Material Options

Material prices below are national averages; availability in San Jose may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
Monocrystalline Panels (Standard Efficiency)	$2,500 - $3,200 per kW installed	Good efficiency (19-21%), widely available, proven technology, 25-year warranties	Moderate efficiency means more panels needed, black frames may not match all roofs	Most residential installations - the default choice for good reasonGood efficiency (19-21%), widely available, proven technology, 25-year warranties
Monocrystalline Panels (High Efficiency)	$3,200 - $4,500 per kW installed	Highest efficiency (22-24%), fewer panels needed, best for limited roof space, longer degradation warranties	Premium pricing, the efficiency advantage is shrinking as standard panels improve	Small or complex roofs, maximum production per panel, homeowners wanting the best technologyHighest efficiency (22-24%), fewer panels needed, best for limited roof space, longer degradation warranties
String Inverter System	$2,300 - $3,000 per kW installed	Lowest system cost, simple design, easy to replace (one unit)	Shading on one panel reduces entire string output, single point of failure	Unshaded south-facing roofs with one consistent planeLowest system cost, simple design, easy to replace (one unit)
Microinverter System (Enphase)	$2,800 - $4,000 per kW installed	Per-panel optimization, shade tolerant, panel-level monitoring, no single point of failure	Higher cost, more components on the roof, slightly more complex installation	Roofs with partial shade, multiple orientations, or homeowners wanting detailed monitoringPer-panel optimization, shade tolerant, panel-level monitoring, no single point of failure
Solar + Battery System	$4,000 - $6,500 per kW installed (with storage)	Backup power during outages, time-of-use optimization, energy independence	Significantly higher cost, battery replacement in 10-15 years, adds complexity	Areas with frequent outages, time-of-use electric rates, homeowners prioritizing energy independenceBackup power during outages, time-of-use optimization, energy independence
