Is my house suitable?
Orientation of roof
The best orientation is directly South, but East and West facing roofs are also excellent and can have outputs of only 85% less than perfect south facing roof. The shallower the pitch of the roof the less important the orientation is. Therefore a very shallow pitched roof facing north may be perfectly acceptable.
The best pitch is typically between 30 and 45 degrees. The minimum angle for the panels is 10 degrees. We can install on flat roof but using a custom built frame to get the preferred angle (typically between 10-30 degree).
Shading of the panels should be avoided if possible.
Space on roof
There needs to be sufficient space on the roof for the panels. Our smallest system takes up about 1.6m x 1.7m.
Structurally sound roof.
The solar panels are not heavy but the roof needs to be strong enough to take the extra weight.
Hot water Cylinder
A solar thermal system will always need a compatible hot water cylinder. We will need to replace your current cylinder with a new high insulated one with an extra coil for the solar. Solar cannot be used with a combi boiler.
Conservation area and listed buildings
Although most councils are very pro solar some buildings may need planning permission or building consent. Rayotec employ planning consultants to help us to get permission to have solar panels installed.
