  1. I think every roof that gets good sun. Should have as many panels on it it can possibly get up there… And grid tied or not. Making power for the grid. And the building its on! I plan on building a shed using panels as the roof! With panels on my house roof also. I hope to have. 4-6kw on the shed. And 2000-2500 or so on the house. Also atleast 1500-2000 on a small working garage. With a small DC grid connecting the panels to each . garage and house. So solar can be diverted to where its needed! It may not be the best idea. But seems to work?

  2. This guy's full of it . I've got some 20 year old Siemens panel's that produce as good as the day they were new. Now if what he was saying was true I'd be getting 20 percent less juice .

  3. Ohh ,this is just an ad..Anybody knows how much they selling them for??? He is funny saying that we will clean your panels to make them more efficient..LOL.

  4. The 360 watts panel is NOT a more efficient panel. It is just a bigger panel with more solar cells on it. A standard 250 Watts(grid tie-in) solar panel has 6 rows with 10 cells in each row, for a total of 60 cells(6 inch squared in size and 4.166 watts per cell). The 360 watts(grid tie-in) panels have 8 rows with 12 cells in each row, for a total of 96 cells(3.75 watts per cell),(24 more cells then the 250 watts panel and less watts per cell). The Black looking cells are in fact less efficient. This is because some of the Sun's light energy received by the black coated cell is converted into heat(Sun light is adsorbed by the black coating and turns into wasted heat).

  5. Yes, it is not only an ad, but a bit of a scam. You can't actually buy these panels. Only a Sunpower "certified installer" can install these. And this is so the installer can keep the price of the panels a secret and charge a huge markup on them. You can't compare it on price because the panels are unavailable to mere mortals. And you have to sign an NDE to be an installer.

  6. ALL DUDE DID WAS SPEAK CONJECTURAL OPINION. MONO/POLYCRYSTALINE PANELS ARE THE LEAST EFFICIENT,UNLESS THEY'R ON A SUN TRACKER,BUT AMORPHORUS PANELS,WHICH ARE THE MOST EFFICIENT FADE TO QUICK,DUE TO UV DAMAGE,AND LOSE CHARGE,OR COST MORE TO MAINTAIN,BUT ARE THE EASIEST TO SET UP. OTHERWISE,POLY WORK BEST IN HEAT,AND MONO WORK BEST IN COLD. HE SHOULD HAVE STATED OVERALL COST,AND DIVIDED BY WATTAGE,SO PEOPLE WOULD HAVE A IDEA AS TO OVERALL PRICING,AND EFFICIENCY.

  7. You would have to be an idiot to install solar in Australia. A friend recently installed at great expense a solar system on their roof. Their first bill was cut by $200 off a $430 bill; the next bill increased to $700 which they objected too. then their next Bill increased to $1400 with the condition if they didn't pay then the mains power would be cut off. Solar sucks in Australia as does the governments. In the state of NSW a large 1400 megawatt power Station was sold to a company for $1,000,000; & in two years that company has made an operating profit of $80,000,000. Australia is quickly becoming a banana republic with the political leadership at a very low ebb. People in Australia are forced to give back to the energy companies over 2/3 of the solar they produce free. Only Donald Trump would get solar in Australia.
