Terms & Conditions of Commercial Service
Comprehensive contractual guidelines governing platform engagement, digital engineering estimations, equipment procurement, UPCL net-metering liaison, and turnkey solar EPC execution across Uttarakhand.
Agreement Notice: By accessing the Kumaun Solar digital portal (https://solar.kumaun.in), engaging our engineering calculators, or executing a physical solar engineering procurement and construction (EPC) contract, you agree to be bound by the terms, engineering covenants, and jurisdictional stipulations outlined herein.
1. Engineering Calculations, STC Baselines & Field Yield Caveats
All solar generation models, financial payback projections, and energy yield calculators presented on Kumaun Solar are computed utilizing standard international testing baselines (Standard Test Conditions: 1,000 W/m² solar irradiance, 25°C cell junction temperature, air mass AM 1.5 spectral distribution).
Users acknowledge that real-world electrical generation across Uttarakhand varies based on high-altitude microclimates, ridge shadow casting, local cloud density during monsoons, module tilt angles (typically 28° to 32° south-facing in Kumaun), dust accumulation, and sub-zero winter temperatures. Estimates generated via web tools are for preliminary feasibility purposes and do not represent a guaranteed contractual generation volume unless specifically underwritten in a formal Performance Ratio (PR) guarantee agreement following a physical engineering audit.
2. Quotation Validity & Physical Engineering Feasibility Survey
Digital quotes generated through our automated calculators are preliminary estimates valid for thirty (30) calendar days. Final binding EPC project contracts are subject to a physical structural and electrical site assessment conducted by Kumaun Solar engineers to verify:
- Roof slab load-bearing capacity, column tie-in points, and anchoring substrate integrity (RCC slab vs pre-engineered building sheet).
- Existing electrical distribution board (LT panel) health, busbar capacity, and earth pit impedance (maximum 2 ohms permissible).
- UPCL local distribution transformer (DTR) solar hosting capacity as mandated by the Uttarakhand Electricity Regulatory Commission (UERC).
- Actual DC cable run length between the rooftop array and the ground/basement inverter station to limit DC voltage drop below 1.5%.
3. Commercial Pricing, Taxation & Payment Schedules
All commercial solar quotations are denominated in Indian National Rupees (INR). Unless explicitly stated otherwise, turnkey project pricing includes:
- Supply of Tier-1 ALMM List-I compliant photovoltaic modules (e.g. Tata Power Solar, Waaree, Adani, Vikram Solar) and BIS-certified smart inverters.
- Hot-dip galvanized (HDG) mounting structures with minimum 80-micron zinc coating designed to withstand wind gusts up to 160 km/h in accordance with IS 875 (Part 3).
- Standard electrical Balance of System (BOS) components: 4mm²/6mm² solar DC cables (EN 50618 certified), IP65 DCDB/ACDB with Type-II surge protection devices (SPDs), dual chemical earth pits, and lightning arresters.
- Applicable Goods and Services Tax (GST) computed at statutory rates (concessional composite rate of 12% on solar power generating systems under HSN 8461 / 9954 or applicable split valuation rules, subject to current Central Board of Indirect Taxes and Customs notifications).
4. UPCL Net-Metering & Statutory Approvals
Kumaun Solar acts as the facilitating EPC contractor for processing bidirectional net-metering applications with Uttarakhand Power Corporation Limited (UPCL). However, the ultimate grant of net-metering connectivity and timeline for bidirectional meter installation is governed by UPCL divisional jurisdiction and transformer capacity constraints.
The client is responsible for providing legitimate electricity consumer records, ensuring zero outstanding electricity bill arrears, and maintaining an active sanctioned load commensurate with the proposed solar system capacity. Where UPCL mandates a sanctioned load enhancement prior to solar synchronization, all DISCOM-levied load enhancement fees and security deposits remain payable directly by the consumer to UPCL.
5. Central & State Government Subsidies (PM Surya Ghar)
Government subsidies under the PM Surya Ghar Muft Bijli Yojana (up to ₹78,000 for residential systems up to 3 kW) are disbursed directly by the Ministry of New and Renewable Energy (MNRE), Government of India, via Direct Benefit Transfer (DBT) into the applicant's Aadhaar-linked bank account.
