Choosing the right size depends on the level of energy independence that a renewable energy owner wants. It may simply boil down to what you can afford. These levels range from 100 percent or completely off the grid (the most costly), to a simple energy backup for emergencies.

100% energy independence or completely off the grid: this requires a huge investment in terms of generation and storage. In addition, it may require other power sources such as fossil fuels or wind generators.

High energy independence: This requires a solar system with enough batteries to last a few days or even through the winter. PV systems are sized to enable the owner to have surplus energy to store during summer and be self-sufficient through winter without relying too much on the grid. The customer will still rely on the grid for backup just in case there are prolonged days of bad weather.

Summertime independence: Customer installs just enough panels and storage capacity to get through a normal summer day but will have to draw power from the grid during the winter.

Peak time independence: Battery size should be large enough to supply power during peak times when electricity rates are highest.

Reduced reliance on the grid during peak times: Some customers cannot afford to install enough storage to cover their entire peak time usage. In such a case, some will install a system that will enable them to at least reduce part of their grid usage during these times.

Emergency power backup: This requires smaller energy storage, enough to cover a short power outage. Some customers use this together with fuel generators. Battery storage is only required for the short duration from the time grid power goes out, to when the alternative power becomes available.

Even though a solar energy system is a great investment that reduces your electricity bills, it is not possible to completely get off the grid without investing in large storage systems. However, adding modest battery storage to a grid connected to solar systems is a better way of increasing your independence from the grid without spending too much.

Most marketers have online tools that can help you get the right size battery based on various factors. However, it is advisable to consult professionals for the best advice.

Customers with solar systems are increasingly adding battery storage to reduce their electricity costs or become independent from the grid. With better technology and prices getting lower every day, battery storage is becoming an appealing component to many solar power system owners.

This type of storage allows the customer to charge their batteries during the day and then discharge them when there is no generation. This permits homeowners and businesses to have a backup power source and save on electricity bills. In addition, you can sail through cloudy periods or other times when power generation is low.

Tired of breaking the bank just to keep up with the Joneses? Forget fancy cars and other status symbols. How about a way to maintain a friendly neighborly competition that actually involves saving money instead of spending? Americans have a wealth of resources at their disposal to empower families to cut back on energy consumption and reduce their electricity bills, but we don't do a stellar job of taking advantage of that information. Recent research, however, has shown that homeowners are more likely to take efficiency measures with their electrical work when they can compare their own consumption to that of their neighbors.

Whose Bill is the Lowest?

The experiment took place last summer, when the Vermont utility company Green Mountain Power worked with Opower, a software company that specializes in behavioral economics. During very hot days when air conditioning use was expected to be high, the utility reached out to customers with tips on reducing the amount of energy they need to power their home electrical work.

Afterward, the utility gave a report which ranked households in the neighborhood based on how well they had done on cutting back. By the end of the summer, electricity consumption among Green Mountain customers had dropped by five percent during hot days. That's some serious savings!

Peer Pressure at its Best

That five percent resulted from simple behavioral changes like bumping the thermostat up a few degrees and using curtains to block out sunlight during the hottest part of the day – no major investments or new equipment needed, just a little peer pressure. This research should be useful in helping understand what motivates people to save energy in order to develop more effective outreach programs for utility companies around the country.

One of the big takeaways is that the utility didn't give its customers any kind of incentives or payments to change their behavior – just the money they saved through efficiency, and the bragging rights of being more conservation-minded than their neighbors.

"Some of the decisions we make are not entirely rational, and they are due to a lack of context," Kevin Hamilton, Opower's vice president of marketing, said to Utility Drive, "and by providing that context you can encourage individuals to adjust their usage in ways that can benefit both the customer and the utility as well."

Little Changes Mean Big Savings

People come up with all kinds of reasons not to implement efficiency measures: It costs too much in initial capital, they are too busy to think about it, or they simply don't think the savings are worthwhile. But the reality is that even making small behavioral changes can add up in the long run.

If you want to decrease the cost of your electrical work and impress your neighbors, have a qualified home services technician perform an energy audit on your house to identify the most cost-effective ways for you to cut back.

Spirited lighting designs are trending toward the dark side, and that’s not just because it is Halloween.  Style spotters and top designers are embracing bold fashions and dramatic hues.  Take a look at the top three themes in the world of illumination…

1.  Deep, Dark Hues:  It is said to be a sign of the times that we are embracing rich, dark colors.  From politics to cultural rebirths, a positive vibe is in the air and we are changing it up with dramatic designs and darker hues.

“Momento De Mori” from Shannon Koszyk’s dramatic collection for Currey and Company features an Antique Nickel skull, black base and Inky Black parchment shade.

2.  A Cleaner Contemporary:   The ease of clean contemporary goes hand-in-hand with energy-efficiency and LED illumination.  From intricate geometric cutouts to textured Mercury glass compositions, the call for contemporary design has never been greater.

“Sovereign” table lamps from Dimond Lighting showcase Antique Mercury glass combined with energy-efficient LED illumination.

3.  Fearless Fashions and Surprise Twists:  Engaging new mediums run the gamut from natural palm leaf panels to a fusion of slate and metal.  Experimenting with hundreds of different textures, organic and synthetic materials, designers are coming up with new lamp shades, lamp bases and chandeliers that offer a magnificent blend of elements.  Novel lamp styles are making the A-list from designers who are not afraid to take a risk!

“Free Fall” from Kenroy Home introduces natural slate within a rugged iron lamp base for a statuesque presentation.

Lighting showrooms are abuzz with new lamps and chandeliers for the holiday season.  From High Point to Hong Kong, top lighting vendors are giving us plenty to celebrate.  Visit a Capitol Lighting showroom or 1800lighting.com to see the latest fixture fashions.

When we talk about replacing commercial and industrial lighting, we always try to alleviate the current costs that old and inefficient lighting fixtures incur while keeping (if not improving) our current quality of light in place. This is done with the obvious options such as:

With any lighting technology, whether that be Metal Halide, HPS, Florescent, or LED, they all suffer from something we call lumen depreciation.

Lumen depreciation is the process in which the total output of lumens a fixture produces decreases during its life. The rate at which a fixtures lumens depreciate can depend on a multitude of factors which include (but are not limited to): the type of lighting technology used, total hours used, and various other factors.

Did you know that florescent and LED lighting are typically the lowest to depreciate it’s lumens, while technology like Metal Halide and HPS are typically the fastest to depreciate it’s lumen output?

While LED is the the winner overall, florescent lights aren’t too far behind and not nearly as bad as Metal Halide or HPS lights. Here at MyLEDLightingGuide, we would recommend you get an LED for a lot more reasons then just slower lumen depreciation. email us directly.
