The Growing Popularity of Clean Electricity

Clean electricity is the future, and its demand is increasing rapidly. Many businesses and homeowners are now considering solar energy as an alternative to traditional degradable source of power due to its long-term cost savings and climate benefits.

Why is the World Considering Hybrid Solar Power Systems?

A hybrid solar system uses solar panels to generate electricity from sunlight (photons). The power produced is first stored in a battery and then converted into usable electricity, and surplus generated electricity is fed back to the grid.

The solar PV cell captures photon light and converts it into DC power. This DC output is then stored in a battery or sent to an inverter, which converts it into AC power for household or commercial use. If battery storage is full and additional power is generated, it can be sent to the grid or used to power extra loads.

Understanding the Hybrid Solar System

What is a Hybrid Solar System?

A hybrid solar system combines the stretegy of both on-grid and off-grid systems. It allows homeowners to use solar energy during the day, store excess power in batteries for backup power, and then convert it into usable electricity, and even send surplus power to the grid.

This system ensures a continuous power supply even during electricity outages or at night when solar panels are not generating electricity.

How a Hybrid Solar Power System Works

A hybrid solar power system combines the strategic features of both on-grid and off-grid systems. It uses solar panels, battery storage, and grid connectivity to provide uninterrupted electricity. It allows consumer to store excess solar energy for later use in battery storage and also draw power from the grid when needed.

Step-by-Step Working Process

Solar Power Generation
  • Solar panels absorb sunlight (photon energy) and convert it into DC.

  • This DC power is then sent to the inverter for conversion into AC electricity, which powers household appliances.

Energy Storage in Batteries
  • If the solar pv panels produce more electricity than needed, the excess generated energy is stored in batteries instead of being sent to the grid.

  • These batteries act as a backup for nighttime use or during power outages.

Grid Connection for Additional Support
  • When battery storage is low or depleted, the system automatically switches to the grid to supply electricity.

  • If the solar panels produce excess energy, it can be sent to the grid through net metering, reducing electricity bills.

Automatic Energy Management
  • The hybrid inverter manages power flow between solar panels, batteries, and the grid based on energy demand.

  • It ensures efficient energy distribution, prioritizing solar and battery power before drawing electricity from the grid.

Reliable Backup Power During Outages

The automatic backup system links essential appliances to battery storage during a blackout to offer continuous power supply.

The hybrid solar power system regulates solar energy together with battery storage and grid power connections to maintain both reliable power delivery and affordable energy costs. The system allows customers to break free from the grid and maintain energy flow in cases of electricity grid failures.

How a Hybrid Solar System Works Throughout the Day

  1. Morning:

    • Energy demand is high.

    • Solar production is low, so power comes from the battery (if charged) or the grid.

  2. Midday:

    • Solar panels generate maximum power as the sun is at its peak.

    • Low energy consumption allows excess solar energy to charge the battery and avoid drawing expensive grid power.

  3. Afternoon:

    • Energy demand is still low, and solar production continues.

    • If the battery is fully charged, surplus power is exported to the grid.

  4. Evening:

    • Energy demand spikes as people return home.

    • Instead of buying expensive grid power, the home uses stored battery energy to meet high demand.

  5. Nighttime:

    • The battery continues to supply power.

    • If the battery runs low, grid power is used. However, The battery receives electric charge from off-peak grid electricity when rates in the area are minimal.

    • The hybrid solar system automatically controls a sequence between solar power and battery and grid power to maximize energy management and reduce costs.

Advantages of a Hybrid Solar System

Multiple advantages become available to users when they deploy hybrid solar power systems. The system serves as a backup power source during blackout events. The solar battery system will provide electricity from storage before connecting to the power grid. The system delivers continuous power throughout every period. Solar power systems create reduced dependency on fossil energy as well as reducing carbon discharge.

Steps to Consider Before Installing a Hybrid Solar Power System

  1. System size

  2. Number of panels required

  3. Inverter and battery requirements

  4. Net metering in hybrid systems

  5. Estimated cost of the system

1. System Size Calculation

Different methods are used to determine the required system size based on total power consumption. These methods include:

  • Calculating system size using sanctioned load

  • Based on monthly electricity consumption (units per month)

  • Using the available rooftop area (square feet of the building or house)

Calculate System Size Through Sanctioned Load

The sanctioned load is on your electricity bill. Multiply the sanctioned load by 1.5 to determine the total system size.

Example:

To obtain the total system size of 4.26 kW, users need to apply a 1.5 multiplier to the sanctioned load of 2.84 kW. Future power demand growth requires the installation of a 5 kW system even though the current system could be sufficient with a 4.26 kW capacity.

The total system size can be determined by multiplying the sanctioned load by 1.5.

The measurement of system size begins by evaluating the electricity bill units.

Example:

To get daily power consumption from 500 yearly units, perform 500 / 30.

500 ÷ 30 = 16.6 kWh/day ÷ 5 hours of sunshine = 3.33 kW (~4 kW system size)

Calculate System Size Based on Rooftop Area

If your rooftop area is 50 × 20 = 1000 sq.feet, multiply this by the panel dimensions (length × width) to estimate the number of panels required.

Example:

If the panel is 7 ft × 3 ft = 21 sq. feet, then:

1000 ÷ 21 = 47 panels required

If each panel has a power rating of 480W, then:

480 × 47 = 18.8 kW (~19 kW system size)

2. Number of Panels Needed

To determine the number of panels, divide the total system size by the per-panel wattage.

Example:

For a 10 kW system using 580W panels:

10,000W ÷ 580W = 17.2 panels (rounded to 17)

3. Inverter and Battery Requirements for Hybrid Systems

A hybrid inverter is required to manage both solar energy conversion and battery storage. The inverter size should be 30% larger than the total system size.

If your system is 5 kW, the inverter should be at least 5 kW or more significant.

Battery Storage

Battery size depends on power backup needs. A larger battery capacity is needed for nighttime or emergency backup power.

4. Net Metering in Hybrid Systems

Net metering allows homeowners to send excess power to the grid and receive credits on their electricity bills.

  • If battery storage is full and additional power is generated, it is sent to the grid.

  • If the grid supply is unavailable, the battery automatically powers the load.

  • The unit ratio is 1:1, meaning if 1 unit is sent to the grid, 1 unit can be used later without extra charges.

5. Estimated Cost of a Hybrid Solar System

The total cost depends on:

- PV system structure (galvanized or elevated structure)

- Inverter brand & warranty (different brands have varying prices)

- Battery storage capacity (higher capacity batteries increase costs)

- Wiring and AC/DC earthing materials

- Net metering setup costs
