How to Choose the Best Solar Panel Technology for Your Rooftop ?

JaiKisaan provides expert advice to help you select the most suitable solar panels for your requirements:

  • Monocrystalline Panels: Known for their high efficiency, these panels are perfect for rooftops with limited space. While they come at a higher cost, they deliver maximum energy output.
  • Polycrystalline Panels: A budget-friendly option, these panels work well for installations with abundant space and ample sunlight.

Jaikisaan helps you comprehend the key differences and choose the most suitable system:

  • On-Grid Systems: These are connected to the utility grid, enabling you to export surplus energy and earn credits through net metering. However, they do not offer power backup during outages.
  • Off-Grid Systems: Operating independently from the grid, these systems use battery banks for energy storage, ensuring power availability during outages. While they provide backup, they require regular maintenance and are more expensive due to the cost of batteries.
  • On-Grid Systems: Lack of power backup during outages.
  • Off-Grid Systems: Depend on costly, bulky battery banks that require regular maintenance and have a higher environmental impact. Additionally, batteries may fall short of meeting the complete energy demands of a home or office.
  • Net Metering: Excess electricity is exported to the grid and adjusted against your consumption. A bidirectional meter records both import and export, and compensation depends on your state’s policy.
  • Gross Metering: All electricity generated by your solar plant is exported to the grid at a fixed feed-in tariff. You pay the utility for electricity consumed from the grid at retail rates.
  • Net Billing: Net billing is similar to net metering, but instead of reducing your electricity bill with the extra energy you send to the grid, the utility company pays you for it at a fixed rate (usually lower than what you pay for grid electricity). The energy you use from the grid is charged at full price.
  • Cloudy Days: Panels can still generate power using diffused sunlight, though the output may drop by 10–25%.
  • At Night: Panels do not generate electricity, but hybrid systems with batteries can supply stored energy.

Jaikisaan suggests using smart inverters and monitoring apps to track real-time energy generation, consumption, and system performance.

Solar panels have a lifespan of 25–30 years with minimal maintenance. However, inverters and batteries may require replacement every 5–15 years. Jaikisaan ensures the use of durable, high-quality components for longevity.

How Much Can You Save with a Solar System?

Your savings depend on factors like the system size and electricity rates. For example, a 1kW on-grid system generating 120 units per month at a tariff of ₹7.5/unit can save you approximately ₹900 monthly

Subsidies are offered for residential solar installations up to 10kW, subject to state policies. Visit your state’s Renewable Energy Agency website to check specific subsidy schemes before installation.

Jaikisaan streamlines the process by preparing a detailed RFP (Request for Proposal) with specifications and standards. Verified EPC (Engineering, Procurement, and Construction) companies bid on your project, allowing you to compare pricing, quality, and eSunScope's recommendations to select the best installer for your needs and budget.

The price varies based on panel technology, inverter type, and structure. A typical 1kW on-grid system costs between ₹40,000 and ₹45,000

The required area depends on the type of solar panels. Monocrystalline panels need approximately 8 square meters per 1kW, while polycrystalline panels require around 10 square meters for the same capacity.

Solar panels have minimal maintenance needs as they have no moving parts. Basic cleaning twice a month is recommended, and the inverter might need replacement every 10–12 years.

Maintenance costs are low, involving regular cleaning and occasional professional inspections. Jaikisaan offers maintenance guidelines and connects you with trusted service providers.
