How does a solar panel work?
Particles or photons of light are knocking electrons free from the atoms. This creates a flow of electricity. A solar panels is made up of those cells that are linked together.
The electricity than flow intro a conductive wire on the edge of the panel. When the electricity goes to an inverter it is transformed form DC to AC. That is when we can use the electricity like we always do. To turn on a light for example.
Solar powered heliport

Heliports are through their nature of use great to work solely on solar power without being connected to the grid. Privat heliports will be used mostly once or twice a day and probably not every day. Busy heliports such as for emergency, ambulance helicopters, can be used on a daily basis.

The active periods of these heliports are short. Power consumption therefore is limited and be easily be maintained by solar panels and batteries. Even in higher latitude areas you can guarantee your independent power supply throughout the year by choosing more or larger solar panels or increase the battery capacity.

Advantages, low voltage DC power supply to the heliports lights, very flat perimeter lights, no extensive grid cabling, decreasing CO2 emitting to zero, free electricity and Independent power supply.

The HA-PL5 solar

The HA-PL5 is a portable rechargeable airfield light that is easy to use. The HA PL5 is rechargeable with a solar panel (10W or 15W). When an external charger is used to charge the PL5 it takes less than 8 hours to fully charge the light.

The HA-PL5 solar is a light that does not need to be charged on the net. It charges with the solar panel. (10W or 15W). The HA-PL5 is standard manually controlled, but it is also available in a radio controlled (PAL), LORA/IOT controlled or in stealth option. This makes the PL5 solar great for a solar powered heliport.

The HA PAL (portable aviation lighting) is manufactured according to the following standards. CAO Annex 14 Vol. I, ICAO Annex 14 Vol. II Heliports, FAA AC150/5345-50, UK CAA CAP 168, NATO Stanag.

The PL5 has completed the following test: jet Blast test >400 km/h (>250 mph), impact test, drop tests (0,7-1,00 and 2,00m height), battery endurance, light output, climatic conditions, electromagnetic Compatibility tests.
