If your laptop, router and AC run all day, you are already a solar customer. Here is how to size it.

Working from home or running a small office turns your electricity meter into a daytime machine: computers, monitors, lights, router, printers and the air conditioner all run when the sun is up. That profile is ideal for solar. This guide on solar for work-from-home and small offices in Raipur explains how to size, back up critical equipment and understand the savings.
Quick answer: size the plant to your daytime consumption, add a small battery or UPS for the internet and computers, and use net metering to offset the rest.
| Equipment | Power | Daily use | Daily units |
|---|---|---|---|
| Laptop and monitor | 60 - 150 W | 8 - 10 hours | 0.5 - 1.5 |
| Desktop PC and monitor | 150 - 300 W | 8 - 10 hours | 1.5 - 3 |
| Router and modem | 10 - 20 W | 24 hours | 0.3 - 0.5 |
| LED lighting (6 points) | 60 W | 8 hours | 0.5 |
| 1.5 ton inverter AC | 1.0 - 1.5 kW | 8 hours | 8 - 12 |
| Printer and misc. | 50 - 100 W | Intermittent | 0.2 - 0.5 |
| Setup | Monthly units | Likely solar size |
|---|---|---|
| Single remote worker, AC used part-time | 250 - 350 | 2 - 3 kW |
| Home with two remote workers and ACs | 400 - 550 | 3 - 5 kW |
| Small office, 4 - 6 staff, one AC | 600 - 900 | 5 - 7 kW |
| Small office with 2 - 3 ACs | 1,000 - 1,500 | 8 - 12 kW |
A grid-tied plant switches off in a cut. For work continuity, add a small UPS or battery for the router, laptop and a few lights. A 1 to 2 kWh lithium or tubular battery with a small inverter can run these loads for hours. Avoid putting air conditioners on the backup circuit unless you accept a much larger system. See solar vs inverter UPS for home.
A home office on a domestic connection can claim the residential subsidy within the scheme's limits. A separate office on a commercial connection pays commercial tariffs and does not receive the residential subsidy, but may benefit from depreciation. Check your sanctioned load and tariff category before sizing.
A small office pays Rs 9,000 a month on a commercial tariff. A 7 kW system generates about 840 units a month and could offset most daytime consumption. Annual savings of around Rs 1 to 1.2 lakh are plausible, giving a payback of about four to five years on a cost of about Rs 4 to 5 lakh if no depreciation or incentive is counted. With depreciation, the effective payback is shorter. Treat these as screening estimates.
A studio on a commercial connection has four workstations, two monitors each, lighting, a router, a printer and one 1.5 ton AC running six to eight hours. Monthly use is about 780 units and the bill is about Rs 9,500. A 6 kW system generates roughly 720 units a month on average and offsets most daytime consumption. The studio keeps a 1 kVA UPS on the workstations and router, so a power cut gives staff time to save work, without paying for battery backup on the air conditioner. Annual saving is about Rs 1.0 to 1.2 lakh, and the owner discusses depreciation with the accountant before deciding between loan and cash.
Cooler rooms through summer afternoons, steady connectivity and predictable bills make work easier. Many owners report that the biggest benefit is not the rupee saving but not worrying about the electricity bill at all during peak summer months. Treat these as soft benefits and count the savings as the case.
If the plant is used for business, keep invoices, the commissioning report and loan documents for your accountant. Ask whether depreciation and GST input credit apply to your entity. Rules change each year, so confirm current provisions rather than relying on older advice.
If you work by day, solar works for you. The next step is a free survey.

Yes. Home offices use power by day, which solar generates, and backup for the router and laptop keeps work running in cuts.
A small office with four computers, lighting and one air conditioner may use 600 to 900 units a month, suggesting 5 to 7 kW.
A small battery or UPS for the router and laptop is usually enough. Full backup for ACs is much more expensive.
Only with the landlord's written consent and roof rights. Consider an arrangement that shares the savings.
The residential subsidy applies to homes. Offices benefit from lower bills and possible depreciation; ask your accountant.
