“Be prepared” – the motto of the Boy Scouts of America – is just as applicable to any person, or organization. The purpose of this white paper is to help tribal communities/ reservations, and other US Government (USG) entities “be prepared” to install solar powered lighting systems.

Private University Magazine recently published an article on Safety and Sustainability through Solar Lighting.

I wanted to share a letter from the Chairman of the Taro Fisheries Cooperative who received donated 20/20™ solar lighting systems courtesy of our Chairman of the Board, Michael Sonnenfeldt.
Now that spring has arrived (feel free to CHEER about it!) we all look forward to sunshine, warm air, blossoming flowers and of course...Spring Cleaning. This is the perfect time of year to inspect your solar lighting systems to keep them optimized for worry-free illumination.
Just over three years, Sol set a goal to create a solar lighting system that offers performance, durability and energy efficiency at the lowest installed cost.
In principal, it’s 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 produce power. In addition to large capacity batteries and solar panels, solar outdoor lighting systems also incorporate 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 sun is a direct source of energy. Using renewable energy technologies, we can convert that solar energy into electricity. Solar powered lighting is a relatively simple concept. In a basic way, the system operates like a bank account. Withdrawals from the battery to power the light source must be compensated for by commensurate deposits of energy from the solar panels. As long as the system is designed so deposits exceed withdrawals on an average daily basis, the battery remains charged and light source is reliably powered.
