We have both solar water and solar electric. We've had solar water for 5 years and it paid for itself in the first year. We only fill our propane once a year now instead of every three months. The solar electric we did through STI. We have 2 solar panels connected to a microinverter system that was a fraction of the cost of other systems and it cut our electric bill in half and keeps us well below the DAC and it's easily expandable if our usage should go up. Solar Technology (STI) did an excellent job of instillation and we've never had any issues. Just depend on what your needs are.
