How much will a 2.5kW IPP system cost?
Typically, a direct coupled (non-battery based) grid connect system will cost $10 per watt installed. Total system cost for a typical direct coupled system would be approximately 2500 W x $10/W = $25,000. This is a general estimate and costs will vary. In many states, a rebate, buy down or tax incentive is possible.
