Solar energy
Solar energy is the energy obtained from solar radiation and converted into electricity using photovoltaic panels or into heat using solar collectors.
Principle of operation of photovoltaic panels:
- Solar light falls on photovoltaic panels
- Photons of light knock electrons out of silicon atoms
- Electrons move through the p-n junction
- A constant electric current is created
- Inverter converts DC to AC
Advantages of solar energy:
- An inexhaustible energy source
- Environmental Cleanliness
- System Modularity
- Long service life (25+ years)
- Minimum maintenance

Frequently asked questions
How do solar panels work?
Photovoltaic panels convert sunlight into electricity through the photoelectric effect. Solar rays eject electrons from silicon atoms, creating an electric current.
How much energy does a solar panel produce?
1 kW of solar panels in Ukraine produces approximately 1000-1200 kWh of energy per year, depending on the region and orientation of the panels.
Do panels work in cloudy weather?
Yes, but with lower efficiency. In cloudy weather, efficiency drops by 50-80%, but panels still produce energy.
How long do solar panels last?
Modern solar panels have a warranty of 25 years and can operate for 30-40 years. Efficiency decreases by about 0.5% per year.
