Agrivoltaics combines photovoltaic electricity generation with continued agricultural activity on the same land. A vertical-mount (east–west facing) agrivoltaic configuration using 720 W bifacial modules is one of the standard layouts cited by research institutes for low-shade, high-land-equivalent-ratio (LER) installations.
The scenario model uses a single per-kWp CapEx midpoint of USD 330 on a consistent undiscounted basis, applied in Year 0. The breakdown below shows the composition of that midpoint for transparency; the model does NOT sum line-item midpoints separately — only the headline USD 330 / kWp feeds the TCO tables. All values are illustrative.

HS national line and applicable rates MUST be confirmed on the Tanzania Revenue Authority (TRA) official tariff portal before any commercial quotation. Tradvolt does not hardcode duty rates. The TCO model on this page uses an ex-duty/ex-VAT CapEx midpoint of USD 330 / kWp pending lookup; per-unit landed cost will change once the duty/VAT stack is applied.

Other datasheets and OEM-issued certificate copies (specific 720 W SKU datasheet revision, K2 Systems mounting manual revision, IEC/CE certificate PDFs) are released against an open RFQ. Submit the form below to request the latest OEM-issued revisions.
By submitting you agree to be contacted by Tradvolt regarding this RFQ. Indicative quotations are non-binding and subject to OEM confirmation, freight schedule and HS/duty verification on the TRA tariff portal.
1. What is the indicative landed-cost range for a 720W agrivoltaic system in Tanzania?
Using the model assumptions on this page (per-kWp CapEx midpoint USD 330, 25-year horizon, 8% discount rate), the scenario model returns NPV = USD 693,867, IRR = 27.90%, simple payback 3.641 yr, discounted payback 4.471 yr and LCOE USD 0.0376 / kWh. Per-module landed cost requires confirmation of the TRA duty/VAT stack.
2. Is a 720W panel suitable for vertical agrivoltaic mounting?
Bifacial 720 W dual-glass modules in the JinkoSolar Tiger Neo N-type class (family SKU JKM720N-78HL4-BDV) can be deployed in vertical east–west orientation. Confirm mechanical load, torque, clamping and voltage limits with the OEM installation manual revision before final design.
3. Which certifications should a 720W panel carry for the Tanzanian market?
The minimum credible documentation set is IEC 61215-1:2021 (design qualification) plus IEC 61730-1:2016 and IEC 61730-2:2016 (safety qualification), with a CE Declaration of Conformity under Regulation (EC) 765/2008. Verify exact certificate numbers and issuing bodies directly with the OEM before shipment.
4. What HS code applies to 720W solar panels imported into Tanzania?
PV cells and modules are classified under WCO Harmonized System chapter 8541 (photosensitive semiconductor devices, including photovoltaic cells). The exact Tanzania national line and applicable duty/VAT must be confirmed on the TRA tariff portal before quotation.
