Solar energy monthly power generation record form

How is the generation estimate based on data collected for PV solar resources?

The generation estimate is based on data collected for PV solar capacity. Capacity of PV solar resources is collected directly from respondents. These data are collected on several EIA forms and from several types of respondents. Monthly data for net-metered PV solar capacity is reported on the Form EIA-826.

What is monthly generation from small scale PV solar resources?

Monthly generation from small scale PV solar resources is an estimation of the generation produced from PV solar resources and not the results of a data collection effort for generation directly, with the exception of “Third Party Owned” or (TPO) solar installations which has direct data collection. TPO data however is not comprehensive.

Which generators are excluded from the annual electric generator report?

Capacity from facilities with a total generator nameplate capacity less than 1 MW are excluded from this report. Sources: U.S. Energy Information Administration, Form EIA-860, 'Annual Electric Generator Report' and Form EIA-860M, 'Monthly Update to the Annual Electric Generator Report.'

How is net-metered PV solar capacity reported?

Monthly data for net-metered PV solar capacity is reported on the Form EIA-826. Form EIA-826 is a cutoff sample drawn from the annual survey Form EIA- 861 which collects this data from all respondents. Using data from both of these surveys we have a regression model to impute for the non-sampled monthly capacity.

How many kWh do solar panels generate a year?

We will also calculate how many kWh per year do solar panels generate and how much does that save you on electricity. Example: 300W solar panels in San Francisco, California, get an average of 5.4 peak sun hours per day. That means it will produce 0.3kW × 5.4h/day × 0.75 = 1.215 kWh per day. That’s about 444 kWh per year.

Where do solar and wind power data come from?

All national and state-level data come from the U.S. Energy Information Administration (EIA). Utility-scale solar and wind summer capacity values for 2014-2022 are as reported in EIA’s Historical State Data for each year.
