Our ground mounts utilize galvanized steel posts which are set in concrete a minimum of four feet in the earth. Solar modules are long term, no maintenance by design so we want our mounting structure to be as well.
We are seeing some companies utilizing precast cement block to hold their solar structures. This is a way around having a backhoe for installation and its cost. However, any foundation built correctly, needs to be placed below the frost zone so it stays in one place.
Looking at a number of these precast units after one winter shows movement of one portion of the solar array one way and the next another direction. Frost heaving through the year has moved the entire precast block. What will this look like after 10 years. Not very good in our view.
We do not believe this is a place to skimp and have our own excavating equipment to keep the cost down as low as possible.

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 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.
Selway the SBS Solar Dog was very happy when Montana Gov. Steve Bullock vetoed Senate Bill (SB) 7 last week.
Frank Andorka writes in PV Magazine,Sanity prevailed in the Montana’s governor’s mansion last week as Gov. Steve Bullock vetoed a bill that would have effectively ended net-metering in the state. (Read all the details)
