Convert energy

Converting energy to electrical energy has become more and more efficient since the discovery of electricity. Optimizing this energy conversion is a continuous process. We give a number of examples of this trend based on a solar panel installation.

Solar cells
For this we start with the solar panels on your roof, the solar cells have become increasingly better in recent years, in 1953 4.5% of the incident solar energy was converted into electricity, the most advanced silicon cells currently have an efficiency. of 26%. Large steps to 40% are expected by applying other basic materials for the solar cells.

Solar panels supply their energy by means of a direct voltage, where in most cases we want the energy to be supplied back to our 230V alternating voltage network in order, for example, to run the washing machine. For this conversion an inverter is used that not only ensures the conversion from direct to alternating voltage, but also that the maximum amount of energy is obtained from the solar panels. All this takes place with high efficiency so that the carefully generated energy is not lost and also not produced unnecessary heat.

The energy generated will also have to be used efficiently. Developments in this area are ongoing, including legislation. Very visible here is the transition from incandescent to LED lamps. Less visible are the rules that apply to standby consumption or the requirements imposed on motors in, for example, roof fans.

Energy storage
If the energy cannot be delivered directly to your washing machine or coffee machine, it will be returned to the electricity grid as standard. Another option is to store the energy locally in a hot water boiler or batteries.

The role of Betronic
Betronic has experience with all of the above aspects that have to do with the conversion of energy. Several projects with inverters for solar panels and wind turbines have been successfully completed. But also projects for energy storage in boilers and batteries, such as the Practical example of EST Floattech.
