PCE offset for Alternate Energy Projects
Whom ever this concerns.. On the following pages is a proposal for the use of the PCE-fund to implement alternate Energy sources in Rural Communities. By thinking forward 20-25 years we can project some impacts. It is likely that the cost of oil will continue to rise, with that the cost of electricity in the Rural Communities will also continue to rise. Currently we have the PCE fund to offset that cost, however the historical trend shows an increasing amount needed for the Communities.Here…See More

Improving PCE
Addressing issues surronding the PCE program so the program encourages the public policy goal of low cost rural electricity.

Hi Don
I am using an Outback FM-60 Mppt,,
It allows me to connect strings of modules with higher Voltage rating
Up to 150 Volts
This saves on the wirering..
There is a small continues draw of a few mA for the controller'
But I have not seen…

HI,
Does anyone have any hands on experience with PWM and MPPT solar controllers? Would you share what your experience has been and the pros and cons that you have discovered for each type of controller.
Thanks

Hi all
does anyone know what kind of panels the PWatts calculator is based on ?
What kind of efficiency of the panels ?

Hi All,
There is a test being done by the cold climate housing research found http://cchrc.org/solar-power . If you take the 2009 PV production data and compare it to the information calculated by NREL's PV Watts calculator, actual electricity…

Hi all,
To follow are the theoritical output of an solar array and the actual measured output of the array. Based on 6 months of data the theoritical output is 30% higher than actual measured output.
What has other peoples experience been? Actual…

Hi just ran the numbers using PV Watts. http://rredc.nrel.gov/solar/calculators/PVWATTS/version1/US/code/pvwattsv1.cgi The production estimate used for the Noatak water plant closlely follows the expected output. Does anyone have a feel for how…

I'd like to see the Ruby data...I am not sure that the church has the best installation accomplished...when I was there last there were serious grid errors encountered and the system was done a significant time. I also question the angle of incidence for those peak months in the spring given the positioning of the array.
