    FYI...member Chris C. has not been here since the single day he posted on July 18th. The only reason this entire thread came back up was due to "AmitBajpayee" posting some mostly useless comments about solar energy.

        Energy payback time for a solar PV panel is between 1 and 4 years depending on several factors.

            That would be great. But there isn't a single market in the US that is free of either one of those things.

                If you really believe that document from the Federal Gov that I have a great bridge I can sell you.

                I have run the numbers and here in Florida and I can maybe get $1000 per year savings for a 6kw system. With a POCO rate of below 12 cents per kWh my calculations come to more then 12 year payback which is a lot more than what that document states.

                    And more sad parts from today's WSJ. Their article explains '' We Can't Build Roads Without Oil!'' The essence of their article is windmills and solar panels will not get roads built.

                        Without oil the country will grind to a halt even if we all switch to renewable energy and EV's. At least that is my opinion.

                            My opinion, we need to find ways to eliminate the polution that
                            will poison everything. In the process we will greatly reduce
                            use of fossil fuels, but never eliminate it. Bruce Roe

                                I really wonder if this membership is a bot that is test posting or maybe someone in India practicing their written English communication skills.
                                I might have misinterpreted the question, but, let me clear it out, I am a genuine user and not any bot. I answered about solar power usage and did not mean to explain any theories. Of course, I have opiniated about it, but I meant to say that solar power is the best renewable energy and it is environmentally friendly too.

                                    What I meant was that having renewable generation like solar is great but being an EE for more then 45 years I also feel that renewable energy is not enough to keep the lights on all the time. We will still need other power sources to do that or people will have to learn a lot about reducing their power consumption at night when most places will not have power even with batteries.

                                    I also feel the Nuclear energy is needed and green (does not release CO2) and we need to find a way to either eliminate the radio active waste or find a way to reuse it like they did in France for decades.

                                    But that again is my Opinion.
