We didn't set out to sell solar panels. We set out to change how India powers itself — one home, one farm, one community at a time.
We believe clean energy is not a luxury.
It is a right — accessible to every home, every field, every community.
— The SunVana Mission
"Every watt of clean energy is a step away from dependence — on fuel, on the grid, on the old way of doing things."
SunVana Energy was founded with a single conviction: that India's energy future must be clean, decentralized, and fair. With some of the world's highest solar irradiance, the opportunity to power the subcontinent through the sun has always been immense.
We built SunVana to close that gap. Based in Bangalore and serving clients across Karnataka and beyond, we combine cutting-edge solar engineering with hands-on human support — guiding every client from first conversation to long-term operation.
Our name says it all: Sun + Nirvana. A state of balance, achieved through the limitless, free energy of the sun. That's the philosophy behind every system we design, every installation we commission, and every rooftop we transform.
Today, we work with homeowners, farmers, industrialists, and institutions — delivering residential, agricultural, commercial, and hybrid energy solutions built to last for decades.
The original, inexhaustible source. 5 billion years of energy, free for the taking. We simply put it to work for you.
Two ideas, fused into a single purpose. The physics of solar energy, married to the philosophy of harmony.
Liberation. The state of being free from dependence, from volatility, from the rising and falling of electricity tariffs.
Our values are not aspirational posters on a wall. They are the decisions we make every day — in how we design systems, how we treat clients, and how we measure our own success.
No two energy needs are identical. We refuse to sell off-the-shelf solutions. Every system built from the ground up around your goals.
A solar system is a 25-year relationship. We design, install, and maintain with that timeline in mind — success measured in decades.

Full off-grid wind systems with lithium or lead-acid battery banks for remote homes, telecom towers, agricultural pump houses without grid access.
A solar-wind hybrid system is the most reliable off-grid or backup energy solution available. Solar panels generate peak power during clear daylight hours. Wind turbines pick up at night, during cloudy weather, and especially during the monsoon — the season solar underperforms most. Together, they provide near-continuous generation across every season.
Coastal Karnataka (Mangalore, Udupi, Karwar) and hilltop locations see consistent wind speeds of 5–8 m/s — ideal for standalone or hybrid wind systems.
Open agricultural land with minimal obstructions sees reliable wind, especially in the Deccan Plateau region. Ideal for solar-wind hybrid farm systems.
Urban areas have turbulent, unpredictable wind patterns. VAWT turbines work better here than HAWTs, but a site wind study is essential before investing.
Islands (Lakshadweep, Andaman) and remote sites with no grid access are among the best wind-hybrid candidates — replacing expensive diesel with free, clean energy.
High-rainfall areas where solar underperforms in Jun–Sep benefit greatly from solar-wind hybrids — wind compensates exactly when solar is weakest.
Heavily built-up urban areas with surrounded buildings and low wind speed (under 3 m/s) are rarely viable for wind alone. Solar rooftop is a better choice here.

Going solar is one of the most significant financial decisions a homeowner can make — and also one of the most rewarding. This guide breaks down exactly what a rooftop solar system costs in India in 2025, which subsidies you can claim, and how to calculate your payback period to the month.
Solar prices in India have fallen dramatically over the past decade. In 2025, a grid-connected rooftop solar system costs between ₹55,000 and ₹75,000 per kW for a complete, installed system — panels, inverter, mounting structure, wiring, and net metering. The exact figure depends on the brand of components, your roof type, and local installation complexity.
For a typical Bangalore home consuming 400–600 units per month, a 5 kW system is often the right size — bringing the total installed cost to approximately ₹2.75 lakh to ₹3.75 lakh before subsidies.
| System Size | Est. Cost (Before Subsidy) | PM Surya Ghar Subsidy | Net Cost | Monthly Generation |
|---|---|---|---|---|
| 1 kW | ₹65,000–₹75,000 | ₹30,000 | ₹35,000–₹45,000 | 120–140 units |
| 2 kW | ₹1.30–₹1.50 lakh | ₹60,000 | ₹70,000–₹90,000 | 240–280 units |
| 3 kW | ₹1.95–₹2.25 lakh | ₹78,000 | ₹1.17–₹1.47 lakh | 360–420 units |
| 5 kW | ₹2.75–₹3.75 lakh | ₹78,000 | ₹1.97–₹2.97 lakh | 600–700 units |
| 10 kW | ₹5.50–₹7.50 lakh | ₹78,000 | ₹4.72–₹6.72 lakh | 1,200–1,400 units |
The PM Surya Ghar Muft Bijli Yojana subsidy is capped at ₹78,000 regardless of system size above 3 kW. This means smaller systems get a proportionally larger subsidy benefit — a 3 kW system effectively gets 35–40% off.
