Benefits of Having a 1kW Solar System Installed at Home
Solar panels are indeed one of the best ways to ensure self-consumption while cutting down heavily on your energy bills. Additionally, solar panels have a positive impact on the environment. Here are some of the major benefits a homeowner can enjoy with solar.
Accessibility as per your needs:
With three solar model types to choose from, buyers can enjoy greater convenience and advantages. Homeowners can export the extra electricity they produce to the public grid if they choose to install 1 kW on-grid solar panels. When you don’t draw any electricity from the grid due to sufficient solar power generation by your 1kW solar panels, the utility bill will reflect zero charge.
On the other hand, those who want to enjoy independence from government grids and be self-sufficient in producing and storing electricity may go for a hybrid or off-grid system. Off-grid systems even work for locations that do not have access to the local grid!
It is a reliable source of electricity:
Since you will be generating your electricity, you will still have power even when the entire town experiences a power cut. Whether you choose an off-grid system with a battery backup or an on-grid system with accessibility to the local grid, there will always be enough surplus electricity to power your home for hours. In addition, today's photovoltaic solar panels are better-performing in terms of energy output against the sunlight captured.
Therefore, fewer panels are required to produce sufficient solar electricity.
Energy Cost Savings:
For most homeowners, the cost of fuels and monthly bills can be quite overwhelming. Solar systems can help you reduce your energy bills by up to 70%. With solar powering your home, you get to save small amounts every month, which results in higher profitability in the long run.
How many solar panels do I need for 1 kW?
The conversion of one kilowatt (kW) of power requires solar panels with wattage levels for their units in this calculation. Modern residential solar panels generate an output power between 300 and 400 watts in their standard configuration.
Generally speaking, one would need between 3 and 4 solar panels to obtain a total of 1,000 watts (1 kW) in power generation. The power calculation requires 3 solar panels using a wattage of 330 (1,000/330 = 3.03). Your actual power output might vary through different elements that include panel efficiency in addition to sunlight hours and roof orientation as well as shadiness.
The theoretical requirement for 3 to 4 solar panels stands true, but local circumstances may require some modification.
Types of 1kW Home Solar Systems
To cater to the varying electricity needs of customers, there are three different types of solar systems available in India.
On-grid 1kW Solar System (with grid export)
Off-grid 1kW Solar System (with Battery Backup)
Hybrid 1kW Solar System (Solar Battery Storage with Grid Connection)
On-grid kW Solar System
Also known as a grid-tied system, an on-grid solar system allows you to draw electricity from both your solar system and the grid. It consists of only two main components — solar panels and a solar inverter. Since the system lacks a solar battery or similar storage device, it cannot provide power backup. Solar panels generate the electricity, which then flows through the inverter for conversion from DC to AC for household use.
If you generate more electricity than you consume, the utility grid will automatically export the excess power. In this way, you can export extra or unconsumed electricity to the grid and get compensated for it on days when your consumption exceeds generation. On average, a 1 kW on-grid solar system produces about 4–6 units per day, depending on your location.
Here are some key highlights of having on-grid 1-kilowatt solar panels at home:
Since this type of solar system requires fewer components, it is on the affordable side — no recurring costs.
We consume electricity in accordance with our home's power needs.
The grid receives the excess power you generate. Net metering ensures and keeps a record of all units exchanged between you and the grid, which reflects periodically in monthly bills.
The utility grid can be used to draw power in case of less energy generation from the solar system and at times when there is no generation, like at night.
Off-grid kW Solar System
Also known as a solar system with battery backup, off-grid solar systems are designed for places with no access to the grid or when the homeowner wants independence from power outages. This kind of solar system comes with solar batteries and can function effectively independent of the grid connection. The main components include solar PV modules, a solar inverter, a solar battery (normal or lithium-ion), and the balancing equipment (mounting structure, MC4 connectors, DC wire, DCDB box, and earthing kit).
With this system, the unconsumed electricity does not go back to the grid. Instead, solar batteries store it. It is a complete power bank in itself and provides a power backup when your solar panels aren’t producing electricity. On average, a 1kW off-grid solar system generates 4–6 units per day.
Here are some key highlights of having off-grid 1-kilowatt solar panels at home:
It operates without a grid; the battery serves as both a grid and a device for storing power.
When the solar system does not generate electricity due to a lack of sunlight, the system utilizes the stored power to run electrical appliances.
Ensures reliable power supply
Hybrid 1kW Solar System
The hybrid solar system combines the functionality and features of both on-grid solar systems and off-grid solar systems. While a hybrid system stays connected with the conventional utility power grid, it also contains a battery backup. The backup system allows the user to not only export power back to the grid once your battery and appliances are fully charged but also draw from it in times of excess power demand. We recommend this type of solar system for reliable power backup, to eliminate unexpected power cuts, and to lower energy bills.
Here are some key highlights of having a hybrid solar system at home:
Excessive energy can be both stored (in the battery) and exported back (to the grid), resulting in no wastage.
With features like battery backup, its demand stays firm in the market.
