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.
Monthly electricity bills averaged around ₹12,000. Their high-consumer appliances included air-conditioners, water pumps, and multiple refrigerators.
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 (high efficiency) to maximize 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 which they’ll enjoy nearly “free” electricity (minus maintenance).

4. Non-Financial Benefits

Energy Independence: The family now relies much less on grid power.
Environmental Impact: Their system offsets ~8–10 tonnes of CO₂ emissions over 25 years.
Increased Property Value: Their house is now more attractive to eco-conscious buyers.
