Advice for minimum requirments to build starter PV system. - Page 4

 

   Perhaps, but my system is still waiting for me to whip out my calculator.
Meanwhile, it has been chugging along for about the last 6 years with nary a
problem.  It was really quite simple:  I started out with an old 70 watt panel.
(70 watts 'cause that was the one I was able to scrounge.)  Then I bought an
appropriately sized charge controller (still no calculations).  I have 2 amps of
load for 4 hours a day.  (8 AH.  I can do that calculation in my head)  My
generator battery (80 amp hours)can easily handle several days of autonomy and
still have enough left to crank my battery.

    This is not rocket science.

Well, just like wayne you have told us what you have but not what it
actually runs, sounds like a single 20W globe.

I am sure everyone is impressed.

 

   Well, you have compared me to someone I don't even know, and you have made
(wrong) assumptions that you did not need to make about my system...

   Now you have made assumptions about how "everyone" must think about my
system.

  Do you suppose that I was trying to "impress" someone?  ...or do you suppose
that I was trying to make a point about a system that is very much like the one
the OP is contemplating?  Interesting how you ignored the thrust of my post and
tried to change the subject.

Bye.

There is no need to test the water. Solar will run your shed, and yes,
it can even run your house.

Your best bet is to learn the correct formula for sizing and design of
systems.

As for the rest, panels - regulator - batteries - and an inverter if
you require 110/240 volts.

And don't forget some wiring skills.

What's your estimate of the number of watts you need and for how many
hours a day ? You can't intelligently design a PV system without that.

Also it's important to know where you live to check the insolation data.
