This is the final post in our series on solar street lights from SolTek Renewables. We covered everything from energy collection (solar panels) to energy storage (rechargeable 12 Volt batteries). Now we will focus on energy distribution. This is maintained by a smart controller that is located near the base and inside of each light pole (poles are hollow).
The smart controller has a few functions:
1. The smart controller is a gateway device that is located between the solar panel and the rechargeable battery. The controller will monitor the current of electricity going into the battery to ensure that the battery is not overcharged.
2. Once the sun has set, the smart controller recognizes the drop in current and automatically reverses the flow of electricity out of the rechargeable battery and into the CREE LED luminaires.
3. Smart controllers can be set to energize the LED luminaires in several modes such as split night (full output for first 5 hours and then to 40% for remainder of evening), full output (which will lessen the autonomy from 5 to about 2 or 3 nights), to full brightness with automatic shut-off (this setting may extend the system autonomy well beyond 5 nights).
4. Once the sun starts to rise at dawn, the smart controller will repeat the cycle of energy collection via the solar panel and direct it to the rechargeable battery.
It’s that simple! Now that we are able to collect, control, and distribute our own free energy from the sun, the applications are becoming limitless. With all the components designed into one unit, the solar street lights from SolTek Renewables are without a doubt the most economical, environmentally friendly, reliable and practical solution for almost all exterior illumination projects in most of the world. 2015 is here and so is SolTek Renewables!

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.
