My roof goes photo-voltaic
If you follow me on Facebook, you already know this, but this past fall I added the first of 15 photo voltaic panels to my roof. Another 15 coming in the next few months.The system was "sized" to produce about 14-15KWH per day, but I'm usually producing between 14 and 18KWH per day. And that is in the winter time!
My daily electric usage averaged around 40-45KWH per day. The pool pump is the biggest offender (at around 10KWH per day), but I'm putting in a more efficient pool pump this month.
The system has been operational for the last 3 months and I'm VERY pleased at this point. Here is my the average daily usage for my last bill. I'm down to about 20KWH per day that I have to "buy" from the electric company.

Do you have to clean the solar panels? I've been hesitant to take the solar plunge because getting up on our roof is.... not easy.
Thus far, I just washed them off once with the hose. They are actually REALLY sturdy, though. The installers actually sat on them and walked around them (on the edges).

Very cool, how long until the savings from your electric bill equal or surpass the cost of the solar panels.
Thanks

At the current cost of oil, around 7 years. That is, of course, after including the tax rebates in the equation. State of Hawaii offers a 35% tax credit and the federal government has a 30% tax credit.
It is a better feeling to know that I'm not contributing as much to the purchase demand for foreign oil. This is more for socio-political reasons than environmental reasons, though.
WOW; quite interesting
Do you have any specifics on the technologies you have used; this is very interesting, and in the West Coast of Ireland a technology that is not discussed at all.
I'm interested to know where you purchased the panels and how you decided on the unit you purchased.
It would be great to have some kind of numbers. and yeah, how did you come up with this brand of solar panels?
