Solar Panels: PRICE PER PEAK WATT?

We Answered:

Watt peak is the amount of power that a PV module is able to supply when it receives 1000 watts per square meter of solar irradiance. A simpler but not as accurate definition is watt peak is the amount of power that a PV module produces at noontime when the sun is directly overhead and there are no clouds to block it.



found the following online. Not too good in the grammar department tho.

Watt peak is the rating of PV modules. Though the watt in watt peak refers to the watt discussed in the previous section, the term peak makes a lot of difference.

PV modules supplies energy by converting light energy from the sun to electricity. The amount of energy it is able to supply per second is measured by the unit watts. Yes, watts is applicable to PV modules; so why rate it using watt peak. PV modules supply power depending on the amount of sunlight it receives and since the amount of received sunlight varies; the power or the amount of watts supplied varies.

To accomodate the variation in power production, watt peak is used. Watt peak is the amount of power tnat a PV module is able to supply when it receives 1000 watts per square meter of solar irradiance. A simpler but not as accurate definition is watt peak is the amount of power that a PV module produces at noontime when the sun is directly overhead and there are no clouds to block it.

why is the price of solar panels cost efficient?

We Answered:

They are not where I live. Our grid power costs about 10 cents per Kilowatt-hour. The break-even point here is about 13 years (in 13 years I will have saved enough to pay back my investment). This is even with almost 50% subsidies from our tax dollars and electric company rebates which really should be included because it is real money. The problem is the equipment will all probably need to be replaced by then, so there is no real savings to me.

Just go to your electric utility website and you can normally get all kinds of good information on sizing and up front cost, as well as estimated savings over time.

In my state (Arizona where the sun shines almost every day), a fairly good system for a 2000 sq ft house has a total cost of about $30,000-$40,000 installed. With tax subsidies and rebates, I pay out initially only about $16,000-$20,000. The system will pay me back all my money in 11-13 years not considering any equipment replacement or maintenance cost.

If you live in any areas where you have a lot of cloudy days, I can't imagine even considering a solar system unless you just have a lot of extra money and want to do it to be green.

Here's a good site that has a good selection, with prices listed, for everything you'll need to build your own solar energy system.

What is a reasonable price for enough solar panels to power a large amount of condos and other buildings?

We Answered:

i would look at this in a diverse approch.
1. being that it is florida, i would start with using PV on the houses in combination with a couple of small peak mounted wind turbines (sources oynot.com, solardyne.com, sunwize.com and on and on).
2. condo's are different. they usually have flat roofs so the turbines would be out of the question and so would PV. Instead i would use hard mount solar panals, and try to be energy efficent in other areas of the construction.
3. the pool is an easy one. your in florida, unless you want to cool it in the summer, and heat it in the winter, then just run the water through a condenser that is in a solar water heater loop. and the same answers apply to the rest.
But the best ans is think about it before you build, build with the surroundings, and plan for it by being construction wise.
