1. Acceptance of terms
By accessing or using free-solar-calculator.com (the "Site"), you agree to be bound by these Terms & Conditions. If you do not agree with any part of them, you must not use the Site.
2. About the service
The Site provides free, ungated calculators and informational content related to rooftop solar in India — including plant sizing, subsidy estimation under PM Surya Ghar, savings and ROI projections, loan EMI comparisons, and state tariff data. The service is provided on an "as is" and "as available" basis. No account, registration, or fee is required.
3. Informational purpose only — not professional advice
All outputs are indicative estimates generated from public reference data (MNRE benchmark costs, solar irradiation data, average DISCOM tariffs, typical performance ratios, and prevailing lending rates). Nothing on the Site constitutes financial, investment, legal, tax, or engineering advice, and nothing is a quotation, contract, or offer of any product or service.
Before making investment, purchasing, or loan decisions, consult a licensed solar installer, your DISCOM, your bank, or other qualified professionals.
4. Accuracy of information
We strive to keep subsidy slabs, benchmark costs, tariffs, and sun-hour data current, but:
- Government schemes, MNRE benchmarks, and DISCOM tariffs change frequently and vary by state, consumer category, and date.
- Actual generation depends on shading, orientation, tilt, soiling, equipment choice, and weather.
- Loan rates offered by banks differ from the rates used in our EMI model.
- We do not warrant that any information on the Site is complete, accurate, or up to date at all times.
5. Your responsibilities
You agree to use the Site only for lawful purposes and in accordance with these terms. You must not:
- Use the Site in any way that violates applicable Indian law or regulation.
- Attempt to gain unauthorized access to the Site, its servers, or any related system.
- Introduce malware, scrape the Site at unreasonable volume, or interfere with its normal operation.
- Reverse engineer, resell, or republish the Site's calculators or content as your own service without written permission.
- Misrepresent the Site's outputs as certified engineering or financial reports.
6. Intellectual property
Unless otherwise stated, the Site's design, text, logos, graphics, and original calculators are owned by or licensed to free-solar-calculator.com and are protected by applicable intellectual property laws. Government scheme names, subsidy figures, and factual reference data are in the public domain. You may view, print, and share links to our pages for personal and non-commercial use; you may not reproduce substantial portions of the Site commercially without prior written consent.
7. Third-party links
The Site may link to government portals (MNRE, PM Surya Ghar, state DISCOMs), banks, or other third-party websites for reference. We do not control and are not responsible for the content, accuracy, or privacy practices of those sites. Visiting them is at your own risk.
8. Limitation of liability
To the maximum extent permitted by law, free-solar-calculator.com and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising out of or in connection with:
- Your use of, or inability to use, the Site.
- Reliance on any estimate, subsidy figure, or projection produced by the calculators.
- Decisions made on the basis of the Site's output, including purchase, installation, or loan decisions.
Where liability cannot be excluded, it is limited to the greater of the amount you paid us (which is zero, as the service is free) or ₹1,000.
9. Indemnity
You agree to indemnify and hold harmless the Site's operators from any claims, damages, or expenses arising from your misuse of the Site or your violation of these terms.
10. Changes to the Site and to these terms
We may modify, suspend, or discontinue any part of the Site at any time without notice. We may also update these terms; the "Last updated" date above will reflect changes. Continued use of the Site after changes constitutes acceptance of the revised terms.
11. Governing law & jurisdiction
These terms are governed by the laws of India. Any disputes arising out of or relating to the Site or these terms shall be subject to the exclusive jurisdiction of the courts in India, without prejudice to consumer rights available under applicable law.
