Full mAh capacity range of NiMH (the good chemistry) rechargeable batteries for Solar Lights are now available!
Solar lights for the home and garden come with pre-installed, pre-charged batteries from most (safe to say, all) manufacturers when you buy them online or directly at stores. What many people don't realize is that these rechargeable batteries will eventually run their course and lose all of their effective capacity after about 2 years of nightly use. These solar light batteries are almost always r...

The light wave of the future, switching to LEDs and what it means for cities.

Posted By: Your Solar Link Team on March 24, 2015 in Community Action, Creative Solar, Latest Technology, Solar News, World News - Comments: No Comments »

You’ve seen them. Maybe you didn’t know exactly what they were, but you’ve seen them. You’re driving along, listening to the latest Depeche Mode remix, and you notice that those street lights are different than what you remember from a decade ago. Yes, street lights are going LED (Light Emitting Diode). Some are going induction or halogen, but the point to make here is that they have been going away from that yellow HPS light that was prevalent a decade (or two) ago. However, as we have reached the middle of the second decade in the new millennium (yes, it’s 2015 already), technology has changed. And with it, we are going back to the white light at night to illuminate our streets, parking lots, and any other large exterior space.

Why go back to white light? First, it helps to give a true color to whatever is beneath the light (car, clothes, etc.) that helps with nighttime security (no more “they were driving a blue car, no green, no red….”; you get the picture). Second, it is closer to daylight color, so it is easier on the eye. And third, with LEDs, white light can be directed in a more controlled manner such that light pollution is greatly reduced as compared to their HPS predecessors. It is this third reason that interests cities and those who enjoy looking up to see the stars when outside of cities. As illustrated in the before and after images below, the lack of proper designs with HPS yellow lights created a haze of light pollution that spread beyond the ground they were intended to illuminate. The “after” picture shows how light on the ground is not compromised by switching to white LEDs, while the layers above the city are going back to dark, as it should. After all, we’re not trying to illuminate the air traffic above. Cheers.

Light pollution: HPS (top) vs. LED (bottom). The results speak for themselves.

Light pollution: HPS (top) vs. LED (bottom). The results speak for themselves.

So, the simple act of switching to LED fixtures for street lights is having a positive effect on security, near-natural light conditions and unwanted light pollution. Not only do we have these benefits, but LEDs outlast their predecessors by many years and use less energy to operate. Thus, the long-term costs of operation are greatly reduced and resources are preserved for future generations.

Now, it you want to take all that preservation, savings, efficiency and control of exterior lighting (cities, this is for you), then you can go off-grid with your street lights by cutting your ties to the utility company with the solar lights at SolTek Renewables. Their autonomous solar street lights include all the components to install a system that is comparable to (and often exceeds) industry standards while costing the user (and that would be you, the taxpayer) nothing in nightly operation. The only cost is that of a rechargeable battery (like the one in your car) replacement every 5 to 7 years (at today’s rate, that’s about $150 a battery).  Not a bad deal for generating illumination that is controlled and owned by the city (again, that’s you taxpayers), doesn’t involve wars over oil, isn’t affected by black-outs or brown-outs, is free from utility company fees and their nasty increases, is as reliable (if not more so) than the conventional/grid-tied lights, and is a 100% renewable energy light.

To give you an example, a solar street light from SolTek Renewables costs anywhere between $4,500 (for your typical 1-fixture light you see along the streets) to about $6,500 for a dual-fixture light (that you see along the median of a multi-lane highway). Typical installation costs run around $2,000 a light (depending on your contractor). So, to install a light where there was not one before will run you about $6,500 to $8,500. Compare that to grid-tied lights that cost even more after installation (trenching, wiring, labor, etc. are not cheap, nor free) and have energy costs every single night they are on (and look around, they are on in the daylight as well. Not efficient at all.) Furthermore, you can have your solar street light up and running in a matter of 2 to 3 months. Compare that to the decades (yes, decades!) of planning, political rhetoric, etc. with conventional grid-tied lights. If there ever were a no-brainer, solar street lights are it!

Solar on!

Back to the solar street light series, today’s episode – the solar panel.

We have been posting the components of the solar street lights at www.soltekrenewables.com. So far we have covered the 12-Volt rechargeable batteries, galvanized steel poles and CREE LED fixtures. Next up are the first point of contact for energy collection and generation: the solar panel. Solar panels are the point where photons from the sun (light) are collected, converted to electricity and transmitted via wires to the rechargeable batteries for storage and distribution at night to the LED luminaires. Sizes of solar panels have been steadily decreasing since their early years of widespread use. While the panels have been decreasing in size, they have also been increasing in efficiency. Efficiency is the amount of energy that is converted to usable electricity. Typical efficiencies run between 11% to 15%, with some companies offering panels at 18% efficiency.

