Solarwise Group has a wide range of solar roof solutions:
We can supply both monocrystalline and polycrystalline.
Are made from a single source of silica. This makes monocrystalline solar panels more expensive. When space is an issue it would be better to use monocrystalline solar panels as less panels are required
Are made from multiple sources of silica, thus making polycrystalline solar panels cheaper. The downside of this is that you will require more polycrystalline solar panels to achieve the efficiency of a monocrystalline solar panel.
Sun tracking solutions maximise the amount of the suns rays it captures as it ensures the solar panels are always perpendicular to the sun. As sun trackers are not cheap, Be aware that it may not be cost effective to spend on the additional tracker and mechanisms just for 3-5% extra sun.
Solarwise Group is happy to discuss potential solutions and alternatives for your individual requirements - contact us for discuss this further.
