What is the difference between "low maintenance cost" and "high installation cost"?

. Utilize the renewable sources in best way – Because the batteries are connected to the system to store the energy, there is no waste of the excess energy generated on bright sunny days. So, these systems make use of the renewable energy in best way, storing energy on a good day and utilize the stored power on a bad day. The balance is maintained.

3. Low maintenance cost – The maintenance cost of the hybrid solar energy systems is low as compared to the traditional generators which use diesel as fuel. No fuel is used and they do not require frequent servicing.

4. High efficiency – The hybrid solar energy systems work more efficiently than your traditional generators which waste the fuel under certain conditions. Hybrid solar systems work efficiently in all types of conditions without wasting the fuel.

5. Load management – Unlike traditional generators, which provide high power as soon as they turned on, most of hybrid solar power systems manage load accordingly. A hybrid solar system may have technology that adjusts the energy supply according to the devices they are connected to, whether it’s an air conditioner requiring high power or a fan which requires less.

Like all things, hybrid solar energy systems also have few disadvantages. Let’s have a look at them:

1. Complicated controlling process – With different types of energy sources in use, the systems require some knowledge. The operation of different energy sources, their interaction and co-ordination must be controlled and it can become complicated.

2. High installation cost – Although the maintenance cost is low, the initial investment for the installation of a hybrid solar energy systems is high as compared to a solar systems.

3. Less battery life – The batteries connected to the system may have a lower life as they are often exposed to natural elements like heat, rain, etc.

4. The number of instruments connectable is limited – The number of devices you can connect to a hybrid solar energy system is limited and vary from system to system.

With this advantages and disadvantages, the hybrid solar energy systems are becoming popular around the world and are being installed for homes and offices. So, they are a good consideration
