I have really really like experiencing your own you tube video regarding
The roof. I recently started in roofing plus found your remarks to be
extremely helpful. I look forward to examining more of your own video
footages. Can I inquire how long you have happened to be in this kind of
Commercial Solar Panels are too Expensive !!

You’re really doing a disservice to solar when you claim it’s not NET
energy. It’s well understood by anyone investing in solar that the ‘free’
electricity only comes *after* the system has generated more than the
system cost. The cost of electric power is going to continue to climb. The
higher it goes, the faster the system earns it’s worth.
HA HA HA didn’t have to just switched hands. Your right the info is there
but you really have to dig to find it. Coast of this system is better BUT
it still takes too long to pay for itself. About 8 to 10 years. I am
looking for something that will pay for itself in Less, than 4 years.
Thanks for the heads up though. And you have a great weekend.
Yeah, yeah. I’ve read that article, and all the stuff on the Delaware U.
site. It’s an impressive achievement. Todays panels can be anywhere from
5%-25% efficient, but those figures a irrelevant. The bottom line is what
the panel *produces*. A single 1 sq/m panel theoretically receives 1kW of
energy, but may only deliver 170W, but that’s *STILL* 170W of usable power.
Winter days are shorter and the angle of the sun is low. Both contribute to
loss. Yet at todays prices (assuming $.12/kW), 4kW/h is more like $.50
worth of power *AND* it’s enough to supply the needs of the video’s maker.
It only stands to reason that with longer days and a proper angle that it
could generate even more.
Here is a way that a residential house could effectively store solar energy
during the five hours of good sunshine, to last for the full twenty-four
hours. Use a hydraulic elevator system lifting a very heavy weight, where
the energy is stored by the gravity of the weight. When the sun goes
down,or when more power is needed during the five hours of good sunshine,
the very heavy weight movement is reversed and the hydraulics is used to
