Silicon Valley is hot again, and it’s a good thing for SunPower Corporation, a company which just released the most efficient solar panels to date. Based on the new Gen 2 Solar Cells, the SPR-315 solar panel will get a whopping 22% photovoltaic (PV) efficiency – over 10% more than the standard 7-12%. What does that extra 10% get you? Well according to SunPower, it means 50 percent more power per square foot of roof area. That means you can get just as much power using 1/3 as many panels or 50% more power with the same amount of panels. Unfortunately SunPower hasn’t released a price on the panels, but we’ll find out when they hit the market next spring.
“SunPower contines to lead the solar industry with its innovative technology and smart design,” said Peter Ashenbrenner, vice president of marketing and sales. “Our new SPR-315 solar panel breaks the 300 watt power barrier while offering even high efficiency than SunPower’s previous industry leading products.”
The SPR-315 will be on display through the end of the week at the Solar Power 2006 Conference and Expo in San Jose, California.
I believe that, Solar power systems are one of the cleanest and most viable ways to generate clean, renewable energy
DBK is NOTsetting up a solar farm in Lassen County. They are however, taking your money. Send them your money. Send them ALL your money. Hurry up!
DBK solar has effeicient panels also, they talked about setting up a sun farm here in Lassen County. They claim up to 3000 watts on ONE panel. Also, as far as dgrading, I have one neighbor who has 3 panels that are utterly shattered on the glass part and they still produce almost full power. They are at least 20 years old. Since they don't move around, they just sit there and transform sun energy.
As a Sunpower dealer in New Orleans I am certainly aware of the tax credits available here.I certainly do wish that Mary Hebert will read this and give a call. When it comes to installing solar panels in New Orleans and the Gulf South the current incentives are helping to build the Solar industry and create jobs. Mary, you can find us at http://southcoastsolar.com
We want to build and use panels in the Bisbee area of Az. People there have had breakage to panels from the high winds in the area. Do you have any suggestions please. Jean
trying to weed my way through the overgrown mass of information and misinformation in order to build an energy efficient home...is there a site that can help me with this...I've read too much and the constant changing of tech and laws is overwhelming.. I lost my home due to arson 3 mths. before katrina so like many of southeastern US citizens we now reside in 35 foot travel trailer...I'm thankful I have a roof over my head but our electricity is costing us over $170.00 a month...the company which we are supplied through is ENTERGY.. The company attempted bankruptcy after Katrina but they failed. Investors have no reason to put up the cash in order rebuild the infra-structure destroyed by the hurricane when they know Entergy can get it from their customers who have no other options. We use no air conditioning ( slightly uncomfortable) two refrigerators, a washer, a dryer on rainy days, your clothes are baked dry in about 20 min here outside on sunny days..and a tv set...oh yeah, and waterwell...so when you look at our bill our initial khr usage is small but we are paying for not only the electricity used but also the fuel used to generate, the wires.and posts for transport and even a service charge for reading out meter . which they don't do since we receive our bills a month ahead of time on esitmate of prior usage. I am concerned about our environment so have been considering solar for a long time but now I am encouraged by recent developments in LA law encouraging the use of solar...I need efficient, resilient, and cost effective panels..I'm weary of the hype and gouging directed to the fashionably evrisound clique..I just want to be able to sustain my self and my home with minimal polluting and still be able to afford to build the house to which the solar panels will be attached..any info is greatly appreciated... thanks for reading my novelette of tribulation you deserve a gold star for sheer dogged determination...I hope you win the lottery
Looking Into building a house in 2008 in Floida w/solar power- specs, pricing and life span and durability are all important conciderations.
hi, i am a 14 year old and i am raising money for a solar panel fund for our school, I'm not really sure what solar panel i should buy and how many watts i can get, i am donating 400.00 to the fund, there will be about 2220.00 in the fund then, what solar panel could i get for that and how many watts, please post on my blog for and iformation
Efficiency could be meaningless if the panel has a poor negative tolerance rating ! They may offer a high efficiency module but what about their module's negative tolerance rating ? Most solar modules on the market offer negative 5 percent or better ! Their 200 and 215 watt modules only offer an 8 percent negative tolerance rating (Lower is better) So when you bought one of their 215 watt solar panels, they would only guaranty that you would get 197.8 watts right out of the box ! It says so right on their panel's specification sheet, look for the panel's peak power tolerance. So if they will be offering the same negative tolerance rating on their new 315 watt solar panels, that would mean that you would be paying for 315 watts but they'll only guaranty that you'll get 289.8 watts ! So much for efficiency !
Price please and what kind of wind resistance? I live in New Orleans
Two questions: 1. Does the panel degrade, losing efficiency? If so what is its projected life span at say plus 15% efficiency? 2. How reistant is the panel to storm damage? In post-Katrina New Orleans it is clear that buildings and their systems must be both self sufficient and storm-proof. Please send your full specifications as soon as possible.
sunpower is public spwr...... invest wisely!
Definitely interested in the details, i.e. availbility, price, etc
For potential cost effectiveness, what do people think of the possibilities of Sliver Technology? See www.originenergy.com.au
Very exciting news. Aside from the usual considerations of reliability and durability, price will be extremely important. If you charge exhorbitant prices for this advancement, you can count on losing a lot of potential customers. Most people I know will find more space for less efficient panels if your cost is significantly higher.
20% efficiency is not 10% more efficient, it's roughly 100% *more* efficient. You will want to fix that in your write-up. This is great news, although I wonder about the cost difference, as these don't yet have the volume production as the "version 1" PV panels.
