St Pauls Lutheran Church in Missoula goes Solar

The SBS Solar team recently installed a 26.9 kW solar electric system for St Pauls Lutheran Church in Missoula MT.

A portion of the funds for this project were provided by USB (Universal Service Benefits) funding in Montana. In 1997 the Montana legislature passed an electric deregulation law that included language establishing a Universal Systems Benefits (USB) fund.

What are the Electricity USB Programs?

  • Low Income (energy assistance and weatherization)
  • Cost-Effective Conservation + R & D
  • Market Transformation
  • Renewables + R & D

Under this program (with these guidelines the E+ Renewable Energy Program (NorthWestern Energy) provides custom incentives for projects that benefit organizations and communities for non-profit or government facilities.  Projects receiving these funds often provide civic value including education and visible representation of renewable energy technologies to a broad audience. Broad Benefit Commercial solar PV incentives are awarded twice a year, once in the spring and once in the fall.

If your non-profit is interested in assistance with the grant application call us today. 406-541-8410.

The next round of proposals is due by March 31 2019. Proposal information is included in the Anywhere Library Exampleand the application requirements.  

The 5 criteria used  to rank proposals are as follows:

  1. Non Profit
  2. Geographic Location
  3. Participant Match ( at least 10%)
  4. Educational Value
  5. System Maintenance

 

Designing Solar Electric Systems with Growth in Mind

Solar Electric Systems Missoula Montana

There are many considerations to take into account when you are designing a solar electric system.  And growth is one of the considerations.  Perhaps you design a system to suit your current electric usage, but then want to add an electric car into the mix.  So the question is can you add to a solar electric system.  The answer is a qualified yes.

Discuss your current and potential needs with your design consultant.  Design the system with a large enough inverter to handle future additional modules.  Perhaps you hope to add batteries in the future.  All of this is significantly easier if your start with the end system in mind. Give us a call 406-381-5643.

Ground Mounting System with a Firm Foundation

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.

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

Solar Installation Missoula

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.
