Choosing a solar company in Patna is a big decision. This detailed guide explains services, cost, subsidy, the installation process and how to avoid mistakes. It is written by ASAWAR KRISHI ENERGY, a Bihar-based solar company serving Patna, Vaishali and Araria. Also read our checklist for the best solar company in Patna.
What Does a Solar Company in Patna Actually Do?
A good solar company in Patna does far more than put panels on a roof. It studies your electricity bills, visits your property, designs the right system size, arranges approvals and subsidy paperwork, installs the system safely, connects the net meter and then looks after the plant for years. ASAWAR KRISHI ENERGY follows exactly this complete approach for homes, shops, schools, hospitals, farms and factories across Patna and Bihar.
In simple words, a solar company in Patna should be able to answer four questions for you: how much solar do I need, what will it cost after subsidy, how fast can it be installed, and who will service it later? If a company cannot answer these clearly in writing, keep looking.
- Survey and design: roof measurement, shade study, load calculation and layout, which is the base of every good solar panel installation in Patna.
- Supply and installation: panels, inverter, structure, cables, earthing and protection devices fitted by trained technicians.
- Approvals and subsidy: registration, documents, discom inspection and net-metering under PM Surya Ghar Muft Bijli Yojana.
- After-sales: cleaning, monitoring and solar panel repair, which decide how much your system really earns for 25 years.
Why Patna Is Ready for Solar Power in 2026
Patna gets strong sunshine for most of the year, rooftops are available in almost every locality, and electricity bills keep rising. That is why every month more families approach a solar company in Patna to cut their bills and protect themselves from power cuts. Three reasons make 2026 a very good time to go solar:
- Government subsidy: the central scheme gives up to ₹78,000 for a 3 kW home system, and Bihar has reported an additional state top-up (see the subsidy table below).
- Free units and net-metering: Bihar has announced 125 free units for domestic consumers, and a rooftop system with net-metering can bring the rest of your bill down further. Visit our homepage to see how we explain the savings.
- Better technology: efficient panels, smart inverters and long-life lithium solar batteries have made systems more reliable than ever.
For businesses the case is even stronger, because commercial tariffs are higher and daytime load matches solar generation. Read about our commercial solar panel systems to see how shops, schools and hospitals save every month.

Solar Subsidy in Patna: Central and Bihar Support
Subsidy is the biggest reason families contact a solar company in Patna. Under PM Surya Ghar Muft Bijli Yojana, eligible homes get a direct central subsidy. Bihar has also been reported to add a state top-up. Use the table as a guide and always confirm the current status before applying:
| System size | Central subsidy | State top-up (reported) | Total up to |
|---|---|---|---|
| 1 kW | ₹30,000 | up to ₹10,000 | ₹40,000 |
| 2 kW | ₹60,000 | up to ₹20,000 | ₹80,000 |
| 3 kW and above | ₹78,000 | up to ₹20,000 | ₹98,000 |
Note: the state figures come from news reports and can change, so we verify them for you at the time of application. A bank loan of up to ₹2 lakh at about 5.75% interest has also been reported for 3 kW home systems. Try our solar subsidy calculator for a quick estimate, or ask our team through the free solar energy system consultation.
Documents usually needed: latest electricity bill, Aadhaar, bank account details and a roof photo. We check every document, because small mistakes are the most common reason a subsidy gets delayed. See our solar subsidy assistance service.
How Much Solar Does Your Patna Home Need?
Your solar company in Patna should size the system from your real bills, not from a fixed package. As a thumb rule, 1 kW of solar produces about 120 units a month in Patna on average over the year and needs roughly 80 to 100 sq ft of shade-free roof.
| System | Units per month | Roof area | Suits |
|---|---|---|---|
| 1 kW | ~120 | 80–100 sq ft | Small home: lights, fans, TV, fridge |
| 2 kW | ~240 | 160–200 sq ft | Typical family home |
| 3 kW | ~360 | 240–300 sq ft | Larger home with 1–2 ACs |
| 5 kW | ~600 | 400–500 sq ft | Big home, EV charging, many ACs |

Whatever your need, a single solar company in Patna that handles design, installation, wiring (solar electrician) and service saves you from chasing three different vendors.
