Solar Storage - 2023 Update
A few years back I published a 2 Part post discussing Solar Energy systems. The discussion focused on all the due diligence and prep work needed and what were some of the key considerations around designing and implementing a solar system. One of the discussion points was around solar storage or batteries. What were the use cases for batteries and if they were a good investment and should you incorporate them into your design. Back in 2020 - the math around batteries said no - that you wouldn't be able to break even on the cost of a storage system over its normal warranty life of 10 years. So here we are three years later and so I figured it was time to revisit. There are two primary uses cases for solar storage. First is what's called peak offset or peak shifting. This is a concept where you utilize stored solar generation to run your home during what many utilities call Peak Periods that are part of a general category of rate plans known as Time of Day (TOD) plans.
