Japan’s giant Sanyo Corporation, established in 1947, is a household name in the field of consumer electronic goods and domestic appliances. In 1975 the company branched out into the rapidly developing photovoltaic solar power generation market and soon after became the first company in to supply residential buildings in Japan with PV solar systems capable of generating energy that could be fed back into Japan’s power grid.
Driven by a commitment to environmental responsibility and to create sustainable energy sources, and backed by the financial resources of a global corporation, Sanyo’s investment in the research and development of PV solar module technology has kept them at the forefront of the PV solar power industry.
Sanyo’s experience and innovation in the field of PV solar power generation saw the initial manufacture, in 1997, of a new generation of PV solar panels featuring Sanyo’s patented HIT (Heterojunction with Intrinsic Thin-layer) technology. Offering greater light-to-power conversion efficiency and performance than any preceding PV solar panels, Sanyo’s ongoing development of HIT PV solar panels has seen the company break numerous solar cell efficiency records and win many environmental awards.
Sanyo PV Solar Panel Quality and Performance
Sanyo tests each of its PV solar panels rigorously, employing strict quality control measures to ensure that panel conforms to a wide range of international quality, environmental and health and safety regulations.
All of Sanyo’s PV solar panels are guaranteed to be lead-free and emission-free.
Constructed from resilient tempered glass and corrosion resistant black anodised aluminium frames, Sanyo’s PV solar panels are built to withstand adverse weather conditions such as heavy snow, gale-force winds and hailstorms. Sanyo’s confidence in the reliability of their PV solar panels merits a ten-year guarantee of product quality and workmanship.
Performance-wise, Sanyo’s patented HIT technology invests their PV solar panels with efficiencies comfortably in excess of industry-standards, and in some cases achieving industry-leading efficiencies of more than 20%. From a consumer point-of-view, the greater an individual PV solar panels’ efficiency, the fewer panels are required to generate the desired amount of electricity.
Sanyo PV Solar Panel Ranges
Sanyo’s ongoing investment in re-engineering and improving their PV solar panels means that their ranges are regularly updated. Sanyo PV solar panels are widely available throughout Europe and the UK, with PV solar panels for domestic and commercial installation most often supplied from the following ranges:
Slightly confusingly, HIT PV solar panels in Sanyo’s NKHE5 range have the prefix HIP. These panels are available with three different rated power outputs as follows:
HIP-205NKHE5 rated at 205 Watts
HIP-210NKHE5 rated at 210 Watts
HIP-215NKHE5 rated at 215 Watts
Each of these panels comprises 72 HIT solar cells and offers above industry-average panel efficiency at 16.3% for the 205 Watt panel, 16.7% for the 210 Watt panel and 17.1% for the 215 Watt panel.
Panels in Sanyo’s NKH range are uniformly black, including the anodised aluminium frame which gives them an aesthetically pleasing aspect.
NKH PV solar panels are guaranteed by Sanyo to produce a minimum of 90% of their rated power for ten years, and 80% of their rated power for twenty years.
New NSE range
Whilst Sanyo’s NKH range of panels is still widely available it will be superseded by the newer NSE range which features improved design, HIT technology and manufacturing processes to increase the rated power of each PV solar panel by 25 Watts without increasing the size of the panel itself.
Available in rated power outputs from 220 Watts to 240 Watts, Sanyo’s HDE range of HIT PV solar panels offered all of the benefits of the NKH range, but comprised a ‘honeycomb’ PV solar cell format which optimised the use of the panel’s surface and altered the dimensions of the panel, giving the consumer a choice between NKH and SDE panels depending upon the surface area available for panel installation.
As with the solar panels in Sanyo’s NKH range, the HDE panels had efficiencies ranging from 16% to 17%.
New HE range
Supplanting the HDE range, Sanyo’s new HE range launched in Europe in March 2011 and comprises HIT-H245E01, with an output of 245W and an efficiency of 17.7% and the HIT-H250E01, with an output of 250W and a module efficiency of 18.0%.
Indicative Sanyo PV Solar Installation Costs
The estimated cost of a 2.5kW domestic solar system, which should provide just over 40% of an average household’s electricity, using Sanyo HIT PV solar panels and fitted by an accredited MCS installer should cost between £12 and £14,000. A larger 4kW system using HIT solar panels would cost £16-17,000.
