Solar cells are also known as photovoltaic cells (PV), which work to generate electricity directly from sunlight. This is different to photovoltaic thermal cells (PVT), which work to provide heat for water in the home. #mppt solar charge controller rs485 Photovoltaic cells are connected electrically, and neatly organised into a large frame that is known as a solar panel. The actual solar cells are made of silicon semiconductors that absorb sunlight and then convert it into electricity.

Currently, solar panels that are used for domestic purposes are only able to take around 20% of the sunlight that they receive and turn it into electricity. This is what is known as solar efficiency. There are several other forms of solar cell available that are used for commercial and industrial purposes. These are able to have an efficiency rating of up to 40%, but they do tend to be more expensive than domestic models.

One of the great things about solar technology is the fact that advances in the field are constantly being made, raising the overall quality and efficiency. #solar charge mppt controller It is expected that this will only increase with further research and development. Similarly, as these aspects increase, the price of solar panels is expected to keep falling – making them available to a much wider number of people.
