Which solar charge controller: PWM or MPPT?

classic-2-480x480

1. What they do

The PWM controller is in essence a switch that connects a solar array to a battery. The result is that the voltage of the array will be pulled down to near that of the battery.

The MPPT controller ( for example: Renogy MPPT charge controller) is more sophisticated (and more expensive): it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement, of the battery plus load. Thus, it essentially decouples the array and battery voltages so that there can be, for example, a 12 volt battery on one side of the MPPT charge controller and a large number of cells wired in series to produce 36 volts on the other.

The resultant twin strengths of an MPPT controller

a)       Maximum Power Point Tracking
The MPPT controller will harvest more power from the solar array. The performance advantage is substantial (10% to 40%) when the solar cell temperature is low (below 45°C), or very high (above 75°C), or when irradiance is very low.

At high temperature or low irradiance the output voltage of the array will drop dramatically. More cells must then be connected in series to make sure that the output voltage of the array exceeds battery voltage by a comfortable margin.

b)       Lower cabling cost and/or lower cabling losses
Ohm’s law tells us that losses due to cable resistance are Pc (Watt) = Rc x I², where Rc is the resistance of the cable. What this formula shows is that for a given cable loss, cable cross sectional area can be reduced by a factor of four when doubling the array voltage.

In the case of a given nominal power, more cells in series will increase the output voltage and reduce the output current of the array (P = V x I, thus, if P doesn’t change, then I must decrease when V increases).

As array size increases, cable length will increase. The option to wire more panels in series and thereby decrease the cable cross sectional area with a resultant drop in cost, is a compelling reason to install an MPPT controller as soon as the array power exceeds a few hundred Watts (12 V battery), or several 100s of Watts (24 V or 48 V battery).

3. Conclusion

PWM

The PWM charge controller is a good low cost solution for small systems only, when solar cell temperature is moderate to high (between 45°C and 75°C).

MPPT

To fully exploit the potential of the MPPT controller, the array voltage should be substantially higher than the battery voltage. The MPPT controller is the solution of choice for higher power systems (because of the lowest overall system cost due to smaller cable cross sectional areas). The MPPT controller will also harvest substantially more power when the solar cell temperature is low (below 45°C), or very high (above 75°C), or when irradiance is very low.

What we need is a dog friendly resort for the summer!

dog friendly beaches florida panhandle

Cape San Blas, Florida, is among the several remaining undeveloped treasures that shines brilliantly about the ring of shores that work across the shoreline of Florida.

Put Your Money Where Your Marketing Is

It wasn’t all that long ago that marketing experts were telling their clients that the Great Recession created great opportunities for companies brave enough to increase their investments in marketing.

So, why are companies doing exactly the opposite now that the economy is well into its recovery? The answer, it seems, is found in the shift to digital-marketing strategies.

Academic research dating back to the 1920s shows that companies which muscle-up advertising costs during recessionary times post sales gains when the economy bounces back. It makes sense, then, that marketing dollars stretch further when there’s less competition for advertising venues and less noise in the marketplace.

Gartner’s annual marketing survey found that marketing budgets for 2017 are expected to increase, compared to 2016. Chief marketing officers surveyed by Gartner said their organizations expected to invest 12 percent of their respective company revenues in marketing during 2017, up from 11 percent this year. (The full study is here; a subscription is required.)

It’s worth remembering that we’re eight years into the economic recovery. While the economy’s growth hasn’t been great, it’s been on a slow-and-steady upward path for a long time.

4 Strategies to Boost Customer Loyalty

20161222210412-gettyimages-620968065

To businesses, especially businesses in the B2C segment — loyal customers are more valuable than new customers. Even research has shown that loyal customers are worth up to 10 times the value of their first purchase. This makes it paramount for businesses to improve the number of loyal customers they have versus their one-off customers.

Also, given that the cost of acquiring a new customer is higher than that of maintaining an existing one, building customer loyalty is necessary for any business that aims to remain competitive. When a business has more loyal customers, it has the opportunity to put its marketing cost at a manageable size and spend more on improving the quality of its services and products. This is mainly because loyal customers are more likely to spread your business through word of mouth marketing (WOM), which, like customer reviews, is very critical to customer acquisition.

The following are strategies you can use to improve customer loyalty.

1. Improve on customer experience.

Customer experience ranks as one of the most important tools for increasing loyalty and advocacy. The secret to satisfying your customers lies in providing them with superior customer experience. A study conducted by the White House Office of Consumer Affairs found that 80 percent of consumers in the US are willing to pay more in order to get an improved customer experience.

By improving on the experience and satisfaction delivered to your customers, you’re erasing the chances of losing them to you competitors. In the age of improved consumer awareness, customers are now well aware of the powers that lie in the choices they make. Use this opportunity to your own advantage.
