Online State Grid Photovoltaic Panels

Are solar photovoltaic map services free?

Map services and data downloaded from the U.S. Large-Scale Solar Photovoltaic Database are free and in the public domain.

What is a solar photovoltaic Geographic Information System?

It gives the annual output power of solar photovoltaic panels. As a photovoltaic Geographical Information System it proposes a googlemap application that makes it easy to use. The area covered by the calculator is almost the world : America, Europe, Asia and Africa.

What is a photovoltaic (PV) cell?

A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.

How many PV panels are in a PV array?

A PV array can be composed of as few as two PV panels to hundreds of PV panels. The number of PV panels connected in a PV array determines the amount of electricity the array can generate. PV cells generate direct current (DC) electricity. DC electricity can be used to charge batteries that power devices that use DC electricity.

What is a PV inverter?

Devices called inverters are used on PV panels or in PV arrays to convert the DC electricity to AC electricity. PV cells and panels produce the most electricity when they are directly facing the sun.

What kilowatt-peak (kWp) should a pvgis value be?

The peak power should be entered in kilowatt-peak (kWp). PVGIS provides a default value of 14% for overall losses in the solar electricity production system. If you have a good idea that your value will be different (perhaps due to a highly efficient inverter), you can slightly reduce this value.
