Component three - The Photo voltaic array and mounting system

The ultimate part of our guidebook to how the photo voltaic PV functions and exactly how it it truly is set up. This little bit explains how the array suits for the roof.

The solar modules are close to 1.5m by 1m and therefore are like a sheet of glass within an aluminium frame- the clever stuff is sandwiched inside the glass and laminate layers. These require to be mounted down securely along with the most frequent way of doing this is to build a frame they are then clamped to.

First of all we'd like something for your body for being anchored to. below are some roof hooks which can be generally utilised.

There are lots of sorts of rook hooks/anchors equally as there are numerous sorts of slates and roof tiles. In the majority of instances they are a set towards the joists of your roof. The roof tile or slate is then changed, more than the top in the hook leaving simply a tiny piece displaying - to which the frame is then fixed. With some types of roof material it isn't usually achievable to simply change the roof covering, with stone slates as an example. In these cases a substitute such as lead can be used to include the hook. In this sort of cases, the roof-covering must always be at the least pretty much as good as if the set up started out and also the roof integrity will never be compromised.

The hooks are quite solid bits of steel along with the the fixings employed can also be robust- the final factor you want is your array blowing away. Northern Daylight usually make use of a structural engineer once we design and style each set up and use calculations to ascertain the volume of roof hooks for use and what sort.

this is how the rail sits onto the roof hook, it is possible to begin to see the tile covers the hook.

The array mounting frame is then equipped on the roof hooks. The frame is made from aluminium and it is mild but very robust. Every one of the fixings becoming a member of the body on the roof hooks are sound stainless steel. You can find two mounting rails for every row of solar modules, a single with the leading and one particular at the base.

The modules are then clamped for the rail, below is actually a picture of the conclude clamp. The clamp, such as the rail along with the module body is produced from aluminium and it is connected utilizing chrome steel.

All the supplies employed while in the photo voltaic array are in the greatest good quality, developed specifically for their objective, with strength, balance and sturdiness in mind. Due to the fact we only use the very best and because we design each technique on the optimum expectations you can be assured that your method will be there provided that the roof or lengthier!

This is actually the most common approach of retro-fitting photo voltaic PV mounting installation. Coming before long is going to be a chunk about some of the other methods of solar giant mounting system.
