If you own a
commercial building, you can get a solar power system essentially free. Here’s how we did it.
First you
have to decide how large of a system to buy (how many panels). To optimize the financial yield of our
system, we purchased an array that maximized the southern roof exposure of our
building. This array will produce about
70% of the electricity we use annually (our building is located in Appleton,
Wisconsin). This is about ideal, because
as you attempt to reach 100% solar, the marginal return on the incremental
investment in panels will diminish. In
the months we over produce (make more energy than we use), WE Energies pays us
a wholesale price for the overproduction.
The wholesale price is $.04/kwh, compared to the $.13/kwh we effectively
get by offsetting the energy we use in a month.
Keeping our investment to a 70% system minimizes the number of months we
overproduce, and thereby maximizes the rate of return on our investment.
Our system
will save us about $550 per month on average, and our loan payment (10 year
amortization) is only $420 per month. So
there you have it: zero down and positive cash flow every year. That’s better than free. When the system is paid off, it should save
around $7,000 per year, and the system has an expected useful life of 25 years.
Act
fast! - the 30% federal tax credit
available in 2019 drops to 26% in 2020, 22% in 2021, and 10% in 2022. Thank you Appleton Solar (www.appleton-solar.com) and WE
Energies for making this possible.
