Back to the real issue.
Can solar panels be made that are 45% efficient AND still not heat up and crack to keep a 25 year warranty like todays great panels?
Can their cost be at $1-2 a watt like many of todays panels ?
We already have great panels that are very reliable, we need more efficient homes and appliances like the LED lights and PC displays I use. My home has 4 Kw, less than half my roof area and makes more that I use to run my home and 100% electric LEAF vehicle.
Energy storage is also an issue sine fossil fuel and nuclear and even hydro make energy at night Off Peak we could store and use days. V2G-101.com can provide that storage at very low cost.
Arizona has First Solar and Sunteck, along with the most sun of anyplace on earth. We will prosper even against subsidied fossil fuel and Chinese PV.
Now if we can just get to keep our SRECs and get Feed In Tarrif since solar is clean and during the Peak Time of day.
CPV has always been great. The new Sunpower C7 system sounds like the perfect balance of not too little or too much. This should make the output last for a long time and be reliable. Sunpower has already been a leader in top efficiency in PV for many years.
I would think AZ, NM and California would be lowest cost since they have the most Sun to make the most per KW installed. The Production should be part of the data.
Here in AZ the cost installed is about $4-5 a watt today. Then we have Federal incentives like all state plus a state incentive of $1K and local utiltiy incentives of about $1.20 a watt. We also have Net-Metering with 1 year roll over.
Other states have Feed In Tarrifs and REC or SREC credits. There is a lot to account for.
Then the type of local power and all of it's incentives like COAL, NG Hydro and Nuclear. They are hard to figure and now you have new pollution carbon taxes and mercury reduction limits coming out. I guess until they are set you can't show them as hard costs but it sure helps to know what they are and how big they are even after 30 years or more of being on the books.
Home power has a PV vs SUV chart that shows how much you save comparing the 2. homepower.com/article/?file=HP90_pg46_Smithson
FYI just in case
PV is Photo Voltaic electric panels, made in the USA of course
EV is electric vehicle, also made in the USA
SUV is Sport Utiltiy Vehicle
I also like to compare PV vs a Swimming Pool. The PV makes money while the Swimming Pools uses water, electric for pumps and chemicals.
With An EV and PV I call it Feed In Transportation, where about $1 in an EV of electricity replace 2 gallons of gas $6.60 today at 25 mpg. Add in the Environmental factors and it's priceless.
If people really compare investments Solar PV is a big winner.
as OIL, gas,diesel prices rise so will stock in Tesla. When their new Model S Sedan is released in June and gas is $5 a gallon I want to own as much of their stock as I can.
The Energy Storage issue is big. The US Imports 50% of the OIL burned in 20% or less efficient vehicles every day. Power plants have excess energy Off Peak and can't ramp down or up so it's wasted. Solar and Wind could be stored for more use in the GRID.
awesome pictures. This is a great perspective on how great Solar PV is all around the entire world. Nice job, very inspiring.
Tibet: World's Highest PV System
dogworld, when you mention we all pay subsidies so solar isn't really cost effective yet ,you forget to add the subsidies we have paid to fossil fuels and nuclear for over 30 years. If you remove all subsidies and include real world external costs like pollution and water use SOLAR IS LOWER THAN GRID electric today.
Solar is also distributed so it's made and used right where it's needed and send clean power over teh GRID to help it's closest neighbors. Then reduced transmission and transformer losses. It also is highest during the Peak Time of day hours and smoothly shuts down at night when we have excess in the GRID since use is very low at night.
Not having a pool is even more efficient.
Counting the value of Solar during the Peak Time Of Day with no pollution or water use shows it's priceless.
With Millions of Electric Vehicles all V2G GRID conneted helping regulate power and povide back up for the little off peak use it's the complete answer. In fact all of our food comes from solar, photosynthisis.
It would be nice to list these by country. The biggest in the world is First Solar FSLR in Tempe Arizona with manufacturing in a few countries. It is a big world and global economy but I like to buy USA made items.
Yes, any tarrif reduction should be done evenly and smoothly ,not a drastic drop.
We should also start reducing the subsidies that have existed and increased for over 30 years on COAL ,Nuclear and Natural Gas. Then we will get to a real level playing field and discover Renewables are already less cost than fossil fuels.
The Energy Storage also needs to be built up in the millions of new advanced battery vehicles and even 2nd use EV batteries at stationary locations. These make Renewables 24/7 dispatchable. Other exisiting clean soruces like hydro also help Off Peak with steady output 24/7
It a whole new world with Renewable Energy and clean air.
