Solar Myth # 7 I will have an excess of energy that will go unused and will be wasted
Fact: Nearly all modern solar panel systems are connected to the conventional electric utility grid. When this happens, your meter spins backwards and your utility company credits you for that power. This grid-tied method tends to be the most convenient for homeowners. This is ideal for us in Montana, because of our long solar days in the summer and shorter days in the winter time. In Montana the utility company will not write you a check for excess energy that you produce. So generally your system will be sized to accommodate your average annual usage. (determined by your utility bill). Each year the solar electric system generates power during peak season (summer), and you consume power during the darker, shorter days of winter. The utility company (each one slightly different dates) resets once a year and the process begins again.
One often stated myth is that manufacturing solar panels requires more energy than the solar module will produce is simply not true.
According to a 2004 National Renewable Energy Laboratory study that analyzes several different panel technologies, “Producing electricity with photovoltaics (PV) emits no pollution, produces no greenhouse gases, and uses no finite fossil fuel resources.” and it takes only 1 – 4 years for the energy savings accumulated by producing electricity from solar to equal the energy cost of producing the panel.
Solar technology has improved in the years since this study was conducted, and production efficiencies have driven the “energy payback period” down even further. Solar modules generally have a 25 year warranty and can continue to produce long after that time frame(at a slightly reduced rate) lifetime production of a solar module exceeds far embedded costs.
Valley Villas is one of the largest solar electric systems in Montana. It has many unique features, three separate buildings, 34 apartment units, with two laundry rooms. SBS Solar used all SolarWorld 325 modules and Fronius inverters.
The developer and architect on the project kept their eye on efficiency.

And of course individually Net Metered photovoltaic systems to help with energy costs
This landmark installation offers efficient affordable housing units that are a model for the affordable housing industry.
Solar electric modules will produce energy even on cloudy days. Although it might seem counter-intuitive, consider that solar panels on a rooftop in foggy San Francisco produce nearly the same as the ones in nearby sunny Sacramento. Consider too that Germany (with a climate not that different from Vancouver Canada) leads the world in residential solar right now, and it is generally an overcast climate.
While the amount of sunlight your panels receive is important, a more accurate representation of the amount of energy your panels can produce is referred to as peak sun-hours or equivalent full sun. It is important, first of all, to note that “peak sun-hours” are not the same as “hours of daylight.” Peak sun-hours refers specifically to how much solar energy is available in an area during a typical day. As a comparison Phoenix Arizona has equivalent full sun value of 6.5, in Western Montana we use the equivalent full sun value of 4.5. The same equivalent sun hour value as a good part of the continental United States.
Have you ever heard that solar doesn’t work in Montana? Simply not true. Montana is a great state for solar. Dan Brandborg has been selling, installing and living with solar electricity in Montana for 30 plus years.
That being said, the true game changer in Montana was net-metering. This allows Montanans to harness the sunshine generated on our long solar days in the summer time, feed back into the utility grid and use the power during our shorter winter days. Solar irradiation levels vary across the United States, but every state receives enough sunlight to make solar a good investment. Solar panels will continue to produce a significant amount of energy even on overcast days. Germany has more solar than any other country in the world (and six times the installed capacity of the U.S.), yet Germany’s solar resource is roughly equivalent to that of Alaska. Solar can work in almost any climate, as long as panels are properly installed in an un-shaded location. Solar panels work with light, not heat so it doesn’t matter how cold it gets outside. In fact, solar panels perform better in cooler temperatures than very hot temperatures.
The Missoula Federal Credit Union is a
not-for-profit, member-owned financial institution, serving people who live, work, worship, or belong to
an association headquartered in Missoula, Lake, and Ravalli counties. (Not a member? No Problem. Becoming a member is easy, and is well integrated into the loan application process and can be done via mail, and need not include any financial services beyond the loan. Membership in the Montana Renewable Energy Association would qualify a
borrower for MFCU loans, making them available to the entire state. Check out the Missoula Federal Credit Union Home Energy Loan Brochure. Or Call (406) 523-3300.
Federal Tax Credits Residential 30% Renewable Energy Credit (thru 2019)This tax credit is applicable for all primary and secondary private homes. It includes all associated costs, such as installation and electrical work.
State (Montana) Tax Credits Montana State provides a 500.00 per tax payer tax credit, or 1000.00 per couple for your solar installation.
This program helps increase American energy independence by increasing the private sector supply of renewable energy and decreasing the demand for energy through energy efficiency improvements. Over time, these investments can also help lower the cost of energy costs for small businesses and agricultural producers.
Grants of $20,000 or less: October 31, 2017 and March 31, 2018;
Unrestricted Grants (up to $500,000): March 31, 2017;
Loan Guarantees are competed continuously throughout the year.
Don’t miss this unique opportunity to invest in the long term health of your business with an investment in solar energy and energy savings.
