HC 2 PV Solar Envisioned

Hunter Creek PV envisioned. As mentioned in my previous blog, solar hot water is out, PV is in... Well how much could we save at Hunter Creek phase II if we were to go with PV. Off course you can hire an expensive consultant or go to the National Renewable Energy lab's website. (NREL is of course based in Colorado!) But anyway their page with the PV-Calculator is here (there are a few steps).
PVWatts' CalculatorThe app actually estimates the energy production and cost of energy of  grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, small building owners, installers and manufacturers to easily develop estimates of the performance of potential PV installations.

the image gallery below show the steps I followed to determine the location (zip code) and size, by zooming in on google map imagery and plotting the approximate roof area covered by solar panels.

After filling in the blanks and some assumed (default) values given by the PVWatts' Calculator it spits out the grand total.

Annual PV potential table
Annual potential Savings in kWh per year, broken down in a table per month.
kWh price historically in Aspen
Just to verify that the assumed 10 cents per kWh is correct I verified this number at http://www.electricitylocal.com/states/colorado/aspen/

At  10cents a kWh tat totals $12,349 per year. On all 4 buildings and a cost of that could be a potential savings  = $49,396

 How about the investment? That depends on the price of solar panels per kWh, this again depends on location and size of installation.

Price per Watt
$5.80 pe Watt = most conservative (Source Open PV Project, dated) $2.13 per Watt, most favorable, Sept 2016

The NREL website has an open repository of data of Solar projects historically as well as geographically, there is the most conservative as well as the most favorable scenario.

Most recent and most favorable number for PV solar pricing estimate

As well as the late cost benchmark quarterly analysis.

MOST CONSERVATIVE 77.3 x 1000 (kW) x $5.80 = $448,340 per building 

x 4 = $1,746,960 all four buildings

MOST FAVORABLE@   $2.13 = $164,649 per building

x 4 = $658,596 all four buildings
