The electronic ruler is designed for interior designers . Because it can switch many modes we don't have to carry or produce so many rulers. When we use it, it can get energy from the transparent solar panels. In addition, we will not use a ruler on no light environments.
This new type of transparent solar panels only use 20% of silicon, but it can achieve 20% energy conversion rate setting to traditional solar panels more than twice . The cost per watt of electricity is only 1 / 4 compared to traditional .
