When will solar electric power be added to the options?

Please add ability to upload solar energy generated data, ideally on a time period that the user can define (e.g. daily), and provide access via an API.

Also allowing home to be subdivided, for example I will have 5 separate solar systems soon, and would like to upload data for each automatically each day, if not each minute. If you do this in a flexible way it could simply allow for sub-division of a home with energy generators and consumers (sub-meters). And yes, I have sub-metered devices with real time load data.

See www.ourcoolhouse.com/monitor/monitor.htm for an example of something that would be cool to implement, but with a Microsoft supported API to contribute data.

Solar Photo-Voltaic systems work in conjunction with a "net-meter" that subtracts the PV generated energy from the total used by the house, meaning the kwh value you get from the utility will show only this difference. As other pointed out, you need an independent way to acquire the PV component so that it can be added to the billed kwh.

It would be nice to amortize the out-of-pocket cost for the solar PV system over say a 10-year period so that all energy "cost" is incorporated into the model.

Back to the question of incorporating SolarPV, you should be aware of the standards that are being defined for the SmartGrid to standardize the acquisition and publishing of related home energy metrics. In smart homes, many of the appliances such as water heaters will have individual energy usage measurements, and this information is needed to bring your model into better conformity.

Thanks

In addition to PV I am a Time of Use (TOU) customer, so I pay more during the day (or really make more) and pay less at night than normal consumers. This needs to be accounted for also.,
