See Your Solar Potential in a Few Simple Steps

Every home is different. Your electricity usage, property characteristics, utility provider, and energy goals can all influence your solar options. The calculator uses the information you provide to help create an initial estimate of your solar potential.

Tell Us About Your Home

Provide basic property information so we can better understand your location and potential solar needs.

Share Your Energy Usage

Your electricity usage helps provide a clearer picture of your household energy needs.

Explore Your Solar Estimate

Review your initial estimate and learn what next steps may make sense for your home.

A quick estimate can give you a starting point. A custom solar proposal provides recommendations based on your actual property and energy goals.

What Affects Your Solar Savings?

Your potential solar savings depend on more than the number of panels installed.

Several factors can influence your estimate.

Current Electricity Usage

Your historical electricity consumption helps determine how much energy your household uses and what type of solar system may be appropriate.
Current electricity rates can influence projected solar economics.
Available roof space, orientation, condition, and layout can affect system design and potential solar production.
Trees, nearby buildings, chimneys, and other obstructions may affect how much sunlight reaches your roof.
Utility requirements and applicable policies can influence project planning and estimated outcomes.
The way you choose to go solar can affect upfront costs, monthly payments, ownership, and long-term financial considerations.
Current solar programs may affect project economics when eligibility requirements are met.

Your Estimate Is the Starting Point

An online solar calculator can help you explore your potential, but it is not a substitute for a property-specific solar design.

If you decide to continue, RxSun can review additional details about your home and prepare a custom solar proposal.

Your proposal may include:

01
Recommended System Size
Preliminary Panel Layout
Estimated Energy Production
02
Equipment Recommendations
Financing Options
03
Applicable Program Review
Battery Storage Considerations
This gives you a clearer picture of what solar could look like for your property.
