Here is a look at solar metering and the advances that have been made. The latest has allowed for net-metering in shared spaces. This means anything from apartments to shared commercial spaces can make use of locally generated power with greater convenience and accuracy when it comes to billing. This is only going to accelerate the value of solar in commercial spaces since it makes for an even stronger use case.
Here is an excerpt:
A virtual net-metering revolution has quietly occurred in a number of places around the world, including California in the US. California’s version of virtual net-metering allows Californians living in a multi-dwelling building, such as an apartment complex, to have a shared solar system with a percentage of output from each interval (30 minutes is the standard for Australian smart meters) being allocated to each of the owners of the solar system. So if there were 10 residents in an apartment complex who owned a shared solar system on the roof generating 10kWh at midday, each customer would get 1kWh of power over one hour (two intervals), which would offset any of their usage during that period. If they didn’t use any power then their 1kWh would be exported and they’d be paid the same as any other SOLAR PV owner.
But there’s no reason to restrict virtual net-metering to solar systems directly on the roof of an apartment complex you live in, as per the Californian example. Any renewable energy generator (such as a PV SYSTEM) located anywhere (including locations apart from where owners live) should be able to be virtual net metered by a part-owner of the system. (This should extend across multiple distribution areas).
Shopping centre owners could lease their roofspace to people who want to buy into solar generation, landlords could build oversized systems and allocate a portion to their tenant to cover most of their tenant’s daytime use and allocate the rest for themselves to be netted out against their own house’s use (which may not have SOLAR PANELS).
