General questions:

  • Why do we need Sol Chip’s Everlasting Solar Battery™?
    In all cases that battery replacement cost is high, there is a need to avoid such replacements. Sol Chip’s Everlasting Solar Battery™ can provide the solution for it.
  • How can I know how many units I need for my application?
    Sol Chip can provide this information based on the power consumption and the light conditions of your application.
  • Can I get power 24 hours a day?
    Yes. Sol Chip’s Everlasting Solar Battery™ can charge energy storage (like capacitor) during light time and provide power for 24 hours a day.
  • Can I get peak power higher than the Sol Chip’s Everlasting Solar Battery™?
    Yes. Sol Chip’s Everlasting Solar Battery™ can charge energy storage (like capacitor) with relatively low average power and the capacitor can provide the required peak power to the application.

Device performance:

  • What types of energy storage are supported Sol Chip’s Everlasting Solar Battery™
    Sol Chip’s Everlasting Solar Battery™ can support capacitors and super-capacitors, thin film batteries and rechargeable batteries.
    Sol Chip’s Everlasting Solar Battery™ can also be used to extend primary battery’s life time.
  • Why efficiency doesn’t matter?
    In such low power applications as demonstrated in the Applications page, the light conditions can vary in few orders of magnitude. For example, daylight condition varies by more than 100X between summer clear day and winter cloudy day. Few percent higher efficiency will not have any impact on such solution. The system should be designed for the worst-case conditions.
  • Why small is better?
    In many applications, size is critical from varies reasons – for example, in-house devices that should look nice, security devices that should not be noticeable etc.

Package or Die

  • How the product can work inside a box?
    The unit can be soldered directly to the main PCB. All it needs is to be exposed to light. Few options are available:
    § The entire box could be transparent
    § The box can have window (as the smartphone camera has small window).
    No need for special lens on this window – just simple glass
  • Is your Sol Chip’s Everlasting Solar Battery™ suitable for current surface mount PCB assembly technologies?
    Yes. We provide our device in a standard packaging (open cover) on a tape-n-reel to meet with any pick and place machine for automatic assembly.
  • Can we buy Sol Chip’s Everlasting Solar Battery™ in a die format and not in a package?
    Yes. We provide our device either in a die format or in a standard packaging (open cover).
