How Post Falls Electricity Rates Affect Solar Savings
Your electricity rate is the single most important factor in determining how quickly solar panels pay for themselves. At 10.0 cents/kWh, every kilowatt-hour your solar system generates directly offsets energy you would otherwise purchase from your utility provider.

Installing solar now locks in your energy costs for 25+ years, protecting you from future rate increases while benefiting from available state incentives.
Idaho's net metering policy is another advantage for Post Falls homeowners. When your solar system produces more energy than you use, the excess is sent back to the grid and you receive credits on your electric bill. During peak production months, these credits can offset your costs during lower-production periods, effectively reducing your annual electricity bill to near zero.
