Solar Panels for a 1,200 Sq Ft Home

Estimate panels, system size, and savings for your home size

✓ Free, instant, anonymous. No email required.

A 1,200-square-foot home typically uses between 700 and 1,000 kWh of electricity per month, depending on climate zone, insulation quality, and whether you heat with gas or electricity. A solar system sized to that load can cover most or all of your utility bill — and in states with net metering, any excess production earns you credits. We've pre-loaded the numbers for a 1,200 sq ft home so you can see a realistic estimate in seconds.

Solar Panels for 1,200 Sq Ft — FAQ

What are my options for financing solar panels?▾
The main options are: (1) Cash purchase — best ROI, you get the full ITC. (2) Solar loan — low-rate loans from installers, Sungage, GreenSky, or your credit union allow ownership with no upfront cost. You still get the ITC. (3) HELOC — if you have home equity. (4) Solar lease/PPA — no ownership, no ITC, lower savings but zero upfront. (5) PACE financing — property-assessed loans available in some states.
What state incentives are available for solar in addition to the federal ITC?▾
Beyond the 30% federal ITC, many states offer additional incentives: property tax exemptions (most states), sales tax exemptions (many states), cash rebates (e.g., NY-Sun, Colorado RENU), performance payments (SREC markets in NJ, MA, DC, MD, PA, OH), and low-interest loans. Check dsireusa.org for your state's current programs.
What is a good payback period for solar panels?▾
The typical solar payback period in the US ranges from 6 to 12 years. States with high electricity rates (California, Massachusetts, Hawaii) tend to have shorter payback periods. The 30% federal Investment Tax Credit (ITC) can shave 2–3 years off the estimates shown here.
How do I size a solar system to my electricity bill?▾
Divide your monthly bill by your electricity rate to get monthly kWh, then multiply by 12 for annual kWh. Divide annual kWh by (peak sun hours × 365 × 0.80) to get approximate system size in kW. This calculator does all of that automatically — just enter your bill and state.
Can my HOA prevent me from installing solar panels?▾
In most states, no. Over 25 states have solar access laws that limit or prohibit HOA solar restrictions. California, Florida, Texas, Colorado, and New York all have strong protections. Your HOA can still regulate aesthetics (panel placement, color of conduit), but cannot block installation outright. Check your state's laws at dsireusa.org.
