Energy Resources

AERO is excited about the growing interest in alternative energy generation around the state of Montana, and we hope you are too! Several helpful links and calculators are provided here to help you determine what type of project is best for your situation, and what you can expect from a renewable energy system.

Renewable Energy Links

Alternative Energy Project Toolbox

  • Solar-Estimator is a great tool to learn about the financial and energy benefits of renewable energy for your home or business. You can examine the results for solar hot air, solar hot water, photovoltaics, or wind systems in regards to your location and utility consumption and expenses.

Photovoltaic

  • PVWatts calculates the expected PV production of your exact location to determine your system requirements.
  • Findsolar uses your location and monthly utility usage to determine the correct PV system size for you.  Their analysis also includes personalized information on insolation, cost, incentives, lifetime savings, and environmental savings.
  • Bozeman Green Build Calculator provides an in-depth analysis of the production and financial incentives of a photovoltaic system. This spreadsheet requires the user to input system size, system cost and whether they qualify for the NWE Grant. These inputs can be determined with the Solar-Estimator and through Northwestern Energy E+ Programs.

Solar Hot Air

  • Energy4You gives a brief explanation of solar hot air and specifications for a few highlighted systems.

Solar Hot Water

  • Free Hot Water provides a simple solar hot water calculator to determine your system specifications and expected savings.
  • Infinite Power calculates savings and production from solar hot water, relying on current water heater specifications.

Wind

  • Energy Efficient Choices will determine the financial and energy incentives of a wind turbine system sized to meet your energy consumption and location.

Biomass

  • Green Heat Initiative provides a user-friendly calculator to estimate how a biomass heating system may be beneficial for your home.

Energy Conservation

  • Home Energy Saver provides potential house upgrades to save you money. This calculator requires detailed information about your home to quantify potential savings and identify necessary upgrades for home energy efficiency.
  • Energetech compares energy efficiency of windows by brand and type through an easy-to-use spreadsheet.

Energy Monitoring Systems

  • TED provides high-quality monitoring systems for real-time feedback of energy production and consumption for your facilities.
  • PlotWatt is an online monitoring dashboard that displays real-time data for both your generated energy and your facility energy consumption. This is a great tool for businesses and homes even if you don’t have a generating energy system. PlotWatt recognizes different appliances and provides an in-depth analysis of your consumption along with ways to reduce your consumption.
