Can Your House Run on a 5kW Solar System?

Due to their mix of high energy yields and excellent value for money, 5 kilowatt (5 kW) solar systems have grown to be one of the most popular sizes in India. Installing a solar energy system in your house is a wise and long-term investment. In order to make it simpler for householders to take advantage of renewable energy, the Indian government is also working to turn the nation into a “green economy.” What price points, electricity outputs, and monetary returns might a homeowner anticipate from a 5kW solar PV system? This article examines.

Considering what wattage the panels possess and how they’re angled, a modern 5kW solar system will consist of roughly 15-20 panels and require between 25 and 35 m2 of roof area. The size of a solar panel on a 5kW system is typically roughly 1.7 meters by 1 meter, though this might vary depending on the brand and whether it is intended for commercial or domestic usage.

Understanding your Cost and Capacity Requirements

A solar array with a 5kW capacity may produce up to 5kW of electricity for your home at its maximum output. The solar irradiance is not always at its peak (over 1000 kW/m2) during the day, so a 5kW system doesn’t constantly achieve its full energy-production threshold.

The overall cost of a 5kW solar system in India with a subsidy can decrease dramatically thanks to solar subsidies and practical financing choices, such as leasing and loan solar, and getting into long-term PPAs, or power purchase agreements. A 5kW solar system will typically cost between Rs 70,000 and Rs 1.5 Lakhs per kW, bringing the total cost to between Rs 3 Lakh and Rs 6.5 Lakhs. 

This cost is calculated without accounting for any potential residential solar system subsidies. Note that the developer will share the proposal with you after your site survey is done and determine the pricing based on any adjustments that your home requires. The location, type, and brand of solar components utilized, as well as the solar panels’ efficiency rating, will all have an impact on the precise cost of a 5kW solar panel system in India. Also, keep in mind that the following solar 5kW prices are approximations and do not include incentives.

Factors Affecting a 5kW Solar System

The true power output of a 5kW solar power system will vary depending on a variety of factors. These elements consist of:

✯The system’s geographic location, as well as the anticipated levels of daily and yearly solar radiation and cloud cover there.

✯Solar panel array orientation and tilt angle

✯Whether the panels are shaded in any way

✯The panels’ actual working temperature

✯The effectiveness of the separate parts

It’s also important to keep in mind that different places receive varied quantities of sunlight. The amount of sunlight that strikes a solar panel array directly affects how much energy the system produces. An approximate estimate for the amount of “peak sun”, also known as peak sun hours, that a rooftop receives annually is 4.5 hours per day. However, in more sun-witnessing areas, this number may be as high as 5.8 PSH and as low as 4.2 PSH. It’s crucial to bear in mind that this is merely the daily average for the year and that there will be more sun in the summer and less in the winter.

Key Considerations in a 5kW Solar System

Energy output: When purchasing a home solar system, system sizing is a crucial step that necessitates asking how many units are produced by 5kw solar panels. A 5kW solar system may produce 20 units daily on average of solar energy. This provides you with 600 units of solar electricity per month (20 units times 30 days), which adds up to 7,200 units in a year (600 units multiplied by 12 months).

Area needed: Do you have any idea how much roof space 5kW solar panels need? Residential solar panels typically measure 2 meters by 1 meter. If you use high-efficiency solar panels that lower the overall number of solar panels needed, this will require at least 30 square meters of your roof area or less.

Number of Solar Panels Required: If the efficiency is roughly 330Wp for a single solar panel, then you would need at least 15 panels for a 5kW solar system. You will require fewer solar panels if you take larger-capacity solar panels into account. Simply divide the total capacity by the efficiency of one solar panel to determine the number of solar panels needed to provide a given amount of power.

Warranty: You receive a 25-year performance warranty on your solar panels from the majority of solar system vendors. Depending on the brand you choose, the additional parts will have a product warranty of anywhere from 5 to 10 years.

Subsidy: In India, solar subsidies might lower the cost of your 5kW solar system. On-grid and hybrid solar systems, discounting the cost of solar batteries, are however eligible for solar subsidies for homes. Off-grid solar systems are not eligible for any subsidies.

Takeaway

A 5kW solar system lowers your monthly utility costs, which adds up to big savings over the course of a year and the solar panel system’s 25+ year lifespan. Your home will be powered entirely by solar energy from your solar panels, which will cut down on the amount of grid electricity you draw. In reality, under net metering, you have the chance to earn more money by selling extra solar energy to the grid in exchange for solar credits. Your own 5 kW solar system will therefore pay for the initial solar investment in 6 to 8 years, at which point all solar power units produced by your solar panels will be basically free for you.
