250 Watt Mono Solar Panel - Half Cut HPBC - 157 cm x 77 cm

Panels and Kits ship from $0 (Auckland central) to $29.99 (rural South Island). Adding a Battery increases shipping costs due to heavy and dangerous goods classification.

Orders are shipped Mondays to Fridays and take on average 1-3 working days to arrive.

Orders received before midday will be shipped same day.

At LUX Solar we only source monocrystalline panels as they offer the highest efficiency. Monocrystalline panels are manufactured from a single rod of silicon thus the crystal structure inside the silicon is uniform, with very few impurities. Polycrystalline panels on the other hand are made up of smaller crystal structures that introduce grain boundaries in each solar cell. This causes inefficiencies in the conduction of electrons due to defects associated with the crystal boundary.

HPBC (Hybrid Passivated Back Contact) solar cells, are the latest solar technology that introduces unobstructed front shading by metal contacts. This pioneering approach optimizes photon collection, resulting in enhanced conversion efficiency. The HPBC cell sets a new industry standard, significantly enhancing light absorption and photovoltaic conversion capability, resulting in substantially improved module power output.

The result is panels capable of generating more energy under higher temperatures and lower light. Some studies have shown that that HPBC cells can produce output up to 10% higher under the same conditions as PERC products.

Busbars conduct the power generated by solar cells when they are hit by photons. 5BB means there are five busbars in each solar cell. 10BB mean there are 10 busbars in each solar cell. Back in the day, solar panels used to have only 2 busbars, but as technology evolves, the solar industry has been increasing the number of busbars in solar panels, to reduce internal resistance losses and increase cell efficiency.

Half-Cut also known as half-cell technology, means silicon solar cells that have been cut in half using a laser cutter. This helps reduce power loss from resistance, lowers the operating temperature of the panels, reduces hot spot temperature by 10~20°C, and improves the panels' overall performance in partial shade.
