SANYO HIT Solar Panels: higher efficiency through hybrid technology
-SANYO HIT Solar Cells-
HIT cells are SANYO’s signature solar pv technology. They are a hybrid technology that combines monocrystalline silicon with amorphous silicon–two common cell types in the PV industry–into one for high-efficiency, heat-tolerant cells. The SANYO website describes the panels as “the most technologically-advanced solar panels in the world”, owing in great part to their hybrid nature, which is unique to SANYO.
-HIT-N235SE10 Solar Module Key Attributes and Points of Difference-
-One of the highest conversion efficiencies (sunlight to electricity) in the world: up to 21.1% solar conversion efficiency, 18.6% module efficiency, compared to efficiencies of 13-14% among conventional crystalline modules. Advances in efficiency relative to SANYO’s other HIT panel model (HIP-210NKHE6) are thanks to two changes to the technology: 3 tabs as opposed to 2 (minimising electrical losses in cell fingers), and anti-reflection coated glass (reducing losses from reflection and scattering of sunlight, thereby capturing more light).
-Thanks to higher efficiency, panels are 20% smaller than most panels of similar rated output: ideal for those with limited roof space looking to maximise their power production.
-SANYO’s HIT solar cells are also made at a lower temperature than traditional cells, requiring less energy and materials to produce for a more environmentally-friendly manufacturing process.

-Product Specifications/Electrical Characteristics-
You can compare how SANYO HIT panels compare to a number of other name brand panels on the Desert Knowledge Australia website, an invaluable resource for those shopping around for solar panels.
-Other products by SANYO-
-SANYO’s other HIT panel model is the HIP210NKHE6, a 210kW panel which, although more cost-effective, has a slightly lower solar conversion efficiency of 16.7% (solar efficiency of 18.9%).
-Sanyo also offers a 230W multicrystalline panel (MP6-230E01) with a module conversion efficiency of 14.1%.
-Component standards met/awards-
All three models of Sanyo panels are certified by the Clean Energy Council (CEC) of Australia, and are on the list of CEC-approved components.
25 year performance warranty
5 year workmanship warranty
(Your installer may also offer additional warranties for the entire system.)

SANYO HIT solar photovoltaic cells are manufactured in Japan.
-History in the Industry-
-Quote from Bill Crichton President/Managing Director of Sanyo Oceania-
SANYO have more than 30 years experience in solar technology and we are confident our new 235 watt solar panel is amongst the best and most reliable in the market. The new panel is capable of producing more electricity per panel than our previous models, which ultimately means bigger savings for our consumers “ it will reduce payback periods and this is critical now with reduced Government incentives.
Solar Choice is a solar installation comparison service: we don’t undertake our own solar array installations, but we do offer free independent solar quote comparisons of what’s on offer from trusted solar system installers nationally. Our installers may use components from different manufacturers, and if you’re new to solar power installations, you will probably want to know what distinguishes one company’s panels, inverters, batteries, and other system parts from those of their competitors. This article is one of a series written to help you make an informed decision about purchasing your solar power system.
