I. How does Solar Power Lights Work?
In principal, its simple. A solar panel converts light to electricity. During daylight, even on cloudy days,this solar generator (solar panel) charges long-life batteries, which store the energy until needed. Thus,the energy of the sun is harnessed to product power. In practice, of course, solar outdoor lighting is a little more complex. In addition to large capacity batteries and solar panels, the system also incorporates sophisticated proprietary charge
regulators,which stop the flow of solar generated electricity when the batteries are fully charged, and then resume charging when more power is needed.The key to solar outdoor lighting is the solar power pack, which houses photovoltaic solar panels, a proprietary microprocessor control system and batteries. It is attached to specifically designed lights having super reflectivity and high energy ballasts.

II. How Dependable is Solar Power Lights?
Very dependable. In fact, if theres enough sunlight to see reasonably well, theres enough to collect andstore energy even if its raining. The Gaia Solar Power Lights System can store enough energy to operate five or more consecutive days without sun. Whats more, solar power lights are virtually maintenance-free, since the batteries require no water or other regular service. Unlike some systems that are assembled from off the shelf parts not designed for solar service, Gaia Solar Power Lights systems are assembled from components specifically designed for solar. The solar panel itself is backed by a 15 year warranty the strongest in the industry and with our new CCFL bulb, the entire Gaia solar power lights systems can reach a guarantee of four (4) years.

III. What Advantage do Solar Power Lights Have?
Gaia Solar Power Lights systems provide unmatched convenience, reliability and efficiency. Each Gaia Solar Power Light has its own power plant so you dont depend on far away generating stations, transmission lines, substations, switches and transformers. Since each solar electric light operates autonomously, every light is programmed through its own control system, to turn on and off as needed.And, in the unlikely event that an individual solar power light fails, no other lights are affected. Solar systems outperform traditional wired systems hands-down. In a solar installation, initial costs incurr for the self-contained energy collection and storage system. But after that, the energy itself is free! When compared to the traditional systems cost for cable, trenching, metering equipment and construction plus electric bills continuing forever the solar systems advantages can be dramatic and immediate.
1. No trenching, no metering, no wiring
2. Cost savings from day one due to ease of installation
3. People feel safer when areas are illuminated
4. Can be installed in the most remote locations
5. No cost for daily operation
6. Free energy once installed no electric bills.
7. Not connected to grid power will work even when electric power is out
8. Will turn on even after cloudy days

IV. How to Determine A Solar Power Light System?
Based on particular information, a series of calculations are run that will determine the appropriate size for the solar panel array. This process is called sizing a solar system. Only after a system has been sized can the specifics of the system and price be determined.
You Determine:
1. Geographic Location: Different geographic locations have different solar insolation which 
    determines the size of the required solar panels
2. The Application: Different applications need different amounts of light
3. Preferred Bulb:LED, Low Pressure Sodium
   (LPS) , Polar lamp or High Pressure Sodium(HPS)
4. Run Time (Duration of the Load): Number of hours you need the lights to be on each night.Examples:
    Dusk to Dawn, 12 hours, 6 hours, split time controllers (4 hours after dusk & 2  hours before dawn), etc.
5. Fixture Model: We have a variety of standard fixtures available.

We Determine:
1. Sun Hours based on your location: Different geographic locations have different solar
    insolation (sun hour factor) which will determine the size of the solar panel(s) needed.
2. The Bulb Size: Based on the amount of light you need for your particular application or
    specific footcandle requirement on the ground
3. The Size of the Required Solar Panels: Solar panels typically come in a variety of sizes.
    We always calculate at least a 10% reserve and round up to the next higher panel size.
4. The Size and Number of Batteries: Our systems are sized to work after 3 dark or cloudy days.
    Additional battery back-up can be added if needed. In addition, we build in a 20% safety factor.
5. Optimal pole spacing and placement to match your specified light requirements.
      We take high quality and clients satisfaction as our basic ,We make the products with best quality-cost ratio.
