Very thorough and informative whole house fan, chandelier and kitchen hood thru roof job. Josh explained in details and provided suggestions to protect my old circuits also.
Wanted to replace very old track lighting in living room with can lights. Submitted an estimate request on a Sunday night, Jason came out first thing Monday morning to check out the project and provided a timely and reasonable estimate later that day and followed up with a phone call. Work was completed today, one week later! Josh, Elijah, and Ricky were respectful of our home, took great care to keep things clean and were very pleasant. I don't know why we put this project off for so long! We finally have decent lighting in our living room! Will definitely use Dollens Electric for any future home projects/maintenance!

Great experiece with Dollens knowledgeable professionals !
They went above board to make sure every thing was done to perfection !
Professional, fair pricing, and stayed late to get complete the job. Excellent workmanship and could not recommend more.
These guys are great. Had power fail at one of our outbuildings; they offered to come fix it on Xmas eve but I said after Christmas was fine. They came out on time, got it fixed, all good. Highly recommended!
Excellent service & very competitive pricing. Would definitely use Dollens again & recommend them to others.
Excellent service with courteous and knowledgeable men
They have helped us a couple of times now. Will continue to use them going forward.
I apologize for leaving a 1 star review earlier. I wanted to leave a review for another electrician service with similar name.
Response from the owner: I apologize for your poor experience. But I believe you maybe confusing us with another company. We have not provided an estimate or service to Ben Yu.
The guys who came out listened to what I wanted to get done and got right on it. I’m very pleased with their work. More business to come!
Very pleasant and professional, but very expensive for 20 minutes of work.

