These systems use both wind and solar resources in a complementary way, perfect for sunny and ventilated places.
It is a very compact and cost-effective solution, that incorporate the advantages of both the energy production system.
The main advantages are:
- Night and day optimized production;
- Seasonal optimized production;
- Greater system reliability.
Can be provided complete systems as follow:
- On-grid system, were the produced energy is fed into the network;
- Off-grid system, were the produced energy is stored in a battery bank (excessive one dissipate in a dump load), then used to feed isolate users through a dedicated invertor.