Before sizing a solar system, you need to understand your current consumption and tariff slab. BESCOM (Bangalore's electricity provider) uses a tiered tariff structure — the more you consume, the higher the rate per unit. Heavy consumers pay ₹7.40–₹8.50 per unit, making solar savings much larger for high-bill households.
| Monthly Units | Rate per Unit | Typical Monthly Bill |
|---|---|---|
| 0–50 units | ₹3.05 | ₹150–₹200 |
| 51–100 units | ₹5.45 | ₹400–₹600 |
| 101–200 units | ₹6.10 | ₹800–₹1,400 |
| 201–500 units | ₹7.40 | ₹1,500–₹4,000 |
| Above 500 units | ₹8.50 | ₹4,000+ |
If your home consumes 400 units per month at ₹7.40/unit, you're spending roughly ₹3,000 per month or ₹36,000 per year. A 3–4 kW solar system can offset 80–100% of this bill.
The payback period is the number of years it takes for cumulative electricity savings to equal your initial investment. Here's how to calculate it step by step:
Profile: 4-bed house, 500 units/month, bill ₹4,000/month
System: 5 kW, installed cost ₹3.50 lakh, subsidy ₹78,000, net cost ₹2.72 lakh
Annual generation: ~7,000 units · Annual savings: ₹59,500 at ₹8.50/unit
Payback period: 4.6 years · Profit over 25 years: ~₹12 lakh
Lithium-ion battery storage adds ₹60,000–₹1,20,000 per 5 kWh of capacity to your system cost. For most grid-connected Bangalore homes, batteries are optional — net metering effectively acts as your "grid battery." However, if power cuts are frequent in your area or you need backup for critical loads, a battery adds significant value.
Not all solar quotes are equal. The three components that most impact long-term performance and value are:
The biggest decision when going solar isn't which brand of panel to buy — it's which type of system to install. On-grid, off-grid, and hybrid systems each work very differently and suit very different situations. Here's everything you need to know to choose the right one.
Connected to the utility grid. Exports surplus power and earns credits. Shuts down during power cuts for safety.
Completely independent from the grid. Requires battery storage to power the home at night or on cloudy days.
Connected to the grid AND has battery storage. Powers home during cuts, exports surplus, maximum flexibility.
An on-grid (or grid-tied) solar system is connected to your local electricity grid via a bidirectional meter. During the day, your panels generate electricity that powers your home first. Any surplus is exported to the grid and credited to your electricity bill — this is called net metering.
On-grid systems have a critical safety feature: they automatically shut down during a power cut. This is required by regulation to prevent your inverter from back-feeding live current into grid lines where technicians may be working. It means you have no power during outages — even when the sun is shining.
Homes and businesses in areas with reliable grid supply (fewer than 2–3 cuts per month), and anyone prioritising lowest upfront cost and fastest payback. The most popular choice in Bangalore's well-supplied layouts.
An off-grid system has no connection to the electricity grid. It relies entirely on solar panels to charge a battery bank, which then powers your home 24 hours a day. These systems must be sized very carefully — the battery bank must be large enough to carry the home through multiple cloudy days without sunlight.
The main drawback is cost. A true off-grid system requires 2–3× more battery capacity than a hybrid system, significantly raising the upfront investment. Battery replacement every 8–12 years also adds to the long-term cost.
Remote properties with no grid access or extremely unreliable supply. Agricultural pump houses, rural homesteads, and sites where the cost of grid extension exceeds the cost of a standalone solar system.
A hybrid system combines the best features of both on-grid and off-grid. It is connected to the grid (enabling net metering and grid backup) but also has battery storage (enabling power during outages). A hybrid inverter intelligently manages all three power sources — solar, battery, and grid — in real time.