Arrived on time and very capable with the installation and fixes
Response from the owner: Thank You Trajan Market. Working with you guys was great. We look forward to the next project.
Dollen's Electric are our one-stop shop for anything electrical! Great family business! Give them yours!
Response from the owner: Stacie, Thank You. We appreciate your support and great review. You're awesome.
We recently bought a vehicle and I contacted Jason and he came right away. The next day his son Josh, cousin Elijah, and their friend came by to install our 240 volt outlet with precision and quality. I would go to them again.
Response from the owner: Thank you. We are so glad you are happy with our work. We really appreciate the review.
Highly efficient service. Provided the best solution to charge our new Tesla avoiding purchase of a costly charger. Installed a 50amp line and outlet. Highly recommended.
Response from the owner: Thanks Joel! You guys enjoy that new car!
We had a great experience with Dollens Electric—they helped us replace old wiring, install new outlets, and install bathroom fans in our home (including adding the vents through the roof). They were very personable and easy to talk to, and it was easy to see that they put a lot of care into their work. We're looking forward to working with them again soon!
The work was completed as contracted. They were very professional nice.
They are simply the best. Polite, on time, communicative, and always ready to help with even mundane concerns. I’ll never use another electrician. Jason and his team are the gold standard.
Response from the owner: Thank you so much James. It is always a pleasure.
Dollens Electric has helped me on several occasions. I highly recommend them.
Response from the owner: It was good to see you again! You are very nice and easy to work for. I hope you get to see those grandkids soon!
Installed a whole house fan that is quiet and effective. Greatly reduces A/C cost. Workers are fast and efficient and cleaned up 100%. Quality products.
This is the second time we've used Dollens, first being when they upgraded the wiring to the entire house. This time they installed an isolated circuit in our garage and some can lighting. Even though it was a smaller job, they treated it just as importantly as the bigger job.They answered all our questions, let us know and talk through our options and didn't do any additional work without letting us know and approve the price difference for our requests, rather than telling us at the end of the job.A+ work!
Response from the owner: Thanks Mathew. You and your wife were great to work for. I still want to steal your dog!
We had a ceiling fixture out. Jason came on out and diagnosed the problem and got it repaired very promptly. Courteous and friendly.
Response from the owner: Thanks Lynne! It was a pleasure to met you!
Response from the owner: Deepak! Thanks for the review. I got to say you held your cool. It is mid December and we had to replace a major costly piece of your electrical system right before Christmas! Because you were so level headed you made it a pleasure to work for you. Thanks and Happy Hollidays!
Response from the owner: It was a pleasure working for you, Thanks for the review! Josh and Elijah mentioned how smart and energetic your son is almost every time they came back to the shop!
Professional, on time service. High quality work. Definitely will use again.
Response from the owner: Thank you Khanh, I am glad we have such great customers to work with.
Excellent. Whenever I again need electrical assistance Dollens is the one I'll call.
Response from the owner: Thank you Lynn.
Response from the owner: Thank you Denise. It is always a pleasure to work with you.
Update 9/2020 - Upgraded some thermostat wiring for me with a difficult routing. Professional and quick.Update - Jason and Josh again came through for me. In the midst of a heat wave, they were able to come to the other end of the county and fix an electrical problem at my mother's house. Got the outlets for the portable AC and lift chair back working and made the wiring safer to boot.Original - Could not ask for better. Jason installed a new 40 amp circuit and an EVo charger for our car. (No more slow 110 charging. Yeah!) While working in our breaker panel he noted a dangerous situation left by a previous contractor who upgraded our air conditioning.(Side note kind of disappointing the inspector didn't notice that the other contractor put in a bigger breaker on a wire that was too small. Luckily the wire insulation had just started to bubble and it didn't catch fire.)Within a week they were able to fit us in to replace the faulty circuit as well as rewire our garage lighting to eliminate some creative but scary runs of extension cords and re-purposed outlets. Now I have bright lights and when I look up, I don't see wires draped everywhere.We connected with Jason of Dollens Electric through our equally excellent general contractor Dan Mackey. (Who by the way had nothing to do with the faulty circuit or the creative garage lighting.)Lastly a thank you to Jason's son Josh who got to do the crawling under the house.
Response from the owner: We could not ask for better customers. We are looking forward to their next project!!!Thanks Maggie and Jim!!!
Response from the owner: Thank you Dana, we appreciate you and your feed back.
I've had a few projects done by Dollens..would highly recommend them...very trustworthy & professional
Response from the owner: Thanks Cyndie! Call us anytime, you're a great customer! I hope you and your Neighbor Dave's Work we completed last you two a long time! Good Job with the lights BTW.
Jason always does a great job, thanks
Response from the owner: Thank you Lindsay. It’s always great to see you.
I had Dollens come out to bid on installing a standby generator and they were friendly, on time, and professional. They walked me through options, explained what they were looking out and why and asked lots of follow up questions to make sure i was getting a bid for everything i wanted and needed.
These guys are the best. Very knowledgeable when troubleshooting old problems from less capable electricians who were here for prior owners. Installed a new outlet in my hardwood floor that looks beautiful along with solving our "where to put the lamp" problem. Lastly wired up a cat6 network allowing us to move our router/hub into a closet off my desk.Call/use them; you won't be sorry.
On time, explains the work so you will understand what was done and why.
Jason, Josh, and Elijah were prompt, considerate, professional, trustworthy, and kind. The work for our recessed lighting project was done quickly and with care, precision, and high quality. Jason was very thorough in explaining what they had done and why. I would have no reservations with them and highly recommend them!
This company is great. They were always on time and great at communicating both time estimates and costs. They are very thorough, knew current codes inside...

Solar Energy

Solar panels are an excellent way to generate renewable solar energy and reduce your carbon footprint. They require little maintenance and can last up to 25 years.
With technological advances, solar panels are becoming more efficient and affordable. Switching to solar benefits the environment and can provide long-term financial benefits. Make the most of the sun by powering your home or business with clean, renewable energy.
The solar panels cannot generate as much energy when the sun goes down or on cloudy days. This is where solar battery storage comes in, providing stored energy to Power your home or business. This process is known as “load shifting” and is a key benefit of solar batteries.

Home Battery Energy Storage

Energy independence means homeowners can lower their electricity bills and reduce their carbon footprint. Home batteries are now cheaper and better, so homeowners can save money and energy by investing in them.

What Are Home Batteries?

Home batteries, also known as energy storage systems (ESS), are becoming increasingly popular among homeowners. The following are four popular ways they can be integrated into your home. 

