Utility Grid Interconnection

Public Service Company of New Mexico (PNM) Net Metering & Solar Buyback Rules

Under this policy, during peak daylight hours when your solar system generates more power than your home draws, the excess electricity flows back across the grid through a bi-directional smart meter, accumulating dollar or kWh credits directly on your monthly electric bill.

Solar Energy FAQs for Silver City, NM

How many solar panels do I need in Silver City?

For a typical 1,800 sq ft home in Silver City with an electric bill around $180/mo, a system between 6.5 kW and 8.5 kW (approx 17 to 22 400-Watt panels) is required to offset 85% of annual consumption, accounting for Silver City's 5.5 daily peak sun hours.

Do I need home battery backup storage (like Tesla Powerwall)?

While battery storage provides emergency resilience during outages and optimizes peak time-of-use discharge, grid-tied rooftop solar in Silver City can operate smoothly with standard bi-directional net billing without mandatory battery storage.

What happens on cloudy or rainy days?

Solar photovoltaic cells continue generating electricity even under diffuse ultraviolet light (typically 20% to 35% of peak capacity). Any energy deficit is seamlessly supplied by Public Service Company of New Mexico (PNM) from the utility grid.
