The calculator above assumes that the LOWEST a system costs to install is $4 per watt DC.
If you are installing it yourself the cost is more like $2/watt D.C.
Is there any solar calculator out there that will allow you to enter in lower cost values and give you all the financial benefits like break even year, savings, per month/year, etc.
This site below lists a few, but wondering if there is something better as that artical is 4 years old.
I know I could do the calculations manually, via pvwatts but I'm lazy.
