  1. REAL Free energy technology exists!But the Establishment doesn’t want ppl to know this,Get the blueprints for a real Magnet motor free enegy machine at LT-MAGNET-MOTORdotCOM ,Start the energy revolution!

  2. @williamsharkey Very intuitive but didnt you notice that this was a video made for the uk….thought you would’ve picked up on that given your powers of observation!

  3. @kricotas Hi Kricotas. I’m not familiar with the products you have but if your inverter is rated 1.5kW then you could go to about 20 x 85W solar modules (panels.) The suitability of your batteries depends on their collective capacity rather than their number.

  4. @windymac
    question? i have bought 85 watts solar panel
    im trying to intend to buy slowly solar panels i dont have that much money
    i di buy sunforce charger Cont, ineverter 1500
    18 bateries
    how many solar panels i sould stil buy?
    thank you

  5. @youtubasoarus Ohhh trust me. thay’ll find a way to tax the snot out solar power. It’s what Governments do.

  6. I invented a breakthrough source of energy, which contradicts the law of conservation of energy. I have a PROOF that there are electrodynamic phenomena which contradict the law of energy conservation. It will cost about $1200 to make a 6 kW generator in mass production. Value of the energy produced yearly about $5400. I am looking for $300 000 for a prototype and for $3M for patents.

  7. dzgfdg – You need to educate yourself before authorising on a subject. First read about feed in tariffs. Now get your calculator out. Deduct 12,500 from 25 x 850. That’s how much the householder with a 2.4kw system will make on the feed-in tariffs. Now you need to add to that the 20-40% saving on their electricity bills (that’s indefiniteiy by the way.) Add the fact that the value of their property increases by the cost of the installation. There are some idiots here and you’re one of them.

  8. PV is a waste of money, idiots think they are going green. concentrated solar power is the best alternative, but still not reliable

  9. I invented a breakthrough energy source which violates the law of energy conservation. I have a PROOF that there are electrodynamic phenomena violating the law of energy conservation. I am looking for $30000 for a prototype and for $3M for patents. In mass production it will cost $1200 to make a 15 kW generator, value of energy produced YEARLY about $10000.

  10. @moviedude22 — The problem is profit and conflicting interests in what is profitable. If everyone was using solar power from the sun, nobody would pay energy companies, who make billions, if not trillions of dollars per year.

  11. Every hour enough energy reaches the earth for to meet the need for one year?
    Yet in a video titled “How Photovoltaic Solar Cells Work”, they state every minute enough energy reaches earth to meet the need for one year. So which is it, you can’t both be right. Maybe neither of you are right? I don’t know who to believe these days….maybe I’ll just make up my own reality…

  12. My question is – what if a hail storm were to damage the panels? Who would replace them, and at who’s expense?

    In the past 20 years, the demand for solar energy for domestic energy purposes has grown by up to 25% per year. With energy costs constantly increasing, governments are looking to solar energy as a more viable option to meet a growing need for energy. Pacific Crest Transformers has more information on this. You can also read whitepapers and articles on alternate energy at the Pacific Crest Transformers website

  14. Great video…I converted my home to a net-zero solar powered home that uses no oil or gas…I made a video about it called, “Preparing for Peak Oil”….

  16. If you have the chance have a look at the book “The Solar Fraud” Why Solar Energy Won’t Run The World by Howard C Hayden. It is an interesting read but a bit difficult to find. Any public library should be able to get it though.

  17. You a few good points but the subject is rather vast to be discussed just with a few lines but keep this in mind. Solar and wind energy are unreliable therefore they need the grid and conventional or nuclear power anyway to back them up. These renewables DO NOT add power to the system, they only save a bit of fuel.
    For example 40-60bln$ on PV lasting 30 years (and they don’t) only allow to save 30×0.01x7bln=2bln$ in nuke fuel + installing the nuke power station anyway. 40-2=38=bad deal

  18. You’re exactly right, but tax incentives are a way of life. Why should my federal tax dollars pay for a TSA employee at an airport in Idaho when I live in Alabama? The previous solar slump is a thing of the past. As we continue our dependence on foreign energy, rather than capitalize on a huge opportunity to become the leading exporting nation of solar and other forms of alternative energy, we’ll continue to slip further into debt and become vulnerable to attacks, in more ways than one.

  19. If it makes sense you are welcome to install them but remember: subsidies distort the real market and pass the costs on someone else and I can provide you with real data where PV became obsolete after 9 years. Warranties are only worth the duration of the company that can honour them.
