I don’t generally want a hot shower at noon, especially when it’s 90 degrees and sunny. (If it’s a weekday, I’m likely not even home.) My elderly neighbors, in contrast, may want to run their air conditioning at a low level just about then. By having my small solar array attached to the grid, my power can offset the spike in their demand at the right time. Now, multiply by a few thousand. Sure, inverters and cells require energy to build and transport, and they don’t last forever, but…20 years or more? Not too shabby. (Not knocking batch solar water heaters, mind you.)

This company quietly goes about the business of actualing creating and selling energy every day, signing contracts and building facilities while the others talk about their plans and emerging technology.

Solar is here and like the automobile replaced the horse will replace the archaic energy system we now employ

In the UK, cleantech data provider Library House is in admistration and in the US, the Cleantech Group laid off one third of their staff, gutting their research team.

Yes maybe you only save a few kilowatts, but if everyone is saving a few over the population of 300 million (USA alone) ppl, it is quite a bit of help to the environment. Maybe not an answer, but maybe those few extra decades we gain will be enough for our tech to advance far enough to make it even more meaningful. Besides, even 1 kilowatt is 1 kilowatt less burnt from fossil fuels. This is assuming the carbon footprint in the manufacturing of the panels is also very low which it seems to be, especially in the case of first solar.

If oil sands with an EROEI of 2 make sense, then solar voltaics makes sense.

Solar performs during times of peak power, so comparisons need to be made against peak power production. Add to that the carbon footprint and you have the basis for a solar economy.

Further, we have a new administration with a mandate. Do you think the new American President will ignore this sector? I’m a buyer.

If we could start getting small-scale back-up applications of alternative energy sources in new construction and retrofits we might get there faster. Basically, we have to stop looking for a single do-everything energy source and push for a multi-source model.

That I agree. But, solar is growing near parity with cheaper sources. Not to mention, volatility is a killer (just look at the per KW hour charge over the past few years). Solar can help minimize this. To make it solar viable, regulations, scale (in the form of utility or individual), storage, and an upgraded grid are needed.

Photo-voltaics while feasible as a technology do not represent a practical solution in most applications – especially if we consider the replacement cost of batteries or grid-adaptive inverters. Sunlight is much better as a source of heat rather than electricity. Any big-box retailer can capture a lot of heat from the roof in the winter and can use evaporative water cooling in the summer. Even more practical than sunlight is bottled up sunlightin the form of solid fuel, which is a fully renewable resource. Do not buy an electric envelop sealer if a damp sponge will suffice. Honestly if the fund managers spent less time speculating and more time doing their research, there would be no shortage of energy.
