Grasshopper Solar

Although I received an annual revenue estimate, assuming no shade, in order to get the more accurate estimate I had to pay $4500 upfront as I was buying the system. Their technician then spent one hour at my house with a meter and then they produced a new set of figures, based on the actual shading. Unfortunately, it turns out that the roof on my neighbour’s house, which is 16 feet from mine, casts a significant shadow from mid Oct. to mid March, which is largely responsible for a 23% loss of projected revenues which led to a payback period of about 15 years, which is not acceptable.
I was very thankful that they found this before I spend any more money but I was astounded that they would only refund me $2000 out of my $4500, leaving me paying $2500 for one hour’s work from the technician on site plus their subsequent work which was probably done mainly on the computer. I suspect their real costs are between $500 and $1000.
The best advice I could give you is that before going solar you watch the shade on your roof, particularly between October and March. Also, be forewarned: if you are buying the system, you will be paying $2500 before you get an accurate estimate of your revenues.
Also, I notified them September 21 that I was not proceding but it took 4 phone calls and almost a month before they sent the cheque.
