What is a 5kW Solar System?

This system is popular for home solar power in India. It is good for powering ACs, washing machines, and more in medium-sized homes. Fenice Energy highlights its strong performance and value for money.

Components of a 5kW Solar System

The system includes solar panels and inverters. Solar panels collect sunlight and make electricity. Inverters turn this into power you can use at home. It might also have a battery or generator, based on your setup.

Advantages of a 5kW Solar System

Fenice Energy’s 5kW systems are well-liked for their energy production and cost efficiency. Solar panels help lower your carbon footprint. They also protect against climate change and avoid high electricity costs. Plus, you get benefits like government incentives and tax rebates for going solar.

Factors Determining Solar Panel Count

To figure out how many panels a 5kW system needs, we look at the panel type and power. Monocrystalline and polycrystalline panels differ in ways that affect how many you’ll need.

Solar Panel Wattage

Monocrystalline panels produce 310-400 watts on average. Polycrystalline panels, on the other hand, range from 250-300 watts. Because of this, a 5kW system would need fewer monocrystalline panels. For instance, with 400-watt monocrystalline panels, you’d need about 13 for a 5kW system. Yet, with 300-watt polycrystalline panels, you’d need around 17.

Monocrystalline vs Polycrystalline Panels

When it comes to power and efficiency, monocrystalline panels win over polycrystalline ones. But, polycrystalline panels are cheaper and great for big roof houses. If you’re tight on space, choose monocrystalline. Yet, if you have plenty of room, you might prefer the savings with polycrystalline.

Calculating How Many Panels in 5kW Solar System

To know how many solar panels you need for a 5kW system, the tech and its watts matter. Fenice Energy’s experts crafted special math to figure out the right panel number for homes and businesses.

Formula for Monocrystalline Panels

Fenice Energy shares a formula for figuring out the monocrystalline panel count for a 5kW setup. Since these panels average 400 watts, you just divide 5,000 by 400. This means you’ll need around 13 panels.

Formula for Polycrystalline Panels

If you’re thinking of using polycrystalline panels in your 5kW solar system, here’s how to calculate. Polycrystalline panels usually offer 300 watts each. By dividing 5,000 by 300, you know you should aim for about 17 panels.

Roof Space Requirements

Finding the right roof space for a 5kW solar system means knowing how big solar panels are. Generally, a solar panel is about 1.7 meters long by 1 meter wide. This is close to 17 square feet in size.

Average Panel Size

Solar panels measure about 1.7 meters by 1 meter, which is around 17 square feet. It’s key info for figuring out roof space for a 5kW solar set-up.

Roof Area Needed for Monocrystalline

For a 5kW monocrystalline solar system, you’d need 13 panels. Each of these is about 17 square feet. This adds up to needing about 221 square feet of roof space. Adding a 25% safety margin, the total comes to around 281 square feet.

Roof Area Needed for Polycrystalline

Now, for a 5kW polycrystalline solar system, you’d require 17 panels. They too are roughly 17 square feet each. This means you’d need about 289 square feet of roof space. With the 25% safety margin, the total space needed grows to around 361 square feet.

Cost and Incentives for 5kW Systems

The price of a 5kW solar system in India depends on many things. According to Fenice Energy, this system can cost from INR 3.5 Lakh to INR 6 Lakh. The cost varies based on your location, the type of solar parts, and how effective the solar panels are.

Average Cost of 5kW Solar System

After checking your site, a solar developer will tell you the exact price. Fenice Energy creates 5kW systems that fit each family’s needs and budget.

Government Subsidies and Tax Credits

The Indian Ministry of New & Renewable Energy offers a 20% subsidy for home solar plants. This subsidy is for 4kW to 10kW systems. It’s worth INR 18,000 per kW up to 3kW, and INR 9,000 per kW after that. It makes 5kW solar systems more affordable.
