Roland Said:

Do I need a specific solar license to install PV panels ANYWHERE in the US?

We Answered:

I think it goes state-by-state. In California, a C-10 contractor's license is enough to put up panels and connect the necessary equipment. Check the site below, there are materials for exam prep.

Maybe some places don't have the licensing requirements, but in general, if you're Joe the Plumber in Michigan, you're Joe the Handyman in California until you get the local license.

One more thought, if you're working for an installation company, if you're under the "supervision" of a licensed electrician, I think you're good. But you might end up doing the grunt work and not paid for your full skills.

I have a question on PV system/Solar Panels?

We Answered:

Location?
Number of hours of direct sun per day?
Do you have a south facing roof? how large? Is there any shade on it at any time of day?

Grid Tie or "off the grid" ?
Do you want to totally power your house or just partially?
How much electricity in kW-hours do you use per month in the summer? in the winter?

If it's "off the grid", how long a sunless period do you want the system to provide power? how many days?

Do you have a space for a bank of batteries if "off the grid" ? how big?

How much money do you want to spend?

caculating out put pv solar panels?

We Answered:

A 150 watt PV panel will give you 150 watts peak production at maximum exposure to sunlight. If you have a 5-hour solar day, yes, this gives you 750 watt-hours. Please not the watt-hour is a different ritter than the watt; i recommend you Wikipedia both to learn more :P

But, in a nutshell, the watt is the amount of work that can be done Right Now! whereas the watt-hour is a calculation of how much we've consumed over time.

Bernard Said:

Did you know that solar PV Panels are more efficient in colder temperatures?

We Answered:

I did not know that...

and the funny thing about nuclear power is that it's not that expensive to build... but it creates a lot of hazardous material... and that stuff is expensive to get rid off...
