Estimating the cost of net+supports
Last updated atÂ
The average cost of SolarNets material is somewhat variable, depending mostly on the number of nets and supports.
Estimated price per square foot of solar modules $5.50/sq. ft.
Estimated cost per covered solar module $120 each
Estimated increase in system cost for 20 modules $2400
Representing a system cost increase of 7.5% for a $34000 purchase price of a 20 module system.
If multiple nets are needed due to an irregular array shape, the cost estimate should be increased by about 10%.
The above estimates include the nets, supports and shipping. Sales tax will need to be added for California residents.
Based on the typical replacement cost being $2000 per event, the net cost is about 6% of the cost of replacing a damaged module. $120/$2000 = 6%
Replacement cost of the net material alone is approximately $1.50/sq. ft.
