FAQ

Type of solar panels

  • Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Monocrystalline solar panels are also the most expensive.

  • Polycrystalline (or multi-crystalline) silicon produces the next most efficient type of solar cell and is the most popular choice as it provides an excellent balance of performance and economy. Recent improvements in polycrystalline panel technology are bringing these modules closer to monocrystalline in size, efficiency and heat tolerance characteristics. The European market has now adopted polycrystalline as the standard.

  • Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so.

 How many solar panels do I need

The amount of solar panels you require will be determined by the amount of charge that you need to return to your system during the sunlight hours of each day.  For a 12V system, if you need to replace 100A/h of charge to your batteries each day, and you have 8 sunlight hours in each day you will need:

100AH x 12V = 1200WH
1200WH / 8H = 150W of solar panels.

In reality it is recommended that you always overrate your requirements by at least 20%, therefore you would need 120W solar panels.

How to maintain & clean solar panels

  • Clean the surface of the device with a soft, slightly moistened cloth or a dry brush only

  • Do not use corrosive cleansing agents or chemical solutions since this may damage the housing surface or impair operation

  • Keep the solar cell free of dirt, debris and snow, or the battery will not charge properly. This may also shorten battery life or cause a malfunction


Useful tips on using solar lights

  • It is recommended to place the solar lights under the sun for recharging even it is not being used

  • This helps prevent from dead battery and maximize product life

  • If the solar lights is not being used for a long period of time, please charge for at least 10 to 15 hours by the sun before use
