Under $2k / kW installed is a great price! Pricing has been coming down significantly recently and it looks like you've got some good payback in your system.
Perhaps you're the leading edge of the curve for new installations. I looked at it 24 months ago and it was not a positive pay back model at the time.
Here is an undated article from Hydro suggesting it is $3k / kW, takes 8 square meters per kW, has a 25 year life expectancy, and over a 25 year pay back. Again that's based on $3k / kW so if you're installed at $2k / kW you are doing well.

Copy and Paste of the metrics here;
In B.C., a 1 kW solar PV system, south facing and tilted with no shading, will generate about 1,200 kWh per year or about 30,000 kWh over its 25 year lifetime. This is taking into account an industry average solar panel efficiency degradation rate of 0.5% per year.
At a turnkey installation cost of about $3,000, it would take you over 25 years to recoup your investment at today's average electricity rates.
(In remote locations where there is no grid to tie into for power, off-grid solar PV systems can be used to store power in batteries which can be used throughout the day or even at night. In B.C., off-grid systems make for a sound investment when installed in locations where alternative power sources such as diesel generators are required.)
