Stand-off building block systems for roof-mounted photovoltaic arrays
Technical Report
·
OSTI ID:5508276
A low-cost building-block array for roof-mounted, grid-connected photovoltaic installations has been developed and prototype-tested. The focus of this work was on standardizing the array mounting hardware and installation methods to reduce installed system costs. The targeted consumer price for the balance-of-system - all hardware and assemly/installation labor, excluding the purchase price of modules and power conditioner - was $50 per square meter of photovoltaic array (or $0.50/Wp for a nominal 10% efficient array). A cost of $40.78 per square meter of photovoltaic array (or $0.41 Wp) was achieved for the prototype installation.
