Costs presented to consumers are all relative to who is presenting them.  Some contractors get a better price and install multiple units over higher effective units and some installers sell on the price but forgets to inform the consumer what they are really getting.

Lets review the TRUE COST of the presented low-cost products
over the SR1800 Solar Attic Fan.

It has been reported to us and we have seen it time and time again, installers and consumers purchasing on unit price. We hear it all the time, big box stores offers a product for $X and this is what the consumer is focused on, instead of the ‘true cost‘. If you only look at the cost of the unit and not the performance, then your not seeing the trees in the forest.

For proper ventilation (see below) or our page ‘Ventilation Basics‘ <click-here>, some installers and consumers are purchasing two to three of the lower cost products units when one and sometimes two of the SR1800 would be plenty. Also without stating the obvious, most are not taking into consideration all the feature benefits of the SR1800.

Bottomline: There are other products on the market but if you are going to purchase a product solely on price, then as an informed consumer the goal of this post and table is to show you the real cost per CFM (cubic feet per minute).

The purpose of proper solar powered ventilation is to reduce temperatures inside enclosed spaces throughout the year, like your attic, crawl spaces, warehouses, storage areas, sheds, barns, etc. In the summer, our solar powered attic fans help make all these areas more comfortable by converting passive ventilation to active. Thus reduces HVAC costs and cooling cycles, which also saves energy and money. The solar attic fans help reduce heat that can cause the premature deterioration of shingles, roof boards, sheathing, siding, insulation and stored valuables.

Proper ventilation is direct result of proper installation.
