What you can expect your SOMAH project to cost
The price of a solar photovoltaic (PV) system is determined by numerous factors, including system components and configuration, the difficulty of installation and available incentives. The cost of a solar PV system is measured in dollars per watt. The current average installed cost per watt for a multifamily solar PV system is $2-4 per watt. This means the average 70-kW multifamily system will cost $140,000-$280,000, prior to tax credits and incentives.
