    You are taking a CUF of 35% which doesn't happen in real life. In reality its closer to 20% even in India (except maybe deserts).

    Secondly much of this generation occurs in the summer season, practically none with monsoon and much reduced in Winter. So when we talk storage, you need to get yourself storage to cover the seasonal variation which is in the order of several months of backup power.

    Which is what makes solar so incredibly useless. And the reason all solar plants are essentially dangerous gas plants.

    While the policy of feed-in tariff may work beneficially for a few (ps where's the installation cost, battery replacement costs?) who during periods of non generation (which can randomly occur for days) can simply leech of the deadly fossil fuel generated grid electricity, it has practically zero relevance for global energy consumption which is on the order of 600 EXAJOULES.

    There is only one clean source of energy that can rapidly, cost effectively, with a minimum land footprint, without requiring millions of tons of steel, aluminum, copper and toxic rare earths along with billions of tons of concrete; be used to phase out the deadly (7million annually) fossil fuels.

    Any guesses?

    Bangalore has 300 days of sunshine. Even during winter we get many hours of sun.

    The only time Bangalore becomes cloudy is during rain, and that mostly closer to when the sun sets or before sunrise.

    Sunshine doesn't automatically equal production.

    A solar panel will produce nameplate power for at most a few minutes of noon in peak summer. CUF of 35% is fantasy

    Nope, 20-25% load factor is possible even in the cloudy, rainy UK.

    Fine, even if the power generated is half, you are still in profit. Hell, you are in profit as long as you break even and then don't pay an electricity bill for the next 25 years.

    Thanks to solar promotion policy.

    Nuclear plants still sell power for as low as Rs 2.1/unit.

    I don't get power at my house for 2.1 though. I gotta pay premium.

    A small fraction of energy in India is prodced by Nukes. None for Karnataka. Besides you will have to pay far more for solar generated power. (Ref: Germanistan)

    Karnataka gets some power from Kaiga and Kundankulam.

    http://www.thehindu.com/news/nation...lant-to-get-two-more-units/article7331411.ece

    We pay a lot.

    This is for 2016.

    Solar power with backup will insulate you from increasing tariffs for 25 years.

    Should know better than to use wikipedia. Old data for non-tracking polycrystalline arrays and thin film, which comprises most legacy farms. 20-25% is possible with 2-axis tracking monocrystalline arrays and more with concentrator photovoltaics but 2-axis PERC monocrystalline is the best kWh/£ right now.

    There's also the issues of distribution costs for centralised generation like nuclear, especially to remote areas.

    That's not a lot. Where I live, we have R3 till 100 kwh, R6.73 till 300 kwh, 9.7 till 500 kwh, 11.2 to 1000 kwh.

    Any way, we have digressed, the point is that nuclear is awesome and solar sucks.

    Lipstick on a pig.
    All the inhabitants of remote areas would prefer to have reliable grid supply rather than freezing their ass to death come Winter. Nevertheless solar is still costlier.

    It's called a technology advance, just like new nuclear reactors are more advanced, except solar power relies on semiconductor technology, which is advancing at a faster rate.

    Sun still shines in winter. Batteries, solar thermal, thermal storage.

    Using modern design for the LFTR core, a reactor with a 6.6m long by 0.7m wide core, and a meter thick thorium-conversion blanket, generates 220MW electricity “in a simple to manufacture design that can fit within a tractor trailer for transport”. D. LeBlanc / Nuclear Engineering and Design 240 (2010)

    Suck on that Moore's law