Everything You Need To Know About Solar Batteries

Home battery backup systems are no longer a luxury. You don’t have to break the bank or wait forever for a solar-powered storage solution. They can work with the grid to lower your electric bill, work with solar and the grid, or work independently from the grid with a solar system. 

Several types of solar batteries are available on the market, each with unique features and benefits. The most common types are lead-acid, lithium-ion, and saltwater batteries.

  • Lead-acid batteries are the most commonly used solar batteries. They are known for their reliability and affordability. They are also the oldest type of rechargeable battery, having been used in various applications for over 150 years.
  • Lithium-ion batteries are becoming increasingly popular due to their high energy density and longer lifespan than lead-acid batteries. They are also more lightweight and compact, making them a popular choice for residential solar energy systems.
  • Saltwater Batteries: This type of battery is relatively new to the market and is gaining popularity due to its eco-friendliness and safety. Saltwater batteries use saltwater electrolytes instead of toxic chemicals, making them a more sustainable option.

This allows customers to:

  • Charge the batteries at night when Power is less expensive and use them during the day. This will lower or eliminate the home’s power consumption during the most expensive time of day.
  • Have Power during an outage.

This allows customers to:

  • Solar panels charge during the day and can be used at night or in low sunlight. This will enable homeowners to reduce their reliance on the grid and save money on their energy bills. 
  • This allows the solar system to eliminate grid consumption during the day when the sun is out and top off your battery. Your home will be tied to the grid but will not be pulling power from the grid during this time. 
  • Have Power during an outage.

Stand By Generator

We assist with installing and maintaining your generator. Our maintenance services keep your generator ready for use, utilizing high-quality equipment to ensure smooth and efficient operation.

Lighting Installation

  • Solar panels charge them during the day for use at night or in low sunlight. This allows homeowners to reduce their reliance on the grid and save money on their energy bills. 
  • This allows the solar system to eliminate grid consumption during the day when the sun is out and top off your battery. Your home will be tied to the grid but will not be pulling Power from the grid during this time. 
  • Have Power during an outage.
  • You can use the generator to charge the battery without solar grid power. This is great when you are experiencing an outage for extended periods and don’t want to hear the generator constantly running.

How to Choose the Right Solar Battery

When choosing the correct solar battery for your needs, there are a few key factors to consider.

Depth of Discharge (DoD)
  • The depth of discharge (DoD) refers to the energy that can be used from a battery before recharging. For example, a battery with a DoD of 80% can be discharged up to 80% before recharging.
  • It’s important to consider the DoD when choosing a solar battery, as a higher DoD means you can use more of the stored energy before recharging. However, a higher DoD can also decrease the battery’s lifespan. Hence, finding a balance that works for your needs is essential.
Round-Trip Efficiency
  • Round-trip efficiency refers to the amount of energy stored in a battery compared to the amount used to charge it. For example, a battery with a round-trip efficiency of 80% means that 80% of the energy used to charge the battery can be stored and used later.
  • A higher round-trip battery uses energy more efficiently during charging and discharging, reducing waste. When choosing a solar battery, it’s important to consider the round-trip efficiency to ensure you are getting the most out of your energy storage.
Warranty

Solar batteries can be a significant investment, so it’s important to consider the warranty when purchasing. Most solar batteries guarantee 5-10 years, but some may offer longer warranties. It’s important to read the warranty carefully and understand what is covered and for how long.

How to Maintain Your Solar Battery

Proper maintenance is essential for ensuring the longevity and efficiency of your solar battery. Here are a few tips for maintaining your solar battery:

  • Keep it Clean: Regularly clean the solar panels and battery to remove any dirt or debris affecting their performance.
  • Check the Connections: Make sure all connections are secure and corrosion-free.
  • Monitor the Temperature: Extreme temperatures can affect the performance and lifespan of your solar battery. If possible, keep the battery in a cool, dry place.
  • Avoid Overcharging and Over-Discharging: Overcharging and over-discharging can damage your solar battery. Make sure to follow the manufacturer’s recommendations for charging and discharging.
