What is a Solar Water Heater? A Detailed Overview
48 browse
Solar energy systems are in great demand these days. With the continuous surge in electricity bills each month, people are looking for a reliable yet affordable option for power supply.
With solar panels installed in your residential or commercial area, you can save a lot of money on electricity bills and power your property with an uninterrupted power supply.
This article covers all the details a customer needs about a 3kW solar power system. Although solar power systems come with a specific capacity, 3kW solar power is best for residential use with low electricity demand. And solar panels are ideal for generating your own electricity at minimal cost.
Typically, solar systems come in three types: on-grid, off-grid, and hybrid. The details are as follows;
On-grid solar systems are connected with the utility directly and transfer excess generated power to the utility through net metering. There are no batteries used in an on-grid system. Thus, with an on-grid system, the consumers rely on grid electricity at night. Moreover, since on-grid solar systems do not use batteries, there would be no power backup in case of a blackout or load shedding during the night.
Off-grid solar systems use batteries to store excess energy produced by PV cells. The batteries store enough electricity that consumers can utilize during the night. Moreover, the batteries also provide backup for blackout or load shedding. There is no net metering available for off-grid solar systems.
A hybrid solar system uses both; a grid and batteries. It combines on-grid and off-grid solar systems connected to the utility and has its own battery. In a hybrid solar system, specific battery storage is set. Once the battery is charged, the excess energy is transferred to the electricity grid. Net metering is also available for hybrid solar panels.
A 3kW solar panel is ideal for homes, small companies, and shops. Typically, a 3kW capacity solar system can generate about 2500kWh per year, enough to power a 2-bed house that roughly consumes 300 to 350 monthly units.
Typically, a 3kW solar panel can run at once;
2 LED Lights
1 LED Television
1 Microwave
1 AC Inverter (under 1 tonne)
1 Wifi Router
1 Washing Machine
As a 3kW solar system can generate 10 to 12 units (12000 kWh) per day, it can power home appliances that consume electricity under 12 units.
A 3kW solar panel can power the following appliances.
Fans
Inverter Air Conditioner (under 1 tonne)
LED Lights
Washing Machine
LED TV
Dishwasher
Wifi Router
Microwave Oven
Refrigerator
A 3kW PV system can generate enough energy to power a home with 12 units per day energy demand. However, consumers can save around 70,000 to 90,000 based on electricity rates through net metering.
Interestingly, a 3kW solar panel system is enough for a small home or shop. It can generate sufficient power for home appliances and benefit consumers through net metering at the same time. However, a 3kW solar panel would not bear the energy load for bigger houses. And for that, higher capacity solar panels (5kW, 10kW, 20kW) are available in the market.
If your daily electricity consumption is between 10 to 12 units, then a 3kW solar system would be best for you.
