Solar Edge 3D plot

Consumption vs utility room temperature. We have a heat pump water heater, so when it is running the room temperature goes down.

Artisan estimates the energy output of the system verses the month of the year. This estimate feeds into a spreadsheet used to compute the overall costs of the system after rebates, PSE payments, etc. Here's how we're doing so far. The purple line is the actual energy production, the dotted line is Artisan's prorated monthly estimate.

Another way to look at daily variation is by plotting daily power benchmarks: sunrise/sunset, first and last generated power, first and last 1 kW power, and peak power.

System lifetime performance, production vs. consumption

How much power the solar panel system generated over the past few days. Power generation is mostly a function of weather and solar geometry. The Solar Incidence Angle is the angle between a ray perpendicular to the plane of the solar panel and a ray pointing towards the center of the sun. A lower value indicates the sun is more directly centered in front the panel.

Solar Edge Incidence

Solar Edge reports power every 15 minutes. This plot shows theoretical best, worst, and average days by analyzing this 15 minute data:

Total energy production by day by rising/setting

Throughout the year the system generates energy, more in the summer and less in the winter. You want the summer surplus to more or less balance out the winter deficit, breaking even over the course of a year. This plot shows total production, total usage, and current energy balance for the year.

Some days are better than others due to cloud cover and solar geometry. Here are the best and worst days so far.

Year over year consumption and solar production, 14 day trailing average

SSH break-in attempts on various servers, 7 day trailing average
