The final element of our information to how the photo voltaic PV functions and exactly how it it's put in. This little bit clarifies how the array fits on the roof.

The photo voltaic modules are about 1.5m by 1m and they are similar to a sheet of glass within an aluminium frame- the intelligent stuff is sandwiched within the glass and laminate levels. These need to become mounted down securely and the most common method of undertaking this really is to build a body that they are then clamped to.

To start with we'd like one thing for the body to get anchored to. below are some roof hooks which might be typically utilised.

There are many varieties of rook hooks/anchors equally as there are various sorts of slates and roof tiles. In most instances they're a set towards the joists of your respective roof. The roof tile or slate is then changed, over the highest from the hook leaving simply a little piece showing - to which the body is then set. With some varieties of roof content it isn't constantly attainable to simply exchange the roof masking, with stone slates by way of example. In these circumstances a substitute such as guide can be utilized to protect the hook. In these kinds of cases, the roof-covering must always be at least pretty much as good as once the set up commenced and also the roof integrity won't ever be compromised.

The hooks are very sound bits of metal and also the the fixings utilized may also be robust- the last factor you need is your array blowing away. Northern Sunlight always use a structural engineer whenever we design each and every set up and use calculations to determine the number of roof hooks to be used and what form.

The array mounting body is then fitted for the roof hooks. The body is produced from aluminium and is also mild but quite powerful. Each of the fixings joining the body on the roof hooks are solid stainless steel. You'll find two mounting rails for each row of solar modules, one at the best and one in the bottom.

The modules are then clamped for the rail, under is actually a photo of the conclude clamp. The clamp, such as the rail and the module body is produced from aluminium and is connected employing chrome steel.

All of the components used within the solar array are of the highest high quality, designed especially for their function, with power, security and sturdiness in mind. Simply because we only utilize the best and because we design every system towards the optimum requirements you'll be able to be confident that your program will be there provided that the roof or more time!

This is the most popular technique of retro-fitting photo voltaic PV mounting installation. Coming before long will be a chunk about a few of the other methods of solar giant mounting system.
