AES Indiana (formerly IPL) Net Metering & Solar Buyback Rules
In Indianapolis, grid interconnection with AES Indiana (formerly IPL) is governed by municipal and state public utility commission standards:
Indiana Excess Distributed Generation (EDG) inflow/outflow billing.
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.
Dollar-for-dollar income tax deduction on entire turnkey equipment and installation costs.
Indiana statutes protect homeowners from property tax hikes resulting from added solar home value.
Tier 1 monocrystalline panels include 25-year 85%+ linear performance guarantees.
Solar Energy FAQs for Indianapolis, IN
How many solar panels do I need in Indianapolis?
For a typical 1,800 sq ft home in Indianapolis 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 Indianapolis's 4.5 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 Indianapolis 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 AES Indiana (formerly IPL) from the utility grid.
