Solar powered LED sign lights are the perfect solution for illuminating signs in remote locations, or areas where it’s too costly to access mains electric power. A solar system can boost a company or organization’s green image and also be a cost effective alternative to trenching cables, which can costs thousands alone not including the monthly electric bill and meter costs.

Solar panels harness the energy of the sun by using photovoltaic cells to generate direct current (DC) electricity. Solar panels vary in size, efficiency, cell type, and cost, so choosing the right ones will depend on your application and specific needs.

According to the Solar Energy Industries Association, the cost to install solar has dropped by more than 70 percent over the past 10 years. Currently, the cost per watt to install solar is around $3. In addition, solar panel users can often lock-in electricity prices and once panels are paid for, it’s almost free to use.

SEPCO’s solar sign lighting systems are an efficient means to provide lighting without the need for standard utility power. Every system provides cost savings by eliminating the need to trench standard electric wires for installation and providing no electric bill for the life of the system.

However, in real conditions of use, especially in cities, dirt and dust on the panel reduce its energy production. Elminir et al. (2006) found a decrease of between 6% and 20% in the output power due to dust (17.4% for a 45° tilt angle of the solar panel).

Renewable energy has entered a virtuous cycle of falling costs, increasing deployment and accelerated technological progress. Solar PV module prices have fallen by around 90% since the end of 2009, while wind turbine prices have fallen by 55-60% since 2010.

From around $90/MWh in 2014, the latest power purchase agreements (PPAs) — the long-term financial guarantees underpinning the volatile renewable sector — have fallen towards $55MWh at the

John Smith is a homeowner in California looking to reduce his electric bill by going solar and he decided to call an installation company that he found on the internet. The next day, a rep from XYZ Solar came out to his house and, after looking at his electric bill, told John that he would need an 8.5kW PV system to offset 100% of his past 12-month usage.

The cost of solar cells is still $5.22 a "watt," where a "watt" (in solar hype speak) is something that runs at 15% of capacity. That comes out to $5.22/0.15 = $34.80. I'm a liberal. This means that I believe that poor people count too, that a solution valid for some.
