- Does switching to solar save money?
In general, yes — but it depends on a few factors. • Electricity rates in DMV: Utility prices in DC, Maryland, and Virginia are relatively high compared to the national average. This makes solar more cost-effective here than in lower-cost states. • Upfront vs. financing: If a customer buys the system outright, payback is usually 7–12 years. With financing or leasing, savings appear immediately, but long-term savings may be lower depending on contract terms. • Incentives: • Federal solar tax credit (currently 30% off system cost) applies nationwide. • Maryland offers SRECs (Solar Renewable Energy Certificates) that can generate additional income. • DC has one of the strongest SREC markets in the U.S., sometimes making solar very profitable. • Virginia incentives are weaker but still benefit from the federal tax credit. • Property value: Multiple studies show homes with solar panels sell at a premium (4–5% higher on average). • Net metering: In DMV, most utilities allow homeowners to send excess power back to the grid for bill credits, further increasing savings.
👉 Key takeaway for customers: • If they own their roof, have good sunlight exposure, and plan to stay at least 5–10 years, solar usually saves money and adds home value. • If their roof is shaded, or they’re planning to move soon, it may not be as beneficial.

- Types of solar systems
Yes, solar comes in a few main categories: 1. Grid-tied systems (most common in DMV) • Connected to the utility grid. • Excess power is credited (net metering). • No batteries — customers still draw from the grid at night. • Lowest upfront cost, fastest payback. 2. Hybrid / Grid-tied with battery backup • Connected to the grid, but also has batteries (e.g., Tesla Powerwall, Enphase). • Provides backup during outages (big selling point in storm-prone areas). • More expensive upfront, but adds energy independence. 3. Off-grid systems • Standalone, with batteries (and sometimes generators). • Rare in suburban DMV — mostly for cabins or rural properties. • Expensive and usually not needed unless the home is far from power lines. 4. Types of panels (by technology) • Monocrystalline: Most efficient, sleeker black look, higher cost but better in smaller roof areas. • Polycrystalline: Cheaper, bluish color, slightly less efficient. • Thin-film: Lightweight and flexible, but much lower efficiency. Rare in residential installs.