Homes and businesses in areas with frequent but not constant power cuts (1–6 hours per day). The fastest-growing segment in Bangalore as battery prices continue to fall. Ideal for families that cannot tolerate downtime — home offices, medical equipment, security systems.
| Feature | On-Grid | Off-Grid | Hybrid |
|---|---|---|---|
| Upfront cost | Lowest | Highest | Medium |
| Works during power cut? | No | Yes | Yes |
| Net metering eligible? | Yes | No | Yes |
| Battery required? | No | Yes (large) | Optional |
| Payback period | 4–6 years | 8–12 years | 5–7 years |
| Grid connection required? | Yes | No | Yes |
| Best for | Urban homes, reliable grid | Remote, no grid | Urban + backup needs |
| Subsidy eligible? | Yes | Limited | Yes |
For most Bangalore homeowners with a reasonably reliable grid supply, an on-grid system delivers the fastest payback and best return on investment. If you experience frequent cuts of 2–4 hours per day, a hybrid system with a 5–10 kWh battery is worth the extra investment for the peace of mind alone. Off-grid is only recommended for genuinely remote locations.
The good news: if you install an on-grid system today, most modern hybrid inverters allow you to add batteries later as a retrofit — so you don't have to decide everything upfront.
Launched in February 2024, the PM Surya Ghar Muft Bijli Yojana is the largest solar subsidy programme India has ever seen — with ₹75,021 crore allocated and a target of 1 crore rooftop solar installations. Here is exactly how to claim your subsidy, step by step.
Announced by PM Modi in February 2024, this scheme provides direct benefit transfer (DBT) subsidies to homeowners installing grid-connected rooftop solar systems. The goal: enable 1 crore households to generate their own clean electricity, reduce electricity bills to near zero, and earn income by selling surplus power back to the grid.
Unlike older MNRE schemes that routed subsidies through installers, PM Surya Ghar pays the subsidy directly into your bank account within 30 days of installation and inspection — making it faster and more transparent.
| System Size | Central Subsidy | Subsidy as % of cost |
|---|---|---|
| 1 kW | ₹30,000 | 40–45% |
| 2 kW | ₹60,000 | 40–46% |
| 3 kW | ₹78,000 | 35–40% |
| 4 kW and above | ₹78,000 (capped) | 20–28% |
The subsidy is calculated as ₹30,000 per kW for the first 2 kW, then ₹18,000 for the third kW — and is capped at ₹78,000 regardless of larger system sizes. Some states also offer an additional top-up subsidy; Karnataka offers further support under its own renewable energy policy.
The subsidy only applies to residential rooftop installations by homeowners. It does not apply to commercial, industrial, or housing society common area installations (though those may be eligible under separate commercial schemes).
SunVana manages the entire PM Surya Ghar subsidy process for our customers — from portal registration to BESCOM coordination to subsidy follow-up. You don't need to navigate the bureaucracy yourself.
Buying solar in Bangalore involves BESCOM regulations, Karnataka-specific subsidies, monsoon considerations, and a market full of installers ranging from excellent to unreliable. This guide gives you everything you need to make a confident, well-informed decision.
Your starting point is your electricity bill. Look at the last 12 months of bills and calculate your average monthly consumption in units (kWh). In Bangalore, most 2–3 BHK apartments consume 200–350 units per month; independent houses and villas typically consume 400–800 units depending on air conditioning usage.
A correctly-sized system should generate 80–100% of your annual consumption. Oversizing wastes money; undersizing means you're still paying significant bills.
Not every roof is created equal. The key factors that affect how much solar your roof can generate are:
Bangalore receives excellent solar irradiance of 5.0–5.5 kWh/m²/day for most of the year. Even during the monsoon months (June–September), panels generate 60–70% of their peak capacity. Annual generation estimates for Bangalore are reliable and consistent.
Net metering allows your surplus solar generation to flow into the BESCOM grid, and your meter runs backwards — you get credited for every unit exported. The current BESCOM net metering export rate is approximately ₹3.50–₹4.50 per unit.
BESCOM's net metering application takes 30–60 days from installation. Your installer must handle the technical inspection and meter upgrade. SunVana manages the complete BESCOM filing process for all our installations.
