Solar Panels

Solar Modules (Panels.)

Solar panels are referred to in the trade as solar “modules” and trying to separate fact from fiction, with regards to performance and quality of build can be quite overwhelming. This problem is compounded by salesman quoting/showing lists from trade magazines, however there is no industry recognised legitimate list available that we are aware of that rates the various modules for their performance in Scotland/Northern Hemisphere. “Efficiency” of a module is also often referred to as a form of measuring performance, but this is a fallacy, as “efficiency,” in simplistic terms, is a measure of the ability of one square meter of the module to convert light to electricity at a set irradiance, temperature, angle to the sun etc. etc. but at the end of the day a 250W module is a 250W module (but they may vary in size.) There are a multitude of solar modules (panels) on the market today, the majority of which come from China, but are disguised with names such as “Canadian Solar” ( which is a good module, recommended by us, but manufactured in China not Canada) to try and give the impression that they are manufactured in a different country. Other module manufacturers base their operations in European countries such as Norway, and again give the misleading impression that they manufacture the modules there, but again they come from China or Taiwan.
In general terms, European and U.S.A. manufactured modules are, on the whole, well manufactured and produce a high yield, but there are also modules manufactured in the far eastern countries that are also robustly built, high yielding and perform well in low light conditions – it’s just a case of knowing which ones they are.
There are 3 types of solar modules available.

Monocrystalline, Polycrystalline and Thin Film. The two most appropriate for the U.K. market are the Monocrystalline and the Polycrystalline.

Monocrystalline modules perform better than polycrystalline modules (the difference however between the two is marginal.) Monocrystalline panels are black, whereas polycrystalline tend to be a blue/silver colour. Therefore it is recommended that you choose a monocrystalline module (black) should you be taking aesthetics into consideration as it is the better looking panel.

This is a very fast evolving industry, and the advances in solar technology in the past 2 years have been incredible.

We are constantly monitoring these advances along with the Scottish Institute for Solar Energy Research, in order to seek out the best performing, value for money modules, both monocrystalline and polycrystalline available in Scotland today.  We also consider build quality in the decision making process as well as availability. Availability, in the present climate leading up to January, is become a major factor.

We can supply any modules on the market today, including household names such as Hyundai and Sharp. However, as explained above, and in order to simplify the decision making progress we recommend the modules listed below. All the following modules (except the .833 Gallium or the .833 Eternity which improve on this) come with a 25 year performance warranty (will not fall below 80% power output over this time) and have 12 years manufacturer’s warranty (this is a warranty against discolouration etc.) The important one is the performance warranty as this guarantees the panels working for the duration of the warranty.

Suntellite Panels

The Suntellite photovoltaic modules are manufactured using state of the art production lines from China. All models use TUV and UL certified components.
Power output from the panels is guaranteed to be not less than 90% of minimum rated power for a period of 10 years from the date of purchase AND not less than 80% of minimum rated power for a period of 25 years from the date of purchase.

Monocrystalline Modules

solar-worldSolarworld Black 250W

These are manufactured in Germany & USA to a very high standard,  and are most definitely of the best “build” quality that we have worked with. As a result they tend to weigh 3 kg more than the average modules and are in essence over engineered for your average domestic install, but they are undoubtedly the best quality module on the market today. These modules are well known and highly acclaimed within the industry, as they have a good historic record and are subjected to rigorous quality and performance tests prior to leaving the production line.

 

 

 

8338•33 Gallium Black

Relatively new to the Scottish market, and sold by a Spanish Company who manufacture them in Taiwan. Difficult to prove as these have not been on the market very long and do not have the proven history of the Solarworld modules but are guaranteed to operate at 95% efficiency for the first 12 years and not falling below 90% over 25 years – this is because the silicone cells are coated in Gallium and do not start degrading until after 12 years.

The only “downside” is that we feel that micro-inverters are going to dominate the inverter market, but due to the cell configuration of the Gallium module they cannot be used with micro-inverters, which may see production stop in the future.

8•33 Eternity Premium Black

This is new to Scottish market, but has been used since the middle of last year in England & Wales and has proven popular. It has the same performance guarantee as the Gallium and in “flash tests” all the modules produce @ 260W but are rated at 250W. This module can be used with micro-inverters.

L.G. 300W Black Mono

We have used these panels in installations where maximum power per m² is paramount. L.G. are a household name and these modules do perform well with the new Enphase M250 micro-inverter. We have installed this combination in both the west and east coast of Scotland – and to date all are performing extremely well. Downside however is that the cost per watt to buy does make this one of the most expensive modules on the market,

Suntellite Panels

Power output from the panels is guaranteed to be not less than 90% of minimum rated power for a period of 10 years from the date of purchase AND not less than 80% of minimum rated power for a period of 25 years from the date of purchase.

We have used these modules on various projects, and in various locations throughout Scotland, and through monitoring their performance using Enphase, we have found to date, that they perform well in all conditions, including low-light.

Polycrystalline Modules

Canadian Solar

canadian-solar

We do not have the statistics to back this statement – but most probably the most used polycrystalline module in Scotland – good build quality and low light generation. – as an alternative we can also offer a Risen (German made) module at this price.

Module Warranty

All the above modules come with the following manufacturer backed warranties:

Canadian solar – 10 year product & 25 year performance.

833 – 12 year product & 25 year performance.

Solarworld – 10 year product & 25 year performance

L.G. – 10 year product & 25 year performance
