Usage, or the slab?
Did the bill rise because you used more, or because you crossed into a costlier slab?
For homes
Understand why the bill feels high before you guess about solar.
The bill feels wrong, but the reason may be slab movement, a tariff change, an adjustment row, or a rooftop-solar question. BillTrends checks the bill for you, without asking you to become a tariff expert.
The worry
A high bill should not feel like a mystery.

The costly hours
Are time-of-day charges quietly making some hours cost more than you expect?
Is solar worth it?
Would a rooftop system actually pay back on your own tariff and your state's sunlight?
Is it for you?
Worth a proper read when the bill is big enough to matter.
Built first for businesses
BillTrends is made first for commercial and industrial connections, where demand, PF, ToD, tariff category and yearly usage patterns can move serious money.
When a home still gains
A home can still use it when the bill is large, the tariff has turned confusing, adjustments keep repeating, or rooftop solar is being weighed seriously.
What it will not do
It will not promise a universal home saving. It reads the bill, explains the charges, and keeps solar sizing tied to your real usage and roof.
What you'll see
Plain answers, with the source kept behind every number.
Why this bill is what it is
BillTrends compares your monthly bills, tariff category, slab movement, fixed charges, ToD rows and any unusual billing adjustments.
Whether solar is worth a serious look
The report estimates solar payback on your actual tariff and state yield, then shows payback years, NPV and IRR in plain language.
What to do next
You get a free preview with the full-year headline and one finding shown in full, then decide if the full report is worth it.
Every number, traced
No black box advice.
Kept honest, line by line
Every number in the report stays connected to the bill page and line it came from. That matters when a bill has a confusing adjustment, arrear row, subsidy treatment, or tariff change.
BillTrends works across Indian DISCOM bills, including MSEDCL, Adani Electricity, Tata Power, BESCOM, TNEB, TPDDL, BRPL, BYPL, PSPCL, GUVNL, and UPPCL.
About rooftop solar
Subsidy is policy. Payback is personal.
Subsidy is residential
PM Surya Ghar is a residential rooftop scheme with subsidy capped at 3 kW of system capacity, and a public promise of up to 300 units/month of free electricity for eligible households. Source: PM Surya Ghar, MNRE.
Payback needs your site
Rooftop payback should be built from your own bill and site yield, not one national number. PVWatts estimates output from size, location, tilt, azimuth, losses, and weather data. Source: NREL PVWatts.
Still wondering?
Home bill and solar questions.
Is BillTrends useful for a home?
Yes, when the bill is large, confusing, or linked to a rooftop-solar decision. BillTrends is built first for commercial and industrial connections, so the home use case is bill clarity and honest sizing rather than a promise of large savings.
Can it size home rooftop solar?
It can help estimate a sensible rooftop-solar size from your actual bill and expected site yield, then show payback as an estimate with assumptions.
Does the PM Surya Ghar subsidy apply to me?
It is a residential rooftop scheme with subsidy capped at 3 kW of system capacity. Commercial and industrial rooftop projects do not use PM Surya Ghar subsidy logic.
