Trustworthy very much describes Dollens Electric. Jason and his team including Josh and Elijah are reliable, honest, and efficient. I have used Dollens for major and small jobs and they stand by their work and rightfully so. Don't be fooled by cheap quotes that lure you in with the thought of getting major work done for a cheap cheap price. You get what you pay for and with Dollens, you get a great job for a fair price. Dollens is my go-to electrician.

I was installing a new cooktop and got a bit confused about the wiring in our situation. Scheduled an appointment for Monday but they were able to come at the end of a Friday and spent an hour cleaning up the wiring and getting my old wiring up to code. Very friendly guys, did good work and explained what they were doing as they were doing it. Will call them again when I need electrical work

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!

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!

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.

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.

Everything You Need To Know About Solar Batteries
Get Solar Energy Storage Solutions
Home battery backup systems are no longer a luxury. You don’t have to break the bank, or wait around forever for solar-powered storage solution. They can work with the grid to lower your electric bill, work with solar and the grid, or work independantly from the grid with a solar system.
Several types of solar batteries are available on the market, each with its own unique features and benefits. The most common types of solar batteries are lead-acid, lithium-ion, and saltwater batteries.
- Lead-Acid Batteries: These are the most commonly used solar batteries and are known for their reliability and affordability. They are also the oldest type of rechargeable battery and have been used in various applications for over 150 years.
- Lithium-Ion Batteries: These batteries are becoming increasingly popular due to their high energy density and longer lifespan compared to 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.
What Are Home Batteries?
How Do Solar Backup Batteries Work?
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 you home.
Batteries with Grid
This allows customers to:
- Charge the batteries at night when power is less expensive and use the battery during the day. This will lower or eliminate the homes power consumption during the most expensive time of day
- Have Power during an outage
Batteries with Grid and Solar
This allows customers to:
- Use Solar panels to charge them during the day for use at night or in low sunlight. This allows homeowners to reduce their reliance on the grid and to save money on their energy bills.
- Allows the solar system to eliminate the grid consumption during the day when the sun is out and top off your battery. Your home will be tied to the grid but not pulling power from the grid during this time.
- have power during an outage
Batteries with Solar, Generator, and Grid
- Use Solar panels to charge them during the day for use at night or in low sunlight. This allows homeowners to reduce their reliance on the grid and to save money on their energy bills.
- Allows the solar system to eliminate the grid consumption during the day when the sun is out and top off your battery. Your home will be tied to the grid but not pulling power from the grid during this time.
- Have power during an outage
- Use the generator to charge the battery when there is no solar our grid power. This is great for when your in an outage for extended periods and don’t want to hear the generator constantly running
This energy independence means that 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.
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 advances in technology, solar panels are becoming more efficient and affordable than ever before. Switching to solar not only benefits the environment but can provide long-term financial benefits. Make the most of the sun by powering your home or business with clean, renewable energy.
When the sun goes down or on cloudy days, the solar panels are not able to generate as much energy. This is where the 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.
How to Choose the Right Solar Battery
When it comes to choosing the right 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 amount of energy that can be used from a battery before it needs to be recharged. For example, a battery with a DoD of 80% means that it can be discharged up to 80% before it needs to be recharged.
- 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 needing to recharge. However, a higher DoD can also decrease the lifespan of the battery, so it’s important to find a balance that works for your needs.
Round-Trip Efficiency
- Round-trip efficiency refers to the amount of energy that can be stored in a battery compared to the amount of energy 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 making a purchase. Most solar batteries come with a warranty of 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 that may affect their performance.
- Check the Connections: Make sure all connections are secure and free of corrosion.
- 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.
