Solar info re production of power. I have a query.

[azureline**]

Can someone explain in plain English please, if you have a 1.5kw system, how much solar power is it capable of producing per day? (maximum amount)

[izabsmiling]

Az, do you know the normalized power output or NPO of the panels ?

[izabsmiling]

these are good points 

* NOT all 1.5kW systems are the same

* Find out the NPO (based on real data from installed panels) of the brands you are considering

* Ask the sales person about reducing your power consumption (e.g. efficient pool pump, LED lights, solar hot water system, standby power)

* Ask the sales person for quotes on larger kW system to suit your actual consumption (have your recent power bills on hand when the sales person visits your home)

* Make sure you understand from the sales person how many kWh (based on NPO) you can expect the quoted system size to produce on an average day in summer and winter and how much savings that will translate to on your quarterly power bill.

That is what I am asking for, what can be expected from a 1.5kw system.

The 'real' amount may vary from one 1.5kw system to another of a different brand .the NPO of each system  is important as that gives more of an idea of the real amount that can be achieved outside an ideal factory testing environment.

not much, to effectivly negate your power bill it is said that the average house would need around 20 panels on there roof

Our installer says 6.93kWh. per day average.

What I want is to know is, how does that relate to a 1.5kw system? Does that mean for 92 days, we should produce 637.36 kwh?

That is not what I want to know. We have a 1.5kw system. If it is working correctly, it is enough for us. We sell back to the grid at .44c

[kilroy_is_here]

In an ideal period yes but that there are so many variables to take into account that effect the efficiency of the output each period could vary quit a bit

[azureline**]

yes, I understand that, just need to know if what someone told me is correct:

if a system is 1.5kw, he said it can only produce 1.5 kw a day so over 92 days it would be 138 kw.

If that is so, why would anyone bother doing it?

and less whatever we are using (from what we produce) we are being paid $220 for the 92 days.

Unless I misunderstood him........
