A Brief Idea On Different Sizes Of Commercial Solar Systems

Are you planning to install commercial solar systems? Then you must have some idea about the various sizes available. After analyzing the cost and profit of each size, it’s your call to choose the right one for you according to your business size. Here is a head start for you:

4kW/4.5kW/5kW System: It includes 10 to 20 solar panels. The installation & modulation is going to cost you approximately $7,900 with the hope of saving around $1100 each year. It can add up approximately $23,000 in course of time (like 15-20 years later). Worthy for a start-up business because it can serve 2-4 people.

7.5kW System: If your business has 3 or more employees, take a step forward to 7.5kW. It will cost you around $13,100.00 with a usage of 28.7kWhs and 45.3kWhs.

10kW System: With the expectation of earning $2800 each year it will cost you around $28,600. Considering the return rate against the costing it sounds great. It usually generates 39kWhs every day in sunny day and more or less depending on the weather.

25kW System: Is business getting more larger? Move to 25kW system – where installation cost is about $71,400. It’s perfect for large business like warehouse with an assurance of handsome return rate like $9,000.

50kW System: Each year it’s going to produce about 44,000kWh of electricity. It will cost around $94,100 with 17% investment rate, means you can save about $28,200.

80kW/100kW/200kW System: For a very large business, 100kW or above solar systems can be used. The cost mainly depends on the installing process or installer and the average earning rate is over $35,700.


Now go solar starting with the wise decision of installing the perfect sized solar system for your business.

Why Should You Choose LED over CFL and Incandescent Lighting

Making comparisons between LED lights, incandescent lights and CFLs is still something many people wish to do before they make the shift from a standard incandescent light to the new, energy saving compact fluorescent lamp or LED light. The comparison helps you out to choose the perfect product according to your needs.

Several factors need to be compared before making the decision as to which products to use and while making choices over lights, consumers need to compare a number of specific areas like the lifetime, energy cost, wattage and the efficiency of the lights and then choose accordingly.

	LEDs	Incandescent	CFLs
Lifespan (on average)	50,000 hours	1,200 hours	8,000 hours
Wattage	6 to 8 watts	60 watts	13 to 15 watts
Annual Operating cost	$32.85/year	$328.59/year	$76.65/year
Carbon Dioxide Emissions	451 pounds/year	4500 pounds/year	1051 pounds/year
Contains the TOXIC Mercury	No	No	Yes - Mercury is very toxic to your health and the environment
Durability	Very Durable - LEDs can handle jarring and bumping	Not Very Durable - glass or filament can break easily	Not Very Durable - glass can break easily
Heat Emitted	3.4 btu's/hour	85 btu's/hour	30 btu's/hour
Sensitive to humidity	No	Some	Yes

Brightness (Lumens)	LEDs (Watts)	Incandescent (Watts)	CFLs (Watts)
450	4-5	40	9-13
800	6-8	60	13-15
1,100	9-13	75	18-25
1,600	16-20	100	23-30
2,600	25-28	150	30-55

When the above charts are taken into consideration it is found that according to the statistics, LED lights are much more efficient compared to their Incandescent and CFL counterparts. LED lights are eco-friendly as well. In terms of brightness, LED lights tend to give out more light and expend less energy, resulting in less power usage than Incandescent and CFLs.

Long Life

The life of LED light is projected to be around 50,000 hours, compared to 1,200 hours for an incandescent bulb and 8,000 hours for a compact fluorescent light. There is a huge difference in the life span of LEDs vs the other options available.

Effectiveness

LED lights are much more energy efficient than that Incandescent lights or CFLs as LED lights tend to convert about 80% of electrical energy into light giving out 20% as heat energy whereas the traditional lights convert 20% of electrical energy in to light energy and the rest 80% is lost as heat energy. The long operational life time acts as a multiplier and helps achieve even more energy efficiency.

Eco-friendly

LED lights contain no toxic materials and are 100% recyclable. The long operational life time span of the LED lights means that one LED light bulb can save material and production of 25 incandescent light bulbs which can be considered to be a huge step towards a greener future!

Durability

LEDs are enormously durable and can make a very good outdoor lighting systems as these are resistant to vibrations, shock and external impacts.

Brightness

Since LED lights convert 80% of the electrical energy into light energy compared to other traditional lights it can be claimed that in terms of brightness LED lights take the lead.

Low-Voltage

A low-voltage power supply is adequate for LED lights which verifies the fact that LED technology act as a big advantage when used in remote or rural areas.

When people want to change their lights they tend to think about the initial price but don’t think about the fact that they may only have to outlay a greater amount of money once to enjoy the benefits much longer. The above comparisons between LEDs vs. Incandescent vs. CFLs justify the popularity of LED lights and why they are a bit higher in price. Spending more money on LED lights now can is sure to be beneficial for you in the long run.
