Appliances can make for exciting and valuable additions to your home; however, they use a lot of electricity and can ultimately take a toll on your electrical system. As a Plano TX electrician is called to help install the appliance, the importance of appliance installation safety is ignored and the awareness of potential dangers and mistakes in installation is minimized. As a result, things that at the time of installation seemed trivial in the long run can cause significant problems.

LED sign lighting provides years of illumination and low energy costs. sign modules that consume 50mA of power each. Required materials differ depending on sign size, module size, length of wire between modules, current draw, and lumen output.

Materials:

1. First, measure your sign. Although we recommend spacing module rows 3 inches apart, it’s ultimately up to you. If you want a brighter sign, place them closer together and vice versa for a dimmer sign. With the recommended 3-inch spacing, a 4-foot square sign would need 150 modules (15 rows of 10). Again, the quantity of modules needed  is based on many factors and can differ.

These LED sign modules are available in custom lengths of up to 20 modules per strand. Order 60 feet (4 feet x 15 rows) of stranded modules, and cut the strand after every 10 modules. Each strand can be cut to make two rows.

2. Next you’ll need to order a power supply that’s rated for the combined wattage of all sign modules. To ensure that you don’t overwork the power supply, confirm that the total wattage of your modules is at least 20 percent less than the power supply’s rated wattage.

An easy way to calculate this is to multiply the total wattage of your combined lighting by 1.2. In the 4-foot sign diagram, there are 150 modules with a current draw of 50 milliamps (mA) each. Since current draw is given in milliamps, multiply that number by voltage and move the decimal 3 places to the left to get wattage. This module consumes 50 mA and has 12 VDC operation, so it consumes 0.6 watts (50 x 12 = 600). Next, multiply 0.6 by 150 to get a combined wattage of 90 and multiply that number by 1.2 (90 x 1.2 = 108) to determine which power supply you’ll need. Since the result was 108, you will need at least a 120-watt power supply.

3. Next on the list is wire to connect all your sign module stands to the power supply. For a 4-foot sign, you’ll need 4 feet of 18-gauge two-conductor wire to serve as your main line plus enough to cover the distance between your power supply and where it will be wired into an electrical system. You’ll also need dual-channel T-tap wire splice connectors for an easy connection to your main line.

Before you begin working on your sign, turn off power to the area.

4. If there isn’t one already, drill a hole in the back of your sign as an exit point for your wire.

5. Use a tape measure or ruler to plot your row spacing. Leave space on one side of the sign for your module-to-main-line connections. Mount the sign modules using their double-sided adhesive and/or screw holes.

6. Insert the end wires of each sign module row into the T-tap splice connector, and clamp the other end of the connector onto the main line. The splice connectors eliminate the need to strip wire insulation.

7. Use double-sided foam tape to secure each T-tap splice connector to the inside of your sign.

8. Reattach your sign’s front cover.

9. Connect the main line to your power supply, wire the supply into your electrical system, and restore power to the area.

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.