Factors that can affect efficiency are reflective coatings on the panel to increase light infiltration, orientation of the solar panel relative to the sun, obstructions (shade from trees, buildings, etc.) and ambient temperature, to name a few. For the purposes of solar street lights, the optimum fixed panel position is tilted toward the south (for those of us in the USA). An angle of at least 20 degrees optimizes efficiency; however for those at higher latitudes, this angle will increase depending on your particular geographical location. For those on the equator, the optimum angle would be zero (as the sun crosses perpendicular twice a year), etc.

Solar panels for SolTek Renewables‘ line of solar street lights are higher on the efficiency rating, are minimally affected by temperature (as they do not rest on a surface such as a roof or ground that radiates stored heat from below) and can be coated with nano-coating applications to further increase prolonged clean panel surfaces in dusty locations. As for the aesthetics of a solar panel on top of the pole, the high efficiency and relatively small size of each panel do not detract from the design of the pole and fixture. Furthermore, it is nice to see that the energy used to light up your lights is collected with that solar panel on the top. A small reminder that you are now self-sufficient, off-grid and using a 100% renewable energy light where you own the energy that you use. An honest solution that is better for the environment and even better for your wallet.

Solar lights aren’t just for gardens and patios, they are also used for street lighting!

Posted By: Mario Villalobos on October 30, 2014 in Community Action, Creative Solar, Latest Technology, Solar News - Comments: No Comments »

When you think of solar lights, you may have visions of those lights found around homes and gardens that put out enough light to show you where they are and illuminate just a little bit of area around them on the ground. Furthermore, they usually charge enough to last only one night. So, if it is cloudy or rainy the following day, they may not emit as much free light as after that first full-day’s charge. Well, there are solar lights out there that are powerful enough to compete (and surpass) with the scale up to traditional street lights. SolTek Renewables is a company that supplies these powerhouses to customers around the globe.

With each light containing all of its own components to be stand-alone units, they are a practical and economic solution that are finding their way onto city streets and parking lots, eventually saving users (taxpayers) millions in electricity usage fees by going off-grid entirely. These solar lights are so efficient that they maintain system autonomy for anywhere between 3-6 days (typically longer). This means that if they charge under one day’s requirement (between 2-4 hours) of sunlight, then they will continue to illuminate as specified for 6 nights under total cloud cover. In regions such as the Southwest, a week with no sun is a rare occurrence. Additionally, the solar panels are efficient enough to gather some charge even under cloud cover. So, there is no stopping these street lights from operating as a serious contender to grid-tied lights. Users are guaranteed that the lights use renewable energy (local utilities can’t guarantee that 100% of their electricity comes from renewable resources) and that each light has a zero-carbon footprint.

German town of Feldheim is off-grid using wind, sun and biogas (pig manure): Yes, it can be done!

Posted By: Mario Villalobos on October 26, 2014 in Community Action, Creative Solar, Solar News, World News - Comments: No Comments »

The small (150 people, yes, it is small) village of Feldheim (located 50 miles southwest of Berlin, Germany) is off the grid for their power and energy requirements. In fact, they produce so much energy with their wind farms, solar panels and biogas (via pig/cattle manure and shredded corn) during the colder months of the year) that they are able to sell back their excess energy to the national gird. A simple solution to an unnecessarily complex problem, and it is starting with small towns and villages around the globe.

A great advantage to having smaller towns and villages generate their electricity is the elimination of high-voltage transmission lines throughout the countryside. If a town proves itself sustainable, then there is no reason to “wire in” the electricity demands of said town. True sustainability and appropriate technology will be the wave of the future for those who progress toward a positive and environmentally-friendly future. Efficiency and passive design will also help to usher in the wave of the future of energy independence and a pleasant environment for all creatures great and small.

First exposition in Central America focused entirely on solar power.

Posted By: Your Solar Link Team on October 24, 2014 in Community Action, Creative Solar, Latest Technology, Solar News, World News - Comments: No Comments »

ExpoSolar, which takes place Oct. 31- Nov. 1 in downtown San José Costa Rica, will be the first event of its kind in Central America to focus only on solar power. It is organized by the Costa Rican Solar Energy Association (Asociacion Costarricense de Energía Solar, or ACESOLAR). During the event a wide variety of firms will present their products, including systems for heating water and photovoltaic systems for generating electricity.


EXPO SOLAR in Costa Rica – October 31-November 1, 2014.

Costa Rica is perhaps one of the most technologically advanced nations in Latin America.
Currently 50 companies are involved in the solar energy business in Costa Rica. They offer services in a number of areas, including consulting, construction, design, installation and distribution, among others.

TEC students, who recently won the prestigious prize for “Favorite House” with their “Casa Tropika” at the Solar Decathlon Europe competition this year in France, also will be present. This was an impressive win not just for the 35 students who put the project together, but also for the country, which beat out submissions from all over the world. The winning Costa Rican entry is a single-family, intelligent house for senior citizens that not only feeds the dog, but also automatically dispenses medications to residents, and of course, is completely solar.
