Understanding the Photovoltaic Effect
Solar panels are made up of small units called photovoltaic (PV) cells. When sunlight hits these cells, it creates an electric field that causes electrons to flow, generating direct current (DC) electricity.
In the context of Lucknow, our city receives approximately 300 days of clear sunshine per year, making it one of the most efficient regions in India for solar energy harvesting.
Key Components of a Home System
- Solar PV Modules: The panels installed on your rooftop.
- Solar Inverter: Converts DC electricity to AC (Alternating Current) used by your home appliances.
- Net Meter: A bidirectional meter that records electricity sent to and taken from the grid.
- Mounting Structure: High-quality GI structures designed to withstand Lucknow's storm winds.
The Role of Net Metering in Lucknow
Under the current UPNEDA (Uttar Pradesh New and Renewable Energy Development Agency) guidelines, Lucknow residents can benefit from "Net Metering." This means any excess electricity generated by your panels during the day is sent back to the MVVNL grid.
At night, when your panels aren't producing power, you draw electricity from the grid. Your monthly bill is calculated based only on the "Net" consumption.
Lucknow-Specific Maintenance Tips
Lucknow's environment can be quite dusty, especially during the pre-monsoon summer months (April-June). Dust accumulation on panels can reduce efficiency by as much as 25%.
Regular Cleaning
Clean your panels with plain water every 15 days to remove settled dust and bird droppings.
Morning Cleaning
Always clean panels early in the morning when they are cool. Cleaning hot panels with cold water can cause micro-cracks.
Frequently Asked Questions
Does solar work on cloudy days in Lucknow?
Yes, solar panels still produce electricity on cloudy days using diffused sunlight, though at a lower efficiency (about 10-25%).
How much roof space do I need for 1kW?
A standard 1kW installation requires approximately 100 square feet of shadow-free rooftop space.
