Real Case Study: How One Family Reduced Their Electricity Bill by 80% | Shyvon Power

"See how a middle-income household in India slashed its electricity bill by 80% using a rooftop solar system from Shyvon Power. Learn about system size, payback, and savings."

1. Background: Meet the Khanna Family

The Khanna family lives in a 4 BHK independent house in Ghaziabad, Uttar Pradesh. Their monthly electricity bills averaged around ₹12,000. High-consumption appliances, like air-conditioners, water pumps, and multiple refrigerators, contributed to these costs.

Motivated by rising power tariffs and environmental concerns, they decided to explore solar options in 2024.

2. Solar Solution by Shyvon Power

System Design & Installation

After a detailed site survey, Shyvon Power recommended a 7 kW on-grid rooftop solar system. They used monocrystalline solar panels for high efficiency, maximizing power per square foot.

A string inverter was installed, along with a robust mounting structure, DC and AC wiring, earthing, and surge protection. The structure was designed to minimize shading and maximize sun exposure throughout the year.

Net Metering & Subsidy

Shyvon Power helped them apply for net metering with the local DISCOM, allowing the surplus electricity to be exported. The Khannas were eligible for a residential solar subsidy under the relevant central/state scheme, reducing their upfront cost.

3. Financials: Cost, Payback & Savings

Metric	Value (Khanna Family)
System Size	7 kW
Approximate Installation Cost (before subsidy)	₹4.2 lakh
Subsidy Received	~₹80,000 (roughly)
Net Investment (after subsidy)	~₹3.4 lakh
	~900–1,000 units
Annual Solar Output	~10,800–12,000 units
Monthly Electricity Consumption (Old)	~1,000 units (~₹12,000 bill)
Monthly Self-Consumption of Solar	~800–900 units
Exported to Grid	~100–200 units
Monthly Grid Import After Solar	~100 units or less
New Monthly Bill	~₹2,200 (for grid import + fixed charges)
% Reduction in Bill	~80%

Payback Period

Based on their savings, the Khanna family is expected to recover their net investment in ~3–4 years. After that, they’ll enjoy nearly “free” electricity, minus maintenance costs.

4. Non-Financial Benefits

Energy Independence

The family now relies much less on grid power. This shift gives them a sense of freedom and control over their energy use.

Environmental Impact

Their system offsets approximately 8–10 tonnes of CO₂ emissions over 25 years. This positive impact contributes to a healthier planet.

Increased Property Value

Their house is now more attractive to eco-conscious buyers. Solar installations can boost property values significantly.

Peace of Mind

With low maintenance and a long-term warranty (25-year panel performance) via Shyvon Power, the family enjoys peace of mind.

5. Key Learnings & Best Practices

1. Correct Sizing Matters: The 7 kW system was well-chosen to match their consumption without a large excess.

2. Use High-Efficiency Panels: This helps maximize electricity generation, especially in urban homes with limited roof space.

3. Apply for Net Metering: This allows exporting surplus energy and reducing grid dependency.

4. Leverage Subsidy: Even partial government support significantly lowers payback time.

5. Regular Monitoring: Shyvon Power set up a monitoring system so they can track daily generation, detect issues, and ensure optimal performance.
