NRG Clean Power is California’s leading clean power provider. We leverage over 30 years of superior customer service installing solar from the south of San Diego to the northern border with Oregon. In other words, regardless of where you are in California, we can help you make the switch to solar! Not only do we offer top-tier solar services, we are also a total home performance company, devoted to sustainability and energy efficiency. We offer fully customized home and business solar installations with battery backup capabilities. We do not service solar systems that we did not install. We believe the future is clean, renewable energy and with your help we are committed to creating it together. Customer satisfaction is a crucial aspect and the cornerstone of our business. As a result, we have earned the prestigious Diamond Certification 4 years in a row, along with the 2019 Angie’s List Super Service Award. NRG Clean Power offers the finest solar products at the best rates with finance options for everyone. We will be with you every step of the way and for years to come. Check out our promos to take advantage of our best deals. And ask about our Referral Program that allows customers like you to earn cash bonuses for referring friends and family!

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

We are a family-owned company that has been in the spray foam business for over 20 years serving Fresno, Clovis, Bakersfield, Oildale and surrounding areas of Visalia California for many years. Spray polyurethane foam (SPF) is a spray-applied plastic that is widely used to insulate buildings and seal cracks and gaps, making a building or home more energy-efficient and comfortable. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints.Attic Spray Foam Insulation Did you know you could be losing up to 40% of your homes energy through the attic alone?! Using Spray Foam Insulation in your Attic is the only solution you should be considering to remedy your attic’s insulation needs. The attic is the part of the house which is easily over looked, but it is also the part of the home that is most susceptible to the external temperature changes. If you attic is not properly insulated it can lead to huge amounts of energy loss and the fluctuation of the temperature within your home. Proper attic spray foam insulation serves as the key to limit and control the effect of the external temperatures on your homes interior environment, monthly energy bills and energy loss.

Energy Efficiency Auditing questions, answered by experts

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.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.