Once you receive quotes from 2–3 installers, compare them on these specific parameters — not just total price:
| Parameter | What to Look For | Red Flag |
|---|---|---|
| Panel brand | Tier-1: Jinko, LONGi, REC, Waaree, Adani | Unknown Chinese brands, no datasheet |
| Panel efficiency | Above 20% (PERC or TOPCon) | Below 18% |
| Inverter brand | Sungrow, SMA, Fronius, Delta, Growatt | No Indian service centre |
| Panel warranty | 25-year performance, 12-year product | Less than 10-year product warranty |
| Inverter warranty | 5 years minimum (10 preferred) | Less than 3 years |
| MNRE registration | Installer on PM Surya Ghar portal | Cannot confirm subsidy eligibility |
| Generation estimate | Based on site-specific shadow analysis | Generic estimate without roof assessment |
Yes — convincingly. Bangalore's monsoon season (June–September) sees reduced direct sunlight but panels still generate from diffuse light. A well-designed 5 kW system will generate 400–500 units/month even in heavy monsoon months, compared to 650–750 units in peak summer months. Annual generation estimates account for this seasonal variation.
Understanding what goes into a solar system helps you evaluate quotes, ask the right questions, and avoid being sold inferior components at premium prices. Here is what each major component does and what the specifications actually mean.
Solar panels (photovoltaic modules) convert sunlight into DC electricity. In 2025, virtually all residential installations use either PERC (Passivated Emitter and Rear Cell) or the newer TOPCon (Tunnel Oxide Passivated Contact) monocrystalline cells — both offering efficiency above 20%.
| Spec | What it Means | Good Value (2025) |
|---|---|---|
| Watt peak (Wp) | Power output under standard test conditions (25°C, 1000W/m²) | 400–550 Wp per panel |
| Efficiency (%) | % of sunlight converted to electricity | 20–23% (PERC/TOPCon) |
| Temperature coefficient | Power loss per °C above 25°C | Below -0.35%/°C |
| Degradation rate | Annual power decline over system life | Below 0.55%/year |
| Product warranty | Manufacturer guarantee against defects | 12 years minimum |
| Performance warranty | Guaranteed output at end of 25 years | 80–84% of rated output |
Panels are rated at 25°C, but rooftop temperatures in Bangalore regularly reach 55–65°C in summer. A panel with a temperature coefficient of -0.40%/°C loses 12% of its power at 55°C. TOPCon panels have better high-temperature performance than older PERC technology.
Bloomberg NEF's "Tier-1" classification identifies manufacturers with strong financial backing and consistent quality control. Tier-1 brands for India include: Jinko Solar, LONGi Green Energy, REC Group, Waaree Energies, Adani Solar, and Vikram Solar. Tier-2 panels can be 15–20% cheaper but carry higher risk of early degradation and warranty claim difficulties.
The inverter converts DC electricity from your panels into AC electricity your home can use. It is the most technically complex component and — importantly — the component most likely to fail over a 25-year system life. Choosing a quality inverter with strong Indian service support is critical.
| Spec | What it Means | Good Value |
|---|---|---|
| Efficiency (%) | % of DC input converted to AC output | Above 97% |
| MPPT trackers | Circuits that maximise panel output | 2+ for complex roofs |
| IP rating | Weather/dust protection | IP65 minimum for outdoor |
| Warranty | Manufacturer guarantee | 5–10 years |
| Monitoring | App/portal for real-time data | Built-in Wi-Fi monitoring |
Battery storage allows you to store surplus solar generation for use at night or during power cuts. In 2025, lithium iron phosphate (LFP) batteries are the standard choice for residential solar — safer, longer-lasting, and more stable than older lithium-ion chemistries.
To power critical loads (lights, fans, Wi-Fi, some appliances) through a 4-hour power cut, most homes need 5–8 kWh of usable battery storage. For whole-home backup, plan for 10–15 kWh per 4 hours of full autonomy.
The mounting structure holds your panels on the roof for 25 years through heat, monsoon, and the occasional storm. Hot-dip galvanised steel or anodised aluminium are the only acceptable materials. Cheap unpainted iron structures rust within 3–5 years and can damage your roof. Always ask for the structure material and specification in your proposal.
Solar panels are often described as "maintenance-free" — and while they are low-maintenance, they are not zero-maintenance. Dust, soiling, and ageing components can quietly reduce your system's output by 10–30% if left unattended. Here is a practical guide to keeping your system performing at its best.
In Bangalore's environment, a combination of construction dust, bird droppings, and monsoon-deposited debris can reduce panel output significantly within a few weeks. The cleaning method matters — improper cleaning can scratch panel glass and reduce transmittance permanently.
