SOLAR PV SYSTEMS (illustrations)
At INTERCROSS TECHNICAL SERVICES LTD we specialize on below PV Solar solutions
1-OFFGRID SYSTEMS
Typical OFFGRID solar systems are based on the following components:
- solar panels – These take the energy from the sun and turn it into electrical energy, electricity.
- batteries – Since the sun doesn’t always shine, the electrical energy has to be stored somewhere for use in the meantime. We store it in batteries.
- charge controller – This controls charging of the batteries, similar to how as a cell phone charger controls charging of a cell phone.
- service box – This part you should be familiar with since you already have one of these. This is your breaker panel with all your breakers in it for in case there is an electrical short somewhere.
- loads/appliances – Your lights, fridge, fans, clocks, …
- generator – A diesel, propane or natural gas generator for generating power in case there hasn’t been sun for a long time and the batteries are dead. This will provide elecricity when that happens.
- inverter – Takes the power in the batteries and converts it into a form suitable for your loads/appliances. It also takes power from the generator and passes some through to your loads/appliances and uses some to charge the batteries.
2-HYBRID PV SYSTEM
Hybrid solar systems generate power in the same way as a common grid-tie solar system but use special hybrid inverters and batteries to store energy for later use. This ability to store energy enables most hybrid systems to also operate as a backup power supply during a blackout, similar to a UPS system.
Traditionally the term hybrid referred to two generation sources such as wind and solar but in the solar world the term ‘hybrid’ refers to a combination of solar and energy storage which is also connected to the electricity grid.
Typical hybrid solar systems are based on the following additional components:
- Charge Controller.
- Battery Bank.
- DC Disconnect (additional)
- Battery-Based Grid-Tie Inverter.
