Off grid solar power system:
It is most common type of solar power system with backup. It works in day and night both, during the day, solar panel charges the battery and runs the home appliances such as Air Conditioners, Cooler, Television and submersible pump. At night, when the sun is not available, Inverter runs your home appliances using the battery power.
Advantage: no dependency on government electricity power
Drawback: expensive than on grid solar power system
What appliances will be running on off grid solar powered system?
In off grid solar powered system, how much power you can run depends upon power of Inverter and it’s efficiency, generally all inverter comes with 80% efficiency, so, if you buy 3 kw Inverter system then up to 2,400 watts of peak power you can run at given point of time. Running air-conditioner and submersible can be expensive for you.
What is latest technology trends in solar inverters?
There are two types of solar inverters, 1) PWM – relatively low efficiency 2) MPPT Based – high efficiency
PWM based – it stands for pulse with modulation, these inverter low on efficiency but prices are very low. For smaller needs, PWM based inverters are recommended for smaller use such as running 3-4 fans, 8-10 lights, 1-2 Television, 1 Refrigerator in day and night.
MPPT Based – it stands for Maximum power point tracking. If your purpose of investment in solar is to save electricity bill, then it is strongly recommended to opt for MPPT based inverters.
Now that we have more renewable source of energy, next only to grid energy, a number of options are available to us when it comes to outdoor LED solar...
