Ideal roof angles are complex, in the days of FIT it was simple, the angle to give max return which is facing due south pitched about 35 degrees.
However if you need to gain the maximum usable power it can be very different.
You need to ascertain when and how you are using the power. For most domestic installs an East West roof can be far superior, although only yielding about 85% of the output, the usable power can be far higher, sopince most domestic consumption is early morning late afternoon.
For a southern pitched roof again a higher pitch will give a higher winter yield good for heating , though not so good if your main use is cooling at midday in the summer when a pitch of about 30 is perfect
Maintaining grass quality during mid-season grazing is important. Farmers can maintain quality by entering ideal grazing covers of 1,300 – 1,500kg DM/ha, and grazing down to a residual of 4cm every rotation.
If you are now in a situation where cows are not cleaning out paddocks as well as they should be, leading to the development of steamy grass within the sward, here are some options.
Common options for rejuvenating swards include:
Take a silage cut, probably into bales, remove the material and start again with the aftermath...
