But even is we put all the panels on open land you can see here how much space it would take…

That little brown rectangle over in the Arizona area is what we would need to cover if we powered all of North America with nothing but solar. Given that solar will probably supply no more than 35% of our total electricity cut it down to about 1/3rd and send Canada and Mexico their share.

As for washing panels, it generally isn’t done. A test site outside of Tuscon didn’t wash their panels for over two years and when they did performance went up only 1%. Not worth the effort. Or water.

Though our planet is flooded with vast sunlight yet we are wasting huge quantities of electricity to light our homes, offices and commercial establishments.

The technology of capturing sunlight and taking into interior of rooms is well known. A dish antenna fixed on roof top can collect concentrated beams of sunlight, bundles of plastic fibers can take this light into interiors.

If this abundant sunlight is efficiently utilized at an affordable cost, we can save considerable amounts of electricity there by saving our fossil fuels like coal, reduce Green House Gas emissions and save our environment.

Some hurdles : (1) Harmful UV and Infra Red rays, (2) Tracking dish towards sun, (3) Automatic regulation of lighting in rooms

What we need :

(1) A suitable plastic dish mirror antenna of about 1.5 meters diameter constantly tracking towards sun. The tracking can be achieved by suitable pre programmed mechanical device, optical sensors or software program connected to GPS system

(2) As Infra red and Ultra Violet rays are harmful, they can be filtered at the dish itself. Instead of utilizing the direct rays from the dish they can be reflected on to a smaller inverted plastic auxiliary mirror dish and the energy tapped from the auxiliary dish.

(3) Bundles of flexible white transparent plastic fibers to collect the concentrated light from auxiliary dish to interiors rooms.

(4) An automatic regulating mechanism in the rooms to increase or decrease the level of conventional light depending on the intensity of arriving sunlight and also to switch off the sunlight when not desirable.

(5) All this at an acceptable cost.
