There are other solutions to provide attic ventilation such as turbine vents, power ventilators and others but in terms of energy efficiency; however, the solar attic ventilation is one excellent option. This type of ventilation system is an eco-friendly way of extending the life and durability of the home. Note that if the roofing is high and sloped in such a way that there is not much movement of air upwards or downwards, it can be difficult to circulate the air in the attic. To fix this situation, you need to set up a solar attic ventilation system. To install a functional solar attic ventilation system, here are some tips for you.
Make it Part of the Design Prior to Home Construction
The best practice for solar attic ventilation is its inclusion during home construction right from the start. The construction roofers can incorporate solar roof vents very easily for the solar attic ventilation and you can certainly save cost on hiring an electrician to do it later. Any further retrofits can be done easily by using conventional tools and construction methods without major rehab as compared to when it wasn’t considered as part of the original construction plan.
Options for Mounting
It is most preferable for solar roof vents to be flush mounted along the roof line in order for it not to interfere with the general appearance of the roofing. Roof vents can be curb-mounted. These are applicable to tiles or flat roofing and gable mounted vents with wires connected to the solar panel at the roof.
Consider the Quantity, Size and Location
From practical standpoint, the more amount of air movement in the attic, the more cooling effect it can bring to the over-all temperature of the house. So it is practical to consider multiple vents or even the bigger size of such to achieve the desired effect. But of course this has to be based in accordance to the form and size of the attic and the budget. For the roofs with high slopes as mentioned from the start, solar attic fans will definitely not be appropriate on those facing north or any roofs that are completely shaded. Another practical consideration is to install solar roof ventilation only on the portion of the roof where sunlight is present for the longest period of time otherwise, it will become inefficient since power will be dependent on the presence of sunlight. If budget is not tight for the project, attic fans that are electric powered can be installed over areas not much exposed to sunlight.
You must check the prevailing residential regulations imposed by the country where you reside. In some places, housing code inspectors check the equipment installation of attic solar ventilation due to its effects on the house readiness or safety during hurricane or typhoon situations. The U.S. requires all solar attic ventilations to meet Section R806.2 of the International Residential Code which is part of the requirements in building new homes. Also, local building codes may specify certain standards when it comes to attic ventilation installation so you should check your local building regulations first before you start working on your solar ventilation system.
