Average Savings
Great Falls’ energy landscape presents exceptional opportunities for solar adoption. With NorthWestern Energy electricity rates rising consistently and Central Montana’s harsh winters and Chinook wind events requiring reliable backup power, homeowners and businesses across Cascade County are discovering the financial and practical benefits of solar energy and battery storage systems.
Montana electricity rates have increased steadily over the past decade, with NorthWestern Energy residential rates now averaging 10-12 cents per kWh. Solar systems lock in your energy costs for 25+ years, providing predictable savings that compound as utility rates continue climbing. Great Falls businesses face commercial rates averaging 9-11 cents per kWh plus significant demand charges.
Central Montana experiences dramatic weather swings—extreme winter cold, heavy snowstorms, powerful Chinook winds, and severe summer thunderstorms that regularly disrupt power across Cascade County. Battery storage systems provide essential backup for home comfort, heating systems, medical equipment, and business continuity. Average Great Falls home experiences 3-5 power outages annually—battery systems bridge these gaps seamlessly.
Great Falls receives 5.2 peak sun hours daily and approximately 205+ sunny days annually—outstanding solar resources for Montana and well above the national average. The high-altitude environment and low humidity maximize panel efficiency year-round. Well-designed systems generate 1,200-1,450 kWh annually per installed kW, providing excellent return on investment for Central Montana installations.
The 30% Federal Investment Tax Credit remains available through 2032 for all solar installations. Montana offers property tax exemptions for residential renewable energy systems, ensuring your solar investment doesn’t increase property taxes. Net metering with NorthWestern Energy ensures you receive retail credit for excess solar production. Commercial installations qualify for accelerated MACRS depreciation, recovering 85% of costs within six years.
Whether you’re a homeowner looking to reduce utility bills, a contractor serving the Greater Great Falls area, or a business seeking to cut operational costs, PES delivers the products, expertise, and logistics support to ensure project success in Central Montana’s climate and competitive energy market.
Take control of your energy bills with solar systems engineered for Montana’s extreme winters, Chinook wind conditions, and NorthWestern Energy net metering programs. Our pre-designed kits include high-efficiency panels, inverters, racking systems, and all necessary components—paired with PowerLink-certified local installers who understand Montana building codes, heavy snow loads, and utility requirements for NorthWestern Energy service territory.
Average Great Falls installation: 5-8 kW system producing 7,000-10,000 kWh annually—enough to offset 70-90% of typical household consumption while withstanding Montana’s harsh conditions.

“Switching to solar with PES in Great Falls saved us over $1,100 in our first year alone. Our 7.5kW system now covers most of our electricity usage, and the Tesla Powerwall kept our heat and essentials running during last winter’s severe cold snap when power was out for 12 hours. The PowerLink installer they recommended handled all the permits and NorthWestern Energy coordination seamlessly. Best investment we’ve made for our Great Falls home.”
“As a solar contractor serving the Greater Great Falls area, PES’s fast delivery has been a game-changer for my business. When I need panels or inverters for installations across Cascade County, materials arrive within 48 hours without me maintaining massive inventory. Their PowerLink bulk pricing and responsive support team have given me a real competitive advantage in Montana’s growing solar market. Plus, they understand the heavy snow load requirements we deal with here.”
“Our agricultural operation near Great Falls was paying $3,800 monthly to NorthWestern Energy. PES designed a 75kW rooftop system that’s cut our electricity costs by $2,000 monthly—over 52% reduction. The federal tax credit and accelerated depreciation made the financial case compelling. System paid for itself in 5.8 years and we’ve essentially eliminated demand charges during peak operations. Highly recommend for any Great Falls-area business.”
Documented outcomes from residential, commercial, and utility installations throughout Cascade County and the Greater Great Falls area.
A 2,400 sq ft home in Great Falls installed a 8kW Aptos Solar system paired with a 13.5kWh Tesla Powerwall 3 battery. The system was designed to offset 80% of annual consumption while providing 16-20 hour backup power for essential circuits including heating system, refrigerator, sump pump, and internet during Montana’s frequent winter storms—critical for Chinook wind conditions and cold weather outages.
System payback period: 7.8 years after 30% federal tax credit. Maintained power during 6 outages in Year 1 totaling 28 hours—performance exceeded projections by 6% due to high-altitude solar intensity.
A 12,000 sq ft professional office building in downtown Great Falls installed a 100kW rooftop solar array to offset high NorthWestern Energy commercial rates plus significant demand charges. System was designed to cover daytime electricity consumption when building operations and HVAC loads are most intensive—particularly during Montana’s cold winters requiring maximum heating capacity.
Projected 25-year savings: $980,000+ including avoided utility rate increases. 5.5-year payback after federal Investment Tax Credit and accelerated MACRS depreciation—system performance 4% above first-year estimate.
