Sol-Ark.com 1) 30% Federal Credit + 25% Rural REAP + State Incentives 30% to 55% solar cost is paid Fed & State Incentives going away. Utah = $1600 Why are you waiting?
Sol-Ark.com 2) Look for Battery Based Solar Grid Tied Inverter Meter Inverter

www.portablesolarllc.com Sol-Ark.com 2) Look for Battery Based Solar 99% of installed Systems are Grid Tied AND don t work if the Power Grid fails or Off Grid.
Sol-Ark.com 3) Look for Reduced Electric Bills, not DIY backup Get Grid Interactive, Hybrid, or Multi-Mode System. Reduced energy bills are the biggest way solar systems pay for themselves. Most DIY backup systems only use panels when the Power Grid fails.
Sol-Ark.com 4) Don t Deep Cycle Batteries & they last 10+ years Get Grid Interactive, Hybrid, Multi-Mode System: keep batteries charged. Most DIY systems only switch to Grid when batteries are fully depleted & cycle batteries deep every night = 2-3 years life.
Good systems = 10+ years Most DIY systems = 2 years Sol-Ark.com
5) Good Solar Panels last 50+ Years Sol-Ark.com
