Wild Rose Emu Ranch Solar Electric System

You will often find Clover Quinn at the Hamilton Farmers Market on Bedford St from 9:00 – 12:30 on Saturdays in the summer.  Clover is very excited about her solar electric system.  “Last month our electric bill was $50.04.  That includes the base rate of $46.00.” Clover smiles,  “Who would have dreamed we would eagerly await our electric bill in the mail.”

Micro Inverters versus SolarEdge

 

SolarEdge Inverter

Micro Inverters versus SolarEdge and why we do not use Micros anymore.
Nine years ago, Enphase Corporation from California introduced one of the first viable micro inverters and it was a big deal. The advantages were huge as no longer did we need to have long strings of 10 modules that suffered greatly when only one was shaded or covered with snow. As well we could now look at the production of each individual module and easily identify an issue. The monitoring was easy to employ with a simple data cable which transmitted production data to a website keeping track of production. Before this detailed monitoring was an expensive option.
That was nine years ago, a lifetime in this industry. Enphase upset the domination of several European manufactures who owned the world-wide inverter market. Several of these companies came out with there versions of micros. One Swiss company jumped into micros and a couple of years later discontinued this offering.
This was telling as one of the major questions of utilizing a microinverter is where it is placed. Micros sit behind the solar module in a hostile environment. Here in Western Montana we know that a summer day can start in the cool 40’s and end up in the 90’s. And up on your roof high afternoon temps are even more extreme. This a big temperature change for the electronics to tolerate on a daily basis.
Other parts of the planet do not see this extreme variation and this is less of a factor. However, the manufactures claim a 25 year warranty. The big question is will these electronics last as claimed. In our experience it is common to see a company with grand claims disappear with insolvency or reorganization saying goodbye to long term liabilities like warranties.
SolarEdge steps in and changes the Inverter world once again.
This inverter system is the next step in the evolution of the inverter. SolarEdge took the advantages of Micros and said goodbye the largest disadvantage of where the electronics do their job. By taking the bulk of the electronics and placing them on a protected wall or even better in a utility space, this reduces the operating temperatures and gives us a longer useful life. A small optimizer with much simplified electronics is placed behind the module and provides all the benefits of micros such as individual module level monitoring.
These inverters operate at an amazing 99% efficiency and have swept the grid tied solar market with a dominate hold of the world inverter market.
We have 450 micros out in the field and we can see some applications for this product yet SolarEdge remains our go to inverter technology.

Why we use SolarWorld and L.G. Solar Panels

We are picky when it comes to who’s modules we use. After three decades of working with a good number of manufacturers we developed two main criteria which dominate our selection process. Number one is a company which has staying power. We have seen too many companies come and go, leaving us with a long-term warranty with no one to support the product. A 25-year module warranty is standard in the industry. You cannot operate as a module manufacture without it, whether or not the company will be there. Bankruptcy clears long term commitments unless the company takes actions to cover their warranties.
Number two qualification is a track record of standing behind their product and the companies brand. The two companies we work with are just plain proud of their product. It helps when you talk to workers on the factory Floor who when queried tell me this is the best job they have ever had and you can feel this is more than just a job.
This is why we work with SolarWorld of Hillsboro, Oregon and L.G. from South Korea. Both companies have been around the solar block, have a high-quality product which they are committed to support for the long run.

What module wattage is best and why we work with high power 355 watt or higher modules.
It’s simple really, the more power per module the less space it requires on your roof or mount structure. Lower wattages, especially below 295 watts, cost less yet this cost savings is lost as we need to install more modules to achieve the same total array output. More individual modules increase the number of mounting structure material, optimizers and installation time and costs.
Companies leading the industry put much energy into maximizing cell efficiencies. There are hundreds of solar module manufactures around the world. Like many products today, it is a buyer beware world.

Solar Electric Rail Mount Installation

These photos show the flush mounting system with the rails and attachments before the solar modules are set in place. A south facing roof plane is the most productive yet we also adapt to various roof designs with East, West and South facing roof planes. Every system is unique.

East-West Facing Roof Solar Installation

Often we work with homes that do not have a south facing roof.  With the steep cost decline of solar modules and improved efficiencies, East and West facing roof planes are a solid option. An East or West facing roof at a 4/12 pitch produces only 13% less than a south facing array.  This loss can be easily compensated with the addition of a module or two.