Even partial shading from bird droppings on a single cell can cause "hot spotting" — where that cell heats up significantly under current mismatch. Prolonged hot spotting can permanently damage cells and in extreme cases cause fires. Remove bird droppings promptly.
Modern inverters include built-in Wi-Fi monitoring that streams real-time and historical generation data to your smartphone. Use this data actively — it is the earliest warning system for problems.
Beyond regular cleaning, an annual professional inspection should cover:
| Symptom | Likely Cause | Action |
|---|---|---|
| Generation 15%+ below expected | Soiling, shading, or string fault | Clean panels, check for new shading, call installer |
| Inverter showing red light / error | Grid fault, wiring issue, overtemperature | Note error code; call installer if persistent |
| Inverter not switching on at sunrise | DC isolator tripped, wiring fault | Check isolator switch; call installer |
| Electricity bill unexpectedly high | System underperforming or net meter error | Check monitoring app, contact BESCOM and installer |
| Visible panel discolouration | PID, delamination, or internal cell damage | Professional inspection, may need warranty claim |
Panels last 25–30 years. Inverters typically last 10–15 years and will likely need one replacement over a system's life. Plan for an inverter replacement cost of ₹30,000–₹80,000 depending on system size when budgeting your long-term solar economics.
Net metering is the mechanism that makes solar truly worthwhile in Bangalore — it allows you to earn credits for every unit of surplus solar electricity you export to the BESCOM grid. Here is how it works, what the rates are, and how to get connected.
When your solar panels produce more electricity than your home needs at any moment, the surplus flows back through your electricity meter into the BESCOM distribution grid. A bidirectional (net) meter records both the electricity you import from the grid and the electricity you export to it.
At the end of each billing cycle, BESCOM calculates your net consumption — units imported minus units exported. If your exports exceed your imports in a month, the surplus is carried forward as a credit for up to 12 months. At the end of the settlement year, any remaining surplus is paid out by BESCOM at the applicable export rate.
| Direction | Rate | Notes |
|---|---|---|
| Import (grid → home) | ₹3.05–₹8.50 per unit | BESCOM slab tariff based on monthly units |
| Export (solar → grid) | ₹3.50–₹4.50 per unit | Fixed rate set by KERC (Karnataka Electricity Regulatory Commission) |
| Net bill calculation | Import charges − Export credits | Billed monthly; credit carried forward 12 months |
| Year-end surplus payment | At export rate | Credited to bank account or adjusted in next year |
Because BESCOM's highest import tariff slab (₹8.50/unit for 500+ units/month) is significantly higher than the export rate, high-consumption homes benefit most when solar offsets their consumption directly — the "self-consumption" savings are worth more per unit than what you earn from export.
BESCOM allows a net metering connection up to your sanctioned load — the maximum electrical demand allowed by your connection. A typical residential LT connection of 5 kW allows up to 5 kW of solar. If you want to install more, you need to upgrade your sanctioned load first.
The general best practice is to size your solar system so that annual solar generation equals annual consumption. Generating significantly more than you consume results in unrecovered credits since BESCOM's year-end payout rate is lower than the effective self-consumption saving rate.
Consider a Bangalore homeowner consuming 500 units/month with a ₹4,000 bill. After installing a 5 kW solar system generating 650 units/month:
Result: A ₹4,000/month bill effectively becomes zero — or even a small credit — for 8–9 months of the year.
Indian farmers spend ₹50,000 to ₹2,00,000 per year on diesel and electricity to run irrigation pumps. Solar energy eliminates this cost permanently — and with PM Kusum subsidies covering up to 60% of the system cost, the investment pays back in just 2–4 years.
Agricultural pump irrigation is India's largest electricity consumer — accounting for roughly 18% of total electricity consumption. Yet farmers face two persistent problems: unreliable grid power (often limited to 6–8 hours per day in many districts) and rising diesel costs for pump sets when grid power is unavailable.
Solar water pumps solve both problems simultaneously. They generate power during daylight hours — exactly when irrigation is most needed — with no fuel cost, no dependence on the grid, and minimal maintenance.
