Solar battery buying guide

Hybrid inverters make it possible by adding batteries to your current systems and connecting them to the grid. Battery rebates make batteries cheaper, improving payback. Here are some examples of prices I’d consider reasonable. You can charge them using excess electricity generated from solar panels, or other home generation. As the battery technology evolves, the batteries are getting more compact, power dense, and cheaper. The algorithms can focus on different goals: resilience during power outages, grid balance, reduced energy fees or a maximal use of green energy.

Payback periods and savings

One downside to the batteries is that they do not have backup power functionality.

For example, if you charge a 10kWh battery during the day, that’s a 10kWh less feed in tariff that you will see on your bill. But how long will the battery take to pay for itself, in the form of lower power bills. Cheaper batteries generally have shorter warranties. For example, if you charge a 10kWh battery during the day, that’s a 10kWh less feed in tariff that you will see on your bill. There are two measurements to consider: Storage capacity is how much energy the battery can hold; usable capacity is the energy the battery can provide minus the energy needed to operate the battery. The algorithms can focus on different goals: resilience during power outages, grid balance, reduced energy fees or a maximal use of green energy. So my name’s Tanguy Clarke.
