i think they are £10 a panel. 

Edited by Russell griffiths

Those are smaller than typically used for domestic solar pv but I see no reason why not to get 40 of them or perhaps 42, for a 3.8 / 4kWp system. for a cost of £400

 

Probably best suited to a ground mount scheme, they might look a bit odd with such small panels on a roof.

Here is a more readable version of the data sheet

Things to note

1) None of the variants produce 97Watts, 85 to 95 Watts.

2) They have no bypass diodes, they will be very sensitive to shading

3) With an open circuit voltage of 60.5V it will limit the number in series for a given inverter, rather than about 30V for silicon

4) Will occupy around 8m2 /kWp as opposed to 5-6m2 /kWp for silicon panels

5) Should produce 5% more per kWp than silicon

6) Production in low light conditions should be greater than silicon (10%?)

7) Will not suffer as much output degradation at high temperatures as Silicon,  0.25%/°C rather than 0.37%/°C

Now I have had a better read, add to the list of "issues" that they are frameless, so mounting them will present a whole lot of challenges.
