Net metering quality

Quality of net metering policy (higher = better for solar economics):

Excellent — Full retail NM + SREC

What this means

Excellent net metering means every kWh you export is credited at full retail rate, making solar very profitable.

Example: 900 kWh/month household in Maryland

At 4.5 peak sun hours and a 400W panel, you'd need approximately 19 panels (7.6 kW system) to cover your usage. That produces ~10,735 kWh/year, saving about $1,825/year at the 0.17/kWh local rate.

Going solar in Maryland

Maryland, in Maryland, USA, has 4.5 average peak sun hours per day — good for solar. The local electricity rate is $0.17/kWh, which is above the USA average.

Net metering in Maryland is rated excellent. Full retail NM + SREC. This significantly affects solar payback: with excellent net metering, every excess kWh you produce is credited at full retail value; with poor net metering, exports may be worth only 10-30% of retail, making battery storage much more attractive.

Available incentives include: MD SREC market, Property tax exemption. These can substantially reduce the upfront cost of solar and battery installations. Note: the US federal solar tax credit expired December 31, 2025. State and local incentives still vary by region. South African taxpayers can claim accelerated depreciation under SARS section 12B.

Next steps

Use the Solar Panel Sizing Calculator with 4.5 peak sun hours to find out exactly how many panels you need. Then check the Solar Savings Calculator for a 25-year projection using the local $0.17/kWh rate. If net metering is poor in Maryland, also run the Battery ROI Calculator — batteries may be essential rather than optional.
