Matched to actual consumption, then constrained by the usable roof area you know.

A Telangana tariff-aware estimate of system size, price, subsidy and savings—before you speak to an installer.
Free estimate·No phone number·Hyderabad & Telangana
Use open, mostly unshaded terrace area—not plot or built-up area.
Independent planning. Clear commercial role.
BHIMASEN helps you size, understand and compare the project. A registered partner surveys, contracts, installs and warrants it. If a completed installation earns us a referral or success fee, we disclose it.
The numbers that matter
A useful estimate should answer four questions.
We show the assumptions behind every number. The first estimate is immediate; roof and bill verification make it firmer.
A planning range after the current central subsidy—not a suspicious single-number promise.
Calculated with Telangana domestic slabs instead of pretending every unit costs ₹8.50.
Panels, inverter, structure, protections, approvals and service written down for comparison.
Before you accept a quote
Compare the scope, not the sales pitch.
“Tier-1 panels” and one price per kW are not enough. Make installers name exactly what you are paying for.

What happens next
From rough estimate to a defensible quote.
Check the bill and roof
Start with the number you have. Confirm usage, shade, access, cable route and sanctioned load later.
Put quotes on equal terms
Compare the same equipment, structure, approvals, exclusions, warranties and payment milestones.
Coordinate the project
The registered installer contracts and executes. BHIMASEN helps you track the details that get lost in sales talk.
Telangana bill mathematics
There is no honest flat rate for every home.
Telangana domestic tariffs select a category from total monthly usage and then apply its internal slabs. That changes the value of each solar unit you offset.
Read the official TGERC tariff orderWorked example350 units/month
- Energy charge
- ₹2,240
- Blended rate
- ₹6.40/unit
Before fixed/customer charges, duty and FSA. Those are excluded from the savings claim.
Straight answers
Before you book a survey.
No guaranteed zero bill. No invented government price. No pretending the first estimate is a final engineering design.
How is the subsidy calculated?
For eligible residential systems, ₹30,000 per kW applies to the first 2 kW and ₹18,000 to the next 1 kW. The maximum central subsidy is ₹78,000 for systems above 3 kW. Eligibility and compliant DCR modules still matter.
Does BHIMASEN install the system?
Not initially. A registered installation partner surveys, quotes, contracts, installs and provides warranties. BHIMASEN handles education, comparison, qualification and project coordination.
What if I do not know my usable roof area?
Leave it unknown. We first show a usage-matched estimate and the approximate roof area it needs. You can add a rough measurement later or confirm it during a survey.
What if I receive a Gruha Jyothi zero bill?
Tell the calculator. For an eligible home at or below 200 monthly units, present energy-charge savings are modelled at zero so we do not show a misleading payback claim.
