Electricity Rates - Monthly Accounting of Excess Generation

I have just updated to the new version of SAM and the Monthly Accounting of Excess Generation seems to have new options than before (can't remember what they were), but when I toggle between

Option 1 - Cumulative hourly excess credited to current month bill in $ at sell rates ($0/kWh), and

Option 2 - All generation sold at sell rates and all load purchased at buy rates

The results change significantly - from an attractive return and 7yr payback to a negative return and NA payback.

Correct Financial Model for Rental Property

I would like to model a small system 4-6kW where the owner installs the system on a rental property she owns. She does not benefit from or pay the utility bill; her tenant does. Would this be a commercial model? I anticipate she will be eligible for SRECs and a rebate as well as the federal ITC and accelerated depreciation as the system owner. Thanks in advance for your assistance.

New feature "Added return on equity (ROE) input for modeling specific financing scenarios in international locations."

New feature "Added return on equity (ROE) input for modeling specific financing scenarios in international locations." in SAM 2017.1.17

No idea, how it works or what it does.

I introduce values, but the results do not change.

Best regards.

Include Incentives when using Third Party Owner Financial Model

Hello,

I am fairly new to using SAM. I am trying to model a third party owned solar system. The terms of the financial agreement are PPA. I also need to include the ZREC Incentive in the model. However, with the Third Party Owner financial model I do not see a place to include Incentives. The PPA financial model does have Incentives; however, I need the Electricity Rate/Load sections. Is there any way to achieve what I need - PPA term of agreement with the sections for Incentives, Electricity Rate and Electricity Load available? I really appreciate your help with this.

Testing of New "Value of RE" Macro

In preparation for the January 2017 version of SAM, we have developed a test version of a new macro that we hope will be useful for analysis of behind-the-meter applications (Residential and Commercial financial models in SAM) where the value of the electricity generated by the renewable energy system is determined by the reduction of the residential or commercial building's annual electricity bill.

Financial mpdel

Dear all.
In Sri Lanka, for renewable energy, tax free for first 12 years. Also there is a tax on the investment. Is there any facility to enter these kind of data (can we schedule the tax data?)?

Replicating PVWatts economic analysis for cost/financed_kWh

PVWatts offered a valuable solar value estimate to consumers, that was disabled recently. PVWatts presented an "Initial Economic Comparison" that included a "Cost of Electricity Generated by System" estimate(for a financed system) with a "Average Cost of Electricity Purchased from Utility". This was an excellent approach to inform consumers of the solar value proposition, reducing it to a simple kWh commodity comparison.

Demand Data

When entering the energy (kWh) data in the “Normalize supplied load profile to monthly utiliy data”, can I enter the demand (kW) in the same way as I am able to enter the energy (kWh)? Please advise.

Simulation with 10-minute load data

I try to simulate a PV, commercial project with a very specific electric load profile. This load profile is provided in 10 min average values which I’ve copied in the Electric load data through the Edit data in the Energy usage box. I can view this load data and the screen gives correct monthly load summary. However when I try to start the simulation I receive an error message that the electric load profile must have same number of values as weather file, or 8760. How can I solve this problem? Are is it not possible to do sub hourly simulations?

Levelized Cost of Energy (LCOE) Projections

I’m working on a task that is evaluating the costs of future renewable energy projects, and I was hoping you could help me determine some of the default system inputs used in the SAM model. I’m especially curious about the levelized cost of energy for all of the associated technologies that can be chosen in the model.
