Import 90w Polycrystalline Solar Panel (Mac-Psp090) — Buy in wholesale FOB from Supplier in China

The MAC-PSP090 is a 90W polycrystalline photovoltaic module manufactured by Macsun Solar Energy Technology Co.,Limited in Shenzhen, China. It uses multi-crystalline silicon cells with a power rating of 90 watts, suitable for low-voltage DC systems and small-scale solar arrays. The panel features a compact, lightweight form factor that simplifies mounting on residential rooftops, RVs, remote monitoring stations and portable power kits. Macsun lists this unit for residential and commercial energy projects, though buyers should confirm the exact voltage at maximum power (Vmp) and open-circuit voltage (Voc) with the supplier before system design.

Polycrystalline silicon is formed by melting raw silicon and casting it into square ingots, which are then sliced into wafers. This manufacturing route yields slightly lower cell efficiency than monocrystalline alternatives, but it reduces material cost and performs better under diffuse light and elevated temperatures. The MAC-PSP090 uses standard tempered glass fronting and an anodised aluminium frame, typical for this product class, with a junction box rated for outdoor exposure. Buyers should verify the backsheet material (TPT or TPE), frame thickness, and whether the cells are 156mm x 156mm or 166mm x 166mm format, as this affects array string sizing and mounting compatibility.

Typical applications include 12V battery charging, solar home systems, street lighting controllers, telecommunications relay stations and agricultural pumping where grid extension is uneconomical. The target buyer is an importer or EPC contractor serving emerging-market rural electrification programmes, or a distributor of caravan and marine electrical goods. Macsun offers the MAC-PSP090 with flexible MOQ for bulk supply, but the exact minimum quantity, lead time and Incoterm options are not stated in the listing data. Buyers should request a proforma invoice specifying packing (typically 2 panels per carton with corner protectors), pallet dimensions and total container load capacity to optimise freight costs.

Macsun Solar Energy Technology Co.,Limited is registered in Dalang, Longhua District, Shenzhen, Guangdong Province, postal code 518108. The supplier holds a Harbor trust tier on the marketplace, which indicates a baseline verification level rather than advanced audit status. The response rate is shown as 0.00% with an average response time of zero hours, suggesting that either no enquiries have been logged or response data has not been transmitted to the platform. Buyers should treat this signal cautiously and initiate direct contact to gauge communication reliability before committing to an order.

The company profile visible in this listing does not state a year of establishment, factory floor area, annual capacity, number of employees, revenue figure, or named client references. It does not list specific certifications such as IEC 61215, IEC 61730, UL 1703 or MCS accreditation for the MAC-PSP090 module. Buyers should request copies of test reports, factory audit documents and a current certificate of conformity rather than assuming compliance. Macsun positions itself as a supplier of residential and commercial solar energy hardware; the extent of its in-house cell manufacturing versus module assembly is unstated and should be clarified during due diligence.
