Alpha SolarSmart 100 - General Information
3.6 SOLAR COLLECTOR INFORMATION
The solar collectors are certified and are in compliance with the Solar Keymark Standard. They can be mounted on all roof
types with the use of the appropriate fixing kits available.
The solar energy supplied by a system varies with the orientation and tilt of the collector, which will usually be determined
by the existing roof. However, the predicted variation is slight. For a collector facing anywhere between SE and SW and
tilted between 15° and 75° from the horizontal, the annual solar energy supplied will be at least 90% of that obtained at the
optimum collector position (South at 30°).
It should be remembered that shading from trees, buildings etc., can produce a significant decrease in system performance,
and collectors should be positioned to minimise shading from the sun.
One solar collector is required, upto a maximum of two collectors can be installed using one of the following methods:
a. Integration of the collector into the tiles of a pitched roof.
Using the Alpha In Roof Flashing kit (portrait or landscape) collectors can be integrated into the structure of a pitched
roof as shown in Fig. 7. The roof must have an inclination of more than 15° and the tiles used with the flashing kit must
be suitable to ensure that the installation is weatherproof. Full details of this type of installation are provided in the
instructions supplied with the kit.
Note:
When using two panels only a portrait flashing kit is available. If two landscape panels are used then use two
individual flashing kits or two On Tile kits.
