Element 3 - The Photo voltaic array and mounting program

The final element of our information to how the photo voltaic PV functions and exactly how it it really is mounted. This little bit explains how the array fits towards the roof.

The solar modules are all around 1.5m by 1m and therefore are like a sheet of glass in an aluminium frame- the clever stuff is sandwiched while in the glass and laminate layers. These want for being fixed down securely and also the most typical way of carrying out this is to build a body which they are then clamped to.

For starters we need one thing for the frame to be anchored to. under are a few roof hooks which are frequently utilised.

There are numerous types of rook hooks/anchors equally as there are numerous kinds of slates and roof tiles. In many situations they are a set on the joists of your respective roof. The roof tile or slate is then changed, over the very best in the hook leaving only a little piece showing - to which the body is then fixed. With a few kinds of roof materials it's not at all usually attainable to simply change the roof masking, with stone slates for example. In these circumstances a substitute this kind of as lead can be employed to cover the hook. In this kind of situations, the roof-covering should always be at least nearly as good as once the installation commenced and the roof integrity will never be compromised.

The hooks are extremely reliable bits of metal and also the the fixings used will also be robust- the final factor you need is your array blowing absent. Northern Sunlight often use a structural engineer after we design every single set up and use calculations to ascertain the amount of roof hooks to be used and what type.

The array mounting body is then fitted for the roof hooks. The frame is made out of aluminium and is light but extremely sturdy. All of the fixings becoming a member of the body for the roof hooks are reliable stainless steel. You'll find two mounting rails for each row of solar modules, one with the best and 1 at the bottom.

The modules are then clamped to the rail, below is a image of the end clamp. The clamp, like the rail and the module body is produced from aluminium which is related employing stainless-steel.

Each of the resources employed while in the photo voltaic array are of the optimum good quality, made specifically for their goal, with toughness, balance and sturdiness in your mind. Due to the fact we only use the greatest and because we design and style each and every method for the greatest expectations you'll be able to be self-confident that your system will probably be there assuming that the roof or lengthier!

This can be the most frequent method of retro-fitting photo voltaic PV mounting installations. Coming quickly is going to be a piece about a few of the other methods of solar giant mounting systems.
