Solar vs. Electric: Which Saves You More in 2025

As electricity prices continue to rise—up 6.2% from 2022 to 2023—homeowners are weighing the benefits of solar energy systems against traditional electric grid reliance. With the 30% Federal Solar Tax Credit set to expire for residential installations on December 31, 2025, and solar panel costs at historic lows, 2025 is a pivotal year to evaluate whether solar power or grid electricity offers greater savings. This guide compares the costs, savings, and long-term benefits of solar vs. electric to help you decide which is best for your home and budget.

Solar Panel Costs vs. Electric Utility Bills in 2025

To determine which option saves more, let’s break down the costs of solar energy systems and grid electricity for an average U.S. household using 10,632 kWh per year (888 kWh/month).

Solar Panel Costs

  • Upfront Cost: A 7.2 kW residential solar panel system (suitable for an average household) costs $18,144–$26,424 ($2.52–$3.67/W) before incentives, based on 2025 EnergySage data. This includes panels, inverters, mounting, labor, and permitting.
  • Federal Solar Tax Credit: The 30% Residential Clean Energy Credit reduces costs by $5,443–$7,927, bringing the net cost to $12,701–$18,497. The credit applies to systems installed by December 31, 2025, and requires filing IRS Form 5695.
  • Additional Incentives: State rebates, tax exemptions, or net metering (e.g., California’s SGIP battery rebates or New York’s 25% tax credit) can cut costs further, sometimes by 10–20%.
  • Battery Storage (Optional): Adding a 10 kWh battery (e.g., Tesla Powerwall) costs $7,000–$18,000 but qualifies for the tax credit, enhancing savings under time-of-use rates.

Electric Utility Costs

  • Average Electricity Rates: In 2025, the average U.S. electricity rate is $0.172/kWh, per the U.S. Energy Information Administration (EIA). For 10,632 kWh/year, this equals $1,829 annually ($152/month).
  • State Variations: Rates vary widely, from $0.11/kWh in Idaho to $0.33/kWh in California. High-rate states like California ($3,516/year) or Hawaii ($4,752/year) make solar more attractive.
  • Rate Increases: Electricity prices rose 6.2% from 2022–2023 and are projected to increase 2–4% annually through 2025, driven by grid maintenance and fuel costs.

Cost Comparison Example

For a 7.2 kW solar system costing $22,000 (mid-range):

  • After Tax Credit: $15,400 net cost.
  • Annual Savings: In California ($0.33/kWh), a 7.2 kW system generates ~10,800 kWh/year, saving $3,564 annually (100% offset). In Idaho ($0.11/kWh), savings are $1,188/year.
  • Payback Period: 4–6 years in high-rate states (CA, NY); 8–12 years in low-rate states (ID, AL).
  • Lifetime Savings: Over 25 years, solar saves $31,000–$100,000, depending on state and rates, minus maintenance (~$300–$600 every 5–10 years).

Grid electricity costs $1,829–$4,752 annually with no upfront investment but offers no long-term savings or tax benefits. Solar requires upfront costs but delivers significant savings over time, especially with incentives.

Key Factors Influencing Solar vs. Electric Savings

Several factors determine whether solar energy savings outweigh grid electricity costs:

  1. Electricity Rates: High-rate states (e.g., CA: $0.33/kWh, NY: $0.24/kWh) yield faster solar paybacks (4–7 years) compared to low-rate states (e.g., ID: $0.11/kWh, 8–12 years).
  2. Sunlight Exposure: Sunny states like Arizona or Texas generate more solar energy per kW (1,500 kWh/kW/year), reducing the system size needed and boosting savings. Northern states like Maine (1,200 kWh/kW/year) need larger systems, increasing costs.
  3. Incentives: The Federal Solar Tax Credit (30% until 2025) and state programs (e.g., New Jersey’s SuSI: $85/1,000 kWh for 15 years) lower solar costs. Check the Database of State Incentives for Renewables & Efficiency (DSIRE) for local rebates.
  4. Net Metering: Many states offer net metering, crediting excess solar energy at retail rates (e.g., 1:1 in Arizona). This maximizes savings by offsetting night-time usage.
  5. System Ownership: Owning your system (cash or loan) qualifies you for tax credits and maximizes savings. Leasing or PPAs reduces upfront costs but forfeits tax benefits and may have higher lifetime costs.

Benefits of Solar Over Electric in 2025

Switching to solar energy systems offers several advantages over relying solely on grid electricity:

  • Cost Savings: Solar can save $1,000–$4,000 annually on electricity bills, with lifetime savings of $31,000–$100,000 over 25 years, per EnergySage.
  • Federal Solar Tax Credit: Saves 30% on installation costs (e.g., $6,600 on a $22,000 system) if installed by December 31, 2025. This credit expires in 2026 for residential systems due to the “One Big Beautiful Bill” (OBBB).
  • Increased Home Value: Homes with solar panels sell for 4–6.8% more, adding $15,000–$30,000 for a $400,000 home.
  • Energy Independence: Solar reduces reliance on rising utility rates and protects against outages with solar battery storage.
  • Environmental Impact: Solar cuts your carbon footprint by ~8,000 lbs of CO2 annually, equivalent to planting 120 trees.

Grid electricity offers convenience and no upfront costs but leaves you vulnerable to rate hikes (2–4% annually) and provides no tax benefits or home value boost.

When Is Grid Electricity Cheaper?

Grid electricity may be more cost-effective in specific cases:

  • Low Electricity Rates: In states like Idaho ($0.11/kWh) or Louisiana ($0.12/kWh), solar payback periods stretch to 10–15 years, making grid power cheaper short-term.
  • Unsuitable Roofs: Shaded, north-facing, or complex roofs (e.g., steep, tiled) increase installation costs by $500–$2,000, delaying savings.
  • Low Energy Usage: Households using <6,000 kWh/year need smaller systems (4–5 kW), but lower savings ($600–$800/year) extend payback periods.
  • Short-Term Residency: If you plan to move within 5–7 years, you may not recoup solar’s upfront costs.
