https://personalpowerproject.com/ Personal Power Project - Solar Panel Installation Business. We install solar panels, and our specialty is helping people to reduce all of their energy bills to ZERO per year, when the average in CA is approaching $10,000 per year. For most people their electric bill is only one third of their total energy expense. Natural gas or propane gas for your home and gas for your cars amount to the other two thirds. This takes long range planning and that is what we do. If you need an emergency repair or service ASAP, we do that too although it's not our main focus so probably faster to get another company for emergency jobs. Our business model is to help you go 100% off grid while still being connected, if and when you need it. It's easy to be 100% off grid if you are not 100% electric. Being 100% off grid and 100% electric, on everything else is difficult and takes a lot of research, resources, planning, and some good advice and direction. Governments worldwide are mandating the all-electric movement so there is no avoiding it. It might take years for you to get there, which is not unusual and it's worth it, to eliminate $10,000 worth of energy bills per year which continue to climb higher each year. We dispatch our local solar contractors from our nationwide solar companies, of your choice, for all the help you need.

An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency.
A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
