Your roof powers the house by day. The surplus goes to the grid. Your bill is worked out on the net.
An on-grid system is the simplest and most cost-effective way to bring down an electricity bill. There is no battery to buy or replace. Paso Solar sizes it to your usage and roof, installs it, and supports the net metering application with your DISCOM.
An on-grid system lowers your bill in two ways. Understanding both helps you size it sensibly.
Every unit your panels feed straight into the house is a unit you do not buy from the grid at full tariff. This is the largest part of the saving, so the more of your use that falls in daylight, the better on-grid works.
When the panels make more than the house is using, the extra goes to the grid. Where net metering is approved, your meter records it and the DISCOM adjusts it against what you draw later, at the rate set by their policy.
No fuel, no battery replacement. Upkeep is panel cleaning and a periodic check. Once it is paid off, the electricity it makes is effectively free for the life of the panels.
Grid tariffs tend to rise most years. The share of your electricity you generate yourself is not exposed to those increases.
A unit you use yourself is usually worth more than a unit you export, because the export credit is often lower than the retail tariff. That is why we size the system to your own consumption rather than as large as the roof allows.
In plain terms, the grid does the job a battery would.
Your panels power whatever the house is using at that moment. If they make more than you need, the extra flows out through the meter to the grid.
The house runs on the grid as it always did. There is no battery holding solar power back for later.
Where net metering applies, the DISCOM works out the difference between the units you imported and the units you exported, and bills you on that net figure.
The system switches off for safety until the grid returns. An on-grid system on its own does not give you backup.
Fewer parts than any other type of solar system, which is part of why it costs less and needs less looking after.
Sized to your roof and usage, on a structure rated for local wind conditions.
Converts DC to AC and manages the flow between your home and the grid. It also shuts the system down automatically if the grid fails.
A meter that records what the system produces, and the DISCOM's bidirectional meter that records import and export.
AC and DC isolation, surge protection, and earthing to the standard your connection requires.
An app or portal so you can see daily generation and spot a problem early.
Reference ranges only. We confirm capacity, generation, and roof area after a site check.
Net metering is granted by your DISCOM, subject to their current policy, feeder capacity, and sanctioned load. We prepare and file the application with you and follow it through to meter change and commissioning, but the approval and the credit terms are set by the utility, not by us.
On-grid works hardest where the grid is dependable and a good part of the electricity use happens in daylight.
Reliable grid connection and some daytime use at home.
Lights, fans, air-conditioning, and refrigeration running through business hours.
Steady 9-to-6 load that solar can cover directly from the roof.
High weekday daytime demand and large roof or shade-structure area.
The right choice comes down to whether you need backup and whether you have a grid connection at all.
Lowest cost. Biggest bill saving per rupee spent. No backup in a power cut.
You are hereGrid plus a battery. Keeps chosen loads running through an outage. Costs more.
CompareNo grid at all. Solar and batteries carry the whole load. For remote sites.
CompareNo. When the grid goes down, an on-grid system shuts off automatically so it cannot feed power back into lines that a lineman may be working on. Supply returns when the grid is back. If you need power through an outage, you need batteries, which means a hybrid or off-grid system.
No. An on-grid system uses the grid in place of a battery. You send surplus power out during the day and draw it back at night. A battery is only needed if you want backup during outages.
Where net metering is approved by your DISCOM, a bidirectional meter records the units you export as well as the units you import. Your bill is then raised on the difference. The credit rate, carry-forward, and any year-end settlement follow your DISCOM's current net metering policy, which we explain for your connection.
We look at your recent bills, how much of your use is in daytime, your usable roof area, shading, and your sanctioned load. A system much larger than your own consumption or your sanctioned load usually does not pay back well, so we size it to match.
A residential rooftop subsidy scheme applies to eligible homes and system sizes. We check what you currently qualify for and prepare the paperwork with you. Approval and the final amount rest with the authority.
You draw the balance from the grid and pay for it at your normal tariff. Any credit from power you exported earlier is adjusted first, where net metering applies.
Cleaning the panels a few times a year, more where there is heavy dust, and a periodic check of the inverter, wiring, and earthing. There is no battery to replace and no fuel to arrange.