The Pradhan Mantri Kisan Urja Suraksha evam Utthan Mahabhiyan (PM Kusum) scheme is a ₹34,035 crore programme to solarise 35 lakh agricultural pumps. Under Component-B (standalone solar pumps), farmers receive:
| Pump Size | Full Cost | After 60% PM Kusum Subsidy | Farmer Pays |
|---|---|---|---|
| 3 HP Solar Pump | ₹2.5–3.5 lakh | ₹1.5–2.1 lakh covered | ₹1–1.4 lakh |
| 5 HP Solar Pump | ₹3.5–5 lakh | ₹2.1–3 lakh covered | ₹1.4–2 lakh |
| 7.5 HP Solar Pump | ₹5–7 lakh | ₹3–4.2 lakh covered | ₹2–2.8 lakh |
| 10 HP Solar Pump | ₹7–9.5 lakh | ₹4.2–5.7 lakh covered | ₹2.8–3.8 lakh |
DC or AC solar pumps powered directly by panels. DC pumps are simpler and cheaper (no inverter needed) but limited to lower HP. AC pumps with solar inverters can run any standard agricultural pump. Both types are available in surface and submersible configurations for open wells, bore wells, and canals.
Combining solar with a small wind turbine ensures irrigation even on partially cloudy days and during early morning/evening when solar output is low. Particularly useful in Karnataka's coastal taluks and plateau regions.
Pairing solar pumps with drip or sprinkler irrigation systems reduces water use by 40–60% while enabling more frequent, precise irrigation cycles. Solar power and drip irrigation together can significantly increase yield and reduce input costs for horticulture farmers.
Off-grid solar systems for farm houses, equipment sheds, poultry units, and dairy operations — providing lighting, fans, refrigeration, and power tools without diesel generators.
Consider a farmer in Tumkur running a 5 HP diesel pump for 8 hours per day during the growing season (8 months):
Even for farmers on grid power paying ₹1.5–2/unit subsidised agricultural tariff, annual savings of ₹50,000–₹1.5 lakh are common.
Under PM Kusum Component-A, farmers can install ground-mounted solar plants on their land (up to 2 MW) and sell power directly to the DISCOM at a fixed tariff for 25 years — turning farmland into an additional income source alongside traditional crops.
Karnataka has one of India's most progressive solar policy environments — from KERC net metering regulations to PM Kusum implementation and the state's own MNRE top-up subsidies. Here is what it means for anyone installing solar in Karnataka in 2024–25.
Karnataka's renewable energy ecosystem is governed by multiple overlapping policies and regulators. Understanding which layer applies to your installation helps you maximise benefits and avoid compliance issues.
The Karnataka Electricity Regulatory Commission updated its net metering framework in 2023–24, reinforcing homeowners' rights to rooftop solar and grid connectivity. Key provisions:
Under KERC regulations, BESCOM is obligated to process your net metering application and install the bidirectional meter within stipulated timelines. If your application is delayed without reason, you can file a complaint with the KERC Consumer Grievance Redressal Forum.
Karnataka's state government released an updated New Energy Policy in 2024 targeting 10 GW of solar capacity by 2030. For residential solar, the key impacts are:
| Scheme | Applicable To | Benefit |
|---|---|---|
| PM Surya Ghar (Central) | Residential rooftop, all of India | ₹30,000–₹78,000 direct subsidy |
| Karnataka state top-up | Residential, through KREDL | Additional 10–15% on eligible systems |
| PM Kusum Component-B | Agricultural solar pumps | 30% central + 30% state = 60% subsidy |
| MSME solar scheme | Small businesses, service connections | SIDBI and state financing at preferential rates |
BESCOM (Bangalore Electricity Supply Company) supplies electricity to Bangalore Urban, Bangalore Rural, Chikkaballapur, Kolar, Tumkur, Ramanagara, and Chitradurga districts. If your property is in one of these districts, BESCOM is your DISCOM and the net metering application goes to them.
Other Karnataka districts are served by HESCOM (Hubli-Dharwad), GESCOM (Gulbarga), MESCOM (Mangalore), or CESC (Chamundeshwari) — each with similar net metering frameworks under KERC oversight. SunVana operates across all BESCOM and HESCOM areas.
Renewable Purchase Obligations (RPOs) require electricity distributors to source a minimum percentage of their power from renewable sources. Karnataka's RPO targets are among India's most ambitious, which means DISCOMs actively need rooftop solar consumers to count towards their targets. This regulatory pressure is one reason BESCOM is generally cooperative with residential solar applications — they need your system online as much as you do.