Kumaun Solar ensures 100% equipment and installation compliance—including mandatory deployment of Domestic Content Requirement (DCR) solar cells and ALMM-listed modules—and assists in uploading the Joint Commissioning Report (JCR). However, Kumaun Solar does not issue cash subsidies directly, cannot deduct the subsidy value from the upfront EPC invoice in advance of Central release, and bears no liability for delays resulting from national portal server downtimes, Aadhaar mismatch rejections, or banking verification lags.
6. Equipment Warranties & Manufacturer Pass-Through
All primary equipment installed by Kumaun Solar carries direct warranties from original equipment manufacturers (OEMs):
- Solar PV Modules: 10 to 12 years of comprehensive manufacturer product warranty covering manufacturing defects, and 25 to 30 years of linear power output warranty guaranteeing minimum 80% to 87.4% rated output at Year 25/30 depending on cell chemistry (Mono PERC vs TOPCon).
- Solar Grid-Tie Inverters: 5 to 10 years of standard manufacturer warranty covering electronic components, MPPT trackers, and communication cards.
- Workmanship Guarantee: Kumaun Solar provides a 1-year comprehensive workmanship and installation guarantee covering structural bolt integrity, rooftop waterproofing sealants, DC cabling crimps, and grounding terminations.
7. Force Majeure & High-Altitude Weather Hazards
Neither party shall be held liable for failure or delay in performance caused by circumstances beyond reasonable control, classified as Force Majeure events. In the Himalayan terrain of Uttarakhand, Force Majeure explicitly includes severe cloudbursts, unprecedented snowfall exceeding structural design limits, geological landslides, road blockages along mountain highways (NH-109, NH-9), earthquakes, lightning strikes exceeding IS/IEC 62305 protection ratings, civil unrest, or statutory embargoes.
8. Governing Law & Exclusive Legal Jurisdiction
This agreement, including all digital interactions, technical quotations, and physical EPC contracts executed by Kumaun Solar, shall be governed by and construed in accordance with the substantive laws of India. Any legal dispute, arbitration proceeding, claim, or controversy arising out of or related to these terms shall be subject to the exclusive jurisdiction of the competent civil courts situated in Haldwani / Nainital, Uttarakhand, to the exclusion of all other courts.
9. Frequently Asked Commercial Terms Questions
What happens if UPCL rejects my solar net-metering application due to transformer capacity?
Under UERC regulations, rooftop solar capacity on any distribution transformer is capped at 80% to 100% of transformer rated capacity. In the rare event that UPCL confirms zero transformer capacity headroom, Kumaun Solar provides alternative engineering options: (a) applying for a zero-export system with a reverse power relay, (b) reconfiguring the system to an off-grid or hybrid energy storage configuration, or (c) assisting in filing for a transformer capacity enhancement request with UPCL.
Who is responsible for rooftop waterproofing during solar mounting installation?
Kumaun Solar utilizes specialized non-invasive anchoring mechanisms where possible. For RCC roofs requiring chemical anchor fasteners, our installation crews use high-grade polymer/bituminous waterproofing sealants around every drill hole to prevent water seepage. For industrial tin roofs, non-penetrating standing seam aluminum clamps are deployed, eliminating roof punctures completely.
Can the quoted project price change after the physical rooftop survey?
Standard website estimates cover standard installations (cable distance up to 30 meters, standard 1-meter elevated structure). If a client's site requires custom engineering—such as a 10-foot elevated super-structure for rooftop terrace usability, crane lifting in narrow hill terrain, or exceptionally long cable runs exceeding 50 meters—the quotation is revised transparently with bill-of-materials cost breakdowns before contract signing.
How is warranty service handled if a module or inverter experiences failure?
As an authorized engineering partner, Kumaun Solar assists in dispatching warranty claims directly to the OEM’s regional service center in Uttarakhand. We conduct on-site electrical diagnostics (open-circuit voltage Voc and short-circuit current Isc testing), document serial number logs, and facilitate rapid replacement under the manufacturer’s product warranty policy.
