Mathematically, 1500 sq. ft is approximately 168.57 gaz which is considered into mid-size property for a home.
Modern duplex houses generally fall into this category.
Though the space is large, how much solar panels are required, and how much solar panels cost is an important subject to know before installing solar panels.
This blog will discuss solar panel costs for homes, especially for a 1500-square-foot house.
How Do 1500sq. ft. Solar Panel System Work?
It is pretty awesome to know about how the solar system works for home.
- Solar panel cells absorb sunlight
- Boards then convert the light into DC power
- With the help of an inverter DC power converts into AC power
- The electricity is then sent through wires into your home
- Any excess of electricity produced is then fed into the electric grid
Did you know the Discom department provides monetary benefits for feeding access power back to them? The process is called Net Metering.
How Long Do 1500sq. Ft. Solar Panels Last?
Solar panels or sun-based boards come with a prolonged warranty. In figures, all solar panels come with at least 25 years of efficiency.
In short, an efficient solar panel can last up to 25 years or even longer.
According to a study conducted by the Renewable Energy Department of India, solar panels last 80% longer than their efficiency.
How Many Solar Panels Do I Need for a 1,500 Square Foot Home?
Let’s do the math…!
The 1kW solar panel system consists of 335 watts x 3 Nos. Hence, 3 solar panel boards are used. The 1kW solar system is used in homes within 300 sq. ft.
Considering the 1500 sq ft area, a 5kW solar panel system is required. This means 335watt x 15 Nos solar panels are required.
Hence, 15 solar panel boards are required to compete with 1500 sq. ft homes.
How Much 5kW Solar Panel System Cost For 1500 sq. ft. Homes?
A 5kW solar system generates 5000 watts in a day.
This figure is ideal for taking the recommended load as mentioned below:
|Applicable loads||Load||Back-up time|
|8 LED Lights + 2 Fan + 2 ton AC+ Fridge||4000 watt||5 Hours|
|12 LED Lights + 6 Fan + 2 Cooler+ Fridge+ 1 TV||2500 watt||8 Hours|
|12 LEDs + 6 Fan + Fridge+ 1 TV+ Washing Machine+1 Cooler||2000 watt||12 Hours|
Now talking about the cost for a 1500 sq. ft house with 15 nos solar panels is discussed below:
A) On-Grid 5kW Solar System Cost
Grid-tie connection as per Rs.60 price per watt will cost you Rs. 3,00,00.
B) Off-Grid 5kW Solar System Cost
Non-grid connection as per Rs.70 per watt will cost homeowners Rs. 3,50,000.
C) Hybrid 5kW Solar System Cost
Solar panel connection with combined connection methodology will cost Rs. 4,00,00 as per Rs.80 price per watt.
