Affordable Solar Energy in Eugene, OR
Serving Lane County since 1994
- * Free quotes for qualified sites. Qualification includes site shading and orientation; remaining life of roof; travel time to the site; and attic construction and condition. Unfortunately, we cannot offer free quotes to Springfield Utility Board customers at this time. Qualification for a free quote is at our discretion. If your site does not qualify, we may be able to offer you a free phone consultation and you may have the option to pay for a site assessment. Site assessments typically run from $100-200, depending upon distance and/or complexity.
Solar Electric Systems
Solar electric ("photo-voltaic" or "PV") systems are becoming an increasingly cost-competative form of energy for Oregon homes and businesses with sufficient solar exposure. We offer a free Solar Site Assessment to help you decide if it's a good fit for you. PV installations on south facing roofs with minimal shading can provide an annual financial return of up to 11% with a payback of as little as 9 years. East and west facing installations can also be financially attractive when shading is minimal.
We offer both grid-tie and grid back-up solutions. Grid-tie solutions recieve a credit back from the utility when your system produces more power than your home or business is using.
Heat Pump Hot Water Systems
Heap pump water heaters gather solar energy 'indirectly' by extracting stored solar heat from the air. These systems are gaining in popularity due to their relatively easy installation, lower cost, and no requirement for rooftop solar resources.
Heat pump water heaters can supply approximately 50%-70% of the annual hot water load, and have good effeciency throughout the year. In homes with a smaller load, only 1 or 2 people, the hot water savings of heat pump systems are much greater than that of a solar hot water system, making these systems the more cost-effective choice.
Solar Hot Water Systems
Solar Hot Water systems can be used for a variety of purposes. The most predominant system is the solar domestic water heater. Since every home and many businesses use hot water year-round, this is a consistent load that can be significantly offset by simply preheating the cold city water that feeds the electric or gas water heater with solar heated water. The intensity of the sun varies with the seasons and so does the temperature of the solar water produced.
Summertime months typically result in nearly 100% solar heated water for a well sized system. The winter months average around 25-50%. This results in an annual average of about 60-70% of your hot water load being provided by the sun.
