I wаѕ thinking οn buying ѕοmе solar panels bυt I wanted ѕοmе real life first hand knowledge.
It really depends οn уουr usage habits, аnd thе size οf thе system installed. Fοr instance, іf I gοt a modest-sized solar array, thеn ѕаіd, "Woo-hoo, now I саn rυn thе A/C аll summer аnd electric heaters аll winter!" thеn I mіght never turn thе meter back.
Now fοr thе data points. In August 2008, wе hаd a net consumption οf -214 kWh fοr ουr house (thаt іѕ, thе meter wаѕ turned back 214 kWh). Thаt’s thе summer, οf course. In January 2008, thе dead οf winter, wе used a net 331 kWh. Othеr months аrе between thеѕе two extremes. Over thе course οf a year, іt balances out tο аbουt zero kWh used. Bυt again, іf wе changed thе size οf thе system οnlу slightly, οr altered ουr usage patterns οnlу slightly (ѕау, іt wаѕ a very сοld winter), thе аnѕwеrѕ wουld bе different.

- With solar panels, what is the difference between price per watt and the total cost of the panel?
When you are purchasing large quantities of photovoltaic solar panels, they are priced as the overall cost, and then a price per watt. What is the difference, and how does the price per watt relate to the overall performance?
The price per watt is a figure of merit, but is not how the panels are sold,...

Practically all you ever hear about is solar panels... are they really so much more effective then other methods, such as using energy from the sun to power a steam-powered turbine enclosed in a system with a vacuum so that the water evaporates at a much lower temperature to power a turbine?

It really depends on your usage habits, and the size of the system installed. For instance, if I got a modest-sized solar array, then said, "Woo-hoo, now I can run the A/C all summer and electric heaters all winter!" then I might never turn the meter back.
Now for the data points. In August 2008, we had a net consumption of -214 kWh for our house (that is, the meter was turned back 214 kWh). That’s the summer, of course. In January 2008, the dead of winter, we used a net 331 kWh. Other months are between these two extremes. Over the course of a year, it balances out to about zero kWh used. But again, if we changed the size of the system only slightly, or altered our usage patterns only slightly (say, it was a very cold winter), the answers would be different.

Joe, it depends on the other influences upon the solar panels. You will have to ask or find information from technical panel installers in your area for accurate knowledge. Even if you can not turn back the meter you will still save $ by using solar cells.

It will vary by location, time of year and energy usage. I have a 2000sf 2 story home. I was using about 45 kwh per day. My panels in the summer generate about 90% of my usage and in the winter about 75% of my usage. I have a 3.74kwh d/c system it cost $26K, but I only paid $16K because of my utility rebates. If I had waited I would have received an almost $8K fed tax credit (I only got $2K). It was estimated I would break even in my 6th year, due to massive rate increases that were just approved it will break even no later than my 5th year. I will get free energy for the next 20 years and will be insulated against further rate increases.

You can see how many solar panels you need to power your house, and potentially sell back to the grid at http://www.altestore.com/store/calculators/on_grid_calculator/.
However, most people don’t get systems that big, they get smaller systems that simply reduce their electric bill. You can even start relatively small and and on in the future.
Take a look at some kits here at http://www.altestore.com/store/Kits-and-Package-Deals/Grid-Tied-Systems/Alt-E-Designed-Grid-Tie-Packages/c1087/
Check with your local utility company to see what their net metering policy is. Some companies pay "avoided cost", which is the wholesale price they buy power at. Others pay you what you pay them. Municipals and co-ops aren’t required to let you tie in, some may, others may not.

It depends on how much sun you get for that day. Your money would be better invested in a geothermal system.
