One of the limitations of some grid-tied photovoltaic systems is that the owner will only benefit as long as there is sunlight while the grid is functioning. Otherwise, if there is an outage, they may not even use the energy they are generating from the rooftop. During such times when the grid is disconnected, the owner can neither use the rooftop solar nor export the energy to the grid.

Owners of PV systems without backup functionalities can upgrade by adding AC coupling. This enables them to store energy and use it anytime, including during emergencies and grid outages. The AC coupling converts a simple grid-tied system into a Grid/hybrid or grid interactive system. This provides grid-ties savings whenever the grid is up and running, and off-grid independence, as well as security when there is a utility outage.

The main components of AC coupling include an energy storage system, a grid-interactive inverter/charger, a coupling device and the second panel with additional wiring for the critical loads to supply during outages.

Battery storage enables better power management by providing a number of benefits which include:

We’ve discussed this at length in the past, so we’ll stick to the cliff notes here. Disreputable electricians in Baltimore are any that lack current, in-state licensing. Those that carry no official, genuine documents, and those that operate from unmarked vehicles. These types of companies also often ask for cash up front, and are just as likely to disappear as to do the project they were hired for.

When you’re looking to hire electricians in Baltimore, keep in mind that you’re putting a huge amount of your personal assets and heath on the line. By dealing with a company that isn’t recognized, you risk:

If you're looking to increase the efficiency of your home, there's some good news: Not only can you save a bundle of money with lower utility bills, studies show that you will be able to sell your house faster, and for more money as well. Green houses are attracting more attention on the market, so when it does come time to sell you could see a big increase in the price.

Decision Influencers 

Efficiency matters. Ninety percent of potential homebuyers rate home efficiency features as “very important,” according to a survey by the National Association of Homebuilders. The survey went on to report that 61 percent of buyers would pay up to $5,000 more for a house that promised lower utility bills. Other studies found that green-certified houses sell for $34,800 more than similar homes without efficiency features in California, and green houses in Seattle, Wash., and Portland, Ore., sell at a premium of 8.5 percent and 12 percent, respectively. The Seattle study also found that the green homes sold 22 percent faster than others.

Make sure your realtor is aware of all the efficiency upgrades you’ve made and can highlight them to interested buyers. If you provide old utility bills you can really showcase the savings. 

Keep that Electric Bill Low

The electric bill is one of the biggest ongoing household expenses, so any reductions you make will go a long way. There are a lot of places to look for savings. For starters, if you have old, outdated appliances, replace them with new Energy Star-certified models so you know that they meet the strictest efficiency standards. Your lighting system is another place to upgrade -- it's time to toss old incandescent bulbs and replace them with compact fluorescents or LEDS. Finally, if you really want to save money and make your house look good to buyers, install some solar panels on the roof, which can reduce the electricity bill to near zero. 

How Else Can I Increase My Efficiency?

Don't forget to take other steps to increase the energy efficiency of your home, especially when it comes to heating bills:

You can also hire a qualified professional to conduct an energy audit and point out other ways to increase your efficiency and save money. Even if you don't plan on selling your house any time soon, you can enjoy seeing the savings in your bills each month.

Spring is the time of year that everybody loves to spend outside. We are finally free of the freezing temperatures brought on by winter, but still have a few months before the oppressive heat of the summer rolls into town. Because people are often cooped up all winter, the desire to be outside is very strong. Spring is the perfect time to catch up on any yard work or remodeling that you have been planning, to ensure that your home is ready for hours of outdoor entertaining. But you should always be aware of the threat your electrical system could pose if you are not absolutely careful.

Here are a few tips for staying safe around your electrical systems this spring:

The future looks bright here at Mr. Electric®, and we hope the same for you! As you are mentally preparing for the New Year ahead, maybe you are planning your goals and resolutions for personal development and improvement. This video by our president, Joel Worthington, is sure to motivate you to achieve them. We also want to encourage you to consider your home’s development and improvement, too!

When you think about your home’s electrical system, what can be improved? What can be replaced and updated? We have put together five tips to help you get started on getting your home’s electrical system in tip-top shape for the New Year. 

Although they initially cost higher, LED Energy Star qualified bulbs end up paying for themselves in energy savings in about 10 years. They use 75 percent less energy than incandescent bulbs and last 35 to 50 times longer. Plus, they offer more peace of mind since they emit very little heat, decreasing the threat of an electrical fire, and are much more durable, so they won’t shatter all over the floor. They’re also guaranteed for three years minimum, which is above and beyond the industry standard, so you’ll save on maintenance costs as well as energy costs. Basically, there’s no excuse not to get them!

Did you know that you’re technically supposed to do this every month? Not many consumers actually do this, but a new year is a great time to put this to practice and schedule it along with your other monthly home maintenance routines. You’ll find these outlets in moisture-prone areas such as the kitchen and bathroom as the current National Electrical Code requires. Simply press the test/reset button and make sure the outlets trip and resent correctly. If they are malfunctioning, call your local Mr. Electric to have them replaced to reduce electrocution risk.

Replacing the batteries should be done at least once a year, and both of the detectors should be tested monthly to ensure proper functionality. And speaking of replacing, how old are your detectors? Remember that smoke detectors need to be replaced every 10 years. Depending upon the model, older model carbon monoxide detectors should be replaced every three years, and the newer ones, every 5-6 years. Make safety a priority for your home and get this done!

Power surges can enter your home unexpectedly during a stormy night, a random power company disruption or operation of a heavy-duty electrical appliance. They destroy electronic devices in their path and at times cause fires as well. It is unfortunate when your Mac or PC dies, but even more so when your photos, documents, music and other personal content are lost along with it as well. To reduce damage from power surges, have a whole house surge protector installed by your local Mr. Electric at the panel and additionally multi-outlet power strip surge protection for delicate circuitry, telephone and cable lines. This will ensure both main zone as well as secondary zone surge protection to absorb any excess power that seeps through the primary protection.

This can be done in a variety of ways: turning lights out after you leave a room, unplugging and turning off electrical devices when not in use and ensuring lighting and appliances are Energy Star qualified. Perhaps you can create a friendly family competition to see who can use the least amount of electricity, or even consider looking into installing a solar energy system for your home. Whatever you choose to do, remember that you can also call your local Mr. Electric to perform an energy audit for your home to ensure its electrical system is operating at maximum efficiency.

We hope you find these tips helpful to make your home’s electrical system the best and brightest it can be, and we wish you a Happy New Year from all of us at Mr. Electric!
