Services
Solar Thermal
Solar thermal systems use evacuated tubes to heat water for residential and commercial properties with 94% efficiency. This technology reduces energy costs by harnessing direct solar radiation, providing hot water, pool heating, and radiant floor heating. Ideal for Idaho's climate, it also melts snow on driveways and lowers utility bills year-round.
Solar PV
Solar photovoltaic (PV) installations convert sunlight into electricity for homes and businesses. These systems reduce or eliminate monthly power bills while qualifying for federal tax credits. Custom-designed setups ensure optimal energy production based on usage patterns and roof space availability.
Whole House Fans
Whole house fans draw cool air into homes while expelling hot air through attic vents. This energy-efficient solution lowers indoor temperatures by 5-10F, reducing reliance on air conditioning. It improves air circulation and cuts cooling costs by 50-90% during warmer months.
Electrical Upgrades
Electrical upgrades identify and implement cost-saving improvements for home energy systems. Services include LED lighting retrofits, appliance optimization, and integration with renewable energy sources. These upgrades enhance efficiency, reduce waste, and complement solar installations for maximum savings.
Radiant Floor Heating
Radiant floor heating systems use solar thermal energy to warm floors and living spaces efficiently. This method eliminates cold spots and reduces heating costs compared to traditional HVAC systems. It integrates seamlessly with solar thermal installations for sustainable, even-temperature comfort.

Carl did our solar heat system a few years ago and STILL comes to help when I forget how to do something. Never charges for the house call. I dont see service like that in any other industry. Buy with confidence.

We just built a home, we chose Renewable Energy NW LLC because we decided that, although a little more cost up front, we would definitely be paying less in the long run, all while staying extremely comfortable. They were super easy to work with and have been great to answer questions as I have had them come up over the past year. I LOVE showing my friends and family the system and bragging about how little our electrical bill is.

Carl knows solar. I hired him to install solar for our pool, our home hot water and our radiant heat. He saved me a lot of money through tax savings. His cost was reasonable and the energy savings are huge for my application. I will recoup my costs immediately due to tax benefits. PV solar would take years to recover costs. This system does what he says. Would highly recommend Carl
