The cost of solar energy has dropped over 80% during the last decade. State and federal incentives can put some of the purchase price right back in your pocket. This means regular working families now go solar every day. Moreover, StraightUp Solar offers financing options that make it even easier. StraightUp Solar made the entire process an easy turn-key operation: from getting the building permit, to working with Ameren, to the actual installation, the process was much simpler than I expected, and so far the electricity production has been at or above the "theoretical" capacity on a regular basis.

Every size and type of farm is switching to solar power, from crops to livestock, community to industrial-sized. In fact, StraightUp Solar recently completed the largest agricultural solar installation in Illinois. Today Home Nursery, a major Midwest horticultural grower, boasts a solar system of nearly 2,000 panels, enough to generate 740,000 kWh per year or 100% of their total usage. Your solar generation goes directly to power your lights, equipment, etc. Solar does not change the way you use electricity-you just pay less to power your milking equipment, grain dryers, lights and fans, and other equipment.

We just completed a 50kw system on our office at Pyramid Electrical. The process from sales to design to commissioning could not have went smoother. Very professional staff.

Professional and very knowledgeable staff. I highly recommend!

Very comprehensive analysis of our system design. Brent's presentation was clearly understood.
