Pretty straight forward, put them on as many rooftops as you can regardless of suitability or quality components. Collect government rebate +/- co contribution.

Sometimes it’s that picture of the bill; they use it it switch you to a more expensive energy provider.

Idk. We put in solar 3+ years ago.. We're at roughly 1/3 paid off now. A pay an electric bill 2-4 months of the year. One or two low ($5-80), and one full ($300+), another somewhere in-between ($130-180).

With the information on the bill they can actually sign you up for a different delivery provider or add stuff to your plan.

Some of them will install panels and you won't see money for years if ever without litigation.
