Providing Reliable and Cost Effective, Backup Power through solar using underutilized rooftops.

Solar Hybrid Solutions is On-grid system with a battery connected to store Power. It combines Solar Modules, AC utility, and battery power source to supply continuous power.

This is suitable in case of situations where a user is using Ongrid systems but facing a lot power cuts during night times. Using a Hybrid Solar PV system comes in handy during these times since there is battery backup to provide power in case of power cuts.

The usual design of a Hybrid Solar PV systems is as follows:

Power generated from the Solar Panels is supplied to the load and in case of surplus power, it is stored in batteries. After the batteries are fully charged any excess power is supplied to the Grid.

Similarly in case of power needed by the load and there is no solar power, if there is grid availability then power is supplied from the grid. In case of no grid power then power is taken from the charged batteries.

The main feature of the Inverter being its ability to feedback the excess generated power to utility grid in case of no usage. This is not possible from a standard Off-Grid system.

Before the design is started the energy load profile is sketched out by taking a look at the electric load of the major appliances used. Energy efficiency can be brought about by choosing the right appliances and efficient home design.

This system boasts of providing rooftop solar solutions with advantages of a Grid-tied and Off grid system. Battery backup can be used to store power.

Frequently Asked Questions(FAQ)

The main reason for getting Hybrid Solar PV system is to keep electricity going even when the grid power goes down.

Yes, you can.  A thing to note is if you want to upgrade the system, it can be very expensive.

Check the system size before retrofitting.

A system size of 5kW is ideal to set up the system with batteries. If the system capacity is less than 5kW consider adding more solar panels with additional inverter capacity to sustain the solar panel addition.

The cost per watt of a Hybrid Solar system is 85Rs per Watt. So a 1KW Solar system costs 85000 rupees. Compared to this the Ongrid Solar system costs around 82 Rs per Watt and and for an Offgrid Solar PV system it cost around 133 Rs per Watt.

LION batteries which are used in consumer electronics are the most preferred batteries for Hybrid Solar PV systems. These batteries  are light and small and provide long lasting life with their deep discharging abilities.

Yes it is worth installing given that the costs of the battery and storage systems are coming down in the recent years.

DC coupled systems :

These kind of systems are used for low voltage DC loads.The Direct current output of the Solar Array is converted to voltage of the the DC appliance. In case of a battery bank it is the charge controller. In case of AC loads its the Solar Inverter or Inverter-Charger that converts DC to Ac power.

AC coupled systems :

In an AC coupled system the PV array is directly connected to a Solar Inverter. The Inverter converts the DC output of the Solar panels to Direct Current which is supplied to the AC loads. The network can be setup to work as an Ongrid Solar system or Hybrid Solar system. A hybrid solar system can utilize a single hybrid solar inverter or  in case of a retrofit installation have an inverter charger in addition to the existing solar inverter.The inverter-charger is employed to charge and discharge the battery storage bank.
