Maintenance contract on commercial scale installs

[SolarCity]

Does anyone offer maintenance contracts on larger installs?

If so, what kind of services do you provide? Is it an annual visit? How much do you charge?

It seems a little unnecessary to me but some firms seem to like it.

If your customer is interested in this type of thing, it might be worth looking at including an extended warranty as part of your service. Some manufacturers offer a guarantee on the inverter being working (eg) 98% of the warranty period, and will pay lost FIT and maintenance costs if this does not happen, including sending engineers to site etc.

It is expensive, but on large installs can be worth it.
