Photovoltaic Pannels enables the production of electricity with the sun. This is the main technology to support decentralised energy production from home.

Product components:
| Roles | Definitions |
| Photovoltaic (PV) / Solar Array | This is the energy generator. A photovoltaic (PV) module is a packaged, connect assembly of typically 6×10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity (Wikipedia description). |
| DC | Direct current (DC) is the unidirectional flow of electric charge which is used mostly for power generator or batteries. |
| AC | Alternating current (AC), is an electric current which periodically reverses direction, whereas direct current (DC, also dc) flows only in one direction (Wikipedia description). AC is generally used for home appliances. |
| DC to AC Inverter | Inverter to enable produced PV energy in DC to be transformed in AC. |
| Electric Panel | Electric Panel of the PV place is the operating board to manage the electricity produced form the PV and manage it with the home demand for home appliances and to the utility power grid for the export and import of energy. |
| Bi-Directional Utility Meter | This is the meter managing the export and import of energy to the grid. This bi-directional meter is here to calculate the quantity used and sold (import and export). |
| Home Appliances | All Home appliances which do work with electricity. |
| Utility Grid | The grid is the electrical network used to deliver electricity from energy distributor to consumers. In this picture the network is used to import and export energy. |
Challenges:
– Price of the installation (Return on Invest length)
– Efficiency of the Photovoltaic panels
Success factors:
– Solar panels price reduction
– Energy price increase
– Government support with purchase subside or tax reduction
– Positive sales evolution of EV
