When does the solar you already have actually pay for itself?
Tell us about the system you already have, how you paid for it, and your current electricity plan. This app will show you your estimated payback timeline based on your actual production, not a hypothetical new system, and tell you whether a different real plan would get you there faster.
Property
Your existing system
Your real, installed system size. Check your installer's paperwork or your inverter/monitoring app if you're not sure.
Household usage
What you actually pay now, solar included.
From a recent bill or your utility's usage history, if you know it.
Your current plan
Your current plan's real buyback rate and base fee matter for every month of this comparison. Without them, this app has to fall back to its own placeholder average, which may not be close to what you're actually paid for exported power. Upload your provider's EFL and this app will pull your real numbers automatically, or skip the upload and type them in below, free, any time.
Your plan's own energy rate only, not your EFL's blended 'average price per kWh.' Delivery charges are added automatically below. Entering an already-blended number counts them twice.
What you're paid for energy you export. Check your EFL's 'net metering' or 'solar buyback' line.
Your plan's own flat monthly charge (not the utility's separate delivery fee, which is added automatically).
Enter your address, system size, and household usage to continue.
