Solar Panels That Get You Free Electricity
How about some free electricity ? Yes, you heard it right. A simple solar panel can get you free electricity for life. You could run a host of appliances at your home or office and we definitely need not mention the huge amounts of money that you will save over your lifetime on power bills. These modules have specified power ratings, that is, an upper limit on the maximum amount of electrical power they can generate; but you can always use as many modules as you need. I personally recommend using as many modules as required to power all sub 500 Watt devices, like the Plantronics CS510 – Over-the-Head Monaural Wireless Headset System.
At The Review Column, we believe in combing the market for the best products, which not only are the best in their performance, but also lead the race in terms of longevity and value for money. Here is a solar panel that you might find useful.
Renogy® RV Solar Kit 300W
A Solid 25 Year Performance Warranty
What less can you expect from a house like Renogy ? Had it not been for sound research and stringent manufacturing conditions, it would be virtually impossible to offer such a robust coverage. A product that comes with a 25 year performance warranty definitely speaks for itself. And that is not all. The product comes with a 5 year material and workmanship warranty for the panel. This alone should get you to fall in love with Renogy, but yes, we will get into its technical features also.
Guaranteed Positive Output Tolerance
Solar panels are usually sold with a balanced output tolerance, being positive on one side, while being negative on the other. For example, a panel rated for 100 Watts with a +/- 10% output tolerance typically means that the output, under standard conditions could vary from 90 Watts to 110. Renogy, eliminates the downside, i.e. the negative part of it. That simply means, that the rated output is the minimum that it will ever generate. The 3 piece 100 W Mono Solar Panel comes with a 0 – 3% output tolerance, which speaks of its sturdy design. Each module will never produce anything less that 100 Watts of electrical power, ever.
High Mechanical Strength
The Renogy RV Solar Kit 300 W can withstand heavy winds and snow loads. This translates to its versatility and makes it suitable for a wide range of weather conditions. It can be used in locations where wind speeds are typically higher than usual, for example, coastlines, or lakes. This, coupled with the unit’s ability to operate at temperatures as low as -40°C to as high as + 90°C, makes it almost weather proof. A combination that can suit most of the weather conditions we confront in our day to day lives.
Other Salient Features
- 3 Renogy 100 Watt Monocrystalline Solar Panels: High efficiency, durable, tempered glass, corrosion-resistant aluminum frames
- 30 Amp PWM Charge Controller w/ LCD Display, expandable to 400w for 12 volt battery system
- 3 sets of Sturdy Z brackets for Mounting – Unique design, bolts/washers included
- 40′ solar Adapter cable to connect solar panels to charge controller with MC4 connectors. 2 pair Branch connector
- 16′ Tray Cable (10 Gauge) to connect charge controller to battery, battery ring terminals included.
36 monocrystalline cells, IP65 rated junction box and Class C fire protection definitely add up to the strenths of this panel. The manufacturer also mentions a High Modules Conversion Efficiency which, plainly put, is the ratio of electrical output to the incident light energy (sunlight). We are not very sure about how high is really “high” and hence were not able to validate the manufacturer’s claim. Dust often accumulates on solar panels that reduces the quantum of light energy transferred, which in turn also reduces the output.
There are other variants of the the same panel available which you can view here. They come in different multiples of the 100 Watt module and differ in their accessories. The variants are :
RENOGY® RV Solar Kit 200W: 2pc 100W Mono Solar Panel + ViewStar 20A Charge Controller w/ LCD Display + 40′ MC4 Adapter Kit + 16′ Tray Cable + Z Brackets
