Why install solar panels?
Installing solar panels lets you generate electricity from sunlight. This can reduce your electricity bill and help lower greenhouse gas emissions associated with fossil fuels.
Solar panels can also provide a reliable source of renewable energy in remote areas where electricity is limited or unavailable.

Cost
The cost of installing solar panels
depends on several factors:
System size
The size of the solar system is an important factor in the total cost. A larger system will require more solar panels and materials.
Geographical location
This can affect the cost because labour and material prices vary between regions.
Efficiency and quality
High-quality, efficient solar panels will cost more than lower-quality ones.
Installation
The installation cost depends on the complexity of the work and the contractor’s experience.
Energy consumption
The home or business’s energy consumption determines the required system size and therefore the total cost.
Additional technology
Energy storage or advanced monitoring systems may increase the cost, but can also improve the system’s efficiency and functionality.

Operating plan for a solar plant
Solar panels + batteries + selling energy to the grid.
- Receiving light. Solar panels receive sunlight. Photovoltaic cells convert this light into electric current through the photovoltaic effect.
- Converting current. The generated current is direct current (DC). The inverter converts it into alternating current (AC), which is used in domestic electrical networks.
- Energy storage. With batteries, some electricity is stored for use at night or during periods of low solar activity.
- Feeding back to the grid. If the system produces more energy than needed, the excess can be sent to the electricity grid (where local regulations allow it).
- Powering the home. The converted, and possibly stored, electricity powers household appliances and systems.
How it works
Operating plan for solar panels
- Sunlight is made up of small particles called photons.
- Photons strike the solar panel and release electrons from silicon atoms inside the cells.
- These now-free electrons create an electric current as they pass through the layers of the solar cell.
- The current flows to the edge of the panel through a conducting cable leading to the inverter.
- The inverter converts direct current (DC) into alternating current (AC), which is used to supply electricity.
- The electricity is transferred to the building. If the panels are connected to the meter, excess power goes to the grid and the meter runs backwards, crediting the surplus generation.
