What is a Hybrid Solar System?
Basically, there are 3 types of solar power systems namely, grid-tied (on-grid), off-grid (standalone), and hybrid solar power systems.
- A grid-tied solar system is connected to the utility grid but is not backed by a battery.
- Off-grid or standalone solar power system just have batteries and is not connected to the utility grid.
The hybrid solar power system is a mix of the above two systems. A solar power system with dual connection is particularly termed as a hybrid solar system in which solar inverter is connected to the utility grid and has battery backup too. Solar energy absorbed by solar panels is transferred to a solar inverter which is then supplied to the utility grid and then to the connected loads. Also, from solar panels, the DC power gets stored in solar batteries. And the excess power is generated after being supplied to the house and the battery is fully charged, in that case, this excess energy is fed into the utility grid which gets converted into credits.
A hybrid solar system is advantageous because it gives you a constant power supply irrespective of bad weather or power outage. In case of either problem, a substitute power supply is used. For example, on cloudy days when there is insufficient power generation from solar power systems, you will get the required supply from the utility grid. The units fed into the grid generated credits and those are utilized in these times.
On the other hand, in case of a power outage, your solar panels will power the house and devices during the day, and with battery backup, you can have an uninterrupted power supply at night too. Hybrid solar power systems come in different wattages that define the number of panels, power supplied, and other specifications of the system. Come find out about the 5 kW hybrid solar power system.
What is a 5kw Hybrid Solar System?
Hybrid is the most efficient solar power system with a dual power supply, which is why we consider it a self-sustainable system. Power requirements for homes, small offices, and shops can be met with a 5 kW hybrid solar power system as it can easily operate multiple home and kitchen appliances up to a certain wattage.
1. Working and Important Statistics of a 5 kW Hybrid Solar Power System
1) Power Generation
A hybrid system also works in the same manner as that of others in terms of solar power generation. Solar panels generate direct current after photons from the sunlight are absorbed. Through substrings, power generated by solar panels is collectively transferred to solar inverters.
2) Power Conversion
DC power in the inverter is converted into alternating current (AC) which powers the devices and appliances. In hybrid solar power systems, AC power is transferred to a connected grid which then supplies the required amount to power appliances and saves the remaining. This grid-fed power gets converted into credits which are used when there is insufficient power generation by solar panels and the solar battery does not have enough power backup. The utility grid supplies power to appliances and power used after credits are exhausted is included in your utility bill towards the end of the month.
3) Charging the Battery
DC power from solar panels is also transferred to solar batteries to charge them, in case it is DC coupled. If the battery is AC coupled, then it will be charged from the AC power supplied by the inverter. This power is stored in a battery until and unless required. If there is no power supply from the utility grid, and probably it is nighttime when no solar power generation takes place. Then, power from solar batteries is used to power devices and appliances.

4) Power Monitoring
Solar hybrid inverters in a 5kw hybrid solar system are equipped with solar power monitoring software measuring and monitoring the PV system through mobile linked application and display screen.
5) Power Maximization
Solar inverters with MPPT (Maximum Power Point Trackers) monitor solar power production and regulate its voltage before it enters the battery. With this, the system generates maximum power, and conversion of DC is done at the optimum voltage for charging the battery up to the best level and with the right voltage. MPPT ensures the efficient functioning of solar systems under different conditions like variable solar light levels, solar panel temperatures, and electric loads. After this, let’s learn about the specifications of 5kW hybrid.
What are the Specifications of 5kw Hybrid System?
The specifications of 5kW hybrid system are as follows-
1. Area Required
The standard dimension of residential solar panels is around 2 m by 1 m, and this will take around 30 square meters of area on your roof. With high-efficiency panels, the number of panels required reduces covering less rooftop area.
2. Energy Output
A 5 kW hybrid solar system generates 20 units on average per day. That means in 30 days it generates 600 units and, in a year, it is around 7,200 units.
3. Number of Solar Panels
Here I am referring to polycrystalline solar panels since they are mostly used for small-scale solar power systems. So, with this, you will need around 15 panels, and each panel with 330Wp. With high-efficiency panels, the number of panels required decreases. Also, if you want to know how many panels you require for a particular capacity, divide the total capacity by the efficiency of 1 solar panel. But before that convert kW to MW, for example, 5000 MW (5 kW)/330Wp (watt of one solar panel) = 15.15. Round it and you get 15 panels.
You can reduce the initial installation costs of 5 kW solar power systems by applying for governmental subsidies. Different regions and countries have different facilities for this. Consult with a local installer and proceed accordingly.
Note: The amount and type of government subsidy are subject to change. The percentage of subsidy depends on your location and the rules prevailing in your region.
