How can on-site solar PV & energy storage improve sustainability?

To achieve sustainability goals while meeting the increasing electricity demands of electrification, organizations are pairing on-site solar PV generation with on-site energy storage. These systems, which are considered as “behind-the-meter” (BTM) systems, allow facilities to maximize the benefits of on-site renewable generation.

What are the benefits of an on-site solar PV system?

For the scenario represented in the graph, an on-site solar PV system allows the facility to reduce the amount of electricity drawn from the grid during the middle of the day. Increasing the amount of solar PV production on-site can provide additional cost and emission reductions and resiliency benefits for facilities.

Should solar PV production be reduced on-site?

Increasing the amount of solar PV production on-site can provide additional cost and emission reductions and resiliency benefits for facilities. However, the additional generation that can result from larger systems during peak daylight hours must be exported or managed through curtailment on-site.

How does a tilt angle affect solar energy production?

The tilt angle directly influences how much solar radiation your photovoltaic panels capture throughout the year. Panels positioned perpendicular to the sun's rays absorb maximum energy, but the sun's position changes with seasons and your geographic location. Poor tilt angle calculation can reduce electrical production by 10-30%.

What is a good tilt angle for a solar panel?

Latitude-Based Tilt: A general rule is to set the panel's tilt angle equal to the location's latitude. For instance, at 30 degrees latitude, an optimal tilt would be around 30 degrees. Seasonal Adjustments: A steeper tilt in winter captures more low-angle sunlight, while a flatter tilt in summer maximizes exposure to direct overhead sunlight.

Does tilt angle affect the performance of PV panels?

Research has shown that the optimal tilt angle for a PV panel varies depending on factors such as geographical location, season, and application. This study aims to investigate the effect of tilt angle on the performance of PV panels in order to optimize energy production.

How does sunlight affect a photovoltaic panel?

This is because sunlight striking the panel perpendicularly is concentrated, maximizing the energy captured by the photovoltaic cells. When the sun's rays hit the panel at an angle, the same amount of sunlight is spread over a larger area, reducing the energy absorbed. The sun's path across the sky depends on where you live.
