No jargon, no fluff. Just what Bengaluru homeowners actually need to know about rooftop solar, PM Surya Ghar, and BESCOM.
What to find on your BESCOM bill once net metering starts: imports, exports, carried-forward units and fixed charges, plus a simple monthly check and an illustrative example.
Whether a metal sheet, asbestos-cement or tiled roof can carry rooftop solar, how panels are fixed, who answers for leaks, and what to get in writing before you sign.
An illustrative staged payment schedule, what to verify before each payment, how loans and subsidy fit in, and the red flags that mean walk away.
Who should apply when the roof and the BESCOM connection belong to a landlord, how to split cost and savings with an illustrative check, and what to agree in writing.
What the DC to AC ratio means, when clipping costs you real units, an illustrative loss check, and the questions to ask a vendor about the inverter on your quote.
Which loads (washing machine, pump, geyser) can move into daylight hours, what to leave alone, an illustrative saving check, and a simple weekly routine to get more from your rooftop system.
What a battery adds that net metering cannot, what it costs, a rough illustrative value test, and a checklist before you pay for storage.
Three datasheet numbers to compare, a simple payback test for any panel premium, and two checks (subsidy eligibility and warranty backing) that matter more than the cell type.
A quote tells you the kW, not what is left of your terrace. How to plan walkways, tank and cleaning access, drain outlets and raised versus low structures before the installer starts.
An EV adds a steady load to your BESCOM bill. How to estimate the extra units, think through day versus night charging under net metering, and check your load and wiring before buying a charger.
Warranties are written around manufacturing faults, not outside events. Questions to ask your home insurer about rooftop solar, who carries risk during installation, and the claim file to build now.
Quotes list panels and inverters, but earthing and surge protection often get one vague line. What earthing, lightning arrestors and surge protection devices do, and what to get in writing before you sign.
Panels lose a little output every year, but most savings tables assume a flat line. How to read the performance warranty, what degradation does to 25-year savings, and how to tell normal ageing from a fault.
A system can run for months with a fault and nothing looks wrong. A monthly routine using your inverter, the app and your BESCOM bill to spot low output early, and when to call your installer.
The same kW can mean very different scope, equipment and after-sales. A seven-point way to line up rooftop solar quotes: inclusions, DCR proof, subsidy handling, BESCOM support, warranty and payment terms.
Your panels will sit on your roof for decades. Why old waterproofing should be redone before installation, what to ask about the mounting structure, and who should be responsible if a fixing point leaks.
Claiming the PM Surya Ghar subsidy means DCR panels: Indian cells and Indian modules, not just an Indian brand name. What DCR means, how quotes hide the gap, and what to get in writing before you pay.
A water tank, a coconut tree or a parapet can cost a rooftop system more output than its size suggests. How shading works, how to spot it before you sign, and what to ask your installer.
KERC's April 2026 true-up order adds 56 paise per unit to every BESCOM bill through April 2027. What the charge is, why it recurs, and what it actually does to your rooftop solar payback math.
Collateral-free rooftop solar loans let you install with little to nothing from savings — but the EMI math only works if you understand how the loan and the subsidy actually sequence. Real numbers, and where it goes wrong.
Installer quotes average your generation across 12 months, but June-September cuts output by a quarter or more. Why the monthly curve — not the annual number — should drive your sizing and payback math.
BESCOM's net metering agreement is tied to your consumer number, not your rooftop. What happens to the agreement, your banked export credits, and warranty paperwork when a solar home changes hands — a checklist for both sellers and buyers.
Installation isn't the finish line — BESCOM's commissioning inspection is. The document checklist, site inspection process, and common rejection reasons that delay connections by weeks.
KERC's tariff order lets BESCOM consumers install solar at one site and credit the generation against a different connection's bill. What virtual and group net metering actually allow, and who it helps.
Net metering banks your surplus units month to month — but at year-end, unused credits settle at a fraction of retail value and don't carry forward. Why this changes how big a system is actually worth building.
Your roof isn't what caps your solar size — your BESCOM sanctioned load is. Why a bigger system often needs a load enhancement first, and what that costs every month, forever.
If you're already getting 200 free units a month, the usual solar savings pitch doesn't apply the way installers present it. How the 200-unit cliff changes system sizing and where solar still saves real money.
Your panels are warrantied for 25 years, but your inverter usually isn't — and it's the part most likely to fail first. What's covered, what voids it, and whether extended warranty is worth it.
Dust, construction grit, and monsoon silt quietly cut into your output. How much generation you're losing, how often to clean in Bengaluru's conditions, and what's safe to do yourself.
Rooftop solar for flat and apartment owners in Bengaluru — what BESCOM allows, how society approval works, shared roof rights, and when it actually makes financial sense.
Picking an installer who isn't on the PM Surya Ghar / BESCOM empanelled vendor list can forfeit your subsidy entirely. How to verify empanelment and red flags to check before signing.
Most homeowners assume solar means backup power during an outage. It doesn't — unless you plan for it. Why grid-tied systems shut off, and what it means for your ROI.
Complete eligibility criteria, required documents, step-by-step application process, and how much subsidy you'll get for each system size.
What is net metering, how does BESCOM calculate your bill after solar, and what happens to excess power you generate? With real examples.
A simple guide to sizing your rooftop solar system based on your BESCOM bill, roof space, and energy usage patterns.
