The mayor calls it the cities SHOWCASE project, why hide it?
The only city in western Canada with its own hydro electric plant puts solar panels at the dam. and lets cleaner greener waterpower and its profits spill down the river for the mayors green vote.
The Nelson solar garden data is now available on line, click here.
This tells you daily power earned, who can make heads or tails of that? I asked them to provide weekly, monthly and lifetime energy. They say they can't. BS. They won't somebody might figure out this is worthless.
There are dozens of public solar projects offering all the data.
Banff for example provides all kinds of data.
Notice above I can click on daily 1D, weekly, monthly , YTD shown- Year To Date
Upper Lifetime 85.4MWh
Solar panels were installed on the roof of Banff Town Hall in August 2013. It's a 18 kW system with 72 panels that generates 17,500 kW hours of electricity each year.
Let me show you some of what this tells me.
Lifetime 85.4MWh or 85,400kWh since installation Aug. 2013, an 18kW system.
85,400kWh/64mo. =1334kWh/mo avg x 12 mos = 16012kWh/yr.
presume electricity is valued at Nelson residential retail today 10.36c/kWh x 16000kWh=$1657/yr
Lets use Nelson solar garden installed cost per watt $5.90/watt
System 18,000kW x $5.90/watt =$106,200 system cost.
Business case borrowed 3.5% for 25 years is $531/mo for 25 years of $6372/yr
Paying $6372/yr to make the equivalent at full retail of $1657 in power, pretty expensive power.
That is why Nelson won't show any meaningful data.
Let s do the Nelson Community Solar Garden calculations.
They admist to $339,000 install plus security cameras, stolen copper, stolen solar panels and security cameras and other costs all extra. I suggest $400,000 isn't out of line.
Borrowed over 25 years at 3.5% thats $2000/mo for 25 years or $24,000 annually.
Nelson hydro makes power for 2c/kWh and buys half from Fortis for 4c/kWh, avg 3c/kWh.
Annual solar garden power if made from clean green waterpower 61,000kWh x 3c/kWh =$1830
Selling that for 12c/kWh would get us $7320-$1830 = $5500 profit lost.
Lost profit of $5500/yr + $24,000 system business cost payments/yr = Total cost $30,000.
Plus the solar garden increases our carbon footprint, why did this happen?
The manager of Nelson hydro brought city council a business case.
Our solar garden in winter when we could use power, worthless.. |
If we could see some of the real data we could see how shading affects panel power output, they won't show us. Who would install solar panel systems so the front row shades the back???? |
