel (or just about any other popular spreadsheet program) running on your computer, you can use its FV function to forecast the future value of your 401(k) or 403(b) account.

The FV function calculates the future value of an investment given its interest rate, the number of payments, the payment, the present value of the investment, and, optionally, the type-of-annuity switch. (More about the type-of-annuity switch a little later.)

The function uses the following syntax:

=FV(rate,nper,pmt,pv,type)

This little pretty complicated, I grant you. But suppose you want to calculate the future value of a 401(k) or 403(b) account that’s already got $10,000 in it and to which you and your employer are contributing $200-a-month. Further suppose that you want to know the account balance—its future value—in 25 years and that you expect to earn 10% annual interest.

To calculate the future value of this account, you enter the following into a worksheet cell:

=FV(10%/12,25*12,-200,-10000,0)

The function returns the value 385936.13—roughly $386,000 dollars.

A handful of things to note: To convert the 10% annual interest to a monthly interest rate, the formula divides the annual interest rate by 12. Similarly, to convert the 25-year term to a term in months, the formula multiplies 25 by 12.

Also, notice that the monthly payment and initial present values show as negative amounts because they represent cash outflows. And the function returns the future value amount as a positive value because it reflects a cash inflow you ultimately receive.

That 0 at the end of the function is the type-of-annuity switch. If you set the type-of-annuity switch to 1, Excel assumes payments occur at the beginning of the period (month in this case), following the annuity due convention. If you set the annuity switch to 0 or you omit the argument, Excel assumes payments occur at the end of the period following the ordinary annuity convention.

Curious about how much money you’ll accumulate in your 401(k) or 403(b) retirement plan? Just use Microsoft Excel to calculate a pretty good estimate says author and CPA Stephen L. Nelson.

transparent photovoltaic windows

transparent photovoltaic windows

Solar company Konarka has developed a transparent solar cell that it hopes will be built onto electricity-generating windows.

The Lowell, Mass.-based company on Tuesday said it has reached an agreement with Arch Aluminum & Glass to use Konarka’s plastic solar cells in building materials, such as ?????? and including windows.

Under its Arch Active Solar Glass development, the company has built prototypes of windows with the solar cells between two panes of glass. The photovoltaic cells can be tinted different colors.

“It is energy-efficient and transparent with superior vertical performance and a subtle red, blue or green aesthetic. With these features, BIPV (building-integrated photovoltaics) will no longer need to be confined to spandrel or overhead applications,” Arch CEO Leon Silverstein said in a statement.

Konarka makes organic solar cells made from flexible plastic. Last fall, it opened a factory in Massachusetts to manufacture the cells which come off assembly lines as spools fitted with wires to carry electricity.

The advantage of these flexible cells is that they can be used for a wide range of applications, such as power-generating military tents, portable chargers for electronics, and sensors.

But these organic photovoltaics aren’t very efficient at converting sunlight to electricity and won’t last as long as a rooftop solar panel, which is typically under warranty for 25 years. Konarka said late last year that it achieved 6 percent efficiency in its labs but that’s not yet available in its products. A high-efficiency silicon solar cell, the most common cell material, can be over 20 percent.

Konarka’s factory is turning out red solar cells but has started making the transparent cells in limited runs for prototypes and development, according to a representative.

Although Konarka has raised over $100 million and has signed a number of partnerships, there are many people who are skeptical that the company can be profitable.

“The real key will be to see if they can make building-integrated products that can stand the weather for 20-plus years,” clean-tech venture capitalist Rob Day from @Ventures told Greentech Media in December last year.

Konarka also faces growing competition in the building-integrated photovoltaics field. Thin-film solar manufacturers, including Heliovot, also make flexible cells (??????????? ????) that can be fitted onto glass or building structures such as awnings but are more efficient. Nanosolar’s cells made from CIGS (copper indium gallium selenide), for example, are in the 9 percent to 10 percent range.
