Since distributed solar is “behind” the meter, customers do not pay the utility for the solar power generated. The cost of owning DER varies from state to state and among utility companies.

Distributed solar has so many cost factors that the price spike in polysilicon – which still accounts for more than 25% of module costs – barely changed the financial formula, enabling small-scale PV to dominate. Many countries have boosted rooftop solar with new policies but these are simply riding the wave, not causing it.
Since the distributed PV power generation system is an independent unit, the volume is small and the layout is scattered, which requires high operation and maintenance technology. At present, a scientific and all-around standardized distributed operation and maintenance system has not been established.
The unit operation and maintenance costs m are about 8.0639 $/kW a and units cost of distributed PV system is about 1.4515 $/W . Let the net present value of the cash flows in each financial year equal to zero throughout the whole calculation period, IRR can be obtained. (3) Static payback period = initial investment / annual net income.
Development of distributed solar photovoltaics mainly benefited from the incentive policies in China. Currently the cost of PV power generation is still higher than traditional energy sources. China's PV industry is incapable of competing in the energy market without policy intervention.
Except 100% grid-connected mode, the IRR of distributed PV power plants in three areas is higher than 8% which has shown good economic benefits. As subsidies continue to fall, the technology and cost performance of distributed photovoltaic (PV) determines the progress of its grid parity.
