As I mentioned previously, I was considering installing a photovoltaic system this year to offset some of our home energy costs. But the PV systems are still quite expensive. Even with net metering, it could take decades for a system to pay for itself, and as the fine folks at Missouri Solar Living pointed out to me, something close to 15% of your home energy costs is your water heater. So a much more economical way to save money is to replace your gas or electric water heater with a solar powered one. So that’s what we’re going to do. I will continue to post updates on this project, so stay tuned.
