Elemental Energy is a highly experienced solar PV design and installation firm for residential and commercial clients throughout Oregon and Southern Washington. Locally owned and operated right here in Portland, we pride ourselves on providing creative solutions to your home or business energy needs, and aim to make the process of going solar simple and efficient.

"We had our house reroofed in January 2025. I got several bids, all came in about the same cost. We ended up selecting Elemental based on their knowledge of our existing system (Enphase) and their great description of what was going to happen. They coordinated with our roofing company to make the whole process seamless. The technicians that did the work were very professional and did a great job explaining what they were doing. The original mounting hardware had leaked a bit requiring our roofer to replace about 10 sheets of sheathing. The technician explained how the new mounting system would protect against leaks. They also applied some additional caulk to ensure a good seal. I would highly recommend Elemental for anyone that needs a removal/reinstall for reroofing."

Energy Efficiency Auditing questions, answered by experts

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.