Solar, EV Charging and HVAC: The Next Step for Patna
Electric vehicles and air conditioners are the two fastest growing loads in Patna homes and businesses. A forward-looking solar company in Patna should plan for both. Daytime EV charging uses solar power very efficiently, and cooling load peaks exactly when the sun is strongest. Our guides explain how to power an electric vehicle charging station with solar and how to cut cooling bills by pairing your HVAC system with solar.
Mistakes to Avoid When Choosing a Solar Company in Patna
- Choosing only on price. The cheapest quote often uses weak structures or thin cables. Compare components and warranty, as explained in our guide to the best solar company in Patna.
- No site survey. A quote without visiting your roof is a guess.
- Oversized systems. Pay only for the units you will actually use.
- No plan for service. Ask who will handle solar panel maintenance and repairs.
- Missing subsidy support. Make sure the company handles paperwork end to end.
- Verbal promises. Get capacity, brands and warranty in writing.
Types of Solar Systems a Solar Company in Patna Will Offer
Every reliable solar company in Patna should explain the three basic system types before quoting. The right choice depends on your power supply and how much backup you need.
| Type | How it works | Best for | Subsidy |
|---|---|---|---|
| On-grid | Connected to the grid with a net meter. No battery. | Homes and businesses with reliable supply and daytime load | Eligible for PM Surya Ghar |
| Hybrid | Grid plus battery backup. Saves on bills and runs essentials in outages. | Homes, clinics and shops with frequent cuts | Depends on design |
| Off-grid | Fully independent with battery storage. | Farmhouses and remote sites | Usually not for home scheme |
We explain each type in detail on our on-grid, off-grid and hybrid guide. If you are unsure, our solar energy system consultation is free.
Cost of Solar in Patna: What Decides the Price?
The cost of a solar system in Patna is not one fixed number. A fair solar company in Patna shows you exactly what you are paying for. These factors decide the final price:
- System size in kW: larger systems cost more in total but less per kW.
- Brand and efficiency of panels and inverter.
- Roof type and structure: an elevated structure on an RCC terrace costs more than a flat low-height one.
- Cables, protection and earthing: the safety parts you should never compromise on.
- Battery: adding lithium batteries raises the cost but gives power backup.
- Subsidy: reduces your real cost; check it in the solar calculator.
Payback: many Bihar homes recover their investment in a few years through lower bills, and then enjoy low-cost power for the remaining life of the panels, which is 25 years or more. We share a realistic payback estimate in every written proposal rather than a generic number.
Net Metering Explained by a Solar Company in Patna
Net metering is what lets your rooftop system work with the grid. During the day your home uses solar power first, and extra power goes to the grid. At night you take power from the grid, and the units exported are adjusted against the units imported in your bill. A good solar company in Patna coordinates the application, the inspection and the meter installation so you do not have to run between offices.
- Step 1: system is installed and tested.
- Step 2: the discom inspects it.
- Step 3: a bidirectional net meter is fitted.
- Step 4: subsidy is released after commissioning under PM Surya Ghar.
Solar Maintenance Tips From a Solar Company in Patna
Dust is the biggest enemy of solar output in Bihar. Our solar panel maintenance team recommends cleaning every 2 to 4 weeks in the dry season and a full electrical check once or twice a year. Never use high-pressure water, detergents or abrasive pads and do not walk on panels.
- Watch daily generation on your inverter or app. A sudden drop means call a technician.
- Keep the area around the inverter ventilated and dust free.
- Trim trees or move objects that create shade.
- Book a pre-monsoon inspection of seals, earthing and surge protection.
- If something looks wrong, our solar panel repair team can diagnose it quickly.
